2. Reading Deeply: Interpreting Literary Texts in Primary and Intermediate School Classrooms
- Author
-
McDowall, Sue
- Abstract
In this article, I describe the challenges students faced in interpreting literary--or fictional--texts in the National Monitoring Study of Student Achievement in the English learning area. I explain why it is important for students to learn how to interpret literary texts at school and consider why they might struggle with this important skill. I then describe how teachers might help students to build their interpretive capabilities.

McDowall, Sue
- Abstract
In this article I explore a challenge identified by teachers involved in a recent research project on curriculum integration. Teachers described this challenge as how to balance the need to "cover" "The New Zealand Curriculum" with the need to support student agency. I describe how teachers saw this challenge, and the different ways they responded to it. I end by considering how our conceptions of knowledge might contribute to the ways in which we might think about and address this challenge.

- Abstract
The national COVID-19 lockdown during school Term 1 and continuing in Term 2 2020, provided a unique context to investigate?children's experiences of informal, everyday learning in their household bubble. In Terms 3 and 4, 178?children in Years 4-8 from 10 primary schools agreed to participate in a group art-making activity and?an individual interview about their experiences. The research adopted a strengths-based approach on the basis that most children are capable actors in their social worlds. This report documents children's accounts of the multiple ways in which they?negotiated the novel experience of forced confinement over a period of several weeks with family and?whanau. Seven themes emerged from qualitative analysis of the interviews with children: (1) Learning new structures and routines in the bubble; (2) Learning from and with whanau; (3) Learning about and through language, culture, and identity; (4) Learning through life events; (5) Emotional dimension of learning; (6) Learning about and through digital technologies; and (7) Self-directed and self-regulated learning.

New Zealand Council for Educational Research (NZCER) and McDowall, Sue
- Abstract
This report presents the findings of a small exploratory study carried out in 2021 by the New Zealand Council for Educational Research (NZCER) for the National Library of New Zealand | Te Puna Matauranga o Aotearoa. The project is part of a wider suite of six studies commissioned by the National Library as part of their Communities of Readers initiative. This initiative foregrounds the benefits of reading for pleasure and the equitable distribution of these benefits across all communities in Aotearoa New Zealand. The purpose of this study was to investigate the possible associations between the personal reading practices of teachers who read for pleasure and their engagement with students around text in their schools and classrooms. Two main questions guided the research: (1) How do teachers who read for pleasure describe their engagement with text and the impact of reading on their lives? and (2) How do teachers who read for pleasure describe their engagement with students around text in their classrooms and schools and the impact of this engagement? The research involved interviewing nine primary and intermediate teachers known to be passionate readers. Findings show: (1) There were more similarities than differences among the teachers as readers; (2) Teachers had similar aspirations for their students as readers; (3) Teachers used a range of strategies to realise their aspirations for students; (4) Teachers supported reading for pleasure across the school; and (5) Teachers observed increased engagement and achievement in reading.

Cameron, Tracy A., Taumoepeau, Mele, Clarke, Kristina, McDowall, Philippa, and Schaughency, Elizabeth
- Abstract
This study describes trajectories of early literacy skill development of 99 children (n = 55 boys) in their first year of primary school in New Zealand (NZ). Children were assessed twice weekly for 8 weeks on Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2011) First Sound Fluency (FSF) and AIMSweb Letter Sound Fluency (LSF; Shinn & Shinn, 2002), with other early literacy and beginning reading skills assessed before and after progress monitoring. FSF and LSF growth trajectories were modeled separately. Multilevel modeling indicated improved performance; however, growth mixture modeling indicated 3 growth trajectories (i.e., latent classes; FSF and LSF, respectively): typical (77.6% of children, 65.7%), developing (10.8%, 14.6%), and limited progress (11.6%, 19.7%). Beginning of year screening was sometimes associated with latent class membership, whereas latent class membership differentiated mid- and year-end literacy skills. Results support progress monitoring of early literacy skills within the NZ context to aid earlier identification of children at-risk for difficulties with reading acquisition.

7. Teaching for Present 'and Future' Competency: A Productive Focus for Professional Learning
- Author
-
Hipkins, Rosemary and McDowall, Sue
- Abstract
The key competencies are a potentially transformative feature of the New Zealand Curriculum. However, the way in which they have been understood and implemented in schools points to tensions and challenges that may prevent them from acting as agents of curriculum change. One recent researcher/practitioner partnership developed materials that show how a close interweaving of key competencies and traditional subject learning might transform the taught curriculum. Analysis of the practice of the teachers who contributed to this project suggests that refocusing teacher thinking about purposes for learning is likely to be a critical change lever. A clear focus on students' present and future needs must be part of any re-imagining of purposes for teaching and learning, and hence of the taught curriculum.

New Zealand Council for Educational Research, Wylie, Cathy, McDowall, Sue, and Ferral, Hilary
- Abstract
How do you support busy school leaders and teachers to take advantage of the strong body of evidence now available about effective teaching, school, and leadership practices? How do we grow our understanding of teaching, school, and principal leadership practices nationally, so that the system can learn and improve? What are the strengths and needs of our educators and schools? And are new policies having their intended effect? The Teaching, School, and Principal Leadership Practices Survey tool (TSP)1 was designed to meet these needs. This report describes the aggregated responses for the schools that used the TSP in 2018. Compared with the national school picture, schools using the TSP included fewer small, rural, decile 1-2 schools, and schools with high Maori enrolment.

New Zealand Council for Educational Research, McDowall, Sue, and Hipkins, Rosemary
- Abstract
This report presents the findings from a research project on curriculum integration in New Zealand schools, carried out by NZCER in 2018-19. The purpose of the research was to explore teachers' rationales for curriculum integration; the approaches and practices used to integrate curriculum; and the learning opportunities such approaches provide for students. Research questions include the following: (1) What sorts of outcomes do teachers envisage when they integrate subjects (i.e., what are their purposes for doing so)?; (2) What sorts of topics are used to integrate learning across learning areas?; (3) How is integration achieved in practice? (For example, how are different learning areas differentiated and/or juxtaposed?); (4) What is taught about the knowledge-building (epistemic) processes of each discipline?; and (5) What learning opportunities does curriculum integration afford students, and do the opportunities differ for different groups of students, including those traditionally underserved by the education system?

New Zealand Council for Educational Research, Bolstad, Rachel, and McDowall, Sue
- Abstract
This report discusses the potential of games to support learning, and what innovative game-based (or "gameful") learning and teaching practices can look like in a range of New Zealand school settings. Over 2 years, we undertook fieldwork in 14 schools, interviewed 21 teachers and more than 100 students ranging from Year 3 to Year 13. We looked at learning and teaching practices involving all kinds of games (physical, role play, tabletop, and digital), and how games, game design, or gamification fitted in with teachers' curriculum and pedagogical goals. We also undertook an extensive review of New Zealand and international literature, and convened workshops and a national conference. A key finding is that educators who are open to working with the wide-ranging affordances of games apply creative and nuanced pedagogical thinking to the design of gameful learning. This generates an array of curriculum-linked learning opportunities, with an emphasis on "front end" aims of "The New Zealand Curriculum" (Ministry of Education, 2007), development of key competencies, and creating an inclusive learning environment that supports and enables diverse strengths and interests to emerge, benefiting individuals as well as the collective.

New Zealand Council for Educational Research, Wylie, Cathy, McDowall, Sue, Ferral, Hilary, Felgate, Rachel, and Visser, Heleen
- Abstract
New Zealand now has its first national picture of teaching and school practices, and principal leadership in English-medium schools. The Teaching and School Practices Survey Tool (TSP) is an online survey tool designed for schools and Kahui Ako to inquire into their teaching, school, and principal leadership practices. The TSP tool was developed in 2017 and made available for use in Terms 2 and 3 of that year. The national picture presented in this report draws on the 2017 aggregated data. The tool was commissioned by the Ministry of Education to provide: (1) school-level data that can be used by schools and Kahui Ako in review and planning to improve teaching and leadership capability; and (2) national data that can be used for evaluating the impact of policy, initially the introduction of Kahui Ako and changes to professional learning and development. The items in the TSP draw on robust research evidence about practices that are linked to desirable student experiences of learning and student outcomes. The items are consistent with The New Zealand Curriculum, ERO's school evaluation indicators, and the Standards for the Teaching Profession.

New Zealand Council for Educational Research, McDowall, Sue, and Hipkins, Rosemary
- Abstract
This is one of two papers developed for a Ministry of Education (MOE)-funded project, Competencies in New Zealand Council for Educational Research (NZC). The first paper draws on archived policy discussion papers to document the provenance of the NZC key competencies. This second paper analyses a series of research projects to describe how understandings about key competencies have developed over the decade since NZC was published. The key competencies have attracted considerable research attention over the decade since "The New Zealand Curriculum" ("NZC") was introduced. In this paper the authors report on an inquiry into the contribution this research effort has made to understanding: (1) what key competencies are (their nature); (2) how they should be included in a local curriculum (their weaving together with other curriculum components); and (3) how they should impact the intended learning (their role). A collection of relevant research was used to define four phases in the ways that key competencies have been understood and enacted in the overall school curriculum. This report describes the main conceptual and practical shifts during each of the four phases. Assessment implications of these different ways of thinking about the nature and role of key competencies in the curriculum are also outlined.

McDowall, Philippa S. and Schaughency, Elizabeth
- Abstract
School efforts to engage parents are posited to influence whether and how they are involved in their children's schooling. The authors examined educators' engagement efforts in beginning reading, their subjective evaluations of engagement practices, and beliefs about parent involvement, in two stratified samples of New Zealand elementary school educators. They explored whether educators' ratings supported multidimensional and multitiered theoretical models of engagement. The authors invited responses from elementary principals and teachers, given their different roles in the nested ecology of schools and relationships with parents, and examined associations between pairs of principals and teachers working in the same school. Finally, the authors examined relations among educators' engagement efforts, evaluations of engagement practices, and beliefs about involvement, and school characteristics including community socioeconomic status, size of school population, ethnic composition of school population, community size, and geographic region.

New Zealand Council for Educational Research and McDowall, Sue
- Abstract
We know it is important to help students to critically engage with texts like books and movies. We want them to become skilled at questioning what's in front of them, and understand how texts are constructed, and whose interests are served. We also need to develop their critical literacy as they interact with games. So, how can we help them do this? In this paper I draw on the experiences of teachers and students in the "Games for Learning" project to explore how we can help students to develop critical games literacy through opportunities to play, question, review, modify, and make games.

- Abstract
The purpose of this study was to clarify equivocal findings in the parent-involvement literature and examine novel interactions in a New Zealand context. Specifically, this study tested direct effects of school year, parent education, family structure, and child gender on parent involvement in elementary school. In addition, interactions between parent, family, and child characteristics were explored as moderators on the relation of school year and parent involvement. Participants were 421 primary caregivers of children attending their first through final years of elementary school on New Zealand's South Island. Structural equation models were used to detect direct and interaction effects. Findings revealed statistically significant direct effects for several parent, family, and child characteristics examined. No interaction effects were found. Implications and future research directions are discussed.

Schaughency, Elizabeth, McLennan, Kathryn M., and McDowall, Philippa S.
- Abstract
A New Zealand (NZ) version of Word Identification Fluency (NZWIF) was administered to 120 children in their second school year at the beginning, middle, and end of the year, along with a curriculum-based measure of oral passage reading fluency at mid- and end-year. Outcome measures included standardized and high-stakes school-used indicators of literacy achievement. NZWIF generally correlated robustly, concurrently and predictively with criterion measures. Overall, NZWIF performance improved across the year. Performance, and change in performance, varied for students who were and were not judged to be making adequate reading progress. Although at-risk readers performed more poorly at each time point, predictive relations of earlier NZWIF performance, subsequent NZWIF growth, and the interaction of earlier performance and growth to later outcomes varied as a function of proficiency and time of year. Findings extend the evidence-base for curriculum-based word reading measures in beginning reading, and reinforce the need for a developmental approach to assessment research and practice.

Teaching and Learning Research Initiative (New Zealand) and McDowall, Sue
- Abstract
This is the second publication in the Teaching and Learning Research Initiative (TLRI) Project Plus series. Project Plus aims to inform questions of policy and practice by synthesising findings of educational interest from projects funded by the TLRI. This Project Plus focuses on literacy in the early childhood education (ECE) and school sectors.The TLRI provides government-funded support for research that builds knowledge about teaching and learning in Aotearoa New Zealand. Partnerships between researchers and practitioners are central to the TLRI. The fund is open to proposals from all education and training agencies, including the early childhood, school, and post-school sectors. The TLRI was established by the government in 2003. This publication focuses particularly on the extent to which the literacy-related projects build a cumulative body of knowledge linking teaching and learning, address themes of strategic importance to education in New Zealand, build upon New Zealand-based research evidence, draw on related international research, and are forward looking.

New Zealand Council for Educational Research, Wellington., Boyd, Sally, McDowall, Sue, and Cooper, Garrick
- Abstract
This report documents the Innovative Pathways study of nonconventional year 12 and 13 programs at 7 schools, considered successful in assisting "at risk" students in their transition from school to the work force or further education and training. Elements of good practice are documented that contributed to and assisted students' decisions regarding transition. These programs gave extra support to students by providing courses tailored to individual interests that were also linked to their career interests, opportunities for students to choose from optional content areas, a focus on the whole student and their personal development and career plans, and partnerships with employers, tertiary trainers, and tertiary institutes. All programs had an emphasis on students gaining qualifications, becoming work-ready, making links to tertiary study, and developing personally. Students viewed the courses as practical, relevant, fun, motivating, and achievable. This information highlights the important role that schools have to play in providing options and information to students, the importance of school-parent communication, and the importance of the range of partnerships that schools have developed. Six appendices contain a student introductory letter and consent form, and student, parent, program-leader, program-teacher, and nonschool-provider interviews. (Contains 56 references, 27 tables, and 2 figures.) (RT)

- Abstract
This report presents the findings from a 2-stage, multi-method study conducted in 2000 and 2001 on the editing skills and processes which students at two schools in New Zealand used when working with word processors and with pencils. The study's main aim was to examine the influence of the use of a word processor on students' editing processes and writing products. In addition, the relationships between the year level, gender, and literacy level of the students in the study, and their editing processes and products were examined. Comparable data were collected from 96 students in Years 3/4, 5, and 7. Data were collected by using interviews and observations, and by analyzing the writing samples of students. Each student was observed completing two tasks--one using a word processor and the other using a pencil. The 21 teachers involved were interviewed about their teaching of writing and editing skills, and the place of word processors in their classroom writing program. Overall, the Year 7 students reported greater school computer use than the Year 5 students, who in turn reported greater use than the Year 3/4 students. In general, students showed high levels of motivation when using a word processor. Apart from spelling differences, there were no significant differences in the overall quality of the writing samples by writing mode. Appended are sample parent and teacher letters, teacher and student interviews and other materials. (Contains 9 tables, 3 figures, and 20 references.) (NKA)

This study described the relations of parents' and teachers' beliefs and attitudes to forms of parents' involvement in children's first two years of primary school. Parents of children in their first year of primary school (age 5) were recruited from 12 classrooms within four schools in New Zealand; 196 families participated in their child's first year, and 124 families continued to participate in their child's second school year. Parents completed the Family-Involvement Questionnaire, New Zealand, and we archivally collected parent-documented children's oral reading homework. Teachers' rated helpfulness of parents' involvement at school (level 2) and parents' rated teacher invitations to be involved and their perceived time and energy (level 1) contributed to school-based involvement in Year 1 in multilevel models, with parents' rated teacher invitations for involvement also found to predict Year 1 home-school communication in regression analyses. Contributors to Year 1 child-parent reading in multilevel models included level 1 predictors of two or more adults in the home and parents' perceived time and energy. Longitudinal analyses suggested both consistency and change in each form of involvement from Year 1 to Year 2, with increases in each form of involvement found to be associated with increases in parents' and/or teachers' views about involvement in Year 2 in cross-sectional time-series analyses. Implications for schools wanting to engage families are that parents' involvement in children's schooling may be influenced by parents' perceptions of their capacity, teachers' engagement efforts, and the school's climate for involvement.

Primary objective: To determine how visible markers of brain injury interact with people's knowledge about brain injury to influence people's attributions for undesirable behaviours of a person with brain injury. Research design, method and procedures: Scenarios in Experiment 1 ( n = 98) and Experiment 2 ( n = 148) described an adolescent pictured with or without a head scar, who showed four behavioural changes. Participants rated two causal attributions for each behaviour: brain injury and adolescence. Experiment 1 varied information that the adolescent had a brain injury and Experiment 2 assessed participants' familiarity with brain injury. Main outcomes and results: The presence of a head scar increased attributions to brain injury. In Experiment 1, participants not informed about the brain injury attributed the behaviours more to adolescence than to brain injury than informed participants. In Experiment 2, in the 'no scar' condition participants familiar with brain injury attributed the behaviours more to brain injury than those who were not. Conclusion: Markers of brain injury interact with people's knowledge about brain injury in shaping people's attributions for the behaviour of persons with brain injury. When people attribute sequelae of the brain injury to other causes, this may hinder appropriate treatment. [ABSTRACT FROM AUTHOR]

RANDOMIZED controlled trials ,PIPERAZINE ,ALCOHOL ,DRUG side effects - Abstract
The objective of this study was to determine the clinical effects of party pills containing benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP) when taken alone and in combination with alcohol. The study was a randomised, double-blind, placebo-controlled trial conducted in a hospital-based clinic in Wellington, New Zealand. Thirty-five volunteers who had previously used party pills containing BZP were included in this trial. Participants received one of the following four treatments: 300 mg/74 mg BZP/TFMPP and placebo, 300 mg/74 mg BZP/TFMPP and 57.6 g (6 units) alcohol, placebo and 57.6 g (6 units) alcohol and double placebo. The primary outcome variable was a measure of driving performance, the standard deviation of lateral position (SDLP) measured at 6.5 h. Secondary measures included adverse events, cardiovascular effects, psychological function and delayed effects on sleep. The study was stopped early, after 35 of the planned 64 subjects had undertaken testing, because of severe adverse events that occurred in four of 10 BZP/TFMPP-only subjects, three of seven combined BZP/TFMPP and alcohol subjects, none of the 6 placebo subjects, and none of the 12 alcohol-only subjects. The overall rate of severe adverse events (defined as causing considerable interference with usual activity and/or rated by subject as severe) in those receiving BZP/TFMPP was seven of 17 (41.2%, 95% CI 18.4-67.1). The severe events included agitation, anxiety, hallucinations, vomiting, insomnia and migraine. BZP/TFMPP significantly improved the driving performance, decreasing SDLP at -4.2 cm (95% CI -6.8 to -1.6, P = 0.002). The effect of alcohol was to increase SDLP: 2.3 cm (95% CI -0.3 to 4.9, P = 0.08). BZP/TFMPP also resulted in increased heart rate and blood pressure and in difficulty in getting to sleep. BZP/TFMPP alone or with alcohol carries a significant risk of severe adverse events when taken in similar doses to those recommended by manufacturers. [ABSTRACT FROM AUTHOR]

BIOGEOGRAPHY , *ANIMALS , *PLATE tectonics - Abstract
Aim To describe New Zealand’s historical terrestrial biogeography and place this history in a wider Southern Hemisphere context. Location New Zealand. Methods The analysis is based primarily on literature on the distributions and relationships of New Zealand’s terrestrial flora and fauna. Results New Zealand is shown to have a biota that has broad relationships, primarily around the cool Southern Hemisphere, as well as with New Caledonia to the north. There are hints of ancient Gondwanan taxa, although the long-argued predominance of taxa derived by vicariant processes, driven by plate tectonics and the fragmentation of Gondwana, is no longer accepted as a principal explanation of the biota’s origins and relationships. Main conclusions Most of the terrestrial New Zealand flora and fauna has clearly arrived in New Zealand much more recently than the postulated separation of New Zealand from Gondwana, dated at c. 80 Ma. There is a view that New Zealand may have disappeared completely beneath the sea in the early Cenozoic, and acceptance of this would mean derivation of the entire biota by transoceanic dispersal. However, there are elements in the biota that seem to have broad distributions that date back to Gondwanan times, and also some that are thought unlikely to have been able to disperse to New Zealand across ocean gaps, especially freshwater organisms. Very strong connections to the biota of Australia, rather than to South America, are inconsistent with the timing of New Zealand’s ancient and early separation from Gondwana and seem likely to have resulted from dispersal.

Galaxiid fishes are commonly assumed to exhibit a Gondwanan distribution, but little fossil evidence has been available to support or refute this assumption until now. Here we report on three species of fossil Galaxias, represented by exquisitely preserved, almost entire skeletons, together with jaw and skull fragments, from several Miocene lacustrine deposits in Otago, South Island, New Zealand. These are the only certain Galaxias fossils, and provide unequivocal evidence that the genus was abundant, and taxonomically and ecologically diverse in the New Zealand region before 23 million years ago. One new species, Galaxias effusus, from an Early Miocene diatomite deposit near Middlemarch is described on the basis of low vertebral count, short caudal peduncle, expansive dorsal, caudal and anal fins, rounded to truncate caudal fin, with 15 principal caudal fin rays. The intact skeletons of G. effusus confirm that they inhabited a deep, stratified maar lake with cool, anoxic bottom water. The maar lake was completely landlocked, from sedimentological evidence, and this species must have been nonmigratory. Disarticulated fish jaws and skull fragments from Early Miocene mudstones near Bannockburn are likely to be from a second large species of Galaxias on the basis of dentary, premaxilla and parasphenoid size and morphology. These disarticulated fish remains from a regionally extensive inland lake system indicate decomposition and/or predation in shallow nearshore environments, but we have no evidence yet of migratory behaviour. New specimens of G. kaikorai Whitley from Late Miocene diatomite deposits near Dunedin confirm its morphological similarity to the living G. brevipinnis. The occurrence and diversity of galaxiids in lakes of early and Late Miocene age in southern New Zealand can be explained by either oceanic dispersal across the Southern Hemisphere at any time during the Cenozoic, relict Gondwanan distributions or, most likely, an ancient Gondwanan origin overprinted by Cenozoic dispersal.

The taxonomic status of Gobiomorphus alpinus Stokell (1962) has recently been questioned. It is a localised endemic in the Tarndale lakes, submontane tarns at c. 1050 m elevation in inland Marlborough, South Island. Suggestions that this species is an ecophenotype of the widespread, amphidromous G. cotidianus McDowall, 1975 are refuted, and we discuss evidence that basing this conclusion on limited molecular data is of dubious worth. More broad-based molecular comparisons, re-examination of meristic and morphometric data, and comparisons of data on the Tarndale bully populations with specimens of G. cotidianus from another high elevation tam, affirm the taxonomic distinctness of G. alpinus. In the absence of appropriate high resolution molecular data (e.g., quantitative trait loci, AFLPs, etc), we conclude that the Tarndale populations warrant taxonomic recognition, and a level of conservation consistent with their range-restricted endemism.

The origin, ecology, and status of New Zealand's freshwater fisheries resources are reviewed. Rivers are the main freshwater features in these Pacific temperate-zone islands. Geological events, the islands' remoteness, and the recent nature of human colonization (first Maori and then European) have shaped the freshwater ichthyofauna. Diadromy is a dominant ecological feature for many indigenous species. Many species have also been introduced to create fisheries. Traditional Maori fisheries are focussed on indigenous eels and whitebait while recreational fisheries target introduced salmonids. Management of New Zealand freshwater fish is dispersed among several departments. New Zealand habitats are pristine by global standards due largely to the recent settlement of European colonists. Many rivers have been impounded for electricity generation; this constitutes the main environmental issue for freshwater fish. Intensification of agriculture also poses a growing eutrophication threat. The ecologies of indigenous species are becoming better known but much knowledge is anecdotal. Efforts to conserve indigenous freshwater species are increasing. Impoundment, irrigation, deforestation, and introduced salmonids, are the main threats to the native fauna. [ABSTRACT FROM AUTHOR]

Several diadromous New Zealand and Australian species of Galaxias are now known, or suspected, to deposit their eggs amongst riparian vegetation or substrates either supratidally in estuaries or in forested streams in locations that are only temporarily submerged by elevated water levels. The eggs develop in a humid atmosphere and hatch when the egg deposition sites are resubmerged; a significant role for agitation in stimulating hatching seeming likely. There are risks from the eggs becoming dehydrated, and also from a failure by water to resubmerge the eggs before they have exhausted their energy resources. Hatching is triggered by elevated flows, perhaps being an outcome of agitation of the eggs. Elevated flows may also increase the rate of downstream transport of the larvae, facilitating survival during dispersal to sea from spawning sites in streams that may be long distances inland. Hatching during flood events may favour survival of the larvae because turbid flows may provide ‘cover’ for the larvae as they emigrate to sea. Risks from egg predation by aquatic predators may be replaced by risks from terrestrial predators. [ABSTRACT FROM AUTHOR]

Fish fossils that appear to be of Gobiomorphus species are described from lake sediments from widely separated localities: near St Bathans, Central Otago, and the Ormond Valley of the Waipaoa River, inland from Gisborne. Dating of the sites suggests that the fishes from Central Otago are Early Miocene in age (c. 20-16 million years old), while those from Ormond Valley are of mid-Pleistocene age (c. 620 000 years).

BIOGEOGRAPHY , *LANDFORMS , *ISLANDS , *GEOLOGY , *PATAGONIANS - Abstract
This paper describes the biogeographical setting of the Falkland Islands, in the context of the relationships of the islands’ biota to other sub-Antarctic/cold temperate lands.The analysis focuses primarily on the Falklands biota, and explores its relationships to those of Patagonian South America and South Africa, other southern lands and the islands of the sub-Antarctic Pacific, Indian and Atlantic Oceans.The study derives largely from literature sources on the biota and geological history of the Falkland Islands.The animals and plants known from the Falkland Islands exhibit strong affinities with those of Patagonian South America, and especially Tierra del Fuego; additional affinities are with various remote islands of the sub-Antarctic, as well as New Zealand and to a lesser extent Australia; often these are shared with Patagonia. While the biotic affinities might be interpreted, by some, as indicating a former Gondwanan/South American geological connection of the Falklands, geological evidence points to the Falklands formerly having a land connection to south-eastern South Africa. Only faint hints of a South African biotic connection remain. The historical biotic and geological connections of the Falklands thus conflict. Moreover, the Falklands biota is so strongly Patagonian that derivation of that biota is best seen as resulting from dispersal, much of it probably recent. This dispersal biota appears to have replaced, and perhaps displaced, the South African biota present on the islands as they detached from South Africa and drifted across the south Atlantic Ocean, as it opened up as South America and Africa drifted apart.

FISH habitats , *FISHERIES , *AQUATIC ecology , *SPECIES diversity , *EXOTIC fishes - Abstract
New Zealand has prolific, cool, clear fresh water of high quality, found in numerous medium to small rivers and streams and low elevation to high country lakes. These waterways carry a highly endemic fish fauna of low diversity (36 indigenous species, 21 exotic species). The indigenous fauna is dominated by Galaxiidae (20 species), whereas the most diverse exotic groups are Salmonidae and Cyprinidae (7 species of each). The steep topography of the country means that the rivers and streams tend to be swiftly flowing, with coarse gravel and cobble, substrates of hard rock, and a high proportion of the indigenous species live within these substrates. About half the indigenous species are diadromous, undertaking regular, seasonally-timed migrations to and from the sea. Fisheries based on the indigenous fauna include modest commercial anguillid eel and galaxiid whitebait fisheries, but probably the chief form of freshwater fisheries exploitation (in overall economic terms) is for New Zealand's world-renowned, recreational angling fisheries for salmonids. Research on the fauna is broadly spread across diverse fields, from studies of the place of freshwater fishes in the community ecology of river and stream biotas as a whole, to focussed studies on habitats of threatened species, design of fish passage facilities for migratory fishes, the effects of introduced exotic species on the indigenous fauna, the impacts of human stream perturbation on aquatic values including fish, and understanding the local ecology of species introduced to New Zealand from other lands.

Cheimarrichthys fosteri is an endemic New Zealand freshwater fish that has its closest common ancestry with the blue cod, Parapercis colias, a species found in New Zealand coastal seas. Cheimarrichthys fosteri is amphidromous, and widely distributed around New Zealand. The fact that it has marine-living juvenile has a strong impact on the species' distribution. Upstream/inland penetration in river systems is substantial, and the torrentfish reaches 700 m elevation and 289 km upstream from the sea. High elevation is typically achieved only at relatively short distances inland, whereas long inland penetration is achieved typically only in low-gradient river systems. The torrentfish is a poor climber, and explicit barriers to upstream migration, such as natural falls and the construction of dams and weirs, limit inland penetration in many river systems. Sparse distribution in some areas, particularly in eastern New Zealand may be due in part to absence or sparseness of riverine gravels. Absence from other areas, such as around Cook and Foveaux straits, the Marlborough Sounds, Fiordland and Stewart and Chatham islands, may result from oceanographic conditions that do not favour return to rivers of the marine-living juveniles. Ecological and behavioural variables relating to the marine life intervals are the predominating factors influencing distribution, and historical biogeographical influences are of minor importance.

ABSTRACT / In general, diadromous (and particularly amphidromous and catadromous) freshwater fishes decline in frequency of occurrence, change age/size structure, and probably also decline in abundance with increasing elevation and distance upstream from the sea. In freshwater fish faunas with a high proportion of migratory species, as in New Zealand, these changes in occurrence and abundance result in a breakdown of the relationship between fish abundance and habitat quality, making application of the index of biotic integrity (IBI) as a measure of habitat quality problematical since the index depends on the relationship between population metrics and habitat quality. An alternative approach applicable to assessing temporal changes in habitat quality and that uses a large database on fish distributions, involves analysis of the distribution of species across their natural distributions. In this paper we generate curves of occurrence of species across ranges of altitude and distance inland and show, through comparisons of data subsets, that the curves are consistent estimators of species' occurrence and therefore useful as indicators of habitat quality.

1. Diadromy is a dominating behavioural characteristic of fish faunas in New Zealand rivers, with amphidromy and catadromy being the most common strategies. 2. Juvenile life stages of amphidromous and catadromous species migrate from the sea, through river systems, to find habitats for feeding, growth, maturation and reproduction. 3. Studies of fish distributions in rivers of the West Coast of the South Island of New Zealand show that, in most species, these migrations result in more or less continuous distributions from the lower reaches to the upstream limits of each species’ range. 4. Upstream penetration of rivers varies widely between species and this generates downstream–upstream trajectories of declining species richness. 5. Parallel trajectories of declining downstream–upstream abundance are likely in each species. 6. These patterns demonstrate the presence of downstream–upstream linkages in the community ecology of freshwater fishes in New Zealand rivers. [ABSTRACT FROM AUTHOR]
