Ecology chapter 1

Behavior ecology

the study of how birds and mammals do certain behaviors in the wild to either survive or mate.(like dancing for the female)

Aeroecology

the study of the earth atmosphere boundary

urban ecology

it’s the study of how living things survive and interact with the cities.

ecology is driving by

question,observation,temporal and research

paleoecology

(paleo=past)

how ecosystems change over time due to climate, land, and evolution.Understanding how things worked in the past.

levels of ecology (hierarchical )

organism (single living), Population (a group of species), community (diverse species), ecosystem (the organisms plus the physical things in their environment) biosphere (the whole planet)

biotic

The living components like animals humans plants bacteria

Abiotic

The non living parts like the sunlight tempt water and soil.

Robert McArthur

He describes how different type of animals are able to live in the same habitat because they all use the habitat differently. For example for food shelter and resources.

subdisciplines of ecology

population (side and growth), community (interaction), ecosystem (energy nutrients), urban (ecosystem in cities), landscape (patterns across land), and paleoecology (past ecosystems)

question-driven research

focusing on answering important ecological info rather than just getting data. examples (how do species coexist in the same habitat)

natural history

carefully observing organisms in their natural environments .

time

time matter because ecological changes can happen quickly (like population) slowly (climate change evolution).

scale

results differ at small scales (one population) large scales (ecosystems and biomes)
