Ecologia trófica de larvas de peixes neotropicais : interações intra e interesp...
Rosa, Rafael RogérioThe survival and growth of fish larvae during ontogeny are related to the ability to obtain adequate food, providing subsidies for individuals reach the adult age. The foraging capacity, availability and abundance of prey and morphological development, especially swimming performance and visual acuity are important factors in reproductive success. In this study, the aspects related to feeding during the ontogen...
Climate change will decrease the range size of snake species under negligible p...
Lourenço-de-Moraes, Ricardo; Lansac-Toha, Fernando Miranda; Schwind, Leilane Talita Fatoreto; Arrieira, Rodrigo Leite; Rosa, Rafael RogérioMade available in DSpace on 2019-10-06T15:47:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-12-01; Reptiles are highly susceptible to climate change, responding negatively to thermal and rainfall alterations mainly in relation to their reproductive processes. Based on that, we evaluated the effects of climate change on climatically suitable areas for the occurrence of snakes in the Atlantic Forest ho...
Sucesso reprodutivo de Salminus brasiliensis (Cuvier, 1816) : variações intra e...
Rosa, Rafael RogérioThe reproduction of freshwater fish occurs annually in environments that provide favorable environmental conditions for spawning and subsequent survival and growth of their larvae. The aim of this study was to evaluate the spatial and temporal distribution of larvae Salminus brasiliensis in order to understand the intra and interannual variations in their abundance and the influence of environmental variables o...
Fish diversity from tributaries of the Chavantes Reservoir, upper Paraná River ...
Rosa, Rafael Rogério; Caetano, Dyego Leonardo Ferraz; Bellay, Sybelle; Moraes, Verônica Rodrigues de; Vieira, Fernando Emmanuel GonçalvesDistribution and abundance of stream fish species can be influenced by environmental characteristics related to the aquatic environment and its margins. The objective of this study was to inventory the ichthyofauna of the Cruz, Taquaruçu, and Taquaruçu II streams, in the Paranapanema River basin, and to analyze the diversity parameters and associate them with abiotic variables. A total of 4,956 specimens were c...
Influence of an artificial dam on the fish assemblage of a Neotropical stream
Caetano, Dyego Leonardo Ferraz; Rosa, Rafael Rogério; Moraes, Verônica Rodrigues de; Jané, Daniela Ribas; Silva, Alexandre Fernandes Oliveira daThe objective of this study was to evaluate the influence of a dam on the ecological parameters of the fish assemblages of a stream of second order of the upper Paraná River basin, southern Brazil. Samplings of abiotic data and ichthyofauna occurred quarterly between September 2012 and June 2013. Were collected 3,128 individuals in six orders, eight families and 13 species. The Cluster analysis (Jaccard) based ...
