BIOL 203
Ecology Fall 2021
Division III Quantative/Formal Reasoning
Cross-listed ENVI 203 / BIOL 203

Class Details

This course combines lectures & discussion with field and indoor laboratory exercises to explore factors that determine the distribution and abundance of plants and animals in natural systems. The course begins with an overview of global environmental patterns and then builds from the population to ecosystem level. Throughout the course, we will emphasize the connection between basic ecological principles and current environmental issues. Selected topics include population dynamics (competition, predation, mutualism); community interactions (succession, food chains and diversity) and ecosystem function (biogeochemical cycles, energy flow). Laboratory activities are designed to help students build skills in data analysis and scientific writing.
The Class: Format: lecture/laboratory; Six hours per week. Students will view pre-class lecture videos; class meetings will focus on discussion, synthesis, and application of course content.
