Education:
B.S., Humboldt State College, Wildlife Management, 1967; M.S., South Dakota State University, Wildlife Management, 1969; Ph.D., University of Arizona, Range Management, 1981.

Current Research:
On-going research involves (1) effects of streamside management zone width and age of adjacent pine plantations on small mammals and birds within the Interior Highlands of Arkansas; and (2) effects of even- and uneven-aged management on habitat, birds, small mammals, amphibians, reptiles, and bats. Planned research includes effects of group selection harvesting on Neotropical migratory birds (including nesting success) and effects of pine-bluestem restoration on herpetofauna, butterflies, moths, and nectar plants. (Problem Areas 1 and 3)

Collaborative Research:
Impacts of alternative silvicultural systems and practices (e.g., prescribed burning and retention of streamside management zones) on wildlife (birds, small mammals, amphibians, reptiles, and bats).

Current Research:
My current research focuses on the ecology, behavior, and habitat use of primary cavity-nesting birds. Most research efforts are currently focused on the red-cockaded and pileated woodpeckers. It is important to determine the species of fungi, extent of decay, and other special characteristics of trees used by woodpeckers for their nesting and roosting sites. My research also emphasizes population dynamics of snags used by woodpeckers for both nesting and foraging, and inoculation of pines and hardwoods with heartwood decaying fungi to create suitable decay conditions necessary for woodpecker cavity excavation. During the past 15 years I have studied relationships between southern pine beetles and red-cockaded woodpeckers to determine why bark beetles tend to infest active woodpecker cavity trees. My research efforts also include the ecology and habitat use of Louisiana pine snakes and timber rattlesnakes. (Problem Areas 2 and 4)

Collaborative Research:
We formed an interdisciplinary team to investigate the major losses of red-cockaded woodpecker cavity trees to single-tree infestations of southern pine beetles. Our goal is to determine why losses have increased in the recent past and develop techniques to reduce or eliminate such losses in the future. During the past five years up to 40% of the active cavity trees on some national forests have been lost to southern pine beetle infestation annually. Clearly, such losses cannot be sustained for much longer.

Education:
Ph.D., Texas Tech University, Zoology, 1980

Current Research:
Current research involves the ecology of red-cockaded woodpeckers, snakes, and lepidopteran communities. The interaction of these taxa with fire regimes, especially in southeastern pine communities is of particular interest. (Problem Areas 2 and 4)

Collaborative Research:
Same as above plus the interaction of red-cockaded woodpeckers, southern pine beetles, and woodpecker cavity trees. The Crosscutting Theme "Sustainability and Productivity of Southern Pine Ecosystems" covers these collaborative interests.

Education:
B.S., Stephen F. Austin State University, Biology; M.S., Stephen F. Austin State University, Biology; Ph.D., Texas A&M University, Wildlife and Fisheries Sciences

Current Research:
My research focuses primarily on basic amphibian ecology and the impacts of forest management practices on amphibian communities. The long-range goals of my research are (1) to determine the impacts of various forest management practices (including fragmentation) on amphibians, (2) to determine likely consequences of climatic changes on amphibians, (3) to develop guidelines for managing southern forest ecosystems to ensure healthy populations of amphibians, (4) to develop and evaluate alternative monitoring protocols for amphibians, and (5) to develop and validate predictive habitat relationship models for amphibians.

Collaborative Research:
My collaborative research focuses primarily on the ecology, behavior, and habitat use of the red-cockaded woodpecker.
