Data from: Aerobic scope predicts dominance during early life in a tropical damselfish

Shaun S. Killen, Matthew D. Mitchell, Jodie L. Rummer, Douglas P. Chivers, Maud C. O. Ferrari, Mark I. McCormick & Mark G. Meekan
A range of physiological traits are linked with aggression and dominance within social hierarchies, but the role of individual aerobic capacity in facilitating aggression has seldom been studied. Further, links previously observed between an individual's metabolic rate and aggression level may be context dependent and modulated by factors such as social stress and competitor familiarity. We examined these issues in juvenile Ambon damselfish, Pomacentrus amboinensis, which display intraspecific competition for territories during settlement on coral...

Data from: Differential introgression in a mosaic hybrid zone reveals candidate barrier genes

Erica L. Larson, Jose A. Andres, Steven M. Bogdanowicz & Richard G. Harrison
Hybrid zones act as genomic sieves; although globally advantageous alleles will spread throughout the zone and neutral alleles can be freely exchanged between species, introgression will be restricted for genes that contribute to reproductive barriers or local adaptation. Seminal fluid proteins (SFPs) are known to contribute to reproductive barriers in insects and have been proposed as candidate barrier genes in the hybridizing field crickets G. pennsylvanicus and G. firmus. Here, we have used 125 SNPs...

Data from: Landscape connectivity predicts chronic wasting disease risk in Canada

Barry R. Nobert, Evelyn H. Merrill, Margo J. Pybus, Trent K. Bollinger & Yeen Ten Hwang
Predicting the spatial pattern of disease risk in wild animal populations is important for implementing effective control programmes. We developed a risk model predicting the probability that a deer harvested in a wild population was chronic wasting disease positive (CWD+) and evaluated the importance of landscape connectivity based on deer movements. We quantified landscape connectivity from deer ‘resistance’ to move across the landscape similar to the flow of electrical current across a hypothetical electronic circuit....

Data from: Northern flickers only work when they have to: how individual traits, population size and landscape disturbances affect excavation rates of an ecosystem engineer

Karen Wiebe & Karen L. Wiebe
Woodpeckers are considered ecosystem engineers because they excavate tree cavities which are used subsequently by many species of secondary cavity nesters for breeding. Woodpeckers have the choice of excavating a new hole or reusing an existing one, and this propensity to excavate (e) may affect community dynamics but has rarely been investigated. Using 18 years of data on a population of northern flickers Colaptes auratus, I tested six hypotheses to explain the propensity to excavate...

Data from: Biomarker of burden: feather corticosterone reflects energetic expenditure and allostatic overload in captive waterfowl

David W. Johns, Tracy A. Marchant, Graham D. Fairhurst, John R. Speakman & Robert G. Clark
1.Allostatic load describes the interplay between energetic demand and availability and is highly context dependent, varying between seasons and life history stages. When energy demands exceed physiological set points modulated by glucocorticoid hormones, individuals may experience allostatic overload and transition between stages in sub-optimal physiological states. 2.Corticosterone, the major glucocorticoid hormone regulating energy expenditure in birds, is incorporated into growing feathers (CORTf), and it has been suggested that CORTf reflects long-term records of allostatic load...

Data from: Repeat variants for the SbMATE transporter protect sorghum roots from aluminum toxicity by transcriptional interplay in cis and trans

Janaina O. Melo, Laura G. C. Martins, Beatriz A. Barros, Maiana R. Pimenta, Ubiraci G. P. Lana, Christiane E. M. Duarte, Maria M. Pastina, C. T. Guimaraes, Robert E. Schaffert, Leon V. Kochian, Elizabeth P. B. Fontes & Jurandir Vieira Magalhaes
Acidic soils, where aluminum (Al) toxicity is a major agricultural constraint, are globally widespread and are prevalent in developing countries. In sorghum, the root citrate transporter SbMATE confers Al tolerance by protecting root apices from toxic Al3+, but can exhibit reduced expression when introgressed into different lines. We show that allele-specific SbMATE transactivation occurs and is caused by factors located away from SbMATE. Using expression-QTL mapping and -GWAS, we establish that SbMATE transcription is controlled...

Data from: Temporal dynamics of snowmelt nutrient release from snow–plant residue mixtures: an experimental analysis and mathematical model development

Diogo Costa, Jian Liu, Jennifer Roste & Jane Elliott
Reducing eutrophication in surface water is a major environmental challenge in many countries around the world. In cold Canadian prairie agricultural regions, part of the eutrophication challenge arises during spring snowmelt when a significant portion of the total annual nutrient export occurs, and plant residues can act as a nutrient source instead of a sink. Although the total mass of nutrients released from various crop residues has been studied before, little research has been conducted...

Data from: A survey of invasive plants on grassland soil microbial communities and ecosystem services

Jennifer Bell, Steven Siciliano & Eric Lamb
Invasive plants can cause changes in structure and function of the ecosystem undergoing invasion. Any changes in ecosystem diversity and community composition will likely alter ecosystem services provided by that ecosystem. However, how these ecosystem services may change is poorly understood. To elucidate how these ecosystem services will change with invasion, we sampled 561 plots undergoing invasion by smooth brome (Bromus inermis) and four other invasive species at a native Rough Fescue prairie located near...

Data from: The fading of fear effects due to coral degradation is modulated by community composition

Maud Ferrari, Mark McCormick, Eric Fakan, Randall Barry & Douglas Chivers
An increasing number of coral reefs throughout the world have become degraded as a result of climate change. This degradation has resulted in a significant decline in local biodiversity. Studies have shown that some fishes (non-responders) within these altered habitats are not able to adequately access olfactory cues, specifically chemical alarm cues that are crucial in mediating predation risk. We propose that the inability to access this crucial information is a potential mechanism for increased...

Samira Mafi Moghaddam, Atena Oladzad, Chu Shin Koh, Larissa Ramsay, John Hart, Sujan Mamidi, Genevieve Hoopes, Avinash Sreedasyam, Andrew Wiersma, Dongyan Zhao, Jane Grimwood, John P. Hamilton, Jerry Jenkins, Brieanne Vaillancourt, Joshua C. Wood, Jeremy Schmutz, Sateesh Kahale, Tiomothy Porch, Kirstin E. Bett, C. Robin Buell & Phillip E. McClean
Tepary bean (Phaseolus acutifolis A. Gray), native to the Sonoran Desert, is highly adapted to heat and drought. It is a sister species of common bean (Phaseolus vulgaris L.), the most important legume protein source for direct human consumption, and whose production is threatened by climate change. Analysis of the tepary genome revealed mechanisms for resilience to moderate heat stress and a reduced disease resistance gene repertoire, consistent with adaptation to arid, hot environments. Extensive...

Association between water, sanitation and hygiene (WASH) and child undernutrition in Ethiopia: a hierarchical approach

Biniyam Sahiledengle, Pammla Petrucka, Abera Kumie, Lillian Mwanri, Girma Beressa, Daniel Atlaw, Yohannes Tekalegn, Demisu Zenbaba, Fikreab Desta & Kingsley Emwinyore Agho
Abstract Background Undernutrition is a significant public health challenge and one of the leading causes of child mortality in a wide range of developing countries, including Ethiopia. Poor access to water, sanitation, and hygiene (WASH) facilities commonly contributes to child growth failure. There is a paucity of information on the interrelationship between WASH and child undernutrition (stunting and wasting). This study aimed to assess the association between WASH and undernutrition among under-five-year-old children in Ethiopia....

Adverse health effects and stresses on offspring due to paternal exposure to harmful substances

Jiaqi Sun, Miaomiao Teng, Fengchang Wu, Xiaoli Zhao, Yunxia Li, Lihui Zhao, Wentian Zhao, Keng Po Lai, Kenneth Mei Yee Leung & John P. Giesy
Recent epidemiological investigations report that environmental factors, such as exposure to harmful substances and stress related to unhealthy lifestyles, can result in health risks to organisms. The involvement of paternal exposure to chemicals and stresses, which leads to a negative impact on physiological responses and developmental processes in descendants, has drawn scientific attention. In this comprehensive review, we systematically describe different exposure sources of intergenerational and transgenerational health effects, including smoking, atmospheric fine particulate matter,...

A high-throughput skim-sequencing approach for genotyping, dosage estimation and identifying translocations

Laxman Adhikari, Jesse Poland, Sandesh Shrestha, Shuanyge Wu, Jared Crain, Lianglian Gao, Byron Evers, Duane Wilson, Yoonha Ju, Dal-Hoe Koo, Pierre Hulc, Curtis Pozniak, Sean Walkowiak, Xiaoyun Wang, Jing Wu, Jeffrey Glaubitz, Lee DeHaan & Bernd Friebe
An optimized, high-throughput and cost-effective genotyping method applicable to various crop breeding populations is very important in this genomic era. We have developed an optimized Nextera skim-sequencing (skim-seq) approach to genotype different populations that can be used for genetics studies and genomics-assisted breeding. We performed skim-seq on a variety of populations developed through doubled haploid (DH) technology, inter-specific recombinants developed through introgression, amphidiploid developed through wide crosses, and on known monosomic samples. 1. A doubled...

A horizontally transmitted Parasitoid Killing Factor protects insects from parasitoids

Martin Erlandson, Edyta Sieminska, Cathy Coutu, Dwayne Hegedus, David Theilmann, Doug Baldwin & Stephanie Harris
Interkingdom competition occurs between hymenopteran parasitoids and insect viruses sharing the same insect hosts. It has been assumed that parasitoid larvae die with the death of infected host or as result of competition for host resources. Herein we describe a gene family, parasitoid killing factor (pkf), that encodes proteins toxic to parasitoids of the Microgastrinae group and determines parasitism success. Pkfs are found in several entomopathogenic DNA virus families and in some lepidopteran genomes. We...

Re-assessment of the climatic controls on the carbon and water fluxes of a boreal aspen forest over 1996-2016: changing sensitivity to long-term climatic conditions

Peng Liu, Alan Barr, Tianshan Zha, T Black, Rachhpal Jassal, Zoran Nesic, Warren Helgason, Xin Jia & Yun Tian
Recent evidence suggests that the relationships between climate and boreal tree growth are generally non-stationary; however, it remains uncertain whether the relationships between climate and carbon (C) fluxes of boreal forests are stationary or have changed over recent decades. In this study, we used continuous eddy-covariance and microclimate data over 21 years (1996-2016) from a 100-year-old trembling aspen stand in central Saskatchewan, Canada to assess the relationships between climate and ecosystem C and water fluxes....

Genome-wide association study uncovers major genetic loci associated with flowering time in response to active accumulated temperature in wild soybean population

Guang Yang, Wei Li, Chao Fan, Miao Liu, Jianxin Liu, Wenwei Liang, Ling Wang, Shufeng Di, Chao Fang, Haiyang Li, Guohua Ding, Yingdong Bi & Yongcai Lai
Abstract Flowering time and active accumulated temperature (AAT) are two key factors that limit the expanded production especially for soybean across different regions. Wild soybean provides an important germplasm for functional genomics study in cultivar soybean. However, the studies on genetic basis underlying flowering time in response to AAT especially in wild soybean were rarely reported. In this study, we used 294 wild soybean accessions derived from major soybean production region characterized by different AAT...

A review on the application of the exposome paradigm to unveil the environmental determinants of age-related diseases

Enmin Ding, Yu Wang, Juan Liu, Song Tang & Xiaoming Shi
Abstract Age-related diseases account for almost half of all diseases among adults worldwide, and their incidence is substantially affected by the exposome, which is the sum of all exogenous and endogenous environmental exposures and the human body’s response to these exposures throughout the entire lifespan. Herein, we perform a comprehensive review of the epidemiological literature to determine the key elements of the exposome that affect the development of age-related diseases and the roles of aging...
