Life History, Abundance, Activity, and Special Behaviors
Females are active in daytime during the breeding period; afterwards adults are active at twilight, spending the day under logs, snags, stones, rodent burrows and holes. During rainy weather salamanders regularly leave their hiding places by day. The appearance of active salamanders on the land surface in day time indicates the approach of rain. Hibernation, typically in groups, occurs in the northern part of the range, whereas in the south (e.g., in Israel) activity ceases during hot summer period. Similarly, in central Europe reproduction occurs between spring and autumn, whereas at the south of the range it is confined to winter. Mating takes place on land, and male-male combats for a female often takes place. The species is typically viviparous, and the female releases the young into water, usually shallow brooks. The number of larvae per female, as well as their stage at birth time, varies among subspecies. Salamandra salamandra bernardezi and, sometimes, S. s. fastuosa give birth to completely metamorphosed young salamanders. Larval development takes several months, but in many cases they overwinter and finish their metamorphosis in the next year. Most larvae occur in fishless parts of brooks, which is caused by fish predation. As a rule, larvae start active feeding just after birth. Age changes in diet during ontogeny are minor and related mainly to the use of larger prey. Larvae consume primarily upon rheophilous invertebrates: Gammaridae, larval Ephemeroptera, Diptera, etc. In semi-flowing waters, typical limnophilous preys (e.g., Diaptomidae) are included in their diet. Adults do not consume the small preys that are eaten by juveniles: Acarina, Geophylomorpha, and Collembola. However, they eat large Mollusca, Myriapoda (Oniscomorpha, Polydesmida and Juliformia), Coleoptera, etc.

This is the first species from which Batrachochytrium salamandrivorans (Bsal) infections have been identified (Martel et al. 2013).

Although Fire Salamanders are assumed to be an aposematic species, where bright colors are viewed by potential predators as warning of toxicity, the costs associated with the honesty of their signaling and predator learning behavior has not been quantified. Preißler et al. (2019) tested whether the alkaloid content matched yellow coloration in a highly variable Fire Salamander population in Solling, Germany, (Salamandra salamandra terrestris) to determine if the species had an honest signal of toxicity. They found that the amount of yellow patterning did not correlate with the amount of toxins in individuals, as would be expected for a true aposematic species. The authors also found that the population was sexually dichromatic, with males being more yellow than females. Although these findings could be explained by sexual selection, statistical analysis of color variation indicated that site specific female choice was not a factor. These findings indicate that other, yet to be verified, biological processes are playing a role in the yellow coloration of Fire Salamanders, and that the toxins are produced by conserved bioactivity (Written by Ann T. Chang).

The pathogenic amphibian fungus known as Bsal (Batrachochytrium salamandrivorans) may be the most potent amphibian disease and poses extreme risk to natural populations, especially in salamanders. First detected in Fire Salamanders (Salamandra salamandra) in extreme southeastern Netherlands and adjacent Belgium and reported in 2013, it has spread to western Germany (with new reports from Bavaria), where it is having devastating effects. An entire issue of the journal Salamandra (2020, vol 56, issue 3, open access and available as PDF) is devoted to Bsal research centered in Germany. Salamander populations have essentially disappeared from the northern Eiffel region and are threatened in the southern Eiffel and Ruhr regions. Bsal has been present in Germany for at least 16 years and has been found in laboratory populations of the Common Frog, Rana temporaria, and field populations of the Great Crested Newt, Triturus cristatus. It is known to infect salamandrid species from southeast Asia, which appear to have been the source of the European outbreaks via pet trade importation. The goal in highlighting this important set of papers as stated by the editors "must go beyond documenting declines towards understanding spatio-temporal disease dynamics and the factors influencing the spread and impact of Bsal in different situations." In light of the seriousness of the Bsal threat in Germany, the authors' common goal is a national Bsal Action Plan, which would be of great importance for the international community of amphibian biologists and for the public (Written by David B. Wake).
