Habitat selection by anurofauna community at rocky seashore in coastal Atlantic Forest, Southeastern Brazil/Seleção de hábitat por uma comunidade de anuros em um costão rochoso na Mata Atlântica costeira, sudeste do Brasil

Rocky seashores are low granitic hills distributed along the southeastern Brazilian coast with xeric-like vegetation due to the shallow soil. Knowledge on amphibian communities and their reproductive patterns is especially reduced on this kind of environment. Herein, the authors present a framework of two years monitoring an amphibian community at a rocky seashore environment located at the protected area of Parque Estadual da Serra da Tiririca, municipality of Niteroi, state of Rio de Janeiro, Brazil. They conducted diurnal and nocturnal searches for frogs in tank bromeliads, rocky surface and shrubby vegetation. Annual pattern of breeding activity of anurans was also estimated. Individuals of the most abundant tank-bromeliad, Alcantarea glaziouana were collected and measured according to several variables to understanding the selection of bromeliads by frogs. They checked the influence of the environmental conditions on amphibian abundance, association between the bromeliads measures, and the water storage in the tank.
