The environmental heterogeneity of the biotopes that compound the mosaic of the rivers is
essential for the development of the initial stages of fish life. In this sense, we evaluated the …

Fish reproduction in natural environments tends to occur in conditions, including extreme pH
values, ideal for the survival of offspring. In this context, the purpose of this study was to …

By promoting the biological recruitment of relevant natural resources, wetlands offer a major
ecosystem service. This study investigates the importance of wetland habitats of the central …

We investigated spatial and temporal variations in the distribution of fish eggs and larvae in
the Guareí River, a free-flowing tributary located in the upper section of the Jurumirim …

The aim of the present study was to verify the use of the arms of the Itaipu Reservoir as
areas of initial development for migratory fish species and to assess the relationship …

We assessed the importance of different types of riverine environments (river channels,
tributaries, and floodplain lagoons) for the early development of fish larvae from different …

In the upper Paraná River floodplain, the populations of Salminus brasiliensis have been
subjected to several anthropic impacts, such as overfishing, the blocking of migratory routes …

Spatial heterogeneity is one of the major sources of compositional dissimilarity among fish in
different biotopes. The availability and distribution of refuge, food, and habitats for breeding …

The objective of this study was to use larval density data to investigate the temporal
reproductive pattern and use of different biotopes of the Paraná River as areas of …

Reproduction is one of the most important biological aspects for the maintenance of viable
populations, and understanding the spatial and seasonal patterns in the reproduction of …
