Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

A Tale of Appendages: Investigating Limb and Tail Variation in Salamanders

Integrative Zoology, EarlyView.
We analyzed limb and tail proportions in 44% of known salamander species using a phylogenetic comparative approach. Our results revealed significant variation among families and ecological groups, with aquatic species showing longer limbs and basal lineages having shorter tails.

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...
