Genetic structure of lake whitefish (Coregonus clupeaformis) in Lake Michigan
Genetic relationships among lake whitefish (Coregonus clupeaformis) spawning aggregates in Lake Michigan were assessed and used to predict a stock or management unit (MU) model for the resource. We hypothesized that distinct spawning aggregates represented potential MUs and that differences at molecular markers underlie population differentiation. Genetic stock identification using 11 microsate...
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 کاملRole of epibenthic resource opportunities in the parallel evolution of lake whitefish species pairs (Coregonus sp.).
Parallel evolution of a dwarf and normal whitefish has been documented in six post-glacial lakes. Here, we relate the structure and seasonal variations of the epibenthic invertebrate communities to the extent of phenotypic differentiation in these species pairs. The highest phenotypic differentiation occurs in lakes characterized by less overlap in size distribution between limnetic and epibent...
متن کاملReal-time PCR identification of lake whitefish Coregonus clupeaformis in the Laurentian Great Lakes.
The purpose of this study was to develop a real-time PCR assay to specifically identify lake whitefish Coregonus clupeaformis in larval fish assemblages based on a 122 bp amplicon from the mitochondrial genome. The efficiency of the reaction, as calculated from the standard curve, was 90.77% with the standard curve having an r(2) value of 0.998. Specificity of the assay provided single melt pea...
متن کاملMicrobiome investigation in the ecological speciation context of lake whitefish (Coregonus clupeaformis) using next-generation sequencing.
Few studies have applied NGS methods to investigate the microbiome of vertebrates in their natural environment and in freshwater fishes in particularly. Here, we used pyrosequencing of the 16S gene rRNA to (i) test for differences in kidney bacterial communities (i.e. microbiota) of dwarf and normal whitefish found as sympatric pairs, (ii) test the hypothesis of higher bacterial diversity in no...
