Conservation issues are often complicated by sociopolitical controversies that reflect competing philosophies and values regarding natural systems, animals, and people. Effective conservation outcomes require managers to engage myriad influences (social, cultural, political, and economic, as well as ecological). The contribution of conservation scientists who generate the information on which solutions rely is constrained if they are unable to acknowledge how personal values and disciplinary paradigms influence their research and conclusions. Conservation challenges involving controversial species provide an opportunity to reflect on the paradigms and value systems that underpin the discipline and practice of conservation science. Recent analyses highlight the ongoing reliance on normative values in conservation. We frame our discussion around controversies over feral horses (Equus ferus caballus) in the Canadian West and New Zealand and suggest that a lack of transparency and reflexivity regarding normative values continues to prevent conservation practitioners from finding resilient conservation solutions. We suggest that growing scrutiny and backlash to many normative conservation objectives necessitates formal reflexivity methods in conservation biology research, similar to those required of researchers in social science disciplines. Moreover, given that much conservation research and action continues to prioritize Western normative values regarding nature and conservation, we suggest that adopting reflexive methods more broadly is an important step toward more socially just research and practice. Formalizing such methods and requiring reflexivity in research will not only encourage reflection on how personal and disciplinary value systems influence conservation work but could more effectively engage people with diverse perspectives and values in conservation and encourage more novel and resilient conservation outcomes, particularly when dealing with controversial species., (© 2021 Society for Conservation Biology.)

Hand hygiene is a long-standing concern in the health sciences literature, but its emergence as a public health issue in the news is a more recent development. Drawing on Alan Hunt’s work on moral regulation and responsibilization, this article analyses 30 years of Canadian newspaper coverage of hand hygiene. Concerns associated with hand hygiene and trends in coverage were identified in a sample of 518 articles, published between 1986 and 2015. Although the Severe Acute Respiratory Syndrome (SARS) and H1N1 influenza epidemics emerged as important triggers, healthcare-associated infection (HAI) was the dominant trigger for hand hygiene coverage. The articles tend to present hand hygiene as a unidimensional approach to infection control. They tend to responsibilize individuals-first members of the general public, then healthcare providers and increasingly patients-for managing the risk of infection, rather than focus upon social, cultural, political and economic factors that would promote a more broad-based and structural response to HAI.

Programs and reforms to prevent healthcare-associated infections encounter structural barriers that affect their adoption and effective implementation. This article is based on interviews with 55 frontline healthcare providers, infection control and quality experts, and policymakers from 2010–2013 primarily in Vancouver, Canada. This article reports the perceptions of participants regarding the consequences that structural barriers, including physical structure, staffing levels, education, policy variations, and authority, have on their ability to prevent healthcare-associated infections. The findings suggest the need to shift more funding to preventative measures, such as more infection-prevention professionals, higher participation in quality programs and increased availability of isolation rooms to reduce healthcare-associated infections. In addition, leadership and resources are needed to expand (1) mandatory annual infection prevention education sessions to all hospital staff with point of care follow up, and (2) standardised, evidence-based antimicrobial stewardship clinical practice guidelines and policies.

We assess risks posed by oak wilt—a disease caused by the fungal pathogen Bretziella fagacearum. Though not currently found in Canada, our distribution models indicate that suitable climate conditions currently occur in southern Ontario for B. fagacearum and two of its main insect dispersal vectors, Colopterus truncatus and Carpophilus sayi. Climate habitat for these species is projected to expand northward under climate change, with much of the oak range in eastern Canada becoming climatically suitable within the next two decades. Potential costs for the removal and replacement of oak street trees ranged from CDN$266 to $420 million, with variation related to uncertainty in costs, rate of tree replacement, and city-level estimates of oak street tree density. The value of standing oak timber in eastern Canada was estimated at CDN$126 million using provincial stumpage fees and as a CDN$24 million annual contribution to national Gross Domestic Product (GDP) when calculated using a combination of economic and forestry product statistics. These values can help inform the scale of eradication and/or management efforts in the event of future oak wilt introductions. [ABSTRACT FROM AUTHOR]

Nest survival is most limited by nest predation, which often is increased by anthropogenic causes including habitat fragmentation, mesopredator release and predator subsidies. In mallards and other upland-nesting duck species in the North American prairies, the rate of nest survival is the vital rate most influential to population dynamics, with 15%–20% survival required for maintenance of stable populations. Predator removal during the nesting season has increased duck nest survival on township-sized (9324 ha) areas of agricultural ecosystems in eastern locations of the prairie pothole region (PPR). However, predator removal has not been evaluated in western parkland habitats of the PPR where three-dimensional structure of vegetation is considerably greater. During 2015–2017, we evaluated nest survival on control and predator-removal plots at two study areas in the parklands of central Alberta, Canada. In the second year of the study, we transposed predator removal to control for habitat effects. Estimates of 34-day nest survival did not significantly differ between trapped ( x ¯ = 20.9%, 95% CI = 13.2%–33.7%) and control ( x ¯ = 17.8%, 95% CI = 10.5%–30.0%) plots in any year. We do not recommend predator removal be continued in Alberta parklands due to its ineffectiveness at improving duck nest survival at the local scale. [ABSTRACT FROM AUTHOR]
