Fylogeneze východoafrických ještěrek rodu Latastia

Hlaváč, Denis

The East African genus Latastia is a taxon within the family Lacertidae, with a distribution covering a broad region of sub-Saharan Africa. This genus is relatively diverse and currently comprises ten recognized species. However, the morphology of these species is quite variable and often reflects the environmental conditions in which they occur. To date, no comprehensive molecular-level assessment of the genus's taxonomy has been conducted, leaving its classification unresolved. To address these outstanding questions, we reconstructed the first phylogeny of the genus Latastia, covering seven recognized species and five subspecies, with a total of 84 sequenced individuals. Phylogenetic trees were constructed from two datasets combining five mitochondrial (12S, 16S, COI, ND4, cytb) and four nuclear (c-mos, RAG1, RAG2, ACM4) markers, using Maximum Likelihood (ML) and Bayesian Inference (BI) analyses. These results were further supported by genealogical analyses of haplotype networks based on the four nuclear markers. The molecular results were subsequently visualized on maps illustrating individual phylogenetic lineages along with their inferred distribution ranges, including unsampled taxa. The molecular analyses support the expected hypothesis that phylogenetic conclusions differ from the currently...
