-
captive breeding
the breeding of rare or endangered wildlife in controlled settings to increase the poulation size
-
restoration ecology
the renewal of degraded or destroyed ecosystems through acticve human intervention
-
bioaugmentation
- the use of organisms to add essential nutrients to depleted soils
- eg. clovers are planted to replenish nitrogen levels in soil
-
succession
- the series of changes in an ecosystem that occurs over time, following a disturbance
- usually benefits many species
-
invasive species
- a species that can take over the habitat of native species or invade their bodies
- e.g. zebra mussels
- they can outcompete native mussels for resouces, have no natural predators, and can grow exponentially
-
alien species
- a species that is accidentally or deliberately introduced to a new location
- e.g. round gobies
-
bioremediation
- the use of living organisms to clean up contaminated areas naturally
- -certain plants are grown in certain areas to clean the soil by collecting the poisins
-
overexploitation
the use or extraction of a resource until it is depleted.
-
biodiversity hotspot
- a place where there is an exceptionally large number of species in a relatively small area
- e.g. Carolinian Canada and Leitrim Wetlands
-
keystone species
- a species that can greatly affect population numbers and the health of an ecosystem
- e.g. sea otters
-
Biodiversity
the number and variety of organisms found in a specific region as well as all the number and variety of ecosystems within and beyond that region
-
protect
To legally guard from harm a species that is listed as endangered,threatened or of special concern.
-
biodiversity crisis
the current accelerated rate of extinctinons
-
extinction
the death of all the individuals of a species
-
ecosystem engineer
- a species that causes such dramatic changes to landscapes that it creates a new ecosystem
- e.g. The beetles in the desert of Mexico
-
biocontrol
the use of a species to control the population growth or spread of an undesirable species
-
deforestation
the practice of clearing forest for logging or other human uses, and never replanting them
-
habitat loss
the destruction of habitats which usually results from human activities, or perhaps natural disasters
-
dominant species
- a species that is so abundant that it has the biggest biomass of any community member
- e.g. American Chestnut
-
reforestation
the regrowth of a forest, either through the planting of seeds or trees in an area where a forest was cut down
-
community
all the populations of the different species that interact in a specific area or ecosystem
