Latest and Breaking Agriculture News

Alaska fish adjust to climate change by following the food
(NOAA Fisheries West Coast Region) Not all species may suffer from climate change. A new analysis shows that Dolly Varden, a species of char common in southeast Alaska, adjust their migrations so they can keep feasting on a key food source -- salmon eggs -- even as shifts in climate altered the timing of salmon spawning.

Securing future food supply for the developing world
(University of Erlangen-Nuremberg) An interdisciplinary research project led by FAU scientists aims to determine ways to increase the total biomass and starch yield of the cassava plant. The Bill & Melinda Gates Foundation, which combats disease, hunger and poverty in the developing world, has awarded $10 million in funding over a five-year period to the project, entitled 'Metabolic engineering of carbon pathways to enhance yield of root and tuber crops.'

New challenges for ocean acidification research
(Helmholtz Centre for Ocean Research Kiel (GEOMAR)) To continue its striking development, ocean acidification research needs to bridge between its diverging branches towards an integrated assessment. This is the conclusion drawn by Professor Ulf Riebesell from the Helmholtz Centre for Ocean Research Kiel and Dr. Jean-Pierre Gattuso from the French Centre National de la Recherche Scientifique and Universite Pierre et Marie Curie. In a commentary in the journal Nature Climate Change, the two internationally renowned experts reflect on the lessons learned from ocean acidification research and highlight future challenges.

A vegetarian carnivorous plant
(Oxford University Press) Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains.

Oil palm -- a modeled crop
(James Cook University) Australian scientists have developed a model for oil palm cultivation, aimed at helping growers of the crop maximize the yields of their plantations, while minimizing detrimental environmental impacts.

NASA/USGS satellite sees green-up along Colorado River's Delta after experimental flow
(NASA/Goddard Space Flight Center) A pulse of water released down the lower reaches of the Colorado River last spring resulted in more than a 40 percent increase in green vegetation where the water flowed, as seen by the Landsat 8 satellite.

Study finds Illinois is most critical hub in food distribution network
(University of Illinois College of Engineering) Illinois is the most critical hub in the network of US domestic food transfers, according to a new study at the University of Illinois at Urbana-Champaign. According to the report, the US food network moves more than 400 million tons of food annually. Of that total, more than 70 million tons are transported through Illinois, the most of any state in the nation.

550-million-year-old fossils provide new clues about fossil formation
(University of Missouri-Columbia) A new study from University of Missouri and Virginia Tech researchers is challenging accepted ideas about how ancient soft-bodied organisms become part of the fossil record. Findings suggest that bacteria involved in the decay of those organisms play an active role in how fossils are formed -- often in a matter of just a few tens to hundreds of years. Understanding the relationship between decay and fossilization will inform future study and help researchers interpret fossils in a new way.

How does enzymatic pretreatment affect the nanostructure and reaction space of lignocellulosic biomass?
(Mary Ann Liebert, Inc./Genetic Engineering News) Pretreatment of cellulosic biomass using cell wall degrading enzymes is a critical step in the release of sugars needed to produce biofuels and renewable, biobased chemicals and materials. A new study that demonstrates and quantifies the impact of enzymatic hydrolysis and drying on the nanostructure and available reaction volume of pretreated hardwoods and switchgrass is published in Industrial Biotechnology.

How will climate change transform agriculture?
(International Institute for Applied Systems Analysis) Climate change impacts will require major but very uncertain transformations of global agriculture systems by mid-century, according to new research from the International Institute for Applied Systems Analysis.
