Streszczenie:
Studies of macrogeographic variation in birdsong involve populations incapable of interbreeding because of physical barriers or separation by large distances. Different patterns have emerged from these studies such as (i) little or no variation exists among individuals or populations from the breeding range, (ii) individual variation is greater than among population variation resulting in no geographic structure, (iii) clinal variation, and (iv) macrogeographic variation where all individuals from several populations on the breeding range share a common song type forming a regional dialect or regiolect. I studied macrogeographic variation in song of the Mourning Warbler ( Oporornis philadelphia (A. Wilson, 1810)). The observed pattern was similar to the fourth category of geographic variation with regiolects. A Western regiolect extended from northern Alberta to western Ontario. An Eastern regiolect stretched eastward from western Ontario and Wisconsin to the Gaspé Peninsula and New England, then southward through the Appalachians to West Virginia. Nova Scotia and Newfoundland each had unique regiolects. Finally, I compared these results to other species with regiolects and assessed the ability of some deterministic hypotheses to explain song divergence (e.g., role of morphology, physical barriers, island isolation).

Streszczenie:
Mitochondrial DNA (mtDNA) from 99 meadow voles (Microtus pennsylvanicus) collected in 13 localities and from 2 Townsend's voles (M. townsendii) from a single locality was assayed for restriction fragment length polymorphism (RFLP) with 13 restriction endonucleases. There was evidence of extensive mtDNA sequence heterogeneity within and among meadow vole populations. Thirty-eight different mtDNA composite phenotypes were found. Two common mtDNA composite phenotypes were shared among five populations, the other mtDNA composite phenotypes being characteristic of individual populations. Estimates of nucleon diversity (ĥ) were high (0.303–0.893), as were measures of intrapopulational nucleotide divergence (px values ranged from 0.0 to 0.038). Population fluctuations and periodic dispersal are the likely mechanisms maintaining high mtDNA composite phenotype diversity in meadow vole populations. Overall interpopulational nucleotide divergence (pxy) was also high (values ranged from 0.007 to 0.045). Cluster analysis clearly separates M. pennsylvanicus and M. townsendii and suggests the separation of the meadow vole populations into eastern and central groups, but there is little evidence of structure within the regional groups. Based on the zoogeography of the populations sampled, the mtDNA RFLP data support the differentiation of Microtus pennsylvanicus into at least two previously described subspecies.

Streszczenie:
This project investigated the genetic composition of natural populations of Anadara trapezia in Australia at three spatial scales : i) microgeographic (within an estuary, 50 metres to ~ 6 kilometres); ii) microgeographic (within populations, less than 50 metres); and, iii) macrogeographic (hundreds of kilometres along the coast of Australia). Allozyme polymorphism surveys using cellulose acetate strips have revealed, from 43 enzymes screened, 18 putative polymorphic loci. Comparisons of levels of heterozygosity among enzyme structural groups showed no significant differences, however, monomers were significantly more variable as a group than multimers. Significant differences in the level and distribution of polymorphism among functional groups of enzymes were observed. It appears that selection may be acting at the molecular level, not only on a particular locus, but on a group of functionally similar loci. At the macrogeographic scale, significant departures from random mating were observed in most populations. Significant differences in allele distribution among populations of A. trapezia along the east coast of Australia were found. At the macrogeographic scale, heterogeneity of allele frequencies may depend upon the distance separating the populations and surface water currents. Differentiation among population groups in this study is attributed to changes in the direction of the East Australian Current combined with onshore countercurrents. The systematic status of the disjunct western Australian population of A. trapezia was also evaluated as compared with the east coast populations. No evidence of genetic, hence evolutionary divergence was found. The results have serious implications in the management of fisheries as erroneous assumptions in fisheries management models may lead to depletion and near extinction of marine species. The research stresses the necessity of sampling at multiple scales and replication strategies. It also highlighted the complexities researchers are faced with in studies of marine bivalves, such as the presence of null alleles, deficiencies of heterozygotes, apparent inbreeding and the small geographic scales governing population structure.
