Associations between mental health disorder symptoms and cardiac function among Royal Canadian Mounted police cadets during the Cadet training program
(Elsevier BV, 2026-01) Carleton, R.N.; Teckchandani, T.A.; Neary, J.P.; Samayoa, J.E.; Khoury, J.M.B.; Maguire, K.Q.; Krätzig, G.P.; Asmundson, G.J.G.
Cardiac regulation is a complex process involving interplay between neuroautonomic and neuroendocrine sys- tems. Occupations frequently exposed to potentially psychologically traumatic events (PPTEs; e.g., fire or ex- plosion, natural disaster, sexual assault), such as the Royal Canadian Mounted Police (RCMP), report elevated Posttraumatic Stress Injuries (PTSIs; e.g., Posttraumatic Stress Disorder [PTSD], Major Depressive Disorder [MDD], Generalized Anxiety Disorder [GAD], Social Anxiety Disorder [SAD], Alcohol Use Disorder [AUD]). Neurohormonal pathway dysfunction is associated with mental health disorder symptoms, but meaningful evaluations remain methodologically challenging, especially in high-stress occupations (e.g., police). The current study tested for associations among cardiac function and mental health disorder symptoms. Participants included RCMP cadets (n = 81; 28.4 % women) who completed self-report symptom measures at pre-training and pre- deployment of PTSD, MDD, GAD, SAD, and AUD. To test for longitudinal associations between cardiac func- tion and mental health disorder symptoms, a series of paired-samples t-tests and bootstrapped partial correlations controlling for age and sex were conducted. The current study evidenced positive associations between changes in the myocardial performance index, the diastolic performance index, and isovolumic relaxation time compa- rable in magnitude to changes in MDD, GAD, and SAD symptoms (but not AUD symptoms), as well as between IVRT and PTSD symptoms, and rapid ejection time and GAD symptoms. The associations provide rationale for integrating cardiac rehabilitation exercise guidelines into occupational fitness programs as a method to mitigate the cumulative impact of occupational stressors

An assessment of mental health challenges and occupational stressors among public safety personnel senior leadership
(Elsevier BV, 2026-02) Carleton, R.N.; Teckchandani, T.A.; MacPhee, R.S.; Camp II, R.; Nisbet, J.
Substantial evidence indicates frontline public safety personnel (PSP), including, but not limited to firefighters, paramedics, and police, report significantly more occupational stressors, mental health challenges, and suicidal behaviours than the general population, largely attributed to their public service. In contrast, there is a paucity of research assessing the mental health of PSP serving in senior leadership roles (i.e., Chiefs, Directors, or Deputy Chiefs). The current study assessed prevalence proportions of occupational stressors, mental health challenges, and suicidal behaviours among paramedics and police serving in senior leadership relative to PSP in other roles within the organization. Participants included Canadian paramedics and police officers (n = 3717). Independent samples t-tests were conducted to assess for differences in mean mental health disorder symptom and occupational stressor scores between professional roles (i.e., PSP senior leadership vs other serving PSP) within PSP sectors. Bootstrapped logistic regression models tested for differences in relative risk for screening positive for mental health disorders and suicidal behaviours, and a series of bootstrapped partial point biserial correlations tested for associations between individual occupational stressors and screening positive for any mental health disorder. Despite differences in occupational demands, responsibilities, individual organizational, and operational stressors between the roles, there were very few statistically significant differences between serving PSP and their senior leadership. PSP senior leadership may face specific barriers to accessing care as a function of their highly visible positions and relatively limited options for peer support. Additional research is needed to understand the contemporary mental health and wellbeing needs of PSP senior leadership.

The hidden biodiversity knowledge split in biological collections
(The Royal Society, 2025-11) Nakamura, Gabriel; Stabile, Bruno Henrique Mioto; Frateles, Livia Estéfane Fernandes; Araujo, Matheus Lima; Neuhaus, Emanuel Bruno; Marinho, Manoela Maria Ferreira; de Souza Leite, Melina; Richter, Aline; Ding, Liuyong; Freitas, Tiago Magalhães da Silva; Soares, Bruno; Graça, Weferson Júnio da; Moura, Mario R.; Diniz-Filho, José Alexandre Felizola
Ecological and evolutionary processes generate biodiversity, yet how biodiversity data are organized and shared globally can shape our understanding of these processes. We show that name-bearing type specimens—the primary reference for species identity—of all freshwater and brackish fish species are predominantly housed in Global North museums, disconnected from their countries of origin. This geographical divide creates a ‘knowledge split’ with consequences for biodiversity science, particularly in the Global South, where researchers face barriers in studying native species’ name bearers housed abroad. Meanwhile, Global North collections remain flooded with non-native name bearers. We relate this imbalance to historical and socioeconomic factors, which ultimately restrict access to critical taxonomic reference materials and hinder global species documentation. To address this disparity, we call for international initiatives to promote fairer access to biological knowledge, including specimen repatriation, improved accessibility protocols for researchers in countries where specimens originated and inclusive research partnerships.

Shattering the Silence
(Faculty of Education, University of Regina, 2017-07) Niessen, Shuana
The ebook Shattering the Silence: The Hidden History of Indian Residential Schools in Saskatchewan is intended to support teachers as they prepare to teach about the legacy of Indian residential schools in Saskatchewan. The resource is accompanied by a website with supplementary resources. Each section of the e-book contains Saskatchewan Curricular connections. The book profiles each of the Saskatchewan-located residential schools, drawing on historical documents, archived and current news reports, local history books, and the reports that came out of the Truth and Reconciliation Commission. As stated by the Canada School Libraries, "It contains a wealth of resources for adults, youth, children and students, links to professional development, curricular connections and inquiry starters. Although focused on Saskatchewan, resources and understandings presented are universal.”

Hydrologic Variability Drives Differential Methane Dynamics in Agricultural Reservoirs of the Northern Great Plains
(American Geophysical Union (AGU), 2026-01-31) Rimas, Ryan; Webb, Jackie; Finlay, Kerri
Climate variability can regulate aquatic methane fluxes as increasing temperatures can elevate microbial metabolic rates, including methanogenesis. It is less well known how climate‐induced variability in seasonal precipitation and runoff might affect methane concentrations and fluxes in aquatic ecosystems. Here, we measured seasonal methane concentrations and calculated diffusive fluxes from 20 agricultural reservoirs in the northern Great Plains in contrasting wet and dry summers. Relative to the dry year, water column depths increased 65% (from 1.7 to 2.6 m) in the wet year and was associated with stronger stratification and increased anoxia at depth. Solute concentrations also declined during the wet year, with sulfate concentrations less than half that observed in the dry year (645 mg SO42 L 1 vs. 1620 mg SO42 L 1). Together, the more profound anoxia combined with lower sulfate concentrations resulted in significantly higher hypolimnetic CH4 concentrations in the wet year (40.3 μM) compared with the dry year (18.1 μM), particularly in August (30‐fold higher). Despite these patterns, surface CH4 concentrations and estimated diffusive emissions did not significantly increase in wet summers (1.13 μM and 2.31 mmol m 2 yr 1) relative to dry summers (3.78 μM and 5.71 mmol m 2 yr 1), likely owing to offsetting mechanisms of increased CH4 storage and oxidation through the deeper water column. Climate‐driven changes in precipitation and runoff are expected to modify the physical factors controlling methanogenesis and methanotrophy. Our findings show corresponding minimal effects on diffusive fluxes of methane, but future studies should also address ebullition and seasonal turnover to capture the full CH4 budget of inland waters.
