Summary: The study conducted a cytogenetic analysis on five out of the seven species of the genus Lyciasalamandra, revealing a high diversity in karyotype configuration and nucleolus organizing regions (NORs). The unique taxon-specific NOR configuration supports the taxonomic validity of different evolutionary lineages and suggests a scenario of synchronous evolution in the Lycian salamanders. The observed variability in NORs is likely derived from multiple independent translocations and inversions, contributing to lineage divergence in Lyciasalamandra.

Summary: A new species of the genus Tylototriton from Tongzi County, Guizhou Province, China was described, and its relationship with other species was determined using morphological characteristics and molecular phylogenetic analysis. It is suggested to classify this new species as Critically Endangered.

Summary: This study described the changes in skin structure during development in the Balkan crested newt. The skin in the larval stages consisted only of the epidermis, which developed into a stratified epidermis with glands and Leydig cells during late larval stage. Leydig cells disappeared during metamorphosis, and the dermal layer developed. In postmetamorphic stages, the skin differentiated into a stratified epidermis and well-developed dermis with various glands. The composition of the glands appeared to be stage- and sex-specific, with similarities between juveniles and adult females.

Summary: This study investigated the feeding habits of the Central Lineage of the Japanese fire-belly newt. It found that dipteran aquatic larvae were the most important food source for the newts, followed by terrestrial invertebrates. Shed skin could also be a valuable food source during periods of low prey availability. The study also highlighted the differences in prey selection between sympatric frogs and newts.

Summary: The Anderson's crocodile newt, a species endemic to the islands of Central Ryukyus, Japan, exhibits high intraspecific genetic variation among islands. However, little is known about its morphological variation. Using geometric morphometrics, we studied skull variation in this species and discovered sexual differences and geographic variation, particularly between the Okinawa group and the Amami Group. Interestingly, Taiwanese specimens showed strong resemblance to female specimens from Amamioshima Island.

Summary: In this study, we describe the morphology and conduct a phylogenetic analysis of the Tylototriton population in northern Thailand. The population was found in Doi Pha Hom Pok National Park and identified as Tylototriton verrucosus. The study confirms the range extension of this species in northern Indochina and discusses its morphological variation and conservation status.

Summary: Molecular divergence dating can help overcome the incompleteness of the fossil record, but it needs to be calibrated by fossil data. The current calibration dates cannot be relied on from published compendia or other secondary sources as they quickly become outdated.
