Ecological Character Displacement and Speciation in Sticklebacks
We present evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia. Geological data suggest that the populations… Expand
Ecology and evolution of sympatric sticklebacks (Gasterosteus): evidence for a species-pair in Paxton Lake, Texada Island, British Columbia
- J. Mcphail
- 1 February 1992
Two forms of Gasterosteus coexist in Paxton Lake on Texada Island, British Columbia. One form (benthic) is predominantly a littoral, benthic forager, whereas the other form (limnetic) is an… Expand
Ecology and evolution of sympatric sticklebacks (Gasterosteus): morphological and genetic evidence for a species pair in Enos Lake, British Columbia
- J. Mcphail
- 1 July 1984
Two morphological forms of three-spined stickleback (Gasterosteus) coexist in Enos Lake near Nanoose Bay, Vancouver Island. For convenience, the two forms are referred to as "benthics" and "limneti...
Ecology and evolution of sympatric sticklebacks (Gasterosteus): origin of the species pairs
- J. Mcphail
- 1 March 1993
Pairs of plankton-feeding and benthos-foraging sticklebacks (Gasterosteus aculeatus) (limnetics and benthics) coexist in six small lakes in southwestern British Columbia. In spite of a persistent low… Expand

Abstract We investigated the interplay between natural selection and gene flow in the adaptive divergence of threespine stickleback (Gasterosteus aculeatus) that reside parapatrically in lakes and… Expand
Parapatric lake and stream sticklebacks on northern Vancouver Island: disjunct distribution or parallel evolution?
Morphological analysis of sticklebacks from Misty Lake and its inlet stream (Keogh River system, northern Vancouver Island) reveals two forms of Gasterosteus. Sticklebacks from the lake are large a...

Effect of incubation temperature on the development of five species of Pacific salmon (Oncorhynchus) embryos and alevins
Embryo and alevin survival, time to hatching and emergence, and alevin and fry size of five species of Pacific salmon (Oncorhynchus) were observed at five incubation temperatures (2, 5, 8, 11, and 14… Expand
Variation in Burst and Prolonged Swimming Performance Among British Columbia Populations of Coho Salmon, Oncorhynchus kisutch
Burst swimming tests, using both wild and laboratory-reared juvenile coho salmon, Oncorhynchus kisutch, from three streams (two south coastal British Columbia and one interior), indicated that in the… Expand
