Splendid isolation in Thingvallavatn / David G. Campbell.
Title: | Splendid isolation in Thingvallavatn / David G. Campbell. |
Author(s): | Campbell, David G. |
Date: | 1996. |
In: | Natural History. (1996.), Vol. 6 (1996) |
Abstract: | Article describes geological setting of Iceland's largest and clearest lake, which has enabled Arctic char - Salvelinus alpinus - to evolve into four morphs, which appear not to inter-breed. Lake's varied topography is described, in turn enabling morphs to live differently. Such "resource polymorphism" is not unique, but youth of lake's ecosystem is one reason for uniquely intensive study. |
Notes: | Natural History. Vol. 6 :48-55 (1996). |
Keywords: | 574 -- Ecology. 574.5(28) -- Freshwater ecology. 597.553.2 -- Salmoniformes: Salvelinus alpinus. H4 -- Zoology: fish. (*3) -- Arctic regions. (*35) -- Iceland. |
