A dataset of individual wet weights of benthic macroinvertebrates
Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common

Condições de divisão e regeneração em Naididas
A posição da zona de divisão nos Oligoquetos paratômicos varia dentro da mesma população. Dos resultados obtidos pelos autores anteriores e das minhas experiências e observações depreende-se ser o n (o número dos segmentos precedentes à zona de divisão) influenciado por várias condições externas, assim como por certos fatores internos.

Macroinvertebrates associated with bryophyta in a first-order Atlantic Forest stream
This study describes the composition and structure of the benthic community associated with bryophytes in a first-order stream, located in a biological reserve of the Atlantic Forest, during two seasons.

ABSTRACT Freshwater mussels are a globally threatened taxon, but little is known about population trajectories for species outside Europe and North America. To contribute to understanding of mussel conservation status outside these regions, we surveyed mussel and other invertebrate populations in waterbodies across Dhaka, Bangladesh, to assess ...

Environmental warming increases the importance of high‐turnover energy channels in stream food webs
Abstract Warming temperatures are altering communities and trophic networks across Earth's ecosystems. While the overall influence of warming on food webs is often context‐dependent, increasing temperatures are predicted to change communities in two fundamental ways: (1) by reducing average body size and (2) by increasing individual metabolic rates ...

Abstract Ecological speciation within the mormyrid genus Campylomormyrus resulted in sympatric species exhibiting divergence in their feeding apparatus and electric organ discharge (EOD). This study documents the overall diet of the genus Campylomormyrus and examines the hypothesis that the Campylomormyrus radiation is caused by adaptation to different
