Distribution and Habitat
Country distribution from AmphibiaWeb's database: Albania, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, France, Germany, Greece, Hungary, Italy, Liechtenstein, Luxembourg, Macedonia, the Former Yugoslav Republic of, Montenegro, Netherlands, Poland, Romania, Serbia, Slovakia, Slovenia, Spain, Switzerland, Ukraine. Introduced: New Zealand, United Kingdom.
The species lives usually in mountains up to the alpine belt. It occurs, however, at much lower altitudes. The populations occur usually in the forest and in the areas formerly occupied by forests. This is true especially for lowland populations. In the aquatic phase, it inhabits lakes, ponds, rivulets and swamps with clear stagnant or semi-flowing water. Observations in the Ukrainian Carpathians revealed that the Alpine Newt prefers clearer and cooler waters than the syntopic Carpathian Newt (Lissotriton montandoni). In Montenegro, the Alpine Newt is syntopic with the Smooth Newt (Lissotriton vulgaris) in the Upper Zone of the Montenegrin karst, and is restricted to elevations above 870 m (Ćirović et al. 2008). The Alpine Newt has also been found in other areas of exposed karst within the Balkans but at much lower elevations (e.g. on Mt. Velebit, Croatia, at 80 m) than reported for Montenegro populations (Kalezić et al. 1990).
Life History, Abundance, Activity, and Special Behaviors
The daily activity is similar to that of Triturus and Lissotriton. Hibernation begins in September - October and ends in February (or earlier in the south) to May. The variation in timing and duration of active period depends on latitude and altitude. In highlands the activity period is shorter.
The same applies for its reproductive period. In general, the courtship pattern of the Alpine Newt is more similar to that in Lissotriton vulgaris and Lissotriton montandoni than in the crested newts (Triturus cristatus superspecies). Adults and larvae tend to be bottom dwellers. The clutch contains probably 73-190 eggs deposited singly or in short chains of 3-5 eggs over a few days. In the Ukrainian Carpathians, metamorphosis occurs in September, later than in other newt species. However, larval hibernation and even neoteny (i.e. reproduction in the larval condition) occurs frequently in this species. Some populations in the mountains consist mostly of neotenic individuals. The sexual maturity in normal individuals is reported for the age of two or three years.
Just after transition to active feeding, larvae of the Alpine Newt eat prey of the same taxa as larvae of the Carpathian Newt. During subsequent development, they consume increasing amounts of Mollusca, large forms of microcrustaceans (Daphniidae), and aquatic insects. In general, larval I. alpestris feed on more benthic prey than other syntopic larval newts. Feeding of adults is similar to that in other newts, such as those in the genus Triturus, and Lissotriton. Consumption of terrestrial prey by aquatic adults, as well as oophagy on nesting sites, is common.
Dorsal crests in male newts (family Salamandridae) are particularly conspicuous during breeding season and their origin may be related to the complex courtship behaviors of these salamanders. In a new analysis that looks at many species and combines information on evolutionary relationships with data on morphology as well as behaviors, Wiens et al. (2011) reveal a complex relationship among these traits. The various dorsal crest traits (in mature males) that characterize different species have been lost repeatedly. The evolution of the dorsal crest may be related to certain specific behaviors such as fanning and whipping of the tail. Species with higher numbers of crest-related traits also have larger repertoires of courtship behaviors.
Trends and Threats
Newt habitat in the Montenegrin holokarst region (a rocky, dry habitat) has been steadily declining over the past several decades, as many ponds originally created for cattle drinking and human water consumption have been abandoned by humans (Ćirović et al. 2008).
Relation to Humans
The phylogeography of I. alpestris has recently been investigated using mtDNA, revealing five major clades (Sotiropoulos et al. 2007). Clade A consists of populations from southeastern Serbia, with this clade originating in the late Miocene. This Serbian lineage is thought to be ancestral to a western and an eastern lineage, with a mid-Pliocene divergence. The western lineage is divided into Clade B (Italy) and C (central Europe and Iberia). The eastern lineage is divided into Clade D (southern Balkans) and E (central-northern Balkans). Eastern clades seem to have been isolated in multiple refugia during glaciation cycles, based on high sequence divergence. Western clades are thought to have colonized central, western, and northeastern Europe from a possible refugium in central Europe (Sotiropoulos et al. 2007).
This analysis also indicates that paedomorphic lineages of I. alpestris appear to have evolved during early to mid-Pleistocene, likely in response to the ongoing climatic fluctuations (Sotiropoulos et al. 2007).
At the southernmost edge of the species range, in Greece, two major mitochondrial lineages of I. alpestris veluchiensis have been separated since the mid-Pleistocene. Populations from Peloponnisos and the Greek mainland show significant differences in both nuclear gene frequencies and mitochondrial haplotypes, and consistently fall out into separate, strongly supported clades. These lineages have been proposed to warrant separate conservation status (Sotiropoulos et al. 2007).
