Global pollinator declines: trends, impacts and drivers.
Declines of managed honey bees and beekeepers in Europe
The data support the view that honey bees are in decline at least in some regions, which is probably closely linked to the decreasing number of beekeepers.
Honey bee colony losses
Examination of the historical record shows that such extensive colony losses are not unusual, and it is crucial to make beekeeping a more attractive hobby and a less laborious profession, in order to encourage local apiculture and pollination.
Isolation, identification and pathogenicity of Phytophthora species from declining oak stands
It could be shown in vitro that Phytophthora gonapodyides and Pythium group P were able to produce a wilting toxin.
Predictive Markers of Honey Bee Colony Collapse
The data show that DWV, Nosema ceranae, Varroa destructor and Vitellogenin can be predictive markers for winter colony losses, but their predictive power strongly depends on the season.

The findings strongly suggest that V. destructor and DWV reduce the life span of winter bees, thereby constituting a parsimonious possible mechanism for honeybee colony losses.
The biology of the small hive beetle (Aethina tumida, Coleoptera: Nitidulidae): Gaps in our knowledge of an invasive species
The knowledge of the small hive beetle is still limited, creating demand for more research in all areas of its biology, and it has the potential to become a global threat to apiculture and wild bee populations.

Sublethal neonicotinoid exposure did not provoke increased winter losses, yet significant detrimental short and long-term impacts on colony performance and queen fate suggest that neonicsotinoids may contribute to colony weakening in a complex manner.
Longevity and Reproductive Success of Aethina tumida (Coleoptera: Nitidulidae) Fed Different Natural Diets

Small hive beetle longevity and overall reproductive success was highest on foodstuffs located in honey bee colonies, indicating that A. tumida are efficient at causing large-scale damage to colonies of honey bees resulting in economic injury for the beekeeper.
Sublethal neonicotinoid insecticide exposure reduces solitary bee reproductive success

It is shown that chronic, dietary neonicotinoid exposure has severe detrimental effects on solitary bee reproductive output, and present pesticide risk assessments need to be expanded to include whole life‐cycle fitness estimates, as demonstrated in the present study using O. bicornis as a model.
