Flower Constancy of Bumblebees – The Case of Onobrychis pindicola (Fabaceae) Pollinators
Journal of Apicultural Science, 2018 Pollination in high mountain habitats is an important ecosystem service in climate change conditions. The aim of this study was to use pollen load analysis to assess flower constancy and foraging choices of bumblebees foraging on Onobrychis pindicola, a ...

The bumble bees (Hymenoptera: Apidae: Bombus) of Arkansas, fifty years later [PDF]
, 2015 Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking. In the present study, contemporary data

Continuous Radar Tracking Illustrates the Development of Multi-destination Routes of Bumblebees
Scientific Reports, 2017 Animals that visit multiple foraging sites face a problem, analogous to the Travelling Salesman Problem, of finding an efficient route. We explored bumblebees’ route development on an array of five artificial flowers in which minimising travel distances ...

Ecological change may be a common initiator of evolutionary pollinator shifts
New Phytologist, EarlyView.Summary Although evolutionary pollinator shifts are accepted as major sources of floral and species diversity in angiosperms, the mechanisms triggering pollinator shifts remain largely unexplored. In 1970, Stebbins proposed that ecological change may be a common initiator of evolutionary pollinator shifts, but empirical tests of Stebbins' hypothesis ...

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 ...

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 ...

Measurement of electric charges on foraging bumblebees (Bombus terrestris)
Journal of Physics: Conference Series, 2019 Bumblebees carry electric charge. Almost always positive, this charge facilitates pollen transfer between bumblebee and flower during pollination and is likely to play a role in the detection of electric fields.

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 ...

Przestrzenne i czasowe zróżnicowanie Apoidea w lasach Wielkopolskiego Parku Narodowego [PDF]
, 1994 Results of the investigations of spatial and temporal differentiations of Apoidea in the forests of Wielkopolski National Park were presented. It was shown that the both forest floor differ with the degree of species differentiation and domination’s ...
