Largest king penguin colony has shrunk nearly 90%
Largest king penguin colony has shrunk nearly 90%
The world's biggest colony of king penguins is found in the National Nature Reserve of the French Southern and Antarctic Lands (TAAF). Using high-resolution satellite images, researchers from the Chizé Centre for Biological Studies (CNRS / University of La Rochelle) 1 have detected a massive 88% reduction in the size of the penguin colony, located on Île aux Cochons, in the Îles Crozet archipelago.

The survival of sea birds affected by ocean cycles
The survival of sea birds affected by ocean cycles
In a general context of climate change, researchers at the Centre d'écologie fonctionnelle et évolutive (CNRS/Université de Montpellier/Université Paul Valery/EPHE-PSL) and their international partners revealed the impact of ocean cycles, such as the Pacific decadal oscillation and El Niño, on the survival of the Nazca booby, a species found on the Galapagos Islands.

Double trouble for a coral reef
Double trouble for a coral reef
Upolu, one of the nine islands of Samoa, in the Pacific Ocean. Well-known among fans of diving, this isolated coral reef promised to be a site of rich biodiversity for the scientists on the Tara Pacific expedition, principally from the CNRS, the CEA 1 and the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia.

A clearer understanding of the impact of extreme climate events on wheat yields
A clearer understanding of the impact of extreme climate events on wheat yields
France, the major bread-basket for Western Europe, experienced catastrophic yield losses in 2016. Scientists from INRA, CNRS and CEA 1 have shown that in 2016, and in other years, abnormally high temperatures in late autumn accentuated the negative effect on wheat production of excessive rainfall the next spring.

The dinosaur menu, as revealed by calcium
The dinosaur menu, as revealed by calcium
By studying calcium in fossil remains in deposits in Morocco and Niger, researchers have been able to reconstruct the food chains of the past, thus explaining how so many predators could coexist in the dinosaurs' time.

The great acceleration reaches new heights
An international team of researchers 1 , including a CNRS researcher at the department of Écologie et Dynamique des Systèmes Anthropisés (CNRS / Université de Picardie Jules Verne) has observed an acceleration in the increase of biodiversity on mountain peaks in Europe.

At a global scale, just 12 grape varieties (or 1% of cultivated varieties) occupy up to 80% of vineyards in some countries. Scientists from INRA and Harvard University in the USA have suggested that one of the levers that could be operated to adapt wine-growing to climate change is to exploit the diversity of other cultivated varieties by planting those that are less well known, and thus encouraging winegrowers and consumers to adopt new practices.

Tara Oceans : discovery of over 100 million genes from the marine world
Tara Oceans : discovery of over 100 million genes from the marine world
The Tara Oceans expedition (2009-2013) has enabled the collection of plankton samples in all of the world's oceans on board the schooner Tara , and the creation of catalogues of species and genes on a scale never before undertaken.

Installing rooftop vegetable gardens for sustainable cities
Installing rooftop vegetable gardens for sustainable cities
From producing food to regulating water runoff, urban agriculture has a lot to offer. Scientists from INRA and AgroParisTech have shown that rooftop vegetable gardens are an interesting way to recycle urban waste, produce food, and retain rainwater. Their The challenges of making today's cities more sustainable are legion: waste management, food supplies, sensitivity to heatwaves and the risk of flooding linked notably to the impermeabilisation of soils.

Gutters teem with inconspicuous life
Scientists from the BOREA Biology of Aquatic Organisms and Ecosystems research unit (CNRS / MNHN / IRD / UPMC / University of Caen / Université des Antilles)—together with a colleague from the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany—have shown that Parisian street gutters are oases of microscopic life, home to microalgae, fungi, sponges, and mollusks.

A new threat to pollination : the dark side of artificial light
A new threat to pollination : the dark side of artificial light
A European team, including a researcher from the Centre d'écologie et des Sciences de la Conservation (CNRS/MNHN/UPMC), has shown for the first time the direct and indirect impacts of artificial light on flower pollination. This threat to terrestrial ecosystems comes on top of other threats such as habitat loss, pesticide use, the spread of pathogens, and climate change.

Subtropical climate conditions and mangrove growth in Arctic Siberia during the early Eocene
Subtropical climate conditions and mangrove growth in Arctic Siberia during the early Eocene
Abstract The early Eocene (ca. 56'47.8 Ma) was an interval of exceptional warmth with reduced pole-to-equator temperature gradients. Climate proxies indicate mean annual air temperatures (MATs) and sea-surface temperatures (SSTs) exceeding 8'18 °C and frost-free, mild winters in polar areas, features that have proven difficult to reproduce with the most elaborate climate models.
