What are the 5 types of ecology? - organismal, population, community, global, and
ecosystem
What is organismal ecology? - studies a single organism and how it interacts with
its environment
ex: salmon, study how interact with organisms in and around the stream
What is population ecology? - Studying how the number and distribution of
individuals in a population change over time
What is community ecology? - The nature of interactions between species and the
consequences of those interactions
What is ecosystem ecology? - study how the nutrients and energy move among
organisms and through the surrounding atmosphere and soil or water. (includes
abiotic factors)
What is global ecology? - Quantify the effects of human impact on the biosphere.
What is conservation biology? - the effort to study, preserve, and restore threatened
genetic diversity in populations, species diversity in communities, and ecosystem
function
What are the abiotic factors that determine the distribution of organisms? -
temperature, moisture regime, salinity, water depth, flow regime in water.
, What is a niche? - The range of conditions that a species can tolerate and the range
of resources it can use.
What are the biotic factors that determine the distribution of organisms? -
Competition, parasites, disease, habitat (like the yucca plant for the yucca moths-
use them to lay eggs)
What is the Wallace line? - It is a trench in the ocean that separates species with
Asian and Australian affinities, biological demarcation.
Why is temperature a particularly important abiotic factor? - It is important in
determining the range of a species because it has a huge impact on the physiology
of organisms, they are limited in their ability to regulate body temperature
What is the difference between weather and climate? - Climate is the LONG
TERM weather conditions in an area, while weather in the SHORT TERM
conditions of temperature, precipitation, sunlight, and wind.
Why are the tropics warm and the poles cold? - Because of the angles of the sun,
areas near the equator get way more sunlight per unit area than the poles. And the
sun strikes at lower angles at the poles, much less energy is received per unit area.
Why are the tropics wet? - Hadley cells allow for the flow of air, and warmer air
from the tropics holds more water, as the air cools/rises it produces rain. Band of
deserts at around 30 latitude
What is the Coriolis effect? - The spinning of the earth on it's axis causes it, it
makes the air and water in the northern hemisphere move clockwise, and counter
clockwise in the Southern Hemisphere.
