Although there is increasing use of eco-labeling, conditions under which eco-labels can command price premiums are not fully understood. In this article, we demonstrate that the certification of environmental practices by a third party should be analyzed as a strategy distinct from—although related to—the disclosure of the eco-certification through a label posted on the product. By assessing ec...

Aquaponics is one of the recirculating aquaculture systems in which plant grows without soil. Considering the lack of information about aquaponic culture for main crops like pepper and the absence of comparison of plant conditions in soilless culture, in this experiment eco-physiological characteristics of pepper in hydroponics and aquaponics were investigated. After starting the plants to flow...

This paper studies aquatic ecological±economic systems such as the Chesapeake Bay. The stability of such eco-logical±economic systems depends on the successful functioning of a small number of generalist species in a wide range of ecological and economic conditions. We ®rst characterize the persistence of such systems. We then analyze the dynamic and the stochastic aspects of the resource alloc...

Acknowledging and understanding the role that information may play in affecting consumer assessment of eco-marketed products is a key step in improving the effectiveness of eco-labeling initiatives. Consumers who hold preferences for environmentally preferred products may be unable to express their preferences for such goods under current eco-information campaigns. The emerging use of eco-label...

Recently, our modern society demands the portable electronic devices such as mobile phones, laptops, smart watches, etc. Such devices demand light weight, flexible, and low-cost energy storage systems. Among different energy storage systems, supercapacitor has been considered as one of the most potential energy storage systems. This has several significant merits such as high power density, lig...

Recent studies of the joint dynamics of ecological and evolutionary processes show that changes in genotype or phenotype distributions can affect population, community and ecosystem processes. Such eco-evolutionary dynamics are likely to occur in modern humans and may influence population dynamics. Here, we study contributions to population growth from detailed genealogical records of a contemp...

Ecological development or 'eco-devo' examines the mechanisms of developmental regulation in real-world environments, providing an integrated approach for investigating both plastic and canalized aspects of phenotypic expression. This synthetic discipline brings a current understanding of environmentally mediated regulatory systems to studies of genetic variation, ecological function and evoluti...

There is growing recognition that a synergistic integration of data, knowledge, and methods from a variety of water-allied disciplines is needed to study, engineer for, or manage water resources. This integrated approach is necessary if we are to consider all components of the water cycle and their complex interactions with ecological, biogeochemical and human systems at a watershed-scale. The ...

Biodiversity and its responses to environmental changes are central issues in ecology and for society. Almost all microbial biodiversity research focuses on "species" richness and abundance but not on their interactions. Although a network approach is powerful in describing ecological interactions among species, defining the network structure in a microbial community is a great challenge. Also,...
