The Role of Landscapes and Landmarks in Bee Navigation: A Review. [PDF]
, 2019 The ability of animals to explore landmarks in their environment is essential to their fitness. Landmarks are widely recognized to play a key role in navigation by providing information in multiple sensory modalities. However, what is a landmark?

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success
Insect 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.

Field-level clothianidin exposure affects bumblebees but generally not their pathogens
Nature Communications, 2018 Neonicotinoids are implicated in bee declines and laboratory studies imply that they impair the bee immune system, thereby precipitating a rise in pathogen levels.

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior
Integrative 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.

Organic farming supports spatiotemporal stability in species richness of bumblebees and butterflies
Biological Conservation, 2018 The spatiotemporal stability of wild organisms, such as flower-visiting insects, is critical to guarantee high levels of biodiversity in agroecosystems.

Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.
