    Study Notes

    Definition of Ecology

    • Ecology is the study of interactions between organisms and their environment.

    Scales of Ecological Study

    • Ecology is studied at multiple scales:
      • Individuals: Focus on physiological and behavioral adaptations for survival.
      • Populations: Examines how environmental factors regulate species abundance.
      • Interactions: Investigates the impact of species interactions, e.g., Abert’s squirrels and oak seed dispersal.
      • Communities: Studies how diet choices influence species interactions, such as large herbivores in the Ethiopian Highlands.
      • Ecosystems: Analyzes effects of disturbances, like fires, on community composition and ecological succession, exemplified by the Grand Canyon.
      • Landscapes: Looks at material, energy, and organism exchanges across ecosystems, emphasizing biome heterogeneity.
      • Regions: Explores geographical ecology and the impact of historical climate shifts on current biome distributions, particularly following the Ice Age.
      • Biosphere: Engages with global ecosystem interactions, especially regarding the effects of greenhouse gas concentration changes on diverse ecosystems.

    Historical Perspective on Ecological Ideas

    • Before formal ecology studies, humans inferred ecological concepts through observation during activities like hunting, gathering, and early agriculture.

    Origin of the Term 'Ecology'

    • The term "ecology" was introduced by Ernst Haeckel, a German zoologist, in the 1800s.
