Large alpine salamander description

KingdomAnimalia
PhylumChordata
ClassAmphibia
OrderCaudata
FamilySalamandridae
GenusSalamandra (1)

The large alpine salamander was first described as recently as 1988 (3). It is a little-known species, that is generally similar in appearance to the alpine salamander (Salamandra atra). It differs in its larger size (2), the fact that it has a rounded tail tip, whereas the alpine salamander has a pointed tail, and the absence of glandular pores on the back (2). It is black in colour, has a flattened head and web-like skin between the digits (3).

Also known as
Lanza’s alpine salamander.

Large alpine salamander biology

Little is known of the ecology of this unusual alpine amphibian. It is active during summer, from May to October when it is typically nocturnal or crepuscular. In times of heavy rain it may become active during the day (2). It is a territorial species (4) and feeds on a broad range of land invertebrates, sometimes also living in the water (6). In periods of bad weather, individuals take refuge under rocks or in crevices (2).

Very little is known of the reproductive behaviour of this salamander. They are thought to mate towards the end of summer. Between one and six young are produced, after a gestation period of up to three years (5). There is no ‘tadpole’ stage; instead, the young salamanders are immediately adapted to terrestrial life (2). Sexual maturity is reached at around eight years of age (4) and individuals can live for over 20 years (7).

Large alpine salamander range

This species occurs in a restricted range consisting of just a few sites in the southwestern Alps of south-east France and north-west Italy (Cottian Alps) (2).

Large alpine salamander habitat

Found in alpine meadows, typically close to brooks (2). Its elevation distribution goes from about 1200 up to 2600 m (5).

Large alpine salamander status

This species is classified as Vulnerable (VU C2a) by the IUCN Red List 2003 (1).

IUCN Red List species status – Vulnerable

Top

Large alpine salamander threats

The main threats facing this vulnerable species are thought to include habitat loss, drainage of habitats, disturbance by vehicles, over-collecting and genetic problems resulting from the very small sizes of populations (2). The small geographic distribution of this species means that it is very vulnerable to chance events, such as extreme weather. In some cases, erosion by alpine streams can be a problem for the survivorship of some populations (8).

Large alpine salamander conservation

Surprisingly, this unique and vulnerable European alpine salamander is not included in important European conservation legislation or Red Lists, including the Habitats Directive. Regular monitoring and further research into this species are essential in order to inform future conservation actions (2) (8).
