Describe the relationship between ecology and evolutionary biology
|
Ecology is the study of the interactions between and among species and their environemnt that govern their abundance and distrabution.
Events that occur in ecological time affect life in evolutionary time. |
|
Distinguish between abiotic and biotic components of the environement
|
Abiotic are nonliving and biotic are living
|
|
Clarify the difference between ecology and environmentalism
|
Ecology is how organisms interact with their environment while environmentalism is advocating the protection of nature
|
|
Describe the problems caused by introduced species and illustrate with a specific example
|
They mess up the food web. For example rats were introduced on anacapa island and they eat the bald eagle eggs.
|
|
Describe, with examples, how biotic and abiotic factors may affect the distribution of organisms
|
Biotic factors include food for animals. Seaweeds and algae make sea urchins appear.
Abiotic facrots include temperature, water, and salinity. Organisms may avoid these conditions |
|
List four abiotic factors that are the most important components of climate.
|
Temperature
Water Salinity Sunlight Rocks and soil |
|
Distingusih between macroclimate and microclimate
|
Macroclimate are paterns on the global, regional and local level.
microclimate are very fine patterns, such as those encountered by the community of organisms that beneath a fallen log. |
|
Explain, with examples, how a body of water and a mountain range might affect regional climatic conditions.
|
As moist air moves in off the ocean and encounters mountains, it flows upward, cools at higher altitude, and drops a large amount of water as precipitation.
|
|
Explain how an ecologist might predict the effect of global warming on distribution of a tree species
|
Some areas where there wasnt plant growth before is now occuring because of the climate shift
|
|
Describe three factors that affect (determine) climate.
|
bodys of water
Mountains Seasonality |
|
Define: Seasonal turnover
|
The mixing of waters as a result of changing water-temperature profiles in a lake.
|
|
Define: thermocline
|
A narrow stratum of rapid temperature change in the ocean and in many temperate-zone lakes.
|
|
Define: photic zone
|
The narrow top slice of the ocean, where light permeates sufficiently for photosynthesis to occur.
