The American Naturalist, 2020
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 ...

The role of ecological-hygienic monitoring in the management of environmental quality
Fundamental and Experimental Biology, 2015The questions on the ecological projects with use of methodology of an estimation of risk and economic efficiency are surveyed at acceptance of the decisions about unhealthy industrial emissions. Thus it is necessary to give attention to systems of long-term observations including: research of spatial — temporary distribution of chemical substance ...

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 ...

An approach to a methodology for ecological valuation of environmental quality
WIT Transactions on Ecology and the Environment, 2008In Colombia territory planning depends on the natural resources on offer. Due to this offer and environmental quality, the most convenient uses of ground are fixed to satisfy the social demand, and the ecosystem sustainability. Often, natural resource quality valuation is managed from an analytical view, because it considers the natural environment as ...

Environmental Toxicology and Chemistry, 2001
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.

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 ...
