Influence of aquatic macrophyte habitat complexity on invertebrate abundance and richness in tropical lagoons
TLDR
These results indicate that habitat complexity provided by the different architectures of aquatic plants, significantly affects both S and total N, and suggest that measurements of structural complexity, measured through fractal geometry, should be included in studies aimed at explaining attributes of attached invertebrates at small scales.

Variation in ostracod (Crustacea, Ostracoda) communities in the alluvial valley of the upper Paraná River (Brazil) in relation to substrate
TLDR
Investigating the variation in ostracod (small, bivalved crustaceans) communities in relation to substrates and related environmental variables in Brazil found uniformity in abiotic factors, which might be owing to the occurrence of large flooding events, unites all water bodies, even those that are generally separated.

Does the habitat structure control the distribution and diversity of the Odonatofauna?
TLDR
This work assumed the hypothesis of habitat heterogeneity, that is, the higher habitat complexity leads to greater diversity of Odonata, and analyzed the influence of habitat structure on the distribution of this community, and the effects of abiotic variables.

Description of a new genus and species of Candonopsini (Crustacea, Ostracoda, Candoninae) from the alluvial valley of the Upper Parana River (Brazil, South America)
TLDR
A new candonid genus is described, with C. rochai gen. nov. as type species, from the alluvial valley of the Upper Parana River, which differs markedly from Latinopsis in the size and shape of the calcified inner lamellae of both valves and in the type of hemipenis.

Pleuston communities are buffered from regional flood pulses: the example of ostracods in the Paraná River floodplain, Brazil
Summary 1. It is widely acknowledged that sudden, large-scale flood pulses are drivers of benthic and planktonic biodiversity change in floodplains. The impact of such pulses on pleuston (biotic…

On a new cypridopsine genus (Crustacea, Ostracoda, Cyprididae) from the Upper Paraná River Floodplain (Brazil)
We describe a new genus, Cabelodopsis n. gen., for the South American ostracod species Cypridopsella hispida Sars, 1901. Zonocypris G.W. Muller, 1898 and Cabelodopsis n. gen. are together united in…

Effect of land use on the composition, diversity and abundance of insects drifting in neotropical streams.
TLDR
The species composition can be considered as the best predictor of impacts on the drifting insect community, due to the replacement of specialist species by generalist species in the urban stream.

Body-size shifts in aquatic and terrestrial urban communities
TLDR
It is demonstrated that urban communities generally consist of smaller species, and that the general trend towards smaller-sized species is overruled by filtering for larger species when there is positive covariation between size and dispersal, which can mitigate the low connectivity of ecological resources in urban settings.

Ostracod (Crustacea) colonization of a native and a non-native macrophyte species of Hydrocharitaceae in the Upper Paraná floodplain (Brazil): an experimental evaluation
TLDR
The results show that H. verticillata might provide favorable habitats for native ostracod assemblages, and cumulative curves, which permit to eliminate effects of abundance on richness, indicated a significantly higher number of ostracOD species on H.–verticilata.

Diet and feeding selectivity of a benthivorous fish in streams: responses to the effects of urbanization.
TLDR
The results indicate that trophic studies of benthivorous fishes, such as I. mirini, may represent an alternative way to assess human effects on streams and that environmental conditions influenced the diet and prey selection of this species in response to the differences in diversity and abundance of the food organisms.
