#Potential boost for worlds food supply: Resistance gene found against Ug99 wheat stem rust pathogenthe world's food supply got a little more plentiful thanks to a scientific breakthrough.
Eduard Akhunov associate professor of plant pathology at Kansas State university and his colleague Jorge Dubcovsky from the University of California-Davis led a research project that identified a gene that gives wheat plants resistance to one of the most deadly races of the wheat
and strategies that protect the world's food crops against the wheat stem rust pathogen that is spreading from Africa to the breadbaskets of Asia
A new study in ACS'Journal of Agricultural and Food Chemistry has found that the much-despised weed actually produces its own herbicides that kill nearby plants.
Animal behaviour is affected radically by the availability and amount of food. Studies prove that the willingness of many animals to take risks increases
However rotting fruit and plants--the flies'main sources of food--also release carbon dioxide. Neurobiologists in Martinsried have discovered now how the brain deals with this constant conflict in deciding between a hazardous substance and a potential food source taking advantage of the fly as a great genetic model organism for circuit neuroscience.
In various experiments the scientists presented the flies with environments containing carbon dioxide or a mix of carbon dioxide and the smell of food.
It emerged that hungry flies overcame their aversion to carbon dioxide significantly faster than fed flies
--if there was a smell of food in the environment at the same time. Facing the prospect of food hungry animals are
therefore significantly more willing to take risks than sated flies. But how does the brain manage to decide between these options?
#Uncertainty over the benefits of feeding birds in winterwild bird populations are thought generally to benefit from being given additional food in winter
but our understanding of the effects of such food provision is incomplete. The results of a new study carried out by researchers at the University of Exeter
The research published in Scientific Reports revealed that woodland blue tits that were provided with fat balls as a supplementary food during the winter months went on to produce chicks that were smaller of lower body weight and
which had lower survival than the chicks of birds that did not receive any additional food.
More research is needed to determine exactly what level of additional food provisioning and at what times of year would truly benefit wild bird populations.
As the wider scientific evidence shows feeding wild birds with appropriate foods delivers a range of positive benefits.
Whether providing food is detrimental or beneficial to wild bird populations it is clear that more research is needed to better understand its effects.

or did it win the competition for food? Or does the decline in herring gulls and the increase of lesser black-backed gulls maybe have nothing to do with each other?
From Camphuysen's research it appears that both gull species have benefited from an expanded food offering caused by people.
Herring gulls have learned to tap food in landfills while lesser black-backed gulls in particular were attracted by the fish waste that was put overboard at sea.
and the fishing fleets are shrinking both gull species are finding it more difficult to find food.
when there is barely enough food to be found for the hungry chicks. The fleet is expected to shrink even more in the coming years.
The problem of food shortage will continue to increase as a result but then not only at the weekend.
A strong inland increase of gulls looking for alternative food sources is one of the likely effects.
Camphuysen has equipped also gulls with a GPS data logger so as to be able to see where they look for food.
#Current global food production trajectory wont meet 2050 needscrop yields worldwide are not increasing quickly enough to support estimated global needs in 2050 according to a study published June 19 in the open access

Why Our Ancestor's Diets Matterthe earliest human ancestor to consume substantial amounts of grassy foods from dry more open savannas may signal a major and ecological and adaptive divergence from the last common ancestor we shared with African great apes
and 2. 5 million years ago contradicting previous claims that they ate forest foods. Later Theropithecus oswaldi ate a 75 percent grass diet by 2 million years ago and a 100 percent grass diet by 1 million years ago.

and water sustainabilityimprovements in crop water productivity--the amount of food produced per unit of water consumed--have the potential to improve both food security
and crop water productivity by climatic zone for 16 staple food crops: wheat maize rice barley rye millet sorghum soybean sunflower potato cassava sugarcane sugar beet oil palm rapeseed (canola) and groundnut (peanut.
The wide range of variation in crop water productivity in places that have similar climates means that there are lots of opportunities for improving the trade-off between food and water.
The researchers calculated that in drier regions bringing up the very lowest performers to just the 20th percentile could increase annual production on rain-fed cropland enough to provide food for an estimated 110 million people
and food insecurity says Brauman. For example if low crop water productivity in precipitation-limited regions were raised to the 20th percentile of water productivity specific to particular crops
and climates total rain-fed food production in Africa could be increased by more than 10 percent without exploiting additional cropland.

Failing such a change ultimately the EU will become almost entirely dependent on the outside world for food

We usually think of improving food crops solely in terms of traits such as the yield and quality of the food itself and apart from root crops such as potatoes and carrots these are easily visible aboveground traits.
However there is increasing recognition that the health and utility of plants can be enhanced greatly by improving belowground traits such as root growth.

First it is interlinked tightly with livestock production and the human food system. Second many people consider their pets to be part of the family so the food has to be culturally acceptable to the owner as well as good for the animal.
Finally pet food has to be affordable. As with human food dietary ingredient selection and nutrient composition affect the sustainability of the pet food system.
Protein is expensive both financially and environmentally so the choice of protein source and amount in the diet are particularly important.
Often they contain human-grade ingredients thus competing directly with the human food system which will have feed to a human population that is expected to reach 9 billion by 2050.
Nutritional sustainability is not just about minimizing environmental impact it also involves promoting pet health through appropriate nutrition and food quality and safety.
