“…Extended periods of isolation, drift and populationlevel inbreeding may explain why these large, remote island populations showed lower gene diversities, compared to the mainland and islet populations. Island populations that are the most isolated (Nichols et al 2001;Hille et al 2003) and occupy the smallest area (Wayne et al 1991;Lucid and Cook 2004;Petren et al 2005;White and Searle 2007) often show lower levels of gene diversity.…”

Genetic variation is often lower within island populations, however islands may also harbor divergent genetic variation. The likelihood that insular populations are genetically diverse or divergent should be influenced by island size and isolation. We tested this assumption by comparing patterns of genetic variation across all major island song sparrow populations along the Pacific North American coast. Allelic richness was moderately lowered even on islands which are close to large, potential sources. The most significant differences in allelic richness occurred on very small or highly remote islands. Gene diversity was significantly lower only on remote or very small islands. We found that island populations contribute to regional genetic variation through both the amount of genetic variation and the uniqueness of that variation. The partitioning of this contribution was associated with the size and isolation of the island populations.

“…Correlation coefficients were calculated at the individual level for song sparrow populations within: a San Francisco Bay b Salton Sea, c BC, d Southern Gulf Islands. The permuted 95% confidence interval (dashed lines) around the null of r = 0, and the bootstrapped 95% confidence intervals around the correlation for each distance class are also shown Haida Gwaii and the Alexander Archipelago, are located 48 and 16 km respectively off-shore, and are both recognized endemism hotspots (Cook and MacDonald 2001;Cook et al 2006) with multiple examples of genetically divergent populations (Bidlack and Cook 2002;Lucid andCook 2004, Topp andWinker 2008). In Europe, strong divergence between Spanish and Moroccan populations of great buzzards (Otis tarda; Broderick et al 2003) and (Steeves et al 2005).…”

Micro-spatial genetic structure in song sparrows (Melospiza melodia)

The spatial genetic structure of populations is strongly influenced by current and historical patterns of gene flow and drift, which in the simplest case, is limited by geographic distance. We examined the microspatial genetic structure within 33 populations of song sparrows (Melospiza melodia) which included eight subspecies located across coastal areas in southern British Columbia (BC) and California. We also examined the effect of water barriers and local density estimates on genetic structuring. Across both regions, positive genetic structure was detectable at distances of less than 10 km. Genetic divergence was highest in Californian subspecies, perhaps due to reduced gene flow across sub-specific contact zones. In BC, populations distributed across islands displayed greater genetic structuring over similar spatial scales than those across mainland sites, supporting the prediction that water barriers reduce gene flow in this species. Our results confirm both the expectation for fine-scale genetic structure in these generally sedentary subspecies, and the role of landscape features in generating geographic variation in genetic structure.

“…In comparison with those studies, in which Cyt-b were used (), we observed a sequence divergence within species lower than 3.5 and between species higher than 4%. If we consider a divergence sequence ≥3.0 to separate species in ND3-ND4 genes (Nachman et al 1994;Hogan et al 1997;Corneli and Ward 2000;Chirhart et al 2001), genetic divergence found between the NC and the CSC is high (>3.5%) and help to distinguish cryptic species complexes (Peppers et al 2002;Zheng et al 2003;Lucid and Cook 2004;Bradley et al 2004;Shipp-Pennock et al 2005). Additionally, the mismatch distribution indicates the existence of a recent expansion, and support separation of NC as a different species (Peromyscus latirostris Dalquest, 1950).…”

a b s t r a c tSeveral authors have discussed whether Peromyscus furvus is a monotypic species rather than a polytypic entity, that it includes more than one species. Here, we analyze these questions by means of traditional morphometrics and by genetic analyses using ND3-ND4 mtDNA genes as markers. In spite of a generalized overlap of the measurable characters among populations, our analyses show that the northernmost populations, which was assignable to P. latirostris, consistently show larger dimensions overall. The amount of genetic differentiation revealed by our molecular data, support conclusive evidence to suggest this taxon is a valid species. Our results also disclose that morphometric and molecular segregation between P. furvus and P. angustirostris is still incomplete. Finally, the two populations from the state of Oaxaca showed more morphometric affinity with those attributable to P. furvus and revealed a discrete degree of genetic differentiation. Nevertheless, their systematic position is not clear yet.
