Research Interests

Lichens grow on nutrient poor soils or soil-less substrata, habitats that are abundant in heathlands, polar regions and arid lands. We are interested in ways in which lichens are adapted to these extreme environments (e.g. by the efficient capture and recycling of nutrients) and how they contribute to ecosystem function (e.g. by efficient scavenging of nutrients from the atmosphere and nitrogen fixation). The use of lichens as environmental monitors is also studied.

Current PhD students

Edward Tripp is studying the conservation of heathland vegetation.
