Area‐restricted search under realistic constraints

Oikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Acetamiprid Exposure Disrupts Gut Microbiota in Adult and Larval Worker Honeybees (Apis mellifera L.)

Insects
Acetamiprid is a third-generation neonicotinoid insecticide that is now widely employed for the protection of crops grown in outdoor environments. This is because it is considerably less toxic to pollinating insects than other neonicotinoids.

Phylogenetic analysis of the honeybee Sacbrood virus

Journal of Apicultural Science, 2016
Sacbrood virus (SBV) is one of the most common and harmful viruses to honeybees. It causes failure to pupate and death during larval stage, in adult bees it has an influence on their behavior and even shortens their life-span.

EFFECTS OF C60 FULLERENE — CISPLATIN COMPLEX ON HONEYBEE Apis mellifera L. [PDF]

Biotechnologia Acta, 2015
The toxicity of С60 fullerene, traditional cytostatic cisplatin and С60 fullerene-cisplatin complex on honeybee Apis mellifera L. toxicity estimation test system was assessed. Water-soluble pristine C60 fullerenes were nontoxic for honeybee when consumed

The role of UV in crab spider signals: effects on perception by prey and predators [PDF]

, 2005
Australian crab spiders Thomisus spectabilis sit on the petals of flowers and ambush prey such as honeybees. White-coloured T. spectabilis reflect in the UV (UV+ spiders) and previous research has shown that their presence, curiously, attracts honeybees ...

Pathogen shifts in a honeybee predator following the arrival of the Varroa mite

Proceedings of the Royal Society B, 2019
Emerging infectious diseases (EIDs) are a global threat to honeybees, and spillover from managed bees threaten wider insect populations. Deformed wing virus (DWV), a widespread virus that has become emergent in conjunction with the spread of the mite ...

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Revealing Changes in Ovarian and Hemolymphatic Metabolites Using Widely Targeted Metabolomics between Newly Emerged and Laying Queens of Honeybee (Apis mellifera)

Insects
The queen bee is a central and pivotal figure within the colony, serving as the sole fertile female responsible for its reproduction. The queen possesses an open circulatory system, with her ovaries immersed in hemolymph.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

The mechanism of Andrena camellia in digesting toxic sugars

iScience
Summary: Camellia oleifera is an economically and medicinally valuable oilseed crop. Honeybee, the most abundant pollinator, rarely visits C. oleifera because of the toxic sugars in the nectar and pollen.
