Influence of environmental features at multiple scales and spatial structure on stream fish communities in a tropical agricultural region
(Taylor & Francis Inc, 2017-01-01)
Land cover change for agricultural expansion exerts strong pressures on tropical streams. We examined the relative contributions of catchment land cover, local environmental features, and spatial patterns on stream fish ...
Neotropical fish-fruit interactions: eco-evolutionary dynamics and conservation
(Wiley-Blackwell, 2015-11-01)
Frugivorous fish play a prominent role in seed dispersal and reproductive dynamics of plant communities in riparian and floodplain habitats of tropical regions worldwide. In Neotropical wetlands, many plant species have ...
Fish assemblage structure in a Neotropical urbanised prairie stream exposed to multiple natural and anthropic factors
(Wiley Blackwell Publishing, Inc, 2021-07)
A myriad of factors affect stream fish assemblages, and most of them are intimately regulated by surrounding land uses. One of the most pernicious impacts on streams is the release of urban effluents. Accordingly, understanding ...
Associations between fish assemblage and riparian vegetation in the Corumbataí River Basin (SP)
(Instituto Internacional de Ecologia, 2007-05-01)
Este trabalho teve o objetivo de examinar se existem associações entre as espécies de peixes e o estado de conservação das matas ciliares na bacia do rio Corumbataí. Foram escolhidos 4 rios principais com 3 pontos de coleta ...

Edge-mediated effects of forest fragments on the trophic structure of stream fish
(2015-12-01)
The aquatic communities of headwater streams are highly influenced by the surrounding matrix. The edge effects of forest fragments are known to influence terrestrial communities; however, their influence on aquatic communities ...
Identification of key microhabitats for fish assemblages in tropical Brazilian savanna streams
(Wiley-Blackwell, 2012-12-01)
The habitat use by stream fish can provide an understanding of this important component of species niches, and the changes in the availability of certain structures of instream habitats have a strong influence on the ...
Grass-dominated stream sites exhibit low fish species diversity and dominance by guppies: an assessment of two tropical pasture river basins
(Springer, 2009-10-01)
This study investigates whether (1) structural configuration (considering substrate composition, wood debris, marginal and riparian vegetation) of streams suggests habitat simplification on a basin scale and (2) fish ...
