Information Literacy and Librarians’ Experiences with Teaching Grey Literature to Medical Students and Healthcare Practitioners

Yongtao Lin & Marcus Vaska
The concept of information literacy, which describes the knowledge and skills required in all contexts (i.e. educational sectors, the workplace), as well as in people’s everyday lives in today’s information rich society, was introduced in the United States in the early 1970s. According to the Association of College and Research Libraries Information Literacy Competency Standards for Higher Education (2000), it has been concluded that an information literate individual is able to determine the extent of...

Canoe Reach Geothermal Field

Investigate the structure of the Canoe Reach Geothermal Field near Valemount, British Columbia.

Fernando Campos, Urs Kalbitzer, Amanda Melin, Jeremy Hogan, Saul Cheves, Evin Murillo-Chacon, Adrián Guadamuz, Monica Myers, Colleen Schaffner, Katharine Jack, Filippo Aureli & Linda Fedigan
Extreme climate events can have important consequences for the dynamics of natural populations, and severe droughts are predicted to become more common and intense due to climate change. We analysed infant mortality in relation to drought in two primate species (white-faced capuchins, Cebus capucinus imitator, and Geoffroy's spider monkeys, Ateles geoffroyi) in a tropical dry forest in north-western Costa Rica. Our survival analyses combine several rare and valuable long-term data sets, including long-term primate life-history,...

Data from: Species loss drives ecosystem function in experiments, but in nature the importance of species loss depends on dominance

Mark A. Genung, Jeremy Fox & Rachael Winfree
Aim: Decades of experimental research have conclusively shown a positive relationship between species richness and ecosystem function. However, authoritative reviews find no consensus on how species loss affects function in natural communities. We analyse experimental and observational data in an identical way and test whether they produce similar results. Location: North America and Europe (experimental communities); global (natural communities). Time period: Experimental communities: 1998–2013; natural communities: 1982–2018. Major taxa studied: Experimental communities: temperate grassland plants;...

Human walking in the real world: interactions between terrain type, gait parameters, and energy expenditure

Daniel Kowalsky, John Rebula, Lauro Ojeda, Peter Adamczyk & Art Kuo
Humans often traverse real-world environments with a variety of surface irregularities and inconsistencies, which can disrupt steady gait and require additional effort. Such effects have, however, scarcely been demonstrated quantitatively, because few laboratory biomechanical measures apply outdoors. Walking can nevertheless be quantified by other means. In particular, the foot’s trajectory in space can be reconstructed from foot-mounted inertial measurement units (IMUs), to yield measures of stride and associated variabilities. But it remains unknown whether such...

Comparative gene expression analysis reveals mechanism of Pinus contorta response to the fungal pathogen Dothistroma septosporum

Mengmeng Lu, Nicolas Feau, Dragana Obreht Vidakovic, Nicholas Ukrainetz, Barbara Wong, Sally Aitken, Richard Hamelin & Sam Yeaman
Many conifers have distributions that span wide ranges in both biotic and abiotic conditions, but the basis of response to biotic stress has received much less attention than response to abiotic stress. In this study, we investigated the gene expression response of lodgepole pine (Pinus contorta) to attack by the fungal pathogen Dothistroma septosporum, which causes Dothistroma needle blight (DNB), a disease that has caused severe climate-related outbreaks in northwestern British Columbia. We inoculated tolerant...

Vape flavorants dull sensory perception and cause hyperactivity in developing zebrafish embryos

Patrick Gauthier, Alison Holloway & Mathilakath Vijayan
E-cigarette use (vaping) during pregnancy has been increasing, and the potential exists for the developing brain in utero to be exposed to chemical constituents in the vape. Vapes come in over 7,000 unique flavors with and without nicotine, and while nicotine is a known neurotoxicant, the effects of vape flavoring alone, in the absence of nicotine, on brain function are not well understood. Here we performed a screen of vape aerosol extracts (VAEs) to determine...

Objective: To evaluate progressive white matter (WM) degeneration in ALS. Methods: Sixty-six patients with ALS and 43 healthy controls were enrolled in a prospective, longitudinal, multicentre study in the Canadian ALS Neuroimaging Consortium (CALSNIC). Participants underwent a harmonized neuroimaging protocol across 4 centres including diffusion tensor imaging (DTI) for assessment of WM integrity. Three visits were accompanied by clinical assessments of disability (ALSFRS-R) and upper motor neuron (UMN) function. Voxel-wise whole brain and quantitative tractwise...

Data from: eDNA concentration, population size structure, and mark-recapture data

Matthew Yates, Dylan Glaser, John Post, Melania Cristescu, Dylan Fraser & Alison Derry
Organism abundance is a critical parameter in ecology, but its estimation is often challenging. Approaches utilizing eDNA to indirectly estimate abundance have recently generated substantial interest. However, preliminary correlations observed between eDNA concentration and abundance in nature are typically moderate in strength with significant unexplained variation. Here we apply a novel approach to integrate allometric scaling coefficients into models of eDNA concentration and organism abundance. We hypothesize that eDNA particle production scales non-linearly with mass,...

Low- versus standard-dose alteplase in acute lacunar ischemic stroke: the ENCHANTED trial - online supplemental

Zien Zhou, Candice Delcourt, Chao Xia, Sohei Yoshimura, Cheryl Carcel, Takako Torii-Yoshimura, Shoujiang You, Alejandra Malavera, Xiaoying Chen, Maree Hackett, Mark Woodward, John Chalmers, Jianrong Xu, Thompson Robinson, Mark Parsons, Andrew Demchuk, Richard Lindley, Grant Mair, Joanna Wardlaw & Craig Anderson
Objective: To determine any differential efficacy and safety of low- versus standard-dose intravenous alteplase for lacunar versus non-lacunar acute ischemic stroke (AIS), we performed post-hoc analyzes from the Enhanced Control of Hypertension and Thrombolysis Stroke Study (ENCHANTED) alteplase dose-arm. Methods: In a cohort of 3297 ENCHANTED participants, we identified those with lacunar or non-lacunar AIS with different levels of confidence (definite/probable/possible) according to pre-specified definitions based on clinical and adjudicated imaging findings. Logistic regression models...

Establishing a current awareness service is a necessity in any discipline, especially in health care. Web 2.0 and social networks have transformed how health care professionals and researchers create knowledge, access information, collaborate, and disseminate research. One of the earliest forms of social media,...

New application of strontium isotopes reveals evidence of limited migratory behaviour in Late Cretaceous hadrosaurs

David Terrill, Charles Henderson & Jason Anderson
Dinosaur migration patterns are very difficult to determine, often relying solely on the geographic distribution of fossils. Unfortunately, it is generally not possible to determine if a fossil taxon’s geographic distribution is the result of migration or simply a wide distribution. Whereas some attempts have been made to use isotopic systems to determine migratory patterns in dinosaurs, these methods have yet to achieve wider usage in the study of dinosaur ecology. Here we have used...

Using Social Media to Create Virtual Interest Groups in Hospital Libraries

Yongtao Lin & Kathryn Ranjit
Social networking has positively impacted the realm of human interactivity. Although libraries have traditionally been viewed as a place for research and information seeking, Web 2.0 technologies, such as blogs and Instant Messaging (IM), are starting to change users’ experiences of current library services. In this study we aim to examine whether the opportunity for enhanced researcher-librarian interaction that Web 2.0 tools provide creates a synergistic experience for health research interest groups. In addition, we...

Muhammad Izhar Shah, Asif Khan, Tahir Ali Akbar, Quazi K Hassan, Asim Jahangir Khan & Ashraf Dewan
The Upper Indus Basin (UIB) is a major source of supplying water to different areas because of snow and glaciers melt and is also enduring the regional impacts of global climate change. The expected changes in temperature, precipitation, and snowmelt could be reasons for further escalation of the problem. Therefore, estimation of hydrological processes is critical for UIB. The objectives of this paper were to estimate the impacts of climate change on water resources and...

Multi-scale habitat assessment of pronghorn migration routes

Andrew Jakes, Nicholas DeCesare, Paul Jones, C Cormack Gates, Scott Story, Sarah Olimb, Kyran Kunkel & Mark Hebblewhite
We studied the habitat selection of pronghorn (Antilocapra americana) during seasonal migration; an important period in an animal’s annual cycle associated with broad-scale movements. We further decompose our understanding of migration habitat itself as the product of both broad- and fine-scale behavioral decisions and take a multi-scale approach to assess pronghorn spring and fall migration across the transboundary Northern Sagebrush Steppe region. We used a hierarchical habitat selection framework to assess a suite of natural...

Paula Gonzalez, Christopher Powell, Warren Wilson, Godwin Olesaningo, Mange Manyama, Heather Jamniczky, Richard Spritz, James Cross, Keneth Lukowiak & Benedikt Hallgrimsson
The reduction of food intake during pregnancy is part of many cultural and religious traditions around the world. The impact of such practices on fetal growth and development are poorly understood. Here, we examined the patterns of diet intake among Maasai pregnant women and assessed their effect on newborn morphometrics. We recruited 141 mother-infant pairs from Ngorongoro Conservation Area (NCA) in Northern Tanzania and quantified dietary intake and changes in maternal diet during pregnancy. We...

Loss of the glucocorticoid receptor causes accelerated reproductive aging in female zebrafish

Erin Faught, Helio Santos & Mathilakath Vijayan
Reproductive decline in mid-adult females isstablished phenotype of the aging process. Stress and the rise in glucocorticoids (GCs) accelerate reproductive aging, but little is known about the mechanisms involved. During stress, GCs activate the glucocorticoid receptor (GR), a ubiquitously expressed, ligand-bound transcription factor, to elicit physiological changes for restoring homeostasis. Here we tested the hypothesis that GC-GR signalling is essential for accelerating reproductive aging. To test this, we used a ubiquitous GR knockout (GRKO) zebrafish,...

Infant cannibalism in wild white-faced capuchin monkeys

Mari Nishikawa, Nuria Ferrero, Saul Cheves, Ronald Lopez, Shoji Kawamura, Linda Fedigan, Amanda Melin & Katharine Jack
Cannibalism has been observed in a variety of animal taxa, however, it is relatively uncommon in primates. Thus we rely heavily on case reports of this behavior to advance our understanding of the contexts under which it occurs. Here we report the first observation of cannibalism in a group of wild white-faced capuchin monkeys (Cebus imitator). The subject was a dead infant, estimated to be 10 days old, and the probable victim of infanticide. Consumption...

Data from: Mechanisms of male-male interference during dispersal of orchid pollen

Lawrence Harder, Shane A. Richards, Jon Ågren & Steven D. Johnson
Siring success of flowering plants depends on the fates of male gametophytes, which compete for access to stigmas, stylar resources and ovules. Although rarely considered, pollen may often compete during dispersal, affecting the processes required for export to stigmas; pollen pickup, transport and deposition. We quantified dispersal interference by tracking bee dispersal of stained Anacamptis morio (Orchidaceae) pollen from individual donor flowers and inferred the affected dispersal mechanisms based on the fit of a process-based...

Bacterial dispersal and drift drive microbiome diversity patterns within a population of feral hindgut fermenters

Mason Stothart, Ruth Greuel, Stefan Gavriliuc, Astrid Henry, Alastair Wilson, Philip McLoughlin & Jocelyn Poissant
Studies of microbiome variation in wildlife often emphasize host physiology and diet as proximate selective pressures acting on host-associated microbiota. In contrast, microbial dispersal and ecological drift are more rarely considered. Using amplicon sequencing, we characterized the bacterial microbiome of adult female (n = 86) Sable Island horses (Nova Scotia, Canada) as part of a detailed individual-based study of this feral population. Using data on sampling date, horse location, age, parental status, and local habitat...
