Subantarctic islands harbour a unique diversity of species, notably seabirds, and thus represent a key zone for biodiversity conservation. Along with interactions with fisheries, introduced species and pollution, infectious diseases are now acknowledged as a substantial threat to seabirds. Indeed, infectious diseases can cause massive mortality events, threatening population viability. For instance, Amsterdam Island (Southern … More Tracking predator and scavenger movements to understand pathogen spread among endangered seabirds
The Paris Agreement in 2015 recognized the necessity to drastically reduce greenhouse gaz emissions, in order to protect ecosystems and associated biodiversity at the global scale. Polar regions are extremely impacted by global warming, and the species adapted to these ecosystems are among the first threatened by environmental change. Many of these species, like the … More The future of emperor penguins is tightly linked to decrease of grenhouse gaz emissions.
The ZATA LTSER welcomes a new scientific programme, called “THEMISTO”, led by Cédric Cotte. The biodiversity of the Southern Ocean is still poorly known, whereas it is under growing threats related to climate change and overfishing. The shear size of this ocean as well as its weather conditions present a sizeable challenge to scientists, somehow … More THEMISTO: Toward Hydroacoustics and Ecology of Mid-trophic levels in Indian and SouThern Ocean
Among the consequences of climate change, the sea-ice coverage is changing fast. But is it increasing or decreasing ? Is the trend established on the long term, or are its dynamics more complex ? Is it changing at the same pace and in the same direction at both poles ? And above all, how will … More The change in sea ice dynamics, and the future of marine birds and mammals
