Les éléments d’un drame humanitaire de grande ampleur sont réunis en Afrique de l’Est
Selon l’ONU, 20 millions de personnes ont aujourd’hui besoin d’une assistance alimentaire d’urgence dans sept pays.
Voilà des années qu’on n’avait pas vu revenir sa tête de gorgone émaciée. Elle a les traits de ces gosses au gros ventre et au corps squelettique. Il y a ces files d’attentes de malheureux en guenilles venus chercher une maigre ration alimentaire dans des camps de personnes déplacées.

On sait trop à quoi ressemble la famine en Afrique. Elle est là, de retour dans la partie est du continent noir. La mort rôde.

L’ONU, les organisations humanitaires préviennent : la faim pourrait tuer des dizaines de milliers de personnes dans les jours qui viennent.

Just who are these 300 'scientists' telling Trump to burn the climate?
... First of all, hardly anyone on the list was a climate scientist; many were not even natural scientists. It is almost as though anyone with a college degree (and there are about 21 million enrolled in higher education programs just in the USA) was qualified to sign that letter.

This paper presents the results of a consensus-driven process identifying 50 priority research questions for historical ecology obtained through crowdsourcing, literature reviews, and in-person workshopping.

A deliberative approach was designed to maximize discussion and debate with defined outcomes. Two in-person workshops (in Sweden and Canada) over the course of two years and online discussions were peer facilitated to define specific key questions for historical ecology from anthropological and archaeological perspectives.

Shell's 1991 warning: climate changing ‘at faster rate than at any time since end of ice age’
Critics say public information film shows Shell ‘understood the threat was dire, potentially existential for civilisation, more than a quarter of a century ago’
Climate change “at a rate faster than at any time since the end of the ice age – change too fast perhaps for life to adapt, without severe dislocation”. That was the startling warning issued by the oil giant Shell more than a quarter of a century ago.
The company’s farsighted 1991 film, titled Climate of Concern, set out with crystal clarity how the world was warming and that serious consequences could well result.

Pour une recherche et une médecine sexuellement différenciées (suite)
Sur les traces de l’épigénétique
Nous avons vu dans notre premier article que, dès la conception, avec une paire différente de chromosomes sexuels – XY pour le garçon et XX pour la fille – 30 % des gènes des hommes et des femmes s’expriment différemment dans tous leurs tissus. Ceci se traduit par de subtiles différences de base, de susceptibilité aux maladies mais aussi en réponse à divers environnements.
Notre génome est stable, définitif et identique dans chacune de nos cellules. Pourtant, il ne s’exprime pas de la même façon dans le foie, le rein ou le cerveau… Sans compter des différences selon le contexte physiopathologique, le sexe ou l’âge.

A l'échelle planétaire, leur propagation, en partie liée aux perturbations écologiques, impacte nettement l'espérance de vie.

Goal! Bees can learn ball skills from watching each other, study finds
In Science
Bees are better at problem solving than previously thought, and can learn tasks totally unlike their natural behaviour, say researchers
Bumblebees can learn how to manoeuvre a ball just by watching others carry out the task, researchers have discovered in the latest study to shed light on the insects’ surprising talents.
While bees have already been shown to be able to learn how to pull on strings, push caps and even rotate a lever to access food, researchers say the new study shows that bees are better at problem solving than we thought.

D'où viennent les fleurs ? L'« abominable mystère de Darwin » s'éclaircit
Le mystère de l'origine des plantes à fleurs est en partie levé grâce à une équipe du Laboratoire de physiologie cellulaire et végétale (CNRS/Inra/CEA/Université Grenoble Alpes), en collaboration avec le laboratoire Reproduction et développement des plantes (CNRS/ENS de Lyon/Inra/Université Claude Bernard Lyon 1) et les Jardins de Kew (Royaume-Uni). Leur découverte, publiée dans la revue New Phytologist, le 24 février 2017, nous éclaire sur une question ayant beaucoup intrigué Darwin : l'apparition d'une structure aussi complexe que la fleur au cours de l'évolution.

Wintering ducks connect isolated wetlands by dispersing plant seeds
Plant populations in wetland areas face increasing isolation as wetlands are globally under threat from habitat loss and fragmentation. Researchers show that the daily movement behavior of wintering mallards is highly predictable from the landscape they live in and that their daily flights contribute to maintaining the connections between wetland plant populations across increasingly fragmented landscapes.

Forest dynamics in the U.S. indicate disproportionate attrition in western forests, rural areas and public lands
Sheng Yang, Giorgos Mountrakis
Forests are experiencing significant changes; studying geographic patterns in forests is critical in understanding the impact of forest dynamics to biodiversity, soil erosion, water chemistry and climate. Few studies have examined forest geographic pattern changes other than fragmentation; however, other spatial processes of forest dynamics are of equal importance. Here, we study forest attrition, the complete removal of forest patches, that can result in complete habitat loss, severe decline of population sizes and species richness, and shifts of local and regional environmental conditions.

Invasive, native marsh grasses may provide similar benefits to protected wetlands
An invasive species of marsh grass that spreads, kudzu-like, throughout North American wetlands, may provide similar benefits to protected wetlands as native marsh grasses. According to new research, the invasive marsh grass's effects on carbon storage, erosion prevention and plant diversity in protected wetlands are neutral.

Density-dependent role of an invasive marsh grass, Phragmites australis, on ecosystem service provision
Seth J. Theuerkauf, Brandon J. Puckett, Kathrynlynn W. Theuerkauf, Ethan J. Theuerkauf, David B. Eggleston
Invasive species can positively, neutrally, or negatively affect the provision of ecosystem services. The direction and magnitude of this effect can be a function of the invaders’ density and the service(s) of interest. We assessed the density-dependent effect of an invasive marsh grass, Phragmites australis, on three ecosystem services (plant diversity and community structure, shoreline stabilization, and carbon storage) in two oligohaline marshes within the North Carolina Coastal Reserve and National Estuarine Research Reserve System (NCNERR), USA.

Riparian vegetation is a distinctive and ecologically important element of landscapes worldwide. However, the relative influence of the surrounding landscape on the conservation of the biodiversity of riparian remnants in human-modified tropical landscapes is poorly understood. We studied the surrounding landscape to evaluate its influence on leaf-litter-ant alpha and beta diversity in riparian remnants in the tropical montane cloud forest region of central Veracruz, Mexico

Our study shows that deep subseafloor sediments are populated by descendants of rare members of surface sediment microbial communities that become predominant during burial over thousands of years. We provide estimates of mutation rates and strength of purifying selection in a set of taxonomically diverse microbial populations in marine sediments and show that their genetic diversification is minimal during burial.
