The European, Canadian, and Latin American seaweed industries rely on the sustainable harvesting of natural resources. As several countries wish to increase their activity, harvest should be managed according integrated participatory governance regimes ensure production within a long-term perspective. Development regulations directives enabling exploitation resources must therefore brought national international political agenda in order environmental, social, economic values coastal areas...
Anthropogenic climate change profoundly alters the ocean’s environmental conditions, which, in turn, impact marine ecosystems. Some of these changes are happening fast and may be difficult to reverse. The identification monitoring such changes, which also includes tipping points, is an ongoing emerging research effort. Prevention negative impacts requires mitigation efforts based on feasible research-based pathways. Climate-induced points traditionally associated with singular catastrophic...
Investigations of hooded seals Cystophora cristata have revealed high prevalences Brucella-positive in the reduced Northeast Atlantic stock, compared to increasing Northwest stock. This study evaluated relation between Brucella-serostatus stock and age, sex, body condition reproduction. Bacteriology documented which animals organs were B. pinnipedialis positive. No relationship was observed or reproductive traits. Pups (<1 mo old) had a substantially lower probability being seropositive...
The effect of variable autumn temperatures in combination with decreasing irradiance and daylength on photosynthesis, growth cessation freezing tolerance was investigated northern- southern-adapted populations perennial ryegrass (Lolium perenne) timothy (Phleum pratense) intended for use regions at northern high latitudes. Plants were subjected to three different acclimation temperatures; 12, 6 9/3°C (day/night) 4 weeks, followed by 1 week cold 2°C under natural light conditions. This...
It has been suggested that animals may escape attack from mobile parasites by aggregating in selfish herds. A herd disperses the risk of being attacked among its members and per individual parasite infection should therefore decrease with increasing animal density through encounter–dilution effect. Moreover, a herd, dominant agile occupy best positions thereby receive fewer attacks compared to lower ranked at periphery. We tested these predictions on reindeer ( Rangifer tarandus )...
A species-independent indirect enzyme-linked immunosorbent assay (iELISA) based on chimeric protein A/G was established for the detection of anti- Brucella antibodies in Arctic wildlife species and compared to previously brucellosis serological tests hooded seals ( Cystophora cristata), minke whales Balaenoptera acutorostrata), sei borealis), fin physalus), polar bears Ursus maritimus), as well bacteriology results reindeer caribou Rangifer tarandus sp.). The iELISA were consistent with...
The environmental temperature has profound effects on biological systems of marine aquatic organisms and plays a critical role in species distribution abundance. Particularly during the warmer seasons, variations habitat may introduce episodes stressful temperatures which must adapt to compensate for maintain physiological homeostasis. environment is changing predicted raises water will affect numerous species. Translocation pathogens follow migration alternations physical parameters have...
Brucella pinnipedialis was first isolated from true seals in 1994 and eared 2008. Although few pathological findings have been associated with infection seals, reproductive pathology including abortions, the isolation of zoonotic strain type 27 documented seals. In this study, a enzyme-linked immunosorbent assay (ELISA) Rose Bengal test (RBT) were initially compared for 206 serum samples discrepancy between tests found. Following removal lipids samples, ELISA results unaltered while...
Abstract The expected temperature rise in late summer/early autumn can change the conditions for acclimation and affect winter survival of perennial crops. This study examined effect just before onset cold (pre‐acclimation) on freezing tolerance timothy ( Phleum pratense L.), ryegrass Lolium perenne L.) red clover Trifolium populations (both cultivars breeding populations) adapted to either northern or southern parts Norway. Using phytotron experiments, we studied whether increasing...
1. In reindeer, the variation in fur coloration is higher semi-domesticated than wild populations. This difference might result from impacts of natural enemies acting on conspicuously coloured individuals with intensity 2. While predator pressure rather similar for and populations, reindeer are less impacted by parasitism due to endectocidic treatment. this study, we estimated warble flies different colour morphs a large sample untreated calves multiple herds northern Norway. 3.

Abstract Background Reindeer herding in Norway is based on traditional Sámi pastoralism with the animals free ranging throughout year. The move over large areas varying terrain and often challenging weather conditions. Winter crises, such as difficult grazing conditions caused by icing or amounts of snow, are survival bottlenecks for reindeer. Calves especially vulnerable, many may die from starvation during winter crises. Predation predominant narratives to explain losses, however,...
Tipping points in the Earth system could be passed within Paris Agreement's global temperature goal range (1.5°C – 2°C). tipping processes have received limited attention from environmental governance community. Existing institutions do not directly address these challenges. The common toolkit of decision making, is a poor match for processes, especially implications non-linear change, reversibility, and radical intertemporality. For makers to respond effectively rapid state changes system,...
Assessing dental wear is a useful tool for monitoring the interaction between ungulates and their food resources. However, using univariate measurement wear, like instance height of first molar may not capture variation in important functional morphology. We here demonstrate method assessing by geometric morphometrical methods on 11 mandibles from nine Svalbard reindeer (Rangifer tarandus platyrhynchus). Shape measurements were obtained combination fixed sliding semi-landmarks, was estimated...
