Wetlands of the Laurentian Great Lakes of North America (i.e. lakes Superior, Michigan, Huron, Erie, and Ontario) provide critical habitat for marsh birds. We used 11 years (2011–2021) of data collected by the Great Lakes Coastal Wetland Monitoring Program at 1,962 point-count locations in 792 wetlands to quantify the first-ever annual abundance indices and trends of 18 marsh-breeding bird species in coastal wetlands throughout the entire Great Lakes. Nine species (50%) increased by 8–37% per year across all of the Great Lakes combined, whereas none decreased. Twelve species (67%) increased by 5–50% per year in at least 1 of the 5 Great Lakes, whereas only 3 species (17%) decreased by 2–10% per year in at least 1 of the lakes. There were more positive trends among lakes and species (n  = 34, 48%) than negative trends (n  = 5, 7%). These large increases are welcomed because most of the species are of conservation concern in the Great Lakes. Trends were likely caused by long-term, cyclical fluctuations in Great Lakes water levels. Lake levels increased over most of the study, which inundated vegetation and increased open water-vegetation interspersion and open water extent, all of which are known to positively influence abundance of most of the increasing species and negatively influence abundance of all of the decreasing species. Coastal wetlands may be more important for marsh birds than once thought if they provide high-lake-level-induced population pulses for species of conservation concern. Coastal wetland protection and restoration are of utmost importance to safeguard this process. Future climate projections show increases in lake levels over the coming decades, which will cause "coastal squeeze" of many wetlands if they are unable to migrate landward fast enough to keep pace. If this happens, less habitat will be available to support periodic pulses in marsh bird abundance, which appear to be important for regional population dynamics. Actions that allow landward migration of coastal wetlands during increasing lake levels by removing or preventing barriers to movement, such as shoreline hardening, will be useful for maintaining marsh bird breeding habitat in the Great Lakes.

In the context of sustainable management of the Mulet River watershed, a set of conservation and restoration measures were identified through a participatory approach supported by scientific literature. The system of local actors involved in this process was defined with the help of local partner organizations working in the territory. In order to evaluate the measures according to their overall performance and to group them into robust baskets of measures, the multi-criteria decision-making support approach in a multi-actor context was used. This allows the identified measures to be compared and ranked by taking into account various criteria and indicators, and the values and preferences of the different actors involved, in order to facilitate negotiation with a view to building a consensual and shared solution, consisting of baskets of measures. By applying this approach, resulting in a good level of agreement between the stakeholders of the watershed, several measures belonging to the agronomic, plant, mechanical, socio-cultural and socio-political categories were retained, and structured into intervention baskets according to the levels of degradation of the watershed. The implementation of these measures aims to make the watershed better adapted to the impacts of climate change and variability, while improving the living conditions of local communities.

The 28th conference of the parties COP-28 of the United Nations Framework Convention on Climate Change (UNFCCC) sparked strong and divided reactions. On one hand, the influence exerted by the fossil fuel industry, through the choice of the host country and the conference president, was sharply criticized. On the other hand, the progress made on losses and damages, and most of all the final declaration calling for a transition away from fossil fuels were favorably received, despite some drawbacks. We will examine the conference through the eyes of four influent media from four different countries (Canada, France, Germany, United Kingdom), bringing to the fore the opinions voiced by these media and the actors expressing themselves in them, regarding the process and results of COP-28.

Les changements climatiques et les ressources en eau entretiennent des liens essentiellement négatifs qui se manifestent notamment par l'indisponibilité de l’eau, la sècheresse, la désertification et bien d’autres crises hydroclimatiques. Ces interactions factuelles devraient favoriser des interférences entre le droit du climat et le droit de l’eau dont les modèles actuellement en vigueur doivent être revus et améliorer.

Worldwide, migratory phenology and movement of many bird species is shifting in response to anthropogenic climate and habitat changes. However, due to variation among species and a shortage of analyses, changes in waterfowl migration, particularly in the fall, are not well understood. Fall migration phenology and movement patterns dictate waterfowl hunting success and satisfaction, with cascading implications on economies and support for habitat management and securement. Using 60 years of band recovery data for waterfowl banded in the Canadian Prairie Pothole Region (PPR), we evaluated whether fall migration timing and/or distribution changed in Mallard (Anas platyrhynchos), Northern Pintail (A. acuta), and Blue-winged Teal (Spatula discors) between 1960 and 2019. We found that in the Midcontinent Flyways, Mallards and Bluewinged Teal migrated faster in more recent time periods, whereas Northern Pintail began fall migration earlier. In the Pacific Flyway, Mallards began fall migration earlier. Both Mallards and Northern Pintails showed evidence of short-stopping in the Midcontinent Flyways. Indeed, the Mallard and Northern Pintail distribution of band recovery data shifted 180 and 226 km north, respectively, from 1960 to 2019. Conversely, Bluewinged Teal recovery distributions were consistent across years. Mallards and Northern Pintails also exhibited an increased proportion of band recoveries in the Pacific Flyway in recent decades. We provide clear evidence that the timing and routes of fall migration have shifted over the past 6 decades, but these phenological and spatial shifts differ among species. We suggest that using community-science data collected by hunters themselves to explain one of the group's major concerns (changes in duck abundance at traditional hunting grounds), within the environmental lens of climate change, may help lead to further engagement and two-way dialogue to support effective waterfowl management for these culturally and ecologically important species.

Climate change risks to coastal communities may overwhelm current management strategies. The emergence of nature‐based solutions could provide alternative approaches for climate adaptation; however, studies on their public acceptability are limited. This research focuses on the human dimensions of nature‐based coastal adaptation solutions. The research sought to understand the kind of environmental changes participants were experiencing in their coastal communities of Nova Scotia and what management responses they observed being taken, if any. Online focus groups were held with coastal property owners in Nova Scotia to understand how they assess coastal risks and four approaches to nature‐based coastal adaptation: living shorelines, accommodation, retreat, and dyke realignment to make space for wetland restoration. Results revealed ongoing trust in traditional hard‐line approaches, but also interest in knowing more about nature‐based options. There was general support for living shorelines, albeit with scepticism; a concern that accommodation is just a "band‐aid" approach; resistance to retreat, despite general recognition of its future utility; and a lack of understanding of dyke realignment. The successful implementation of nature‐based coastal adaptation approaches will require more evidence of their viability, better options for financing them, and engagement with communities around the best‐fit alternatives for them. Key messages: In focus groups, coastal residents expressed needs for proof of viability and financing to enhance buy‐in to nature‐based solutions.Living shorelines were supported, but with scepticism about their effectiveness, although dyke realignment was often misunderstood.Accommodation was seen as a "band‐aid" and almost as unpopular as coastal retreat.

Le présent article trouve sa source dans le documentaire militant Inuk en colère (Angry Inuk , 2016), de la cinéaste inuite Alethea Arnaquq-Baril. Enchâssé dans l'argumentation d' Inuk en colère pour le droit de faire le commerce des produits du phoque afin que sa consommation ne se limite pas à la subsistance locale repose l'impératif écologique capital de réévaluer sérieusement les modes de savoir eurocentriques inappropriés et leur exclusion des traditions scientifiques complémentaires tirées de points de vue non européens. Par conséquent, la présente étude analyse le dévoilement que fait Inuk en colère de la dépendance de la durabilité écologique et économique à un cadre épistémologique plus profond, non dominé par des points de vue occidentaux, et qui, en toute logique, appuie des objectifs à long terme de vitalité plutôt que d'accumulation. L'article s'appuie sur les principes exposés dans le documentaire d'Alethea Arnaquq-Baril pour analyser des œuvres populaires d'écocinéma de tous genres. Il propose des analyses comparatives des textes de film dans leur contexte socioculturel et esthétique, de manière à mettre en relief les recherches scientifiques et philosophiques autochtones. L'article tente donc de débusquer les lacunes engendrées par les traditions eurocentriques dominantes qui continuent de régir les sciences de l'environnement occidentales et d'en influencer l'expression dans le cinéma populaire, ce qui renforce et perpétue des hypothèses scientifiques hégémoniques boiteuses. À ce titre, le présent article vise à jeter la lumière sur les failles épistémologiques sous-jacentes qui inhibent la création d'œuvres écocinématographiques paradigmatiques percutantes et à vaste portée en mesure de définir le genre. This article takes as its starting point Inuk filmmaker Alethea Arnaquq-Baril's activist documentary Angry Inuk (2016). Embedded within Angry Inuk 's argument for the right to trade seal products for consumption beyond local subsistence lies the crucial ecological imperative to profoundly reconsider inadequate Eurocentric ways of knowing and their exclusion of complementary scientific traditions based in non-European world-views. The current study therefore considers Angry Inuk 's unveiling of the dependence of ecological and economic sustainability on a deeper epistemological framework not dominated by Western worldviews that coherently supports long-term objectives privileging vitality rather than accumulation. Using the principles exhibited in Arnaquq-Baril's documentary as a springboard, the article goes on to place these into conversation with key mainstream works of ecocinema across genres. It thus proposes comparative analyses of film texts alongside their sociocultural and aesthetic contexts within a framework that foregrounds Indigenous scientific and philosophical scholarship. The article thereby seeks to uncover the lacunae engendered by dominant Eurocentric traditions that continue to govern Western environmental science and influence its expressions in mainstream cinema, which in turn reinforce and perpetuate flawed hegemonic scientific assumptions. As such, the current investigation aims to shed light on underlying epistemological shortcomings that inhibit the creation of wide-reaching, paradigmatic, impactful, and genre-defining works of ecocinema.

Résumé: Les changements climatiques occupent une place centrale en gouvernance mondiale de l'environnement. Vu l'envergure des défis à résoudre, la plus récente Conférence des Parties (CdP) de la Convention-cadre des Nations Unies sur les changements climatiques (CCNUCC), la CdP-27, faisait face à de grandes attentes. Ce court article offre un bilan critique de la CdP-27. L'article présente une synthèse des résultats de cette CdP en étudiant quatre volets principaux, soit l'atténuation des émissions de gaz à effet de serre (GES), l'augmentation du financement climatique, l'adaptation aux changements climatiques et les pertes et préjudices. Il dresse ainsi un portait des résultats de la CdP-27 au regard des attentes qui avaient été établies au préalable par les parties prenantes. L'article se conclut par une analyse prospective des principaux enjeux à suivre d'ici la CdP-28 et au-delà. Il permet ainsi de faire le point sur les plus récents développements, d'éclairer les avancées à venir et de contribuer aux discussions sur la gouvernance mondiale du climat. Climate change is a central issue in global environmental governance. Given the scale of the challenges, the most recent Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC), COP 27, was faced with high expectations. This short article provides a critical assessment of COP 27. It offers an overview of the results of this COP by examining four main components–namely, mitigation of greenhouse gas (GHG) emissions, increased climate finance, adaptation to climate change, and loss and damage. It provides a snapshot of the outcomes of COP-27 in relation to the expectations that were previously set by stakeholders. The article concludes with a prospective analysis of the main issues to be followed up by COP 28 and beyond. It thus provides an update on the most recent developments, sheds light on future progress, and contributes to discussions on global climate governance. [ABSTRACT FROM AUTHOR]

Les villes haïtiennes s'accroissent dans l'irrespect des normes urbanistiques globalement depuis les années 1980 et, parallèlement, le climat d'Haïti se réchauffe progressivement et de façon non négligeable en perturbant la régularité de la température, des saisons et du niveau de la mer. Dans le but de mettre en rapport les changements climatiques et la croissance urbaine de Port-au-Prince, tout en mettant l'accent sur leurs impacts sur les ressources en eau, nous avons réalisé des observations de terrain, des entretiens avec des chercheurs (hydrologues), des analyses des documents écrits et iconographiques (cartes, images satellites). En effet, les résultats montrent que l'eau fait face à des problèmes à différents niveaux tant sur le plan quantitatif que sur le plan qualitatif. Le débit de nombreuses sources diminue considérablement et l'eau est contaminée tant au niveau du système d'adduction d'eau potable, des nappes phréatiques, des cours d'eau qu'au niveau de la mer. Outre la pollution des eaux souterraines, marines et de surface qui compromet la santé et la biodiversité marine, la population fait face aussi au risque d'inondation et de houle causant des dégâts de plus en plus importants et inquiétants. Dans cette situation de crise notamment urbaine et climatique qui menace les ressources hydriques sans lesquelles aucune société humaine ne peut exister, les acteurs concernés doivent envisager des stratégies efficacement adaptées à ces problèmes afin d'envisager la croissance de la ville de Port-au-Prince et celles d'Haïti en général face aux changements climatiques, sur une base de développement durable et à travers une approche holistique. Haitian cities have been growing without regard for global urban planning standards since the 1980s. Simultaneously, Haiti's climate is gradually and significantly warming, as measured through disruptions of long-observed patterns of temperature, seasons, and sea levels. Recognizing that climate change and urban growth in Port-au-Prince [End Page 42] both impact water resources as separate but interlinked forces, we carried out field observations, interviews with researchers (specifically hydrologists), and analyses of written documents as well as maps, satellite images, etc. to understand how these phenomena are linked and mutually exacerbating. Effectively, study results indicate a range of problems with water quantity and quality: the flow of numerous crucial water sources has considerably diminished, and water is widely contaminated, from drinking water to groundwater to rivers, watersheds, and the ocean. Besides the pollution of marine, ground, and surface water, which impacts biodiversity, human health, and marine health, the Haitian population also faces increasingly high risks of flooding and the stresses of related damage. This situation of urban and climate crisis threatens the water resources necessary for human existence. In order to find strategies that are effectively adapted to these problems, we propose a holistic approach that considers the growth of the Port-au-Prince and other Haitian cities in connection with climate change, on a basis of sustainable development.

Dans la Région Grand Est, un des moyens pour expérimenter des méthodes d’adaptation des forêts au changement climatique est la mise en place d’îlots d’avenir permettant de tester dix espèces allochtones sur des placettes comprises entre 1 et 2 ha. Ce projet, appelé FutorforEst, comprend un réseau d’environ 70 placettes aussi bien en forêt publique qu’en forêt privée. L’objectif est d’étudier le comportement de ces espèces en condition de peuplement et de d’évaluer leur résistance aux sécheresses répétées, à la canicule et aux ravageurs. À terme, parmi les espèces prometteuses, un itinéraire technique sylvicole sera développé. Messages clés Le projet FuturForEst met en place des îlots d’avenir. Dix espèces allochtones sont testées. Des suivis permettront d’évaluer leur potentialité pour constituer les forêts du futur.

Les changements climatiques constituent une menace sérieuse pour les ressources pastorales, dégradant les parcours et impactant les populations qui en dépendent. Cette étude vise à identifier les stratégies d’adaptation des éleveurs face aux changements climatiques et à analyser leurs impacts sur la composante pastorale dans les systèmes d’élevage étudiés. Des entretiens semi-directifs et des ateliers participatifs ont été menés auprès de 28 éleveurs, permettant de recueillir des informations sur leurs pratiques et stratégies d’adaptation. Une analyse de l’occupation des sols de 1985 à 2020 a été réalisée pour comprendre les dynamiques de changement des pâturages, accompagnée d’une modélisation de l’évolution des ressources naturelles de 2020 à 2030, offrant une démarche prospective sur l’avenir des ressources pastorales à l’échelle communale. Les résultats ont révélé que les éleveurs tendent vers la sédentarisation en réponse aux sécheresses récurrentes, conduisant à la divergence du système d’élevage pastoral traditionnel en trois systèmes distincts : sédentaire, transhumant occasionnel et transhumant permanent. L’analyse de l’occupation des sols a montré que ces changements ont modifié l’occupation des pâturages. Le développement des infrastructures et des transports a facilité l’accès des transhumants à des parcours éloignés, couvrant ainsi jusqu’à 75 % des besoins alimentaires des ovins avec la végétation pastorale. Les éleveurs sédentarisés pratiquent une supplémentation alimentaire toute l’année, composée principalement de maïs, d’orge, de son de blé et de pulpe de betterave, avec une contribution significative des fourrages à la satisfaction des besoins des ovins (50 à 90 % des besoins). La sédentarisation et la diminution des points d’eau dans les parcours d’altitude contribuent à une surexploitation croissante des parcours de proximité. L’analyse prévisionnelle de l’évolution des ressources naturelles de 2020 à 2030 montre un endommagement irréversible de ces parcours sous les conditions et les pratiques actuelles, appelant à une réflexion approfondie sur des solutions durables pour préserver ces ressources.

À l’heure où le système québécois de santé publique est confronté à différents enjeux en contexte postpandémique, l’heure est aux solutions dans le but d’alléger la charge sur ce dernier et sur les personnes y travaillant. Dans le but de pousser la réflexion et d’identifier des solutions pour favoriser la santé durable, le premier Sommet de la santé durable a été organisé par l’Association de la santé publique du Québec (ASPQ). Il s’est déroulé du 25 au 27 janvier 2023, au Musée de la civilisation de Québec. Ce texte consiste en un compte rendu de l’évènement, suivi d’une analyse éthique afin de souligner les forces du Sommet et les points d’amélioration possibles dans l’optique d’une deuxième édition.

La commune de Djilor est marquée par une tendance à la dégradation des ressources. Elles sont soumises aux effets des changements climatiques. Ainsi, l’étude de la vulnérabilité de la commune de Djilor aux changements climatiques et stratégies d’adaptation des communautés fait l’objet de cette contribution. La démarche intègre les outils d’analyse de la vulnérabilité et de la capacité d’adaptation aux changement climatique (AVCA) et d’identification des risques au niveau communautaire - adaptation et moyens d’existence (CRiSTAL). Cela a permis de faire un diagnostic participatif des menaces, contraintes et opportunités liées aux changements climatiques et aux savoirs endogènes en matière de mesure d’adaptation. Les résultats montrent l’existence de 05 catégories de ressources : les ressources naturelles, les ressources physiques, les ressources humaines, les ressources financières et les ressources sociales. L’analyse de la vulnérabilité révèle que des aléas liés directement ou indirectement à ces changements climatiques sont présents et se manifestent plus par la salinisation, la variabilité pluviométrique, la sécheresse et les inondations. Ces aléas influencent négativement ces ressources et entrainent des conséquences sur l’agriculture, l’élevage, la pêche, l’exploitation forestière, le commerce. Face à cette situation, les populations adoptent des stratégies d’adaptation. Néanmoins, la situation persiste et ses effets sont encore remarquables.

During migration, birds must stopover at refueling sites to replenish energy stores, with the rate of refueling linked to stopover length, migration speed, and the timing of critical life stages, such as breeding. Under optimal migration theory, birds are expected to maximize fuel intake and minimize stopover length (the time minimization hypothesis). Within a multi-species framework, we demonstrate that time minimization behavior is context-dependent, as refueling rate, stopover length, and departure decisions vary between seasons, among species with different ecological traits (e.g., diet and migration distance), and in response to density-dependent factors and prevailing environmental conditions. Using long-term banding data (10 years) from southwestern British Columbia, Canada, we investigated the ecological processes shaping stopover dynamics among 5 warbler (Parulidae) and 5 sparrow species (Passerellidae). Specifically, we assessed variation in fuel deposition rates (FDRs) as well as the associations between mass gain, stopover length, and departure probability. FDR was greater in insectivorous warblers during spring migration and in species migrating long distances. FDR responded positively to temperature and habitat productivity, but negatively to precipitation events, particularly for insectivorous, long-distance migrants during spring migration. Similarly, density-dependent refueling rate was only observed in insectivores and long-distance migrants during spring migration, where higher densities of foliage-gleaning insectivores were associated with a lower FDR. Stopover duration was more closely associated with body condition upon arrival and subsequent mass gain than direct environmental effects, especially during northward spring migration, providing support for time minimization and a mass threshold influencing departure decisions. These results highlight that refueling rates and stopover quality vary among species depending on their life-history strategies, with particular implications for long-distance, migratory insectivores, which may be most susceptible to climate shifts.

L'objectif de cet article est d'étudier l'impact de la vulnérabilité au changement climatique sur la croissance économique. Nous répondons à nos préoccupations en utilisant le modèle de variables instrumentales à long terme de Kripfganz et Sarafidis (2021). Nous testons ensuite l'hypothèse de Kuznets (EKC) en utilisant le modèle à seuil de Hansen (1999). Notre étude porte sur 10 pays pour la période 1995-2020. Les estimations de Kripfganz et Sarafidis (2021) utilisant ce modèle montrent que la vulnérabilité au changement climatique augmente considérablement la croissance économique à un seuil de 1 % d'environ 43,84 %. De plus, les résultats non linéaires utilisant le modèle de Hansen (1999) montrent que : (i) dans les régimes inférieurs, une augmentation de 1 % de la vulnérabilité augmente significativement la croissance économique de 5,242 % au seuil de 5 %. (ii) Sous le régime supérieur, une augmentation de 1 % de la vulnérabilité augmente significativement l'augmentation du seuil de 1 % de 5,856 %. Par conséquent, les résultats du modèle de Hansen (1999) sont cohérents avec ceux du modèle de Kripfganz et Sarafidis (2021). Ces résultats sont robustes aux évaluations de sensibilité et aux estimations des effets fixes.

Environmental change associated with warmer temperatures is creating unprecedented conditions in natural regions and ecosystems. In Jasper National Park, Alberta, climate change, historical fire management practices, and the mountain pine beetle infestation are combining to increase the risk of a major wildfire. The intent of this short viewpoint is to provide a primer for decision makers. The application of an adaptation readiness framework highlights areas where the Park's level of preparedness for wildfire adaptation is well developed and areas in need of further attention. Areas where adaptation is well developed include political leadership, decision making, and stakeholder engagement. Further attention is necessary around institutional organizations, funding, and public support. Key Messages: Risk of wildfire in Jasper National Park is increasing due to combined impacts of climate change, historical fire management practices, and mountain pine beetle infestation.There is need for a long‐term adaptation strategy, including engagement and collaboration between planners, industry professionals, and the community to reduce the risk of wildfire.Areas where adaptation is well developed include political leadership, decision making, and stakeholder engagement, while further attention is necessary around institutional organizations, funding, and public support.

Cet article questionne la pertinence de soutenir la valeur qu’est l’écoresponsabilité et, plus largement, la justice intergénérationnelle dans le contexte de la pratique clinique de l’ergothérapeute. Au moment d’adopter des pratiques professionnelles respectueuses de ces valeurs, l’ergothérapeute peut être amené à vivre un dilemme éthique opposant celles-ci à l’approche centrée sur le client qui est grandement valorisée au sein de la profession. Cet article développe une réflexion éthique sur un des résultats d’une recherche qui a été menée sur les pratiques durables ou écoresponsables en ergothérapie. Plus précisément, nous développons une réflexion éthique sur la légitimité pour l’ergothérapeute de défendre les valeurs que sont l’écoresponsabilité et la justice intergénérationnelle dans un contexte clinique. Pour ce faire, le Cadre éthique quadripartite (CÉQ) – un cadre d’analyse éthique qui a été développé pour soutenir l’ergothérapeute dans ses réflexions éthiques – est mobilisé. Sans apporter une réponse claire ni définitive quant à la pertinence éthique de défendre ces valeurs en clinique, la réflexion ici développée met en lumière des éléments qui pourraient être considérés par l’ergothérapeute qui vit ce dilemme éthique.

This article questions the relevance of supporting the value of eco-responsibility and, more broadly, intergenerational occupational justice in the context of the clinical practice of the occupational therapy. When adopting professional practices that are respectful of these values, occupational therapists may be faced with an ethical dilemma that opposes these values to the client-centred approach that is highly valued within the profession. This article develops an ethical reflection on one of the results of a research study conducted on sustainable or ecoresponsible practices in occupational therapy. More specifically, we develop an ethical reflection on the legitimacy for occupational therapists to defend the values of ecoresponsibility and intergenerational occupational justice in a clinical context. To do so, we mobilize the Quadripartite Ethical Framework (QEF), an ethical analysis framework that was developed to support occupational therapists in their ethical reflections. Without providing a clear or definitive answer as to the ethical relevance of defending these values in a clinical setting, the reflection developed here highlights elements that could be considered by occupational therapists experiencing such an ethical dilemma.

The Pacific Basin, by virtue of its vastness and its complex aeroscape, provides unique opportunities to address questions about the behavioral and physiological capabilities and mechanisms through which birds can complete spectacular flights. No longer is the Pacific seen just as a formidable barrier between terrestrial habitats in the north and the south, but rather as a gateway for specialized species, such as shorebirds, to make a living on hemispherically distributed seasonal resources. This recent change in perspective is dramatic, and the research that underpins it has presented new opportunities to learn about phenomena that often challenge a sense of normal. Ancient Polynesians were aware of the seasonal passage of shorebirds and other landbirds over the Pacific Ocean, incorporating these observations into their navigational "tool kit" as they explored and colonized the Pacific. Some ten centuries later, systematic visual observations and tracking technology have revealed much about movement of these shorebirds, especially the enormity of their individual nonstop flights. This invites a broad suite of questions, often requiring comparative studies with bird migration across other ocean basins, or across continents. For example, how do birds manage many days of nonstop exercise apparently without sleep? What mechanisms explain birds acting as if they possess a Global Positioning System? How do such extreme migrations evolve? Through advances in both theory and tracking technology, biologists are poised to greatly expand the horizons of movement ecology as we know it. In this integrative review, we present a series of intriguing questions about trans-Pacific migrant shorebirds and summarize recent advances in knowledge about migratory behavior operating at temporal scales ranging from immediate decisions during a single flight, to adaptive learning throughout a lifetime, to evolutionary development of migratory pathways. Recent advances in this realm should stimulate future research across the globe and across a broad array of disciplines. [ABSTRACT FROM AUTHOR]

This article excerpts a discussion about performance and climate action that took place during the annual Canadian Association for Theatre Research (CATR) conference, Partition/Ensemble 2020. Ten artists, activists, and academics share their experiences of using performance as a resource in climate-change action. They explore challenges and tactics, detail examples of theatrical climate action, and urge other artists and activists to use the tools of theatre and performance to tell the stories of climate collapse. This article reflects the groundswell of creative energy being brought to the climate crisis, providing an inspiration for others who want to use their artistic skills to support climate action.

Ce texte discute d’une nouvelle vision de la justice, en l’occurrence de la justice occupationnelle intergénérationnelle. En plus de présenter la genèse de cette vision occupationnelle de la justice climatique, la définition et l’explication de cette valeur sont mises en contraste avec d’autres concepts apparentés en ergothérapie et dans la science de l’occupation.
