Ecology and Environmental Problem Solving
EVST 262a

Introduction

The course covers two main themes. The first is the presentation of basic scientific knowledge in ecology. The second theme is the application of knowledge to the task of environmental conservation. Students will learn how to apply current knowledge to topical issues and how to adapt that knowledge to solving emerging new problems that may be confronted in the future.

The course will give students a fundamental mechanistic understanding about the way biotic (e.g., resources, competitors, predators) and abiotic (e.g., climate) determine pattern in the distribution and abundance of species. Students will learn how individuals within a species cope with changing environmental conditions by altering their behavior, by making physiological adjustments and changing the allocation of resources among survival growth and reproduction. Students will learn how to scale this mechanistic detail to the level of population demography in order to understand the consequences for long-term population viability. Populations of species coexist within communities and species interactions within communities can lead to highly complex and nonlinear dynamics. Students will gain an appreciation for the way effects of perturbations propagate within food webs. They will also begin to appreciate and learn to forecast the myriad direct and indirect effects that can be realized following perturbations. Students will then be shown how ecologists use this scientific insight to deal with emerging environmental problems such as protecting biodiversity, understanding the consequences of habitat loss on species diversity, forecasting the effects of global climate change on species population viability and geographic distribution.
