Pathway / Vector

Pathway

A pathway is the route a NIS takes to enter or spread through a non-native ecosystem e.g. vessels. Each pathway may have a number of vectors.

Vector

A vector is a transfer mechanism and is the physical means by which species are transported from one geographic region to another. More than one vector within a pathway may be involved in a transfer of species.

Pathway / Vector – Levels of certainty:
LevelCriteriaExamples
Direct evidenceThe species was actually found associated with the specific vector(s) of a pathway at the time of introduction to a particular locality within a country/country region.Documented evidence of an introduction: release to the wild for stocking or biological control; escape/release of live food; import of cultured species and documented findings of their associate organisms, parasites and diseases on transmission; appearance of organisms by hull fouling, ballast water discharge sampling or other ship vectors documented upon an arrival with appropriate scientific methods.
Very likelyThe species appears for the first time in a locality where a single pathway/vector(s) is known to operate and where there is no other explanation that can be argued for its presence except by this likely pathway/vector(s).A highly localized distribution of a species in an area adjacent to an isolated port or other locality where the only pathway is vessels and its vector(s) (ballast water, hull fouling, etc). This often involves geographically discontinuous distributions. It may be a continuous spread as in case of introduction by canals or by natural means. The conclusion is deduced from the analysis of the invasion event and species distribution patterns.
PossibleThe species cannot be convincingly ascribed to a single pathway, but is known to be introduced by this pathway(s) elsewhere.There may be more than one pathway involved in the introduction within a country/country region. Arrival of a species known to have taken place elsewhere by the same pathway(s) which operates in an area. A conclusion is made by expert judgment based on pathways currently or historically present.
UnknownInvasion of a given alien species cannot be clearly explained.Where no rational explanation for the appearance of a species in a given country/region.

Population status

Population status (the lowest level of certainty):

Unknown. There is no reliable information on population status of a species.
Established. A species is known to form a reproducing population in a wild.
Not established. There is no evidence of a species’ reproducing population in a wild.

Population status (the moderate level of certainty):
Extinct/no recent record. There are old records where a species was recorded but have not been seen in the same region since.
Rare/single record. There are only casual observations or a single record of a species'presence available.
Common. A species with successfully reproducing populations in an open ecosystem, which are unlikely to be eliminated by man or natural causes. Not dominating native communities.
Abundant. A species with successfully reproducing populations in an open ecosystem, which are unlikely to be eliminated by man or natural causes. Locally dominating native communities.
Very abundant. A species with successfully reproducing populations in an open ecosystem, which are unlikely to be eliminated by man or natural causes. Largely dominating native communities.
Outbreak. A species undergoing pulse-like, short-term (days to few months) exponential population growth during which they have an adverse effect on one or more of the following: biological diversity, ecosystem functioning, socio-economic values and human health.

Recipient region

The country/region for which introduction is recorded.

1. Limnetic [<0.5psu]
2. β-Oligohaline [0.5-3psu]
3. α-Oligohaline [3-5psu]

Source region

The area the species was introduced from to the recipient country/country region. Depending on the information availability may be ascribed to a particular locality (e.g. port), a country, a LME or a larger Ocean region.
CAUTION: in many cases the source area will be not the same as the area of native origin which is defined in the SPECIES block of the database.

Species status

Non-indigenous species. Non-indigenous species (synonyms: alien, exotic, non-native, allochthonous, introduced) are species, subspecies or lower taxa (such as a variety, form) introduced outside of their natural range (past or present) and outside of their natural dispersal potential. This includes any propagule of a NIS, such as a gamete, seed or resting spore, a gravid female or a pair of individuals of different sexes (in sexual reproduction), or a vegetative reproductive organ and section of tissue (in asexual reproduction), which might survive, reproduce and subsequently form a population. It also includes hybrids between an alien species and an indigenous species, fertile polyploid organisms and artificially hybridized species irrespective of their natural range or dispersal potential.

Cryptogenic. Cryptogenic species are such species which cannot be reliably demonstrated as being either introduced or native. In some cases the true origin of a species remains obscure because of either insufficient taxonomic knowledge or due to a lack of records from the time they became introduced, or for other reasons.

Temperature range

Indicate min. and max. annual temperature range in the area where a species is known to maintain an established (reproducing) population.

Wave exposure

Exposed. Open coastline facing prevailing wind and receiving both wind-driven waves and swell.

Semi exposed. Generally open coasts facing away from prevailing winds or sheltered by offshore reefs/structures.

Sheltered. Coasts with a restricted fetch (<20 km) and lacking persistent swell.

Zonation

Ecological zone(s) occupied by a species throughout its life cycle.

Benthic - Bathyal. Synonym: continental slope. The seafloor between the edge of the continental shelf and abyssal plain (200-4000 m).

Benthic - Littoral. Synonym: intertidal. The shore between the high and low water marks.

Benthic - Sublittoral beyond photic zone. Synonym: lower circalittoral. The lower part of the continental shelf, where photosynthesis cannot take place.

Benthic - Sublittoral within photic zone. Synonyms: subtidal, infralittoral. The shallow part of sublittoral where photosynthesis can occur.

Benthic - Supralittoral. Synonyms: splash zone, spray zone, supratidal zone. The area above the spring high tide line, subject spray or splash.

Pelagic - Littoral. Water mass within littoral zone.

Pelagic - Neritic. Water mass above the continental shelf.

Pelagic - Offshore. Synonym: oceanic. Water mass beyond the continental shelf.

Comments:
As it occurs in lagoons it almost certainly can tolerate salinities that exceed 35 psu. Development is best within the range 10 to 30 psu and is inhibited at levels below 6 psu. Reproduction does not take place below 3 psu. At low salinities growth of tubes is slow due to the reduced calcium content in the water.

Comments:
Its distribution in Britain is thought to be close to its northern range on account of its temperature requirements for spawning. However, spawning can take place once temperatures exceed 15C. Tubes can grow at 10mm a week under ideal conditions. Dixon (1981) indicates that a minimum of 18C is needed for spawning.

Comments:
It was first found in Weymouth and soon after in 1939 appeared in Plymouth, where it is still present (pers. ob. 2005). Later in Somerset at Portlock Wier in 1968, then Dover where it still is present (pers. ob. 2012) It is present in Southampton Docks. In 1981 it was found in a mill pond at Emsworth, in the western part of Sussex. Locally abundant and can form massive reef-like growths sufficient to overgrow firm surfaces to form large encrustations. Populations can undergo a wide variability in population abundance between years. The species is well recognised and may be expected to become recorded in many more areas. Populations may on occasion collapse when within contained water bodies as will have happened at the Emsworth Millpond in west Sussex.

Comments:
Its true origin is unknown but some have considered it to have originated from the Indo-Pacific, possibly Australia. This may not be correct as specimens in Indonesia and India are recognised as F. ushakovi. May be from eastern South America but considered to be an introduction there by some. Its arrival in northern Europe is considered to be an introduction.
