Estimating Indirect Effects in a Wild and Anti-Social Mammal

Explore the fascinating world of indirect genetic effects in wild animals through this seminar presented by David Fisher from the University of Guelph. Delve into the study of North American red squirrels (Tamiasciurus hudsonicus) to understand how conspecific interactions can influence phenotypes and potentially alter evolutionary trajectories. Learn about the methods used to estimate indirect phenotypic and genetic effects among spatial and temporal neighbors in these wild and relatively anti-social mammals. Discover how population density impacts the strength of indirect effects and examine the potential consequences for trait evolution. Gain insights into the challenges of quantifying indirect genetic effects in wild populations and the importance of considering these effects in various ecological systems. Analyze the findings related to food hoard size and breeding date influences from previous territory holders. Understand the implications of this research for our broader understanding of evolution and adaptive potential in wild animal populations.
