“…The loss of cold‐stenothermic species and associated important functions is therefore of special conservation concern (Culp et al . ). Although we could not assign thermal preferences to 42% of the taxa, but for those that we could, more than 50% tolerated warmer conditions and only 3% were cold stenothermic and occurred only in subarctic lakes.…”

“…Awareness of periled northern fresh waters has resulted in calls of internationally standardized biomonitoring efforts to assess and mitigate the impacts of global change on arctic fresh waters and their locally and globally coupled societies (Culp et al . ). In this study, we analyse unique long‐term biomonitoring data to evaluate the vulnerability of subarctic Swedish lakes to changing environmental conditions during the last two decades.…”

Summary1. Ecosystems at high altitudes and latitudes are expected to be particularly vulnerable to the effects of global change. We assessed the responses of littoral invertebrate communities to changing abiotic conditions in subarctic Swedish lakes with long-term data and compared the responses of subarctic lakes with those of more southern, hemiboreal lakes. 2. We used a complex systems approach, based on multivariate time-series modelling, and identified dominant and distinct temporal frequencies in the data; that is, we tracked community change at distinct temporal scales. We determined the distribution of functional feeding groups of invertebrates within and across temporal scales. Within and cross-scale distributions of functions have been considered to confer resilience to ecosystems, despite changing environmental conditions. 3. Two patterns of temporal change within the invertebrate communities were identified that were consistent across the lakes. The first pattern was one of monotonic change associated with changing abiotic lake conditions. The second was one of showing fluctuation patterns largely unrelated to gradual environmental change. Thus, two dominant and distinct temporal frequencies (temporal scales) were present in all lakes analysed. 4. Although the contribution of individual feeding groups varied between subarctic and hemiboreal lakes, they shared overall similar functional attributes (richness, evenness, diversity) and redundancies of functions within and between the observed temporal scales. This highlights similar resilience characteristics in subarctic and hemiboreal lakes. 5. Synthesis and applications. The effects of global change can be particularly strong at a single scale in ecosystems. Over time, this can cause monotonic change in communities and eventually lead to a loss of important ecosystem services upon reaching a critical threshold. Dynamics at other spatial or temporal scales can be unrelated to environmental change. The relative 'intactness' of these scales that are unaffected by global change and the persistence of functions at those scales may safeguard the whole system from the potential loss of functions at the scale at which global change impacts can be substantial. Thus, an understanding of scale-specific processes provides managers with a realistic assessment of vulnerabilities and the relative resilience of ecosystems to environmental change. Explicit consideration of 'intact' and 'affected' scales in analyses of global change impacts provides opportunities to tailor more specific management plans.

“…The ecological effects of climate change in arctic and subarctic streams and rivers are a factor of a change in both baseline conditions and extreme events (e.g. Culp et al, 2012). For example, an overall warming trend may cause northward species migration or extinction if benign habitats become unavailable (Hof, Jansson & Nilsson, 2012), and this may affect how the ecological community responds to an extreme event.…”

Summary We review the predicted changes in extreme events following climate change in flowing waters in arctic and subarctic regions. These regions are characterised by tundra or taiga ecosystems in either erosional or depositional glacial landforms or presently glacierised areas of the Northern Hemisphere. The ecological and geomorphic effects of extreme meteorological and hydrological events, such as episodes of strongly increased precipitation, temperatures and flows, can be exacerbated by altered base conditions. For example, winter temperature variations between frost and thaw will become more frequent at many places because mean temperature during the winter is closer to 0 °C, potentially leading to changes in the production of ice and intensified disturbance of riparian and aquatic habitats during extreme floods. Additionally, thawing of permafrost and glaciers can lead to increased bank erosion because of thaw slump and glacial outburst floods. We discuss the abiotic and biotic effects of these and other extreme events, including heavy precipitation, floods, drought and extreme air or water temperatures, and summarise our findings in a model that aims to stimulate further research in this field.

“…More formal monitoring initiatives require a thoughtful approach to planning how different kinds of knowledge can be involved in different stages of a project, including the data analysis phase. Efforts to identify methods for linking Indigenous and scientific knowledge production approaches should be a priority of future work in this field (Gill et al, 2011;Culp et al, 2012;Russell et al, 2013).…”

ABSTRACT. Community-based monitoring (CBM) in the Arctic is gaining increasing support from a wide range of interested parties, including community members, scientists, government agencies, and funders. Through CBM initiatives, Arctic residents conduct or are involved in ongoing observing and monitoring activities. Arctic Indigenous peoples have been observing the environment for millennia, and CBM often incorporates traditional knowledge, which may be used independently from or in partnership with conventional scientific monitoring methods. Drawing on insights from the first Arctic Observing Summit, we provide an overview of the state of CBM in the Arctic. The CBM approach to monitoring is centered on community needs and interests. It offers fine-grained, local-scale data that are readily accessible to community and municipal decision makers. In spite of these advantages, CBM initiatives remain little documented and are often unconnected to wider networks, with the result that many practitioners lack a clear sense of the field and how best to support its growth and development. CBM initiatives are implemented within legal and governance frameworks that vary significantly both within and among different national contexts. Further documentation of differences and similarities among Arctic communities in relation to observing needs, interests, and legal and institutional capacities will help assess how CBM can contribute to Arctic observing networks. While CBM holds significant potential to meet observing needs of communities, more investment and experimentation are needed to determine how observations and data generated through CBM approaches might effectively inform decision making beyond the community level.Key words: community-based monitoring; traditional knowledge; observing networks; environmental change; sustainability; knowledge management; natural resource management RÉSUMÉ. Dans l'Arctique, la surveillance communautaire (SC) reçoit un appui de plus en plus grand de la part de nombreuses parties intéressées, dont les membres de la communauté, les scientifiques, les organismes gouvernementaux et les bailleurs de fonds. Dans le cadre des initiatives de SC, des habitants de l'Arctique effectuent des tâches permanentes d'observation et de surveillance ou participent à de telles tâches. Les peuples indigènes de l'Arctique observent l'environnement depuis des millénaires. Souvent, la SC fait appel aux connaissances traditionnelles, connaissances qui peuvent être employées seules ou conjointement avec les méthodes classiques de surveillance scientifique. Nous nous sommes appuyés sur les connaissances dérivées du premier sommet d'observation de l'Arctique pour donner un aperçu de l'état de la SC dans l'Arctique. La méthode de SC est centrée sur les besoins et les intérêts de la communauté. Elle permet d'obtenir des données à grain fin à l'échelle locale, données qui sont facilement accessibles par la communauté et les preneurs de décisions municipaux. Malgré ces avantages, il existe peu de documentation au sujet...
