A new study argues that for fisheries policies to be effective they must take in to account not just fish stock conservation and environmental issues, but also research data on the patterns and dynamics of fish trade, markets and user consumption.
Agriculture in China predates domesticated rice: Discovery of ancient diet shatters conventional ideas of how agriculture emerged17 May 2013 | 7:57 am
Archaeologists have made a discovery in southern subtropical China which could revolutionize thinking about how ancient humans lived in the region. They have uncovered evidence for the first time that people living in Xincun 5,000 years ago may have practiced agriculture -- before the arrival of domesticated rice in the region.
Biologist Deborah M. Gordon's decades-long study of collective behavior in harvester ant colonies has provided a rare real-time look at natural selection at work.
Scientists have developed techniques for the genetic improvement of sunflowers using a non-GMO based approach. The new technology platform can harness the plant’s own genes to improve characteristics of sunflower, develop genetic traits, which will improve its role as an important oilseed crop.
Less oxygen means shorter time between molts, which means shorter life-span, which means fewer hungry grasshoppers. And for farmers, that’s very good news. A recent study offers insight into the relationship between respiratory function and molting that could help farmers save more of their crops.
A new study suggests that overgrazing and other factors increase the severity of cheatgrass invasion in sagebrush steppe, one of North America's most endangered ecosystems. Researchers said one of the most effective restoration approaches would be to minimize the cumulative impact of grazing, by better managing the timing, frequency of grazing and number of animals.
The gardener’s best friend, the earthworm, is great at protecting leaves from being chomped by slugs, suggests new research. Although they lurk in the soil, they seem to protect the plants above ground. Increasing plant diversity also decreases the amount of damage slugs do to individual plants.
The large-scale expansion of agriculture in the Amazon through deforestation will be a no-win scenario, according to a new study. The study shows that deforestation will not only reduce the capacity of the Amazon’s natural carbon sink, but will also inflict climate feedbacks that will decrease the productivity of pasture and soybeans.
A comprehensive five-year study by ecologists -- which included monitoring the activity of wolves, elks, cattle and humans -- indicates that two accepted principles of how ecosystems naturally operate could be overshadowed by the importance of human activity.
Bioenergy crops, such as Miscanthus and switchgrass, appear to be promising resources for renewable energy, but these new crops did not come with a manual on how to measure details on their sustainability impacts.
Prices received by farmers in March for grains, oilseeds, specialty crops, potatoes, cattle, hogs, poultry, eggs and dairy products are now available.
Data from the 2011 Survey of Functional Food and Natural Health Products are now available.
As of March 31, total stocks of most principal field crops were down compared with the same date in 2012. However, total stocks of corn for grain increased to record levels.
Data on stocks of frozen and chilled meats are now available for April.
Data on the production of eggs, placements of hatchery chicks and turkey poults, and stocks of frozen eggs and poultry meats as well as edible dried egg products are now available for February.
Data on major grain deliveries are now available for March.
Oilseed processors crushed 593 001 tonnes of canola in March. Oil production totaled 261 608 tonnes while meal production amounted to 354 313 tonnes.
Data on milled wheat and wheat flour produced are now available for February.
Planting intentions for 2013 show increases in spring wheat and durum wheat compared with 2012 as well as a possible decrease in canola acreage. Indications are that both corn for grain and soybean areas could reach new records nationally.
Sales of greenhouse, nursery and sod products in Canada were nearly $3.3 billion in 2012, a 2.2% decline from 2011. This reduction was partly the result of a 4.5% decrease in greenhouse vegetable and fruit sales, which accounted for one-third of all greenhouse, nursery and sod sales.
