From the Arctic to the tropics: researchers present a unique database on Earth’s vegetation

Which plant species grow where, alongside which others - and why? In a new study, an international research team presents the world's first global vegetation database which contains over 1.1 million complete lists of plant species for all terrestrial ecosystems.

The greening of the earth is reaching its limit

A new study led by Josep Peñuelas and published in Nature Ecology and Evolution reveals that CO2 abundance in the atmosphere no longer has a powerful fertilizing effect on vegetation. The greening that has been observed in recent years is slowing and this will cause CO2 levels in the atmosphere to rise, thus increasing temperatures and leading to increasingly severe changes in climate.

Do drought-affected trees die of thirst or hunger?

A new study has concluded that, universally, trees that have died from drought are unable to transport water to their leaves. The findings also highlight trees that have drained their carbon reserves since they are not able to carry out photosynthesis. The results of the study will permit the creation of more precise models for predicting the effects of climatic changes on vegetation.
