Eco Evo Exam 4(c.22)

Definitions

TermDefinition
Landscape ecology The field of study that considers the spatial arrangement of habitats at different scales and examines how they influence individuals, populations, communities, and ecosystems.
Legacy effect A long-lasting influence of historical processes on the current ecology of an area.
Local diversity The number of species in a relatively small area of homogeneous habitat, such as a stream. Also known as Alpha diversity.
Regional diversity The number of species in all of the habitats that comprise a large geographic area. Also known as Gamma diversity.
Beta diversity The number of species that differ in occurrence between two habitats.
Regional species pool The collection of species that occurs within a region.
Species sorting The process of sorting species in the regional pool among localities according to their adaptations and interactions.
Species-area curve A graphical relationship in which increases in area (A) are associated with increases in the number of species (S).
Species accumulation curve A graph of the number of species observed in relation to the number of individuals sampled.
Stepping stones Small intervening habitat patches that dispersing organisms can use to move between large favorable habitats.
Equilibrium theory of island biogeography A theory stating that the number of species on an island reflects a balance between the colonization of new species and the extinction of existing species.
Potential evapotranspiration (PET) The amount of water that could be evaporated from the soil and transpired by plants, given the average temperature and humidity.
Energy-diversity hypothesis A hypothesis that sites with higher amounts of energy are able to support more species.
Continental drift The movement of landmasses across the surface of Earth.
Pangaea The single landmass that existed on Earth about 250 Mya and subsequently split into Laurasia and Gondwana.
Laurasia The northern landmass that separated from Pangaea about 150 Mya and subsequently split into North America, Europe, and Asia.
Gondwana The southern landmass that separated from Pangaea about 150 Mya and subsequently split into South America, Africa, Antarctica, Australia, and India.
Nearctic region The biogeographic region of the Northern Hemisphere that roughly corresponds to North America.
Palearctic region The biogeographic region of the Northern Hemisphere that corresponds to Eurasia.
Neotropical region The biogeographic region of the Southern Hemisphere that corresponds to South America.
Afrotropical region The biuogeographic region of the Southern Hemisphere that corresponds to most of Africa. Also known as Ethiopian region.
Indomalayan region The biogeographic region of the Southern Hemisphere that corresponds to India and Southeast Asia. Also known as Oriental region.
Australasian region The biogeographic region of the Southern Hemisphere that corresponds to Australia, New Zealand, and New Guinea.
