A growing number of mammal species are recognized as heterothermic, capable of maintaining a high-core body temperature or entering a state of metabolic suppression known as torpor. Small mammals can achieve large energetic savings when torpid, but they are also subject to ecological costs. Studying torpor use in an ecological and physiological context can help elucidate relative costs and benefits of torpor to different groups within a population. We measured skin temperatures of 46 adult Rafinesque's big-eared bats (Corynorhinus rafinesquii) to evaluate thermoregulatory strategies of a heterothermic small mammal during the reproductive season. We compared daily average and minimum skin …

Understanding the temporal and spatial scale at which habitat alteration impacts populations is important for conservation and management. Amphibians have declined more than other vertebrates, and pond-breeding species are particularly susceptible to habitat loss and fragmentation because they have terrestrial and aquatic life stages. One approach to management of pond-breeding species is protection of core upland habitat surrounding the breeding pond. We used genetic variation as an indicator of population status in a common amphibian species, spotted salamanders (Ambystoma maculatum), to determine how amount of suitable upland habitat relates to population status in the greater Charlotte, North Carolina, …

Kentucky Forestry Economic Impact Reports
Kentucky plays a pivotal role in providing forest products to the U.S. and the forestry sector is a major economic force in the Commonwealth providing over 51,000 jobs and $9.9 billion to Kentucky’s economy in 2012. This economic input was generated from 708 facilities located in 109 of Kentucky’s 120 counties including a wide range of industries from logging and sawmills to cabinet manufacturers and paper and producers. In 2012 Kentucky was one of the largest producers of hardwood timber with over 590 million board feet of sawlogs and over 900,000 tons of pulpwood harvested from private family-owned forests. This …
