The eastern black rail (Laterallus jamaicensis jamaicensis; hereafter rail) is a small, cryptic marshbird that was recently listed as threatened under the U.S. Endangered Species Act. We organized a rapid prototyping workshop to initiate development of an adaptive management for rails on the Atlantic Coast. The in-person workshop spanned 2.5 days and was held in Titusville, Florida in January 2020. Workshop participants, comprised of species experts and land managers of rail habitats, chose to focus the framework on testing habitat management techniques to maximize rail occupancy, in which uncertainties could be reduced through a combination of field management experiments and coordinated monitoring. We used the...

The American alligator (Alligator mississippiensis) is a species of ecological and economic importance in the southeastern United States. Within South Carolina, alligators are subject to private and public harvest programs, as well as nuisance removal. These management activities can have different impacts across alligator size classes that may not be apparent through widely-used monitoring techniques such as nightlight surveys. We synthesized multiple datasets within an integrated population model (IPM) to estimate size class-specific survival and abundance estimates, that would not be estimable through separate, non-integrated modeling frameworks. The IPM framework included a multistate mark-recapture-recovery...

This dataset comprises whole blood mercury concentrations, sex, predicted age, snout-vent length, and body mass index in American alligators (Alligator mississippiensis) captured at Yawkey Wildlife Center, South Carolina, from 2010 to 2017. A companion dataset for the Florida population located at Merritt Island National Wildlife Refuge (Nilsen et al. 2019) can be found on the Mendeley repository at https://data.mendeley.com/datasets/vycpgt6ycf/1. Funding for this study was provided by the U.S. Geological Survey (Cooperative Agreement nos. G12AC20329, G15AC00264) and the South Carolina Department of Natural Resources (Grant nos. 2009094, 20100899). Alligators are an effective sentinel species for Hg biomonitoring...
