Auswirkungen des Klimawandels auf die Evolution von Körpergröße in Großsäugern des späten Känozoikums
Zusammenfassung der Projektergebnisse
This project took a historical perspective for understanding the relationship between body size evolution and environmental changes. My investigation on the land mammal fossil record identified a critical, indirect impact of climate change, mediated by habitat transition on the evolution of body size. My work highlights the value of integrating evolutionary history with ecological functions and environmental history in understanding the animal evolution. I expanded my investigation to modern mammals to take advantage of the rich literature on their ecological behaviors and geographic distributions. My finding of a strong link of body size to diet breadth and foraging range further emphasizes the ecological drivers of body size evolution and a critical role of resource availability in shaping mammal diversity patterns. Overall, my findings are particularly relevant to mitigating the current biodiversity crisis as humans continuously modify the global environment, including habitats for modern animals. My findings about the body size evolution and more generally, biodiversity dynamics in land mammals has inspired me to expand my research to other organismal systems, including the diversity of parasites infecting wild mammals. For example, one collaborative project compared the body size trends in parasitic helminths and their host mammals across environmental gradients and found contrasting links to climatic conditions. I also contributed my analytical experience with the fossil record to the development of general methods for estimating diversity from incomplete samples such as for the diversity of parasitic organisms. Through these interdisciplinary collaborations, my work has highlighted the value and relevance of paleobiology.
