Scientists are becoming increasingly concerned over the increasing number of species that are becoming extinct, with some researchers claiming that we are in the midst of the sixth mass extinction on planet earth.
Professor Andy Purvis from Imperial College in London will talk about how estimates of past and present biodiversity are made, how rates of species decline and extinction can be calculated and even how future extinction risk can be predicted.
Professor Purvis will draw upon his research into large-scale patterns and processes in biodiversity and the evolutionary relationships among species.
At another lecture the following week, (12 October 2005) Mark Corney will give an update on the excavation of two roman villas discovered in Bradford-on-Avon in 2002.
Admission for both lectures is free, just turn up on the evening. Free parking available in the West Car Park. All lectures run from 5.15pm until 6.15pm.
