Zachary MacDonald, Ph.D.
Assistant Professor of Conservation Genomics and Biodiversity
UC Riverside Department of Entomology
Zachary MacDonald is broadly interested in ecological and evolutionary mechanisms that structure biodiversity in space and time. Throughout his Ph.D. at the University of Alberta, much of Zac’s work focused on conservation applications of theoretical ecology, evaluating relationships between habitat loss, habitat fragmentation, and emergent patterns of species diversity and genetic diversity. During his La Kretz Center Postdoctoral Fellow in the Shaffer Lab, Zac focused on evaluating effects of habitat and climate changes on a reduced number of species, but in greater detail. This involved equal parts of: (1) forward-in-time landscape and environmental modelling, to map habitat suitability and connectivity, and predict how they will change under different climate change scenarios; and (2) population genomics, to quantify population structure, genetic diversity, and inbreeding depression within species. This has proven valuable for conserving many endangered and at-risk butterfly species throughout western North America, often working closely with regulatory agencies to develop adaptive management strategies that translate science into policy.
In 2025, Zac joined UC Riverside’s Department of Entomology as an Assistant Professor of Conservation Genomics and Biodiversity.
