A multiple hypothesis approach to explain species richness patterns in neotropi...
Vieira, Thiago Bernardi; Pavanelli, Carla Simone; Casatti, Lilian; Smith, Welber Senteio; Benedito, Evanilde; Mazzoni, RosanaSeveral hypotheses are used to explain species richness patterns. Some of them (e.g. species-area, species-energy, environment-energy, water-energy, terrestrial primary productivity, environmental spatial heterogeneity, and climatic heterogeneity) are known to explain species richness patterns of terrestrial organisms, especially when they are combined. For aquatic organisms, however, it is unclear if these hyp...
Large-scale Degradation of the Tocantins-Araguaia River Basin
Pelicice, Fernando Mayer; Agostinho, Angelo Antonio; Akama, Alberto; Andrade Filho, José Dilermando; Azevedo-Santos, Valter M. [UNESP]Made available in DSpace on 2022-04-28T19:42:34Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-10-01; The Tocantins-Araguaia Basin is one of the largest river systems in South America, located entirely within Brazilian territory. In the last decades, capital-concentrating activities such as agribusiness, mining, and hydropower promoted extensive changes in land cover, hydrology, and environmental condit...
The ichthyofauna of the Rio Carinhanha basin, one of the main tributaries of th...
Salvador, Gilberto Nepomuceno; Casarim, Ruanny; Rosa, Gustavo Ribeiro; Caldeira, Yuri Malta; Pompeu, Paulo SantosThe ichthyofauna of the Rio São Francisco basin is relatively well-documented. However, most of this knowledge is concentrated at the upper stretch of its catchment area. In this study, we compile a list of species encompassing almost the entire length of the Rio Carinhanha, an important tributary from upper-middle section of the Rio São Francisco, including a comprehensive diversity of environments. A total of...
Stream fish metacommunity organisation across a Neotropical ecoregion: The role...
Borges, Pedro Paulino; Dias, Murilo Sversut; Carvalho, Fernando Rogério; Casatti, Lilian [UNESP]; Pompeu, Paulo Santos; Cetra, MauricioMade available in DSpace on 2020-12-12T02:42:33Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-05-01; Understanding how assemblages are structured in space and the factors promoting their distributions is one of the main goals in Ecology, however, studies regarding the distribution of organisms at larger scales remain biased towards terrestrial groups. We attempt to understand if the structure of stream...

Habitat structure determining the spatial distribution of ichthyofauna in a Bra...
Carvalho, Débora Reis de; Casarim, Ruanny; Pereira, Rafaela Bastos; Pompeu, Paulo SantosThis work aimed to evaluate the relationship between parameters of fish communities and the habitat structure of a stream. Twenty three stretches six meters long were evaluated in the Samambaia stream located inside the Sumidouro Park, Rio das Velhas basin, state of Minas Gerais, Brazil. Fish samplings and habitat characterization were made for each stretch. Seven variables of habitat (vegetal cover, width, dep...
