P
In cases where pathway/vector is not specified/ cases of novel pathways/vectors. +
Unknown mechanisms of introduction were represented by a blank cell. +
One of the most important types of information in the practical approach to prevention and management of biological invasions is the identity of the pathways of introduction and details of vectors. These are necessary for the prevention of introduction of potentially invasive species and also for the containment of further spread of established invasions. Information on pathways and vectors of introduction of alien species has been recorded for the listed species where information was available. Descriptive terms describing pathways and vectors were standardized and listed as a look-up table. These terms have been adapted from Hayes (2005). +
A late veliger that is able to use its foot to crawl and provide temporary attachment +
Pertaining to the water column. Inhabiting the open sea, excluding the sea floor (rephrased from Lincoln ''et al.'', 1998). +
The secondary free-swimming larva in Sipunculida, that develops from a non-feeding trochophore (Ruppert & Barnes, 1994). +
Brush like (Prescott ,1969). +
Capable of producing both ova and spermatozoa either at the same time (Barnes ''et al.'', 1993). +
Engulfing prey/food item in cytoplasm +
composed of phosphoric acid or phosphates. +
An organism that obtains metabolic energy from light by a photochemical process such as photosynthesis (e.g. seaweeds, phytoplankton) (Lincoln ''et al.'', 1998). +
Coastal geomorphology and physical features. +
Seabirds/wader +
Specialist - modified radula used to inject toxins, e.g. cone shells +
Free-swimming, helmet-shaped, larva of nemerteans (ribbon worms) with an apical tuft, apical sensory organs, oral lobes and oral ciliated band (see Stachowitsch, 1992, Rupert & Barnes, 1996). +
Branching like a feather – an elongate main axis with lateral branches or lobes (Prescott, 1969). +
Branched tentacles, used as filtration mechanism +
Living in the fluid medium (water or air) but unable to maintain their position or distribution independently of the movement of the water/air mass (adapted from Lincoln <i>et al.</i>, 1998). +
Common in OSPAR Regions II, III, IV +
Feeding at least in part on materials captured from the plankton (Barnes ''et al.'', 1993). +
This refers to invasive plant species which are unintentionally introduced into a new area/region carried on or with the habitat material of some intentionally planted flora. +
This refers to plant species which are planted intentionally for some purpose resulting in the introduction of an invasive plant into a new area/region (e.g. for erosion control). +
A ciliated, free swimming larva; lacks a mouth but in older stages may include a gastrovascular cavity (Stachowitsch, 1992) +
Living permanently at the water surface due to their own buoyancy, normally positioned partly in the water and partly in the air. +
Transfer of male gametophyte (pollen) to the 'female' part of a flower +
18-<30 psu (included under MNCR Reduced, 18-30 psu) +
An ambush predator that uses a sudden, rapid movement to 'pounce on, grab or swallow' its prey once the prey in within short range. +
Predatory behaviour in which one animal species captures a member of another species (Lincoln ''et al.'', 1998). OR mobile animals that attack kill and consume individual prey items, usually one at a time. +
Species that are known to be present in their introduced range and are subject to some control option. +
Common in OSPAR Regions II, III +
A condition of hermaphroditism in plants and animals where male gametes mature and are shed before female gametes mature (Holmes, 1979). +
A condition of hermaphroditism in plants and animals where female gametes mature and are shed before male gametes mature (Holmes 1979). +
Larval pycnogonid that bears three pairs of appendages, the chelicerae, palps and ovigerous legs (Ruppert & Barnes, 1996). +
Third larval stage in Decapoda, characterized by antennal locomotion (see Stachowitsch, 1992) +
Males develop from diploid fertilized eggs but subsequently eliminate or silence the paternal genome +
An organism that hunts in a team, pack, pod, flock, swarm etc +
An organism that chases after, catches and subdues mobile prey (e.g. predatory polychaetes, squid, fish, otter, seal, seabirds) +
Q
Body size measured in terms of mega, macro, meio/meso and micro. +
Body size measured in numerical values. +
R
Symmetrical about any plane passed perpendicular to the oral/aboral axis (Barnes ''et al.'', 1993). +
Specialist - protrusile anterior region of digestive tract; refers to chitinized teeth along the radular membrane (Stachowitsch, 1992). +
A species which is present at low or relatively low densities; used to describe single occurrences of the species where appropriate. +
A species which is found in relatively low to moderate densities (accounts for non-discrete nature of abundance terms/parameters described here). +
A species which is fluctuates between relatively low to high densities (accounts for such phenomena as population explosions). +
