- Climate Change Implicated in Decline of Horseshoe CrabsLEETOWN, W. Va. — A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes. The new research also indicates that horseshoe crabs numbers may continue to decline in the future because of predi […]
- An island's rebirth: Life emerges after a catastrophic volcanic eruptionAnchorage, Alaska — A secluded island in the Aleutian chain is revealing secrets of how land and marine ecosystems react to and recover from a catastrophic volcanic eruption that appeared at first glance to destroy all life on the island. Yet little by little – a wingless beetle here, a tuft of grass there, Kasatochi, an island in the Alaska Maritime Nat […]
