Explain the factors contributing to the characteristics of terrestrial biomes

Describe the eight major terrestrial biomes

Ecology

the study of the interactions of organisms with their environments

Biosphere

One of the first to perceive the global dangers of pesticide abuse

have a profound effect on regional climates by warming or cooling coastal areas; they are created by winds, planet rotation, unequal heating of surface water, and location and shapes of continents.

A group of individuals of a single species that occupy the same general area

Interactions between biotic and abiotic factors

number of individuals of a species per unit area or volume

the way individuals are spaced within their area; can be clumped, random, uniform

track survivorship over the life span of individuals in a population

plot the proportion of individuals alive at each age; type I, type II and type III

The rate of population increases under ideal conditions;

Calculated using the equation

G = rN

r - selective traits

k- selective traits

How much you can take out of a population without causing population decline

Human population is expected to continue increasing for several decades

An assemblage of populations living close enough together for potential interaction

A pattern of feeding relationships consisting of several different levels

Sequence of food transfer up the trophic levels

A network of interconnecting food chains ; true food chains are not as neat as a straight line; instead they are more complex. 

A species whose impact on its community is larger than its biomass or abundance indicates; occupies a niche that hold the rest of the community in place

is the amount of solar energy converted to chemical energy by an ecosystem’s producers for a given area and during a given time period

NET

primary production is the amount of biomass minus the amount used by the producers for their own cellular respiration.

the amount of living organic material in an ecosystem.

where a chemical accumulates or is stockpiled outside of living organisms.

One that is "in danger of extinction throughout all or a significant portion of its range"

Those likely to become endangered in the foreseeable future

loss of a single population of a species.

Altering phenotype in response to environmental conditions

Application of ecological principles to the study of the structure and dynamics of a collection of ecosystems

"overpasses" and underpasses that allow movement of animals

Have a large number of endangered and threatened species; endemic species

Extensive region of land with one or more areas undisturbed by humans

sustainable development

zone reserve contributes to this;

Long-term prosperity of human societies and the ecosystems

Uses ecological principles to restore environments
