Human presence and activity in tropical forest is thought to exert top-down regulation over the various ‘green-world’ pathways of plant-based foodwebs. However, these effects have never been explored for the ‘brown-world’ pathways of fecal-detritus webs. The strong effects of humans on tropical game ...
In the offshore wind energy sector, there are many different conceptual wind turbine structures, from traditional mono-pile structures to floating platforms. The management of Reliability, Availability, Maintainability, and Safety (RAMS) issues is essential as early as possible at the beginning of the ...
Background We test whether traditional ecological knowledge (TEK) about how to make an item predicts a person’s skill at making it among the Tsimane’ (Bolivia). The rationale for this research is that the failure to distinguish between knowledge and skill might account for some of the conflicting results ...
A propulsion mechanism using a bio-inspired oscillating elastic fin has advantages for resolving problems regarding environmental and safety issues on the use of the screw propeller, namely, the entanglement of fishing nets or algae, the disturbance of mud that pollutes the water, and the danger to ...
Background Competition between bacteria for habitat and resources is very common in the natural environment and is considered to be a selective force for survival. Many strains of the genus Pseudoalteromonas were confirmed to produce bioactive compounds that provide those advantages over their competitors. ...
Shrimp is one of the most popular seafoods worldwide, and its lipids have been studied for biological activity in both, muscle and exoskeleton. Free fatty acids, triglycerides, carotenoids, and other lipids integrate this fraction, and some of these compounds have been reported with cancer chemopreventive ...
The salmon louse (Lepeophtheirus salmonis (Krøyer, 1837)) is a parasitic copepod that can, if untreated, cause considerable damage to Atlantic salmon (Salmo salar Linnaeus, 1758) and incurs significant costs to the Atlantic salmon mariculture industry. Salmon lice are gonochoristic and normally show ...
The use of static indicator species, in which species are expected to have a similar sensitivity or tolerance to either natural or human-induced stressors, does not account for possible shifts in tolerance along natural environmental gradients and between biogeographic regions. Their indicative value ...
Abstract The hydrocarbon basins in the Arctic are thought to hold a significant proportion of the world’s remaining undiscovered hydrocarbon reserves. Exploration in the region has been taking place for almost a century, with more that 500 wells drilled offshore and many thousands onshore, and will ...
Abstract In this paper an analysis of the selection of integrated template structures for the arctic environment is presented. First of all, an analysis of several actual projects has been carried out, where their specifics were thoroughly studied. One of the important parts of the work was devoted ...
Abstract This paper presents Alaska as a case study for evaluating the impact of non-technical risk on oil and gas exploration and development in the Arctic. Stakeholder relationships, regulatory uncertainty, government funding, listing species under the Endangered Species Act, cumulative impacts, ...
Abstract Active exploration of gas, oil and fish resources of Baltic, Barents, White, Japanese and Okhotsky seas leads to constant increase of anthropogenic pressure on costal and surrounding shelf areas. Development of coastal infrastructure, growth of freight traffics thought northern routes, including ...
Prioritizing efforts for conserving rare and threatened species with limited past data and lacking population estimates is predicated on robust assessments of their occupancy rates. This is particularly challenging for elusive, long-lived and wide-ranging marine mammals. In this paper we estimate trends ...

Exploration in the region has been taking place for almost a century, with more that 500 wells drilled offshore and many thousands onshore, and will ...
Muscle fiber size is activity-dependent and clinically important in ageing, bed-rest, and cachexia, where muscle weakening leads to disability, prolonged recovery times, and increased costs. Inactivity causes muscle wasting by triggering protein degradation and may simultaneously prevent protein synthesis. ...

Abstract Drilling and producing in high latitude environments is unforgiving. Temperatures often drop below -20°C and can reach as low as -50°C. Isolated locations or vast distances, extreme weather conditions and periods of deep darkness can restrict transportation of personnel and equipment. As a ...
Background Genomic selection can increase genetic gain within aquaculture breeding programs, but the high costs related to high-density genotyping of a large number of individuals would make the breeding program expensive. In this study, a low-cost method using low-density genotyping of pre-selected ...
