(Asteraceae), in the Páramo de Sumapaz (Colombia) General Research Interests I am interested in understanding the determinants of the abundance and distribution of organisms at a variety of spatial scales, ranging from the small extents on which foraging theory focuses, to the broad geographic extents characteristic of macroecology Research Emphases I am currently focusing on testing theory that attempts to explain spatial patterns of diversity and the size, structure and dynamics of geographic ranges of taxa. Spatial patterns of diversity are expressions of how the geographic ranges of taxa overlap. Understanding these patterns is central to the practice of conserving biodiversity. Specifically, spatial patterns of diversity (including richness, endemism and taxa turnover) determine how limited resources for the conservation of biodiversity should be distributed spatially to obtain the highest yield in terms of number of taxa protected (or other biodiversity metrics such as phylogenetic diversity). Furthermore, studies on the determinants of diversity patterns provide insights that help inform the conservation and management of ecological and evolutionary processes responsible for the creation and maintenance of biodiversity patterns Selected Publications Sheth, S., T.
