Abstract: The investigation of historical factors which determine assemblage structure is largely based on the idea that closely-related species have similar ecological characteristics due to a shared evolutionary history. We used a Pseudocommunity Analysis (PA), Principal Component Analysis (PCA) and Canonical Phylogenetic Ordination (CPO) to evaluate the influence of phylogeny on microhabitat use, diet composition and morphology in an assemblage of 15 anuran species occupying temporary ponds in the semiarid Caatinga. Closely-related species used the same microhabitats, although at different proportions, and showed a high diet niche overlap. The PA showed that competition does not appear to regulate the assemblage. Closely-related species showed a high degree of morphological similarity, suggesting that body shape is a conservative trait. The CPO analysis revealed a historical influence on microhabitat use in the Hylidae and Leptodactyliformes dichotomy, and in the diet composition of the genus Physalaemus and Leiuperinae. Although resource use patterns reflect phylogenetic relationships among species, our results suggest that ecological factors such as competition further shaped the studied anuran assemblages.

IMPORTANT NOTE - JUNE 2020

Please note that as from Volume 31 Number 1 (January 2021) on, the Herpetological Journal will be available as an online publication only - the last print edition will be Volume 30 Number 4.   

Aligning with this change, it is now no longer possible to purchase a subscription that includes a print copy of the HJ.  All members who have existing HJ print subscriptions that remain active as at end June 2020 will receive the full four 2020 print editions.  New subscribers or renewals after this time will only have option to subscribe to the online only subscription package.  Subscription pricing has been amended to reflect the content changes.
