Microbial diversity and ecological networks as indicators of environmental quality
Environmental Chemistry Letters, 2017Evaluating the quality of ecosystems in terms of biological patrimony and functioning is of critical importance in the actual context of intensified human activities. Microbial diversity is commonly used as a bioindicator of ecosystems functioning. However, there is a lack of sensitivity of microbial diversity indicators in the case of moderate and ...

Lake water environmental problems caused by lake shrinkage in semiarid zones have attracted widespread attention, but few studies have quantified the impact of lake shrinkage on the terrestrial ecological environmental quality of watersheds. In this study, remote sensing image inversion, digital elevation modeling, and statistical analysis were applied

AbstractThe recently derived Dutch Environmental Quality Standards (EQS) for water, soil, and sediment for approximately 170 substances have been evaluated. Three methods have been used to derive the Dutch EQS. Independent of how the EQS were derived, they are given equal weight in Dutch environmental policy.

Both benign and harsh environments promote the evolution of sociality. This paradox-societies occur in environments of such contrasting quality-may be explained by the different types of benefits that individuals receive from grouping: resource defense benefits that derive from group-defended critical resources versus collective action benefits that ...

Modelling of soil environmental quality and early warning of integrated ecological risk
Environmental PollutionThe knowledge of dynamic trend in soil heavy metal contamination and associated risk is important for soil pollution prevention, safe utilization and early warning of soil environmental quality and ecological risk. In this study, a modified integrated risk index (NIRI) was adopted to evaluate ecological risk in agricultural soil in Wenzhou with 70 ...

Model of assessment of influence of ecological investments upon environmental quality [PDF]
The Problems of Economy, 2013 The article justifies non-efficiency of the existing system of financing environment protection measures and expediency of use of specialised economic and mathematical tools of support of managerial decisions with respect to volumes of investing into the nature protection sphere.

The impact of environmental quality on mental health: an ecological study
Journal of Public Mental HealthPurpose A growing body of research suggests that exposure to natural environments has several mental health effects. This paper aims to evaluate whether countries with high-quality environments report fewer mental health disorders. Design/methodology/approach This study uses secondary data from the Legatum Centre for National Prosperity.

Visual and Ecological Environmental Quality Model for Transportation Planning and Design
Transportation Research Record: Journal of the Transportation Research Board, 1996Landscape aesthetics and environmental quality have both become central investigatory areas in transportation planning and design. Environmental designers are interested in applying research-based models to study the effects of specific transportation design treatments on the built and natural landscape.
