Blind mole rats (BMR) of the genus Nannospalax are subterranean rodents known for their longevity, cancer resistance, and extreme chromosomal diversity, with 74 chromosomal forms (CFs). Despite being extensively studied, their taxonomy and phylogeny remain unclear due to convergent morphology and chromosomal speciation. Only three superspecies (N. leucodon, N. xanthodon, and N. ehrenbergi) are recognized by the IUCN as Data Deficient, though they likely encompass numerous cryptic species at risk from habitat loss. This project aims to resolve BMR taxonomy and phylogeny using a comprehensive 3D geometric morphometric (GM) analysis of mandibles and crania, combined with molecular data. By applying phylogenetic comparative methods, the study will explore size and shape variation, allometry, morphological integration, and modularity across CFs. Data will be analyzed using MorphoJ software and R. The 24-month project includes fieldwork, karyotyping, 3D data collection, and collaborative study of South-Eastern European and Anatolian populations. Outcomes include a large digital database of 3D models and insights into evolutionary significant units (ESUs), potentially contributing to the IUCN Red List designation and conservation of cryptic species.
