Causes of colony mortality in bumblebees [PDF]
, 2017 Despite considerable interest in bumblebees and their conservation, few data are available on basic life-history parameters such as rates of nest predation and the proportion of wild nests that survive to reproduction.

ParasitologyBees are key species for pollination and apiculture. Within the multiple biotic threats, parasites are one of the main players involved in bee health. Among them, trypanosomatid parasites have been the focus of recent studies that have placed them as one

Memory Matters: Bumblebee Behavioral Models for Vehicle-to-Vehicle Communications
IEEE Access, 2018 Vehicles forming connected communication networks are routinely challenged with the complex decision problem of either staying with the same wireless channel or moving to a different wireless channel when experiencing highly variable channel quality ...

Journal of Zoology, EarlyView.The Urban Heat Island Effect (UHI) can potentially subject insects to heat and desiccation stress and likely induce shifts in their cuticular hydrocarbon (CHC) profile. We expected that warmer urbanized areas favour longer chain length of hydrocarbons as well as higher abundance of n‐alkanes in three Hymenoptera species. We found that temperature, more

Declines in forage availability for bumblebees at a national scale
, 2006 We assessed national scale changes in the forage plants of bumblebees in Britain, as a means of providing quantitative evidence for the likely principal cause of declines in bumblebee species.

Gustatory sensitivity to amino acids in bumblebee mouthparts
Royal Society Open ScienceBees rely on amino acids from nectar and pollen for essential physiological functions. While nectar typically contains low (less than 1 mM) amino acid concentrations, levels in pollen are higher but variable (10–200 mM).

Rapid disruption of pollination function by the invasive plant Impatiens glandulifera
Plant Biology, EarlyView.Invasion by Impatiens glandulifera rapidly disrupts pollination of the native plant Stachys sylvatica by altering pollen transport by shared bumblebee pollinators. A short‐term field introduction revealed a dramatic decline in conspecific pollen deposition within 4 days, showing that pollination function can collapse quickly following invasion, even ...

The value of uncropped field margins for foraging bumblebees
, 2001 The intensification of agriculture has led to declines in species diversity and abundance within groups of certain flora and fauna. Bumblebees (Bombus spp.) are one group where a decline has been documented, and it is thought to be attributable to a ...

Plant Biology, EarlyView.Expression of genetic differences depends on the experimental environment as seen in flowering time differences between ancestors and descendants that emerge in climate chambers but not in greenhouse or garden conditions. Abstract Common‐environment experiments are important to study genetically based phenotypic variation within and among plant ...

Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?
Topics in Cognitive Science, EarlyView.Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...
