In this article, we share findings from a community-based Participatory Action Research project, titled Sanala, which means to be whole in Kwak’wala—the language of the Kwakwaka’wakw (Kwak̓wala-speaking people; a First Nation from what is now called Canada). In response to community priorities, the Sanala team initiated regalia as a weekly programme where people from the ‘Namgis tribe and other surrounding Kwakwaka’wakw Nations on the northwest coast of British Columbia, Canada, come together to create regalia. Participants learn about family crests, design and sew button blankets and dance aprons, and learn oral histories belonging to individuals and families, all within the context of Kwak’wala language revitalization and regalia making. We outline the impacts of this programme on identity, belonging, wholistic health and collective wellbeing, as well as implications for Participatory Action Research and community-led research aimed at strengthening individual and collective health and wellness through Indigenous languages and cultural continuity.

The article is devoted to the discussion among Soviet and U.S. scholars about the social organization of the Indians of the Northwest Coast of North America. In the classic textbooks on “primitive history”, the Indians of this region—the Tlingit, Haida, Tsimshian and Kwakwaka’wakw (Kwakiutl)—are mentioned as examples of a high degree of social differentiation based on a (fishing and maritime) foraging economy and even as instances of pre-state structures. The proposed concepts were, to varying degrees, determined by external factors: personal political views, high-profile events, or government pressure. In 1897, Franz Boas recognized the potlatch ceremony—demonstrative exchanges of gifts and destructions of surplus, a practice exotic to Europeans—as an analogue of a credit operation. This interpretation, not empirically substantiated, originated from a public campaign to legalize potlatch. In the 1930s, Julia Averkieva, a Soviet intern of Boas, interpreted some fragments of her mentor’s teaching through the Marxist class theory framework, shifting the emphasis from potlatch to slavery: the Northwest Indians allegedly began the transition to slavery from a classless system in which the potlatch was an instrument for preserving property equality. Averkieva’s interpretation became canonical in the USSR, whilst also finding some reception outside the socialist camp. In the United States, relativistic cultural interpretations dominated; domestic evolutionary Marxist models were marginal and were not rooted in the Soviet tradition. However, after the collapse of the USSR, they also became part of the research mainstream, being criticized not only from the right, but also from the left—from anarchist viewpoints.

Abstract Coral bleaching has recently occurred extensively over the world’s oceans, primarily due to high water temperatures. Mesophotic corals that inhabit at depths of approximately 30–150 m are expected to survive during bleaching events and to reseed shallow water corals afterward. In particular, in Okinawa, Japan, mesophotic coral ecosystems (MCEs) have been reported to serve as a refuge to preserve genotypic diversities of bleaching-sensitive corals. Connectivity of larval populations between different habitats is a key element that determines the area to be conserved for desirable coral ecosystems. Coral larvae generally behave passively to the surrounding currents and are transported by the advective and dispersive effects of ambient ocean currents. Thus, numerical ocean circulation models enable us to quantify connectivity with detailed spatiotemporal network structures. Our aim in this study is to quantify the short-distance and vertical connectivity of coral larvae in reef areas on the northwest coast of Okinawa Main Island. For the reason that both short-distance and vertical larval transport are influenced by complex nearshore topography, a very high-resolution 3-D circulation model is required. Therefore, we developed a quadruple nested high-resolution synoptic ocean model at a lateral spatial resolution of 50 m, coupled with an offline 3-D Lagrangian particle-tracking model. After validation of the developed model, short-distance horizontal coral connectivity across reef areas on the northwest coast was successfully evaluated. Furthermore, a series of Lagrangian particle release experiments were conducted to identify the vertical coral migration and 3-D connectivity required for the preservation of MCEs. The model revealed that coral larvae released from the semi-enclosed areas tended to remain near the source area, whereas they were diffused and dispersed gradually with time. The mesophotic corals were dispersed vertically to the deeper zone below the mixed layer, while upward transport occurred to induce the mesophotic corals to emerge near the surface, under the influence of the surface mixed layer. The model results solidly indicated significant connectivity between MCEs and shallow coral ecosystems.

This exhibition review essay compares three recent interventions into historic cultural representations at the American Museum of Natural History: the Digital Totem that was placed in the Northwest Coast Hall in 2016 to partially modernize its content, the 2018 reconsideration of the Old New York Diorama, which attempts to correct its stereotypical representations of Native North American peoples, and the 2019 exhibition Addressing the Statue providing context for the Theodore Roosevelt statue. Paying attention to visual and textual strategies, I characterize these three interventions as temporary annotations to what have been remarkably static, long-term cultural representations. I argue that, through these annotations, the museum acknowledges the misrepresentations but does not resolve them. The case studies show varying degrees of critical historical reflection expressing the complexities of negotiating different approaches and agendas to engaging with the museum’s past. I also comment on the pervasiveness of a digital aesthetics in all three projects, even though only the Digital Totem was produced as a digital, interactive intervention into the museum space. The invocation of a digital design vocabulary enhances the impression of annotation.

Fifteen species of insect herbivores were discovered on ferns growing along the Pacific northwest coast of North America. These included insects from the orders: Diptera in the families Anthomyiidae, Cecidiomyiidae and Syrphidae: Lepidoptera in the families Erebidae, Tortricidae and Noctuidae: Hymenoptera in the family Tenthredinidae: Hemiptera in the family Aphididae and Coleoptera in the family Curculionidae.  The present study illustrates these associations that provides new world and North American host records of fern herbivores. The fossil record of these families is used to determine if the most ancient of these insects (dating from the Mesozoic) are now mostly restricted to ferns and the most recent ones (dating from the Cenozoic) are mostly polyphagous, feeding on ferns as well as various angiosperms.  Results indicate that the insect clades belonging to the most ancient families, such as Aneugmenuss and Strongylogaster in the Tenthredinidae and Dasineura and Mycodiplosis in the Cecidiomyiidae, appear to be monophagous on ferns.

AbstractThe historic extirpation and subsequent recovery of sea otters (Enhydra lutris) have profoundly changed coastal social-ecological systems across the northeastern Pacific. Today, the conservation status of sea otters is informed by estimates of population carrying capacity or growth rates independent of human impacts. However, archaeological and ethnographic evidence suggests that for millennia, complex hunting and management protocols by Indigenous communities limited sea otter abundance near human settlements to reduce the negative impacts of this keystone predator on shared shellfish prey. To assess relative sea otter prevalence in the Holocene, we compared the size structure of ancient California mussels (Mytilus californianus) from six archaeological sites in two regions on the Pacific Northwest Coast, to modern California mussels at locations with and without sea otters. We also quantified modern mussel size distributions from eight locations on the Central Coast of British Columbia, Canada, varying in sea otter occupation time. Comparisons of mussel size spectra revealed that ancient mussel size distributions are consistently more similar to modern size distributions at locations with a prolonged absence of sea otters. This indicates that late Holocene sea otters were maintained well below carrying capacity near human settlements as a result of human intervention. These findings illuminate the conditions under which sea otters and humans persisted over millennia prior to the Pacific maritime fur trade and raise important questions about contemporary conservation objectives for an iconic marine mammal and the social-ecological system in which it is embedded.

Abstract Arctic landfast sea ice (LFSI) represents an important quasi-stationary coastal zone. Its evolution is determined by the regional climate and bathymetry. This study investigated the seasonal cycle and interannual variations of LFSI along the northwest coast of Kotelny Island. Initial freezing, rapid ice formation, stable and decay stages were identified in the seasonal cycle based on application of the visual inspection approach (VIA) to MODIS/Envisat imagery and results from a thermodynamic snow/ice model. The modeled annual maximum ice thickness in 1995–2014 was 2.02 ± 0.12 m showing a trend of −0.13 m decade−1. Shortened ice season length (−22 d decade−1) from model results associated with substantial spring (2.3°C decade−1) and fall (1.9°C decade−1) warming. LFSI break-up resulted from combined fracturing and melting, and the local spatiotemporal patterns of break-up were associated with the irregular bathymetry. Melting dominated the LFSI break-up in the nearshore sheltered area, and the ice thickness decreased to an average of 0.50 m before the LFSI disappeared. For the LFSI adjacent to drift ice, fracturing was the dominant process and the average ice thickness was 1.56 m at the occurrence of the fracturing. The LFSI stages detected by VIA were supported by the model results.
