Karyological Diversification in the Genus Lyciasalamandra (Urodela: Salamandridae) [PDF]
Animals, 2021 We performed the first cytogenetic analysis on five out of the seven species of the genus Lyciasalamandra, including seven subspecies, and representatives of its sister genus Salamandra. All the studied species have a similar karyotype of 2n = 24, mostly

Hydrodynamics and Aquatic Vegetation Drive Spatial Patterns of Environmental DNA in Ponds
Environmental DNAEnvironmental DNA (eDNA) sampling is a powerful method for detecting aquatic species at low densities. However, eDNA may remain close to the source in lentic systems, decreasing the effectiveness of eDNA surveys.

The changing views on the evolutionary relationships of extant Salamandridae (Amphibia: Urodela). [PDF]
PLoS ONE, 2018 The phylogenetic relationships among members of the family Salamandridae have been repeatedly investigated over the last 90 years, with changing character and taxon sampling. We review the changing composition and the phylogenetic position of salamandrid

Gonadal Development in Larvae of the Paedomorphic Ambystoma mexicanum (Amphibia: Urodela). [PDF]
J MorpholThis research analyzes the gonads of Ambystoma mexicanum larvae of both sexes, revealing significant changes such as the onset of vitellogenesis in females at 9 months of age and oocytes with signs of maturity at 12 months. In males, gonadal maturity occurs earlier, with a notable cephalocaudal and lateromedial testicular regionalization, and ...
