1 Population Structure Elements of Population Evolution Reproductive isolation (homing to natal sites) Differential natural and sexual selection Heritable traits Results Genetically determined population specific variation Challenges To identify the ecological basis for the variation and the implications for conservation of the populations

2 Population structure and local adaptation Variation in genetic attributes that are neutral to selection are useful for determining current isolation or gene flow, and post-glacial history Variation in traits subject to selection are useful for studying evolution, though the environment also affects trait values

7 Variation in phenotypic traits We can observe differences among populations within species in virtually every phenotypic trait that can be measured, including but not limited to size, shape, color, timing of migration and breeding, egg size, etc.

8 Izaak Walton, The Compleat Angler, 1653, on population-level variation among salmonids: there are several kinds of [brown] Trouts; but these several kinds are not considered but by very few men, for they go under the general name of Trouts: just as Pigeons do in most places; though it is certain there are tame and wild Pigeons: and of the tame, there be Helmits and Runts, and Carriers and Cropers, and indeed too many to name. And t is so with many kinds of fish, and of Trouts especially, which differ in their bigness, and shape, and spots, and color. P. 70

9 Western Alaska rainbow trout

10 Cutthroat trout

11 Local adaptations These phenotypic traits that are under some degree of genetic control They are often assumed to result from local regimes of selection, and referred to as local adaptations. However, the are also affected by environmental conditions in many cases.

12 Criteria for proving local adaptation (Taylor 1991) 1. The trait being investigated must have a genetic basis 2. Different phenotypes must have different fitness 3. A mechanism of selection should be demonstrated

13 Relationship between spawning date and latitude: North American sockeye salmon Median spawning date 28-Dec 28-Nov 29-Oct 29-Sep 30-Aug 31-Jul 1-Jul Hodgson and Quinn 2002 Latitude (N) of the spawning site

22 Isolated populations can evolve as a result of various forms of selection, but how do we explain highly differentiated populations in sympatry? 1) Allopatric divergence, followed by contact through secondary colonization 2) Sympatric divergence 3) Or maybe both?

23 Wisconsin glacial period, about 50,000 to 10,000 years ago McPhail and Lindsey 1970

24 Colonization from the Pacific Refuge

25 Colonization from the Bering Refuge

26 Populations, long isolated in different refuges, may come into contact later, as their ranges expand. Is this why odd and even year pink salmon are so different? Even year pinks are smaller and spawn earlier than odd year pinks in the same river. Beacham and Murray 1985 Males POH length in mm Females River Even Odd Even Odd Glendale Quinsam Puntledge

27 Hypothesized evolution of sockeye, kokanee, and residuals Lakes were colonized after glacial retreat by anadromous sockeye salmon. In rare cases a male did not go to sea. These residuals mated and likely passed to their offspring the tendency not to migrate. Female residuals were not courted by anadromous males, only by residual males. Thus assortative mating began the process of sympatric divergence because the growing conditions (lake vs ocean) caused such differences in size. Later, this pre-zygotic isolation was later reinforced by postzygotic isolation as hybrids of the two forms were less fit than either parental form. Thus kokanee (freshwater progeny of freshwater parents) evolved from residuals (freshwater progeny of anadromous parents).

28 Lough Melvin, Ireland, displays both sympatric divergence and also allopatric origins for brown trout forms. Ferox trout, Lough Corrib (and Melvin, etc.) Sonaghan trout, Lough Melvin Gillaroo, Lough Melvin
