Niche evolution underpins the generation and maintenance of biological diversity, but niche conservatism, in which niches remain little changed over time in closely related taxa and the role of ecology in niche evolution are continually debated. To test whether climate niches are conserved in two closely related passerines in East Asia – the vinous-throated (Paradoxornis webbianus) and ashy-throated (P. alphonsianus) parrotbills – we established their potential allopatric and sympatric regions using ecological niche models and...
Data from: Fighting experience alters brain androgen receptor expression dependent on testosterone statusCheng-Yu Li, Ryan L. Earley, Shu-Ping Huang, Yuying Hsu, S.-P. Huang & C.-Y. Li
Contest decisions are influenced by the outcomes of recent fights (winner–loser effects). Steroid hormones and serotonin are closely associated with aggression and therefore probably also play important roles in mediating winner–loser effects. In mangrove rivulus fish, Kryptolebias marmoratus, individuals with higher testosterone (T), 11-ketotestosterone and cortisol levels are more capable of winning, but titres of these hormones do not directly mediate winner–loser effects. In this study, we investigated the effects of winning/losing experiences on brain...
Data from: Influences of environmental and spatial factors on genetic and epigenetic variations in Rhododendron oldhamii (Ericaceae)Chun-Lin Huang, Jui-Hung Chen, Ming-Hsuan Tsang, Jeng-Der Chung, Chung-Te Chang & Shih-Ying Hwang
Test of the relationship of genetic and particularly epigenetic variation with geographic isolation and environment is important to reveal potential environmental drivers for selection. Rhododendron oldhamii is widespread but inhabits fragmented subtropical forest landscapes and populations across its range may exhibit different levels of genetic and epigenetic structuring correlated to their environmental conditions. Here, we investigated the genetic and epigenetic variations and their ecological correlates in R. oldhamii. Genetic and epigenetic variations were surveyed using...
Data from: Influence of gene flow on divergence dating – implications for speciation history of Takydromus grass lizardsShu-Ping Tseng, Shou-Hsien Li, Hurng-Yi Wang, Si-Min Lin & Chia-Hung Hsieh
Dating the time of divergence and understanding speciation processes are central to the study of the evolutionary history of organisms but are notoriously difficult. The difficulty is largely rooted in variations in the ancestral population size or in the genealogy variation across loci. To depict the speciation processes and divergence histories of three monophyletic Takydromus species endemic to Taiwan, we sequenced 20 nuclear loci and combined with one mitochondrial locus published in GenBank. They were...
Data from: Testing hypotheses of mitochondrial gene-tree paraphyly: unraveling mitochondrial capture of the Streak-breasted Scimitar Babbler (Pomatorhinus ruficollis) by the Taiwan Scimitar Babbler (P. musicus)Feng Dong, Fa-Sheng Zou, Fu-Min Lei, Wei Liang, Shou-Hsien Li & Xiao-Jun Yang
Species-level paraphyly inferred from mitochondrial gene trees is a prevalent phenomenon in taxonomy and systematics, but there are several potential causes that are not easily explained by currently used methods. The present study aims to test the underlying causes behind the observed paraphyly of Streak-breasted Scimitar Babbler (Pomatorhinus ruficollis) via statistical analyses of four mitochondrial (mtDNA) and nine nuclear (nuDNA) genes. Mitochondrial gene trees show paraphyly of P. ruficollis with respect to the Taiwan Scimitar...
Spatial variation in pollinator-mediated selection (Δβpoll) is a major driver of floral diversification, but we lack a quantitative understanding of its link to pollen limitation and net selection on floral traits. For 2-5 years, we quantified Δβpoll on floral traits in two populations each of two orchid species differing in pollen limitation. In both species, spatio-temporal variation in Δβpoll explained much of the variation in net selection. Selection was consistently stronger and the proportion that...
