Foraging energetics reveals late‐summer challenges for pollinators across two British cities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

First molecular detection of co-infection of honey bee viruses in asymptomatic Bombus atratus in South America

Brazilian Journal of Biology
Pollination is critical for food production and has the particularity of linking natural ecosystems with agricultural production systems. Recently, losses of bumblebee species have been reported worldwide.

Warming and community context drive rapid plant evolution

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Abiotic and biotic factors are important drivers of plant evolution, but how these factors interact to influence plant evolution in multispecies communities is still poorly understood. We performed experimental evolution exposing Brassica rapa plants to a combination of

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

Functional 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.

Effects of Bacillus thuringiensis subsp. aizawai GC91 (Agree WG) on R&D colonies of the buff-tailed bumblebee Bombus terrestris : (2.5 Part 2)

Julius-Kühn-Archiv, 2020
Bacillus thuringiensis subsp. aizawai, a widely used biological plant protection product, was tested on buff-tailed bumblebee Bombus terrestris, using an updated laboratory method on full standardized R&D colonies.

Pollen from multiple sunflower cultivars and species reduces a common bumblebee gut pathogen [PDF]

Royal Society Open Science, 2019
Pathogens are one of the factors driving pollinator declines. Diet can play an important role in mediating pollinator health and resistance to pathogens. Sunflower pollen (Helianthus annuus) dramatically reduced a gut pathogen (Crithidia bombi) of Bombus

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.

Assessing the efficacy of artificial domiciles for bumblebees

, 2011
Bumblebees have suffered declines as a result of reduction in habitat availability associated with agricultural intensification. Although several conservation strategies for bumblebees address forage availability, other aspects of bumblebee ecology are ...

Effects of chemical and biological plant protection products on R&D colonies of the buff-tailed bumblebee Bombus terrestris : (2.5 Part 1)

Julius-Kühn-Archiv, 2020
Bumblebees (Bombus terrestris) are exposed daily to Plant Protection Products through their foraging and feeding activities. Through all possible means of contact with pesticides, consumption through sugarwater is the most severe.

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.
