    • Lifestyle decisions and climate mitigation: current action and behavioural intent of youth

      Pickering, Gary J.; Schoen, Kaylee; Botta, Marta (Springer Science and Business Media LLC, 2021-07-26)
      Youth carry the burden of a climate crisis not of their making, yet their accumulative lifestyle decisions will help determine the severity of future climate impacts. We surveyed 17–18 year old’s (N=487) to establish their action stages for nine behaviours that vary in efficacy of greenhouse gas emission (GGE) reduction and the explanatory role of climate change (CC) knowledge, sociodemographic and belief factors. Acceptance of CC and its anthropogenic origins was high. However, the behaviours with the greatest potential for GGE savings (have no children/one less child, no car or first/next car will be electric, eat less meat) have the lowest uptake. Descriptive normative beliefs predicted intent to adopt all high-impact actions, while environmental locus of control, CC scepticism, knowledge of the relative efficacy of actions, religiosity and age were predictive of action stage for several mitigation behaviours (multinomial logistic regression). These findings inform policy and communication interventions that seek to mobilise youth in the global climate crisis response
    • Living in Two Cultures: Chinese Canadians’ Perspectives on Health

      Lu, Chunlei; McGinn, Michelle K.; Xu, Xiaojian; Sylvestre, John (Springer Science and Business Media LLC, 2016-03-21)
      OBJECTIVES: Chinese people have distinctive perspectives on health and illness that are largely unrecognized in Western society. The purpose of this descriptive study was to develop a profile of Chinese immigrants’ beliefs and practices related to diet, mental and social health, and sexual health. METHODS: A quantitative survey with descriptive and correlational analyses was employed to examine 100 first-generation Chinese immigrants living in four urban centres across Canada (Vancouver, Toronto, Halifax, and St. Catharines). RESULTS: Although most Chinese immigrants preferred a Chinese diet, where they resided affected the groceries they bought and the meals they ate. Almost all participants reported their mental health was important to them and most felt comfortable discussing mental health issues with others. However, only a third would see a psychiatrist if they believed they had a mental health problem. Most participants believed social relationships were important for their health. Only a small number of participants, however, preferred making friends with mainstream Caucasian Canadians. More men than women believed sexuality contributed to health and were comfortable talking about sexual health. CONCLUSION: Chinese immigrants should be encouraged to be more engaged in the larger community in order to fully integrate themselves into Canadian society while still being encouraged to retain their healthy practices. These findings may help educators and practitioners enhance their understandings of Chinese immigrants’ perspectives on health and develop culturally competent education and services in health care and health promotion.
    • A Long-Term Study on Massasaugas (Sistrurus catenatus) Inhabiting a Partially Mined Peatland: A Standardized Method to Characterize Snake Overwintering Habitat

      Yagi, Anne R.; Planck, R. Jon; Yagi, Katharine T.; Tattersall, Glenn J. (Society for the Study of Amphibians and Reptiles, 2020-05-15)
      Temperate snakes occupy overwintering sites for most of their annual life cycle. Microhabitat characteristics of the hibernaculum are largely undescribed, yet are paramount in ensuring snake overwintering survival. We hypothesized that snakes survive hibernation within a vertical subterranean space that we termed a “life zone” (LZ), that is aerobic and flood and frost free throughout winter. We studied an isolated, endangered population of Massasaugas (Sistrurus catenatus) inhabiting an anthropogenically altered peatland and monitored the subterranean habitat during a period of environmental stochasticity. Initial radio telemetry confirmed that snakes moved between altered and natural habitats during the active season and showed hibernation-site fidelity to either habitat. We used a grid of groundwater wells and frost tubes installed in each hibernation area to measure LZ characteristics over 11 consecutive winters. The LZ within the impacted area was periodically reduced to zero during a flood–freeze cycle, but the LZ in the natural area was maintained. Model selection analysis revealed that soil depth and flood status best predicted LZ size. Thermal buffering and groundwater dissolved oxygen increased with LZ size, and annual Massasauga encounters were significantly correlated with LZ size. This analysis suggests a population decline occurred when LZ size was reduced by flooding. Our data give support to the importance and maintenance of an LZ for successful snake hibernation. Our methods apply to subterranean hibernation habitats that are at risk of environmental stochasticity, causing flooding, freezing, or hypoxia.
    • A Low-Therapeutic Dose of Lithium Inhibits GSK3 and Enhances Myoblast Fusion in C2C12 Cells

      Kurgan, Nigel; Whitley, Kennedy C; Maddalena, Lucas A; Moradi, Fereshteh; Stoikos, Joshua; Hamstra, Sophie I; Rubie, Elizabeth A; Kumar, Megha; Roy, Brian D; Woodgett, James R; et al. (MDPI, 2019)
      Glycogen synthase kinase 3 (GSK3) slows myogenic differentiation and myoblast fusion partly by inhibiting the Wnt/β-catenin signaling pathway. Lithium, a common medication for bipolar disorder, inhibits GSK3 via Mg+ competition and increased Ser21 (GSK3α) or Ser9 (GSK3β) phosphorylation, leading to enhanced myoblast fusion and myogenic differentiation. However, previous studies demonstrating the effect of lithium on GSK3 have used concentrations up to 10 mM, which greatly exceeds concentrations measured in the serum of patients being treated for bipolar disorder (0.5–1.2 mM). Here, we determined whether a low-therapeutic (0.5 mM) dose of lithium could promote myoblast fusion and myogenic differentiation in C2C12 cells. C2C12 myotubes differentiated for three days in media containing 0.5 mM lithium chloride (LiCl) had significantly higher GSK3β (ser9) and GSK3α (ser21) phosphorylation compared with control myotubes differentiated in the same media without LiCl (+2–2.5 fold, p < 0.05), a result associated with an increase in total β-catenin. To further demonstrate that 0.5 mM LiCl inhibited GSK3 activity, we also developed a novel GSK3-specific activity assay. Using this enzyme-linked spectrophotometric assay, we showed that 0.5 mM LiCl-treated myotubes had significantly reduced GSK3 activity (−86%, p < 0.001). Correspondingly, 0.5 mM LiCl treated myotubes had a higher myoblast fusion index compared with control (p < 0.001) and significantly higher levels of markers of myogenesis (myogenin, +3-fold, p < 0.001) and myogenic differentiation (myosin heavy chain, +10-fold, p < 0.001). These results indicate that a low-therapeutic dose of LiCl is sufficient to promote myoblast fusion and myogenic differentiation in muscle cells, which has implications for the treatment of several myopathic conditions
    • Managing Water and Watersheds for Co-benefits: Human well-being and ecosystem services in the Credit River Watershed

      Bunch, Martin; Morrison, Karen (2015)
      The importance of ecosystem services (ES) to human well-being, and of management of water and other watershed resources in maintaining such services, is not commonly understood by the general public, and not well-enough articulated by environmental management and governance organizations. Beneficiaries of such services are often unaware of the nature of their dependence upon supporting ecosystems. This is particularly true in urbanized watersheds, to the point where researchers discuss “nature deficit disorder” as an aspect of this disconnection. Watershed management organizations are aware of such benefits to watershed residents, but they very rarely track and report measures of human well-being to demonstrate the efficacy of their work. In managing water and watersheds such as the Credit River watershed, managers and policy makers deal with complex coupled human and natural systems that are characterized by irreducible uncertainty, multiple stakeholders, relationships that are often multiple, diffuse and interacting, and that are affected by strong driving forces such as urbanization and climate change. In such problematic situations the positioning of interventions on the landscape is an area of increased interest.
    • The Marzamemi Maritime Heritage Project: from the seabed to the museum and beyond

      Leidwanger, Justin; Greene, Elizabeth S.; Repola, Leopoldo; Sgroi, Farbizio (2021)
      The Marzamemi Maritime Heritage Project is a collaborative excavation, survey and heritage management initiative along south-east Sicily focusing on long-term structures of human interaction from prehistory through classical antiquity and up to the present. Situated between west and east, south and north, this corner of the island provides a vantage point for varied material manifestations of connectivity across millennia. Between 2013 and 2019, the project launched new investigations of the 6th-century AD Marzamemi 2 wreck (also known as the ‘church wreck’), which was originally explored by Gerhard Kapitän in the 1960s. The vessel sank while carrying perhaps 100 tonnes of prefabricated architectural elements – column shafts, capitals, bases and other decorative furnishings – in part intended to decorate a church. The project simultaneously aims to re-embed this and other local maritime heritage within the broader context of countless journeys along this shore. Through survey of historic maritime material culture alongside innovative museum development and immersive exhibits, we juxtapose ancient ships with still older and more recent heritage at the heart of this ‘Middle Sea’. In doing so, we aim to broaden 21st-century maritime archaeology in a way that leverages the past for new and challenging engagement with contemporary mobility and human connectivity.
