Abstract

Freshwater fish metacommunities are best understood when considering the dendritic structure of riverine networks. The dendritic structure imposes restrictions to dispersal associated with the connectivity. Many structures restrict the movement of fish even more, such as dams and the terrain slope (dispersal costs). We investigated the influence of environmental predictors and dispersal costs on the beta diversity of freshwater fishes from the Upper Tennessee River using Generalised Dissimilarity Modelling (GDM). In addition, we tested the effects of asymmetrical dispersal costs (high costs for upstream dispersal) on the nestedness of native and non‐native fishes. Environmental predictors were more important than dispersal costs for explaining the overall fish dissimilarity in the GDM models, with the turnover capturing most of the explanation compared to the species richness difference. Dam heights were the most important dispersal cost variable in the GDM, mainly for species turnover. Overall dissimilarity of the native fish subset was better explained by environmental and dispersal variables than non‐native fish (20.03% vs. 8.41%). Considering the native species assemblage subset, dispersal cost related to maximum channel slope between pairs of sites and watercourse distance increased the nestedness of adjacent upstream–downstream sites, whereas those attributed to dams reduced the nestedness. The results support that dams increase overall dissimilarity in the native fish metacommunity of the Upper Tennessee basin, but also reduce the nestedness of adjacent sites. Our findings improve the knowledge on how mechanisms and processes associated with dispersal costs in watersheds under the effects of dams create patterns of dissimilarity and nestedness.

13. Living on a catfish: nested occupation of ectosymbiotic chironomids on host body

Abstract

Symbiotic species often have preferential attachment sites on their host body and thus some sites may only be occupied if the supposed best sites are already occupied. Alternatively, colonization may be similar in all sites, but removal may differ among them. Both mechanisms might generate a nested pattern. Moreover, the host size can alter the quality of the site for symbiotic occupation; for instance, by increasing the area and anchorage structures or reducing removal. We predicted that the spatial distribution of the ectosymbiotic chironomid Ichthyocladius lilianae Mendes, Andersen and Saether, 2004 on their host, the armored catfish Pareiorhaphis hypselurus (Pereira and Reis, 2002), would present a nested pattern with regards to body-part preference and variation according to host size. We found that (i) suboptimal sites on the host body were usually only occupied by a symbiont when the optimal sites were already occupied and (ii) sites occupied by larvae on small host body surface were a subset of the sites occupied on large hosts. Our results indicate a nested distribution, yet the mechanisms generating this pattern are unclear. One possibility is that symbionts have preferential sites for attachment on the host body surface and compete for these sites. As an alternative, symbionts may present no preference and colonize equally all sites, but they remain attached to sites that offer better resources or protection from removal. Key words: fish, Ichthyocladius lilianae, interspecific interaction, Chironomidae, midge larvae, NODF, Pareiorhaphis hypselurus. Les espèces vivant en symbiose ont souvent des sites de fixation privilégiés sur le corps de leur hôte, de sorte que certains sites peuvent n'être occupés que si les meilleurs sites présumés sont déjà occupés. Ou encore, la colonisation pourrait être semblable dans tous les sites, mais l'enlèvement pourrait varier entre eux. Ces deux mécanismes peuvent produire un motif emboîté. En outre, la taille de l'hôte peut se traduire par des variations de la qualité des sites pour l'occupation de symbiontes, en augmentant, par exemple, la superficie et les structures d'ancrage ou en réduisant l'enlèvement. Nous avons prédit que la répartition spatiale de symbiontes chironomidés Ichthyocladius lilianae Mendes, Andersen et Sæther, 2004, sur l'hôte qu'est le poisson-chat blindé (Pareiorhaphis hypselurus (Pereira et Reis, 2002)) présenterait un motif emboîté en ce qui concerne la préférence pour différentes parties du corps et ses variations selon la taille de l'hôte. Nous avons constaté que (i) les sites moins qu'optimaux sur le corps de l'hôte ne sont habituellement occupés par un symbionte que lorsque les sites optimaux sont déjà occupés et (ii) les sites occupés par les larves sur la surface du corps de petits hôtes sont un sous-ensemble des sites occupés sur les grands hôtes. Si nos résultats indiquent une répartition emboîtée, les mécanismes qui produisent cette répartition ne sont pas clairs. Une possibilité serait que les symbiontes ont des sites de fixation préférés sur la surface du corps de l'hôte et qu'ils sont en concurrence pour ces sites. Ou encore, les symbiontes pourraient ne pas avoir de préférence et coloniser de manière uniforme tous les sites, mais demeurer fixés aux sites qui offrent de meilleures ressources ou une meilleure protection contre l'enlèvement.

Abstract

Motivation: Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment and freshwater ecosystem health, as well as to test ecological hypotheses. Despite their importance, a comprehensive, global database of aquatic insect occurrences for mapping freshwater biodiversity in macroecological studies and applied freshwater research is missing. We aim to fill this gap and present the Global EPTO Database, which includes worldwide geo‐referenced aquatic insect occurrence records for four major taxa groups: Ephemeroptera, Plecoptera, Trichoptera and Odonata (EPTO). Main type of variables contained: A total of 8,368,467 occurrence records globally, of which 8,319,689 (99%) are publicly available. The records are attributed to the corresponding drainage basin and sub‐catchment based on the Hydrography90m dataset and are accompanied by the elevation value, the freshwater ecoregion and the protection status of their location. Spatial location and grain: The database covers the global extent, with 86% of the observation records having coordinates with at least four decimal digits (11.1 m precision at the equator) in the World Geodetic System 1984 (WGS84) coordinate reference system. Time period and grain: Sampling years span from 1951 to 2021. Ninety‐nine percent of the records have information on the year of the observation, 95% on the year and month, while 94% have a complete date. In the case of seven sub‐datasets, exact dates can be retrieved upon communication with the data contributors. Major taxa and level of measurement: Ephemeroptera, Plecoptera, Trichoptera and Odonata, standardized at the genus taxonomic level. We provide species names for 7,727,980 (93%) records without further taxonomic verification. Software format: The entire tab‐separated value (.csv) database can be downloaded and visualized at https://glowabio.org/project/epto_database/. Fifty individual datasets are also available at htt

27. Respondents to survey from Insect decline in Brazil: an appraisal of current evidence

Author

Lewinsohn, Thomas M., Agostini, Kayna, Lucci Freitas, André Victor, and Melo, Adriano S.

Abstract

Recent reviews of data on worldwide insect decline include almost no information on Brazil. We gathered evidence from the literature searches and a survey sent to researchers, to which 96 replied and 56 provided information and publications. We present 75 instances of trends recorded over an average span of 11 years for aquatic and 22 years for terrestrial insects. These include time-replicated samples and expert opinion based on long-term local collections. Most terrestrial data are for butterflies, bees and scarab beetles. Aquatic studies include several insect orders, usually sorted to genus or family. Terrestrial insects showed significantly more cases of declines than increases, both in abundance (17 : 3) and in diversity (11 : 1). In aquatic cases, no tendency was detected in abundance (2 : 2) or diversity (3 : 4), not counting cases with no trend. Differences of these results among habitats may be due to the shorter span and less change in environmental conditions in the aquatic surveys, which included sites already degraded before sampling. We offer guidelines for future long-term assessments, including resampling of legacy collection sites.
