As Dalhousie’s Industry Chair in Wild Blueberry Physiology, David Percival had just one challenge: to put more berries in the box.

That was 20 years ago. Today, wild blueberry production in Nova Scotia has quadrupled to over 400 million pounds annually. And it’s a story that begins with Mr. Blueberry himself, John Bragg.

As global temperatures continue to rise, droughts are expected to become more frequent and severe in many regions during this century. A new study with NASA participation finds that land ecosystems took progressively longer to recover from droughts in the 20th century, and incomplete drought recovery may become the new normal in some areas, possibly leading to tree death and increased emissions of greenhouse gases.

In results published Aug. 10 in the journal Nature, a research team led by Christopher Schwalm of Woods Hole Research Center, Falmouth, Massachusetts, and including a scientist from NASA's Jet Propulsion Laboratory, Pasadena, California, measured recovery time following droughts in various regions of the world. They used projections from climate models verified by observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite and ground measurements. The researchers found that drought recovery was taking longer in all land areas. In two particularly vulnerable regions -- the tropics and northern high latitudes -- recovery took ever longer than in other regions.

If you live in the developed world, safe water is usually just a faucet-turn away. And yet, global warming, drought conditions, and population growth in coming decades could change that, ushering in an era of uncertain access to water.

Now an MIT-based research team has evaluated those potential problems and, based on a case study in Australia, suggested an alternate approach to water planning. In a new paper, the researchers find there is often a strong case for building relatively modest, incremental additions to water infrastructure in advanced countries, rather than expensive larger-scale projects that may be needed only rarely.

Simon Fraser University graduate student Oldooz Pooyanfar is monitoring what more than 20,000 honeybees housed in hives in a Cloverdale field are “saying” to each other—looking for clues about their health. 

Pooyanfar’s technology is gleaning communication details from sound within the hives with her beehive monitoring system—technology she developed at SFU. She says improving knowledge about hone

University of Lethbridge biogeography professor Dr. Dan Johnson and his team have been monitoring Prairie potato fields for the past few years, looking for evidence of the potato psyllid insect and a bacterium it can carry that can lead to zebra chip disease in potato crops.

“We found hundreds of potato psyllids last year, but we have found under 10 so far this year and none have the bacteria that cause zebra chip,” says Johnson, who coordinates the Canadian Potato Psyllid and Zebra Chip Monitoring Network.

With many Americans choosing to eat less meat in recent years, often to help reduce the environmental effect of meat production, UCLA geography professor Gregory Okin began to wonder how much feeding pets contributes to issues like climate change.

The health of dolphin populations worldwide depends on sustained access to robust food sources.

A new report by UC Santa Barbara researchers and colleagues at UC San Diego and the National Oceanic and Atmospheric Administration looks at three different dolphin species, studying what they eat and how they divide ocean resources and space -- important information for conservation and management. The team's findings appear in the journal PLOS ONE.

"We used the principle of 'you are what you eat' to unlock some of the secrets of dolphin diet," said lead author Hillary Young, an assistant professor in UCSB's Department of Ecology, Evolution, and Marine Biology (EEMB). "All of the foods that we or any animal eat are incorporated after digestion into body tissues. Most Americans, for example, chemically look like walking corn cobs because the foods we eat contain so much corn syrup."

The University of Twente and the German Research Centre Jülich are collaborating on developing membranes for an efficient separation of gasses, to use for the production of oxygen or hydrogen, for example.

The vulnerability of the European electricity sector to changes in water resources is set to worsen by 2030 as a consequence of climate change. This conclusion is reached by researchers at Leiden University in an article published in Nature Energy this month.

A University of Toronto startup that sells vertical hydroponic growing systems has joined forces with a Ryerson University-linked non-profit to bring down the stratospheric cost of fresh fruits and vegetables in Canada’s northernmost communities.

The unique partnership was forged at this year’s OCE innovation conference after Conner Tidd, a co-founder of U of T’s Just Vertical, ran into the founders of Ryerson’s Growing North. Tidd knew Growing North had built a geodesic greenhouse filled with hydroponic towers in Naujaat, NV.
