ABSTRACT.-I studied the use of calling and retreat sites by Phyllodytes luteolus in an ornamental bromeliad garden where phytotelmata in bromeliad leaf axils are abundant. I investigated individual spacing and activity patterns. Among the nine bromeliad species cultivated in the garden, the frogs used Vriesia neoglutinosa and plants structurally similar to it more than expected according to their availability. Phyllodytes luteolus uses V neoglutinosa in its natural habitat. For one bromeliad species (Sp 1), frogs usedproportionally more those plants that were higher (57.7 ? 8.4 cm above ground), had lower pH (4.94 ? 0.88), and deeper phytotelmata (5.38 ? 2.09 cm). Plant height, phytotelmata depth, and pH had no influence on frogs' choices in the other bromeliad species tested. Males were active all night, and calling activity was highest immediately after sunset. Some males called during the day. Males did not exibit aggressive behavior towards other males, including those intruding onto their c...

Journal of coastal conservation: a review on the anurofauna of Brazil’s sandy coastal plains. How much do we know about it?

“…The hypothesis most frequently adopted to explain the difference in use of bromeliads by amphibians is the ability of individuals to use those plants which present better characteristics in terms of the structural architecture of the plant Teixeira 2001, Silva et al 2011) such as leaf number, shape, size of bromeliad (Oliveira and Rocha 1997a, b) or reserve capacity of water (Cogliatti-Carvalho et al 2010). Thus, amphibians should select different features in bromeliad species that are more favourable and complementary to their needs, so that the set of morphological and physiological characteristics must interact to determine the association degree between anuran and bromeliad in the restinga (Eterovick 1999;Silva et al 2011). The fact that amphibian species with larger sizes (for example, Aparasphenodon brunoi) generally use larger plants, such as Aechmea lingulata, for shelter during the day (Teixeira et al 2002) supports this idea.…”

Patterns of Spatial Distribution and Microhabitat Use by Syntopic Anuran Species along Permanent Lotic Ecosystems in the Cerrado of Southeastern Brazil

“…Bokermannohyla circumdata group and B. nanuzae, for instance, frequently used arboreal and terrestrial bromeliads, respectively. Other studies already pointed to the importance of bromeliads as microhabitats for many hylids (Bastazini et al, 2007;Eterovick, 1999;Giaretta, 1996;Schineider et al, 2001). Decreased predation risk, as well as high moisture of phytotelmata within leaves, may be factors that favored use of this microhabitat by species at our study site.…”

Oviposition site selection in a complex and variable environment: the role of habitat quality and conspecific cues

“…In frogs breeding in phytotelmata it is common for males to select oviposition sites to which they attract females (Eterovick 1999;Jungfer 2000;Bourne et al 2001;Heying 2001). In our study, the model of male presence at possible spawning sites included the same abiotic parameters as the model for oviposition except maximal possible water depth, suggesting that P. guineensis males select breeding sites with respect to abiotic habitat characteristics similar to those shown by female preferences.…”
