Fitossociologia de um brejo de altitude no semiárido brasileiro: variação das espécies dominantes ao longo do gradiente altitudinal

Abstract: Neste estudo, objetivou-se caracterizar a composição e estrutura da comunidade arbórea da Serra dos Cavalos, em Pernambuco, buscando inferir sobre a influência do gradiente altitudinal na variação das espécies de maior Valor de Importância (VI). Para isto, foi realizado um estudo fitossociológico em que foram mensurados todos os indivíduos vivos com circunferência a altura do peito (CAP) > 15 cm. Foram avaliados os descritores fitossociológicos clássicos em três diferentes níveis altitudinais (base, nível i… Show more

“…Brejos de Altitude represent forest refuges enclaved in the Caatinga domain ( Pereira-Filho and Montingelli 2011 ). These areas are a mosaic composed of Atlantic Forest and Amazon biotic components, and they have climatic, edaphic, and topographical features different from their semiarid surroundings ( Borges-Nojosa and Caramaschi 2003 ), and harbor a peculiar biodiversity of amphibians and reptiles (e.g., Pereira-Filho and Montingelli 2011 ; Castro et al 2019a , b ; Quirino et al 2019 ), insects (e.g., Silva et al 2007 ; Santos et al 2011 ; Silva et al 2019 ), and plants (e.g., Rodal et al 2005 ; Machado et al 2012 ; Araujo et al 2019 ). The Brejos de Altitude possibly originated from climatic fluctuations that occurred during the Pleistocene, allowing the expansion of Atlantic Forest into currently semiarid locations in areas with a favorable microclimate during the shrinkage process ( Behling et al 2000 ; Auler et al 2004 ; Silveira et al 2019 ).…”
