Spiders may not be the pure predators we generally believe, after a study found that some make up a quarter of their diet by eating pollen. Dr Dirk Sanders of the University of Exeter demonstrated that orb web spiders — like the common garden variety — choose to eat pollen even when insects are available. […]

Nitrogen deposition poses threat to diversity of Europe’s forest vegetation

Nitrogen deposition poses threat to diversity of Europe’s forest vegetation

Unless nitrogen emissions are curbed, the diversity of plant communities in Europe’s forests will decrease. Atmospheric nitrogen deposition has already changed the number and richness of forest floor vegetation species in European forests over the last 20-30 years. In particular, the coverage of plant species adapted to nutrient-poor conditions has reduced. However, levels of nitrogen […]
