|
landscape
|
the area of land (or water) that is composed of different communities and ecosystems.
|
|
|
Biomes
|
broad-scale geographic regions with similar geological and climatic conditions, which results in similar plant and animal communities.
|
|
|
ecosystem
|
an environment’s physical conditions and the array of organisms within its boundaries
|
|
|
ecosystem consists of:
|
Biotic: living interactions
Abiotic: nonliving (physical and chemical) interactions There is an exchange of energy and matter |
|
|
Species richness
|
the number of different species contained in a community.
|
|
|
Species evenness
|
the relative abundance of individuals within each of the species in a community.
|
|
|
Species diversity
|
species richness + species evenness in a given area.
|
|
|
Community
|
Populations of different species living and interacting in an area form a community.
|
|
|
Home Range
|
The area over which a species is distributed
|
|
|
habitat
|
The space an individual or population normally occupies
|
|
|
Population
|
a group of interacting individuals of the same species occupying a specific area.
|
|
|
biosphere
|
the thin layer surrounding the Earth that supports all of life.
|
|
|
Population ecology
|
study the study of patterns and processes involving single-species groups of individuals.
|
|
|
Community ecology
|
the study of patterns and processes involving at least two species at a particular location.
|
|
|
biological evolution
|
results from changes in a population’s genetic makeup over time; thus, allowing a species to adapt to its ever-changing environment.
|
|
|
What does it mean for a species to “adapt”?
|
Adapt to the new conditions.
Migrate to an area with more favorable conditions. Die and/or become extinct |
|
|
adaptation
|
any inherited trait that may give an individual and its offspring better chances for survival and reproduction.
|
|
|
species
|
populations of organisms that have a high level of genetic similarity.
|
|
|
island of habitat
|
the most favorable environment or situation in which populations may diverge into distinct species
|
|
|
Heterogeneity
|
the state of being mixed in composition and the uneven distribution of objects across the landscape
|
|
|
composition
|
the number of patch types represented on a landscape and their relative abundance.
|
|
|
structure
|
composition, the configuration, and the proportion of different patches across the landscape
|
|
|
function
|
how each element in the landscape interacts based on its life cycle events.
