We will host Prof. Dr. Donald L. Swiderski, and Prof. Dr. M. Zelditch for a period of one week at Koç University from 01 to 08 May 2023. After a one-day seminar on analyzing mammalian macro-evolution, Dr. Swiderski, and Dr. M. Zelditch will hold a course on geographic analysis of biodiversity (integrating geographic, shape, and phylogenetic data) on the following days of the week. In this course instructors will introduce different conceptual biological reasons why it might be interesting to examine biodiversity data in a geographic context, focusing on the relationships between species richness, trait similarity, and phylogeny, as well as patterns of turnover in those relationships. In this overview, they will discuss what these can reveal about patterns of community assembly, in situ diversification vs immigration, as well as the potential connections between these patterns and environmental/climatic/elevational gradients.

I am an evolutionary biologist interested primarily in the relationship between morphological changes and functional transitions in both evolution and ontogeny. I use quantitative analyses of skeletal shape data to gain a better understanding of (a) what morphological attributes actually differ between species or growth stages in different ecological roles, and (b) the relevance of morphological change to functional or ecological change. My recent research has focused on the relationship between diversity and disparity in squirrels, using quantitative analyses of jaw shape. I also am interested in locomotion and the relationship between locomotory and dietary transitions, and in form-function relationships throughout the animal kingdom.

I am an evolutionary biologist interested in the relationship between diversification and morphological evolution. The geographic landscape is central to theories of diversification, and the adaptive landscape is equally central to theories of adaptive evolution, so integrating these two landscapes promises a general theory for the generation and maintenance of diversity of both species and their morphologies. I use models of adaptive evolution, combined with geographic distributions of species and their morphologies, to analyze the relationship between species richness and morphological diversity over time and space.
