Location: The area of inference for the data from 2002-2006 is the northern part of the Atchafalaya Basin n...; Atchafalaya Basin; Years: 2002, 2003, 2004, 2005, 2006, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015
The primary goal here is to accomplish long-term monitoring of the diverse anuran assemblage in this large bottomland hardwood area. Additional research questions centered on the effects of changes in hydrology will also be addressed.

Location: The inference area is primarily all of Kisatchie Bayou Campground Area east of Kisatchie Bayou, w...; 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
Location: The area of inference is a bottomland swamp north of I10 extending about 7 km, east of Beaumont, ...; Beaumont Unit, Big Thicket National Preserve; Years: 2010, 2011, 2012, 2013, 2014, 2015
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. We also added 20 sites north of the saltwater barrier as reference sites.
Anuran Occupancy Among WRP and Ag Lands
Location: We had 30 WRP sites and 20 Ag sites in the Delta from southern Coahoma County to northern Warren ...; Mississippi Delta; Years: 2008
We used anurans as an indicator to assess the conservation benefits of the Wetlands Reserve Program (WRP). WRP sites were compared to agricultural sites, which is prevalent throughout the Mississippi Delta. Anuran occupancy is suited as an indicator of the conservation benefits of the WRP because it is robust to variation in the observation process (i.e. imperfect detection) and provides a useful metric for comparison across sites.

Location: Lower Mississippi Valley in Lower White/Cache River Basins in Arkansas; Arkansas - Lower White/Cache River Basins; Years: 2006, 2007
