Abstract

The comparison of palaeoenvironmental and archaeological records of fossil insects with modern red data books can provide a picture of local extinctions. Buckland & Buckland (2012) performed such a study on the Coleoptera of the British Isles, using the BugsCEP database for the fossil data, and looking at broad chronological divisions. The ecology of these regionally extinct beetles, all of which are extant in other parts of the World, may be used to investigate the environmental and climatic changes which may have lead to their extirpation. This process can be semi-automated and habitats quantified through the use of ecological classification and a database infrastructure which links fossil and modern ecological and climate data (Buckland & Buckland 2006; http://www.bugscep.com). Preliminary results indicate that the majority of extirpated species with mid-Holocene records were dependent on woodland environments (Buckland 2014). These investigations can be refined by using narrower time-slices, interpolating dating evidence and including more comprehensive archaeological dating evidence. The expansion of the analysis to include the full assemblages found in the samples containing the extirpated species also allows for a more comprehensive picture of the long-term relationships between biodiversity, environmental and climatic change and human activity.Abstract will be published in conference abstract volume.BugsCE
