Chapter 43 Flashcards
Name the 6 subfields of ecology
Organism, Population, Community, Ecosystem, Biome, Biosphere
What is the definition of ecology
Scientific study of the interactions between organisms and the environment.
What is organismal ecology
An organisms structure, physiology, and behavior. How they meet the challenges posed by the environment.
How do humpback whales choose their calling grounds is an example of what subfield of ecology
Organismal
What is population ecology
The factors that affect how many individuals of a particular species live in an area.
What environmental factors affect reproduction rates in deer mice is an example of what subfield of ecology
Population ecology
What is community ecology
How different species interact with each other
What factors influence diversity of species that make up a forest is an example of what subfield of ecology
Community ecology
What is ecosystem ecology
Emphasizes energy flow and chemical cycling among the various biotic and abiotic components.
How will our ecosystem be affected by climate change is an example of what ecology subfield
Ecosystem.
What is landscape ecology
Focuses on factors controlling exchanges of energy, materials, and organisms across multiple ecosystems.
How do trees lining drainage channels serve as corridors of dispersal of forest animals? What subfield
Landscape
What is biosphere ecology
Examines how the regional exchange of energy and materials influences the functioning and distribution of organisms across the biosphere.
What are three types of biotic components in an environment
Interactions with other species, predation, competition.
Why does temperature affect organism distribution
It affects biological processes.
What are six abiotic factors in the environment
Temperature, Water and Oxygen availability, salinity, sunlight, wind, soil.
What is a climate
The prevailing weather conditions in an area.
What is adiabatic cooling
For every 1000 m increase in elevation, the temp drops 10 degrees celsius.
What is a rain shadow
Warm moist air flows up mountain and cools releasing precipitation, leeward side allows drier air to descend.
What is an oligotrophic lake
High in elevation, low amount of nutrients.
What are different flora and fauna the result of
independent evolution of separate unconnected populations.
Name the 6 major biogeographic regions
Nearctic, Palearctic, Neotropical, Ethiopian, Oriental, Australian
What divides the biogeographical regions
Oceans, himalayas, the sahara desert.
