Data from: Parapatric speciation in three islands: dynamics of geographical configuration of allele sharingRyo Yamaguchi & Yoh Iwasa
We studied the time to speciation by geographical isolation for a species living on three islands connected by rare migration. We assumed that incompatibility was controlled by a number of quantitative loci and that individuals differing in loci by more than a threshold did not mix genetically with each other. For each locus, we defined the geographical configuration (GC), which specifies islands with common alleles, and traced the stochastic transitions between different GCs. From these...
Data from: Genetic divergence with ongoing gene flow is maintained by the use of different hosts in phytophagous ladybird beetles genus HenosepilachnaKei W. Matsubayashi, Tetsuo I. Kohyama, Norio Kobayashi, Satoko Yamasaki, Masakazu Kuwajima & Haruo Katakura
Adaptation to different environments can promote population divergence via natural selection even in the presence of gene flow–a phenomenon that typically occurs during ecological speciation. To elucidate how natural selection promotes and maintains population divergence during speciation, we investigated the population genetic structure, degree of gene flow and heterogeneous genomic divergence in three closely related Japanese phytophagous ladybird beetles: Henosepilachna pustulosa, H. niponica and H. yasutomii. These species act as a generalist, a wild thistle...

Donovan Bailey, Lynsey Kovar, Madhugiri Nageswara-Rao, Hannah Banks, RuthP. Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...
Data from: Experimental evidence that primate trichromacy is well suited for detecting primate social colour signalsChihiro Hiramatsu, Amanda D. Melin, William L. Allen, Constance Dubuc & James P. Higham
Primate trichromatic colour vision has been hypothesized to be well tuned for detecting variation in facial coloration, which could be due to selection on either signal wavelengths or the sensitivities of the photoreceptors themselves. We provide one of the first empirical tests of this idea by asking whether, when compared with other visual systems, the information obtained through primate trichromatic vision confers an improved ability to detect the changes in facial colour that female macaque...
Data from: Contribution of lianas to community-level canopy transpiration in a warm-temperate forestRyuji Ichihashi, Chen-Way Chiu, Hikaru Komatsu, Tomonori Kume, Yoshinori Shinohara, Makiko Tateishi, Kenji Tsuruta, Kyoichi Otsuki & Chen-Wei Chiu
1. Lianas (woody climbers) have a greater amount of leaves relative to basal area or standing biomass than trees, and very wide vessels that permit efficient water transport. These features suggest that lianas possibly consume proportionally more water through transpiration than trees. Despite their potential importance, researchers have made only limited attempts to evaluate effects of lianas on forest water dynamics. 2. We conducted sap flow measurements for 1 year using a thermal-dissipation method for...
Data from: Reconstruction of the multielement apparatus of the earliest Triassic conodont, Hindeodus parvus, using synchrotron radiation X-ray micro-tomographySachiko Agematsu, Kentaro Uesugi, Hiroyoshi Sano & Katsuo Sashida
Earliest Triassic natural conodont assemblages preserved as impressions on bedding planes occur in a claystone of the Hashikadani Formation, which is part of the Mino Terrane, a Jurassic accretionary complex in Japan. In this study, the apparatus of Hindeodus parvus is reconstructed using synchrotron radiation micro-tomography (SR–μCT). This species has six kinds of elements disposed in 15 positions forming the conodont apparatus. Carminiscaphate, angulate, and makellate forms are settled in pairs in the P1, P2,...
Data from: Species-specific flowering cues among general flowering Shorea species at the Pasoh Research Forest, MalaysiaYu-Yun Chen, Akiko Satake, I-Fang Sun, Yoshiko Kosugi, Makoto Tani, Shinya Numata, Stephen P. Hubbell, Christine Fletcher, Nur Supardi Md.Noor, S. Joseph Wright &
1.In a unique phenomenon restricted to the ever wet forests of Southeast Asia, hundreds of species from dozens of plant families reproduce synchronously at irregular, multi-year intervals. The proximate environmental cues that synchronize these general flowering events have not been evaluated systematically because there have been no long-term, high temporal-resolution, species-level records from the region. 2.We present 13 years of weekly flowering records for five Shorea species as well as daily temperature and rainfall records...
