Researchers create first map of bee species around the globe
There are over 20,000 species of bee, but accurate data about how these species are spread across the globe are sparse. However, researchers reporting in the journal Current Biology on November 19 have created a map of bee diversity by combining the most complete global checklist of known bee species with the almost 6 million additional public records of where individual species have appeared around the world.

Solitary bees are born with a functional internal clock - unlike honeybees
Individuals of the solitary bee Osmia bicornis show a 24-h behavioral cycle as soon as they emerge, unlike young honeybee workers who need to perform brood care around the clock and only develop a daily cycle later in life. This is reflected in a difference in the rate of brain development: in O. bicornis, but not in honeybees, neurons producing the ''pacemaker'' neuromodulator PDF are already maximally active immediately upon emergence. Sociality seems to have promoted a delay in maturation of the internal clock. (2020-11-16)

Beetles cooperate in brood care
Ambrosia beetles are fascinating: they practice agriculture with fungi and they live in a highly developed social system. Biologist Peter Biedermann has now discovered new facts about them. (2020-11-04)

Leaf-cutter bees as plastic recyclers? Not a good idea, say scientists
Scientists have noted instances of leaf-cutter bees using plastic waste to construct their nests and one research group suggested such behavior could be an 'ecologically adaptive trait' and beneficial recycling effort. Utah State University scientist Joseph Wilson says no; such behavior is harmful to the bee's offspring. (2020-11-03)

First Australian night bees recorded foraging in darkness
Australian bees are known for pollinating plants on beautiful sunny days, but a new study has identified two species that have adapted their vision for night-time conditions for the first time. The study by a team of ecology researchers has observed night time foraging behaviour by a nomiine (Reepenia bituberculata) and masked (Meroglossa gemmata) bee species, with both developing enlarged compound and simple eyes which allow more light to be gathered when compared to their daytime kin.

Burt's Bees presents clinical data on brand's natural lip and anti-aging skincare efficacy
Burt's Bees, a pioneer in natural skin care, today announced new research supporting the role of efficacy-first, natural regimens to defend, replenish and restore vibrant, healthier-looking skin. The studies will be presented at the virtual Integrative Dermatology Symposium (IDS) from October 23 - November 1, 2020. (2020-10-23)

Genome sequencing shows climate barrier to spread of Africanized bees
Since the 1950s, ''Africanized'' honeybees have spread north and south across the Americas until apparently coming to a halt in California and northern Argentina. Now genome sequencing of hundreds of bees from the northern and southern limits shows a gradual decline in African ancestry across hundreds of miles, rather than an abrupt shift. (2020-10-21)

Bark beetle outbreaks benefit wild bee populations, habitat
Researchers found significant increases in floral abundance and wild bee diversity in outbreak-affected forests, compared to similar, undisturbed forest. (2020-10-15)

'Honey bee, it's me'
Honey bees rely on chemical cues related to their shared gut microbial communities, instead of genetic relatedness, to identify members of their colony. This new work is significant in part because it shows an integral role for the microbiome in the essential, everyday social interactions of honey bees, the Earth's most important pollinators, researchers said. (2020-10-14)

Pollinator monitoring more than pays for itself
Study found pollinator monitoring schemes, which often combine expert and volunteer observations, provide high-quality scientific data at a far lower cost than individual research projects. (2020-10-08)

Native milkweed cultivars planted by the public can support monarch butterflies and bees
Millions of people plant pollinator gardens in an effort to provide monarch butterflies with food along their annual migration route from overwintering sites in the highland forests of central Mexico to summer breeding grounds in the United States and southern Canada. For the first time, entomologists studied how effective native milkweed cultivars in small gardens are at attracting and supporting monarchs - their results suggest that this can be a valuable additional food source. (2020-10-07)

Pesticides and food scarcity dramatically reduce wild bee population
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers at the University of California, Davis, found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring. (2020-10-06)

Plant droplets serve as nutrient-rich food for insects
Small watery droplets on the edges of blueberry bush leaves are loaded with nutrients for many insects, including bees, wasps and flies, according to a Rutgers-led study, the first of its kind. The study, published in the journal Proceedings of the Royal Society B: Biological Sciences, suggests that these droplets are an important but underexplored feature in plants, with profound implications for insects in agricultural and natural ecosystems. (2020-09-29)

Two pesticides approved for use in US harmful to bees
A previously banned insecticide, which was approved for agricultural use last year in the United States, is harmful for bees and other beneficial insects that are crucial for agriculture, and a second pesticide in widespread use also harms these insects. That is according to a new analysis from researchers at The University of Texas at Austin. (2020-09-29)

Similarities and dissimilarities between automatic learning in bees and humans
This study provides the first systematic comparison of automatic visual learning in humans and honeybees, showing that while both species extract statistical information about co-occurrence contingencies of visual scenes, in contrast to humans, bees do not automatically encode predictability information in those scenes. Since access to predictability has long been considered as key for acquiring complex knowledge effectively, this difference might provide hints about what leads to human's versatile learning and superior cognitive abilities.

Scientists predict potential spread, habitat of invasive Asian giant hornet
Researchers at Washington State University have predicted how and where the Asian giant hornet, an invasive newcomer to the Pacific Northwest, popularly dubbed the ''murder hornet,'' could spread and find ideal habitat, both in the United States and globally. (2020-09-22)

Scientists "scent train" honeybees to boost sunflowers' seed production
If you want a dog to hunt something down, it helps to let them sniff an item to pick up the scent. Now, researchers reporting in Current Biology on September 17 have found that scent training honeybees might work in a similar way--and that this approach could make bees more efficient in pollinating crops. The findings show that honeybees given food scented with sunflower odors led to a significant increase in sunflower crop production. (2020-09-17)

Bumblebees benefit from faba bean cultivation
About one third of payments received by farmers are linked to 'greening measures' to promote biodiversity. These have been criticized because the benefits for biodiversity are unclear. Researchers, including Göttingen University, investigated whether the cultivation of faba beans (Vicia faba - broad bean or fava bean) can support wild bees. They found that bumblebees benefit from cultivating faba beans, while other wild bees depend on semi-natural habitats. Results are in the Journal of Applied Ecology. (2020-09-10)

Substances with anti-cancer action are identified in Brazilian red propolis
Researchers isolated eight novel polyphenols from the rarest type of propolis. Two of them were found to inhibit tumor cell proliferation in laboratory assays. (2020-09-09)

High human population density negative for pollinators
Population density, and not the proportion of green spaces, has the biggest impact on species richness of pollinators in residential areas. This is the result of a study from Lund University in Sweden of gardens and residential courtyards in and around Malmö, Sweden. (2020-08-25)

Out of sync: Ecologists report climate change affecting bee, plant life cycles
Reporting on the first community-wide assessment of 67 bee species of the Colorado Rockies, ecologists Michael Stemkovski of Utah State University and Rebecca Irwin of North Carolina State University say ''phenological mismatch,'' changing timing of life cycles between bees and flowers, caused by climate change, has the potential to disrupt a mutually beneficial relationship. (2020-08-19)

Research brief: Bee neighborly -- sharing bees helps more farmers
New paper shows the benefits of cost-sharing the conservation of wild bee habitats on agricultural lands, especially in nearby farming communities, can help overcome the tragedy of the commons. (2020-08-18)

Does city life make bumblebees larger?
Does urbanisation drive bumblebee evolution? A new study by Martin Luther University Halle-Wittenberg (MLU) and the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig provides an initial indication of this. According to the study, bumblebees are larger in cities and, therefore, more productive than their rural counterparts. In 'Evolutionary Applications', the research team reports that differences in body size maybe caused by the increasingly fragmented habitats in cities. (2020-08-17)

Decline in US bird biodiversity related to neonicotinoids, study shows
Bird biodiversity is rapidly declining in the US. The overall bird population decreased by 29% since 1970, while grassland birds declined by an alarming 53%. A new study from University of Illinois points to increased use of neonicotinoid insecticides as a major factor in the decline. (2020-08-14)

Palaeontology: 429-million-year-old eye provides a view of trilobite life
The internal structure of a 429-million-year-old fossilized trilobite eye is almost identical to that of modern bees, according to a study published in Scientific Reports. The findings suggest that the principles of vision in many insects and crustaceans today are at least half a billion years old. (2020-08-13)

Study shows inbreeding reduces cooperation in banded mongooses
Inbreeding can reduce cooperation in banded mongooses according to a recent study by researchers. (2020-08-11)

'Insect apocalypse' may not be happening in US
Scientists have been warning about an 'insect apocalypse' in recent years, noting sharp declines in specific areas -- particularly in Europe. A new study shows these warnings may have been exaggerated and are not representative of what's happening to insects on a larger scale. (2020-08-11)

Land-use change disrupts wild plant pollination on a global scale
Human changes to the environment have been linked to widespread pollinator declines. New research published in Nature Communications shows that intensive land use will further decrease pollination and reproductive success of wild plants, especially of those plants that are highly specialized in their pollination. (2020-08-10)

Air pollution impacts the health of wild pollinators
We have almost no idea how air pollution affects other organisms who breathe the same air as we do. In some of the first research in the world to try to address the physiological and molecular impacts of air pollution on our wild plants and animals, scientists from the Bangalore Life Science Cluster show that air pollution could be devastating for organisms we rely on most for our own survival - like the honey bee. (2020-08-10)

Decline of bees, other pollinators threatens US crop yields
Crop yields for apples, cherries and blueberries across the United States are being reduced by a lack of pollinators, according to Rutgers-led research, the most comprehensive study of its kind to date. Most of the world's crops depend on honeybees and wild bees for pollination, so declines in both managed and wild bee populations raise concerns about food security, notes the study in the journal Proceedings of the Royal Society B: Biological Sciences. (2020-07-28)

Study identifies spread of bee disease via flowers
One in 11 flowers carries disease-causing parasites known to contribute to bee declines, according to a Cornell University study that identifies how flowers act as hubs for transmitting diseases to bees and other pollinators. (2020-07-23)

Science sweetens native honey health claims
Examination of honey from five different stingless bee species across Neotropical and Indo-Australian regions has enabled for the first time the identification of the unusual disaccharide trehalulose as a major component representing between 13 and 44 g per 100 g of each of these honeys. The previously unrecognised abundance of trehalulose in stingless bee honeys is concrete evidence that supports some of the reported health attributes of this product. This is the first identification of trehalulose as a major component within a food commodity. (2020-07-22)

More flowers and pollinator diversity could help protect bees from parasites
Having more flowers and maintaining diverse bee communities could help reduce the spread of bee parasites, according to a new study. (2020-07-22)
