摘要

There is overwhelming evidence that Earth's climate is changing. These changes are most noticeable in the Arctic, which has recently experienced a dramatic loss of sea-ice cover (1). Altered environments may lead to shifts in the distributions of closely related, formerly isolated species, permitting hybridization (i.e., admixture).
