transfer
to move from one place to another
transformation
process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria
zonation
the distribution of plants or animals into specific zones according to such parameters as altitude or depth, each characterized by its dominant species.
sucession
The series of predictable changes that occur in a community over time
Gaia Hypothesis
States that the environment on a global level has been changed for the better by life over the history of life on earth.
positive feedback
A type of regulation that responds to a change in conditions by initiating responses that will amplify the change. Takes organism away from a steady state.
negative feedback
A type of regulation that responds to a change in conditions by initiating responses that will counteract the change. Maintains a steady state.
percentage of solar radiation absorbed by the earths surface
71%
indicator species
Species that serve as early warnings that a community or ecosystem is being degraded.
Lincoln Index
a way to measure the abundance of small motile organisms
(catch 1 x catch 2) / marked in catch 2
simple experimental method
the simplest form of research design. In a pre-experiment either a single group or multiple groups are observed subsequent to some agent or treatment presumed to cause change.
organic storage
stores chemicals that are complex carbon compounds
inorganic storage
stores chemicals that do not contain complex carbon compounds
k strategist
reproduce late in life; few offspring; care for offspring
r strategist
reproduce early in life; many small unprotected offspring
size of protected area
The larger the size of the protected area allows for larger populations and gene pools, and a wide variety of species. A round shape is better it doesn't have edges. The less edge creates differences in the structure of an ecosystem. Corridors provide safe passage between protected areas
importance preserving biodiversity
creates a balance of life on our earth. Without it, it would be a very boring place and the balance of nature would also get disturbed.
percent of freshwater on earth
2.6%
colonization
the action or process of settling among and establishing control over the indigenous people of an area (lowest soil fertility)
degradation
a decline to a lower condition, quality, or level
dust bowl overharvesting
reductions in soil conservation measures and the encroachment onto poorer lands made the farming community more vulnerable to wind erosion, soil moisture depletion, depleted soil nutrients, and drought
subsistence
the minimum amount to sustain life
erosion
Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation)
retains the smallest amount of nutrients and minerals
sand
World Heath Organization (WHO)
a United Nations agency to coordinate international health activities and to help governments improve health services
conifer
pine tree (usu. evergreen); cone-bearing tree
soot
black powder in smoke
smoke
the cloud of black, gray, or white gases and dust that is produced by burning something
acid deposition
Sulfur oxides and nitrogen oxides, emitted by burning fossil fuels, enter the atmosphere-where they combine with oxygen and water to form sulfuric acid and nitric acid-and return to Earth's surface
photochemical
interacts with the sun
catalytic converter
exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants
carcinogens
Cancer causing agents
