Exotic Pet Trade
Legal and illegal capture and sale of wild species of plants and animals for huge profits
Habitat Fragmentation
Caused by roads, logging and urban development that reduces large habitats into smaller divided areas
Biodiversity Hot Spot
Areas that are already highly endangered centers of biodiversity
Overexploitation
practice of harvesting or hunting to such a degree that remaining individuals may not be able to replenish the population
Threatened Species
Still abundant in its natural range but is declining in numbers
Invasive Species
Non-native Kudzu plants out-competing local southeastern plants for resources
Indicator Species
Species that serve as early warnings that the ecosystem or community is being degraded
Endangered Species
Has so few individual survivors that the species could soon become extinct
Local Extinction
When a species is no longer found in an area it once inhabited but is found elsewhere in the world
Island Biogeography
Scientists have determined a species-area relationship that a 90% habitat loss causes the extinction of approx.50% of the species in that habitat.
Keystone Species
a species that is critical to the functioning of the ecosystem in which it lives because it affects the survival and abundance of many other species in its community
Indigenous Species
species that originate and live, or occur naturally, in an area or environment.
Habitat Islands
Small patches of habitat surrounded by areas of unsuitable habitat are known as this
Background Extinction
The continuous natural extinction rate of species whic his typically balanced by the formation of new species is known as this
National Wildlife Refuges
Areas that have been set aside for the protection of threatened or endangered species
Hot Spots
Concentrated areas of biodiversity and rare or potentially endangered species
CITES
an international treaty banning the hunting and trade of endangered species
-Created a list of animals in which countries who sign are forced to protect them
Economic Value
the VALUE of an organism, species or ecosustem based on its existence, regardless of its usefeulness to humans is its
Intrinsic Value
value of an organism, species, ecosystem, or the earth's biodiversity based on its existence, regardless of whether it has any usefulness to humans
-Their own right to be able to live and be as they are
Selective Cutting
Type of logging results in intermediate-aged or mature trees in uneven-aged forests cut singly or in small groups
Clear Cutting
Logging results in the maximum profits in the shortest time frame
Strip Cutting
Managed area of uniformly aged trees which are grown until commercially viable
Wilderness Lands
Undeveloped lands that have been set aside as reserves by being roadless are limited to hikers and campers that can visit but cannot stay
Biosphere Reserves
Areas set up with a protected inner core for wildlife surrounded by more multiuse buffer zones
Biodiversity Hot Spot
Areas identified by conservation biologists as having high plant diversity and/or where ecological services are being impaired
Second-growth forests
areas where cutting has occurred and a new, younger forest has arisen.
Old-growth Forests
Forests which have reached climax community and is relatively undisturbed
Surface Fires
Fires that burn away flammable ground material and help prevent more destructive fires
Reconciliation Ecology
The new science which focuses on maintaining habitats and biodiversity in places shared with human activities instead of as separate reserves
HIPPCO
Habitat destruction, Invasive Species, Population growth, Pollution, Climate Change, Overexploitations
Endangered Species Act 1973
Designed to identify and protect endangered species in the United States
Habitat Fragmentation
is when large areas of habitat are divided typically by roads, crop fields or projects
-blocks animals migration routes
-animals are more vulnerable to die because of the small, inclosed space
Rangelands
are unfenced grasslands in temperate and tropical climates that supply forage or vegetation for grazing
