Fire‐induced disturbances in Malpighiaceae sequential flowering: Implications for pollination services and plant reproductive success

Plant Species Biology, EarlyView.
Our study demonstrates that fire has a strong influence on flowering phenology and reproductive dynamics in Malpighiaceae species from the Brazilian Cerrado. Specifically, fire triggered an earlier onset of flowering and promoted a more synchronous and widespread blooming, resulting in a temporary surge in floral resource availability. This increase in

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia

Insect Science, EarlyView.
This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.

Interspecific association of bumblebees (Hymenoptera, Apidae, Bombus) in Omsk region during the beginning of flight activity

Известия высших учебных заведений. Поволжский регион: Естественные науки, 2022
Background. Of great importance for bumblebees is the availability of a food base in two significant periods of life: at the beginning of flight activity after leaving wintering and at the end of flight activity in the period before wintering.

Stress in dipteran insects mass‐reared for sterile insect technique applications

Insect Science, EarlyView.
The connections between biotic and abiotic stress affecting mass‐reared dipteran insects and the associated stress and immunological responses. Numbers indicate the order in which the topics are discussed in this review. Abstract Stress may be viewed as the disturbance of homeostasis of an organism.

Longevity of starved bumblebee queens (Hymenoptera: Apidae) is shorter at high than low temperatures

European Journal of Entomology, 2014
Northern bumblebees (Hymenoptera: Apidae) with annual lifecycles depend both on energy stores remaining in their fat body after diapause and a few spring flowering plants.

Do Insects Have Emotions? Some Insights from Bumble Bees

Frontiers in Behavioral Neuroscience, 2017
While our conceptual understanding of emotions is largely based on human subjective experiences, research in comparative cognition has shown growing interest in the existence and identification of “emotion-like” states in non-human animals.

Special Issue: Food Sustainability, the Food System, and Alaskans [PDF]

, 2011
[Geography] -- The Alaska Food Policy Council: Everyone knows that food is important, but our dependence upon Outside for the stuff of life has finally begun to seem, well, just a little discomfiting to Alaska's policymakers.

Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps

Insect Science, EarlyView.
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...

Methylation and gene expression differences between reproductive and sterile bumblebee workers

bioRxiv, 2019
Phenotypic plasticity is the production of multiple phenotypes from a single genome and is notably observed in social insects. Multiple epigenetic mechanisms have been associated with social insect plasticity, with DNA methylation being explored to the ...

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.
