Prehistoric Response to Global Warming Informs Human Planning Today Since 2004, University at Buffalo anthropologist Ezra Zubrow has worked intensively with teams of scientists in the Arctic regions of St. James Bay, Quebec, northern Finland and Kamchatka to understand how humans living 4,000 to 6,000 years ago reacted to climate changes. |

Plant biologists fear for cress project Is enthusiasm withering for funding studies into Arabidopsis thaliana? The brilliant career of a diminutive weed may have hit a snag. Arabidopsis thaliana has been the darling of plant biologists for some 30 years because of its small genome and rapid growth, and in 2000 it became the first plant to have its genome sequenced. To capitalize on this, the US National Science Foundation (NSF) soon afterwards dedicated US$200 million towards determining the function of every Arabidopsis gene by 2010. |

38 % of World's Surface in Danger of Desertification Researchers have measured the degradation of the planet's soil using the Life Cycle Assessment (LCA), a scientific methodology that analyses the environmental impact of human activities, and which now for the first time includes indicators on desertification. The results show that 38 percent of the world is made up of arid regions at risk of desertification. Article in The International Journal of Life Cycle Assessment |

Idea of Restoring 'Natural Systems' Misses Mark as Response to Climate Change Challenges, Expert Argues The adage says that to discover the right solutions to a problem you first have to ask the right questions. As Arizona State University engineering professor Brad Allenby sees it, our search for technological solutions to large-scale environmental problems sometimes gets off on the wrong track largely because we're posing the wrong questions. |

Geraniums Could Help Control Devastating Japanese BeetleThe beetle, Popillia japonica Newman, can feast on a wide variety of plants, including ornamentals, soybean, maize, fruits and vegetables. But within 30 minutes of consuming geranium petals, the beetle rolls over on its back, its legs and antennae slowly twitch, and it remains paralyzed for several hours. The beetles typically recover within 24 hours when paralyzed under laboratory conditions, but they often succumb to death under field conditions after predators spot and devour the beetles while they are helpless. |

Asexual Plant Reproduction May Seed New Approach for Agriculture Farmers throughout the world spend an estimated $36 billion a year to buy seeds for crops, especially those with sought after traits such as hardiness and pest-resistance. They can't grow these seeds themselves because the very act of sexual reproduction erases many of those carefully selected traits. So year after year, farmers must purchase new supplies of specially-produced seeds |

Europe’s flora is becoming impoverished Halle/Saale. With increasing species richness, due to more plant introductions than extinctions, plant communities of many European regions are becoming more homogeneous. The same species are occurring more frequently, whereas rare species are becoming extinct. It is not only the biological communities that are becoming increasingly similar, but also the phylogenetic relations between regions. These processes have led to a loss of uniqueness among European floras, scientists from the DAISIE research project have published their findings in the current online edition of the scientific journal Proceedings of the National Academy of Sciences of the USA (PNAS). l'article PNAS |

Strategic Research Program Needed to Determine Whether, How Past Climate Influenced Human Evolution WASHINGTON -- Understanding how past climate may have influenced human evolution could be dramatically enhanced by an international cross-disciplinary research program to improve the sparse human fossil and incomplete climate records and examine the link between the two, says a new report from the National Research Council.

New Energy Source from the Common Pea: Scientists Create a Solar Energy Device from a Plant Protein StructureIf harnessing the unlimited solar power of the sun were easy, we wouldn't still have the greenhouse gas problem that results from the use of fossil fuel. And while solar energy systems work moderately well in hot desert climates, they are still inefficient and contribute only a small percentage of the general energy demand. A new solution may be coming from an unexpected source -- a source that may be on your dinner plate tonight. |

UE : l'autorisation de la culture d'une pomme de terre OGM est vivement critiquée La pomme de terre OGM Amflora de l'allemand BASF, dont la Commission européenne a autorisé hier la culture, suscite des critiques de la part des écologistes mais aussi du gouvernement français qui attend l'avis du HCB pour ''arrêter sa position''. Après l'annonce hier de la Commission européenne d'autoriser la culture de la pomme de terre OGM Amflora du groupe allemand BASF, les Ministères français du Développement durable et de l'Agriculture ont décidé le 2 mars de saisir le Haut Conseil des biotechnologies (HCB), ''notamment sur la présence, dans cette pomme de terre, d'un gène marqueur de résistance à un antibiotique'', ont-ils indiqué dans un communiqué commun. |
Stress and Trade-Offs Explain Life's Diversity: A New Model Plants and people alike face critical choices as they reproduce: to make a few big, well-provisioned seeds -- or babies--or many small, poorly-provisioned ones. Different species make strikingly different choices, resulting in a great diversity of life forms: Darwin's "endless forms most beautiful. |

Scientists Develop New Method for Tracking Seed Dispersal and Establishment A Penn State biologist and his collaborators have developed a new method for tracking seed movement and germination. According to Tomás Carlo, assistant professor of biology at Penn State and the leader of the study, the technique will be useful for studying plant dispersal and how plants adjust to global climate change. The technique also will enable scientists to gather biological information about invasive plants that is critical to controlling their spread. The team's results appeared in the December 2009 issue of the journal Ecology. |

Le cent-fautes de Claude Allègre Dans son dernier livre, L'Imposture climatique (Plon, 300 p., 19,90 €), un ouvrage d'entretiens avec le journaliste Dominique de Montvalon, le géochimiste et ancien ministre Claude Allègre formule des accusations d'une extrême gravité contre la communauté des sciences du climat. La cible principale de l'ouvrage est le GIEC, défini à tort par l'auteur comme le "Groupement international pour l'étude du climat" - il s'agit en réalité du Groupe d'experts intergouvernemental sur l'évolution du climat. |
La photosynthèse offre une nouvelle source d'énergie électrique Des chercheurs du CNRS ont transformé l'énergie chimique issue de la photosynthèse en énergie électrique. Ils proposent ainsi une nouvelle stratégie qui convertit l'énergie solaire en énergie électrique de manière écologique et renouvelable. Cette biopile pourrait aussi avoir des applications médicales. Ces travaux viennent d'être publiés dans la revue Analytical Chemistry. |

Forest Tree Species Diversity Depends on Individual Variation It's a paradox that's puzzled scientists for a half-century. Models clearly show that the coexistence of competing species depends on those species responding differently to the availability of resources. Then why do studies comparing competing tree species draw a blank? Competitors like black gums and red maples have coexisted for millennia in the shaded understories of eastern U.S. forests, yet species-level data offer scant proof that they respond differently to environmental fluctuations that limit access to light, soil moisture and other essential resources. |
More Frequent Fires Could Aid Ecosystems
With a changing climate there's a good chance that forest fires in the Pacific Northwest will become larger and more frequent -- and according to one expert speaking at a professional conference, that's just fine. |

DNA Sequencing Unlocks Evolutionary Origins, Relationships Among Flowering PlantsThe origins of flowering plants from peas to oak trees are now in clearer focus thanks to the efforts of University of Florida researchers. A study appearing in the Proceedings of the National Academy of Sciences unravels 100 million years of evolution through an extensive analysis of plant genomes. It targets one of the major moments in plant evolution, when the ancestors of most of the world's flowering plants split into two major groups |
