kerry slug habitat

The habitat choice of A. subfuscus and P. carolinianus reflected local availability of substrate. The Habitats Directive protects the Kerry slug outside the SACs by Article 12 (1), which obliges European Union member states to: Conservation status reports from Portugal and Spain were not yet available in August 2009. Kerry Slug. Habitat. This turns into the free oviduct after the vas deferens carrying the sperm branches off. Kerry Slugs are protected in all of the locations that they are found in. [24] Similar distribution patterns have been observed in other species of animals and plants. A three-year research project has been completed on the Kerry Slug, the first of its kind on the species. Threat status Europe: Lower Risk: Least Concern ... and it has a sufficient large habitat. Kerry Slugs are protected in all of the locations that they are found in. (2006). The slugs have two colour morphs, brown and black. The Kerry slug's scientific name is Geomalacus maculosus, where maculosus means "spotted" from the Latin word macula, a spot. [18], The species has in unusual defensive behaviour; whereas most land slugs retract the head and contract the body but stay firmly attached to the substrate when they are attacked or threatened, the Kerry slug retracts its head, lets go of the substrate and rolls itself into a ball-like shape. A Kerry slug habitat assessment survey was undertaken in April 2018to determine the extent of suitable habitat for the Kerry slug within the final route alignmentand compulsory purchase order (CPO) boundary Refer to Appendix 11.1, Volume 3 of this EIAR for survey details and results. [10], The body of the Kerry slug is glossy and is covered on both sides with about 25 longitudinal rows of polygonal granulations. The Kerry slug (Geomalacus maculosus) is notable for its distribution, being found only in Kerry and West Cork in Ireland as well as in northern Spain and Portugal. The Kerry spotted slug Geomalacus maculosus has a restricted European range and may be threatened by loss of habitat. [25][26] In support of such an origin or of a more recent human-mediated introduction, the genetic diversity of the Kerry slug in Ireland was found to be greatly reduced compared with that of the Iberian populations. 1). Black slugs predominate in heathlands, whereas the brown form is only found in woodlands. Under this definition, no monitoring of the Kerry Slug had been undertaken in Ireland as of May 2010. Kerry slug metric trap surveys were undertaken under NPWS licence(C132/2014) in 2014 Ke.rry slug surveys and habitat assessments were carried out under licence (C008/2016) in 2016. In fact, a better suiting description would be a generalist that feeds a plethora of organic matters including leaves of living plants, lichens and mushrooms some slugs are even found to feed on small fruits such as strawberries. [18] Platts & Speight [18] considered the depiction by Godwin-Austen (1882)[14] to be the most accurate of those by earlier authors; others depicted the atrium too short. The Kerry slug is a gastropod, a class of molluscs that includes all snails and slugs, including terrestrial, freshwater and marine species. Forested sites were a com-bination of conifer plantations and oak woodlands (Fig. [18] The elongated portion of the atrium further from the genital pore than the insertion of the oviduct is termed the atrial diverticulum. [24][38] Although there was a geographical association with sandstone areas, the new locality in Galway is on granite. From 1991 to 1999 between 44 and 328 eggs hatched each year allowing a number of animals to be distributed to British zoos. The Irish yellow slug (Limacus maculatus) is quite different from the Kerry slug (Geomalacus malaculosus), albeit for its rather similar name.The first is a keel back slug from the Limacidae family, recognizable by the keel at the end of its foot. 1 day ago. [10] These slugs are difficult to measure accurately because of their unusual startle response. The slug is attractively marked with white or yellow spots. Birds, mammals, fish, and even the Kerry Slug all call this part of the world their home. [25], The need to improve monitoring was discussed by the NPWS Threat Response Plan of 2010, which recognised that population statistics were still deficient, particularly outside the SACs. If slugs are your thing, then the Kerry Slug should be looked out for in wet weather. "British slugs (Pulmonata; Testacellidae, Arionidae, Limacidae". The most serious threat to the Kerry slug is probably the modification of habitat, which reduces its lichen and moss food sources. Given that the slug has thus far been recorded exclusively at locations in Ireland and north-western Iberia, it can be said to tentatively possess a Lusitanian distribution. [10] Eggs are laid in clusters of 18 to 30,[10] and are held together by a film of mucus. [7] The skin mucus is usually pale yellow and varies in viscosity. These ribs are absent or scarcely discernible on the side areas. [7] The bodies of preserved juvenile specimens are up to 3 cm (1.2 in) long with a mantle length of 10 mm (0.39 in). Although the distribution of this slug species includes south-western Ireland—including County Kerry—the species is more widespread in north-western Spain and central-to-northern Portugal. [24] This can lead to the local disappearance of the species, which was documented in Spain. The site is of international importance and has been dated at older than 385 million years; probably second oldest in the world. This characteristic is responsible for the common name of the species, the lettuce sea slug.
