After much of Cape Breton’s oyster sector closed in 2002, Dr. Sarah Stewart-Clark, an assistant professor in the Department of Animal Science and Aquaculture in Dal’s Faculty of Agriculture, was determined to find a way to rebuild this 100-year-old economic and cultural activity.

The sector’s closure was the result of a pathogen found in oysters located in the Bras D’Ors Lakes. Known as the Haplosporidium nelsonii parasite (MSX), the disease causes high mortality in oyster populations but has no impact on humans.

Farmers in Montana, and other parts of the Northern Great Plains, are shifting from cereal mono-cropping to a cereal-dry pea cropping system. This transition is not without its share of unknowns, however.

Yield and performance of pea crops depend on both their genetics and the environment. Environmental factors such as temperature and rainfall can vary greatly. Farmers in different parts of the Plains need to know which varieties of pea will do well in the area they are farming.

There are many ways to make a living in a suitable climate but far fewer in a less suitable one. That may seem obvious for people living under various socio-economic stresses, but new research shows it also applies to the world’s plants – many of which are resorting to dramatic ‘last-stand’ strategies to survive in deteriorating environmental conditions.

The plant disease fire blight, caused by the bacterium Erwinia amylovora, is dreaded by fruit growers. It affects apple and pear trees and other plants in the rosacea family, and if a tree becomes affected it usually has to be cleared and burned.

A piece of research by the UPV/EHU-University of the Basque Country has concluded that designating Urdaibai as a protected area has improved the life quality of the citizens, despite placing certain restrictions on them.

In developing countries, more than three million children are at high risk for permanent blindness due to severe vitamin A deficiency.

Bali's famous rice terraces, when seen from above, look like colorful mosaics because some farmers plant synchronously, while others plant at different times. The resulting fractal patterns are rare for man-made systems and lead to optimal harvests without global planning. 

The next time you walk down the produce aisle of your grocery store, you may want to reach for red onions if you are looking to fight off cancer.

In the first study to examine how effective Ontario-grown onions are at killing cancer cells, U of G researchers have found that not all onions are created equal.

Making a living raising cattle isn’t as simple as just buying a herd and turning it out to pasture. Cattle require specific diets to maintain proper nutrition and weight gain. And how to do this in the most effective and efficient way possible has interested both ranchers and researchers for generations.

Winter is no time to flower, which is why so many plants have evolved the ability to wait for the snow to melt before investing precious resources in blooms.

Waking up to flower as the warmer, longer days of spring arrive — and the risk of a damaging frost recedes — requires a process called vernalization, in which flowering is blocked until the plant senses a sufficient cold spell. Researchers at the University of Wisconsin–Madison have identified a gene that keeps grasses from entering their flowering cycle until the season is right, a discovery that may help plant breeders and engineers get more from food and energy crops.
