Genetics & ...

Rare Species: "The Anna Karenina principle states that “Happy families are all alike; every unhappy family is unhappy in its own way”

When we talk about rare species we tend to think of them as a collective group that shares similar traits, however, some argue that “every rare species is rare in its own way”. Rabinowitz (1981) showed that all common species had wide ranges, large population and broad habitat tolerance, while rare species could have any combination of these traits, but not all three. What is interesting is the range, population size and habitat preference all have important consequences for gene flow and population structure.

I am interested in the population genetics of rare species, and what that can tell us for about the management of these species.

Botanic Gardens: "Botanic Gardens are playing a growing role in plant conservation"

Botanic Gardens collections are playing an important role in helping to slow the extinction of plant species. A well-planned collection will represent the complete genetic diversity of plants in the wild. Once we brought that diversity in our collections, our job is to ensure that the diversity is maintained, so that it could one day be used to return the plant back to the wild. 

Pollinators: "One of the few things that is as fascinating as the diversity of flowers, is the diversity of animals that pollinate them"

The success and diversity of flowering plants are attributed in part to animal pollination. The genetic contribution of different pollinator guilds will vary through maternal fitness (number of seed sired), paternal fitness (number of fathers and distance of fathers) and connectivity between isolated populations. I am interested in the role pollinators play in driving the genetic structure of plant populations.

Restoration: Choosing "genetically appropriate material" for restoration has become an important aim of many restorations.

I study the genetic, demographic, and community factors that might influence restoration success in a number of species. More specifically identifying what genetic factors could help improve the establishment and persistence of restored populations in long-term
