Abstract: CETRA, M., RONDINELI, G.R. & SOUZA, U.P. Resource sharing by two nectobenthic freshwater fish species of streams in the Cachoeira river basin (BA). Biota Neotrop. 11(2): http://www.biotaneotropica.org. br/v11n2/en/abstract?article+bn01911022011. Abstract:The aim of this study was to investigate specific characteristics and common features related to the abundance and the gradient of environmental conditions and food resources used by Trichomycterus bahianus and Characidium aff. zebra. These species are two typ… Show more

“…Resource partitioning among fish species from Neotropical streams is well reported in the literature, where the wide variety of aquatic and terrestrial organisms available as potential prey items leads to a wide diversity of tactics and feeding habits (Casatti, 2002;Barreto & Aranha, 2006;Abilhoa et al, 2008;Brandão-Gonçalves et al, 2010;Alves et al, 2011;Cetra et al, 2011;Uieda & Pinto, 2011).…”

“…Both stochastic processes and the abundance of some foods may reduce intraspecific competition, facilitating the species' coexistence (Dias & Fialho, 2011;Uieda & Pinto, 2011). Other factors such as trophic morphology, use of different microhabitats, periods of activity, and tactics of capture can minimize overlap effects (Casatti, 2002;Brazil-Sousa et al, 2009;Cetra et al, 2011).…”

“…For ecological purposes it is important to evaluate which environmental conditions present limitations to communities (Cetra et al, 2011). According Rivas (1964) the term syntopic to be used in reference to two or more related species which occupy the same locality (macrohabitat).…”

“…Other factors such as the trophic morphology, the use of distinct microhabitats, activity periods and feeding strategies may minimize overlapping effects (Casatti, 2002;Brazil-Sousa et al, 2009;Cetra et al, 2011). The use of morphologic attributes may reflect an integration of a broad variety of ecosystem influences to the organisms which live inside those systems, mainly for aquatic organisms and are suited to define morphologic and ecologic similar patterns (Winston, 1995).…”

“…Na literatura científica há apenas menções sobre os itens alimentares consumidos por C. rachovii (Corrêa et al, 2010) e sobre a frequência de ocorrência destes (Fernandez et al, 2012). Estes estudos preliminares sobre a alimentação de C. rachovii (Corrêa et al, 2010;Fernandez et al, 2012) e outros trabalhos com espécies congenéricas (Sabino & Castro, 1990;Aranha et al, 2000;Motta & Uieda, 2004;Barreto & Aranha, 2006;Ferreira, 2007;Gomiero & Braga, 2008;Braga & Gomiero, 2009;Cetra et al, 2011;Mazzoni et al, 2012) mostraram uma maior representatividade de insetos imaturos (estágios aquáticos, principalmente larvas de dípteros) e crustáceos na dieta.…”
