Genetic variation and demographic history of Sudan desert sheep reveal two diversified lineages (2023)
Journal Article

More than 400 million sheep are raised on the African continent, the majority of which are indigenous and are primarily reared for sustenance. They have effectively adapted to various climatic and production environments, surviving and flourishing. T...

Analysis of tail morphology and osteology in Ethiopian indigenous sheep (2023)
Journal Article

Sheep adaptive diversity, including tail morphology, has been shaped by various factors, including natural and/or artificial selection for different traits. The Horn of Africa has historically been a major livestock entry point on the African contine... Read More about Analysis of tail morphology and osteology in Ethiopian indigenous sheep.

Morphological and osteological characterization of indigenous domestic chickens (Gallus gallus domesticus): validation of Rensch’s, Bergmann’s and Allen’s rules (2023)
Journal Article

Ecogeographical habitat heterogeneity in wild endotherm species results in morphological variability associated with physiological mechanisms for maintaining their body temperature at a thermoneutral state in different environments. This habitat-indu... Read More about Morphological and osteological characterization of indigenous domestic chickens (Gallus gallus domesticus): validation of Rensch’s, Bergmann’s and Allen’s rules.
