    Vrlo korektno, lijepo i razumljivo opisano.

    Uzgred, iako se ne interesovah nešto na polju specifičnosti pčela, što ih više upoznajem NA OVAJ NAČIN uviđam da su fascinantna živa stvorenja! možda i najfascinantnija za koja znam! Ovaj mi se link učinio podosta pristojnim na temu ishrane pčela http://www.pcelarstvo.hr/index.php/radionica/373-prehrana-pcela#

    Mada, iako populistički - rekli bi mnogi; Zabrinjavajuć je i broj stranica koje rezultira ovakva pretraga → http://lmgtfy.com/?q=bee+gmo

    Ne znam, s jedne strane čujem da ih je sve manje, s druge da se sve više ljudi bavi pčelarstvom, s treće kad pogledam rafove s medom od Saut Kerolajne preko Pg do Šangaja.... nejasno mi je kako ih toliko ima, il se med pravi u fabrikama! S obzirom da je na ovim našim prostorima od prošlogodišnje tone meda ova godina spala na 400-500kg.

    Kod nas pčelari svake godine kukaju kako je gora od one prošle a niko ne bataljuje taj posa. Ove godine nije bilo suše pa mi je nešto za očekivat da je i paša bila dobra a nisu imali potrebu iznosit košnice u planinu.
    Ubi me ovaj bolji život!

    Jos jedan update: http://www.the-scientist.com/?articl...--Misleading-/

    Statisticians debunk a 2013 study by scientists at a Swiss agrochemical company, which had reported that a neonicotinoid pesticide posed a low risk to honeybees.

    Scientists are scrambling to protect honeybees and bumblebees as climate change, disease, and pesticides chip away at their fragile populations. Several studies have implicated neonictinoid pesticides in the deaths of honeybees and other pollinators. But proponents of these compounds point to a 2013 PLOS ONE study by researchers at the Swiss agrochemical company Syngenta, which reported that neonictinoida pose low risk to bee populations. But now, as described in a study published January 23 in Environmental Sciences Europe, another group has analyzed the statistical methods behind the Syngenta-led study, finding them wanting. “The estimates of the treatment effects were so imprecise that one could not tell whether the effects were either too small to pose a problem or, in contrast, so large as to be of serious concern,” coauthor Jeremy Greenwood of the University of St Andrews in Scotland said in a statement. “The experiments were on such a small scale that little useful could be concluded from them.”

    The statistical re-analysis comes on the heels of revelations that Syngenta had been hiding unpublished research—obtained by Greenpeace through the US Freedom of Information Act—indicating that high doses of the company’s pesticides can harm bee colonies, The Guardian reported.

    In this latest study, Greenwood and colleagues at demonstrated that the 2013 study lacked statistical power. Specifically, the St Andrews–based team noted that the Syngenta group did not conduct formal statistical analyses on their data, because they felt that “would be potentially misleading,” as the authors wrote in PLOS. But, as the St Andrews team noted, formal statistical analyses are only potentially misleading, whereas avoiding them entirely is entirely subjective.
    Greenwood and colleagues concluded that, without proper statistical analyses, the 2013 study is little more than an opinion piece. “Conclusions derived from inspection of the data were not just misleading in this case but are unacceptable in principle,” the St Andrews team wrote in Environmental Sciences Europe. “Any conclusions reached from such informal approaches can do little more than reflect the prior beliefs of those involved.”

    Svasta od ovog kretena: http://www.the-scientist.com/?articl...gered-in-U-S-/

    Update (February 13): Regulations to protect the rusty patched bumblebee were supposed to go into effect last week. But, as the Associated Press reported on February 10, these conservation efforts will not begin as scheduled because of an executive order issued by President Donald Trump, restricting new regulations.

    Jos jedan pozitivan update ovog puta od EU: https://www.theguardian.com/environm...ing-pesticides

    EU agrees total ban on bee-harming pesticides

    The world’s most widely used insecticides will be banned from all fields within six months, to protect both wild and honeybees that are vital to crop pollination

    Obican covek ovde ne moze mnogo sta da se pita i moze samo da se nada da ce oni na pozicijama voditi odgovornu politiku kada se radi o ovakvim stvarima. Sto je slaba uteha ali posto je citav region u obavezi da sve vise uskladjuje svoje propise sa onima u EU mozda ce barem oni po tom pitanju biti mudriji (kada vec nisu oko nekih drugih stvari ali da se ne zalazi sada u neke druge teme) i znati da na pravi nacin sto vise suzbiju ovaj problem. Ima jos dosta ovakvih apokalipticnih scenarija, narocito onaj u vezi sa nestasicom pijace vode i uopste buducnost je toliko neizvesna i moze itekako biti vrlo sumorna. I sadasnjost je takva da je u mnogim drzavama ljudski zivot jako jeftin i pojedinac se gleda samo kao potrosna roba.

    Pcelu bas nebih ubio posto sam svjestan ovog globalnog problema i njihovog znacaja. Zivim u Podgorici ali gdje god da jedem napolju u gradu ili cak unutar objekta ako su otvorena vrata pojave se. Cak i na selo ne mozemo jes na terasi s mirom a da se ne pojave.

    Citam da one imaju najveci znacaj u kontroli populacije insekata stetocina, a sto se tice oprasivanja evo sad tek saznah da i one to rade tako da cu se sledeci put def. naoruzat strpljenjem

    Monsanto, naravno: https://www.theguardian.com/environm...research-finds

    Tu kompaniju treba zapalit sa sve zaposlenima.

    Gledao sam nedje na TV da imaju neku smjesu koju pomijesaju sa stvarnim medom i dobiju tipa do 30% uvecanja u kolicini, a kvalitet (naravno gori) jos uvijek prolazi sve to norme koje su propisane.
