Position of the continents
Population ecology only deals with declining populations that are in need of intervention in order to survive.
Population ecology focuses on individuals and their interactions, but not the abiotic environment.
Population ecology attempts to explain how and why the number of individuals in a given area changes over time.
Population ecology is not important to scientists in applied disciplines, such as wildlife management.
When one tectonic plate slides underneath another.
Due to mining activities.
Because of the Coriolis effect.
On the leeward side of a mountain.
Buildings and paved roads don’t absorb water, so run off is significantly greater in developed areas
Precipitation is usually greater in urbanized areas than in natural areas due to heat islands.
Urbanized areas are almost always built on floodplains and hence are more prone to flooding.
Most urban areas don’t have adequate sewer systems to handle the rain.
Change in species occurring in transitional zones between communities.
number and variety of ecosystems in the biosphere.
Environmental benefits species provide in a community.
Number of different ecosystem services.
Number and variety of Earth’s organisms.

the study of human-designed communities.
The study of the influences of pollution on natural ecosystems.
A science exclusively concerned with terrestrial ecosystems.
The study of the connections among various ecosystems.

Extinction is the elimination of a species from Earth.
Background extinction eradicates a large number of species during a relative short period of geologic time.
Mass extinctions have occurred 5-6 times throughout Earth’s history.
Extinction rates are accelerated by human activities.
The present extinction rate is 100-1,000 times the background rate.

fewer insects and weeds developing resistance to pesticides.
More insects and weeds developing resistance to pesticides.
More beneficial microorganisms in the soil
More biodiversity of fish and other aquatic organisms not affected by the pesticides.
Farmers applying progressively smaller quantities of pesticides.
An enhanced greenhouse effect.
Because it is an island buffered by ocean water.
The ocean conveyor belt
Domestic and municipal use
It is released when fossil fuels are burned.
It is part of the carbon cycle, which is also known as the greenhouse cycle.
It can absorb infrared radiation.
It is responsible for protecting organisms from UV radiation.
Fossil fuel emissions are not responsible for the enhanced greenhouse effect.
Greenhouse gases remain in the atmosphere for many years.
Deforestation must also be stopped in order for temperatures to decline.
Increased methane emissions will more than make up for the difference.
