Description

This flexible laboratory manual contains nearly 60 exercises involving small-scale ecological systems that can be conducted within a weekly lab period right on campus, regardless of weather or resources available. Each chapter explains a fundamental concept, and then gives three separate hands-on exercises that can involve outdoor observation and measurements on campus, laboratory systems, library research, biological collections, or computer resources.

Additionally, calculation pages accompanying each lab walk students through standard mathematical modeling or statistical tools commonly used by ecologists to address the question at hand, building students’ quantitative and critical thinking skills. All calculations and statistical analyses can be completed by students using simple calculators.
