Impacts of climate warming on lake fish community structure and potential effects on ecosystem function
Fish play a key role in the trophic dynamics of lakes, not least in shallow systems. With climate warming, complex changes in fish community structure may be expected owing to the direct and indirectExpand
Climate change impacts on lakes: an integrated ecological perspective based on a multi-faceted approach, with special focus on shallow lakes
Freshwater ecosystems and their biodiversity are presently seriously threatened by global development and population growth, leading to increases in nutrient inputs and intensification ofExpand
Length–weight relationships of eight fish species from the lower section of the Uruguay River (Río Negro, Uruguay)
This study reports length–weight relationships for Apareiodon affinis, Leporinus obtusidens, Cynopotamus argenteus, Loricariichthys melanocheilus, Parapimelodus valenciennis, Rhinodoras dorbignyi and Pachyurus bonariensis and provides the new maximum size for three species. Expand
Different responses of functional traits and diversity of stream macroinvertebrates to environmental and spatial factors in the Xishuangbanna watershed of the upper Mekong River Basin, China.
The results confirm the dominant role of environmental variables in the determination of community trait composition and functional diversity, and substantiate the contribution of spatial vectors in explaining the variance of functional traits and diversity. Expand
Meta-analysis Shows a Consistent and Strong Latitudinal Pattern in Fish Omnivory Across Ecosystems
It is hypothesized that this macroecological pattern in fish trophic structure is, in part, explained by the higher total fish diversity at lower latitudes and by the effect of temperature on individual food intake rates; both factors ultimately increasing animal food limitation as the systems get warmer.

Fish assemblage changes along a trophic gradient induced by agricultural activities (Santa Lucía, Uruguay)
This study analyzed the fish composition, diversity and evenness in fourteen reaches, of low stream orders within a basin with differing land use intensity, which enabled us to group the fish species according to their specific tolerance to eutrophication. Expand
Length–weight relationships of 26 fish species from the middle section of the Negro River (Tacuarembó‐Durazno, Uruguay)
This study represents the first reference on length–weight relationships for 17 species, and also provides new maximum sizes for eight species. Expand
A new species of Gymnogeophagus Miranda Ribeiro from Uruguay (Teleostei: Cichliformes)
The new species can be distinguished from the remaining substrate-brooding species in the genus by the unique pigmentation of the dorsal fin which consists of light blue, diagonal stripes over a red background in the spiny section and a combination of round, elliptic, and elongated bright blue spots over ared Background in the soft section.

Small birds, big effects: the little auk (Alle alle) transforms high Arctic ecosystems
It is demonstrated that the little auk acts as an ecosystem engineer, transforming ecosystems across a vast region of Northwest Greenland, based on elevated δ15N in MDN, which fuels more than 85% of terrestrial and aquatic biomass in bird influenced systems. Expand
Interacting effects of climate and agriculture on fluvial DOM in temperate and subtropical catchments
Dissolved organic matter (DOM) is an important factor in aquatic ecosystems, which is involved in a large variety of biogeochemical and ecological processes, and recent literature suggests that itExpand
