Association Between Fire Return Interval And Population Dynamics In Four California Populations Of Tecate Cypress (Cupressus Forbesii), Roland C. De Gouvenain, Ali M. Ansary Dec 2006

Association Between Fire Return Interval And Population Dynamics In Four California Populations Of Tecate Cypress (Cupressus Forbesii), Roland C. De Gouvenain, Ali M. Ansary

Faculty Publications

The Tecate cypress (Cupressus forbesii) is a tree species associated with chaparral ecosystems in southern California and northern Baja California, Mexico. It is fire-adapted, its regeneration triggered by the opening of serotinous cones when adult trees are burned. Surveys made in the 1980s by others suggested that some Tecate cypress populations were declining, and some authors suggested that increased fire frequency in southern California was a major factor for this decline. We asked whether current population trends were still negative for Tecate cypress 20 years later, and whether population growth was associated with fire return interval length. Based on demographic, …

Using Student Generated Qualitative Ecological Models, J. Scott Blackwood, Marion Dresner, Hang-Kwang Luh Jan 2006

Using Student Generated Qualitative Ecological Models, J. Scott Blackwood, Marion Dresner, Hang-Kwang Luh

Environmental Science and Management Faculty Publications and Presentations

In this activity, students construct qualitative models of an ecosystem and use the models to gain a better understanding of direct and indirect ecological interactions. Qualitative modeling is described for use in two procedures, each with different educational goals and student backgrounds in mind. Part 1 is designed with the non-major or beginning ecology student in mind, and is intended both to improve student understanding of the ecosystem of interest and to provide a framework for the instructor to assess student learning. Part 2 is designed for more advanced students of ecology and involves the use of modeling software (POWERPLAY) …
