New paper showing latitudinal and elevational gradients in seed predation from an international collaboration

John and Dave participated in an international collaborative experiment testing whether biotic interactions are stronger at low compared to high latitudes. The experiment was conducted from the equator to the arctic and from low to high elevation at each latitude. It is the first coordinated experiment involving real organisms to test this idea dating back to Darwin. The results are published in Science Advances and are also described in a popular article and video.
