“…About 110,000 years ago, sea levels dropped worldwide, as well as in the Taiwan Strait due to glacial expansion, and the island of Taiwan and the Ryukyu Islands were linked to the Asian mainland by a land bridge which facilitated species exchanges (Yeh et al 2004). The composition of Taiwan's vegetation is highly similar to those of China, Japan, the Philippines, and nearby regions due to alternating periods of exchanges and isolation in the Quaternary.…”

Cinnamomum kanehirae Hayata (Lauraceae), the most valuable subtropical and temperate broadleaf timber tree in Taiwan, is rapidly disappearing from the wild. Taking advantage of a scion garden established by the Taiwan Forestry Research Institute, we examined patterns of chloroplast DNA (cpDNA) variations in 19 populations including 94 individuals. By sequencing two cpDNA fragments using universal primers (the trnL-trnF and petG-trnP intergenic spacers), we found eight polymorphic sites, six haplotypes, and extremely low nucleotide diversity (p = 0.00016) from 792 bp aligned sequences. The ancestral haplotype is widely distributed. Among the populations studied, three separated populations, at Yungfeng, Fuli, and Tahu have high nucleotide diversity. No phylogeographical structures of haplotypes were revealed because the tests of N ST -G ST for populations did not differ from zero in any situations; a 'star-like' genealogy is characteristic when all haplotypes rapidly coalesce and is a general outcome of population expansion. The neutrality test also suggested demographic expansion. The genetic divergence and diversity analyses suggested that two potential refugia existed during the last glaciation with a major one located in southeastern Taiwan and a minor one located in Tahu in north-central Taiwan in the Hsuehshan Range, west of the Central Mountain Range.

“…(Yeh et al 2004;Lee et al 2007Lee et al , 2008. The observed sequence divergences (up to 2.7%) among/within the F. taiwana populations are likely derived from different phylogenetic lineages formed at its early evolutionary stages.…”

“…Studies of the genetic differentiation and insect demography in Taiwan have shown low or no genetic variations between/within populations of some species, including aphid (Hemiptera: Aphididae) (Yeh et al 2005(Yeh et al , 2006, whiteßy (Bemisia argentifolii) (Wang et al 2004a), blowßy (Diptera: Calliphoridae) Shih 2003, Chen et al 2004), rice weevil (Coleoptera: Curculionidae) (Peng et al 2003) and cricket (Loxoblemmus appendicularis) (Yeh et al 2004). However, for crickets, which characteristically often occupy particular geographical regions in Taiwan, genetic differentiation is high between populations separated by long distances but low between neighboring populations and within the same population (Yeh et al 2004).…”

“…5). Considering that Taiwan island was successively connected with and then separated from the Chinese continent during the Pleistocene glaciation cycles, different lineages of F. taiwana might have arrived in Taiwan through similar routes taken by many terrestrial animals to migrate from southern China to Taiwan during these periods (Chung et al 2004;Wang et al 2004b;Yeh et al 2004;Chiang et al 2006;Shih et al 2006Shih et al , 2007.…”

Forcipomyia taiwana (Shiraki), a biting midge, is one of the most annoying blood-sucking pests in Taiwan. In this study, partial DNA sequences of cytochrome c oxidase II from 113 individuals collected from 11 locations around the island were analyzed to delineate the differentiation pattern and possible dispersal processes of F. taiwana in Taiwan. The uncorrected nucleotide divergences, composed of mostly transition substitutions, were high (up to 2.7%) among the samples. Average comparable variations (approximately equal to 0.7%) were found within and between populations. Phylogenetic analysis suggested that several distinct lineages exist and some can be found simultaneously in some populations. A relationship between sequence divergences among populations and their relative geographical distances was observed. Moreover, haplotype diversity was high in all populations, and low to middle levels (Fst = 0.004-0.288) of genetic differentiation were found among populations. Linearized calibration from sequence divergences and phylogenetic analysis showed that different ancestral lineages of F. taiwana possibly emerged as early as 0.6 million years ago. Taken together, genetic exchanges among these divergently ancestral lineages, likely caused by recent artificial events, have possibly led to the similarly diversified compositions of F. taiwana populations all around Taiwan nowadays.
