Effects of fish on reptile and amphibian community assemblages in wetlands of variable permanence
Title
Effects of fish on reptile and amphibian community assemblages in wetlands of variable permanence.
Creator
Holbrook, Joshua D., Dorn, Nathan, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
Many herpetofaunal species are imperiled, and the causes of this are often a synergy of multiple factors. In wetlands specifically, two of the possible determinants of species occurrence and faunal community assemblage are fish presence and wetland permanence, which are not always correlated. Twenty wetlands were sampled in Jonathan Dickinson State Park, Florida, USA to observe how wetland herpetofaunal communities vary with fish, wetland permanence and other environmental factors....
Show moreMany herpetofaunal species are imperiled, and the causes of this are often a synergy of multiple factors. In wetlands specifically, two of the possible determinants of species occurrence and faunal community assemblage are fish presence and wetland permanence, which are not always correlated. Twenty wetlands were sampled in Jonathan Dickinson State Park, Florida, USA to observe how wetland herpetofaunal communities vary with fish, wetland permanence and other environmental factors. Herpetofaunal communities with and without fish were significantly different from one another and differences between herpetofaunal communities were primarily due to the contribution of four species of frogs, two generalist ranids and two specialist hylids. Wetland permanence had no observable effect on community structure. Fishless wetlands were significantly more species-rich and possessed higher numbers of individuals even for species that occurred in both fishless and fish wetlands, regardless of their permanence. These findings have implications for wetlands restoration and herpetofaunal conservation.

Anurans of Abacoa
Title
Anurans of Abacoa.
Creator
Vuong, Wei Mien., Harriet L. Wilkes Honors College
Abstract/Description
The construction of Abacoa included an attempt to conserve the wildlife in a Greenway, a set of habitats separated from the residential and commercial areas. All of the wetlandswith in Abacoa represent artificially constructed ponds, canals, and streams first created from 1998-2004. The present study focuses on the anuran (i.e., frog and toad) populations and looks at the number of different species that have naturally colonized six differnet sites around Abacoa. Each of these sites varies in...

All of the wetlandswith in Abacoa represent artificially constructed ponds, canals, and streams first created from 1998-2004. The present study focuses on the anuran (i.e., frog and toad) populations and looks at the number of different species that have naturally colonized six differnet sites around Abacoa. Each of these sites varies in qualities that may affect the probability of breeding in that section. The quality of water is known to be less ideal as the water flows away from the headwaters and mixes with water from other sources. This study aims to determine which anuran species are found at each of these sites after nearly a decade of colonization, and how both anuran diversity and abundance correlates with water and habitat quality.
