Decline of Bees, Other Pollinators Threatens U.S. Crop Yields

Crop yields for apples, cherries and blueberries across the United States are being reduced by a lack of pollinators, according to Rutgers-led research, the most comprehensive study of its kind to date. Most of the world’s crops depend on honeybees and wild bees for pollination, so declines in both managed and wild bee populations raise concerns about food security, notes the study in the journal Proceedings of the Royal Society B: Biological Sciences.

Geoengineering’s Benefits Limited for Apple Crops in India

Geoengineering – spraying sulfur dioxide into the atmosphere to combat global warming – would only temporarily and partially benefit apple production in northern India, according to a Rutgers co-authored study. But abruptly ending geoengineering might lead to total crop failure faster than if geoengineering were not done, according to the study – believed to be the first of its kind – in the journal Climatic Change.

How to Tackle Climate Change, Food Security and Land Degradation

How can some of world’s biggest problems – climate change, food security and land degradation – be tackled simultaneously? Some lesser-known options, such as integrated water management and increasing the organic content of soil, have fewer trade-offs than many well-known options, such as planting trees, according to a Rutgers-led study in the journal Global Change Biology.

Mangrove Trees Won’t Survive Sea-Level Rise by 2050 if Emissions Aren’t Cut

Mangrove trees – valuable coastal ecosystems found in Florida and other warm climates – won’t survive sea-level rise by 2050 if greenhouse gas emissions aren’t reduced, according to a Rutgers co-authored study in the journal Science. Mangrove forests store large amounts of carbon, help protect coastlines and provide habitat for fish and other species. Using sediment data from the last 10,000 years, an international team led by Macquarie University in Australia estimated the chances of mangrove survival based on rates of sea-level rise.

Oyster Farming and Shorebirds Likely Can Coexist

Oyster farming as currently practiced along the Delaware Bayshore does not significantly impact four shorebirds, including the federally threatened red knot, which migrates thousands of miles from Chile annually, according to a Rutgers-led study. The findings, published in the journal Ecosphere, likely apply to other areas around the country including the West Coast and Gulf Coast, where oyster aquaculture is expanding, according to Rutgers experts who say the study can play a key role in identifying and resolving potential conflict between the oyster aquaculture industry and red knot conservation groups.

An Urbanized Florida Means More Stormwater Ponds, Invasive Plants

In their first attempt to quantify stormwater ponds, researchers with the UF Institute of Food and Agricultural Sciences found about 76,000 such ponds statewide. Many master-planned communities, especially in Florida, rely on stormwater ponds for flood control and water treatment. But the ponds also can be homes to many invasive plant species, which are costly to control.
