Rocky Mountain wildflower season lengthens by more than a month

A 39-year study reveals that more than two-thirds of alpine flowers have changed their blooming patterns in response to climate change. The blooming season has lengthened by a month, with different species responding in unexpected ways. This change is expected to have strong effects on pollinating insects and migratory birds.

Ancient DNA shows moa were fine until humans arrived

A study analyzing ancient DNA from over 250 radiocarbon-dated moa samples reveals that the iconic New Zealand bird was thriving when humans arrived, contradicting previous theories of population collapse before human arrival. The research suggests human activities contributed to the moa's extinction.
