Bancos De Macrófitas Aquáticas Como Locais De Desenvolvimento Das Fases Iniciais De Peixes Em Várzea Do Baixo Amazonas

Abstract: Resumo: O estudo descreve a composição e estrutura da comunidade de larvas e juvenis de peixes associada a bancos de macrófitas aquáticas e avalia a importância dessas vegetações para o desenvolvimento dos estágios iniciais de vida da ictiofauna em uma ilha aluvial no Baixo Amazonas, Pará, Brasil. As amostragens foram realizadas durante os momentos de cheia/vazante de 2017 (ciclo I) e enchente de 2018 (ciclo II) em bancos de macrófitas por meio de um peneirão (malha 500 µm). Em laboratório os indivíduos foram … Show more

“…Thus, this stage of food transition that occurs in preflexion, for T. auritus , is characterized as a critical phase of complex adaptations, in which larvae need to find adequate food before completely ending their endogenous reserves (Kamler, 1992; Moguel‐Hernández et al., 2016; Ponte et al, 2016). However, the success in survival of the early stages of T. auritus is closely linked to the larva's ability to reach complex environments such as lowland areas, composed of aquatic macrophytes, which are conducive to the feeding, protection, and growth of these individuals (Oliveira, Cajado, et al., 2020; Zacardi, Bittencourt, et al., 2020).…”

“…T. auritus larvae in the preflexion stages are pelagic and transparent (Cajado et al., 2020), to pigmentation in that period represents an adaptive camouflage strategy in the water column and avoids attracting attention from visual predators (Sanches et al., 2001; Silva et al., 2021). While in the final stages of development, most of these individuals are colonizing water macrophyte stands (Oliveira, Suzuki, et al., 2020; Oliveira, Cajado, et al., 2020). In this way, intense pigmentation acts as camouflage while using structured environments (Machado‐Allison et al., 2020; Santos et al., 2017).…”

“…This dynamic allows the transport of organisms to flooded wetlands, with high productivity and complex habitats (e.g. aquatic macrophytes), which favors biological recruitment (Nakajima et al., 2017; Oliveira et al., 2020; Stuart & Sharpe, 2020; Zacardi et al., 2020).…”
