Bees and other pollinating insects are just one factor in food production
http://feeds.sciencedaily.com —
No food for the human race without bees? It is not quite as straightforward as that. A case study by ecologists in a coffee-growing area in India reveals that pollinating insects are just one production factor among many. Farmers have several possibilities to increase their harvest.

Gene that helps honey bees find flowers (and get back home) discovered
http://feeds.sciencedaily.com —
Honey bees don't start out knowing how to find flowers or even how to get around outside the hive. Before they can forage, they must learn to navigate a changing landscape and orient themselves to the sun. In a new study, researchers report that a regulatory gene known to be involved in the detection of novelty in vertebrates also kicks into high gear in the brains of honey bees when they are lea

Hovering is a bother for bees: Fast flight is more stable
http://feeds.sciencedaily.com —
Bumblebees are much more unstable when they hover than when they fly fast, according to new research. Scientists used a mathematical model to analyze the way bumblebees fly at different speeds, showing that the bumblebee is unstable when it hovers and flies slowly, and becomes neutral or weakly stable at medium and high flight speeds.

New research confirms plight of bumble bees, persistence of other bees in Northeast
http://feeds.sciencedaily.com —
A new study shows that although certain bumble bees are at risk, other bee species in the northeastern United States persisted across a 140-year period despite expanding human populations and changing land use. The study informs conservation efforts aimed at protecting native bee species and the important pollinator services they provide.

Biologists compare new bees to 100-year-old records
http://feeds.sciencedaily.com —
Researchers have found that bees and plants have been surprisingly resilient in the face of warmer temperatures and changing land use. The forests that once grew 10 miles outside of Carlinville are fragments of what they were when Robertson, who collected specimens in the late 1800s, drove his horse and buggy. Fields of corn have replaced acres of trees and prairie. Natural areas have been conver
