The Tea Bag Index: simple on the surface, complex beneath
Oftentimes the simplest scientific methods hide a whole iceberg of complexity. The Tea Bag Index (TBI) is no exception. On the face of it, it’s brilliantly straightforward: bury some green and rooibos Lipton tea bags, dig them up after about … Continue reading
The graph that surprises nobody
Our recent paper in Nature summarizing the work of the Dark Diversity Network contains a simple – and for that reason rather horrifying – graph. It’s not much more than a linear regression, a line through some points: It summarizes … Continue reading
Global impoverishment of natural vegetation revealed by ‘dark diversity’
Back in 2019, we ventured into the field with a rather unusual mission: to search for the biodiversity that wasn’t there. At first glance, this might seem counterintuitive – after all, we’re accustomed to documenting what exists. Yet, by exploring … Continue reading
Non-native plants in the worlds’ cities
Non-native species have been widely studied for decades, and their affinity with urban environments is no surprise to anyone in the field. However, just how many non-native species dwell in our cities was so far unknown. With a global consortium … Continue reading
Temporal changes along mountain roads
In 2012, during my master’s thesis, we began monitoring vegetation along three Norwegian mountain roads with a clear goal: to track how these plant communities would change over time. Time, of course, is a relative concept, and nature operates on … Continue reading
Fieldwork time!
It’s fieldwork time again! We have started to enjoy some cold, grey and dark days in the Dutch mud the last weeks, for our new project on the scale at which biodiversity varies (more on that here). Fieldwork in December, … Continue reading
