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...
Integrating economic costs and biological traits into global conservation prior...
Loyola, Rafael Dias; Santos, Luiz Gustavo Rodrigues Oliveira; Almeida Neto, Mário; Nogueira, Denise Martins; Kubota, UmbertoBackground: Prioritization schemes usually highlight species-rich areas, where many species are at imminent risk of extinction. To be ecologically relevant these schemes should also include species biological traits into area-setting methods. Furthermore, in a world of limited funds for conservation, conservation action is constrained by land acquisition costs. Hence, including economic costs into conservation ...

Local and regional species diversity in South American Falconiformes: a geostat...
Peixoto, Joana de Castro; Souza, Márcia Christianne de; Diniz Filho, José Alexandre Felizola; Bini, Luis MauricioThe relationship between local and regional diversity in Falconiformes assemblages from South America was estimated. However, species richness was spatially patterned across the continent and this result can bias significance levels of regression analyses. To overcome this problem, we determined the minimum distance between localities that ensures stochastic independence of diversity estimates across space, usi...
Emberizidae species richness and conservation conflicts in the Brazilian Cerrad...
Barreto, Bruno de Souza; Oliveira, Guilherme de; Pinto, Miriam Plaza; Bini, Luiz Mauricio; Diniz Filho, José Alexandre Felizola; Blamires, DanielSeveral variables have been used to indicate conflicts between socioeconomic interests and biodiversity conservation. Thus, efforts to minimize biodiversity losses are being based on the analysis of such conflicts, since there is more and more evidence that important sites to conservation could support high population densities and their impacts. However, in the Cerrado this might not be true due to the technol...
Interspecific synchrony in a local assemblage of anurans in Central Brazil: eff...
Bini, Luis Mauricio; Diniz Filho, José Alexandre Felizola; Bastos, Rogerio Pereira; Souza, Marcia Christianne de; Peixoto, Josana de CastroWe studied the pattern of temporal occurrence of 15 amphibians species that coexist in a Brazilian conservation unit from June 1995 to May 1998. Using the resultant binary data matrix, an interspecific association matrix (Jaccard coefficient) was calculated. As a unique local assemblage was temporally surveyed, this matrix represents how pairs of species are temporally associated (interspecific synchrony). Two ...
Spatial patterns and biodiversity conservation of snakes from Cerrado biome
Couto, Larice de Fátima; Terribile, Levi Carina; Diniz Filho, José Alexandre FelizolaUntil recently, the conservation of Cerrado has been neglected and attempts to establish conservation priorities were usually based on subjective criteria. In this paper, macroecological data of distribution of 129 species of snakes in the Cerrado were used to evaluate spatial patterns in species richness and to establish a system of potential areas that preserves all snake species in the region. The five envir...
