Alizarin 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 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...
متن کاملThermal experience during embryogenesis contributes to the induction of dwarfism in whitefish Coregonus lavaretus
Ecotype pairs provide well-suited model systems for study of intraspecific phenotypical diversification of animals. However, little is still known about the processes that account for the development of different forms and sizes within a species, particularly in teleosts. Here, embryos of a normal-growing 'large' form and a dwarf form of whitefish Coregonus lavaretus were incubated at two tempe...
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 کاملSpeciation Reversal in European Whitefish (Coregonus lavaretus (L.)) Caused by Competitor Invasion
Invasion of exotic species has caused the loss of biodiversity and imparts evolutionary and ecological changes in the introduced systems. In northern Fennoscandia, European whitefish (Coregonus lavaretus (L.)) is a highly polymorphic species displaying adaptive radiations into partially reproductively isolated and thus genetically differentiated sympatric morphs utilizing the planktivorous and ...
