Towards a worldwide inventory of all plants

June 26, 2019

Declining biodiversity due to man-made habitat destruction and climate change means that information about plant diversity and its distribution across the planet is now crucial for biodiversity conservation. With the Global Inventory of Floras and Traits (GIFT), a team of researchers from the Department of Biodiversity, Macroecology and Biogeography at the University of Göttingen has taken an important step forward in documenting and understanding global plant diversity. The results appear in the Journal of Biogeography.

It is over 200 years since Alexander von Humboldt started investigating the striking differences in plant diversity, and for a long time research progress has been limited by data availability. In recent times, the sheer number of known species and complex multiple facets of biodiversity, such as species richness, functional plant characteristics and relatedness, has overwhelmed efforts to bring all this data together. The researchers had to collect and standardise huge amounts of information from hundreds of published checklists and numerous unpublished regional inventories. For the first time, GIFT collates information about the plant species composition in nearly 2,900 regions including islands and protected areas. The data already covers about 79 percent of the global land surface and includes 80 percent (over 315,000 species) of all plant species known to science. The GIFT database links plant species to their geographic distribution, structural characteristics and to modern reconstructions of their evolutionary relationships, as well as to geographic, climatic and socio-economic characteristics of the regions.

"GIFT allows researchers, for the first time, to analyse near complete patterns of global plant diversity and regional species composition along with past and present effects", says Head of Department, Professor Holger Kreft. "Given the recent warnings about the devastating impact of humans on nature, for instance by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), and an increasing public awareness about climate change and its consequences, the publication of GIFT is a vital contribution to the field," says Dr Patrick Weigelt, lead author. "We envision data from GIFT to serve as a baseline to assess changes in plant diversity due to climate change, habitat alteration or introduced invasive species from a local right up to a global scale."

#535 Superior
Apologies for the delay getting this week's episode out! A technical glitch slowed us down, but all is once again well. This week, we look at the often troubling intertwining of science and race: its long history, its ability to persist even during periods of disrepute, and the current forms it takes as it resurfaces, leveraging the internet and nationalism to buoy itself. We speak with Angela Saini, independent journalist and author of the new book "Superior: The Return of Race Science", about where race science went and how it's coming back.
