Global mismatches in aboveground and belowground biodiversity.

Human activities are accelerating global biodiversity change and have resulted in severely threatened ecosystem services. A large proportion of terrestrial biodiversity is harbored by soil, but soil biodiversity has been omitted from many global biodiversity assessments and conservation actions, and understanding of global patterns of soil biodiversity remains limited. In particular, the extent to which hotspots and coldspots of aboveground and soil biodiversity overlap is not clear.

Long-lived association between Avalonia and the Meguma terrane deduced from zircon geochronology of metasedimentary granulites.

The Acadian Orogeny of the Northern Appalachians was caused by accretion of the peri-Gondwanan terranes Avalonia and Meguma to the eastern margin of Laurentia during the Devonian. The lithotectonic relationship between Avalonia and Meguma prior to accretion is uncertain. Radioisotopic dating of detrital zircons from metasedimentary granulite xenoliths from the structural basement to the Meguma terrane indicates that Avalonia and Meguma were proximal and likely contiguous as they transited the Rheic Ocean.

Haida Gwaii (British Columbia, Canada): a Phanerozoic analogue of a subduction-unrelated Archean greenstone belt.

Understanding the formation and evolution of Precambrian greenstone belts is hampered by gaps in the rock record and the uncertainty of the tectonic regime that was operating at the time. Thus identifying a modern analogue of a Precambrian greenstone belt can be problematic. In this paper we present geological, geochemical and petrological evidence outlining the case for Haida Gwaii (British Columbia, Canada) as a modern example of a greenstone belt.

First Spectroscopy of the Near Drip-line Nucleus ^{40}Mg.

One of the most exotic light neutron-rich nuclei currently accessible for experimental study is ^{40}Mg, which lies at the intersection of the nucleon magic number N=28 and the neutron drip line. Low-lying excited states of ^{40}Mg have been studied for the first time following a one-proton removal reaction from ^{41}Al, performed at the Radioactive Isotope Beam Factory of RIKEN Nishina Center with the DALI2 γ-ray array and the ZeroDegree spectrometer. Two γ-ray transitions were observed, suggesting an excitation spectrum that shows unexpected properties as compared to both the systematics along the Z=12, N≥20  Mg isotopes and available state-of-the-art theoretical model predictions.

Towards Neutron Capture on Exotic Nuclei: Demonstrating (d,pγ) as a Surrogate Reaction for (n,γ).

The neutron-capture reaction plays a critical role in the synthesis of the elements in stars and is important for societal applications including nuclear power generation and stockpile-stewardship science. However, it is difficult-if not impossible-to directly measure neutron capture cross sections for the exotic, short-lived nuclei that participate in these processes. In this Letter we demonstrate a new technique which can be used to indirectly determine neutron-capture cross sections for exotic systems.

The dynamics of institutional innovation: Crafting co-management in small-scale fisheries through action research.

This paper investigates the dynamics of institutional development and co-management performance in small-scale fisheries. The study covers different contexts and spatial and temporal scales, for nine case studies in the South Pacific. In these cases, new co-management institutions were intentionally set up from 2008 to 2016 through fishery policy intervention to address over-exploitation problems of sea cucumber resources.

Training attention for conscious non-REM sleep: The yogic practice of yoga-nidrā and its implications for neuroscience research.

The study of consciousness within cognitive neuroscience has been dominated in recent years by investigations originating from collaborations between neuroscientific investigators and Buddhist meditation practitioners. The results have been remarkable, particularly when quantitative and qualitative research methods have been combined as they are in the neurophenomenological methodology originated by Francisco Varela. The addition of qualitative data about the experience of the subject greatly enriches the interpretive potential of quantitative data and honors the ultimate subjectivity of all phenomena, if we accept consciousness as the universal first principle as some quantum physicists now do.

Realizing the Focus of the Discipline: Facilitating Humanization in PhD Education: A Student Exemplar Integrating Nature and Health.

Doctorally prepared nurses must be able to represent the unique nursing perspective within interdisciplinary teams to address contemporary health challenges. This article provides a student exemplar applying the unifying focus of facilitating humanization as described by Willis, Grace, and Roy to science on nature and health. As scientific knowledge becomes more complex, nurses must be skilled in translating information through the nursing lens to support individuals in realizing meaning, choice, quality of life, and healing in living and dying.

Values related to professionalism in dental education at the University of Chile: Student and faculty perceptions.

Objective: It is recognised that professionalism should play a central role in dental education. However, its implementation into the curricula of dental schools is still limited. Our objective was to identify the main values related to professionalism based on the perceptions of students and faculty members from the Faculty of Dentistry, University of Chile.

Advanced glycation end-product cross-linking inhibits biomechanical plasticity and characteristic failure morphology of native tendon.

Advanced glycation end-products (AGEs) are formed in vivo from the nonenzymatic reaction between sugars and proteins. AGEs accumulate in long-lived tissues like tendons, cross-linking neighboring collagen molecules, and are in part complicit in connective tissue pathologies experienced in aging and with diabetes. We have previously described discrete plasticity: a characteristic form of nanoscale collagen fibril damage consisting of serial fibril kinking and collagen denaturation that occurs in some mechanically overloaded tendons.

Too little, too much or just right: Injury/illness sensitivity and intentions to drink as a basis for alcohol consumer segmentation.

Background: Although alcohol is the most socially accepted drug, little is known about the classification of alcohol consumers into clusters influencing drinking outcomes. Past research has demonstrated that injury/illness sensitivity predicts health protecting behaviors.

Objectives: The present study explored whether alcohol consumers can be classified based on injury/illness sensitivity and intentions to reduce drinking, and whether the identified clusters exhibited meaningful differences in negative affect and drinking levels.

Effects of microsporidiosis and food availability on the two-spotted lady beetle, Adalia bipunctata L., and convergent lady beetle, Hippodamia convergens Guérin-Méneville.

Two species of microsporidia have been described from lady beetles that are commercially available for biological control: Nosema adaliae from the two-spotted lady beetle, Adalia bipunctata L., and Tubulinosema hippodamiae from the convergent lady beetle, Hippodamia convergens Guérin-Méneville. These pathogens delay larval development under controlled conditions, but little is known regarding the effects that microsporidia cause when their hosts are subjected to stressful conditions that are often experienced in nature.

Unravelling the effects of blue light on aerobic methane emissions from canola.

It is now well documented that plants produce methane (CH) under aerobic conditions. However, the nature of methane production in plants and all the potential precursors and environmental factors that can be involved in the process are not fully understood. Earlier studies have suggested several chemical compounds, including the amino acid methionine, as precursors of aerobic methane in plants, but none have explored other amino acids as potential precursors or blue light as a driving force of methane emission.

Significant Excess of Electronlike Events in the MiniBooNE Short-Baseline Neutrino Experiment.

The MiniBooNE experiment at Fermilab reports results from an analysis of ν_{e} appearance data from 12.84×10^{20} protons on target in neutrino mode, an increase of approximately a factor of 2 over previously reported results. A ν_{e} charged-current quasielastic event excess of 381.

Multi-Locus Genome-Wide Association Studies for 14 Main Agronomic Traits in Barley.

The agronomic traits, including morphological and yield component traits, are important in barley breeding programs. In order to reveal the genetic foundation of agronomic traits of interest, in this study 122 doubled haploid lines from a cross between cultivars "Huaai 11" (six-rowed and dwarf) and "Huadamai 6" (two-rowed) were genotyped by 9680 SNPs and phenotyped 14 agronomic traits in 3 years, and the two datasets were used to conduct multi-locus genome-wide association studies. As a result, 913 quantitative trait nucleotides (QTNs) were identified by five multi-locus GWAS methods to be associated with the above 14 traits and their best linear unbiased predictions.

Nursing Knowledge in the 21st Century: Domain-Derived and Basic Science Practice-Shaped.

Some have described that nursing is at a crossroads that necessitates finding ways to balance knowledge development that is philosophical and conceptual/theoretical with the empirical inquiry, particularly of the developing related biologic sciences. This article sets a direction for nursing knowledge development that is domain-driven. The central role of nursing theory in attaining the common goals of nursing is envisioned.

Manipulating plant phylogenetic diversity for green roof ecosystem service delivery.

Plant species and functional trait diversity have each been shown to improve green roof services. Species and trait differences that contribute to ecosystem services are the product of past evolutionary change and phylogenetic diversity (PD), which quantifies the relatedness among species within a community. In this study, we present an experimental framework to assess the contribution of plant community PD for green roof ecosystem service delivery, and data from one season that support our hypotheses that PD would be positively correlated with two services: building cooling and rainwater management.

Stigma associated with mental illness among Asian men in Vancouver, Canada.

Background:: Due to racism, xenophobic nationalism, acculturation pressures and patriarchal social relations, Asian men in Western societies may be particularly susceptible to negative experiences and beliefs regarding mental illness and treatment services.

Aims:: We examine factors associated with stigma toward mental illness among Asian men in Canada.

Methods:: Between 2013 and 2017, 428 self-identified Asian men living in proximity to Vancouver, Canada, were recruited and completed self-administered questionnaires assessing social stigma and self-stigma.

Interspecific differences in the bioaccumulation of arsenic of three Patagonian top predator fish: Organ distribution and arsenic speciation.

Interspecific differences in arsenic bioaccumulation and organ distribution (muscle, liver, kidney and gills) in three predator fish (creole perch, rainbow trout and brown trout) from a Patagonian lake impacted by volcanic eruptions were studied. Arsenic in fish organs were compared analyzing: 1) temporal (before and after volcanic eruption) and spatial (near and far from the volcano) influence of Puyehue-Cordón Caulle volcanic complex activity on arsenic concentrations; 2) the influence of growth (as total length), organ type and their interactions over arsenic accumulation; and 3) arsenic speciation and total arsenic relationship with carbon to nitrogen ratios (C:N), as a proxy of lipid presence, in fish muscle. In general, total arsenic concentrations in creole perch organs were 2-7 times higher than those recorded in the corresponding organs of salmonids.

Transcriptome and miRNAs analyses enhance our understanding of the evolutionary advantages of polyploidy.

Polyploid organisms have more than two sets of chromosomes, including autopolyploid via intraspecific genome doubling, and allopolyploid via merging genomes of distinct species by hybridization. Polyploid organisms are widespread in plants, indicating that polyploidy has some evolutionary advantages over its diploid ancestor. Actually, polyploidy is always tightly associated with hybrid vigor and adaptation to adverse environmental conditions.

Methods: Fifty-five subjects (27 Pilates intervention, 28 control; 38 females, 17 males; mean age 77.

Combining tensile testing and structural analysis at the single collagen fibril level.

Tensile testing to failure followed by imaging is a simple way of studying the structure-function relationship of connective tissues such as skin, tendon, and ligament. However, interpretation of these datasets is complex due to the hierarchical structures of the tissues spanning six or more orders of magnitude in length scale. Here we present a dataset obtained through the same scheme at the single collagen fibril level, the fundamental tensile element of load-bearing tissues.

Electrochemical Surface-Enhanced Raman Spectroscopy as a Platform for Bacterial Detection and Identification.

The field of bacterial screening is in need of a rapid, easy to use, sensitive, and selective platform for bacterial detection and identification. Current methods of bacterial identification lack time efficiency, resulting in problems for many sectors of society. Surface-enhanced Raman spectroscopy (SERS) has been investigated as a possible candidate for bacterial screening due to its demonstrated ability to detect biological molecules with a high degree of sensitivity.

The Competition of Homophily and Popularity in Growing and Evolving Social Networks.

Previous studies have used several models to investigate the mechanisms for growing and evolving real social networks. These models have been widely used to simulate large networks in many applications. In this paper, based on the evolutionary mechanisms of homophily and popularity, we propose a new generation model for growing and evolving social networks, namely, the Homophily-Popularity model.

The influence of autonomy on personal support workers' job satisfaction, capacity to care, and intention to stay.

Using survey data collected in Ontario, Canada, we explore the impacts of autonomy on community-based Personal Support Workers' intrinsic job satisfaction, capacity to care for and about clients, and intention to continue working in home care. Autonomy was measured as "freedom to decide how to do your job" and "working on your own." Findings show that freedom to do your job and working on your own are both positively associated with job satisfaction and capacity to care, and indirectly increase intention to stay through their relationships with job satisfaction and capacity to care.
