Ecology: History, Scope and Branches
This historical LBFL Ecology address is preserved for learners, bookmarks, and external references. The current ten-lecture Ecology course now develops these foundations in Lecture 01.
Ecology examines how organisms interact with one another and with physical factors such as temperature, water, light, soil, salinity, nutrients, and disturbance. Its major levels of organization include organism, population, community, ecosystem, landscape, biome, and biosphere. Modern ecology also connects closely with physiology, evolution, genetics, climatology, geology, geography, statistics, GIS, conservation, and environmental management.
The historical development of ecology moved from descriptive natural history toward hypothesis-driven, experimental, quantitative, spatial, and systems-based approaches. Concepts such as population regulation, species interactions, energy flow, nutrient cycling, ecological succession, biodiversity, and ecosystem management remain central to the subject.
For the current course sequence, continue with Lecture 01: Foundations of Ecology — History, Scope and Levels of Organization.
