New paper: A first global assessment of remaining biodiversity intactness

Anthropogenic land use is one of the dominant drivers of ongoing biodiversity loss on a global scale and it has often been asked how much biodiversity loss is “too much” for sustaining ecosystem function. Our new paper in the journal Science came out last week and attempts to quantify for the first time the global biodiversity intactness within the planetary boundary framework. I am absolutely delighted to have contributed to this study and it received quite a bit of media attention so far ( https://www.altmetric.com/details/9708902 ) with a number of nice articles in the BBC and the Guardian.

In our study we calculated the Biodiversity intactness index (BII) first proposed by Scholes and Biggs (2005) for the entire world using the local biodiversity estimates from the PREDICTS project and combined them with the best available down-scaled land-use information to date. We find that many terrestrial biomes are already well beyond the proposed biodiversity planetary boundary (previously defined and set as a precautionary 10% reduction of biodiversity intactness). Unless these ongoing trends are decelerated and stopped in the near future it is likely that biodiversity loss might corroborate national and international biodiversity conservation targets, ecosystem functioning and long-term sustainable development.

Curlew is now on Twitter

Good news everyone (or bad). I have now officially joined Twitter. Never really understood the hype so far and I always believed that their website is just filled with cute cat gifs and pictures of peoples last dinner. However in the past month I increasingly caught myself reading a lot of interesting twitter discussions of some people. There is a lot of potential for collaborations and good advice similar to the Q&A websites, where I am already pretty active. So here I am. Will try to set it up properly later at home, tweet some news, follow some people. Social media doesn’t count as worktime (yet).


What Irony that this is actually my 5oth blog-post since I started this blog 🙂


Peer reviewed Videos

JoVE (Journal of visualized Experiments) just opened up a whole new section called Environment, which is potentially interesting for all ecologists and environmentalists. I really like the idea of peer reviewed videos in science and i am sure its gonna be the next frontier line. For instance, why read about a 3-4 pages long method paper on how to correctly sample insects in forests when you could just watch and listen so someone who demonstrates it?
