EU: 2014 could be the year we save the bees | SumOfUs.org

EU: 2014 could be the year we save the bees | SumOfUs.org | BeNews | Scoop.it

Bayer is suing Europe to overturn the landmark ban on bee-killing pesticides -- and we're excited to announce we're joining the legal battle to make sure Bayer fails.


Europe's bee-saving ban has only just gone into force, but Bayer is fighting in the courts to overturn it. If Bayer wins, it will be a huge setback for the bees -- and so we're asking the European Court of Justice to let us join in the case and defend the ban.


The first hearings could happen in just a few weeks, and we've only got a few days to finalize our case. If the court accepts our application, we'll represent the interests of hundreds of thousands of SumOfUs members who have already spoken up -- and make sure the court has real evidence to counter Bayer's propaganda. 


It's crucial we make our voices heard in the court and on the streets. We’ve already made a downpayment to hire European legal specialists to help us fight the case, but we know Bayer and Syngenta are going to throw everything they’ve got at defeating the bee-saving ban. That's why we need to stand ready to fight Bayer every step of the way -- no matter how long it takes.

Bees And Flowers Speak In A Secret UV Color Code

Bees And Flowers Speak In A Secret UV Color Code | BeNews | Scoop.it
Flowers may use UV patterns to attract bees. See how, and check out photos that shows us approximately what a bee sees when it looks at flowers.

 

UV fluorescence may be a common trait to most flowers, but might be of temporary occurrence for parts of the flower. Anthers, style, and pollen grains occasionally are seen to fluoresce. Strong fluorescence has been noted from nectar glands (Angelica sylvestris) and several other species. Some species show fluorescence of the non-fertilised stigmas, but this trait is difficult to document with my normal technical approach. Fluorescence from outside of the bracts is exhibited by some species. As far as the photography is concerned, the main issue with flower fluorescence is its transient behaviour. It may be present, but the flowers collected for photography don't appear to fluoresce simply because the floral development is in the "wrong" stage. With fluorescent pollen grains, their size often are at or below the detection limit unless quite high magnification is employed, thus calling for a true photomacropgraphic approach. The fluorescing pollen of Mirabilis jalapa has been documented using this method.

 

UV-absorbing substances (flavonyl glucosides) are instrumental in bringing about the fascinating pollinating guide patterns. UV marks on flowers are but a logical extension of the visual pollinating clues provided by evolution in nature. If the flower absorbs UV all over the floral parts, it may appear visually in a "UV-complementary" color even to pollinators capable of seeing in UV. We can only speculate as to the rendition of that complementary color, but if say the insect is modelled as seeing UV as "blue", blue as "green", and green as "red", then the UV complementary would be yellow. Thus, a UV-absorbing yellow flower still would come across as "yellow" even for an insect (or so it might seem, but who are we to know such things anyway).

Scientists discover what’s killing the bees and it’s worse than you thought | Quartz.com

Scientists discover what’s killing the bees and it’s worse than you thought | Quartz.com | BeNews | Scoop.it

As we’ve written before, the mysterious mass die-off of honey bees that pollinate $30 billion worth of crops in the US has so decimated America’s apis mellifera population that one bad winter could leave fields fallow. Now, a new study has pinpointed some of the probable causes of bee deaths and the rather scary results show that averting beemageddon will be much more difficult than previously thought.


Scientists had struggled to find the trigger for so-called Colony Collapse Disorder (CCD) that has wiped out an estimated 10 million beehives, worth $2 billion, over the past six years. Suspects have included pesticides, disease-bearing parasites and poor nutrition. But in a first-of-its-kind study published today in the journal PLOS ONE, scientists at the University of Maryland and the US Department of Agriculture have identified a witch’s brew of pesticides and fungicides contaminating pollen that bees collect to feed their hives. The findings break new ground on why large numbers of bees are dying though they do not identify the specific cause of CCD, where an entire beehive dies at once.


When researchers collected pollen from hives on the east coast pollinating cranberry, watermelon and other crops and fed it to healthy bees, those bees showed a significant decline in their ability to resist infection by a parasite called Nosema ceranae. The parasite has been implicated in Colony Collapse Disorder though scientists took pains to point out that their findings do not directly link the pesticides to CCD. The pollen was contaminated on average with nine different pesticides and fungicides though scientists discovered 21 agricultural chemicals in one sample. Scientists identified eight ag chemicals associated with increased risk of infection by the parasite.
