Chapter 52-An Introduction to Ecology and the Biosphere
Define Global ecology, Landscape ecology, Ecosystem ecology, Community ecology, Population
ecology, Organismal ecology,
Earth’s climate : Macroclimate, Microclimate, Global Climate Patterns, Global Air Circulation and
Regional and Local Effects on Climate: seasonality, large bodies of water, and mountains.
The structure and distribution of terrestrial biomes are controlled by climate and disturbance: Climate and
Aquatic biomes are diverse and dynamic systems that cover most of Earth: Zonation in Aquatic Biomes,
Seasonal turnover in lakes, aquatic biomes.
Chapter 53- Population Ecology
population density, dispersion- patterns of dispersion,, and demographics-life table, cohort, Survivorship
Curves, Reproductive Rates, reproductive table; Type I, Type II, and Type III Evolution and Life History
Diversity- semelparity, iteroparity, ‘trade-offs” and Life Histories.
The exponential model describing population growth in an idealized, unlimited environment, Exponential
Growth, logistic population growth, Carrying capacity
Factors that regulate population growth are density dependent, Population Dynamics, Regional Patterns
of Population Change,
Chapter 54- Community Ecology
Interspecific interactions: competition, predation, herbi vory, symbiosis (parasitism, mutualism, and
Competition: define ecological niche, competitive exclusion, Resource partitioning. Fundamental niche,
Realized niche of any species. Character Displacement and its importance.
Predation: feeding adaptations, defensive adaptations, Behavioral defenses, morphological and
physiological defense adaptations. Cryptic coloration, aposematic coloration, Batesian mimicry,
Symbiosis: Parasitism, Mutualism: Obligate and Facultative mutualism.
Diversity and trophic structure characterize biological communities: Species Diversity, trophic structure,
food web, Limits on Food Chain Length: energetic hypothesis, dynamic stability hypothesis. Species with
a Large Impact: Dominant species, Invasive species, Keystone species, Foundation species (ecosystem
