Effects of ultraviolet radiation and contaminant-related stressors on Arctic freshwater ecosystems

Article Abstract:

The projected synergistic effects and risks of ultraviolet (UV) radiation and contaminant-related stressors on the structure and function of freshwater ecosystems in the Arctic are discussed. A major increase in the UV radiation levels would cause enhanced damage to organisms by physiological damage and alterations in species composition.

Historical changes in Arctic freshwater ecosystems

Article Abstract:

The latest lake biota and sedimentiological data reflect the general warming trend and has indicated major changes to freshwater characteristics such as ice-cover duration and thermal stratification. Such data offers an excellent baseline against which future effects of climate change could be planned and measured.

General effects of climate change and Arctic fishes and fish populations

Article Abstract:

The effects of climate change on physical habitat of the fishes of the Arctic are discussed. It is observed that temperature signals must be strong enough to project long-term changes in the availability of fish thermal habitat and that available empirical relationships can be used to project sustainable yields.
