The Norwegian research vessel “Dr. Fridtjof Nansen” operating under United Nations flag, conducted four surveys in the waters of Sri Lanka from 1978 – 2018. During the three first surveys carried out annually in 1978 - 1980, a total fish abundance of about 280 000 – 395 000 tons were measured by fisheries acoustics. From the first two surveys signals of potential increases in catches by a factor of two, and use of longlining f...
This study evaluates the environmental impacts of producing mannosylerythritol lipids (MELs) using life cycle assessment (LCA) and kinetic models. MELs are microbial biosurfactants with various applications produced from biobased sources. The LCA results indicate that substrate provision, bioreactor aeration and solvent use for purification are major environmental impact sources. The findings highlight areas for improving the...
A Murky Ruling Threatens the Fate of Millions of US WetlandsNARA Subscribed
For decades, federal protections were extended to wetlands adjacent to “waters of the US” by the Clean Water Act. In its Sackett v. EPA ruling, however, the US Supreme Court redefined the meaning of “adjacent,” eliminating protections to wetlands without a continuous surface connection to these waters (i.e., geographically isolated wetlands, GIWs). Yet it remains unclear how this continuous surface test will work in reality, w...
A review of new and existing non-extractive techniques for monitoring marine protected areasOA Marine
Ocean biodiversity loss is being driven by several anthropogenic threats and significant efforts are required to halt losses and promote healthy marine ecosystems. The establishment of a network of Marine Protected Areas (MPAs) can help restrict damaging activities and have been recognised as a potential solution to aid marine conservation. When managed correctly they can deliver both ecological and socio-economic benefits. In...
Rationale One hallmark of addiction is an altered neuronal reward processing. In healthy individuals (HC), reduced activity in fronto-striatal regions including the insula has been observed when a reward anticipation task was performed repeatedly. This effect could indicate a desensitization of the neural reward system due to repetition. Here, we investigated this hypothesis in a cohort of patients with alcohol use disorder (A...
Global population projections foresee the biggest increase to occur in Africa with most of the available uncultivated land to ensure food security remaining on the continent. Simultaneously, greenhouse gas emissions are expected to rise due to ongoing land use change, industrialisation, and transport amongst other reasons with Africa becoming a major emitter of greenhouse gases globally. However, distinct knowledge on greenhou...
The early marine distribution of Atlantic salmon in the North‐east Atlantic: A genetically informed stock‐specific synthesisNARA Subscribed
The survival of Atlantic salmon ( Salmo salar) , an increasingly rare anadromous species, has declined dramatically during its marine phase, with disproportionate impacts on the poorly understood early post‐smolt period. Logistical constraints on collecting oceanic data to inform this issue pose a formidable obstacle. To advance understanding of post‐smolt distributional ecology in the North‐east Atlantic, a comprehensive anal...
Accounting for multiple ecosystem services in a simulation of land‐use decisions: Does it reduce tropical deforestation?NARA Subscribed
Conversion of tropical forests is among the primary causes of global environmental change. The loss of their important environmental services has prompted calls to integrate ecosystem services (ES) in addition to socio‐economic objectives in decision‐making. To test the effect of accounting for both ES and socio‐economic objectives in land‐use decisions, we develop a new dynamic approach to model deforestation scenarios for tr...
Mannosylerythritol lipids (MEL) are microbial biosurfactants belonging to the class of glycolipids. They can be produced biotechnologically by smut fungi and have the potential to replace current chemical surfactant products, for example in household detergents or cosmetics. In this article, we highlight our latest research on the various producer organisms as well as the genetics and regulation of MEL biosynthesis, aiming for...
