Using multiple knowledge sources to interpret patterns of biodiversity can generate the comprehensive species characterizations that are required for effective conservation strategies. Caribou (Rangifer tarandus) display substantial intraspecific variation across their distribution and in the Sahtú Region of the Northwest Territories, Canada, three caribou types, each with a different conservation status, co-occur. Caribou are essential to the economies, culture, and livelihoods of northern indigenous peoples. Indigenous communities across the north are insisting that caribou research be community-driven and collaborative. In response to questions that arose through dialogue with five Sahtú Dene and Métis communities, we jointly developed a research approach to understand caribou differentiation and population structure. Our goal was to examine caribou variation through analysis of population genetics and an exploration of the relationships Dene and Métis people establish with animals within bioculturally diverse systems. To cultivate a research environment that supported łeghaǵots'enetę "learning together" we collaborated with Ɂehdzo Got'ınę (Renewable Resources Councils), elders, and an advisory group. Dene knowledge and categorization systems include a comprehensive understanding of the origin, behaviors, dynamic interactions, and spatial structure of caribou. Dene people classify todzı "boreal woodland caribou" based on unique behaviors, habitat preferences, and morphology that differ from ɂekwę "barren-ground" or shuhta ɂepę "mountain" caribou. Similarly, genetic analysis of material (microsatellites and mitochondrial DNA) from caribou fecal pellets, collected in collaboration with community members during the winter, provided additional evidence for population differentiation that corresponded to the caribou types recognized by Dene people and produced insights into the evolutionary histories that contribute to the various forms. We developed culturally respectful and relevant descriptions of caribou variation through partnerships that respect the lives and experiences of people that depend on the land. By prioritizing mutual learning, researchers can broaden their understanding of biodiversity and establish a common language for collaboration.

Aim Glacial-interglacial cycles influenced the contemporary genetic structure of many North American species. While phylogeographical lineage divergence among Pleistocene refugia has been proposed as a significant driver of subspecific and ecotypic differentiation, emerging evidence highlights the role of diversification within refugia in producing post-glacial variation. Caribou (Rangifer tarandus) exhibit significant morphological, ecological and behavioural phenotypic variation and occurred within Beringian and sub-Laurentide refugia. More specifically, the boreal ecotype of woodland caribou ranges from the southern regions of Canada to the Northwest Territories (NWT). Woodland caribou are generally accepted to have evolved south of the glacial extent, but the boreal ecotype in the northern part of their range co-occurs with caribou that have a Beringian origin. This proximity provides an opportunity to test whether woodland caribou colonized boreal habitats from a single southern refugial source or if independent evolution to a common ecotype resulted from diversification within refugia.Location Northwestern Canada.Methods We used approximate Bayesian computation to discriminate between alternate evolutionary histories of caribou belonging to boreal, northern mountain and barren-ground ecotypes using microsatellite and mtDNA markers.Results Our analysis indicates that unlike the southern-evolved boreal ecotype, the boreal ecotype of central NWT has Beringian origins and arose from a common lineage with barren-ground and mountain caribou. Importantly, the divergence of the lineage resulting in the boreal ecotype of central NWT significantly pre-dates the Last Glacial Maximum.Main conclusions We demonstrate that independent evolutionary trajectories can converge on a similar phenotype and for the first time show that the boreal ecotype of caribou in North America contains two phylogeographical assemblages. The ancient divergence suggests that diversification within Beringia could have resulted in ecological specialization. An eco-evolutionary focus will be essential to designing biodiversity conservation strategies for caribou that maximize genetic diversity and preserve adaptive potential in this intraspecifically diverse species.

In the two decades since Alexander Lockhart's seminal article on the insider–outsider dialectic in native socioeconomic development, a great deal of change has occurred in the Canadian North and new challenges have emerged for community‐based participatory research and development. This is particularly the case in the Northwest Territories, where Aboriginal communities are facing for the first time the triple challenges of Aboriginal land claims implementation, Aboriginal self‐government, and a boom in mining and petroleum development. Increasingly, participatory methods in research and community development are being co‐opted to serve state or corporate interests, far from their radical origins in movements for social change. A historical analysis is called for that accounts for the contradictory and contested social contexts in which participatory activities are imbedded. This article suggests that a return to the roots of the participatory method requires the creation of a new autonomous space of resistance. The academic outsider is uniquely positioned to facilitate critical interventions in both community and university contexts. The resulting convergence of critical outsider and insider has great potential in the forging of new knowledge that can contribute to self‐determination beyond the bounds of the state.

ABSTRACT. Interdisciplinary approaches are necessary for exploring the complex research questions that stem from interdependence in social-ecological systems. For example, the concept of biocultural diversity, which highlights the interactions between human diversity and the diversity of biological systems, bridges multiple knowledge systems and disciplines and can reveal historical, existing, and emergent patterns of variation that are essential to ecosystem dynamics. Identifying biocultural diversity requires a flexible, creative, and collaborative approach to research. We demonstrate how visual art can be used in combination with scientific and social science methods to examine the biocultural landscape of the Sahtú region of the Northwest Territories, Canada. Specifically, we focus on the intersection of Dene cultural diversity and caribou (Rangifer tarandus) intraspecific variation. We developed original illustrations, diagrams, and other visual aids to increase the effectiveness of communication, improve the organization of research results, and promote intellectual creativity. For example, we used scientific visualization and drawings to explain complex genetic data and clarify research priorities. Visual facilitation during meetings helped establish accurate representations of both cultural and biological diversity by externalizing heterogeneity and avoiding standardization. Group mind mapping enhanced collaborators' ability to visualize connections between Dene concepts, like bets'erıhchá "respect" and caribou, and to recognize differences between knowledge systems that challenge translations and reduce the effectiveness of research outcomes. Collaborative visual products, like posters that represented different caribou types, allowed Dene partners to more clearly articulate subtleties within caribou intraspecific variation that are manifest through distinct dialects, place-based relationships, and cultural practices. Our results point to the potential for visual art to be used to improve communication, participation, and knowledge production in interdisciplinary and cross-cultural research collaborations and to enhance the sustainable stewardship and protection of biodiversity.
