Location: Wentworth 9

Dynamic Instability of Coqui Frog Populations on Hawaiʻi Island
Speaker: Dr. William Mautz; Department of Biology/TCBES

Monday, 9th November, 4 pm - Wentworth 9, UH Hilo campus.

Study of coqui frog (Eleutherodactylus coqui) populations was made in 2006 and 2007 to compare densities of frogs in forest habitats dominated by albizia trees (Falcataria moluccana) and habitats dominated by ʻohiʻa trees (Metrosideros polymorpha). The hypothesis that albizia-dominated habitats, with greater primary productivity, would have greater numbers of frogs was not supported.

With 2 replicate sites in each forest type and 3 replicate 20 x 20 m plots at each site, frog population densities were measured by mark recapture of sub-adult and adult frogs and counts of juveniles. Variation of population density among replicate plots and between replicate sites within forest types was large and obscured differences possibly due to forest type. Replicate plots within a site were within 100 m of each other in, by all appearances, a uniform habitat.

Despite the close proximity of plots, body size distributions of frogs representing age structure, were surprisingly different among replicate plots. At this 2006-2007 stage of the coqui frog invasion, a continuously distributed population over the landscape of both forest types had a large variation in age structure over small (100-m) spatial scales.

Special Restrictions: All are welcome!
