Karin Hårding - Associate Professor

Research interests

I’m interested in aspects of population biology and evolutionary biology, and in particular the interface between these two fields. How do environmental factors influence life histories and thereby population dynamics? How are population growth and extinction risk influenced by population structure? I work with empirical data from seal populations and with theoretical approaches.

Photo: Ken Howard.Within a long term project on harbour seals we study how age and sex structure together with behaviour, influence the development of the population (Refs 2,5,6). This knowledge is now useful as we try to understand the dynamics of the recent mass mortality of harbour seals caused by Phocine Distemper Virus (Ref 8,9,10).

We have developed a simplified framework for metapopulation models. It allows for many different functional relationships between immigration and local population dynamics (Ref. 7). This approach is now extended to study the dynamics of invasive species in patch networks.
