Resumen

BABINI, María Selene; SALAS, Nancy Edith; BIONDA, Clarisa de Lourdes  y  MARTINO, Adolfo Ludovico. Implications of urbanization on the presence, distribution and reproductive ecology of the anuran fauna of a city in central Argentina. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.1, pp.188-195. ISSN 2007-8706.  http://dx.doi.org/10.7550/rmb.43684.

Urbanization disrupts the natural ecosystem and causes the decline of amphibian populations. In this study, an inventory of anuran species that are present in a city central Argentina is presented and their reproductive aspects associated with urban environments are analyzed. Eighteen sampling sites were selected and classified according to the stability of the body of water, in four different environments: 1) permanent, 2) semipermanent, 3) semitemporal and 4) temporal. To determine the reproductive activity, the acoustic emissions and the presence of larval stages were recorded. The indexes of alpha and beta diversity, relative importance (IIR) and permanence (IP) were calculated. To compare the diversity among environments a Hutcheson's t-test was performed. There were 8 species of anurans. Rhinella arenarumhad the highest IP and IIRThe species Leptodactylus gracilis , L. latinasus and R. arenarum occupied more sites. The semitemporal environment showed the highest diversity and less variation in abundance among species. The lowest diversity was recorded in the permanent environment. Due to the special requirements of the species, the diversity of environments with different hydroperiods is a key factor for the preservation of a community of urban frogs.
