Chapter 52 Flashcards
Ecology roots
oikos - home
logos - study
Examples of naturalist
Aristotle and Darwin, they studied living world and systematically recorded their observations
How is modern ecology viewed differently from the past
Its more than just observation, now more rigorous, needs biological knowledge
Biosphere
Global ecosystem of all the planets of landscapes
Global ecology
How exchange of energy and materials influence the distribution of organisms around the biosphere
Landscape ecology
- Factors controlling energy exchange
- Materials
- Organisms
Ecosystem Ecology
Ecosystem ecology emphasizes energy flow/chemical cycle between organisms and environments
Ecosystem
Community of organisms in an area
Population Ecology
Pop. - group of species living in the same area
Analyzes factors that affect size + how/why it changes over time
Organismal Ecology
Sub disciplines of physiology, evolutionary, and behavioral ecology.
ex. How do hammerhead sharks select a mate?
Tropics
-23.5° North/South Latitude
¸Why is it hotter closer to equator?
- Sunlight hits area more directly causes more heat/ light per unit of surface area
- Higher latitudes - sunlight hits earth at an oblique angle
What are global climate patterns largely determined by
Input of Solar Energy
Earth’s movment in space
Other influential Climate factors
Seasonal Variation in Climate
Bodies of water
Mountain Ranges
Where are seasonal cycles more obvious?
Higher latitude
What alters ocean currents?
Seasonal changes in wind patterns
Result of changing ocean currents?
Upwelling of cold water from deep ocean layers, which are nutrient rich.
Biome
Any of the world’s major ecosystem types, determined by vegetation type or physical environment in aquatic biomes. Ex. Desert
Climograph
Plot of the temperature and precipitation in a particular region
What has a strong influence ion the distribution of planmt species
Climate, a major factor in determining location of terrestrial biomes
Temperate broad leaf forest
a biome located throughout midlatitude region where there is sufficient moisture to support the growth of large, broadleaf deciduous trees.
