Genetic Speciation
Abstract
We know little about the phylogeny and diversity of Tuber species in Japan. We have collected 186 new Tuber ascoma samples in Japan over a 10-year period. The identities and phylogenies of the samples were analyzed by using sequences of four nuclear loci, i.e., internal transcribed spacer (ITS) and...

Abstract
We represent molecular evidence supporting the identification of at least two major lineages (subspecies) within the species of R. opimus in Iran. Analysis of the mitochondrial cytochrome b (cyt b) gene, revealed a range of 1-10% genetic variation among populations, which were well associated with b...

Abstract
Using karyological, allozyme, and molecular genetic analysis, habitation of the four Sylvaemus wood mice species, pygmy wood mouse (S. uralensis), wood mouse (S. sylvaticus), yellow-necked mouse (S. flavicollis), and yellow-bellied mouse (S. fulvipectus) in Rostov oblast was demonstrated. Sylvaemus u...

Abstract
Genetic differentiation and gene geographic variation of house mouse from the territory of Russia and neighboring countries was examined based on the allozyme analysis of samples from natural, semisynanthropic, and obligate synanthropic populations. The results of analysis of genetic differentiation,...

Abstract
Mammalian Prdm9 has been proposed to be a key determinant of the positioning of chromosome double-strand breaks during meiosis, a contributor to speciation processes, and the most rapidly evolving gene in human, and other animal, genomes. Prdm9 genes often exhibit substantial variation in their numbe...

Abstract
We present a Sumatran orang-utan draft genome assembly and short read sequence data from five Sumatran and five Bornean orang-utan genomes. Our analyses reveal that, compared to other primates, the orang-utan genome has many unique features. Structural evolution of the orang-utan genome has proceede...

Abstract
We collected and analyzed data for Sox group B from 36 species of 12 phyla representing the major metazoan clades, with an emphasis on arthropods, to reconstruct the evolutionary history of SoxB in bilaterians and to date the expansion of Sox group B in insects. We found that the genome of the bilat...

Abstract
We study the influence of dominance on the evolution of assortative mating. We perform a population-genetic analysis of a two-locus two-allele model. We consider a quantitative trait that is under a mixture of frequency-independent stabilizing selection and density- and frequency-dependent selection...

Abstract
The associations between pathogens and their hosts are complex and can result from any combination of evolutionary events such as codivergence, switching, and duplication of the pathogen. Mycoviruses are RNA viruses which infect fungi and for which natural vectors are so far unknown. Thus, lateral tr...

Trends in Microbiology (19)1 2011
Abstract
I propose classifying two phylogenetic clusters as separate species only when they have statistically significantly diverged as a result of adaptive evolution. More than a method for classification, the concept of adaptive divergence can be used in a 'reverse ecology' approach to identify lineages t...

We analyze the function of two substitutions in mitochondrial targeting sequences that occurred and rose to high frequency recently during recent human evolution. The ancestral and modern versions of the two targeting sequences do not differ in the efficiency with which they direct a protein to the...

I present a phylogenetic likelihood-based method (quantitative state speciation and extinction [QuaSSE]) that can be used to test such hypotheses using extant character distributions. This approach assumes that diversification follows a birth-death process where speciation and extinction rates may v...

Abstract
We develop a spatially explicit model of geographic range evolution and cladogenesis, where speciation arises via vicariance or peripatry, and explore the effects of these processes on patterns of diversification. We compare the results with those observed in 41 reconstructed avian trees. Our model...

Abstract
We sampled 296 individuals from 13 worldwide populations that are not covered by previous studies. By combining these samples with a data set from our laboratory and the HapMap II samples, we assembled a final dataset of ~250,000 SNPs in 850 individuals from 40 populations. With more uniform samplin...

Abstract
Meristic identification, mitochondrial DNA and a suite of microsatellite markers were employed to estimate the incidence of hybridization in wild populations of anadromous Allis shad Alosa alosa and twaite shad Alosa fallax in southern Irish riverine and estuarine waters. It was shown that 16% of th...

Abstract
We celebrate Charles Darwin's second centenary, and 150 years since the publication of 'The Origin of Species'. After so many years, what has changed in the way we understand Evolution? Obviously we have now a full understanding of the mechanisms underlying heritability. Many molecular tools are ava...

Abstract
I argue that (1) PE suggests, but does not imply, that species selection is a mechanism of evolution; (2) the suggestiveness in this case is not reducible to predictive novelty; (3) species selection is not a metaphorical extension of PE; and (4) getting clear about the way in which PE suggests spec...

Abstract
These results indicate that G. longicollis morphs will introgress rather than diverge towards speciation. The lack of strong assortative mating, particularly at high densities, is predicted to result in the loss of rare morphs within populations, and indicates that spatial and temporal co-occurrence...

The nuclear gene (c-mos) and mitochondrial genes (CYT B and ND2) sequences, representing 44 phasianid species and 26 genera (mainly distributed in China), were used to study the phylogeny of the genus Perdix, which comprises three partridge species.
