Monster Seminar JAM - How valuable is a patchy resource?
Dr. Danny Grunbaum, School of Oceanography, University of Washington
Many issues in both applied and basic marine ecology boil down to the question: How quickly and accurately do organisms locate and exploit the most favorable subsets of their environments? My colleagues and I are attempting to address this question by making detailed quantitative observations of movement behaviors in a variety of organisms, and incorporating those observations into population-level models of abundance and distribution. From these models, we can derive summary statistics that we hope indicate which ecological situations share key dynamic characteristics. In this talk, I will focus on consumer-resource interactions as an example to illustrate transitions from observation to model to ecological index. The end result in this case is an estimate of effective availability of patchy resources to specific types of consumers. I will conclude by speculating on potential applications of related ideas to conservation and management.
