#Bees able to spot which flowers offer best rewards before landingbumblebees are able to connect differences in pollen quality with floral features like petal colour and so land only on the flowers that offer the best rewards according to a new
whilst foraging on flowers and so until now it has been unclear whether they are able to form associative relationships between
what a flower looks like and the quality of its pollen. The study used bumblebee foragers housed under controlled conditions to test
whether they do learn about flowers during pollen collection. Their results show that bumblebees can individually assess pollen samples
which may allow bees to quickly learn which flowers provide the most nutritious pollen rewards for rearing their young.
There is still very little known about how bees decide which flowers to visit for pollen collection.
Easily learning floral features based on pollen rewards without needing any nectar rewards is a fast and effective way to recognise those flower species
Bees need to be able to select flowers providing the most nutritious food for rearing their young.
which means they may be able to tell just from the colour of the petals which flowers are worth visiting.
when collecting nectar from flowers but since bees don't eat pollen when foraging we were interested to see
whether they could still learn which flowers to visit when collecting this resource. The experiments involved manipulating the quality of pollen offered to the bees by diluting the samples.
#For bees and flowers, tongue size matterswhen it comes to bee tongues length is proportional to the size of the bee
For bees and the flowers they pollinate a compatible tongue length is essential to a successful relationship.
Some bees and plants are matched very closely with bee tongue sized to the flower depth.
Other bee species are generalists flitting among flower species to drink nectar and collect pollen from a diverse variety of plants.
A bee collects pollen on its body as it laps sugar-rich nectar from within the cupped interior of the flower's petals
and carries the flower's genetic heritage away with it to fertilize the next flower of the same species that it visits.
Perched at the mouth of a flower the bee unfolds the beaky maxilla and extends its tongue into the corolla of the flower dipping
and retracting it to lap up the nectar. If its tongue is too short to reach the nectar the bee has a problem.
Long flowers like honeysuckle or columbine are too deep for short-tongued bees. But longer isn't always better;
long tongues are harder to wrangle into short flowers. Long-tongued bees are often specialists favoring a few deep-throated flower species. In the bumblebee-sparse southern tip of Argentina for example Bombus dahlbomii the native long-tongued giant of Patagonia has lost ground
to a new bumblebee from Europe the short-tongued generalist Bombus terrestris imported to help pollinate tomatoes.
Because specialists depend on just a few flowers they can be more vulnerable to change. Tongue length can

Exposure to this neonicotinoid pesticide seems to prevent bees from being able to learn these essential skills.
and returned to the colony how much pollen they collected and from which flowers. Bees from untreated colonies got better at collecting pollen as they learned to forage.
Besides collecting less pollen said Raine the flower preferences of neonicotinoid-exposed bees were different to those of foraging bees from untreated colonies.

#Flowers polarization patterns help bees find foodbees use their ability to'see'polarized light when foraging for food researchers based at the University of Bristol have discovered.
Polarization patterns occur on the petals of real flowers but are invisible to us and thus may be overlooked a hitherto component of floral signalling.
Around 53 per cent of flower species face downwards and thus their polarization patterns are presented in such a way as to be visually accessible to the region of the bee's eye
Light reflected from downward facing flowers also has the potential to contrast with skylight polarization patterns potentially helping the bee to detect
and identify such flowers. Professor Partridge said: Both pollinator and plant fitness is greatly dependent on the ability of pollinators to discriminate flowers accurately
and bees have been shown to be able to use a wide range of floral cues including colour shape texture certain chemical compounds
and temperature to improve the identification and recognition of flowers. Recent findings have added floral humidity and electric fields as additional methods with
which pollinators can discriminate flowers and it is advantageous for a plant to produce a number of different signals that a pollinator can utilise effectively.

so that they can later develop buds flowers and fruit during the growing season said biometeorologist and study lead author Dennis Baldocchi
while their preferred flowers respond less strongly and emerge later. Such a mismatch in timing could severely impact both bees and plants and the productivity of many agricultural crops.
Or bees may adapt by feeding on different plants that flower earlier. While this could be a positive sign that bees are adaptable it also may mean they are feeding on less nutritious plants

and are attracted to land on flowers popular with other bees when exposed to perilous situations according to new research from Queen Mary University of London.
The study published in the journal Proceedings of the Royal Society B shows that past experience of predation causes bumblebees to join other bees already safely feeding on flowers.
when bees find themselves in these predator-infested environments they locate safe places to eat by joining other bees that are already safely feeding on flowers.
when bees landed on a flower associated with danger foam pincers would trap the bee
This simulates an attack by a crab spider a predator that lurks on flowers to catch pollinators
In safe environments the bumblebees subsequently chose to feed from flowers at random but in dangerous environments the bees specifically flew to flowers that were occupied by other bees.
Erika added: It's similar to walking through a bad neighbourhood--you're more likely to choose a busier route where there are lots of other people around than a deserted street to get to your destination
Bees normally spread themselves out among flowers to minimise competition but when danger lurks they dine together to seek safety in numbers commented co-author Professor Lars Chittka from Queen Mary's School of Biological and Chemical sciences.

The paper published in the current issue of the Journal of Applied Ecology gives farmers of pollination-dependent crops tangible results to convert marginal acreage to fields of wildflowers said Rufus Isaacs MSU entomologist
As part of the study marginal lands surrounding productive blueberry fields were planted with a mix of 15 native perennial wildflowers.
Once the wild bees were more abundant more flowers turned into blueberries and the blueberries had more seeds
Based on the results a two-acre field planted with wildflowers adjacent to a 10-acre field of blueberries boosted yields by 10-20 percent.
which can recoup the money from planting wildflowers. With 420 species of wild bees in Michigan alone it makes sense to attract as many free pollinators as possible.
and northern Asia) and non-Palaearctic garden plants bees simply visited plants in proportion to flower availability. Indeed of the six most commonly visited garden plants only one--Foxglove--was a British native and only three of Palaearctic origin.
Among individual species however there were distinct preferences with the long-tongued'garden bumblebee'(Bombus hortorum) showing a strong preference for'native'Palaearctic-origin garden plants choosing them for 78%of its flower visits.

#As hubs for bees, pollinators, flowers may be crucial in disease transmissionlike a kindergarten or a busy airport where cold viruses and other germs circulate freely flowers are common gathering places where pollinators such as bees
and butterflies can pick up fungal bacterial or viral infections that might be as benign as the sniffles
But almost nothing is known regarding how pathogens of pollinators are transmitted at flowers postdoctoral researcher Scott Mcart
As major hubs of plant-animal interactions throughout the world flowers are ideal venues for the transmission of microbes among plants and animals.
Mcart adds Our intent with this paper is to stimulate interest in the fascinating yet poorly understood microbial world of flowers.
We found several generalities in how plant pathogens are transmitted at flowers yet the major take-home from our paper may be in pointing out that this is an important gap in our knowledge.
and where transmission must have occurred at flowers or pathogen-induced pseudoflowers. These are flower-like structures made by a pathogen that can look
and smell like a real flower for example. Regarding animal pathogens they identified 618 studies published before September 2013 using the same criteria.
In total we found eight major groups of animal pathogens that are transmitted potentially at flowers including a trypanosomatid fungi bacteria
and RNA VIRUSES they note. Their paper Arranging the bouquet of disease: Floral traits and the transmission of plant and animal pathogens was featured in the publisher's News Round up of most newsworthy research.
Traditionally research on flower evolution has focused largely on selection by pollinators but as Mcart and colleagues point out pollinators that also transmit pathogens may reduce the benefits to the plant of attracting them depending on the costs and benefits of pollination.

From the pollinator's perspective there has been surprisingly little work elucidating the role of flowers and floral traits for pathogen transmission.
