Association with vessel vectors

Actual evidence of being found in samples in a particular vector from any world region.

Anchor and anchor chains. Organisms found on anchors, anchor chain or within attached sediments, including anchor chain lockers.

Ballast water. Ballast water means water with its suspended matter taken on board a ship to control trim, list, draught, stability or stresses of the ship.

Biofouling. Biofouling means the accumulation of aquatic organisms such as micro-organisms, plants, and animals on surfaces and structures immersed in or exposed to the aquatic environment. Biofouling can include microfouling and macrofouling.

  • Macrofouling means large, distinct multicellular organisms visible to the human eye such as barnacles, tubeworms, or fronds of algae.
  • Microfouling means microscopic organisms including bacteria and diatoms and the slimy substances that they produce.
Biofouling comprised of only microfouling is commonly referred to as a slime layer.

Autogenic ecosystem engineers. Organisms which change the environment via their own physical structures (i.e. their living and dead tissues) such as corals, oysters, kelps, sea grasses, etc.

Allogenic ecosystem engineers. Organisms which modify the environment by causing physical state changes in biotic and abiotic materials that, directly or indirectly, modulate the availability of resources to other species (e.g. excavating deep burrows which other organisms co-occupy, damming the water flow, etc).

Keystone species. A keystone species is crucial in maintaining the organization and diversity of its ecological community, by determining the types and numbers of other species.

Life form

Neuston. Organisms that live on (epineuston) or under (hyponeuston) the surface film of water bodies.

Zoobenthos. Animals living on or in the seabed.

Semelparous. Organisms breeding once in their lifetime.

Reproductive type

Asexual. Budding, Fission, Fragmentaion, including parthenogenesis. A form of asexual multiplication in which:
a) a new individual begins life as an outgrowth from the body of the parent. It may then separate to lead an independent existence or remain connected or otherwise associated to form a colonial organism;
b) the ovum develops into a new individual without fertilization;
c) division of the body into two or more parts each or all of which can grow into new individuals is involved.

Self-fertilization. Selfing or autogamy. The union of a male and female gamete produced by the same individual.

Sexual. Permanent hermaphrodite, Protandrous hermaphrodite, Protogynous hermaphrodite, Gonochoristic.
Capable of producing both ova and spermatozoa either at the same time. A condition of hermaphroditism in plants and animals where male gametes mature and are shed before female gametes mature or vice versa.
Having separate sexes.

Salinity

3. α-Oligohaline [3-5psu]
4. β-Mesohaline [5-10psu]
5. α-Mesohaline [10-18psu]
6. Polymixohaline [18-30psu]
7. Euhaline [30-40psu]
8. Hypersaline [>40psu]

Sociability

Colonial. Descriptive of organisms produced asexually which remain associated with each other; in many animals, retaining tissue contact with other polyps or zooids as a result of incomplete budding.

Gregarious. Organisms living in groups or communities, growing in clusters.

Solitary. Living alone, not gregarious.

Sub-species level

A geographical subset of a species showing discrete differences in morphology, coloration or other features when compared with other members of the species. Subspecies may also differ in their habitat or behavior, but they can interbreed. Often the lowest taxonomic level within a classification system.

Synonym

Valid synonyms of a species (not all of them).

Toxicity

Poisonous. An organism capable of producing poison that gains entry to another organism body via the gastrointestinal tract, the respiratory tract, or via absorption through intact body layers.

Comments:
Like many other aquatic species, Salvelinus namaycush fertilizes eggs externally, but unlike other species do not construct a 'redd' or nest. The act of spawning occurs predominately at night; where males will approach a female, press against her sides and quiver. During this act the females' eggs fall into rocky outcroppings beneath her after being fertilized by the male. This act of courting is repeated until all the eggs of the female are released. Occasionally, up to seven males and three females may interact together in a single spawning act.

Comments:
Hg concentrations from lakes in five Alaskan parks were among the highest of the 23 western parks measured and exceeded both ecological and human health impairment benchmarks.
Although once an important commercial fish stock, lake trout levels in the Great Lakes dropped sharply during the 1950's. Lake trout are still highly valued as a sport fish and anglers who seek this species contribute to the regional economy of areas with fishable populations through the purchase of fishing licenses.
