The need for transformative changes in the use of Indigenous knowledge along with science for environmental decision‐making in the Arctic

© 2020 The Authors. 1. Recent attention to the role of Indigenous knowledge (IK) in environmental monitoring, research and decision-making is likely to attract new people to this field of work. 2. Advancing the bringing together of IK and science in a way that is desirable to IK holders can lead to successful and inclusive research and decision-making. 3. We used the Delphi technique with 18 expert participants who were IK holders or working closely with IK from across the Arctic to examine the drivers of progress and limitations to the use of IK along with science to inform decision-making related to wildlife, reindeer herding and the environment. We also used this technique to identify participants' experiences of scientists' misconceptions concerning IK. 4. Participants had a strong focus on transformative change relating to the structure of institutions, politics, rights, involvement, power and agency over technical issues advancing or limiting progress (e.g. new technologies and language barriers). 5. Participants identified two modes of desirable research: coproducing knowledge with scientists and autonomous Indigenous-led research. They highlighted the need for more collaborative and coproduction projects to allow further refinement of approaches and more funding to support autonomous, Indigenous-led research. 6. Most misconceptions held by scientists concerning IK that were identified by participants related to the spatial, temporal and conceptual scope of IK, and the perceived need to validate IK using Western science. 7. Our research highlights some of the issues that need to be addressed by all participants in research and decision-making involving IK and science. While exact approaches will need to be tailored to specific social-ecological contexts, consideration of these broader concerns revealed by our analysis are likely to be central to effective partnerships.Anglia Ruskin University; EC H2020 Projects INTAROS and CAPARDUS.

A Functional Genomics Approach to Establish the Complement of Carbohydrate Transporters in Streptococcus pneumoniae

The aerotolerant anaerobe Streptococcus pneumoniae is part of the normal nasopharyngeal microbiota of humans and one of the most important invasive pathogens. A genomic survey allowed establishing the occurrence of twenty-one phosphotransferase systems, seven carbohydrate uptake ABC transporters, one sodium∶solute symporter and a permease, underlining an exceptionally high capacity for uptake of carbohydrate substrates. Despite high genomic variability, combined phenotypic and genomic analysis of twenty sequenced strains did assign the substrate specificity only to two uptake systems. Systematic analysis of mutants for most carbohydrate transporters enabled us to assign a phenotype and substrate specificity to twenty-three transport systems. For five putative transporters for galactose, pentoses, ribonucleosides and sulphated glycans activity was inferred, but not experimentally confirmed and only one transport system remains with an unknown substrate and lack of any functional annotation. Using a metabolic approach, 80% of the thirty-two fermentable carbon substrates were assigned to the corresponding transporter. The complexity and robustness of sugar uptake is underlined by the finding that many transporters have multiple substrates, and many sugars are transported by more than one system. The present work permits to draw a functional map of the complete arsenal of carbohydrate utilisation proteins of pneumococci, allows re-annotation of genomic data and might serve as a reference for related species. These data provide tools for specific investigation of the roles of the different carbon substrates on pneumococcal physiology in the host during carriage and invasive infection

Systematic Review and Critique of the Contributions of Traditional Ecological Knowledge of Beluga Whales in the Marine Mammal Literature + Supplementary Appendix Table (See Article Tools)

In this study we systematically review and critique literature containing Traditional Ecological Knowledge (TEK) of the beluga (Delphinapterus leucas) as a case study to gain insights into TEK’s contributions to the marine mammal literature over the past four decades. We reviewed multiple searchable online databases, collected both academic and grey literature, and categorized it by geographic and disciplinary focus, as well as by the contribution of TEK to the source. Of the total 137 papers retained in the final analysis, 67% referred to the Canadian North, particularly the Hudson Bay subregion. Articles that included informal or anecdotal representations of TEK of belugas were the most prevalent. The number of papers containing TEK of belugas increased rapidly between 1975 and 2004 but appears to have leveled off since then. Biological papers represented the largest disciplinary focus (72%), followed by papers on management or co-management. This review showed that although knowledge of Indigenous peoples has made substantial contributions to the understanding of beluga, there is a lack of explicit collection, documentation, and use of TEK in the literature on belugas and particularly in the literature on beluga management. Dans cette étude, nous avons passé en revue de manière systématique la littérature existante sur les connaissances écologiques traditionnelles (CÉT) des bélugas (Delphinapterus leucas) et nous l’avons critiquée en tant qu’étude de cas dans le but de mieux comprendre la contribution des CÉT aux connaissances existantes sur les mammifères marins au cours des quatre dernières décennies. Différentes bases de données consultables en ligne ont été examinées, puis des articles publiés dans des revues scientifiques et des écrits provenant de la littérature grise ont été recueillis, après quoi ceux-ci ont été classés par emplacement géographique, discipline, ainsi que par leur utilisation des CÉT. Au total, 137 documents ont été retenus pour les analyses finales, dont 67 % faisaient référence au nord du Canada, en particulier la sous-région de la baie d’Hudson. Les articles contenant des informations non publiées ou des anecdotes sur la représentation des CÉT sur les bélugas ont figuré parmi les articles les plus abondants. Les documents contenant des CÉT sur les bélugas ont augmenté rapidement entre 1975 et 2004, mais leur nombre semble s’être maintenu depuis. Les articles de biologie ont représenté la majorité des documents (72%), suivis de ceux axés sur la gestion ou la cogestion. Cette revue de la littérature montre que bien que les connaissances des peuples autochtones aient contribué à une compréhension nettement meilleure des bélugas, il y a un manque de rigueur dans la manière de recueillir, de documenter et d’utiliser les CÉT dans la littérature sur le béluga, particulièrement la littérature celle axée sur la gestion. 

Inuit Knowledge of Beluga Whale (Delphinapterus leucas) Foraging Ecology in Nunavik (Arctic Quebec), Canada

The beluga whale (Delphinapterus leucas (Pallas, 1776)) is expected to be influenced by changes in the environment. In Nunavik, the Arctic region of Quebec, Nunavimmiut (Inuit of Nunavik) have depended on beluga for centuries developing an extensive understanding of the species and its ecology. Forty semi-directive interviews were conducted with Inuit hunters and Elders from four Nunavik communities, who had a range of 28 to 47 years of beluga hunting experience. Interviews followed an ethnocartographic format and were analyzed using a mixed methods approach. Hunters most commonly reported prey species from the sculpin, cod, salmon, and crustacean families; regional variations in prey as well as foraging habitat were found. Hunters identified significant changes in body condition (i.e. blubber thickness), which were associated with observations about the seasonality of feeding. The timing of fat accumulation in the late fall and winter coupled with the understanding that Hudson Bay is not known as a productive area suggest alternate hypotheses to feeding for the seasonal movements exhibited by these whales. Inuit Knowledge of beluga foraging ecology presented here provides information on diet composition and seasonality of energy intake of the beluga and can be an important component of monitoring diet composition for this species into the future.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Beluga whale stewardship and collaborative research practices among Indigenous peoples in the Arctic

Beluga whales (Delphinapterus leucas) are an integral part of many Arctic Indigenous cultures and contribute to food security for communities from Greenland, across northern Canada and Alaska to Chukotka, Russia. Although the harvesting and stewardship practices of Indigenous peoples vary among regions and have shifted and adapted over time, central principles of respect for beluga and sharing of the harvest have remained steadfast. In addition to intra-community cooperation to harvest, process and use beluga whales, rapid environmental change in the Arctic has underscored the need for inter-regional communication as well as collaboration with scientists and managers to sustain beluga populations and their cultural and nutritional roles in Arctic communities. Our paper, written by the overlapping categories of researchers, hunters, and managers, first provides an overview of beluga hunting and collaborative research in seven regions of the Arctic (Greenland; Nunatsiavut, Nunavik, Nunavut, and the Inuvialuit Settlement Region, Canada; Alaska; and Chukotka). Then we present a more detailed case study of collaboration, examining a recent research and management project that utilizes co-production of knowledge to address the conservation of a depleted population of beluga in Nunavik, Canada. We conclude that sustaining traditional values, establishing collaborative management efforts, the equitable inclusion of Indigenous Knowledge, and respectful and meaningful collaborations among hunters, researchers and managers are essential to sustaining healthy beluga populations and the peoples who live with and depend upon them in a time of rapid social and environmental change
