Application of Genealogical-Concordance Principles to the Taxonomy and Evolutionary History of the Sharp-Tailed Sparrow (Ammodramus caudacutus)
@article{Rising1993ApplicationOG, title={Application of Genealogical-Concordance Principles to the Taxonomy and Evolutionary History of the Sharp-Tailed Sparrow (Ammodramus caudacutus)}, author={James D. Rising and John C. Avise}, journal={The Auk}, year={1993}, volume={110}, pages={844-856} }
-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

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.
NORTH AMERICAN BLACK BEAR mtDNA PHYLOGEOGRAPHY: IMPLICATIONS FOR MORPHOLOGY AND THE HAIDA GWAII GLACIAL REFUGIUM CONTROVERSY
- Environmental ScienceEvolution; international journal of organic evolution
- 1997
It is found that the Haida Gwaii bear are indistinguishable from coastal bear of British Columbia and Vancouver Island, but are highly distinct from continental bear, consistent with recent suggestions that a glacial refugium existed on the now submerged continental shelf.
Genetic evidence for the effect of a postglacial population expansion on the phylogeography of a North American songbird
- BiologyProceedings of the Royal Society of London. Series B: Biological Sciences
- 2000
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.
Morphological Adaptation with No Mitochondrial DNA Differentiation in the Coastal Plain Swamp Sparrow
- Environmental Science, Biology
- 1998
A rapid and recent geographic expansion of Swamp Sparrows from restricted Pleistocene populations is suggested, suggesting that selection on the divergent traits is intense.
THE HISTORICAL PATTERN OF GENE FLOW AMONG MIGRATORY AND NONMIGRATORY POPULATIONS OF PRAIRIE WARBLERS (AVES: PARULINAE)
- BiologyEvolution; international journal of organic evolution
- 1999
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)
- Biology, Environmental ScienceMolecular ecology
- 2003
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
- Environmental Science, BiologyEvolution; international journal of organic evolution
- 2004
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
- Biology, Environmental ScienceMolecular ecology
- 2005
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
- Environmental Science, Biology
- 2005
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.

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.

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.

Species concepts and speciation

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
- Biology
- 1983
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.

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

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.
