Importance of local and landscape variables on multiple facets of stream fish biodiversity in a Neotropical agroecosystem
(2020-01-01)
Few studies have considered the effects of environmental variables at different spatial scales on Neotropical stream biodiversity. Furthermore, scale-related studies mostly include only one facet of biodiversity. To determine ...
Responses of aquatic food webs to the addition of structural complexity and basal resource diversity in degraded Neotropical streams
(2017-12-01)
The loss of riparian forests can disrupt the structure and function of lotic ecosystems through increased habitat homogenization and decreased resource diversity. We conducted a field experiment and manipulated structural ...
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 ...
Short-term response of fish assemblages to instream habitat restoration in heavily impacted streams
(2020-01-01)
Habitat homogenization has been a major impact in stream ecosystems, and it is considered one of the main drivers of biotic homogenization as well, leading to the loss of water quality and fish diversity. In this study, ...
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 ...
Mechanism of payments for hydrological ecosystem services in the watershed of the Piray Miní stream
(Universidad Nacional de Misiones. Facultad de Ciencias Económicas. Programa de Posgrado en Administración, 2021-09-28)
To promote the conservation and forest hydrological restoration of the ecosystems located in the watershed of the Piray Miní stream, which supplies water to Eldorado, economic compensation mechanisms are required for the ...
The effects of land use at different spatial scales on instream features in agricultural streams
(2017-07-01)
The conversion of forests into agriculture has been identified as a key process for stream homogenization. However, the effects of this conversion can be scale-dependent. In this context, our aim was to identify the influence ...
Efeitos de florestas ripárias em restauração em ecossistemas de riachos tropicais numa paisagem agrícola
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciências Ambientais - PPGCAmCâmpus São Carlos, 2017-02-15)
The conversion of natural areas to human activities in watersheds is the main cause of riparian forest degradation, which, consequently, decreases the integrity of aquatic ecosystems. Therefore, restoration of riparian ...
Identification of key microhabitats for fish assemblages in tropical Brazilian savanna streams
(Wiley-Blackwell, 2014)
Efeitos de florestas ripárias em restauração na estrutura de comunidades de macroinvertebrados aquáticos e nas taxas de decomposição de matéria orgânica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciências Ambientais - PPGCAmCâmpus São Carlos, 2018-08-03)
Riparian forests play a very important role in protecting watercourses and represent an energy source for the aquatic communities in low-order streams. Therefore, the input of allochthonous material from these ecosystems ...
