'Carabidologists do it all' (Niemelä 1996a) is a phrase with which most European carabidologists are familiar. Indeed, during the last half a century, professional and amateur entomologists have contributed enormously to our understanding of the basic biology of carabid beetles. The success of the field is in no small part due to regular European Carabidologists' Meetings, which started in 1969...
Bryophytes are widely used in monitoring environmental changes and various types of pollution. Features such as longevity direct intake by the whole body make them very good models for bioindication. However, there is a considerable lack knowledge on coping, resistance tolerance mechanisms to toxic elements within representatives this second largest group terrestrial plants. We tested two diffe...
