There is much wrong with the taxonomy of the plant genus Phyllanthus. Roderick Bouman of the Hortus botanicus Leiden has developed a new phylogeny for Phyllanthus and exposes the evolution of the plant genus. Publication in TAXON.

Large-scale forest fires started by prehistoric hunter-gatherers are probably the reason why Europe is not more densely forested. This is the finding of an international team, including climate researcher Professor Jed Kaplan of the University of Lausanne and archaeologist Professor Jan Kolen of Leiden…

On Wednesday 4 September, Queen Máxima opened the renovated tropical greenhouse complex of the Leiden Hortus Botanicus, an event that attracted wide public interest. Thanks to this renovation, the greenhouses are even better equipped for scientific research.

I think we should go this way. This way! THIS! WAY!! Making yourself heard in a city can be difficult. That is not only the case for humans, but birds seem to be hindered by urban noise as well. Researcher Hans Slabbekoorn of Leiden University already showed that great tits in Leiden communicate differently…

Smallholder farms in tropical regions can double their crop production by 2030 compared to 2015, a study finds to which José Mogollón (Institute of Environmental Sciences) contributed. But to achieve this, the farmers must increase the input of phosphorus beyond what is currently foreseen. The study…

This study focuses on the local level impacts of a highly globalised industry: the international trade in tropical timber.

Recently a Memorandum of Understanding (MOU) was signed between the Institute of Environmental Sciences (CML) - Leiden University and the Mulawarman university in Samarinda, Kalimatan province, Indonesia. The MOU will be effective for a period of five years and covers the intention to collaborate in…

Plants are vital resources throughout human history, but we know little about how they were used and valued prior to agriculture. Sandrine Gallois, an ethnoecologist working in the ERC-funded HARVEST project, has developed an interdisciplinary approach, combining anthropology and botany to explore how…

Which plant species grow where - and why? In a new study in Nature Ecology & Evolution, 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.

Historical figures such as Columbus have returned to the centre of public debate. Much remains to be discovered about his legacy and current impact on our society. A new study shows the ecological footprint that the arrival of Europeans left in the Caribbean islands.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

The strange tropical plants belonging to the Corsiaceae family first emerged millions of years ago on the supercontinent of Gondwana. That is what Leiden University researcher Constantijn Mennes concludes in an article in the Journal of Biogeography.
