We are offering unique MSc and PhD projects on the eco-evolutionary and conservation dynamics of Lithops spp., a genus of small succulent plants occurring across desert landscapes in southern Africa. In the wild, Lithops are susceptible to habitat loss, climate change and poaching, and currently there are important knowledge gaps related to Lithops phylogeny and ecology that are impacting conservation status assessment and protection. The project involves several critical facets, first consisting of Lithops genome sequencing to support re-assessment of genus phylogeny and evolutionary linkages, as well as garden experiments to understand Lithops resiliency and epigenetics in the face of climate change. Collectively, these efforts will identify distinct Lithops groups, determine those that should receive high conservation priority, and inform on the best candidates for population restoration in their native habitat. In the field, we are pursuing a variety of directions including: 1) Helping develop a long-term monitoring program for Lithops populations; 2) Using remote sensing to assess plant health and composition in relation to local environmental conditions; 3) Testing population survey methods, habitat suitability needs, and potential for recolonization; 4) Assess population and meta-population viability to model scenarios for long-term persistence; and 5) Conduct species distribution modeling to better understand potential responses of populations to climate change. The model for much of the fieldwork will be L. schwantesii, which is among the most widespread and best-studied Lithops species in Namibia. The specific graduate project(s) will be tailored according to student interests and larger project needs. 

Successful candidates MUST have a BSc in Biology, Ecology, or related field, with PhD applicants also needing an MSc degree and demonstrated evidence of peer-reviewed publications. Students with good lab or field skills, and an interest in working collaboratively within a large and diverse research group are especially sought. Additional desirable qualifications include DNA sequencing, bioinformatics, remote sensing and GIS analysis, and working in remote field conditions.
