-
-
The number and variety of organisms found in a specific region
E.g. in a forest there are birds, wolves, hare, etc.
-
-
To legally guard from harm a species that is listed as endangered, threatened, or of special concern
E.g. to make sure no one hunts an endangered species like the giant panda
-
-
A place where there is an exceptionally large number of species in a relatively small area
E.g. somewhere that has 20 different species is a biodiversity hotspot as opposed to somewhere that only has 5
-
-
All the populations of different species that interact in a specific area or ecosystem
E.g. symbiosis: mutualism, competition & parasitism
-
-
A species that is so abundant that it has the biggest biomass of any community member
E.g. more hare population than any other species
-
-
A species that can greatly affect population numbers and the health of an ecosystem
E.g. if hare are wiped out, then wolves have no food, etc.
-
-
The breeding of a rare or endangered wildlife in controlled settings to increase the population size
E.g. the Pere David's deer was saved from extinction through captive breeding
-
-
A species that causes such dramatic changes to a landscape that it creates a new ecosystemE.g. beavers create dams, drastically changing the landscape
-
-
The series of changes in ecosystems that occurs over time following a disturbanceE.g. tree falls over, hare crushed, wolf can’t find food, can’t feed wolf family, family dies
-
-
The destruction of habitats, which usually results from human activities
E.g. we cut down a forest, leaving a bunch of woodland creatures homeless
-
-
The practice of clearing forests for logging or other human uses, and never replanting them
E.g. clear cutting a forest
-
-
A species that is accidentally or deliberately introduced to a new location, usually due to human activity
E.g. zebra mussels being carried over from Asia in ballast water
-
-
A species that can take over the habitat of native species or invade their bodies
- E.g. dandelions, take over lawns and fields wiping out other native plants
-
-
-
The use or extraction of a resource until it’s depleted
E.g. mining a mineral until it’s all gone
-
-
The death of all of the individuals of a species
E.g. golden frog, big horn ram, dinosaurs, etc.
-
-
The current accelerated of extinctions on earth
-
-
The renewal of degraded or destroyed ecosystems through active human interventionE.g. replanting trees in a destroyed forest
-
-
The regrowth of a forest either through the planting of seed or trees in an area where a forest was cut down
-
-
The use of a species to control the population growth or spread of an undesirable species
E.g. releasing Asian ladybugs to kill aphids
-
-
The use of living organisms to clean up contaminated areas naturally
E.g. releasing bacteria cleans up ecosystems
-
-
The use of organisms to ass essential nutrients to depleted soils
E.g. using clover to add nitrogen to soil
