Data from: Habitat filtering determines the functional niche occupancy of plant communities worldwide

Yuanzhi Li, Bill Shipley, Jodi N. Price, Vinícius De L. Dantas, Riin Tamme, Mark Westoby, Andrew Siefert, Brandon S. Schamp, Marko J. Spasojevic, Vincent Jung, Daniel C. Laughlin, Sarah J. Richardson, Yoann Le Bagousse-Pinguet, Christian Schöb, Antonio Gazol, Honor C. Prentice, Nicolas Gross, Jacob Overton, Marcus V. Cianciaruso, Frédérique Louault, Chiho Kamiyama, Tohru Nakashizuka, Kouki Hikosaka, Takehiro Sasaki, Masatoshi Katabuchi … & Marco A. Batalha
How the patterns of niche occupancy vary from species-poor to species-rich communities is a fundamental question in ecology that has a central bearing on the processes that drive patterns of biodiversity. As species richness increases, habitat filtering should constrain the expansion of total niche volume, while limiting similarity should restrict the degree of niche overlap between species. Here, by explicitly incorporating intraspecific trait variability, we investigate the relationship between functional niche occupancy and species richness...

Data from: Magnitude and direction of stream-forest community interactions change with time scale

Amy Marcarelli, Colden Baxter, Joseph Benjamin, Yo Miyake, Masashi Murakami, Kurt Fausch & Shigeru Nakano
Networks of direct and indirect biotic interactions underpin the complex dynamics and stability of ecological systems, yet experimental and theoretical studies often yield conflicting evidence regarding the direction (positive or negative) or magnitude of these interactions. We revisited pioneering datasets collected at the deciduous forested Horonai Stream and conducted ecosystem-level syntheses to demonstrate that the direction of direct and indirect interactions can change depending on the timescale of observation. Prior experimental studies showed that terrestrial...

Intra-population genetic variation in the level and rhythm of daily activity in Drosophila immigrans

Takahisa Ueno & Yuma Takahashi
Genetic diversity within a population, such as polymorphisms and personality, is considered to improve population performance because such intraspecific variations have the potential to alleviate the competition for a limited resource or the risk of predation and sexual harassment at a population-level. Variation in the level and rhythm of daily activity in a population could also affect population performance by directly altering ecological, social, and sexual interactions among individuals. However, it remains to be elucidated...

Data from: Re-examination of species limits in Aspergillus section Flavipedes using advanced species delimitation methods and description of four new species

František Sklenář, Željko Jurjević, Jos Houbraken, Miroslav Kolařík, Maiken Cavling Arendrup, Karin Meinike Jørgensen, Joao Paulo Zen Siqueira, Josepa Gené, Takashi Yaguchi, Chibundu Ngozi Ezekiel, Cristina Silva Pereira & Vít Hubka
Since the last revision in 2015, the taxonomy of section Flavipedes evolved rapidly along with the availability of new species delimitation techniques. This study aims to re-evaluate the species boundaries of section Flavipedes members using modern delimitation methods applied to an extended set of strains (n=90) collected from various environments. The analysis used DNA sequences of three house-keeping genes (benA, CaM, RPB2) and consisted of two steps: application of several single-locus (GMYC, bGMYC, PTP, bPTP)...

Greenery hypothesis: an evolutionary explanation for why presence/absence of green affects humans

Yuya Fukano & Masashi Soga
A growing body of empirical evidence shows that experiences of nature provide people with psychological benefits (improved cognitive function and mental health). Although our knowledge of the proximate causes of such positive psychological responses of humans to nature has improved, their ultimate (evolutionary) drivers remain poorly understood. Here, we propose a new evolutionary psychological hypothesis – the greenery hypothesis – that integrates recent findings in evolutionary psychiatry with many experimental results that cannot be explained...

Data from: A population genomics insight into the Mediterranean origins of wine yeast domestication

Pedro Almeida, Raquel Barbosa, Polona Zalar, Yumi Imanishi, Kiminori Shimizu, Benedetta Turchetti, Jean-Luc Legras, Marta Serra, Sylvie Dequin, Arnaud Couloux, Julie Guy, Douda Bensasson, Paula Gonçalves & José Paulo Sampaio
The domestication of the wine yeast Saccharomyces cerevisiae is thought to be contemporary with the development and expansion of viticulture along the Mediterranean basin. Until now, the unavailability of wild lineages prevented the identification of the closest wild relatives of wine yeasts. Here, we enlarge the collection of natural lineages and employ whole-genome data of oak-associated wild isolates to study a balanced number of anthropic and natural S. cerevisiae strains. We identified industrial variants and...

Data from: Inconsistency between morphological traits and ancestry of individuals in the hybrid zone between two Rhododendron japonoheptamerum varieties revealed by a genotyping-by-sequencing approach

Ichiro Tamaki, Watanabe Yoichi, Yu Matsuki, Yoshihisa Suyama & Mizuo Mizuno
The morphological traits and genetic backgrounds of hybrid individuals in a hybrid zone reflect the history of that zone. In the hybrid zone between Rhododendron japonoheptamerum var. hondoense (RJH) and R. japonoheptamerum var. kyomaruense (RJK), flower morphological traits that can be used to distinguish the two varieties were measured and leaves were sampled for DNA extraction. Reference populations consisting of pure RJH and RJK were also used. Genotype data for individuals were obtained by the...

Genetic structures across a biogeographical barrier reflect dispersal potential of four Southeast Asian mangrove plant species

Alison Wee, Annika Noreen, Junya Ono, Koji Takayama, Prakash Kumar, Hugh Tan, Mohd Saleh, Tadashi Kajita, Edward Webb, Alison K. S. Wee, Annika M. E. Noreen, Prakash P. Kumar, Hugh T. W. Tan, Mohd N. Saleh & Edward L. Webb
Aim Biogeographic barriers restrict the movement of individuals, resulting in population divergence, genetic differentiation, endemism and speciation. Yet, some barriers demonstrate unequal effect across species depending on species dispersal, which manifests in varying genetic structure. We test the hypotheses that the genetic structure of four coastal mangrove species would reflect differences in dispersal potential across the Malay Peninsula, a major biogeographic barrier in the Indo-West Pacific region. Location Twelve sites from the east and west...

Population transcriptomics reveals the effect of gene flow on the evolution of range limits

Katsunori Tamagawa, Kotone Yoshida, Shiori Ohrui & Yuma Takahashi
One of the most essential question in ecology and evolutionary biology is how spatial distribution is limited in each species on the earth. Theoretically, asymmetric gene flow from core populations is suggested to increase poorly adapted immigrants in population at range edge. The genetic load due to the migration (i.e., migration load) should prevent adaptation to the local habitat, leading to decrease in distribution range via local extinction or the limit of range expansion to...

Mitochondrial polymorphism shapes intrapopulation behavioural variation in wild Drosophila

Takahisa Ueno & Yuma Takahashi
Intrapopulation variation in personality, including activity, boldness, and aggressiveness, is becoming more widely recognised and is hypothesised to substantially affect ecological and evolutionary dynamics. Although previous studies utilised candidate-gene approaches and genome-wide association analyses to identify genes correlated with variations in activity and aggressiveness, personality variation may not be fully captured in the nuclear genome, as it does not account for mitochondrial genomes. Mitochondrial genes encode products that are key regulators of the cellular energy-producing...

Changes in transcriptomic response to salinity stress induce the brackish water adaptation in a freshwater snail

Takumi Yokomizo & Yuma Takahashi
Studying mechanisms of the establishment of a population in a novel environment allows us to examine the process of local adaptations and subsequent range expansion. In a river system, detecting genetic or phenotypic differences between a freshwater and brackish water population could contribute to our understanding of the initial process of brackish water adaptations. Here, we investigated behavioral and gene expression responses to the saltwater in a freshwater and brackish water population of the freshwater...

Data from: Elevated mutation rates underlie the evolution of the aquatic plant family Podostemaceae

Natsu Katayama, Satoshi Koi, Akira Sassa, Tetsuya Kurata, Ryoko Imaichi, Masahiro Kato & Tomoaki Nishiyama
Molecular evolutionary rates vary among lineages and influence the evolutionary process. Here, we report elevated genome-wide mutation rates in Podostemaceae, a family of aquatic plants with a unique body plan that allows members to live on submerged rocks in fast-flowing rivers. Molecular evolutionary analyses using 1,640 orthologous gene groups revealed two historical increases in evolutionary rates: the first at the emergence of the family and the second at the emergence of Podostemoideae, which is the...

Data from: The effect of sitagliptin on carotid artery atherosclerosis in Type 2 Diabetes: the PROLOGUE randomized controlled trial

Jun-Ichi Oyama, Koichi Node, Atsushi Tanaka, Toyoaki Murohara, Masafumi Kitakaze, Tomoko Ishizu, Yasunori Sato, Haruo Kamiya, Masaharu Ishihara, Koji Maemura, Hirofumi Tomiyama, Yukihito Higashi, Hirotsugu Yamada, Kentaro Yamashita, Yasuko K. Bando, Shinichiro Ueda & Teruo Inoue
Background: Experimental studies have suggested that dipeptidyl peptidase-4 (DPP-4) inhibitors provide cardiovascular protective effects. We performed a randomized study to evaluate the effects of sitagliptin added on to the conventional therapy compared with conventional therapy alone (diet, exercise, and/or drugs, except for incretin-related agents) on the intima-media thickness (IMT) of the carotid artery, a surrogate marker for the evaluation of atherosclerotic cardiovascular disease, in people with type 2 diabetes mellitus (T2DM). Methods and Findings: We...

OBJECTIVE: To characterize the distribution of tau pathology in patients with amyotrophic lateral sclerosis/parkinsonism-dementia complex on the Kii Peninsula (Kii ALS/PDC) by tau PET using [11C]PBB3 as ligand. METHODS: This is a cross-sectional study of five patients with ALS/PDC and one asymptomatic participant with a dense family history of ALS/PDC from the Kii Peninsula who took part in this study. All were men, and their age was 76 ± 8 (mean ± SD) years. Thirteen...

Data from: Balanced genetic diversity improves population fitness

Yuma Takahashi, Ryoya Tanaka, Daisuke Yamamoto, Noriyuki Suzuki, Masakado Kawata & Suzuki Noriyuki
Although genetic diversity within a population is suggested to improve population-level fitness and productivity, the existence of these effects is controversial because empirical evidence for an ecological effect of genetic diversity and the underlying mechanisms is scarce and incomplete. Here, we show that the natural single-gene behavioural polymorphism (Rover and sitter) in Drosophila melanogaster has a positive effect on population fitness. Our simple numerical model predicted that the fitness of a polymorphic population would be...

Data from: The global distribution of diet breadth in insect herbivores

Matthew L. Forister, Vojtech Novotny, Anna K. Panorska, Leontine Baje, Yves Basset, Philip T. Butterill, Lukas Cizek, Phyllis D. Coley, Francesca Dem, Ivone R. Diniz, Pavel Drozd, Mark Fox, Andrea E. Glassmire, Rebecca Hazen, Jan Hrcek, Joshua P. Jahner, Ondrej Kaman, Tomasz J. Kozubowski, Thomas Kursar, Owen T. Lewis, John Lill, Robert J. Marquis, Scott E. Miller, Helena C. Morais, Masashi Murakami … & Lee A. Dyer
Understanding variation in resource specialization is important for progress on issues that include coevolution, community assembly, ecosystem processes, and the latitudinal gradient of species richness. Herbivorous insects are useful models for studying resource specialization, and the interaction between plants and herbivorous insects is one of the most common and consequential ecological associations on the planet. However, uncertainty persists regarding fundamental features of herbivore diet breadth, including its relationship to latitude and plant species richness. Here...

How co-distribution of two related azaleas (Rhododendron) developed in the Japanese archipelago: Insights from evolutionary and demographic analyses

Watanabe Yoichi, Etsuo Ono, Koichi Uehara, Yoshihiro Tsunamoto, Ayumi Matsuo & Yoshihisa Suyama
Plants growing in similar climates with extensively overlapping distributions may exhibit similar phylogeographic patterns, due to similarities in range shifts during past climatic oscillations. We tested and exploited this expectation in a comparison of the evolutionary and demographic histories of two related and co-distributed species endemic to Japan – Rhododendron pentaphyllum and R. quinquefolium. Genetic variation in sequences of noncoding chloroplast DNA regions and hundreds of nuclear single nucleotide polymorphisms were used to investigate 191...

Data from: Aldosterone reduction rate after saline infusion may be a novel clinical prediction of determining subtypes of primary aldosteronism

Hidekazu Nagano, Takashi Kono, Atsushi Saiga, Yoshihiro Kubota, Masanori Fujimoto, Saul Felizola, Kazuki Ishiwata, Ai Tamura, Seiichiro Higuchi, Ikki Sakuma, Sawako Suzuki, Hisashi Koide, Nobushige Takeshita, Shinichi Sakamoto, Toshiaki Ban, Koutaro Yokote, Yasuhiro Nakamura, Tomohiko Ichikawa, Takashi Uno & Tomoaki Tanaka
ObjectiveAccurate assessment of the localization of aldosterone-producing adenomas (APAs) is essential for the treatment of primary aldosteronism (PA). Although adrenal venous sampling (AVS) is the standard method of reference for subtype diagnosis in PA, controversy exists concerning the criteria for interpretation. This study aimed to determine better indicators that can reliably predict subtypes of PA. MethodRetrospective analysis in single-cohort including 209 patients with PA who were subjected to AVS. 82 patients whose plasma aldosterone concentrations...

Data from: Plant odour and sex pheromone are integral elements of specific mate recognition in an insect herbivore

Felipe Borrero-Echeverry, Marie Bengtsson, Kiyoshi Nakamuta & Peter Witzgall
Specific mate recognition relies on the chemical senses in most animals, and especially in nocturnal insects. Two signal types mediate premating olfactory communication in terrestrial habitats: sex pheromones, which blend into an atmosphere of plant odorants. We show that host plant volatiles affect the perception of sex pheromone in males of the African cotton leafworm Spodoptera littoralis and that pheromone and plant volatiles are not perceived as independent messages. In clean air, S. littoralis males...

Evolutionary effects of geographic and climatic isolation between Rhododendron tsusiophyllum populations on the Izu Islands and mainland Honshu of Japan

Watanabe Yoichi, Minami Takahashi, Atsushi J. Nagano, Koichi Uehara & Harue Abe
Geographic and environmental isolations of islands and the mainland offer excellent opportunity to investigate colonization and survival dynamics of island populations. We inferred and compared evolutionary processes and the demographic history of Rhododendron tsusiophyllum, in the Izu Islands and the much larger island Honshu, treated here as the mainland, using thousands of nuclear SNPs obtained by ddRAD-seq from eight populations of R. tsusiophyllum and three populations of R. tschonoskii as an outgroup. Phylogenetic relationships and...

Discovery of new Trichophyton members, T. persicum and T. spiraliforme spp. nov., as a cause of highly inflammatory tinea cases in Iran and Czechia

Adéla Čmoková, Ali Rezaei-Matehkolaei, Ivana Kuklová, Miroslav Kolařík, Forough Shamsizadeh, Saham Ansari, Maral Gharaghani, Viera Miňovská, Mohammad Javad Najafzadeh, Sadegh Nouripour‐Sisakht, Takashi Yaguchi, Kamiar Zomorodian, Hossein Zarrinfar & Vit Hubka
Pathogens from the Trichophyton benhamiae complex are one of the most important causes of animal mycoses with significant zoonotic potential. In the light of the recently revised taxonomy of this complex, we retrospectively identified 38 Trichophyton isolates that could not be resolved in any of the existing species. These strains were isolated from Iranian and Czech patients during molecular epidemiological surveys on dermatophytosis and were predominantly associated with highly inflammatory tinea corporis cases suggesting possible...

Data from: Tau protein as a diagnostic marker for diffuse axonal injury

Keisuke Tomita, Taka-Aki Nakada, Taku Oshima, Takayuki Motoshima, Rui Kawaguchi & Shigeto Oda
Background: Diffuse axonal injury (DAI) is difficult to identify in the early phase of traumatic brain injury (TBI) using common diagnostic methods. Tau protein is localized specifically in nerve axons. We hypothesized that serum level of tau can be a useful biomarker to diagnose DAI in the early phase of TBI. Methods & Results: We measured serum tau levels in 40 TBI patients who were suspected of DAI within 6 hours after TBI to evaluate...

Data from: Rapid comeback of males: evolution of male-killer suppression in a green lacewing population

Masayuki Hayashi, Masashi Nomura & Daisuke Kageyama
Evolutionary theory predicts that the spread of cytoplasmic sex ratio distorters leads to the evolution of host nuclear suppressors, although there are extremely few empirical observations of this phenomenon. Here, we demonstrate that a nuclear suppressor of a cytoplasmic male killer has spread rapidly in a population of the green lacewing Mallada desjardinsi. An M. desjardinsi population, which was strongly female-biased in 2011 because of a high prevalence of the male-killing Spiroplasma endosymbiont, had a...
