“…GENESYS software (Corbin & Wilkie, 1988) was used for calculations of allelic frequencies, observed heterozygosities and expected heterozygosities (with corrections for sample size; Nei, 1978), F IS for each polymorphic locus, and F ST values; calculation of F-statistics was based on Wright (1978).…”

Genetic variation in European starlings in North America was examined using enzyme electrophoresis and compared to that in their home range. The effect of the founding bottleneck matched theoretical predictions. Heterozygosity was unaffected, whereas allelic diversity may have decreased. Results from this study and others suggest that theoretical predictions of bottlenecks are robust for allozyme data, and applicable under a wide variety of conditions.

“…1. pugetensis along the north coast of California. The region of change from nuttalli songs to pugetensis songs lies north of the zone of intergradation in morphological, physiological, and allozyme characters (Banks 1964;Mewaldt et al 1968;Corbin 1981;Corbin and Wilkie 1988). The initial contact between nuttalli and pugetensis may date from the Late Pleistocene (Baker et al 1984).…”

“…However, he does not suggest why genetic introgression northward from the proposed contact point has not occurred, although the differences in migratory behavior of the two subspecies may be important. Furthermore, Corbin and Wilkie (1988) have shown that gene flow is high among all the coastal populations, with up to seven migrants per generation between populations having the greatest song dialect differences.…”

LEIN, M. R., and CORBIN, K. W. 1990. Song and plumage phenotypes in a contact zone between subspecies of the White-crowned Sparrow (Zonotrichia leucophrys) . Can. J. Zool. 69: 2625-2629.We examined the transitions in a plumage character (lore color) and a learned behavioral character (song pattern) across a 400-km intergrade zone between two subspecies of the White-crowned Sparrow (Zonotrichia leucophrys) in southwestern Alberta. The proportion of birds with black lores, characteristic of Z. I. oriantha, shifted gradually from over 80% in southernmost localities to less than 20% at the northern end of the zone, where most individuals had grey lores, characteristic of Z. I. gambelii. The song pattern of males also showed a complete transition across the zone, but the change was significantly more abrupt than for lore color, occurring over 50-100 km in the center of the intergrade zone. We suggest that this apparent difference in degree of introgression between the two characters may result either from differential dispersal of males and females or from switches in the song patterns of young males that immigrate into populations in which a different song type predominates. Our findings indicate that male song pattern may not be an accurate.indicator of the genetic history of populations in this species.LEIN, M. R., et CORBIN, K. W. 1990. Song and plumage phenotypes in a contact zone between subspecies of the White-crowned Sparrow (Zonotrichia leucophrys). Can. J. Zool. 69 : 2625-2629. Nous avons examine les changements d'une caracteristique du plumage (coloration des lores) et d'un comportement d'apprentisage (ie chant) dans une zone de transition de 400km entre deux sous-especes de Bruants a couronne blanche (Zonotrichia leucophrys) dans le sud-ouest de 1'Alberta. La proportion d'oiseaux a lores noires caracteristiques de Z. I. oriantha, passe graduellement de plus de 80% dans les localites les plus australes, a moins de 20% a la limite boreale de la zone, oh la plupart des individus ont les lores de couleur grise, caracteristiques de Z. I. gambelii. Les caracteristiques du chant des miles subissent Cgalement des changements complets dans la zone, mais le changement est significativement plus brusque que dans le cas de la coloration, puisque la transition se fait sur une distance de 50-100 km au milieu de la zone d'intergradation. 11 est possible que la difference dans l'importance de l'introgression entre les deux caracteristiques provienne de la dispersion differente des miles et des femelles, ou de l'adoption d'un nouveau chant chez les jeunes miles qui migrent au sein de populations oh un type de chant different predomine. Nos resultats indiquent que le chant des miles n'est probablement pas un bon indicateur de l'evolution genetique des populations chez ette espece.[Traduit par la revue]

“…The subspecies to the south (Zonotrichia leucophrys nuttalli) is comprised primarily of non-migratory birds whereas the subspecies to the north (Zonotrichia leucophrys pugetensis) tends to be migratory (Blanchard, 1941). There are clinal shifts in bill length, toe length and tarsus length between the two subspecies (Banks, 1964), which are thought to have diverged in Pleistocene glacial refugia, although phenotypic intermediates abound and no allozymic differences have been detected (Corbin, 1981;Corbin and Wilkie, 1988). We chose 10 individuals from each of the two subspecies from populations located away from the transition zone.…”

a b s t r a c tNext generation sequencing (NGS) technologies are revolutionizing many biological disciplines but have been slow to take root in phylogeography. This is partly due to the difficulty of using NGS to sequence orthologous DNA fragments for many individuals at low cost. We explore cases of recent divergence in four phylogenetically diverse avian systems using a method for quick and cost-effective generation of primary DNA sequence data using pyrosequencing. NGS data were processed using an analytical pipeline that reduces many reads into two called alleles per locus per individual. Using single nucleotide polymorphisms (SNPs) mined from the loci, we detected population differentiation in each of the four bird systems, including: a case of ecological speciation in rails (Rallus); a rapid postglacial radiation in the genus Junco; recent in situ speciation among hummingbirds (Trochilus) in Jamaica; and subspecies of white-crowned sparrows (Zonotrichia leucophrys) along the Pacific coast. The number of recovered loci aligning closely to chromosomal locations on the zebra finch (Taeniopygia guttata) genome was highly correlated to the size of the chromosome, suggesting that loci are randomly distributed throughout the genome. Using eight loci found in Zonotrichia and Junco lineages, we were also able to generate a species tree of these sparrow sister genera, demonstrating the potential of this method for generating data amenable to coalescent-based analysis. We discuss improvements that should enhance the method's utility for primary data generation.
