3D Cranial Morphometry, Sensory Ecology and Climate Change in African Rodents
My current project, conducted under the supervision of Pr. J. Braga (University Toulouse III, Paul Sabatier) and Pr. P.J Taylor (University of Venda) primarily focuses on investigating temporal changes in both cranial size and shape of selected African rodent species from different environments and life histories (e.g. from different biomes from grassland to desert and from herbivores to seed-eaters, as well as from commensal species living in close proximity to humans as well as those species occurring only in specialized habitats). As a sub-theme, the study is also exploring the functional basis of inner ear, endocranium, dentine and auditory bullae in desert and mesic Otomyinae and Gerbillinae rodents (and whether these structures have been affected by climate change and associated vegetation/ environmental changes). There is an emerging body of research in this important field, often termed the "third universal response to global warming", but nothing has been done in Africa, and studies to date have focused only on size changes, neglecting the important component of cranial shape. The project will use both more effective cutting-edge geometric morphometric technology (Micro-CT scanners) and excellent historical series of specimens in France (Paris Museum of Natural History), and South Africa (Ditsong Museum of Natural History, Pretoria and Durban Natural History Museum).
