Ecology of sympatric whitefish (Coregonus lavaretus (L.)) forms in a subarctic lake
This thesis concerns the ecology of sympatric whitefish (Coregonus lavaretus (L.)) forms in a subarctic lake, northern Finland. Despite of rather common occurrence of sympatric whitefish forms in the northern hemisphere, limited amount of information exist about their ecology and morphological divergence. Furthermore, whitefish form data is usually gathered in various different lakes and collec...
متن کاملHuman-induced changes in the reproductive traits of Lake Constance common whitefish (Coregonus lavaretus).
Size-selective fishery harvest leads to phenotypic changes in fish reproductive traits. When these changes represent an evolutionary response of a stock, they may have severe consequences for future stock dynamics and yields. In freshwater ecosystems, reproductive traits may also be affected by other human impacts such as changes in system productivity. The present study uses regression analysi...
متن کاملAlizarin marking of whitefish, Coregonus lavaretus otoliths during egg incubation
Alizarin red S from 200 to 5000 mg L was used to mark the otoliths of whitefish embryos Coregonus lavaretus (L.) from 5 days after fertilization until shortly before hatching, to develop a method for evaluating the effect of stocking whitefish. Mark quality depended on developmental stage at the time of immersion. The best results were obtained when the otolith primordia had formed and had star...
متن کاملMorphological divergence and origin of sympatric populations of European whitefish (Coregonus lavaretus L.) in Lake Femund, Norway.
Combining morphological and genetic analysis, we compared patterns of diversification within and between morphs among sympatric European whitefish (Coregonus lavaretus L.) populations in Lake Femund, Norway. Seven external populations, from potential colonization routes into Lake Femund were included. We found that deep-, shallow-, river- and bay spawning populations are distinct morphs in Lake...
متن کاملTemporal spawning divergence in European whitefish (Coregonus lavaretus)
A critical step in ecological speciation is the development of reproductive isolation. The processes leading up to reproductive isolation are difficult to study since they often occur over very long time periods. Populations of European whitefish (Coregonus lavaretus) has gone through reticulate divergent evolution in many Scandinavian lakes during the last 10 000 years. Some populations even e...
