FIGURE 1 in Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain
FIGURE 1. Linear morphometric analysis of MNHN 0.4675, the lectotype of Salamandra auriculata Holbrook, 1838. Shown are the 75 scores and overall densities on the first linear-discriminant axis (a), the assignment probabilities for each specimen (b), a boxplot of the highest-loading trait with significant median difference (AG~SVL; c), and a map of the samples (d) with type localities indicated by triangles. We estimate strong support for allocation of the specimen and name to the Desmognathus auriculatus A lineage of northern Florida, southern Georgia, and southern Alabama. This necessitates a new name (D. valtos) for the D. auriculatus B/C lineage from the Atlantic Coastal Plain of the Carolinas.

Figure 1. (a) Distribution of both species displaying reproductive polymorphism, Salamandra salamandra (in blue) and Salamandra algira (in green). In red, the area of occurrence of pueriparity within each species. Values next to each pueriparous nuclei denote the frequency of multiple paternity. (b) Detail of the western-most distribution area of S. algira where the pueriparous lineage occurs (in red). The box shows the number of fathers and the proportion of the offspring sired by each male for all four studied females. Numbers in brackets are clutch size in each female.

Data from: 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 (FST 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 9,000 years ago. Our study provides evidence of rapid genetic differentiation among 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.

Data from: Weighing density and kinship: aggressive behavior and time allocation in fire salamander (Salamandra infraimmaculata)
Kin-biased behavior (that is responding differentially to kin and non-kin) is thought to be adaptive in many social interactions. One example of this kin bias is behaving less aggressively toward a relative than a non-relative, a behavior which yields inclusive fitness benefits. However, data are lacking about the ability of animals to weigh their preference for kinship and the density of conspecifics simultaneously and to respond accordingly. Fire salamanders (Salamandra infraimmaculata) larviposit in high densities in ponds. Thus, larvae of different females confront competition and predation by other larvae. We studied whether larvae prefer their kin over particular density or vice versa. We experimentally used a transparent glass aquarium with inner chambers to test the responses of a focal larva toward its siblings and non-siblings. Specifically, we quantified the time a focal larva spent near its siblings or non-siblings, presented in varying densities, and the aggression level it demonstrated. We found that focal larvae spent more time near non-siblings if non-sibling and sibling groups were of equal density. The focal larvae were also more aggressive toward non-siblings. The results may be explained by the cannibalistic nature of these larvae: high density may provide more opportunities for food, especially when non-siblings are present. Further explanations for these findings may include other advantages of staying in a larger group and/or the stronger olfactory and visual stimulation offered by groups compared to a single individual. These findings suggest that larvae make differential responses toward conspecifics depending simultaneously on the level of relatedness and the density of the group. Such responses have important implications for social - aggregation decisions and may especially affect the fitness of cannibalistic species.

FIGURE 2 in Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain
FIGURE 2. Holotype (MNHN 2021.0131/RAP0955) of Desmognathus valtos. Specimen is an adult (53.1mm SVL), possibly a female based on apparent lack of mental gland and lack of peramorphic or hypertrophied jaw musculature. The holotype exhibits the diagnostic greenish-grey ground color with a reddish-orange dorsal wash, orangish stripe with indistinct margins on the dorsal surface of the tail, yellowish or orangish portholes on the lateral surfaces in three rows, and granular ventral color-pattern with clusters of xanthophores and melanophores interspersed with white flecks and speckles.
