Rejecting strictly allopatric speciation on a continental island: prolonged postdivergence gene flow between Taiwan (Leucodioptron taewanus, Passeriformes Timaliidae) and Chinese (L. canorum canorum) hwameis
Jing Wen Li,Carol K.L. Yeung,Pi Wen Tsai,Rong Chien Lin,Chia Fen Yeh,Cheng Te Yao,Lianxian Han,Le Manh Hung,Ping Ding,Qishan Wang,Shou Hsien Li +10 more
TL;DR: The findings imply that the role of geographical barrier may be less prominent for the speciation of continental island endemics, and suggest a shift in speciation studies from simply correlating geographical barrier and genetic divergence to examining factors that facilitate and maintain divergence, e.g. differential selection and sexual selection.
Journal ArticleDOI
Projective three-level main effects designs robust to model uncertainty
TL;DR: In this article, a columnwise design procedure is used to construct three-level designs for six factors in 18 runs and the projection efficiencies of these designs are explored and compared with designs obtained from the L 18 orthogonal array.
Journal ArticleDOI
Optimal two-level regular fractional factorial block and split-plot designs
Ching-Shui Cheng,Pi Wen Tsai +1 more
TL;DR: In this paper, a general and unified approach to the selection of regular fractional factorial designs, which can be applied to experiments that are unblocked, blocked or have a split-plot structure, is proposed.
Journal ArticleDOI
Testing Founder Effect Speciation: Divergence Population Genetics of the Spoonbills Platalea regia and Pl. minor (Threskiornithidae, Aves)
Carol K.L. Yeung,Pi Wen Tsai,R. Terry Chesser,Rong Chien Lin,Cheng Te Yao,Xiu Hua Tian,Shou Hsien Li +6 more
TL;DR: The potential importance of evolutionarily labile traits with significant fitness consequences, such as migratory behavior and habitat preference, in facilitating divergence of the spoonbills is discussed.
Journal ArticleDOI
A General Criterion for Factorial Designs Under Model Uncertainty
Pi Wen Tsai,Steven G. Gilmour +1 more
TL;DR: In this paper, the QB criterion, which aims to improve the estimation in as many models as possible by incorporating experimenters' prior knowledge along with an approximation to the As criterion, is presented.
