Bina
STRÅLAS ihjäl!!!
Kalle Hellberg:
GSM-basarnas utsändning av frekvensen 1734 Hz t ex ligger mycket nära protonresonans-frekvensen i vatten i Jordens magnetfält.
Bin och vissa andra insekter, liksom
fåglar, navigerar bl a efter jordens magnetfält och påverkas totalt av de
elektromagnetiska strålningsfälten som människan producerar. De tappar navigationsförmågan och kan inte förmedla till varandra var nektarstinna växter finns, varvid pollinering uteblir. Bina har ”spejare” i sina samhällen som har till uppgift att leta reda på ”saftiga blomsterfält” och flyga hem till kupan och informera arbetsbina om dagens lämpliga ”arbetsplats”. Om denna viktiga funktion inte kan utföras för att bina är förvirrade, så blir det ingen hämtning till deras matförråd för vintern och hela bisamhällen dör ut och på sikt även allt annat levande.

A man-made electromagnetic environment?
One trend that also causes concern is the
electromagnetic environment. Ironically, power line pylons provide agricultral margins that are a haven for bees. In the US, it has been proposed that utilities do not mow the power line strips in order to halt the US decline in bees. Studies by Ulrich Warnke on bee behaviour in low frequency fields have, however shown supressed metabolic rates in bees, and a paper by J O Husing, ‘
Biene und Elektrizitat’ in Imkerfreund (Beekeeper Friend) in 1965 noted effects of low frequencies on bee behaviour patterns.
There has been a deal of research on other insects, some relating to dimensional aspects on insect antennae. T Jaski noted in 1960 (‘Radio waves and life’, Radio Electronics, 31. pp. 43), that orientational reactions were observed in large ants when exposed to a SHF field of 10,000 MHz. They oriented their antennas along this electric lines of force and lost their ability to communicate the location of food to others. It was noted that the antenna length of the ants used in these experiments was almost a quarter of the wavelength to which they were they were exposed.
High electric fields present a greater problem in conductive hives (Bidokas et al., 1988). But it may not be hives and electrical fields that add to bee problems, so much as magnetic fields. Bees have a magnetoreception system sensitive down to 26nT at 10 to 60Hz, according to Kirschvink et al. (1997), decreasing rapidly with increasing frequency. Maybe living under power lines isn’t a completely good idea. Balmori 2006, ‘Effects of the Electromagnetic Radiation emitted by Mobile Telephony on Insects; Ecosystems’ recounts the effect of mobile phone antennas on insects more generally.

"
Honey bees readily associate an odor with sucrose reinforcement, and the response generalizes to other odors as a function of structural similarity to the conditioned odor. Recent studies have shown that a portion of odor memory is consolidated in the antennal lobes (AL), where first-order synaptic processing of sensory information takes place. The AL and/or the sensory afferents that project into them show staining patterns for the enzyme nitric oxide synthase, which catalyzes the release of the gaseous transmitter nitric oxide (NO). The results show that pharmacological blockade of NO release impairs olfactory discrimination only when release is blocked before conditioning. Blockade of GABAergic transmission disrupts discrimination of similar but not dissimilar odorants, and does so when the block occurs before condition or before testing. These results show that GABA and NO regulate the specificity of associative olfactory memory in the AL."

Fåglarna minskar också väldigt mycket i antal (väldigt utsatta för mobilmaster):

Knappast att
bin och
fåglar bara inbillar sig...
