Today the future supply of seafood is threatened due to human activities which, among other things, has led to overfishing. However, more environmental friendly initiatives of producing seafood have emerged, such as Recirculating Aquaculture Systems (RASs). By analyzing the sensitivity analysis from six different Life Cycle Analysis (LCAs) on RASs, eight different factors that influence the enviro
This study was done to gain an understanding of the importance of 12 water sources that are in the Vomb biosphere reserve. To do so, an ecosystem services analysis that included the four following types of ecosystem services: provisioning, supporting, regulating, and cultural services, was conducted. The ecosystem services analysis was done by using indicators for each service. A final score base
Shoreline protection is, along with general habitat protection, the only directly applicable conservation act for shorelines in Sweden. The purpose of shoreline protection is to safeguard the public’s recreational access to shoreline areas and protect flora and fauna. Sweden has had general shoreline protection since 1975, and in many municipalities the shoreline protection is extended. Svedala mu
It has been previously shown that an increase in the relative value of tea increases female survival rate by enhancing their economic value. By combining contemporary district-level census data with historical data on tea production, in this paper I examine whether contemporary regional variations in gender disparities across India can be traced back to the tea production induced by the British Ea
The purpose of this study is to investigate how and to what extent four different sustainability certifications set standards for conserving or promoting biodiversity. This is of importance since there are a large number of certifications of different kinds on the market and as a consumer it can be difficult to navigate among these. How these certifications favor biodiversity is important to inves
Climate change, the energy crisis of 2022-2023, and estimations of future electricity demands have stressed the necessity for a rapid transition of the energy system. Offshore wind energy plays an important role in this transition, and is expected to expand considerably on a global level, in the EU and in Sweden. While Swedes show high support of wind energy, a majority of recent projects have bee
Food production is a major driver of climate change and environmental degradation. There is a political will to use public procurement as a strategic tool to promote more sustainable practices in the food industry. There are many aspects of sustainable food consumption, and one aspect that is getting increased attention is locally produced food. This study aims to examine how municipalities in the
The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. Detrimental effects of competition can result where co-existing species exhibit a high degree of shared resource use (i.e., niche overlap). Th
An alternative formulation of the Lund fragmentation model for string states without gluons is presented. It is shown that the fragmentation process can be factorised into a product of transition operators with well-defined eigenfunctions and corresponding eigenvalues. The physical properties of these functions are studied and possible applications are suggested. A fragmentation model for multigl
This paper focuses on future scenarios of demand and supply of grain in China. Economic development has been growing at a steady pace for decades and there are no signs of a decline in the near future. Projections of population trends show that the population will continue to expand until 2050, when a levelling- off is predicted. The growth of both population and economy drives industrialisation a
A new fragmentation model for multigluon strings is presented
Over the past 30 years a vast number of studies have demonstrated the presence of pharmaceutical residues in the environment. But still knowledge is scarce regarding the interaction of these emerging pollutants with various matrices in nature. A chromatographic system with on-line detection was devel- oped to perform a sorption study of six selected pharmaceuticals to four natural sediments and de
Fish are more sensitive to introduced disturbances from synthetic endocrine disrupting compounds during early life phases compared with mature stages. 17α-Ethinylestradiol (EE2), which is the active compound in human oral contraceptives and hormone replacement therapies, is today ever present in the effluents from sewage treatment plants. EE2 targets and interacts with the endogenous biological sy
Ancient DNA trapped in the matrices of ceramic transport jars from Mediterranean shipwrecks can reveal the goods traded in the earliest markets. Scholars generally assume that the amphora cargoes of 5th-3rd century B.C. Greek shipwrecks contained wine, or to a much lesser extent olive oil. Remnant DNA inside empty amphoras allows us to test that assumption. We show that short 100 nucleotides of an
Estrogen receptors (ers) not only are activated by hormones but also interact with many human-derived environmental contaminants. Here, we present evidence for four expressed er genes in Atlantic salmon cDNA - two more ers (erα2 and erβ2) than previously published. To determine if er gene expression differs between two adult life-stages we sampled 20 adult salmon from the feeding phase in the Balt
Monte Carlo simulation is a useful technique to propagate uncertainty through a quantitative model, but that is all. When the quantitative modelling is used to support decision-making, a Monte Carlo simulation must be complemented by a conceptual framework that assigns a meaningful interpretation of uncertainty in output. Depending on how the assessor or decision maker choose to perceive risk, the
The response of the terrestrial water cycle to global warming is central to issues including water resources, agriculture and ecosystem health. Recent studies indicate that aridity, defined in terms of atmospheric supply (precipitation, P) and demand (potential evapotranspiration, E p) of water at the land surface, will increase globally in a warmer world. Recently proposed mechanisms for this res
We describe the process of building a climate service centred on regional climate model results from the Rossby Centre regional climate model RCA4. The climate service has as its central facility a web service provided by the Swedish Meteorological and Hydrological Institute where users can get an idea of various aspects of climate change from a suite of maps, diagrams, explaining texts and user g
The price gap between West Texas Intermediate (WTI) and Brent crude oil markets has been completely changed in the past several years. The price of WTI was always a little larger than that of Brent for a long time. However, the price of WTI has been surpassed by that of Brent since 2011. The new market circumstances and volatility of oil price require a comprehensive re-estimation of risk. Therefo
The US Endangered Species Act (ESA) regulates what landowners, land managers, and industry can do on lands occupied by listed species. The ESA does this in part by requiring the designation of habitat within each listed species’ range considered critical to their recovery. Critics have argued that critical habitat (CH) designation creates significant economic costs while contributing little to spe
