1. Blair, Christopher. Ecological factors influencing Eleutherodactylus (Anura:Leptodactylidae) abundance and distribution at five sites in southeastern Peru.

Degree: Department of Biological Sciences, 2006, Central Connecticut State University

Although many researchers have compared herpetofaunal assemblages over large geographical regions, comparisons on a microgeographic scale have been scarce. Thus, the goal of this study was to compare species diversity of Eleutherodactylus on a smaller geographic scale and to determine what variables contributed to frog diversity for each site and group; group referring to total individuals, species, juveniles, adults, males, or females. In addition, data were examined for the two most abundant species, Eleutherodactylus toftae and E. peruvianus. To accomplish this, herpetofaunal surveys were conducted at five sites in the Tambopata region of southeast Peru, including EcoAmazonia (EA), Reserva Amazonica (RA), Explorer's Inn (EI), Sachavacayoc Centre (SC), and Tambopata Research Center (TRC). In addition to sampling and identifying all species of Eleutherodactylus captured, several environmental variables were collected and analyzed, including time of year, time of day, substrate, capture height, leaf litter depth, tree cover, and prey availability (at Las Piedras only). Total frog abundance, species richness, diversity, and community similarity differed significantly between sites. More individuals were captured at SC and TRC than any other site, whereas more total species were captured at TRC and EI. More juveniles were captured at RA, SC, and TRC, whereas males were more abundant at EA and EI. Diversity was the highest at TRC, followed by RA, EI, EA, and SC. Diversity of the two most abundant species, Eleutherodactylus toftae and E. peruvianus, was also significantly different among sites, with one species rarely encountered when the other was extremely abundant. Generally, similarity between sites was not closely related to geographic proximity. For most of the ecological variables analyzed, there were few, if any, site-to-site differences. Generally, more individuals were captured during the wet season at all five sites. Eleutherodactylus peruvianus was also more abundant during the wet season, whereas E. toftae showed mixed results. Significantly more individuals were captured during the night than the day at most sites. However, there was no significant difference in species richness between day and night. Significantly more individuals as well as species were captured on leaves and the ground versus all other substrate types, with more on leaves at night and on the ground during the day. There was no significant relationship between tree diameter and frog abundance for any site. However, significant site and group differences existed for capture height and leaf litter depth. At Las Piedras, no significant relationship was found between total arthropod abundance and frog abundance. Also, there was no relationship between specific arthropod orders and frog abundance, frog family, and frog sex. I conclude that three main factors are contributing to the observed difference in diversity among the five sites and include phylogenetic factors, differences in vegetation and forest type, and… Advisors/Committee Members: Doan, Tiffany M..
