The Endless Summer
People with metabolic syndrome and obesity are at an increased risk of mortality from cardiovascular disease. Over the past decade, there has been intensive research into new ways to stimulate weight loss to lower this risk. One of the key tissues is the metabolically active brown adipose tissue (BAT). Given that this is a thermogenic tissue, it can be stimulated by cold and is suggested by som...
متن کاملBiogeochemical Processes and Implications for Nutrient Cycling
The availability and cycling of nutrients is determined by an interaction of physical, chemical, and biological processes in an ecosystem. This interaction of processes, collectively known as biogeochemistry, is important as it determines the forms, transformations, and ultimate fate of nutrients in a given system. This chapter focuses on biogeochemical processes in springs and spring runs with...
متن کاملNutrient pressures and ecological responses to nutrient loading reductions in Danish streams, lakes and coastal waters
The Danish National Aquatic Monitoring and Assessment Programme (NOVA) was launched in 1988 following the adoption of the first Danish Action Plan on the Aquatic Environment in 1987 with the aim to reduce by 50% the nitrogen (N) loading and by 80% the phosphorus (P) loading to the aquatic environment. The 14 years of experience gathered from NOVA have shown that discharges of total N (TN) and P...
متن کاملNutrient Cycling in Lakes and Streams: Insights from a Comparative Analysis
Understanding of general ecosystem principles may be improved by comparing disparate ecosystems. We compared nutrien t cycling in lakes and streams to evaluate whether contrasts in hydrologic properties lead to differen t controls and differen t rates of in ternal nutrien t cycling. Our primary focus was nutrien t cycling that resu lts in increased productivity, so we quantified nutrien t cycli...
متن کاملBiogeochemistry of tropical lakes
Biogeochemical processes are driven jointly by mass flux and metabolism, but biogeochemical contrasts across latitude are more strongly related to metabolism than to mass flux. Metabolism can be expressed in terms of metabolic potential, which is regulated by temperature, irradiance, and chemical feedstocks (nutrients, electron acceptors, organic matter). Metabolic potential of autotrophs in tr...
