Article Synopsis
- Cryptic diversity in species like Mediodactylus complicates biodiversity assessments and conservation, with past taxonomic changes highlighting hidden species.
- Recent research identified five distinct species within the M. kotschyi complex using advanced genetic techniques, revealing some are endemic and possibly threatened.
- A large-scale genomic analysis uncovered complex phylogenetic relationships and significant genetic differentiation among populations, suggesting the presence of even more undescribed species.
Ectotherms, including lizards, rely on behavioral thermoregulation to maintain their body temperature within an optimal range. The benign climate of islands is expected to favor the thermoregulation efficiency of reptiles throughout their activity period. In this study, we investigated the seasonal variation in thermoregulation in an insular population of the roughtail rock agama () on Naxos Island, Greece.

- * Mitochondrial DNA studies have categorized these species into two main subgroups: "P. tauricus" and "P. erhardii," highlighting the genetic relationships among them.
- * By using advanced genetic sequencing methods, researchers confirmed the existence of all recently recognized species and identified at least two additional species within the groups, suggesting a need for re-evaluating the taxonomy of Podarcis in this region.
Lacertid lizards are a widely radiated group of squamate reptiles with long-term stable ZZ/ZW sex chromosomes. Despite their family-wide homology of Z-specific gene content, previous cytogenetic studies revealed significant variability in the size, morphology, and heterochromatin distribution of their W chromosome. However, there is little evidence about the accumulation and distribution of repetitive content on lacertid chromosomes, especially on their W chromosome.

- * Researchers studied wall-lizard species from the region to understand their evolutionary processes using various genetic analysis methods.
- * Their findings revealed distinct evolutionary lineages and showed that significant climatic and tectonic events influenced species divergence and genetic diversity.
