In a small population of endangered animals, says Stark, "any kind of reduction like that is going to be a problem." While the dunes may have harbored 25,000 Lange's metalmarks 50 to 100 years ago, damage to the dunes reduced the population to
The results clearly show that the most polluted sites had no, or only single wild bees, in artificial nests, whereas in unpolluted sites, the same nests contained 4 to 5 different species of wild bees, with up to ten individuals.
Canada's response to the "milk wars" in the United States in the 1970s was to establish a supply management system that both protects and restricts the income of its dairy farmers. A University of Illinois study examined how the government regulat
He says that marine macroalgae - common seaweed - can be grown more quickly than land-based crops and harvested as fuel without sacrificing usable land. It's a promising source of bioethanol that has remained virtually unexplored until now.
Food forests are shaping up to be the next evolution of urban farming. “A food forest is more of a perennial garden; it’s a land management system that’s based on the natural system of a forest,” said Glenn Herlihy. He designed the original plans for
he greatest threat at America’s borders, however, doesn’t come from smuggled penises. The greatest threat — at least in the food security sense of the word — is a nondescript brownish insect about the size of a lentil. It’s called the Khapra beetle (
The Roundup Ready era of biotechnology has reshaped agriculture's purchase of soybean seed and use of herbicides on row crops.
European earthworms are invading previously earthworm-free hardwood forests in North America the scientists say, and consuming the rich layer of leaf litter on the forest floor. In turn, herbaceous plants that thrive in thick leaf litter and provide
s. It turns out that the concentrated animal feeding operations (CAFO) model of raising cows on factory farms churns out milk with dangerously high levels of estrone sulfate, an estrogen compound linked to testicular, prostate, and breast cancers.
This allows the software to differentiate between root and water or organic elements in the soil much more effectively than previous techniques. The detailed accurate root architecture can then be seen in three dimensions
The rangeland plant had spread through the interior of British Columbia, ruining pastureland for cattle and impacting local economies.
Monsanto is attempting to counter-spin the poor PR its been deservedly receiving recently – by attacking US farmers who use its frankenstien agra products.
Worms can compost kitchen scraps and shredded paper much faster than the aerobic compost process utilized in most commercial backyard compost bins.
e research, led by the University of Bristol's School of Veterinary Sciences, found that spending early life in a complex farm environment increased the number of regulatory T-lymphocytes, the cells that damp down the immune system and limit immune
Monsanto made its decision public shortly before the British government’s final announcement on the prospects for GM food, and after research in Britain found GM farming would have long-term negative impacts.
The results of the research can now be used to produce new plant lines, such as crops which are economically valuable, which have an improved root system, making them better able to resist environmental changes which could lead to plant damage or p
Earlier studies have indicated that large-scale use of seaweed as an energy source could in theory supply the world's needs several times over and the UK government envisages between 560 and 4700 km sq of seaweed farms in its long-term energy
He decided to look at forests in Costa Rica and Trinidad because he already had colleagues there and they, like him, were intrigued by the fact that some tropical forests have dramatic nitrogen exports without apparent human causes.
Analyses of bees found dead in and around hives from several apiaries over two years in Indiana showed the presence of neonicotinoid insecticides, which are commonly used to coat corn and soybean seeds before planting. The research showed that those
Have you all heard about this? Yesterday I received a 2012 National Agricultural Classification Survey [from the USDA's National Agricultural Statistics Service] in the mail. They ask 25 nosey questions about how many of each animal we have on our
r. This is done using a heat exchanger, which receives heat from both the warm, polluted air that is being treated, and from the biochemical reactions taking place within the bi
A heap of dead bees was supposed to become food for a newly captured praying mantis. Instead, the pile ended up revealing a previously unrecognized suspect in colony collapse disorder—a mysterious condition that for several years has been causing dec
Raising seedlings irradiated with blue light has been shown to increase crop yield after planting because of the high accumulation of phenolic compounds.
First, the superweeds started turning Monsanto's Roundup Ready crops into a farmer's nightmare. Now, according to the US Environmental Protection Agency, Monsanto Bt corn that's genetically engineered to kill insects is losing its effectiveness again
A key chemical in that weapon – 2,4-D – is just months away from being dropped on agricultural land across the United States. Dow AgroSciences, which along with DuPont and Monsanto is heavily invested in genetically engineered crops, has petitioned t
China has enjoyed a huge wine-drinking boom in recent years and is now Bordeaux's largest export client. Analysts have predicted it will overtake the United States to become the largest wine-consuming nation within 20 years.
soils can be used to soak up carbon dioxide from the atmosphere, then they can generate carbon credits that can be sold to industrial polluters who want to offset their emissions.
But what was important was that the population density was as high as it had been when the area was being completely deforested. So you couldn’t say it was a Malthusian process. You had to say something had changed about the political ecology.
China is already doing plenty of things to the atmosphere above it, but most changes are byproducts of the country’s marathon industrial revolution. Now China plans to make some purposeful atmospheric changes
A farmer who relies primarily on animal power has to cultivate patience, Davidoff explains. "When you work with horses, you have to let go of the expectation that you're going to get everything done today." He works longer hours, but at a slower p
