Study Notes

Introduction to Ecology

Ecology is the study of the abundance and distribution of organisms as shaped by environmental factors.
Ecologists are interested in how biotic and abiotic factors influence the abundance and distribution of organisms.

Environmental Factors

Abiotic factors: precipitation, sunlight, nutrients, weather patterns
Biotic factors: predators, prey, mutualists, parasites, mates, any living organism that can influence other living organisms

Scales of Organization

Organismal ecology (physiological ecology): how physiological processes of an organism dictate its distribution and abundance
Population ecology: study of multiple individuals of the same species living in a location
Community ecology: study of all species that live close enough in a location to interact
Ecosystem ecology: study of living members of the community and abiotic components that interact with them
Biosphere: the collection of all biomes on the planet

Community Ecology

Study of interactions between species that live in a community and how these interactions affect their distribution and abundance
Includes competition, predation, and symbiosis (mutualism and parasitism)
Diversity depends on survival of species and their relative abundance

Ecosystem Ecology

Includes the water cycle, carbon cycle, nitrogen cycle, fire, and any abiotic factor that affects the community
Carbon cycle: carbon is a molecule that exists in different forms, is contained in living organisms, and is returned to the soil when they die

Biomes

Dictated by precipitation and temperature
Examples: rocky intertidal, poles, and other geographical areas

Rocky Intertidal

A biome or environment for species to live in, characterized by tides (high/upper, mid, and low)
Species that live here are adapted to live in both water and land
Examples: species that live in the tidal area near the ocean
