Summary
Abstract
We provide an overview of trends and uncertainties emerging from the growing field of climate change and biodiversity research using lichens as a study group. Problems in understanding the implications of global change for lichens are relevant to other groups comprising subdominant species such as algae, mosses and liverworts. Ecological study of lichens represents a diverse range of the ascomycete fungi, which have adopted a strategy in symbiosis with an inhabitant autotrophic partner. In general lichens may be considered ‘stress tolerators’, although contrasting lichens encompass a range of life histories with respect to reproduction, dispersal and habitat specialisation. Lichens typically occupy microhabitats nested within a larger-scale habitat mosaic and are relatively little studied compared to vascular plants and animals. We examine two main themes: (1) the direct effect of climate warming on lichens with respect to arctic–alpine ecosystems; and (2) the indirect effect of climate change on lichens resulting from interaction with other environmental factors. Within this framework we discuss the current limits to bioclimatic modelling, the role of molecular ecology in climate change studies, species interactions, and opportunities for conservation in the face of climate change uncertainty. We draw on research from across geographic regions, with several focused examples referring to lichens in Britain and Ireland, which have the advantage of being among the best-explored lichen floras in the world.
