Bees, Hornets, and Global "Warming"
"Hurt" wrote in message
oups.com... Could this be why bees are disappearing? Yesterday evening, while waiting for a bus, I noticed a bunch of bees dead on the pavement. I also noticed a hornet trying to carry away a dead bee body. Now I've seen this before so I figured that bees and hornets fight. And they do. Now I thought to myself, what if the missing bees are succumbing to a greater number or to the activity of hornets that is somehow related to global "warming". So I did a little "googling" and BINGO, a potential link. It turns out that hornets can be more active when exposed to more UV light because they stay cooler! So if greater solar activity is causing more UV light and warming, which I believe it is, it could also explain the missing bees. (See article) Any comments? http://groups.google.com/group/alt.conspiracy/topics http://physicsweb.org/articles/news/7/6/2/1 Insects stay cool with thermoelectricity 3 June 2003 Researchers in Israel have found the first evidence for natural heat pumps in living creatures. David Bergman and colleagues from Tel Aviv University used infrared imaging to show that wasps can sometimes remain much cooler than their surroundings. This is also the first time that the thermoelectric effect has been seen to play a role in the physiology of an animal (J S Ishay et al. 2003 Phys. Rev. Lett 90 218102). Some wasps and hornets live in parts of the world where local temperatures can reach 60 oC or more. 'Social' wasps live in nests and regularly go outside to forage for food. During such activities the wasp produces heat that originates in its flight muscles and then spreads throughout the rest of its body. This should make the wasps even hotter but in experiments with oriental hornets Bergman and co- workers found that the internal body temperature of the wasps could be significantly cooler than the ambient temperature. The Israeli workers argue that the insect must possess a heat pump, which works by using power generated from electrochemical reactions in its body. They believe that additional power is generated by the photovoltaic effect in the hornet's shell. This means that an electrical current is produced when the shell is exposed to sunlight - in a mechanism similar to that in a semiconductor p-n junction when irradiated with visible or ultraviolet light. "This could explain how hornets remain active even on very hot summer days," Bergman told PhysicsWeb. The researchers also took transmission and scanning electron micrographs of the shell. They observed a microstructure that was very similar to that of a practical thermoelectric heat pump - but on a different length scale (see figure). -----BEGIN PGP PUBLIC KEY BLOCK----- Version: PGPfreeware 5.0i for non-commercial use mQGiBEP19MQRBAD1RSIKvwYdk0l2MsOpAO0RH0DKyVOyCq0LL5 9yrIJaSmc1rBq +lXB08XIklLkgPEU6LmNBIDxJTnVuUuGLazYWxAzNm1eqXzV/7c6fZZo5FoGHfSBoHyL4Q/ glojLo3dUsP38I1uYRt4SwEOlh0pep59kUVz8zuVjQy6o3J0QI XQCg/y+90bSj0X5S8D/ 9UAqPh0x6FJ8D/20Yk0DWr/EM8NOn91b6ldm1pydv0KOZWOJjV7hBtlHtFG +xXMN4rCoarYhZwJufa8KCqL0iD3B1gYOpHvcfpUvI6fDGPIMK k5K4hj4XvvBV +Lz9xVSBbmzxCNvunBXJvtJ3mxfA5JBO5/48p/dPJGbrAg5pYU8VBXeNm13PLKDGA/ 473vE2+X4DnZmqDka +kd4AaMxHeMADSRUbldgUrvPsB6ibyabT4pSsOPzbUZhUTyl92 bv6+FgQct353DGnUqhTjgUYL7NJzHTiU3BO/ nZZ1CDi/ pudOO5VeCuEx5yEefzATZUaf1tmF7056ZcQHKlT3ONF6AMS2VK HEJvNTLaSRbQjSHVydCA8aHVydF9iZXlvbmRfcmVwYWlyQHlha G9vLmNvbT6JAEsEEBECAAsFAkP19MQECwMBAgAKCRAD8piUhVP PKtWxAJ9akLY9bmDIDd5qxiP4bRk9+q +Y3ACfVR+PCjZ5/iguRgxfEY8429zGhk65BA0EQ/ X0xRAQAPkYoH5aBmF6Q5CV3AVsh4bsYezNRR8O2OCjecbJ3HoL rOQ/ 40aUtjBKU9d8AhZIgLUV5SmZqZ8HdNP/46HFliBOmGW42A3uEF2rthccUdhQyiJXQym +lehWKzh4XAvb+ExN1eOqRsz7zhfoKp0UYeOEqU/ Rg4Soebbvj6dDRgjGzB13VyQ4SuLE8OiOE2eXTpITYfbb6yUOF/ 32mPfIfHmwch04dfv2wXPEgxEmK0Ngw+Po1gr9oSgmC66prrNl D6IAUwGgfNaroxIe +g8qzh90hE/K8xfzpEDp19J3tkItAjbBJstoXp18mAkKjX4t7eRdefXUkk +bGI78KqdLfDL2Qle3CH8IF3KiutapQvMF6PlTETlPtvFuuUs4 INoBp1ajFOmPQFXz0AfGy0OplK33TGSGSfgMg71l6RfUodNQ +PVZX9x2Uk89PY3bzpnhV5JZzf24rnRPxfx2vIPFRzBhznzJZv 8V +bv9kV7HAarTW56NoKVyOtQa8L9GAFgr5fSI/ VhOSdvNILSd5JEHNmszbDgNRR0PfIizHHxbLY7288kjwEPwpVs YjY67VYy4XTjTNP18F1dDox0YbN4zISy1Kv884bEpQBgRjXyEp wpy1obEAxnIByl6ypUM2Zafq9AKUJsCRtMIPWakXUGfnHy9iUs iGSa6q6Jew1XrPdYXAAICEADreGrD7qrpHqnIB7GU/ l62HAv1V13XW0/Zv/miVXNqeVMGY7kUpN/ NInWv7zUZZnhcdXfhSigCkWff1UBsrm5K4Ln0qzjIsmg6QQVWK UZiQvgwszOPCOp8T23AtQ1lyFBs/ Z9N6/ S0N7UEXvYZqGpBBBX9GLszgjeR00w96K6dpotRkIsLgBeQBhjI 2LXcmXdNZf1o3C5ERslm7NKYb5wjloV9eGsJsfMlqma/ 6i61/adhGzLevSWqGSLqCenqI/Z9LRLnHTpOj/8hgFI1RaqkCbtZukqcGzYThzU +iW5qrkZykT+tL5dqVEwTsHbRhe86Yi/RnHwCa9we +0+cSF52bKxqS1Efi7UnuUm7TAYj50YSWgdy08Too6XrEXaSPQ sxmxZ/yx+O +gY6bP1eWyJWWRwkQzJcxa0t+BD/06yl5gotT9kTU3JTCSRjJ5649zW+/ iwI4DwDBMrL2ajl4c1WEFZxxrcO7ULEHQD9cwXmtXyd2r568fR pBWOu6KN7wscHb/ +uM46rokKZEuq2Ruk9T0kL4Vos92PFIAd5UrhyvUGunHk7DLHO gf4tSjnChg6ewNdTvy1w/ lNLvCPag/1WRoC3Ak61d5Sp3Ib77JqbasVOcYAsLGVWeUGAP +CU1asRtIPCmJpT2Ay1m6Kte89+sGB8BzUlJOxwlUXmVFmWMYk APwMFGEP19MUD8piUhVPPKhECiGoAoJ1ZG0W6wWzooBcqshdcm TIzhO3oAJ4/ vFLy8IjcTkJzxZm8Jgm/krZXnQ== =BXko -----END PGP PUBLIC KEY BLOCK----- No. The reason for the decline is a mistake of the corporate farming groups in their attempt to block local gardening. IE corner the food market. They suffer the same results. -- Dave |
