- Description
- We assessed the relationships between anuran use and habitat characteristics at 93 ponds. We recorded pond-scale (within 100 m) and landscape-scale (within 500 m) habitat variables and used a generalized linear model framework to determine which variables, if any, related significantly to total anuran abundance, species richness,and the presence and/or abundance of individual species. We recorded 33 species and modeled the distributions of nine. Species richness increased with increasing emergent vegetation and the presence of sandstone, and decreased as the Prescott Index (a measure of ground moisture), elevation, and latitude increased. Total anuran abundance increased with increasing emergent vegetation and pond area and decreased with elevation, pond density, and the Prescott Index. No consistent patterns were evident in the variables showing significant relationships with the presence and/or abundance of individual species. The variables most commonly found to relate to the presence/abundance of individual species were pond shading (appeared in models for eight species) and tree height (six species). Models explained up to 64% of the deviance for presence-absence and 48% for abundance, but usually explained < 35% deviance. Local scale variables were slightly more prevalent in models, but did not obviously have greater influence on the species studied. There was no pattern evident based on phylogeny. Managing species in these forests will need to consider multiple scales and multiple features of the environment.
