Fire salamander
The fire salamander (Salamandra salamandra) is a common species of salamander found in Europe.
It is black with yellow spots or stripes to a varying degree; some specimens can be nearly completely black while on others the yellow is dominant. Shades of red and orange may sometimes appear, either replacing or mixing with the yellow according to subspecies. This bright coloration is highly conspicuous and acts to deter predators by honest signalling of its toxicity (aposematism). Fire salamanders can have a very long lifespan; one specimen lived for more than 50 years in Museum Koenig, a German natural history museum.
Despite its wide distribution and abundance, it is classified as Vulnerable on the IUCN Red List due to its susceptibility to infection by the introduced fungus Batrachochytrium salamandrivorans, which has caused severe declines in fire salamanders in parts of its range.
Several subspecies of the fire salamander are recognized. Most notable are the subspecies fastuosa and bernadezi, which are the only viviparous subspecies – the others are ovoviviparous.
Some former subspecies have been lately recognized as species for genetic reasons.
Fire salamanders are found in most of southern and central Europe. They are most commonly found at altitudes between 250 metres (820 ft) and 1,000 metres (3,300 ft), only rarely below (in Northern Germany sporadically down to 25 metres (82 ft)). However, in the Balkans or Spain they are commonly found in higher altitudes as well.
The scientific article titled "Water, Stream Morphology and Landscape: Complex Habitat Determinants for the Fire Salamander Salamandra salamandra" explored the factors influencing the distribution of the fire salamander, a semiaquatic amphibian species, in northern Italy. The study aimed to understand the relationship between environmental features and species distribution, essential for effective habitat conservation.
Researchers evaluated three main factors: stream morphology, biotic features of water, and the composition of the surrounding landscape near wetlands. They collected data from 132 localities over four years and used an information-theoretic approach to build species distribution models. Variance partitioning was then employed to assess the relative importance of environmental variables.
