IS CLIMATE CHANGE CONTRIBUTING TO RANGE REDUCTIONS AND LOCALIZED EXTINCTIONS IN NORTHERN (HALIOTIS KAMTSCHATKANA) AND FLAT (HALIOTIS WALALLENSIS) ABALONES?

The article examines climate change contributing to range reductions and localized extinctions in northern and flat abalones. The section analyzes northern and flat abalone along the Pacific coast of the United States, comparing data with historic records from 30 years ago to test whether there has been a shift in the southern range as would be predicted with ocean warming. It focuses on northern abalone which is a species of concern, has a broad geographic distribution, and was once the basis of important commercial and recreational fisheries.
