Effects of elevated carbon dioxide on the hematological parameters of a temperate catshark
Abstract Atmospheric CO 2 levels have been rising due to an increase in anthropic activities and its implications over marine ecosystems are unprecedented. The present study focused on the effects of ocean acidification (OA) on key hematological parameters of the juvenile small‐spotted catsharks ( S...
