Qualitative status of the environment is signaled by a group of indicators, known as bioindicators, several of which are responsible for showing progressive impacts of different types of pollutants. Having addressed the influence of various bioindicators in environmental pollution, it has been revealed that bioindicators are sensitive to any disturbance in any environment. With regards to the p...

Background: Reviewing the reproductive health indicators (RHIs) provides the possibility of periodic health system performance evaluation to achieve balanced development. This study aimed to determine the trend of ten reproductive health indicators changes during 2002-2011, and examining their relationship with the Human Development Index (HDI). Methods: In this ecological study the trend of t...

Developing effective indicators of ecological condition requires calibration to determine the geographic range and ecosystem type appropriate for each indicator. Here, we demonstrate an approach for evaluating the relative influence of geography, geomorphology and human disturbance on patterns of variation in biotic indicators derived from multiple assemblages for ecosystems that span broad spa...
