Nitrogen deposition has shifted European forest plant ranges westward over decades

Understory plants in European temperate forests have shifted their ranges westward over decades, with a stronger connection to nitrogen deposition than climate change. Westward shifts were more likely than northward ones and colonized areas along the east-west axis were closely related to nitrogen and sulfur deposition rates.

Students who feel more university connection may be more likely to binge drink

A new study by Penn State researchers found that students who feel a sense of belonging at their university are more likely to binge drink than those who do not. The study, which analyzed data from over 4,000 university students, suggests that feeling connected to the university is associated with higher rates of substance use.
