Diet of Dendropsophus microcephalus and Scarthyla vigilans (Anura: Hylidae) at a locality in north-western Venezuela with notes on microhabitat occupation

Abstract

The coexistence of species with similar ecological requirements (food, space, time) Agelenidae (11.1%), Tachinidae (9.32%) and . Gryllidae (14.13%), Cicadidae (9.1%), Cicadellidae (8.3%) and Delphacidae (8.02%)

Anurans trophic dynamic and guild structure in tropical dry forests of the Caribbean region of Colombia

“…Our results show that at the Order level, the overlapping is evident but not at higher levels of taxonomic resolution such as families or morphospecie. This classification reveals broadscale trophic patterns not detectable when working at a more detailed prey level, such as species or morphospecies (Piatti & Souza 2011, Fonseca-Pérez et al 2017. At a spatial scale, the sites were dissimilar in composition and abundance of species and morphospecies of prey.…”

“…Taking into account the high diversity of insects in tropical forests, no overlap is observed at higher taxonomic resolution levels such as family or morphospecies (García-Robledo et al 2020). These levels can be used to analyze diet variability locally and correctly identify the segregation of trophic niche, especially when the general pattern indicates overlap (Piatti & Souza 2011, Fonseca-Pérez et al 2017. The coexistence of species that have overlapping diets may be explained in part by the high abundance of the resource and by the segregation of prey at higher taxonomic resolution levels.…”

Vertical Segregation in Pristimantis Species From a Bamboo Forest in Southeast of Amazonia, Brazil

“…Several studies have focused vertical stratification in Anura (Arroyo et al, 2008;Muñoz-Guerrero, 2007;Guayasamin and Funk, 2009;de Menezes Gondim, 2013;Fonseca-Pérez, 2017). To explain this behavioral and ecological activity, different strategies are used by the anuran species to coexist in the same habitat: ontogenetically (Eterovick et al, 2010, de Menezes Gondim, 2013, foraging sites and competition inter and intraspecific (Duellman and Pyles, 1983;Toft, 1985), and by attracting females during the breeding season by strategic vocalization frequencies in males (Miyamoto, 1982).…”
