The article focuses on an ecological study regarding the coastal zonation of Southern Australian coasts in relation to a generalized scheme of classification put forward by ecologist T. A. Stephenson. It mentions that the generalized scheme is not satisfactorily applicable to Southern Australian coasts and a modified scheme is being proposed. It states that the new scheme is an integration of terms and zones which appear most applicable to Australian conditions. It informs that the general applicability of the new scheme of intertidal zonation to coasts other than Southern Australia must be critically examined on the basis of their topography and habitat conditions.

A conference paper about the biological control of Chondrilla juncea is presented. It presents the results of the detailed ecological study being made on C. juncea and the organisms attacking it in Mediterranean Europe, as a prelude to biological control introductions into Australia. Using a line transect method at the dense Chondrilla sites between Barcelona, Spain and Nice, France, observations have shown that the plant populations decline to a greater or lesser extent according to conditions.

The article examines a range of soil chemical data over a variety of climates and parent rocks in north-eastern Australia and within an area of uniform climate and physical substrate on Fraser Island to determine the relevance of these data in the differentiation of forest types. It presents an investigation of the ecological role of soil chemical properties. It aims to evaluate the relative importance of soil physical and chemical factors under defined ecological conditions. The article argues that for the development of intensive management of the forests along the eastern Australian coast, it is of considerable interest for foresters to know the extent to which simple measurements of edaphic factors can predict forest site potential.

The article presents a discussion about the Australian species in Tasmania. The article provides geographical knowledge of the distribution of some Australian plants and animals which are said to be belt-forming and intertidal. It explores the literature and nomenclature to decribe the ecology of such species. Also, it defines Ecklonia radiata, Phyllospora comosa, Hormosira banksii, sarcophycus potatorum, pyura, stolonifera, serpulid, barnacles, and other species found in Tasmania. The article is supplemented with details on their habitats and their interaction.

The article reports on the demographic treatment of density data for Danthonia cespitosa Gaudich and Chloris acicularis Lindl, two indigenous perennial grasses of differing ecological status in cropped and protected semi-arid grassland in New South Wales, Australia. It also mentions the difference in phenology between the two grasses, Danthonia cespitosa being an opportunist in its vegetative growth and responding to rain in all seasons, while Chloris acicularis is inactive in winter and depends on effective summer rain for both vegetative and reproductive growth.

The article presents a synecological study of rainforest vegetation in eastern Australia. It examines the ecological significance of some soil physical properties by using them as attributes in numerical analysis, and then examining the relation of the resulting soil groupings to floristic and structural types of forest vegetation. It aims to evaluate the relative importance of soil physical and chemical factors under defined ecological conditions. The study findings suggest that the relationship between the chemical composition of the soil parent material and the physical properties and mineral status of the soils supporting complex rainforests suggests that such forests require, not only adequate water, but also good aeration and high amounts of plant nutrients.

The article examines the characteristics of the deserts of Western Australia. It aims to determine where the boundaries of these deserts lie and in what way they are distinguished from one another and from other parts of Western Australia not popularly considered to be desert. It also presents a historical review of the exploration of this area, given down to the botanical exploration of the past 7 years. The article concludes with some discussion of the potential for economic use of this area and of the growth forms of Australian desert plants.

This article presents a study which investigated the plant patterns of different seasons in two stands of mallee vegetation in Australia. A brief background on the study areas, a review of previous related literature and a description of the study's methodology are provided. The study found that mallee vegetation is dominated by tall shrubby individuals of Eucalyptus and in many areas it can be divided into mallee thickets and large openings. The phytosociological patterns of stands based on seasons are explored.

The article offers a research on mangrove swamp and salt marsh communities of the Sydney district. The research aims to explain the wide variation in distinctiveness of zonation of the dominant plant species occurring in the mangrove swamps and salt marsh communities of the district. It describes the variation in vegetation pattern and species composition between different localities. It also presents details of soil profile characteristics, particle size distribution, loss on ignition, field moisture content, bulk density, cation exchange capacity, infiltration by water and pH.

The presents a study related to pattern analysis exhibited by growing colonizing species on several habitats from north-west Iceland and southern and central Australia. It was conducted on plant communities in these areas, and results of pattern analyses were presented from communities of colonizing species. According to the author, discovered patterns in the environment from the pattern analysis drew attention to the different scales and intensities. However, he argues that these factors cannot be accepted as the only evidence of relative stability.

The article presents a physiognomic vegetation map of Australia. The author mentions several incomplete vegetation maps of the continent. The author contends that a useful vegetation map is one that is capable of widespread use and one based on a classification that enables specialists, outside plant taxonomy and ecology, to recognize vegetation characteristics and environmental relationships and to be able to make comparisons. It states that the recent comprehensive analyses of the methodology of plant geography demonstrates the increasing awareness of the significance of structure in vegetation classification.

The article describes the effects of rabbit grazing on the grasslands of Macquarie Island, located mid-way between New Zealand and Antarctica. The two widespread dominant species in the grasslands are the Poa foliosa and Stilbocarpa polaris, while the Polystichum vestitum and Poa hamiltoni are the co-dominants that are not widely developed. The article states that the effects of rabbits are due to the selective grazing of only the most number of species. In addition, remote plant communities consisting of few species are likely to be susceptible to rabbit invasion.

The article presents a study which examines the effect of oceanographical and physical factors on the distribution of belt-forming species and on some of the more common non-belt-forming species on rocky shores of the East Australian coast The physical environment on the eastern Australian coast is described in detail, with particular reference being made to ocean currents and sea temperatures. The distribution of the most important intertidal species on the eastern coast of Australia is examined and the biogeographic provinces are also noted.

The article presents the classification of the Australian Rain forests. Information includes Australian rain forests' three formations like Tropical, Subtropical and Temperate. It mentions that the 12 classifications of rain forest formations are based on its physiognomic and structural features, such as leaf size, tree layers, emergents and the presence of special life forms, such as woody lianes and mossy epiphytes. Explanation on the diagnostic characters used in the classification is also discussed, including their significance.

The article discusses the criticism of H. B. S. Womersley and J. S. Edmonds on the idea used by T. A. Stephenson and A. Stephenson in the study on marine coastal zonation in Australia. The Stephensons suggested a general scheme for the zonation of marine organisms on rocky coasts, which Womersley and Edmonds think is not applicable since the scheme does not employ satisfactorily to southern Australian seashores. Moreover, they argue that a general scheme of coastal zonation must be relevant to any type of coast, hence, Stephensons' scheme was formulated for rocky coasts, should not be enforced to all types of coastal formations.

The article presents a discussion on a study about zonation between tide-marks on rocky coasts in various regions and areas including England, Scotland, the Indian Ocean and the Great Barrier Reef of Australia. Plants and animals also live in these zones between tide-marks. On the British coasts, there were three possible types of zonation observed, namely the littorina zone, the balanoid zone and the laminarian zone. Plants and animals found in these zones include small snails, lichens, barnacles and brown algae.

The article presents a study that evaluates the effect of soil temperature during forest fires in the survivability of vegetation in Australia. The study was administered by measuring and analyzing the implications of soil temperature using a small tube which contains organic compounds and placing it under the ground with one inch deep and experience constant burning for more than eight hours. The study reveals that fires are not capable of killing the vegetation and does not provide any effect on the physical properties of the soil because of its water content that lessen the heat conductivity, in addition, some vegetation are capable of regenerating itself as well as resist high temperature.

The article presents a discussion on the vegetation of grass verges and explores the grass habitats which are regarded as excessively trodden places. It is implied that a considerable degree of similarity exist between the vegetation of the trampled grass verge found on highways and that of the grassy footpath or the sheep track situated whether on lowlands or at high elevation. The article is supplemented with details regarding the botanical composition of the plant communities, ecological distribution, climatic and edaphic backgrounds, and observations drawn from investigating samples coming from Great Britain, Australia, and New Zealand.

The article discusses the physiology of xerophytic plants in Australia. It cites a study which has shown that succulent plants have a low intensity of transpiration while hard-leaved xerophytes and those xerophytes with semi-succulent leaves transpired more than mesophytic leaves under high tension of meteorological factors. In addition, the study found that plants subjected to permanent wilting possess a greater number of stomata per unit area than those that develop in an unwilted condition. Data on stomatal size and stomatal index are also provided.
