Precipitation‐mediated asymmetric fitness consequences of nectar robbing in distylous Primula florindae

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

Pollinator community composition and pollen resource use in calcareous grasslands under different landscape contexts across Europe

open access: yesJournal of Animal Ecology, EarlyView.
In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

open access: yesIntegrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.
