“…Viviparous populations occur only in the Cantabrian mountains and Cantabrian coast (central-northern Iberia; S. s. bernardezi), the southwest Pyrenees (S. s. fastuosa) and on two small offshore islands (San Martiño and Ons) in the Atlantic ocean, 3.6 and 6 km from the northwestern coast of Spain, respectively (S. s. gallaica; Velo-Antó n et al, 2007; Figure 1). Transitions from ovoviviparity to viviparity have occurred repeatedly in the three amphibian orders (Wake, 2004), and viviparity is a derived reproductive mode in salamanders (Veith et al, 1998;García-París et al, 2003;Weisrock et al, 2006). An early phylogenetic and phylogeographic study using mitochondrial and nuclear DNA markers indicated that viviparity arose once within S. salamandra in the Cantabrian Mountains (northern Iberian Peninsula; S. s. bernardezi), and spread along the coast to the Pyrenees with the evolution of S. s. fastuosa (García-París et al, 2003).…”

Genetic drift and rapid evolution of viviparity in insular fire salamanders (Salamandra salamandra)

Continental islands offer an excellent opportunity to investigate adaptive processes and to time microevolutionary changes that precede macroevolutionary events. We performed a population genetic study of the fire salamander (Salamandra salamandra), a species that displays unique intraspecific diversity of reproductive strategies, to address the microevolutionary processes leading to phenotypic and genetic differentiation of island, coastal and interior populations. We used eight microsatellite markers to estimate genetic diversity, population structure and demographic parameters in viviparous insular populations and ovoviviparous coastal and interior populations. Our results show considerable genetic differentiation (F ST range: 0.06-0.27), and no clear signs of gene flow among populations, except between the large and admixed interior populations. We find no support for island colonization by rafting or intentional/accidental anthropogenic introductions, indicating that rising sea levels were responsible for isolation of the island populations approximately 9000 years ago. Our study provides evidence of rapid genetic differentiation between island and coastal populations, and rapid evolution of viviparity driven by climatic selective pressures on island populations, geographic isolation with genetic drift, or a combination of these factors. Studies of these viviparous island populations in early stages of divergence help us better understand the microevolutionary processes involved in rapid phenotypic shifts.

“…A relatively large number of interesting studies have been carried out on the genetic variation of urodelan taxa including the genus Triturus regarding various aspects, e.g., systematic, phylogenetic and geographic divergence [25][26][27][28][29]. In order to examine genetic variation among populations, various biochemical and molecular biology methods were used such as serum albumin [17], enzyme isozymes [30], randomly amplified polymorphic DNA chain reaction (RAPD PCR) [31,32], mitochondrial DNA [26,[33][34][35], Amplified Fragment Length Polymorphism (AFLP) [19][20][21][22] and sequencing of transcriptome-based genetic markers [36].…”

In the present mini-review, the results and unpublished data that were collected on Triturus vittatus vittatus in Israel on the southern border of its distribution, and on its adaptation to the Mediterranean semi-arid climate and to arid climate environments on the southern border of its distribution were presented. The contribution of the present paper is in building a model based on the results collected on the distribution, life cycle, behaviour and genetic variations among different populations in northern Israel down to the central coastal plains and near the desert of this species. More specifically, this model is based on the morphology, biology, behaviour and life cycle of T. v. vittatus adaptation. By considering these many parameters, one hypothesis was raised and is supported. The adaptation to and selection of habitats depends mainly on the terrestrial phase and less on the aquatic phases. There are various breeding places in all of the habitats, however, the newts are mainly used to winter ponds, many of which dry up in summer where the larvae can grow and complete metamorphosis. The adaptation of the breeding ponds is not under ecological conditions during larvae growth and complete metamorphosis, but the time of adult breeding and larvae growth occur year-round. The molecular genetic variation in the different areas support our hypothesis that climate is affected by altitude and proximity to the desert. During the life cycle the newts have two habitats aquatic and terrestrial and the adaption to terrestrial habitats is more affected on the newts distribution than the aquatic habitat. The quality model of fitness T. v. vittatus to extreme conditions was suggested.

The purpose of the present study was to examine the genetic variation in Salamandra infraimmaculata from different breeding site habitats using the Amplified Fragment Length Polymorphism (AFLP) method. The results of the dendogram from a hierarchical cluster analysis show that the grouping of S. infraimmaculata as cluster 5 differs from all the other clusters, including the St1 (Tel-Dan stream) population, which was the most predictable. Five Haplogroups (Hg) were characterized. The mean number of alleles per locus in each population (Ne) ranged from 10.566 (Sp1) to 2.720 (Po6). An average estimated heterozygosity (He) by population ranged from 0.100 (Po6) to 0.186 (St1). Population St1, a permanent breeding site where water was available all year round, exhibited the highest level of polymorphism, while population Po6, from the ephemeral breeding site, exhibited the lowest level of polymorphism. Gene flow between clusters showed that clusters 3 and 4 are sources of migrants and also receive gene flow, while clusters 1 and 2 may be a source of migrants but may not receive much gene flow. A phylogenetic analysis, based on clustering using Nei's genetic distance, demonstrated that the Tel-Dan population is located on a separate branch within its sub-population. The conclusion of the present study shows that the genetic divergence among isolated populations is not correlated to distance but is affected by the variation of habitats.
