Habitat fragmentation, modification, and loss have been implicated in the decline of many species, including more than 85% of those considered threatened or endangered. Therefore, connectivity, or the ability of organisms to move among habitat patches, is a critical component of landscape health. In addition to influencing the sustainability of wildlife populations and communities, connectivity also contributes to the availability of ecosystem services. The goal of this project was to evaluate terrestrial connectivity across the South Central United States, with a focus on the impact of projected climate and land use changes. The researchers addressed this goal using a variety of approaches, including evaluating...

As effects of climate change intensify, there is a growing need to understand the thermal properties of landscapes and their influence on wildlife. A key thermal property of landscapes is vegetation structure and composition. Management approaches can alter vegetation and consequently the thermal landscape, potentially resulting in underappreciated consequences for wildlife thermoregulation. Consideration of spatial scale can clarify how management overlaid onto existing vegetation patterns affects thermal properties of landscapes relevant to wildlife. We examined effects of temperature, fire management, and vegetation structure on multi-scale habitat selection of an ectothermic vertebrate (the turtle Terrapene...

Soil moisture depletion during the growing season can induce plant water stress, thereby driving declines in grassland fuel moisture and accelerating curing. These drying and curing dynamics and their dependencies on soil moisture are inadequately represented in fire danger models. To elucidate these relationships, grassland fuelbed characteristics and soil moisture were monitored in nine patches of tallgrass prairie under patch-burn management in Oklahoma, USA, during two growing seasons. This study period included a severe drought (in 2012), which resulted in a large wildfire outbreak near the study site. Fuel moisture of the mixed live and dead herbaceous fuels (MFM) clearly tracked soil moisture, expressed as...
