Potential economic and climatic impacts of windstorms in forests
Windstorms are extreme climatic events: rare occurrences with high environmental and economic costs. INRAE and AgroParisTech researchers used foresight modelling to simulate the effects of windstorms on French forests-important carbon sinks-and the French forestry industry through 2050. In one quarter of simulations, windstorms caused a 24% drop in carbon sequestration.

Planet 9, do you copy?
For nearly ten years, astronomers have been trying to demonstrate the existence of a massive object thought to be orbiting in the outer reaches of the Solar System. Although the hypothesis is widely debated, a recent study claims that the absence of such a body is statistically impossible. Now that Pluto is no longer considered a true planet, the Solar System counts just eight such bodies.

How humans transform island bird communities
It is known that people have been bringing alien bird species onto islands for thousands of years, but how this has shaped the diversity of those species has just been brought to light by a study soon to be published in the journal Ecology Letters. An international team of scientists led by three researchers from the CNRS and Paris-Saclay University 1 has shown that, on most of the 407 islands they considered, humans have a greater impact on alien species diversity than do geographic variables.

Modeling avian influenza in Asian poultry markets
A new study involving INRAE reveals the speed at which bird flu is spreading in live poultry markets in Asia. Scientists from the One Health Poultry Hub program have modeled the spread of avian flu in these markets, integrating for the first time biological data collected in the field. They focused their study on the H9N2 avian flu virus, which is not very virulent for poultry, but represents a major risk in the spread and evolution of the disease.

Emotion can also cause chickens to get red in the face
How can we know what chickens are feeling? An INRAE research team were able to uncover various degrees of redness on chickens' faces depending on their emotional state, while, at the same time, demonstrating that the skin of chickens that were used to humans stayed lighter in colour, thereby indicating a calmer state when humans were nearby.

The Earth, precariously balanced
Aerial view of slash-and-burn agriculture in the state of Amazonas, western Brazil (September 2022). On our planet, everything is interconnected, from terrestrial and marine ecosystems and biodiversity to ice sheets, rivers and oceans. But a recent report reveals that the dynamics of these different systems is being destabilised by human activities to such an extent that they are reaching points of no return.

Birds, collateral victims of agricultural intensification in Europe
The scientific community has been sounding the alarm over the effects of pesticide use on human health and the disappearance of numerous species in agricultural environments for half a century. As early as 1962, Rachel Carson's pioneering work predicted "silent springs" caused by the decline of birds, the collateral victims of pesticides via the poisoning of environments and the disappearance of insects.
