Groot alarm in de Verenigde Staten over de massale verdwijning van bijen. De daling van het aantal loopt op van 30 tot 60 procent in Californië. Bijen zijn essentieel voor de bestuiving van meer dan 90 fruitsoorten en groenten. Mobiele telefonie wordt als mogelijke oorzaak gezien. http://www.ravagedigitaal.org/2007nieuws/april/12/12.php | Handsfree is veiliger! | nokia - 16.04.2007 13:48
ik dacht dat ze met dansjes en geursignalen communiceren. Na ja, de beller is sneller (dood). Ook voor bijen. | sure.... | queen bee - 16.04.2007 17:50
so you place something with magnetic radiation in the middle of a bee hive, where bees are supposed to find their way based on polarization of the light as well as on magnetic fields - and the you are surprised that the bees don't find their way back... and then you link that to mobile phones be used else where? give me a break.... | oorzaak ccd? | hommeltje - 17.04.2007 10:42
Onder boeren in de VS wordt druk gediscussieerd over de mogeleijke oorzaken van de massale bijensterfte. Hier enkele bijdrages: Hi All, A knowledgeable area beekeeper was featured on yesterday's Vox Pop on the Albany, NY NPR station. And of course Colony Collapse Disorder (CCD) was a prime topic for both the presenter and the call-ins. The bottom line presented in the radio show is that it is definitely a major problem here in the northeastern US too, and there seem to be a number of factors that are contributing to the syndrome. Pesticides, which get brought back to infect the entire hive, have been taking a toll on bee health for some time. I remember seeing studies about this on the negative effects of Sevin, way back in the 1980's. There's been numerous additions to the toxic synthetics/chemical/hormonal pesticide arsenal since then, including increasing quantities GMO packets of living pesticides, tracers and antibiotic resistant gene packages as more area dairy farmers subscribe to growing Bt corn. Bee parasites have been around for a long time too, but lately gaining an upper hand as the bees tiny immune system is overwrought with toxic insults. We had a warm, wet fall here as well and that may be a factor except there was a prolonged wildflower season, too, with the wild asters. The winter finally came in cold, for sure, but that's nothing new for bees in this area and over the last decade winters have been decidedly warmer than usual in these parts, to the detriment of maple producers and the ski industry. CCD also seems to have affected beekeepers who fed their bees (both honey and fructose) and those who did not. In fact, there was mention of some abandoned hives full of honey that no other bees would even visit, indicating there might be contamination or toxins present. I have come across no tests or test results of this, however. While an overwrought cliche these days, the bees seem to be our latest canary-in-the-coal-mine. CCD is a serious widespread ecological phenomenon. As they say, one out of every three bites you take is thanks to honeybee pollinators...
