Data from: Duplication and diversification of trehalase confers evolutionary advantages on lepidopteran insects

Yanyan Zhou, Xiaotong Li, Susumu Katsuma, Yusong Xu, Liangen Shi, Toru Shimada & Huabing Wang
Gene duplication provides a major source of new genes for evolutionary novelty and ecological adaptation. However, the maintenance of duplicated genes and their relevance to adaptive evolution has long been debated. Insect trehalase (Treh) plays key roles in energy metabolism, growth, and stress recovery. Here, we show that the duplication of Treh in Lepidoptera (butterflies and moths) is linked with their adaptation to various environmental stresses. Generally, two Treh genes are present in insects: Treh1...

Data from: Rigorous monitoring of a large-scale marine stock enhancement program demonstrates the need for comprehensive management of fisheries and nursery habitat

Shuichi Kitada, Kaori Nakajima, Katsuyuki Hamasaki, Hirotoshi Shishidou, Robin S. Waples & Hirohisa Kishino
Release of captively-bred individuals into the wild is one of the most popular tools in fisheries, forestry, and wildlife management, and introgression of hatchery-reared animals into wild populations is of global concern. However, research and monitoring of impacts on wild populations are generally lacking, and the benefit of hatcheries for long-term fisheries and conservation goals is unclear. Using spatio-temporal genetic monitoring and a four-dacade time series of catch data, we quantified the effects on the...

Data from: Out of the Orient: Post-Tethyan transoceanic and trans-Arabian routes fostered the spread of Baorini skippers in the Afrotropics

Emmanuel F.A. Toussaint, Roger Vila, Masaya Yago, Hideyuki Chiba, Andrew D. Warren, Kwaku Aduse-Poku, Caroline Storer, Kelly M. Dexter, Kiyoshi Maruyama, David J. Lohman & Akito Y. Kawahara
The origin of taxa presenting a disjunct distribution between Africa and Asia has puzzled biogeographers for more than a century. This biogeographic pattern has been hypothesized to be the result of transoceanic long‐distance dispersal, Oligocene dispersal through forested corridors, Miocene dispersal through the Arabian Peninsula or passive dispersal on the rifting Indian plate. However, it has often been difficult to pinpoint the mechanisms at play. We investigate biotic exchange between the Afrotropics and the Oriental...

Data from: The origin of the central dogma through conflicting multilevel selection

Nobuto Takeuchi & Kunihiko Kaneko
The central dogma of molecular biology rests on two kinds of asymmetry between genomes and enzymes: informatic asymmetry, where information flows from genomes to enzymes but not from enzymes to genomes; and catalytic asymmetry, where enzymes provide chemical catalysis but genomes do not. How did these asymmetries originate? Here, we show that these asymmetries can spontaneously arise from conflict between selection at the molecular level and selection at the cellular level. We developed a model...

Data from: Consistent condom use among highly effective contraceptive users in an HIV-endemic area in rural Kenya

Hodaka Kosugi, Masamine Jimba, Junko Kiriya, Akira Shibanuma & Sam Wafula
Background: Women of reproductive age are at the highest risk of both HIV infection and unintended pregnancy in sub-Saharan Africa. Highly effective contraceptives (HECs) such as hormonal injectable and implants are widely used in this region. HECs are effective for preventing pregnancies. However, unlike condoms, HECs offer no protection against HIV. Dual-method use, or the use of condoms with HECs, is an ideal option to reduce HIV risk but is infrequently practiced. Rather, women tend...

The genetic basis of scale-loss phenotype in the rapid radiation of Takifugu fishes

Kiyoshi Kikuchi, Kim Dong, Wataru Kai, Sho Hosoya, Mana Sato, Aoi Nozawa, Miwa Kuroyanagi, Yuka Jo, Satoshi Tasumi, Hiroaki Suetake & Yuzuru Suzuki
The genetic basis of scale-loss in Takifugu pufferfishes Abstract Rapid radiation associated with phenotypic divergence and convergence provides an opportunity to study the genetic mechanisms of evolution. Here we investigate the genus Takifugu that has undergone explosive radiation relatively recently and contains a subset of closely-related species with a scale-loss phenotype. By using observations during development and genetic mapping approaches, we show that the scale-loss phenotype of two Takifugu species, T. pardalis Temminck & Schlegel...

Contrasting effects of land-use changes on herbivory and pollination networks

Naoto Shinohara, Kei Uchida & Takehito Yoshida
Land-use changes, one of the greatest threats to global biodiversity, can cause under-appreciated effects on ecosystems by altering the structures of interspecific interaction networks. These effects have typically been explored by evaluating interaction networks composed of a single type of interaction. Therefore, it remains unclear whether the different types of interaction networks sharing the same species respond to the same land-use changes in a similar manner. To compare the responses of herbivory and pollination networks...

Data from: Biogeographical network analysis of cretaceous terrestrial tetrapods: a phylogeny-based approach

Tai Kubo
Network methods are widely used to represent and analyse biogeography. It is difficult, however, to convert occurrence data of fossil vertebrates to a biogeographical network, as most species were known from a single locality. A new method for creating a biogeographical network that can incorporate phylogenetic information is proposed in this study, which increases the number of edges in the network of fossil vertebrates and enables the application of various network methods. Using ancestral state...

Data from: Ribosomal RNA gene repeats associate with the nuclear pore complex for maintenance after DNA damage

Chihiro Horigome, Eri Unozawa, Takamasa Ooki & Takehiko Kobayashi
The ribosomal RNA genes (rDNA) comprise a highly repetitive gene cluster. The copy number of genes at this locus can readily change and is therefore one of the most unstable regions of the genome. DNA damage in rDNA occurs after binding of the replication fork blocking protein Fob1 in S phase, which triggers unequal sister chromatid recombination. However, the precise mechanisms by which such DNA double-strand breaks (DSBs) are repaired is not well understood. Here,...

Plant community assembly in suburban vacant lots depends on earthmoving legacy, habitat connectivity, and current mowing frequency

Yoichi Tsuzuki, Tomoyo Koyanagi & Tadashi Miyashita
In suburban regions, vacant lots potentially offer significant opportunities for biodiversity conservation. Recently, in Japan, due to an economic recession, some previously developed lands have become vacant. Little is known, however, about the legacy of earlier earthmoving, which involves topsoil removal and ground levelling before residential construction, on plant community composition in such vacant lots. To understand (dis)assembly processes in vacant lots, we studied 24 grasslands in a suburban region in Japan: 12 grasslands that...

Data from: Convergent evolution of body color between sympatric freshwater fishes via different visual sensory evolution

Javier Montenegro, Koji Mochida, Kumi Matsui, Daniel F. Mokodongan, Bayu K. A. Sumarto, Sjamsu A. Lawelle, Andy B. Nofrianto, Renny K. Hadiaty, Kawilarang W. A. Masengi, Lengxob Yong, Nobuyuki Inomata, Takahiro Irie, Yasuyuki Hashiguchi, Yohey Terai, Jun Kitano & Kazunori Yamahira
Although there are many examples of color evolution potentially driven by sensory drive, only few studies have examined whether distinct species inhabiting the same environments evolve similar body colors via shared sensory mechanisms. In this study, we tested whether two sympatric freshwater fish taxa, halfbeaks of the genus Nomorhamphus and ricefishes of the genus Oryzias in Sulawesi Island, converge in both body color and visual sensitivity. After reconstructing the phylogeny separately for Nomorhamphus and Oryzias...
