The data contained in child items of this page were developed to support the Species Status Assessments conducted by the U.S. Fish & Wildlife Service and conservation planning for State, Federal, and non-government researchers, managers, landowners, and other partners for five focal herpetofauna species: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). These data were developed by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. The three child items contain the following data: (1)...

This study monitored soil surface elevation change from mangrove forests fertilized with nitrogen and phosphorus from 2018-2021. The mangroves selected at Ding Darling National Wildlife Refuge (NWR) have been previously exposed to high nutrient loading from agricultural discharge into the Caloosahatchee River, which elevated soil phosphorus levels to 3-4 times ambient before treatments were impose. Sea-level rise vulnerability with additional nitrogen and phosphorus is a concern for these mangrove ecosystems.
This collection examines how management of natural and working lands (forests, wetlands, and agricultural land) can enhance community resilience in North Carolina and help the state meet its greenhouse gas emissions goals.
The Northern Gulf of Mexico Sentinel Site Cooperative and the Southeast Climate Science Center developed a new resource - Keeping Pace: A short guide to navigating sea-level rise models! This quick four pager covers the importance of model selection, helpful concepts, model categories, and an example of how to utilize these models to address coastal issues. This resource was largely informed by the Sea-Level Rise Modeling Handbook: Resource Guide for Coastal Land Managers, Engineers, and Scientists, which resulted from a Southeast CSC funded project.
Aim Climate change is expected to result in the tropicalization of coastal wetlands in the northern Gulf of Mexico, as warming winters allow tropical mangrove forests to expand their distribution poleward at the expense of temperate salt marshes. Data limitations near mangrove range limits have hindered understanding of the effects of winter temperature extremes on mangrove distribution and structure. Here, we investigated the influence of extreme freeze events on the abundance, height and coverage of black mangroves (Avicennia germinans ) near their northern range limit in Louisiana. Location Coastal Louisiana, USA. Methods We quantified the relationships between the frequency of extreme freeze events and A. germinans...

Publicly accessible open spaces provide valuable opportunities for people to exercise, play, socialize, and build community. People are more likely to use public open spaces that are close (ideally within walking distance) to their homes. To assess the spatial distribution of access to open space for recreation in the southeastern United States, we constructed an index of open space access based on the size of the largest publicly accessible open space within 10 miles of each point on the landscape, using three distance categories to represent whether people can reach the open spaces by walking (within 0.5 mile), via a short drive (within 3 miles), or via a longer drive (within 10 miles). Using the open space access...
Abstract (from Journal for Nature Conservation): As a zoonotic disease with unprecedented global impacts, COVID-19 may influence how people prioritize issues related to wildlife conservation. Using a nationally representative sample of US residents, we investigated: (1) how COVID-19 affected the relative importance of conservation issues among adults with different political ideologies, and (2) how the pandemic affected political polarization of conservation issues during the 2020 general election in the United States. Conservation issues such as endangered species and controlling zoonotic disease ranked low in importance among the 14 policy issues considered, even lower than environmental issues such as climate...

This data set contains links that are important to each species' habitat network. Those important links are scored based on the percent currently under protection status, projected change in climate suitability by the middle of the 21st century, and projected change in percent urbanized by the middle of the 21st century. Important links were identified from all links in the networks of each species based on their Integral Index of Connectivity (dIIC). Any links with dIIC scores > 0.9 or which connected to nodes with dIIC > 0.9 were retained here as "important" links.

We determined their critical thermal maximum (CTMax) of four species of Eleutherodactylus frogs (E. wightmanae, E. brittoni, E. antillensis, E. coqui) to understand their response to warming temperatures. Data consist of capture history, body condition, and temperature at which the frog exhibited spasms and erratic behavior, which may impair predator avoidance. Our results underscored the potential vulnerability of Eleutherodactylus species exhibiting lower CTMax to the forecasted warming of tropical zones (e.g., E. wightmanae, E. brittoni).
