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?

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

Oikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

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.

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

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.

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.

Honeybees Learn Odour Mixtures via a Selection of Key Odorants [PDF]

, 2015
BACKGROUND The honeybee has to detect, process and learn numerous complex odours from her natural environment on a daily basis. Most of these odours are floral scents, which are mixtures of dozens of different odorants.

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 ...
