How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The COVID‐19 pandemic has heavily impacted academics’ professional and personal lives, forcing many research groups (labs) to shift from an academic system primarily based on in‐person work to an almost full‐time remote workforce during lockdowns. Labs are generally characterized by a strong lab culture that underpins all research and social activi...
Animals can act as sources or sinks of nutrients in ecosystems, and their role in this context may depend on the fate of nutrients in decomposing carcasses, which may contain recalcitrant structures such as bones. Our goal was to assess whether a fish population with high biomass is a source or sink of nutrients to the pelagic zone of a eutrophic l...
Lakes and reservoirs present contrasting differences regarding origin, age and trophic state that may influence their biological communities. In the face of the inevitably rising number of reservoirs worldwide, our objective was to investigate the differences in zooplankton community structure and diversity patterns from 98 tropical shallow lakes a...
The introduction of nonnative species is one of the main threats to freshwater ecosystems. Although omnivory and intraguild predation are common in those systems, little is known about the effects of introduced omnivorous fish on pelagic and littoral communities. This study tested predictions of food-web theory regarding the effects of omnivorous f...
The role of tropical lakes and reservoirs in the global carbon cycle has received increasing attention in the past decade, but our understanding of its variability is still limited. The metabolism of tropical systems may differ profoundly from temperate systems due to the higher temperatures and wider variations in precipitation. Here, we investiga...
Recent studies from temperate lakes indicate that eutrophic systems tend to emit less carbon dioxide (CO2) and bury more organic carbon (OC) than oligotrophic ones, rendering them CO2 sinks in some cases. However, the scarcity of data from tropical systems is critical for a complete understanding of the interplay between eutrophication and aquatic...
Spatial patterns in the abundance of species are determined by local abiotic and biotic conditions, and by the movement of individuals among localities. For species distributed among discrete habitat ‘‘islands’’, such as zooplankton distributed among lakes, local conditions within lakes often dominate low movement rates among lakes to determine the...
