Determining Differences In The Spatial Distribution Of Forest Structure On The Kaibab Plateau: Implications For Forest Management And The Northern Goshawk, Ryan S. Miller Apr 2001

Determining Differences In The Spatial Distribution Of Forest Structure On The Kaibab Plateau: Implications For Forest Management And The Northern Goshawk, Ryan S. Miller

Other Publications in Wildlife Management

The Kaibab Plateau, in North Central Arizona, has undergone extensive change in the last 100 years due to land management practices such as logging, road building, and fire suppression. The northern goshawk (Accipiter gentilis) has been a center of controversy, due to the potential effects of silvicultural practices on goshawk breeding habitat (Reynolds-1983, Bloom et al 1986, Kennedy 1989, Crocker-Bedford 1990). Current and past research efforts on the Kaibab Plateau have mapped Goshawk nesting territories and temporal change in nesting behavior and success. However, these research efforts have not determined how long-term spatial changes in land-use activities that have influenced …


The Chainsaw And The White Oak: From Astrobiology To Environmental Sustainability, Leo R. Finkenbinder, Dwight E. Neuenschwander Apr 2001

The Chainsaw And The White Oak: From Astrobiology To Environmental Sustainability, Leo R. Finkenbinder, Dwight E. Neuenschwander

Faculty Scholarship – Biology

An American biology professor befriends a Costa Rican farmer who through their relationship stops farming and forest clearing to establish a tourist and research center devoted to saving the country's cloud forest. The Chacon family's experience provides a studied model of sustainability, known in environmental circles as the "White Oak Model."

The Unusual Life History Of Alseis Blackiana: A Shade-Persistent Pioneer Tree?, J. W. Dalling, K. Winter, J. D. Nason, S. P. Hubbell, D. A. Murawski, J. L. Hamrick

Classifications of tree species into regeneration guilds or functional groups are often based on a limited number of life history characteristics indicative of requirements for early establishment, with the assumption that these traits are correlated with growth requirements of larger individuals. We tested the validity of this assumption for Alseis blackiana, a common canopy tree in central Panama, by examining its seed germination, seedling growth, and sapling distribution, growth, and mortality. We found that the early life history of Alseis is characteristic of pioneer species: the seed germination rate was much higher in forest gaps than in the forest understory, …
