          Abstract

          Two previously known northernmost localities of Sharp-snouted rock lizard in Montenegro were the entrance of the Komarnica Canyon (Nevidio), and the middle part of the Tara River Canyon (village Tepca). It was presumed that Komarnica and Piva canyons were once corridors for the spreading of this species from the Eastern Adriatic sub-Mediterranean area to the Tara River Canyon in the north. However, it had not been hitherto known if there were any other relict populations in the area. In the autumn of 2019 a localized population of D. oxycephala was discovered in the middle part of the Komarnica Canyon.

            Environmental temperatures shape thermal physiology as well as diversification and genome-wide substitution rates in lizards

            Climatic conditions changing over time and space shape the evolution of organisms at multiple levels, including temperate lizards in the family Lacertidae. Here we reconstruct a dated phylogenetic tree of 262 lacertid species based on a supermatrix relying on novel phylogenomic datasets and fossil calibrations. Diversification of lacertids was accompanied by an increasing disparity among occupied bioclimatic niches, especially in the last 10 Ma, during a period of progressive global cooling. Temperate species also underwent a genome-wide slowdown in molecular substitution rates compared to tropical and desert-adapted lacertids. Evaporative water loss and preferred temperature are correlated with bioclimatic parameters, indicating physiological adaptations to climate. Tropical, but also some populations of cool-adapted species experience maximum temperatures close to their preferred temperatures. We hypothesize these species-specific physiological preferences may constitute a handicap to prevail under rapid global warming, and contribute to explaining local lizard extinctions in cool and humid climates.
