-We examined geographic differentiation in mitochondrial (mt) DNA and in morphometric characters among 12 populations of the Sharp-tailed Sparrow (Ammodramus caudacutus) representing all recognized subspecies and geographic regions. Both data sets reveal the existence of two distinct groups of populations, a northern group from the Canadian maritime provinces and Maine, the St. Lawrence Valley, Hudson Bay lowlands, and interior prairies, and a southern group from along the Atlantic coast north…

MITOCHONDRIAL DNA VARIATION, SPECIES LIMITS, AND RAPID EVOLUTION OF PLUMAGE COLORATION AND SIZE IN THE SAVANNAH SPARROW
TLDR
The results for Sable Island and Isla San Benito show that size and plumage coloration can evolve rapidly and that the tamaño and coloración of the plumaje pueden evolucionar rápidamente.
Genetic evidence for the effect of a postglacial population expansion on the phylogeography of a North American songbird
TLDR
Support is provided for the Pleistocene expansion hypothesis in MacGillivray's warbler and it is suggested that postglacial expansion of bottlenecked populations is responsible for the lack of variation and structure reported for most North American songbird species.
THE HISTORICAL PATTERN OF GENE FLOW AMONG MIGRATORY AND NONMIGRATORY POPULATIONS OF PRAIRIE WARBLERS (AVES: PARULINAE)
  • C. Buerkle
  • Biology
    Evolution; international journal of organic evolution
  • 1999
TLDR
Genetic evidence for restricted gene flow between migratory and nonmigratory populations of prairie warblers is presented and the phylogenetic relationship of haplotypes suggests that isolation between these forms must have arisen relatively recently in their history.
Ancestral polymorphisms in genetic markers obscure detection of evolutionarily distinct populations in the endangered Florida grasshopper sparrow (Ammodramus savannarum floridanus)
TLDR
It is argued that despite the lack of phylogenetic distinctiveness of floridanus genotypes the observed genetic differentiation and previously documented phenotypic differences justify continued designation of this subspecies as a protected population segment.
NEW MITOCHONDRIAL DNA DATA AFFIRM THE IMPORTANCE OF PLEISTOCENE SPECIATION IN NORTH AMERICAN BIRDS
  • N. K. Johnson, C. Cicero
  • Environmental Science, Biology
    Evolution; international journal of organic evolution
  • 2004
TLDR
It is concluded that the entire Pleistocene, including the last two glacial cycles (<250,000 years ago), was important in speciations of modern North American birds.
Postglacial colonization of the Tibetan plateau inferred from the matrilineal genetic structure of the endemic red‐necked snow finch, Pyrgilauda ruficollis
TLDR
The results suggest that P. ruficollis colonized the Tibetan plateau after the extensive glacial period (0.5–0.175 Ma), expanding from the eastern margin towards the inner plateau, and this colonization occurred without matrilineal population structuring.
CONCORDANCE BETWEEN MORPHOLOGICAL AND MOLECULAR MARKERS IN ASSESSING HYBRIDIZATION BETWEEN SHARP-TAILED SPARROWS IN NEW ENGLAND
TLDR
Hybridization is pivotal in framing ideas about species concepts and has the potential to produce novel genotypes that may serve as starting points for new evolutionary trajectories and support the asymmetrical hybridization hypothesis.
An initial examination of mitochondrial dna structure in Burrowing Owl populations
TLDR
The depth of the split between Burrowing Owls fkom North and South America is consistent with species-level distinction and may date back 2 million yr to the connection of' these continents via the isthmian land bridge.
The role of Pleistocene glaciations in shaping the genetic structure of South American fur seals (Arctocephalus australis)
TLDR
The role that Pleistocene glaciations may have had in shaping the genetic structure currently found in the two southernmost breeding areas of the South American fur seal is evaluated and a pattern of phylogeographic structure with two main haplogroups corresponding to the different breeding areas is revealed.

Patterns of Mitochondrial DNA and Allozyme Evolution in the Avian Genus Ammodramus
TLDR
The genetic pattern was not concordant with an estimate of variation in skeletal morphometrics produced by Robins and Schnell (1971), suggesting that ecological pressures effect convergence in skeletal morphology.

TLDR
Analyses of restriction sites revealed a close phylogenetic affinity of A. m.
Late‐Pleistocene Isolation in Salt‐Marsh Sparrows
TLDR
It is shown that seaside sparrows support the view, based on general relationships, that they probably arose from savanna sparrow stock and in turn evolved sharptails, and the ranges overlap today in the continuous, linear habitat of the Atlantic coast salt marsh.
Mitochondrial DNA and two perspectives on evolutionary genetics
This essay reviews comparative studies of animal mitochondrial DNA (mtDNA), with emphasis on findings made and ideas developed at Berkeley. It argues that such studies are bringing together two
Rapid evolution of animal mitochondrial DNA.
TLDR
The rate of evolution of the mitochondrial genome appears to exceed that of the single-copy fraction of the nuclear genome by a factor of about 10 and is likely to be an extremely useful molecule to employ for high-resolution analysis of the evolutionary process.
Species concepts and speciation
TLDR
It is suggested that it would be preferable to recognize and indeed stress that not all species are of the same kind and to devise a scheme for designating and handling them then in a systematic manner.
Species Concepts and Speciation Analysis
TLDR
A new mechanistic taxonomy of speciation is needed before population genetics, which deals with evolutionary mechanisms, can be properly integrated with speciation theory; that is, the various modes of Speciation should be characterized according to the various forces and genetic mechanisms that underly the evolution of isolating barriers.
DNA fingerprints from hypervariable mitochondrial genotypes.
TLDR
The variable gel profiles provided unique mtDNA "fingerprints" for most conspecific animals assayed and should find special application in the genetic assessment of maternity.
THE RELATIONSHIPS OF SPARROWS IN THE GENERA AMMODRAMUS, PASSERHERBULUS, AND AMMOSPIZA WITH A DESCRIPTION OF A HYBRID LE CONTE'S X SHARP-TAILED SPARROW
TLDR
The evidence of molt, plumage, and voice bearing on the relationships of these species is considered, with the discovery of a hybrid between the Le Conte's and Sharp-tailed Sparrows (described below).
Molecular Evolutionary Genetics
TLDR
Recent developments of statistical methods in molecular phylogenetics are reviewed and it is shown that the mathematical foundations of these methods are not well established, but computer simulations and empirical data indicate that currently used methods produce reasonably good phylogenetic trees when a sufficiently large number of nucleotides or amino acids are used.
