The pine rockland ecosystem is found only in south Florida and the Bahamas and provides important habitat for numerous rare and endemic plants and animals. These include 18 species that are already federally listed as threatened or endangered and four other species petitioned for listing that are scheduled for development of Species Status Assessments (SSAs). Today, south Florida’s pine rockland ecosystem represents less than 3 percent of its original extent. Threats such as saltwater intrusion from hurricanes and sea-level rise pose the greatest risk to the longevity of this ecosystem. For the U.S. Fish and Wildlife Service to make decisions about the potential listing of a species, they must be able to forecast...

We measured environmental variables at multiple spatial scales and their effect on three physiological health metrics of ornate chorus frog (Pseudacris ornata) tadpoles to identify potential correlates of population declines. To accomplish this, we measured corticosterone (glucocorticoid hormone associated with the stress response in amphibians) release rates, as well as the skin mucosal immune function (combined function of skin secretions and skin microbial community) and microbial communities of tadpoles from multiple ponds. We found that water quality and land cover characteristics associated with environmental degradation, including increased water temperature, conductivity, pH, land cover, and development...
