In human-wildlife conflicts, it is crucial to develop accurate protocols for the reliable verification of causative species and its relationship with potential damage claims. One such conflicts that occurring between apiarists bee-eaters. this work, we aim assess utility passive acoustic monitoring (PAM) as an efficient methodology measure European bee-eater (Merops apiaster) predation pressure...
The effect of environmental pollutants on honeybee behaviour has focused mainly on currently used pesticides. However, honeybees are also exposed to persistent organic pollutants (POPs). The aim of this laboratory based study was to determine if exposure to sublethal field-relevant concentrations of POPs altered the spontaneous behaviour of foraging-age worker honeybees. Honeybees (Apis mellife...

The loss of Apis mellifera L. colonies in recent years has, in many regions of the world, been alarmingly high. No single cause has been identified for these losses, but the interactions between several factors (mostly pathogens and parasites) have been held responsible.
