when they land on flowers, this charge helps pollen to stick to their hairs. Daniel Robert, a biologist at the University of Bristol, UK, knew that such electrical interactions would temporarily change the electrical status of the flowers
but he did not know whether bumblebees were picking up on this. Keen to find out, he and a team of colleagues measured the net charges of individuals of Bombus terrestris, a common species of bumblebee,
and measured the flowers'electrical potentials. Sure enough, when the bees landed, the flowers became a little more positively charged.
Finally, the team released bumblebees into an arena with artificial flowers, half of which were carried positively charged and a sucrose reward,
Over time, the bees increasingly visited the rewarding charged flowers. But when the researchers turned off the electrical charge on the flowers
and re-released the trained bees, the insects visited rewarding flowers only about half of the time,
as they would have by random chance. That suggested that the bees were detecting the electric fields

fewer flowers received their own type of pollen. As a result, each flower produced one-third fewer seeds on average."

#The origin of flowers: DNA of storied plant provides insight into the evolution of flowering plantsthe newly sequenced genome of the Amborella plant addresses Darwin's abominable mystery--the question of why flowers suddenly proliferated On earth millions of years ago.
The genome sequence sheds new light on a major event in the history of life On earth: the origin of flowering plants including all major food crop species. On 20 december 2013 a paper by the Amborella Genome Sequencing Project that includes a full description of the analyses performed by the project as well as implications for flowering plant research will be published in the journal Science.
In the same way that the genome sequence of the platypus--a survivor of an ancient lineage--can help us study the evolution of all mammals the genome sequence of Amborella can help us learn about the evolution of all flowers said Victor Albert of the University
and many are known to be important for producing the flower as well as other structures and other processes specific to flowering plants.

and RMIT University have investigated the evolution of flower colors due to the bee's color vision.
Associate professor Adrian Dyer of Monash and RMIT said previous studies had shown that flower color evolved to attract bees as pollinators in temperate environments
Using computer models to examine flower colors as bees would see them the team addressed how pollinator vision had shaped flower evolution.
Dr Shrestha said flowers from both subtropical (900-2000m) and alpine (3000-4100m) regions showed evidence of having evolved color spectral signatures to enhance discrimination by bee pollinators.
The research could shed light on how flower colors may continue to evolve in particular environments depending upon the availability of the most effective pollinators.

#Flower research shows gardens can be a feast for the eyes #and the beesare our favourite garden flowers attractive to hungry visitors such as bees and butterflies to feed on?
Researchers at the Laboratory of Apiculture and Social Insects (LASI) at the University of Sussex have completed one of the first scientific studies to put the business of recommending pollinator-friendly garden flowers on a firmer scientific footing.
The study s findings are published today (17 october 2013) in the journalfunctional Ecology. Gardens are more important than ever as a source of food for a wide variety of insects who feed on the nectar
and pollen found in many flowers: pollinators such as bees and butterflies are in decline globally with one of the main causes being the loss of flowers especially in the countryside.
As popular support for wildlife continues to grow gardeners are increasingly looking for ways to help bees
and other insects by providing attractive flowers in their gardens for insects to feed on. To do this they often rely on#oepollinator-friendly#plant lists.
The study funded by the Body shop Foundation involved repeatedly counting flower-visiting insects over two summers as they foraged on 32 popular summer-flowering garden plant varieties in a specially planted experimental garden on the University s
and had to flower mainly or exclusively in July/August. 2one key result found by researchers Professor Francis Ratnieks
and his Phd student Mihail Gaburzov was that garden flowers attractive to the human eye vary enormously (approx 100-fold) in their attractiveness to insects meaning that the best plants for bees
But our study clearly shows that planting pollinator-friendly flowers is a no-cost win-win solution to help the bees.
Flowers that attract bees are just as easy to grow and just as pretty and cost no more.
Plant the right flowers and the bees will come.##Mihail Garbuzov says:##oewe basically counted bees
and other insects visiting flowers in bloom to determine the most attractive. Anyone can do this in their own garden or park or even when shopping for plants in a garden centre.#

The fleshy part of the fruit we eat is actually a modification of the shoot tip from which the flowers developed.
This intervention led to the appearance of red stigmas in the flowers and the production of anthocyanins in immature fruits.

#Fear of predators drives honey bees away from good food sourcesmost of us think of honey bees as having a bucolic pastoral existence--flying from flower to flower to collect the nectar they then turn into honey.
and wait to ambush them on flowers. Such fear drives bees to avoid food sources closely associated with predators
and therefore fossilize more easily than leaves and flowers. An uninterrupted sequence of fossilized pollen from flowers begins in the Early Cretaceous approximately 140 million years ago
and it is assumed generally that flowering plants first evolved around that time. But the present study documents flowering plant-like pollen that is 100 million years older implying that flowering plants may have originated in the Early Triassic (between 252 to 247 million years ago) or even earlier.
That is why the present finding of flower-like pollen from the Triassic is significant says Prof.

#Bees betray their flowers when pollinator species declineremove even one bumblebee species from an ecosystem and the impact is swift and clear:
The study to be published by the Proceedings of the National Academy of Sciences focused on the interactions between bumblebees and larkspur wildflowers in Colorado's Rocky mountains.
We found that these wildflowers produce one-third fewer seeds in the absence of just one bumblebee species says Emory University ecologist Berry Brosi who led the study.
The experiments focused on the interactions of the insects with larkspurs dark-purple wildflowers that are visited by 10 of the of the 11 bumblebee species there.
The researchers studied a series of 20-meter square wildflower plots evaluating each one in both a control state left in its natural condition
while in other cases they could follow the bees to 100 or more flowers. Running around after bumblebees in these beautiful wildflower meadows was one of the most fun parts of the research Brosi says.
Much of this bee team was made up of Emory undergraduate students funded by the college's Scholarly Inquiry
. While about 78 percent of the bumblebees in the control groups were faithful to a single species of flower only 66 percent of the bumblebees in the manipulated groups showed such floral fidelity.
