Genetic Diversity And Camptothecin Variation In Camptotheca Decaisne, Yuiie Wang Jul 2001

Genetic Diversity And Camptothecin Variation In Camptotheca Decaisne, Yuiie Wang

Electronic Theses and Dissertations

Camptotheca Decaisne is the major source of the promising anti-cancer alkaloids camptothecins. The main objectives of this study are (1) to reveal the genetic diversity of Camptotheca and to identify taxa with RAPD markers; (2) to determine the camptothecin (CPT) variations within and among different populations and taxa, with tissues, season, and age; and (3) to determine the effects of environmental stress on the camptothecin production in Camptotheca. RAPD markers provide a powerful tool for the identification of some populations (particularly cultivars) and the detection of genetic variation within Camptotheca. Three primers (OPA02, OPA03, and OPA04), generating 44 polymorphic bands …

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 …
