Wild turkey is a culturally and economically important game species that has shown dramatic population declines throughout much of the southeastern U.S. A possible explanation for these declines is that the timing of nesting has shifted to earlier in the year while hunting seasons have remained the same. Wild turkeys are the only gamebird in the contiguous United States that are hunted during the reproductive season, so premature harvest of adult male turkeys may disrupt reproductive behaviors and reduce population growth. In addition to hunter harvest, climate change can also impact population growth of wild turkeys. Local and broad-scale regional changes in precipitation and temperature associated with a changing...

Brook trout are the only native fish from the salmon family in the southeastern United States. Despite their recreational and cultural significance, human activities, such as habitat degradation and introduction of non-native species, have led to serious declines of brook trout populations in the region. Stream temperature and flow alterations from climate change are projected to impact this cold-water species even further. Recent studies show that there is much site-to-site variation in how climate affects stream temperature and flow. Therefore, vulnerability of local trout populations to climate change also varies. Understanding local variation in climate responses across the region is critical to maintaining...

Species are on the move as they respond to climate change. This includes many native species, but also species with high costs to society such as disease vectors, pests, and nonnative invasive species (an invasive species is a species that is not native to a specific location but is spreading with the tendency of causing damage to native plants and animals). Currently there are hundreds of invasive species with relatively restricted ranges in the southeastern U.S., but as the climate changes these species are expected to expand their ranges to new regions. It is important to understand if and how these species might move and what actions we can take to lessen their impact on species and habitats. To achieve this...

The ability to effectively manage wildlife in North America is founded in an understanding of how human actions and the environment influence wildlife populations. Current management practices are informed by population monitoring data from the past to determine key ecological relationships and make predictions about future population status. In most cases, including the regulation of waterfowl hunting in North America, these forecasts assume that the relationships we observed in the past will remain the same in the future. However, climate change is influencing wildlife populations in many dynamic and uncertain ways, leading to a situation in which our observations of the past are poor predictors of the future....

The climate of the Southeast is changing rapidly. As streams warm and streamflow dynamics change due to climate and land-cover changes, previously unsuitable habitats may become hospitable for invasive species. Warmwater and large-river adapted invasive species such as Asian carps may move upstream as habitats that were previously too cold or had too little flow become welcoming environments for them as climate changes. The spread of invasive species will likely impact native fishes and dependent local economies like fishing and tourism. Within the Southeast, the Tennessee and Cumberland River Basins, located across 7 different US states, are among the most important in terms of total, narrow-ranged, and at-risk...

Much of the biodiversity of the southeastern U.S. is found in grasslands, including meadows, prairies, glades, and savannas. These grasslands provide vital habitat to a variety of plants and animals, but many grassland types have undergone over 90% loss due to fire suppression and urban sprawl. The remaining grassland patches—remnants—now face emerging threats from invasive species and climate change. The project researchers recently convened a workshop with grassland managers and experts from across the Southeast, from Texas to West Virginia to Florida, to identify the most pressing science needs to effectively manage and restore grasslands over the coming decades. This project directly addresses those needs by...
