The objective of this research was to identify and describe the different Ecological Species Groups (vegetation types) present in the Rural Heritage Museum of Guilan. The study area was approximately 260 ha, which is located in the Saravan Forest Park in Guilan province, north of Iran. Sampling procedure was performed with a systematic random technique. A total of 89 plots were sampled. Classif...
numerous ecological risk assessment methodologies have been developed over the last twenty years around the world for evaluating effects of pollutant on receptors such as different wildlife species. but so far such methods have only rarely been used to determine potential ecological risks in iran. therefore in this study we used one of these methodologies (eco-ssls) to determine ecological risk...

Many physical diseases have been reported to be associated with psychosocial factors. In these diseases, assessment relies mainly on subjective symptoms in natural settings. Therefore, it is important to assess symptoms and/or relationships between psychosocial factors and symptoms in natural settings. Symptoms are usually assessed by self-report when patients visit their doctors. However, self...
Ecological momentary assessment and/or experience sampling methods are increasingly used in health studies to study subjective experiences within changing environmental contexts. In these studies, up to 30 or 40 observations are often obtained for each subject. Because there are so many measurements per subject, one can characterize a subject's mean and variance and can specify models for both....
Bisphenol A (BPA) occurs widely in natural waters with both traditional and reproductive toxicity to various aquatic species. The water quality criteria (WQC), however, have not been established in China, which hinders the ecological risk assessment for the pollutant. This study therefore aims to derive the water quality criteria for BPA based on both acute and chronic toxicity endpoints and to...
pollination and pest control are perhaps the best-known ecological services performed by hover flies. the species diversity and their abundance have an influential impact on the ecological services provided by this family. to find out species diversity of adult flower flies associated with agroecosystems in kerman province, a biodiversity survey using insect net and color water traps was conduc...
Studies on avoidance of contaminants by aquatic organisms verified that such behavior may have crucial ecological implications. Yet, avoidance tests have not been considered in ecological risk assessments. This study aimed at developing a short-term test with Daphnia magna Straus based on avoidance of pulp mill effluents and at comparing its sensitivity to the standard 21 d D. magna reproductio...
