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 ...
Associações de espécies de peixes em ambientes lóticos da bacia do rio Iguatemi, Estado do Mato Grosso do Sul
(2003-07-01)
The aim of this paper is to describe the patterns of associations between fish species and their distribution in lotic habitats at basin level. Samples were accomplished in 27 localities of Iguatemi river basin, distributed ...
Identification key for fishes from coastal streams of the Atlantic forest of southeastern Brazil
(Revista Biota Neotropica, 2017-01-01)
In recent decades, current knowledge about fish from Neotropical streams has greatly increased, but is still deficient. Here we present an identification key for fishes from coastal freshwater streams from a large conservation ...
Canopy cover as the key factor for occurrence and species richness of subtropical stream green algae (Chlorophyta)
(2017-01-01)
Understanding how local and regional environmental factors influence species richness remains a key issue in ecology. Green algae (Chlorophyta) are a diverse and widely occurring group, which may be a good model for studying ...
Organização das assembléias de peixes em riachos da bacia do rio Iguatemi, Estado do Mato Grosso do Sul
(2005-04-01)
Aiming to describe the patterns of the fish assemblages organization in streams of the Iguatemi River basin we sampled streams with seine nets and sieves from November/1999 to August/2000. We collected 567 individuals ...
Stream fish ecology from a landscape ecology perspectiveA ecologia de peixes de riacho sob a perspectiva da ecologia de paisagens
(2021-01-01)
Landscape ecology emphasizes the interaction between spatial patterns and ecological processes, i.e., the consequences of spatial heterogeneity across various scales. It is an interdisciplinary science that seeks to ...
Establishing habitat-specific indicator species in Tierra del Fuego with freshwater macroinvertebrates
(Taylor & Francis, 2018-01)
As a tool to understand Tierra del Fuego’s basic ecology and detect changes due to human pressures, this study develops habitat bioindicators. We compared the freshwater benthic macroinvertebrates at 61 study sites in six ...
Climate change and alpine stream biology: progress, challenges, and opportunities for the future

Ecological distribution of stream macroalgae in different spatial scales using taxonomic and morphological groups
(2012-01-01)
We examined the ecological distribution of macroalgal communities in streams using species groups (taxonomic units = algal phyla, and morphological = morphological types) with similar structures and functions instead of ...

(Sociedade Botânica de São Paulo, 2012-01-01)
We examined the ecological distribution of macroalgal communities in streams using species groups (taxonomic units = algal phyla, and morphological = morphological types) with similar structures and functions instead of ...
