“…Whereas nuclear copies of mitochondrial genes have been reported in other seabirds, murrelet sequences did not differ from the patterns expected for true mtDNA (Quinn and Wilson 1993;Baker and Marshall 1997;Kidd and Friesen 1998a): the tRNA glu sequence could be folded into a clover-leaf structure appropriate for a functional tRNA for glutamic acid (Desjardins and Morais 1990); sequences of the F, D and C boxes differed little from other alcids (pigeon guillemot Cepphus columba, Kidd and Friesen 1998a; common murre Uria aalge, V.L.F. unpubl.…”

Marbled murrelets (Brachyramphus marmoratus) are coastal seabirds that nest from California to the Aleutian Islands. They are declining and considered threatened in several regions. We compared variation in the mitochondrial control region, four nuclear introns and three microsatellite loci among194 murrelets from throughout their range except Washington and Oregon. Significant population genetic structure was found: nine private control region haplotypes and three private intron alleles occurred at high frequency in the Aleutians and California; global estimates of F ST or F ST and most pairwise estimates involving the Aleutians and/or California were significant; and marked isolation-by-distance was found. Given the available samples, murrelets appear to comprise five genetic management units: (1) western Aleutian Islands, (2) central Aleutian Islands, (3) mainland Alaska and British Columbia, (4) northern California, and (5) central California.

“…The ultimate explanation for these di¡erences between humans and birds probably lies in presumed di¡erences in the communicative functions of human language and avian vocalizations. In this study we assayed variation in the ¢rst domain of the control region, the most rapidly evolving portion of the mitochondrial genome (Quinn & Wilson 1993). The rapid accumulation of mutations in this region coupled with the smaller e¡ective population size of the mitochondrial genome (Avise 1994) provides a more sensitive assay of population structure than the allozyme markers used in most previous studies of avian dialects.…”

The relationship between cultural and genetic evolution was examined in the yellow-naped amazon Amazona auropalliata. This species has previously been shown to have regional dialects de¢ned by large shifts in the acoustic structure of its learned contact call. Mitochondrial DNA sequence variation from a 680 base pair segment of the ¢rst domain of the control region was assayed in 41 samples collected from two neighbouring dialects in Costa Rica. The relationship of genetic variation to vocal variation was examined using haplotype analysis, genetic distance analysis, a maximum-likelihood estimator of migration rates and phylogenetic reconstructions. All analyses indicated a high degree of gene £ow and, thus, individual dispersal across dialect boundaries. Calls sampled from sound libraries suggested that temporally stable contact call dialects occur throughout the range of the yellow-naped amazon, while the presence of similar dialects in the sister species Amazona ochrocephala suggests that the propensity to form dialects is ancestral in this clade. These results indicate that genes and culture are not closely associated in the yellow-naped amazon. Rather, they suggest that regional diversity in vocalizations is maintained by selective pressures that promote social learning and allow individual repertoires to conform to local call types.

“…Group extractions (n=16) were conducted with blank controls and all controls were negative when subjected to PCR. Two primer pairs, 521H (Quinn and Wilson 1993)/ 186L (5¢-CCTTATCCACATTTCTCCCAA-3¢) and 272H (5¢-TATGTCTATCGAGCATTCAT-3¢)/16 775L (Quinn 1992) were used to sequence a total of 394 basepairs (bp) from the 5¢ region of the mitochondrial DNA control region. PCR was conducted following described methods (Johnson et al , 2004) with the addition of 1.0 M Betaine to the reaction to improve PCR efficiency.…”

Low genetic variation is often considered to contribute to the extinction of species when they reach small population sizes. In this study we examined the mitochondrial control region from museum specimens of the Heath Hen (Tympanuchus cupido cupido), which went extinct in 1932. Today, the closest living relatives of the Heath Hen, the Greater (T. c. pinnatus), Attwater's (T. c. attwateri) and Lesser (T. pallidicinctus) Prairie-chicken, are declining throughout most of their range in Midwestern North America, and loss of genetic variation is a likely contributor to their decline. Here we show that 30 years prior to their extinction, Heath Hens had low levels of mitochondrial genetic variation when compared with contemporary populations of prairie-chickens. Furthermore, some current populations of Greater Prairie-chickens are isolated and losing genetic variation due to drift. We estimate that these populations will reach the low levels of genetic variation found in Heath Hens within the next 40 years. Genetic variation and fitness can be restored with translocation of individuals from other populations; however, we also show that choosing an appropriate source population for translocation can be difficult without knowledge of historic population bottlenecks and their effect on genetic structure.
