Recovery Strategy for the Leatherback Turtle in Atlantic Canada

Appendix A - Glossary

A small flat-bodied crustacean of the order Amphipoda.

The accumulation of a substance, such as a toxic chemical, in the tissues of a living organism.

The increasing concentration of a substance, such as a toxic chemical, found in the tissues of a living organism as you move up the food web. Simple organisms such as algae can absorb and bioaccumulate minute quantities of a substance which are transferred through the food chain to higher living species such as fish, bird, etc. Biomagnification along a food chain will result in the highest concentrations of a substance being found at the top of the food chain.

The harvest of fish or shellfish other than the species for which the fishing gear was set.

A bony or chitinous case or shell covering the back or part of the back of an animal.

Having benefit for one member of a two-species association but neither positive nor negative effect on the other.

Critical Habitat:
the habitat that is necessary for the survival or recovery of a listed wildlife species and that is identified as the species' critical habitat in the recovery strategy or in an action plan for the species.

The removal of a species from the list of species at risk following its recovery.

Endangered Species:
a wildlife species that is facing imminent extirpation or extinction.

Food Chain:
a community of organisms where each member is eaten in turn by another member.

the act of searching for food and provisions.

Gene flow:
Transfer of genes from one population to another of the same species.

A short line attached to a trawl.

a protective structure of stone or concrete; extends from shore into the water to prevent a beach from washing away.

a great, circular motion of water in each of the major ocean basins centered on subtropical high-pressure region, with circulation clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.

Newly hatched fish or reptile.

The lower jaw of vertebrates.

The tentacled, bell-shaped, and sexually mature stage in the life cycle of a jellyfish and other members of the Coelentera.

Death rate.

Localized death of cells or tissues through injury or disease.

Pertaining to animals that live at the surface of the ocean, away from the coast.

PIT tag:
Passive Integrated Transponder tags are microchips that are injected into an animal's muscle tissues using a hand-held applicator gun.

The front, or ventral part, of the shell of a turtle.

A breeding colony of birds or animals.

A sloping surface of stone, concrete or other material used to protect an embankment, natural coast or shoreline against erosion.

A rubble sustaining wall, often used along shorelines to prevent erosion.

A wall of stone, concrete, or other sturdy material, built along the shoreline to prevent erosion even by the strongest and highest of waves.

Seismic Exploration:
The use of seismic energy to probe beneath the surface of the earth.

The wide range of voluntary actions that people are taking to care for the environment.

The automatic measurement and transmission of data from remote sources, by radio or other means, for recording and analysis.

A process through which cold and usually nutrient-rich waters rise from the bottom of the ocean to its surface.
