Research News Brief

Research News Brief March 12, 2013:

A new study published in Ecology Letters analyzing 23 crops from 14 countries shows that diversified, organic farming boosts the abundance and diversity of pollinators. Animal-pollinated food products account for about one-third of the calories in the human diet, and upwards of 90 percent of some critical micronutrients, like vitamins A, C and E.

Berkeley-led consortium gets $3.4 million for transit research

Berkeley-led consortium gets $3.4 million for transit research March 5, 2013:

The University of California Transportation Center, a consortium led by UC Berkeley, has received a $3.4 million grant from the U.S. Department of Transportation for research into new multidisciplinary research in three key areas of interest surrounding transit development: environmental sustainability, economic competitiveness and livability.

Wild bees boost almond pollination by honey bees

Wild bees boost almond pollination by honey bees January 10, 2013:

Honeybees perform better when wild bees are around, at least when it comes to pollinating California almond crops, according to a new study co-authored by researchers at UC Davis and UC Berkeley. Native bees, such as bumblebees and carpenter bees, help increase the pollination efficiency of honey bees and the amount of fruit set. The findings illustrate the importance of pollinator diversity for the state’s $3 billion almond industry.

Less pavement, greater flower diversity lead to more bumblebee pollinators

Less pavement, greater flower diversity lead to more bumblebee pollinators December 24, 2012:

In a study of California bumbebees, former Berkeley post-doc Shalene Jha, now at the University of Texas, and Berkeley professor Claire Kremen found that populations decreased when more land was paved, but increased with floral diversity. This suggests that farmers should plant flowering hedgerows and cover crops to encourage native pollinators.
