Ecology, Engineering, and Economics

Abstract There appears to be increasing evidence that contemporary social and environmental problems and energy shortage are symptomatic of prebreakdown stresses inherent in the technical and socioeconomic organization of our system of production and consumption processes as it evolved under the “explosive” force of the industrial revolution. In an effort to understand these stresses and [...]

Ecology, Aquaculture and Space Colonies

Abstract Recent research results show that very small autotrophic/heterotrophic assemblages open to energy but totally isolated from exchanges of matter with external systems persist for years and probably indefinitely. General and specific ecological thermodynamic hypothesis for the behavior of such systems have been proposed and are being tested. Meanwhile, the National Aeronautics and Space Administration [...]

A Concept in Adaptive Ecosystem Management – An engineering perspective

Abstract Uncertainty how ecosystems will behave and look like in the future has been increasing. Several concepts, such as sustainable, adaptive, or risk-based management, were proposed to cope with uncertain, incomplete knowledge, and with changing environmental conditions. However, there is a lack of agreement what those concepts mean and how they differ from traditional forest [...]

Recent advances in biosensor techniques for environmental monitoring

Abstract Biosensors for environmental applications continue to show advances and improvements in areas such as sensitivity, selectivity and simplicity. In addition to detecting and measuring specific compounds or compound classes such as pesticides, hazardous industrial chemicals, toxic metals, and pathogenic bacteria, biosensors and bioanalytical assays have been designed to measure biological effects such as cytotoxicity, [...]

Unearthing human pathogens at the agricultural–environment interface: A review of current methods for the detection of Escherichia coli O157 in freshwater ecosystems

Abstract Contamination of water with the zoonotic pathogen Escherichia coli O157 can have severe public health implications and has led to many large disease outbreaks. Although the gastrointestinal tract of ruminants is the recognised reservoir of this organism, E. coli O157 can persist for significant periods of time in animal manure and contaminated soil, from [...]

Prospects for combining chemical and biological methods for integrated environmental assessment

Abstract …Besides deploying a chemicals-driven strategy for the ecological risk assessment of the pollutants, it is necessary to apply and to explore biological strategies. Consequently, bioassays, biosensors and effect-directed analysis (EDA) to identify pollutants responsible of particular effects have become increasingly important. We give a broad overview of how to assess biological monitoring of ecosystems [...]

Biosensors for Environmental Monitoring at Global Scale and the EU Level

Abstract Biosensor technology is based on a specific biological recognition element in combination with a transducer for signal processing. Since their inception, biosensors have been expected to play a significant analytical role in environmental monitoring…biomonitoring is an essential tool for rapid and cost-effective environmental monitoring. For this reason, biosensor technology has been considered as a [...]
