|
|
Term

Definition
the area of land (or water)
that is composed of different communities
and ecosystems
– At this level, communities and ecosystems are
linked by the dispersal of organisms and the
exchange of materials |

Definition
geographic regions with similar
geological and climatic conditions
Study: patterns of diversity |
|
|
Term
|
Definition
examines natural patterns across the landscape
– The relationship between two or more variables is
studied
– The results suggest a relationship but do not prove
cause and effect |

Definition
test under controlled conditions and controls the
independent variable in a predetermined way
(In a lab, is very controlled, can't be directly applied) |
|
|
Term
|
Definition
Test applied to natural setting
(difficult to control other influencing factors, but results are realistic) |

|
Term
|
Definition
decrease in air temperature through expansion rather than
through heat loss. Depends on moisture in air. Causes mountain shadow effect |
|
|
Term
|
Definition
| the deflection in the pattern of air flow due to differences in rotation speed (Santa example) Creates air cells and belts |
|
|
Term

|
|
Term
|
Definition
| the change in allele frequency due to random chance associated with sexual reproduction |
|
|
Term
|
Definition
a measurable, gradual change over a
geographic region in the average of a phenotypic
trait |
|
|
Term
|
Definition
a population adapted to its unique
(often abrupt) local environmental conditions |
|
|
Term
|
Definition
the process in which one
species gives rise to multiple species that exploit
different features of an environment (food,
habitat) |
|
|
Term
|
Definition
the ability of the genotype to give rise to different phenotypes under different environmental conditions.
2 types: developmental (irreversible, reallocation of biomass during growth) and Acclimation (reversible, individual's response to change) |
|
