Open archives day - one of my favourite stories from last year has just been switched to open access. It's about how large animals move nutrients against the hydrological cycle, including whales feeding in the deep but releasing themselves near the surface, sea birds feeding on fish but leaving their droppings on land, and terrestrial megafauna moving their goodies uphill.
That's what I called the great megapoo escalator a year ago - needless to say that we humans not only fail to comply with this mechanism but also are in the process of destroying it by eradicating megafauna, which before our time made the largest contribution to this nutrient recycling.
Read my feature in the open archives here.
Seabirds provide an important flow of nutrients from sea to land, acting against the draining that occurs through rivers and runoff from the land. The image shows guillemots, shags and kittiwakes breeding on the Farne Islands. (Photo: Jamumiwa/Wikimedia Commons.)
