Temperature limits at the distribution boundaries of four tropical to temperate species of Cladophora (Cladophorales: Chlorophyta) in the North Atlantic ocean
The existence of temperature limits at the geographic distribution boundaries was experimentally examined for four temperate-tropical species of Cladophora (Chlorophyta) in the North Atlantic Ocean; Cladophora vagabunda (L.) van den Hoek, Cladophora dalmatica Kützing, Cladophora albida (Hudson) Kütz...

The existence of temperature limits at the geographic distribution boundaries was experimentally examined for four temperate-tropical species of Cladophora (Chlorophyta) in the North Atlantic Ocean; Cladophora vagabunda (L.) van den Hoek, Cladophora dalmatica Kützing, Cladophora albida (Hudson) Kützing and Cladophora ruchingeri (C. Agardh) Kützing. Experimental evidence suggests that all species are prevented from extending beyond their northern boundaries on both sides of the Atlantic Ocean by summer temperatures between 10 and 15°C, which are too low to provide an adequate growing season. The exception was C. dalmatica, which is restricted by lethal winter temperature on north-eastern American coasts. All except C. dalmatica could tolerate some degree of freezing. The lower growth limit was between 10 and 15°C for all species.
