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 کاملSerum protein alterations in goats naturally infected with Babesia ovis
This study was conducted to determine the electrophoretic pattern of serum protein in goats infected withBabesia ovis. Serum total protein was calculated and serum electrophoresis from 15 goats naturally infectedwith B. ovis as well as same number of healthy goats was performed. Microscopic examination of Giemsastained peripheral blood smears revealed B. ovis infection. The parasitological diag...
متن کاملEnergy allocation in larval and juvenile Coregonus lavaretus: validation of a bioenergetics model
Food consumption and energy allocation of larval and juvenile whitefish Coregonus lavaretus L. were studied by conducting respirometry experiments at 10, 12 and 15) C. Results from these experiments were compared with those predicted by a bioenergetics model that used observed growth as the major input. The data were used to assess the performance of the model, and evaluate its suitability for ...
متن کاملParallel and non-parallel morphological divergence among foraging specialists in European whitefish (Coregonus lavaretus)
Parallel phenotypic evolution occurs when independent populations evolve similar traits in response to similar selective regimes. However, populations inhabiting similar environments also frequently show some phenotypic differences that result from non-parallel evolution. In this study, we quantified the relative importance of parallel evolution to similar foraging regimes and non-parallel lake...
