Le patron de l’Agence de l’environnement américaine doute de l’impact du CO2 sur le réchauffement climatique
Dans une interview à la chaîne CNBC, Scott Pruitt, a également dénoncé le « mauvais accord » de Paris sur le climat.
Le nouveau patron de l’Agence de l’environnement américaine (EPA), le climatosceptique Scott Pruitt, a pris jeudi 9 mars le contre-pied du consensus scientifique mondial en estimant que les émissions de dioxyde de carbone (CO2) n’étaient pas un facteur déterminant dans le changement climatique, appelant à « continuer d’étudier l’analyse » de l’impact du CO2.

Don’t Wait for Ivanka Trump to Save the Climate
While we’re paying attention to Ivanka, the world is moving on without us.
The great director Alfred Hitchcock often spoke of the “MacGuffin,” a plot device that appears to move the story forward but merely leads to a dead end. (Some enjoy eating them as red herrings.) Ivanka Trump is our most dangerous MacGuffin in the climate arena?—?the MacGuffin dressed in pearls.

Proposed NOAA Budget Cuts Would Jeopardize Essential Tools
Experts say that cutting back on satellite programs is a bad idea.
... For the sake of comparison, the latest estimated cost for one F-35 fighter jet is about $102 million. Under Donald Trump, the defense budget would increase to $603 billion, more than 100 times as much as the entire NOAA budget?—?a slice so small that it doesn’t even show up on a federal budget pie chart.

La pollution sonore générée par le trafic routier affecte l’état sanitaire des animaux
Depuis le début des années 2000, de nombreuses études démontrent les conséquences de la pollution sonore générée par le trafic routier sur la biodiversité. Leur intérêt pour ce type de perturbation est assez récent, alors que l'on sait depuis longtemps que l'exposition sonore influence fortement la santé humaine et qu'en France la première loi relative à la lutte contre le bruit date du 31 décembre 1992.

European coastal regions at greatest risk from oil spills identified by new risk index
European Atlantic countries are, in general, at higher risk of being affected by oil spills than Mediterranean and Baltic countries, with the United Kingdom most affected, according to new research. The study developed a new risk index for analysing the potential vulnerability of coastal regions to oil spills at sea.

High soil carbon in Natura 2000 sites brings potential for climate-smart conservation
Natura 2000 sites have, on average, 10% more carbon in their topsoil than non-protected areas, according to new research. They also generally have lower economic value for agriculture. The results suggest that there is significant potential to develop win-win biodiversity conservation and climate change mitigation efforts within the EU.

Study shows acorn ants rapidly adjust, suggesting the insects may be able to cope with other sources of warming, including climate change
Urban acorn ants collected in Cleveland appear to have taken no more than 100 years -- no more than 20 generations -- to evolve and thrive in their heat-trapping city home. The capability suggests the species may be able to cope with other sources of rising temperatures.

Convergent con artists: How rove beetles keep evolving into army ant parasites
Marauding across the forest floor, aggressive army ant colonies harbor hidden enemies in their ranks -- parasitic beetles. Through dramatic changes in body shape, behavior, and pheromone chemistry, the beetles gain their hosts' acceptance, so they can feast on their brood. These beetles arose at least a dozen separate times from non-ant-like ancestors. This discovery provides evidence that evolution has the capacity to repeat itself in an astonishingly predictable way.

Redefining 'species'
New species concept based on mitochondrial, nuclear DNA coadaptation
What is a species? Biologists -- and ornithologists in particular -- have been debating the best definition for a very long time. A new commentary proposes a novel concept: that species can be defined based on the unique coadaptations between their two genomes, one in the nuclei of their cells and the other in their mitochondria.

During sampling of several Coffea arabica plantations in Tanzania severe root galling, caused by a root-knot nematode was observed. From pure cultures, morphology and morphometrics of juveniles and females matched perfectly with Meloidogyne africana, whereas morphology of the males matched identically with those of Meloidogyne decalineata. Based on their Cox1 sequence, however, the recovered juveniles, females and males were confirmed to belong to the same species, creating a taxonomic conundrum.

The planting of 162 ha of transgenic glyphosate-resistant creeping bentgrass (Agrostis stolonifera) near Madras, OR, USA, allowed a unique opportunity to study gene flow over time from a perennial outcrossing species at the landscape level. While conducting a four year in situ survey, we collected panicles and leaf tissue samples from creeping bentgrass and its sexually compatible species.

Pseudofrenelopsis and Brachyphyllum are two conifers that were part of the Lower Cretaceous (Aptian) taphoflora of the Crato Formation, Araripe Basin, northeastern Brazil. The former genus includes, so far, P. capillata and indeterminate species, whilst the latter is mainly represented by B. obesum, the most common plant megafossil recovered from that stratigraphic unit. Here, the stem and leaf anatomy of Pseudofrenelopsis sp. and B. obesum specimens is revisited, including the first report of some epidermal and vascular traits for both taxa from the Crato Formation.

Anthropocène ...
Ces étonnants cristaux qui n’existeraient pas sans l’homme
Petit à petit, l’idée que la Terre est entrée dans l’anthropocène fait son chemin parmi les chercheurs. L’anthropocène, ce serait une époque géologique dominée par les activités humaines. Par notre action sur l’environnement et notamment sur le climat, nous bouleversons en effet les couches supérieures de cet oignon qu’est notre planète : l’atmosphère, la surface de la Terre – que ce soit la biosphère, le sol, les océans, les glaciers et calottes glaciaires – et le sous-sol le plus immédiat.

La pollution sonore générée par le trafic routier affecte l’état sanitaire des animaux
Depuis le début des années 2000, de nombreuses études démontrent les conséquences de la pollution sonore générée par le trafic routier sur la biodiversité. Leur intérêt pour ce type de perturbation est assez récent, alors que l'on sait depuis longtemps que l'exposition sonore influence fortement la santé humaine et qu'en France la première loi relative à la lutte contre le bruit date du 31 décembre 1992.

European coastal regions at greatest risk from oil spills identified by new risk index
European Atlantic countries are, in general, at higher risk of being affected by oil spills than Mediterranean and Baltic countries, with the United Kingdom most affected, according to new research. The study developed a new risk index for analysing the potential vulnerability of coastal regions to oil spills at sea.

High soil carbon in Natura 2000 sites brings potential for climate-smart conservation
Natura 2000 sites have, on average, 10% more carbon in their topsoil than non-protected areas, according to new research. They also generally have lower economic value for agriculture. The results suggest that there is significant potential to develop win-win biodiversity conservation and climate change mitigation efforts within the EU.

Study shows acorn ants rapidly adjust, suggesting the insects may be able to cope with other sources of warming, including climate change
Urban acorn ants collected in Cleveland appear to have taken no more than 100 years -- no more than 20 generations -- to evolve and thrive in their heat-trapping city home. The capability suggests the species may be able to cope with other sources of rising temperatures.

Convergent con artists: How rove beetles keep evolving into army ant parasites
Marauding across the forest floor, aggressive army ant colonies harbor hidden enemies in their ranks -- parasitic beetles. Through dramatic changes in body shape, behavior, and pheromone chemistry, the beetles gain their hosts' acceptance, so they can feast on their brood. These beetles arose at least a dozen separate times from non-ant-like ancestors. This discovery provides evidence that evolution has the capacity to repeat itself in an astonishingly predictable way.
