An observation of aquatic surface respiration by Central Stoneroller (Campostoma anomalum) in isolated pools during severe drought

Abstract

Prairie stream fishes have adaptations to contend with seasonal stream drying, however, drought can exacerbate drying and present fishes with harsh environmental conditions. Here, I describe the harsh conditions in an isolated pool and the first observations of Central Stoneroller (Campostoma anomalum) shifting to aquatic surface respiration as a means to deal with low oxygen conditions.
