Study Guide 2

Front 1

Describe the relationship between ecology and evolutionary biology

Back 1

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.

Front 2

Distinguish between abiotic and biotic components of the environement

Back 2

Abiotic are nonliving and biotic are living

Front 3

Clarify the difference between ecology and environmentalism

Back 3

Ecology is how organisms interact with their environment while environmentalism is advocating the protection of nature

Front 4

Describe the problems caused by introduced species and illustrate with a specific example

Back 4

They mess up the food web. For example rats were introduced on anacapa island and they eat the bald eagle eggs.

Front 5

Describe, with examples, how biotic and abiotic factors may affect the distribution of organisms

Back 5

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

Front 6

List four abiotic factors that are the most important components of climate.

Back 6

Temperature
Water
Salinity
Sunlight
Rocks and soil

Front 7

Distingusih between macroclimate and microclimate

Back 7

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.

Front 8

Explain, with examples, how a body of water and a mountain range might affect regional climatic conditions.

Back 8

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.

Front 9

Explain how an ecologist might predict the effect of global warming on distribution of a tree species

Back 9

Some areas where there wasnt plant growth before is now occuring because of the climate shift

Front 10

Describe three factors that affect (determine) climate.

Back 10

bodys of water
Mountains
Seasonality

Front 11

Define: Seasonal turnover

Back 11

The mixing of waters as a result of changing water-temperature profiles in a lake.

Front 12

Define: thermocline

Back 12

A narrow stratum of rapid temperature change in the ocean and in many temperate-zone lakes.

Front 13

Define: photic zone

Back 13

The narrow top slice of the ocean, where light permeates sufficiently for photosynthesis to occur.
