TIME-TEMPERATURE RELATIONS IN THE INCUBATION OF THE WHITEFISH, COREGONUS CLUPEAFORMIS (MITCHILL)

Time-temperature Relations in the Incubation of the Whitefish, Coregonus Clupeaformis (mitchill)

1. Whitefish eggs incubated in aerated lake water at controlled tempera tures of 0 degrees , 0.5 degrees , 2 degrees , 4 degrees , 6 degrees , 8 degrees , 10 degrees , and 12 degrees C., failed to hatch at either 0 degrees or 12 degrees C. 0.6 per cent hatched alive at 10 degrees C., 72.67 per cent hatched alive at 0.5 degrees C., and an intermediate proportion hatched at intermediate temperatu...

The Embryology of the Whitefish Coregonus Clupeaformis, (Mitchill). Part III, The Second Half of the Incubation Period

Parallelism in gene transcription among sympatric lake whitefish (Coregonus clupeaformis Mitchill) ecotypes.

Abstract We tested the hypothesis that phenotypic parallelism between dwarf and normal whitefish ecotypes (Coregonus clupeaformis, Salmonidae) is accompanied by parallelism in gene transcription. The most striking phenotypic differences between these forms implied energetic metabolism and swimming activity. Therefore, we predicted that genes showing parallel expression should mainly belong to f...

Genetically based phenotype-environment association for swimming behavior in lake whitefish ecotypes (Coregonus clupeaformis Mitchill).

Studies of phenotype-environment associations in adaptive radiation have focused largely on morphological traits related to resource-based phenotypic differences. The genetic basis of adaptive behaviors implicated in population divergence remains poorly understood, as few studies have tested the hypothesis of behavioral phenotype-environment associations. We provide evidence of a phenotype-envi...

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...
