Temporal and ontogenetic variations in feeding habits of Hollandichthys multifasciatus (Teleostei: Characidae) in coastal Atlantic rainforest streams, southern Brazil

Abstract: Feeding habits of the characin Hollandichthys multifasciatus were investigated. Samplings were made between March 2004 and February 2005 in two black water streams of the coastal Atlantic rainforest in southern Brazil. The diet, evaluated by qualitative and quantitative methods, included aquatic and terrestrial insects, decapods, oligochaetes, plants and spiders. Large individuals feed mainly on plants, terrestrial insects, and spiders, whereas small fish feed basically on plants and oligochaetes. The species … Show more

“…Despite the fact that the analysis of similarities (oneway and two-way) revealed that the intake of insect preys (aquatic immature stages and terrestrial species) by R. luelingi changed during the studied period, no relation between the estimated contribution of these items and high/ low precipitation period was observed. Thus our results fail in demonstrated the expected seasonal variation in the feeding habits of the small-sized fish species (LoweMcConnell, 1987;Prejs & Prejs, 1987) as already registered for the Atlantic Rainforest streams (Deus & Petrere-Júnior, 2003;Mazzoni & Rezende, 2003;Abilhoa et al, 2007;Vitule et al, 2008; and suggest similarities in the allochthonous matter input between rain and dry seasons.…”

“…These drainages are inhabited basically by small-sized fish species, which dwell in streams or shallow water of rivers, showing sometimes a high rate of speciation and a high degree of geographic endemism (Castro, 1999). Despite the evergrowing increase in the distribution data (e.g., Bizerril, 1994;Oyakawa et al, 2006;Menezes et al, 2007;Abilhoa & Bastos, 2009;Bertaco, 2009) and feeding ecology documentation (e.g., Graciolli et al, 2003;Mazzoni & Rezende, 2003;Abilhoa et al, 2007Mazzoni & Costa, 2007;Mazzoni et al, 2010) of the small-sized fish species, there is still scarce information on several species.…”

“…Verificamos que a dieta de A. janeiroennsis apresentou predomínio, quase absoluto, de itens autóctones nas localidades fechadas, fato que ressalta a importância dos processos internos na manutenção de sistemas fluviais de baixa ordem. Nossos resultados enfatizam a importância da produção autóctone para a manutenção da espécie no riacho estudado o que nos opõe aos resultados mais comuns sobre ecologia trófica de riachos, que sempre apontam para a importância do aporte de matéria alóctone proveniente da mata ripária (Welcomme 1985, Moulton & Magalhães 2003, Abilhoa et al 2009). Apesar de nossos resultados contrastarem com muitos registros da literatura, acreditamos que o comportamento de forrageamento da espécie, amplamente apoiado no oportunismo, explique os resultados encontrados e não invalidem a importância da vegetação ripária para a manutenção da integridade dos riachos de baixa ordem.…”

“…3 Introdução Diversos registros da literatura sobre os hábitos alimentares de peixes de riacho têm demonstrado importante dependência da floresta circundante como fonte de importação dos recursos alimentares (e.g. Costa et al 1987, Aranha et al 1998, Abilhoa et al 2007, Dufech et al 2003, Rezende & Mazzoni 2006a. De fato, diversas espécies de peixes têm sua dieta amplamente baseada em recursos de origem alóctone (Lowe-McConnell, 1991) e alterações na vegetação ripária mostraram ter efeito direto na dinâmica da alimentação dessas espécies de riacho (Casatti 2002, Rezende & Mazzoni 2006b.…”
