Rising levels of ultraviolet radiation (UVR) secondary to ozone depletion are an issue concern for public health. Skin cancers and intraepidermal dysplasia increasingly observed in individuals that undergo chronic or excessive sun exposure. Such alterations skin integrity function well established humans laboratory animals, but remain unexplored mammalian wildlife. However, effects unlikely be negligible, particularly species such as whales, whose anatomical life-history traits force them...
A current threat to the marine ecosystem is high level of solar ultraviolet radiation (UV). Large whales have recently been shown suffer sun-induced skin damage from continuous UV exposure. Genotoxic consequences such exposure remain unknown for these long-lived species, as does their capacity counteract UV-induced insults. We show that induces mitochondrial DNA in seasonally sympatric fin, sperm and blue this accumulates with age. However, counteractive molecular mechanisms are markedly...
Since the 1990s, scientists and Indigenous peoples have worked together across Inuit Nunangat (Inuit homeland in Canada) to conduct research on contaminants ringed seals (Pusa hispida; natsiq, natchiq or ᓇᑦᓯᖅ Inuktut), a species of high cultural, economic nutritional importance among Inuit. Developing innovative ways engaging communities has become essential. Here we examine science outreach knowledge mobilization project that was developed as part long-term contaminant monitoring program...
Traditional and local ecological knowledge (TEK/LEK) are important sources of information for wildlife conservation. However, there often limitations biases in the TEK/LEK methods used. In this study, we examined implemented strategies to address identified while analyzing mapped observations collected from 27 interviews as part a larger project on walruses Nunavik (Canadian Arctic). Our main objectives were to: (1) examine importance recording participants' temporal spatial limits...
The Arctic Tern (Sterna paradisaea; takatakiaq in Inuttitut) breeds the circumpolar and undertakes longest known annual migration. In recent decades, populations have been declining some parts of their range, this has a cause concern for both wildlife managers Indigenous harvesters. However, limited scientific information is available on abundance distribution, especially within its breeding range remote areas Arctic. Knowledge held by Inuit harvesters engaged egg picking can shed light...
Walruses, Odobenus rosmarus, play a key role in the Arctic ecosystem, including northern Indigenous communities, which are reliant upon walruses for aspects of their diet and culture. However, face varied environmental threats rising sea-water temperatures decreasing ice cover. An underappreciated threat may be large amount solar ultraviolet radiation (UV) that continues to reach as result ozone loss. UV has been shown negatively affect whales. Like whales, walrus skin is unprotected by fur,...
The cellular mechanisms used to counteract or limit damage caused by exposure of marine vertebrates solar ultraviolet (UV) radiation are poorly understood. Cetaceans vulnerable because they lack protective skin appendages and obliged surface continuously breathe, thus being exposed repeatedly UV light. Although molecular photoprotection cetaceans have been studied, there is limited knowledge about their epidermal structure photoprotective effectors.To describe compare the epidermis mysticete...
Abstract Background Despite international success in reducing ozone-depleting emissions, ultraviolet radiation (UV) is not expected to decrease for several decades. Thus, it pressing implement tools that allow investigating the capacity of wildlife respond excessive UV, particularly species like cetaceans lack anatomical or physiological protection. One approach examine epidermal expression key genes involved genotoxic stress response pathways. However, quantitation mRNA transcripts requires...
Environmental changes are affecting the Arctic at an unprecedented rate, but limited scientific knowledge exists on their impacts species such as walruses (Odobenus rosmarus). Inuit Traditional and Local Ecological Knowledge (Inuit TEK/LEK) held by walrus harvesters could shed light ecology related environmental changes. Our main objective was to study spatial temporal in Atlantic rosmarus rosmarus) distribution Nunavik (northern Québec, Canada) using TEK/LEK. To do so, we documented...
