“…The Miaoli Plateau separates the ''northern population'' (localities 1-10) from the ''central population' ' (localities 11-19), while the central population is separated from the ''southern population'' (localities 20-29) near where the Tropic of Cancer passes through Taiwan. These biogeographic breaks were chosen because they serve as geographic barriers for the distribution of terrestrial fauna in Taiwan, including birds (Hachisuka and Udagawa 1950), frogs (Lue and Lai 1991;Lue et al 1999), lizards (Lin et al 2002;Lin 2003), small mammals (Fang and Lee 2002), and several freshwater fishes (Tzeng 1986;Chen and Fang 1999). Ventral coloration of each snake was defined by quantifying the overall coverage of black coloration of the ventral scales.…”

Differences in coloration between eastern and western populations of the Chinese cobra (Naja atra) in Taiwan have been noted by snake collectors, snake keepers, and users of Chinese traditional medicine, but have never been verified by scientific research. In this study, we quantified the amount of black pigment on ventral scales, and found prominent differences in ventral coloration of populations across Taiwan; populations in eastern Taiwan have black ventral scales while populations in the west are predominantly white. Previous studies have shown a similar east-west population differentiation in regards to venom components. We supplement these data with mitochondrial control region sequences, which show extremely low nucleotide diversity. Black-ventral and white-ventral snakes share major haplotypes and show no genetic differentiation. Nevertheless, moderate Fst and low Nm values between populations indicate low levels of gene flow. With a morphological fixation earlier than mitochondrial sequences on a relatively short evolutionary time scale, ventral coloration is potentially a result of local adaptation. Based upon the results of this study, along with traditional observations, we strongly recommend treating each of the four populations of the Chinese cobra in Taiwan as distinct ESUs. Reintroducing confiscated snakes from the illegal trade back into the wild needs to be halted to prevent artifical gene flow

“…It has a broad latitudinal and elevational distribution covering geographic ranges from northern Indochina to southern Siberia and from the eastern edge of the Tibetan Plateau to coastal China and the island of Taiwan. It occupies various types of habitats in China, while its island subspecies ( P. w. bulomachus ) is also considered to occupy the widest niche of any bird species in Taiwan with an extraordinary elevational distribution from sea level to 3100 m [18,19]. A steep elevational gradient can lead to high environmental heterogeneity (e.g., wide ranges of temperature and partial pressure of oxygen) within a short horizontal distance, which is considered a ‘natural laboratory’ with many resources that can be used to examine adaptive responses of populations to different environmental contexts [20].…”

Characterization of the transcriptome of an ecologically important avian species, the Vinous-throated Parrotbill Paradoxornis webbianus bulomachus (Paradoxornithidae; Aves)

BackgroundAdaptive divergence driven by environmental heterogeneity has long been a fascinating topic in ecology and evolutionary biology. The study of the genetic basis of adaptive divergence has, however, been greatly hampered by a lack of genomic information. The recent development of transcriptome sequencing provides an unprecedented opportunity to generate large amounts of genomic data for detailed investigations of the genetics of adaptive divergence in non-model organisms. Herein, we used the Illumina sequencing platform to sequence the transcriptome of brain and liver tissues from a single individual of the Vinous-throated Parrotbill, Paradoxornis webbianus bulomachus, an ecologically important avian species in Taiwan with a wide elevational range of sea level to 3100 m.ResultsOur 10.1 Gbp of sequences were first assembled based on Zebra Finch (Taeniopygia guttata) and chicken (Gallus gallus) RNA references. The remaining reads were then de novo assembled. After filtering out contigs with low coverage (<10X), we retained 67,791 of 487,336 contigs, which covered approximately 5.3% of the P. w. bulomachus genome. Of 7,779 contigs retained for a top-hit species distribution analysis, the majority (about 86%) were matched to known Zebra Finch and chicken transcripts. We also annotated 6,365 contigs to gene ontology (GO) terms: in total, 122 GO-slim terms were assigned, including biological process (41%), molecular function (32%), and cellular component (27%). Many potential genetic markers for future adaptive genomic studies were also identified: 8,589 single nucleotide polymorphisms, 1,344 simple sequence repeats and 109 candidate genes that might be involved in elevational or climate adaptation.ConclusionsOur study shows that transcriptome data can serve as a rich genetic resource, even for a single run of short-read sequencing from a single individual of a non-model species. This is the first study providing transcriptomic information for species in the avian superfamily Sylvioidea, which comprises more than 1,000 species. Our data can be used to study adaptive divergence in heterogeneous environments and investigate other important ecological and evolutionary questions in parrotbills from different populations and even in other species in the Sylvioidea.

“…The Vinaceous Rosefinch ( Carpodacus vinaceus ) is endemic in East Asia and has two recognized subspecies. The nominate subspecies C. v. vinaceus (Verreaux 1871) is distributed along the eastern edge of the Tibetan Plateau and the Himalayas (China, India, Myanmar and Nepal), whereas subspecies C. v. formosanus (Ogilvie‐Grant 1906, 1911) is restricted to areas in Taiwan’s Central Mountain Range (Hachisuka & Udagawa 1951) (Fig. 1).…”

“…1). In spite of their vastly disjunctive distribution pattern, both subspecies occupy similar habitats, such as the edges of temperate broadleaf or coniferous forests, shrub land and bamboo at an elevation approximately between 1800 and 3500 m (Hachisuka & Udagawa 1951; MacKinnon & Phillipps 2000; Robson 2000).…”

M. (2011). Molecular and morphological evidences reveal a cryptic species in the Vinaceous Rosefinch Carpodacus vinaceus (Fringillidae; Aves).-Zoologica Scripta, 40, 468-478. The Vinaceous Rosefinch (Carpodacus vinaceus) is endemic in East Asia with two recognized subspecies -C. v. vinaceus, distributed along the eastern edge of the Tibetan Plateau and the Himalayas, and C. v. formosanus, restricted to Taiwan's Central Mountain Range. As reflected in a controversial taxonomic history, this vastly disjunctive distribution pattern suggests that the subspecies, having been isolated from each other for a long time, might have diverged, challenging the current taxonomic treatment and calling for possible species delimitation. Sequences of two mitochondrial fragments (mtDNA) and two Z-linked nuclear loci (zDNA) were used to reconstruct the intraspecific phylogeny of C. vinaceous. The mtDNA tree shows that the two subspecies of the vinaceous rosefinch form two exclusively monophyletic clades. All but one zDNA sequences from the nominate subspecies and C. v. formosanus also formed exclusively monophyletic clades (the exceptional zDNA sequence from C. v. vinaceous formed a weakly supported clade with two outgroup species). Moreover, by conducting quantitative comparisons of morphometric traits and male plumage coloration, we found that the two subspecies exhibit distinguishable morphological differences. All the evidence therefore suggests that C. v. formosanus is a cryptic species and that its taxonomic status should be restored to full species. Molecular dating suggests that the two sibling rosefinches split 1.7 ± 0.2 million years ago, providing a point estimate for the historical connectivity of biota between eastern Tibet-Himalayas and montane Taiwan.
