Marbled Salamander Reproductive Ecology: Ambystoma opacum (Marbled Salamander)
Location: Kisatchie National Forest; Kisatchie District, Kisatchie Bayou Campground Area; Years: 2010, 2011
The primary goal of this study is to investigate nest ecology and dynamics in marbled salamanders in Kisatchie District of Kisatchie National Forest.

Ambystomatid Salamander Monitoring at Kisatchie National Forest: Ambystoma opacum , Ambystoma maculatum , Ambystoma texanum , Ambystoma talpoideum (Marbled Salamander, Spotted Salamander, Small-mouthed Salamander, Mole Salamander)
Location: Kisatchie National Forest; Kisatchie District, Kisatchie Bayou Campground Area; Years: 2010, 2011
The goals of this study are to 1.) estimate the number of adults of each species using the pond, 2.) determine the reproductive effort of adults (number of egg masses), 3.) estimate the density of larvae and predators in the pond, and 4.) examine the yearly variability in phenology of breeding among species.

Potential impacts of salinity on anuran occupancy dynamics at Big Thicket National Preserve: Hyla cinerea , Gastrophryne carolinensis , Acris blanchardi , Lithobates clamitans , Lithobates catesbeianus , Lithobates sphenocephalus , Incilius nebulifer (Green Tree Frog, Eastern Narrow-mouthed Toad, Blanchard's Cricket Frog, Green Frog, American Bullfrog, Southern Leopard Frog, Gulf Coast Toad)
Location: Big Thicket National Preserve; Beaumont Unit, Big Thicket National Preserve; Years: 2010, 2011
The goal of this study is to monitor anuran occupancy using standard protocols while also recording salinities, as this area is below a salwater barrier on the Neches River and is susceptible to saltwater encroachment during tropical storm surges or periods of drought, which may impact anuran occupancy.

Mechanical disking to herbicide treatments in waterfowl managed ponds: The effect of management changes on amphibians: Hyla cinerea , Acris crepitans , Gastrophryne carolinensis , Pseudacris crucifer , Anaxyrus fowleri , Lithobates catesbeianus , Lithobates sphenocephalus (Green Tree Frog, Northern Cricket Frog, Eastern Narrow-mouthed Toad, Spring Peeper, Fowler's Toad, American Bullfrog, Southern Leopard Frog)
