Dispersão de sementes de Melocactus glaucescens e M. paucispinus (Cactaceae), no Município de Morro do Chapéu, Chapada Diamantina - BA

Abstract: RESUMO(Dispersão de sementes de Melocactus glaucescens e M. paucispinus (Cactaceae), no município de Morro do Chapéu, Chapada Diamantina -BA). Objetivou-se identifi car os dispersores de duas espécies de Melocactus, verifi car o padrão de liberação dos frutos, correlacionando-o com a remoção por frugívoros e variação térmica do cefálio, bem como caracterizar a distribuição espacial. Para tanto, foram realizadas observações focais, testes de germinação, registros da emergência, extrusão e remoção de frutos, da … Show more

“…5j). Although saurochory is considered predominantly an island phenomenon (Olesen and Valido 2004), recent reports of dispersal by lizards in campo rupestre (Fonseca et al 2012) suggest that this mechanism of seed dispersal may also be relevant. There are no studies on seed dispersal by bats in campo rupestre.…”

“…Many species of the Melocactus genus are listed under IUCN red list (15 of 37 species; IUCN 2012) and CITES appendices (34 of 37 species; UNEP-WCMC 2013) largely due to a decline in its populations caused by illegal collecting and habitat destruction (Taylor 1991(Taylor , 2002. The taxonomy and morphology of the genus were studied in detail (Taylor 1991), but only recently studies in reproductive biology (Nassar & Ramírez 2004, Colaço et al 2006, Nassar et al 2007, Fonseca et al 2008, seedling mortality (Hughes et al 2011), population genetics (Nassar et al 2001, Lambert et al 2006a, 2006b, and seed dispersal (Figueira et al 1994, Fonseca et al 2012 started to fill the knowledge gap regarding the ecology of this genus.…”
