How can we tell if climate change really affects the population dynamics of a species? "Changes to behaviour, weight or appearance don't always mean population numbers are de- or increasing." NIOO-researcher Martijn van de Pol presents a novel approach to answering the question in the June issue of Ecology Letters.

The breeding grounds of Arctic migratory birds such as the barnacle goose are changing rapidly due to accelerated warming in the polar regions. They won't be able to keep up with these climatic changes unless they can somehow anticipate them. A team of researchers from the Netherlands Institute of Ecology (NIOO-KNAW) employed computer models to assess the prospects of the geese and their young. The results can be found in the scientific journal Global Change Biology.

55 trillion kilograms: that's how much carbon could be released into the atmosphere from the soil by mid-century if climate change isn't stopped. And all in the form of greenhouse gases such as CO2 and methane. Tom Crowther (NIOO-KNAW) and his team are publishing the results of a worldwide study into the effects of climate change on the soil in the issue of Nature that came out on 1 December.

Nearly 1000 'citizen scientists' sent in their observations this year on Soil Animal Days 2019. And a surprisingly high number of people tried to do something in return for the vital services these soil creatures provide for us.

‘If no action is taken to better understand and reduce the impact of climate change on insects, we will drastically limit our chances of a sustainable future with healthy ecosystems.’ This warning in a very topical paper in Ecological Monographs comes from 70 scientists from 19 countries around the world. But, they also provide ways to help insects in a warming world complete with management strategies.
