Back the bees and friends: Big agriculture has the chance to help or hinder our most important pollinators, research argues

Posted by External 14 days ago General
https://www.sciencedaily.com — New research has identified future threats to, and opportunities for insects, birds, mammals, and reptiles that pollinate wild flowers and crops. 35% of global crop production, and 85% of wild flowering plants rely on hard-working pollinators to thrive. Researchers are therefore calling for proactive prevention not reactive mitigation, and continuation of positive steps to reduce chemical use acr Read More

Bees' ability to forage decreases as air pollution increases

Posted by External 48 days ago General
http://www.enn.com — Air pollutants interact with and break down plant-emitted scent molecules, which insect pollinators use to locate needed food, according to a team of researchers led by Penn State. The pollution-modified plant odors can confuse bees and, as a result, bees' foraging time increases and pollination efficiency decreases. This happens because the chemical interactions decrease both the scent molec Read More
