Description:This book, dedicated to Professor Emeritus George Ball from the University of Alberta, Canada, presents a collection of 30 papers held at the XIII European Carabidologists Meeting in Blagoevgrad, Bulgaria (August, 2007). The meeting was attended by 90 specialists from 20 countries of Europe, Asia and America. Traditionally, the proceedings volumes of the European Carabidologists Meeting have become important milestones outlining the latest trends and achievements in carabidology. The aim of the organisers was to invite specialists from different countries and scientific schools to attempt most complete representation of both traditional and innovative approaches and methods in studying ground beetles.
