Invertebrate pollinators are in trouble: particularly documented are declines among bees and butterflies. Interacting stressors include pesticides, pathogens, habitat loss, nonnative species, and climate change. Many governments have strategies to reduce negative pressures on pollinators, but Canada does not despite widespread public interest in pollinator health. This study serves as a needs assessment for science-based policy solutions for wild pollinator conservation in Canada. We designed a Policy Delphi survey technique to identify solutions that experts deem both desirable and feasible. Our secondary aim was to identify research priorities that would inform the implementation of these solutions. Sixty % of the 83 unique solutions were supported and feasible at a high consensus level (10% were “strongly” supported and “definitely” feasible). General themes included improving the Canadian government's approach in assessing pesticide risk to pollinators, curbing pathogen spillover/spillback between managed and wild pollinators, and reducing the reliance of Canadian agricultural systems on pesticides, among others. We discuss solutions in reference to pollinator conservation policies recommended by the broader scientific community and identify policy levers within the context of Canada's highly decentralized approach to biodiversity conservation/management and a political economy that uses high numbers of managed, mostly nonnative bees for pollination services.
无脊椎动物的传粉昆虫遇到了麻烦:尤其是蜜蜂和蝴蝶的数量减少。相互作用的压力源包括杀虫剂、病原体、栖息地丧失、外来物种和气候变化。许多政府都制定了减少传粉昆虫负面压力的策略,但尽管公众对传粉昆虫健康普遍感兴趣,加拿大却没有。这项研究是对加拿大野生传粉昆虫保护基于科学的政策解决方案的需求评估。我们设计了一种政策德尔菲调查技术,以确定专家认为既可取又可行的解决方案。我们的次要目标是确定研究重点,为这些解决方案的实施提供信息。83个独特的解决方案中,60%得到了高度一致的支持和可行(10%得到了“强烈”支持和“绝对”可行)。一般主题包括改进加拿大政府评估杀虫剂对传粉昆虫风险的方法,遏制病原体在管理传粉昆虫和野生传粉昆虫之间的溢出/回流,以及减少加拿大农业系统对杀虫剂的依赖等。我们讨论了参考更广泛的科学界建议的传粉昆虫保护政策的解决方案,并在加拿大高度分散的生物多样性保护/管理方法和使用大量管理蜜蜂(主要是非本地蜜蜂)提供授粉服务的政治经济背景下确定了政策杠杆。

Based on the Mindlin solution, this paper considers the influence of factors such as the non-uniform distribution of additional thrust of the cutter head influenced by lateral earth pressure in shield excavation, the non-uniform distribution of friction of shield shell influenced by soil softening and slurry spreading, and the non-uniform distribution of grouting pressure influenced by slurry spreading on the horizontal displacement of soil. The existing prediction formula is revised and verified by engineering examples. It is found that: affected by the shield construction disturbance force, the horizontal displacement behind the excavation surface is larger than that in front of the excavation surface, and the peak value of the horizontal displacement appears around the tunnel axis; through the verification of engineering case, when calculating the horizontal displacement in front of the excavation surface, the calculation results of both the modified formula and the original formula are in good agreement with the measured values, which can reflect the change trend of the measured horizontal displacement; when calculating the horizontal displacement behind the excavation surface, the calculation result of the existing formula has a great error due to the assumption of uniform distribution of disturbance force, which is different from the law of the measured result; the calculation result of the modified prediction formula is obviously in better agreement with the measured deformation value, and the error is smaller, which is more in line with the engineering reality.
基于Mindlin解,本文考虑了盾构开挖中侧向土压力对刀盘附加推力分布的不均匀性、土体软化和浆液铺展对盾构壳体摩擦分布的不一致性等因素的影响,浆液铺展对土体水平位移的影响以及注浆压力的不均匀分布。对现有的预测公式进行了修正,并通过工程实例进行了验证。研究发现:受盾构施工扰动力影响,开挖面后水平位移大于开挖面前水平位移,水平位移峰值出现在隧道轴线附近;通过工程实例验证,在计算开挖面前水平位移时,修正公式和原公式的计算结果与实测值吻合较好,能够反映实测水平位移的变化趋势;在计算开挖面后水平位移时,由于假定扰动力均匀分布,现有公式的计算结果存在较大误差,与实测结果的规律不同;修正后的预测公式计算结果与实测变形值吻合较好,误差较小,更符合工程实际。

Invasive species are a leading cause of biodiversity loss and species extinctions across ecosystems on a global scale. The historical and ongoing focus on single-species management of invasive species and species at risk contributes to inefficiencies in management strategies that present an obstacle to achieving desired outcomes. A holistic approach that consolidates and maps linkages between the broader collective of invasive species and species at risk in an area provides a more appropriate entry point for issue-based, rather than species-based, management planning. We present a case study of this approach from British Columbia, Canada, which synthesized the identity, mechanisms of impact, mechanisms of spread, and magnitude of impacts across 782 unique pairs of invasive species and federally listed species at risk, based on a literature review of species at risk documentation. The resulting dataset was used to summarize the nature of interactions across species pairs and taxonomic groups to help guide the development of invasive species response strategies that make the best use of limited management resources. As species invasions and extinctions become increasingly interconnected, holistic approaches rooted in cumulative effects assessment and ecosystem-based management can provide a stronger foundation for reducing or mitigating this growing threat.
入侵物种是全球生态系统生物多样性丧失和物种灭绝的主要原因。过去和现在对入侵物种和濒危物种的单物种管理的关注导致管理策略的效率低下,这是实现预期结果的障碍。整合和绘制一个地区更广泛的入侵物种和濒危物种之间的联系的整体方法,为基于问题而不是基于物种的管理规划提供了更合适的切入点。本文以加拿大不列颠哥伦比亚省为例,对782对入侵物种和联邦濒危物种的特征、影响机制、传播机制和影响程度进行了综合分析。结果数据集用于总结物种对和分类群之间相互作用的性质,以帮助指导入侵物种应对策略的制定,从而充分利用有限的管理资源。随着物种入侵和灭绝日益相互关联,基于累积效应评估和基于生态系统的管理的整体方法可以为减少或缓解这一日益严重的威胁提供更坚实的基础。

Although nutrition influences performance, many athletes, including football players, do not meet nutritional requirements for their sport. The objective of this study was to determine the impact of a nutrition intervention combining nutrition education and cooking workshops on nutrition knowledge, intention, and perceived behavioral control in the preparation of healthy meals, dietary intakes, and diet quality in male university football players. Athletes ( n = 23; age: 22 ± 1 year) were randomly assigned to an intervention (2 h/week) ( n = 13) or control group ( n = 10) over three weeks. Questionnaires were completed before (pre), immediately after (post 1), and two months after the intervention (post 2). Dietary intakes and diet quality were evaluated from three web-based 24-h dietary recalls per visit. Mixed linear models for repeated measures with Tukey’s post hoc test were performed to determine the effects of the intervention on all outcomes. There was a group by time interaction for nutrition knowledge ( p = 0.002) that was higher immediately after and two months after the intervention compared to the control group. No differences on other outcomes were observed. Combining nutrition education and cooking workshops improved nutrition knowledge, but did not affect intention and perceived behavioral control in the preparation of healthy meals, dietary intakes, and diet quality in male university football athletes.
尽管营养会影响成绩,但包括足球运动员在内的许多运动员都不符合他们运动的营养要求。本研究的目的是确定结合营养教育和烹饪研讨会的营养干预对男性大学足球运动员在准备健康膳食、饮食摄入量和饮食质量时的营养知识、意图和感知行为控制的影响。运动员(n = 23;年龄:22岁 ± 1年)被随机分配到干预(2小时/周)(n = 13) 或对照组(n = 10) 超过三周。在干预前(前)、干预后(后1)和干预后两个月(后2)完成问卷调查。从每次访问的三次基于网络的24小时饮食回忆中评估饮食摄入量和饮食质量。重复测量的混合线性模型与Tukey的事后检验相结合,以确定干预对所有结果的影响。在营养知识方面存在一组按时间的交互作用(p = 0.002),这与对照组相比在干预后立即和两个月后更高。未观察到其他结果的差异。营养教育和烹饪讲习班的结合提高了男性大学足球运动员的营养知识,但不影响他们在准备健康膳食、饮食摄入量和饮食质量方面的意图和感知行为控制。

Ethnobiological studies on folk, common, or popular names that fishers use to identify fish can help improve fisheries monitoring and collaborations between fishers and researchers. This study investigates fishers’ knowledge (recognition, naming, and habitat use) on 115 and 119 fish species, respectively, in the Negro and Tapajos Rivers, two megadiverse rivers in the Brazilian Amazon, and investigates the relationship between such knowledge and fish importance to fisheries, fish abundance, and fish size. We also compared fishers’ perceptions on fisheries and fish abundance with literature data on fish harvests and fish sampling. We interviewed 16 fishers in 16 communities (one fisher per community, 8 communities along each river). These fishers recognized an average of 91 ± 10.4 species in the Negro River and 115 ± 7.2 species in the Tapajos River, but all fishers recognized 114 species in Negro and all species in Tapajos. The fishers’ knowledge of fish species was positively related to fishers’ perceptions on fish abundance, size, and importance to fisheries in the Negro, but only positively related to fish size in the Tapajos. Our results highlight the usefulness of fishers’ knowledge to providing data on use and cultural relevance of fish species in high diversity aquatic ecosystems.
对渔民用来识别鱼类的民间、常见或流行名称进行民族生物学研究,有助于改善渔业监测以及渔民和研究人员之间的合作。本研究调查了巴西亚马逊地区两条大型河流Negro河和Tapajos河中115种和119种鱼类的渔民知识(识别、命名和栖息地使用),并调查了这些知识与鱼类对渔业的重要性、鱼类丰度和鱼类大小之间的关系。我们还将渔民对渔业和鱼类丰度的看法与鱼类收获和鱼类采样的文献数据进行了比较。我们采访了16个社区的16名渔民(每个社区一名渔民,每条河沿岸8个社区)。这些渔民平均识别出91 ± 内格罗河10.4种,115种 ± Tapajos河有7.2个物种,但所有渔民都在Negro发现了114个物种,在Tapajos发现了所有物种。渔民对鱼类物种的了解与渔民对内格罗河鱼类丰度、大小和对渔业重要性的看法呈正相关,但仅与塔帕霍斯的鱼类大小呈正相关。我们的研究结果强调了渔民的知识对提供关于鱼类在高度多样性水生生态系统中的使用和文化相关性的数据的有用性。

Traditional food systems based on harvest from the local environment are fundamental to the well-being of many communities, but their security is challenged by rapid socio-ecological change. We synthesized literature and data describing how a fundamental form of biodiversity, animal body size, contributes to the security of traditional food systems through relationships with species availability, accessibility, adequacy, and use. We found larger vertebrate species were more available, accessible, and used on a per kilogram basis, particularly for mammals. Conversely, larger species were no more or less adequate from a combined nutritional, health, and cultural perspective. Larger species represented more biomass, and this biomass required less time to harvest, with greater but more variable mean caloric returns over time. Smaller species provided more consistent caloric returns and were harvested during documented shortages of prey. This reliance on species with a range of body sizes is consistent with optimal foraging theory and the evolutionary value of flexibility, and highlights the importance of a biodiverse pool of species for traditional food security in times of change. Our synthesis of published literature and data highlights the many socio-ecological correlates of species size and how these relate to the security of traditional food systems.
基于当地环境收获的传统粮食系统对许多社区的福祉至关重要,但其安全受到快速社会生态变化的挑战。我们综合了文献和数据,描述了生物多样性的一种基本形式,即动物体型,如何通过与物种可用性、可及性、充分性和使用的关系,为传统粮食系统的安全做出贡献。我们发现,以每公斤为单位,更大的脊椎动物物种更容易获得、获得和使用,尤其是哺乳动物。相反,从营养、健康和文化的角度来看,较大的物种或多或少都不够。较大的物种代表着更多的生物量,这种生物量需要更少的收获时间,随着时间的推移,平均热量回报率更大,但变化更大。较小的物种提供了更一致的热量回报,并在记录在案的猎物短缺期间被捕获。这种对不同体型物种的依赖符合最佳觅食理论和灵活性的进化价值,并突出了生物多样性物种库在变化时期对传统粮食安全的重要性。我们对已发表的文献和数据的综合强调了物种大小的许多社会生态相关性,以及这些相关性如何与传统粮食系统的安全相关。

In response to colonial research paradigms that have subjugated Indigenous Peoples, knowledges, lands, and waters, Indigenous research methodologies have emerged to center Indigenous visions and voices in research practice. Here, we employ such methodologies to improve collective understanding of the state and future of wild Pacific salmon ( Oncorhynchus spp.) and fish–people–place relationships across British Columbia’s three largest salmon-producing rivers: the Fraser, Skeena, and Nass. Through partnerships with 18 communities of “Salmon People” and semi-structured interviews with 48 knowledge holders (i.e., Elders), we learned that, on average, Elders spent more than half of a century actively engaged in salmon fishing and processing. Modern salmon catches are reported to be approximately one-sixth of what they were estimated to be five to seven decades ago, and the top five threats to salmon identified by Elders included ( i) aquaculture, ( ii) climate change, ( iii) contaminants, ( iv) industrial development, and ( v) infectious diseases. Threat priorities varied regionally, reflecting distinct lived experiences and regional variation in the prevalence and impact of different threats. Elders perceived threats to salmon equally as threats to aquatic health and human well-being, with evidence that the relationships between people and water, and salmon and people, are being profoundly transformed.
为了应对征服土著人民、知识、土地和水域的殖民研究范式,土著研究方法已经出现,在研究实践中集中了土著的视野和声音。在这里,我们采用这样的方法来提高对野生太平洋鲑鱼(Oncorhynchus spp.)的现状和未来的集体理解,以及跨越不列颠哥伦比亚省三条最大的鲑鱼生产河流:弗雷泽河、斯基纳河和纳斯河的鱼-人-地关系。通过与18个“鲑鱼人”社区的合作,以及对48位知识持有者(即长者)的半结构化访谈,我们了解到,长者平均花了半个多世纪的时间积极参与鲑鱼捕捞和加工。据报告,现代鲑鱼的捕获量约为50至70年前估计的六分之一,Elders确定的鲑鱼面临的五大威胁包括:(一)水产养殖、(二)气候变化、(三)污染物、(四)工业发展和(五)传染病。威胁优先事项因区域而异,反映了不同的生活经历和不同威胁的流行程度和影响的区域差异。长老们认为对鲑鱼的威胁同样是对水生健康和人类福祉的威胁,有证据表明,人与水、鲑鱼与人之间的关系正在发生深刻的变化。

Modern salmon catches are reported to be approximately one-sixth of what they were estimated to be five to seven decades ago, and the top five threats to salmon identified by Elders included ( i) aquaculture, ( ii) climate change, ( iii) contaminants, ( iv) industrial development, and ( v) infectious diseases. Threat priorities varied regionally, reflecting distinct lived experiences and regional variation in the prevalence and impact of different threats. Elders perceived threats to salmon equally as threats to aquatic health and human well-being, with evidence that the relationships between people and water, and salmon and people, are being profoundly transformed.","PeriodicalId":48511,"journal":{"name":"Facets","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47588351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a growing interest in training on responsible conduct of research (RCR). The availability and range of such training materials, for a diversity of audiences and addressing a diversity of RCR related topics, is growing too. This is of great help to all who are looking for materials to set up their RCR training, but how can one select what topics to include within the often-limited time available for training? In this paper we propose a step-by-step approach to set the agenda for RCR training, using the target audience as a narrative guide. The process consists of six steps: (1) mapping the needs and translating them into learning objectives; (2) prioritizing, selecting, and combining objectives and themes; (3) demarcation of the training; (4) completion of the program; (5) development or adaptation of training materials; and (6) pilot and evaluation. The development process of a training program for researchers in Dutch Universities of Applied Sciences is used as an example to illustrate the step-by-step process.
人们对负责任的研究行为培训越来越感兴趣。这类培训材料的可获得性和范围也在增加,面向不同的受众,涉及不同的RCR相关主题。这对所有正在寻找材料来设置RCR培训的人都有很大帮助,但如何在通常有限的培训时间内选择要包括哪些主题?在本文中,我们提出了一种循序渐进的方法来设定RCR培训的议程,使用目标受众作为叙事指南。该过程包括六个步骤:(1)绘制需求图并将其转化为学习目标;(2) 对目标和主题进行优先排序、选择和组合;(3) 训练的界限;(4) 项目完成情况;(5) 编写或改编培训材料;以及(6)试点和评估。以荷兰应用科学大学研究人员培训计划的制定过程为例,说明了循序渐进的过程。

Given its extensive volume and reach, social media has the potential to widely spread conservation messaging and be a powerful tool to mobilize social change for conserving biodiversity. We synthesized gray and primary academic literature to investigate the effects of social media on wildlife conservation, revealing several overarching benefits and risks. We found that social media can increase pro-conservation behaviours among the public, increase conservation funding, and incite policy changes. Conversely, social media can contribute to species exploitation and illegal trade, cause unprecedented increases in tourism in protected areas, and perpetuate anti-conservation behaviours via misinformation. In most cases, we found that content sharing on social media did not result in a detectable impact on conservation; in this paper, however, we focus on providing examples where conservation impact was achieved. We relate these positive and negative outcomes of social media to psychological phenomena that may influence conservation efforts and discuss limitations of our findings. We conclude with recommendations of best practices to social media administrators, public social media users, nongovernmental organizations, and governing agencies to minimize conservation risks while maximizing beneficial outcomes. By improving messaging, policing online misconduct, and providing guidance for action, social media can help achieve wildlife conservation goals.
鉴于其广泛的数量和影响范围,社交媒体有可能广泛传播保护信息,并成为动员社会变革以保护生物多样性的有力工具。我们综合了灰色和初级学术文献,调查了社交媒体对野生动物保护的影响,揭示了几个总体的好处和风险。我们发现,社交媒体可以增加公众的保护行为,增加保护资金,并引发政策变化。相反,社交媒体可能助长物种开发和非法贸易,导致保护区旅游业空前增长,并通过错误信息使反保护行为持续下去。在大多数情况下,我们发现社交媒体上的内容共享不会对保护产生可检测的影响;然而,在本文中,我们的重点是提供实现保护影响的例子。我们将社交媒体的这些积极和消极结果与可能影响保护工作的心理现象联系起来,并讨论了我们研究结果的局限性。最后,我们向社交媒体管理员、公共社交媒体用户、非政府组织和管理机构提出了最佳实践建议,以最大限度地降低保护风险,同时最大化有益结果。通过改善信息传递,监管网络不当行为,并为行动提供指导,社交媒体可以帮助实现野生动物保护目标。

Resource development and climate change are increasing concerns regarding safe water for Indigenous people in Canada. A research study was completed to characterize the consumption of water and beverages prepared with water and identify the perception of water consumption in Indigenous communities from the Northwest Territories and Yukon, Canada. As part of a larger research program, data for this study were available from a 24-hour recall dietary survey ( n = 162), a health messages survey ( n = 150), and an exposure factor survey ( n = 63). A focus group was conducted with Elders in an on-the-land camp setting. The consumption of water-based beverages in winter was 0.9 L/day on average, mainly consisting of tea and coffee. Of the 81% of respondents who reported consuming water-based beverages in the previous 24 hours of the survey, 33% drank more bottled water than tap water. About 2% of respondents consumed water from the land (during the winter season). Chlorine smell was the main limiting factor reported to the consumption of tap water. Results from the focus group indicated that Indigenous knowledge might impact both the perception and consumption of water. These findings aim to support public health efforts to enable people to make water their drink of choice.
资源开发和气候变化日益引起人们对加拿大土著人民安全用水的关注。完成了一项研究,以确定西北地区和加拿大育空地区土著社区的水和用水饮料的消费特征,并确定对水消费的看法。作为一个更大的研究项目的一部分,本研究的数据来自24小时回忆性饮食调查(n = 162)、健康信息调查(n = 150)和暴露因素调查(n = 63)。一个焦点小组与长老在陆地营地设置。冬季水基饮料的平均消费量为0.9 L/d,主要以茶和咖啡为主。81%的受访者表示在调查的前24小时内喝过水饮料,其中33%的人喝的瓶装水比自来水多。约2%的答复者(在冬季)从陆地上取水。氯味是影响自来水消费的主要制约因素。焦点小组的结果表明,土著知识可能会影响对水的感知和消费。这些发现旨在支持公共卫生努力,使人们能够选择水作为他们的饮料。
