Three studies demonstrated that avoidance personal goals are positively related to physical symptom reports. These results were obtained (a) using both longitudinal and retrospective methodologies and (b) controlling for neuroticism and other alternative predictor variables. In 2 of the studies, a process model was validated in which perceived competence and perceived controlledness were shown ...
Freeman-Sheldon syndrome (FSS) is a rare inherited form of distal arthrogryposis characterized by craniofacial deformities, camptodactyly with ulnar deviation of the fingers, and talipes equinovarus. Less than hundred cases have been reported till 2010 [1-3]. Multiple surgical interventions are needed to provide an acceptable quality of life. Anesthetic complications occur commonly [4, 5]. We p...
Forests are biologically diverse systems, representing some of the richest biological areas on Earth. They offer a variety of habitats for plants, animals and micro-organisms. However, forest biodiversity is increasingly threatened as a result of deforestation, fragmentation, climate change and other stressors. Biodiversity is the variation of life forms within a given ecosystem, biome, or on t...
The depletion of forest in developing countries due to extended pastures, agricultural land, fuel wood and etc. is a serious concern. Therefore planting trees for reforestation and extended forest area is a essential assignment. Forest plantation with a basic criterion affects to understory plant diversity. This effects may make some species absent or appear. The objective of this study is to a...
Evenness is a key measure of community structure. Here, we examine the relationship between evenness and size-abundance distributions for both individuals and species using data gathered from Amazonian fish assemblages. We show that evenness increases as the fraction of numerically abundant species in larger body-size classes rises. As any processes that enable larger bodied species to increase...
The present study concerns seasonal variations, correlation coefficient and biodiversity indices of zooplanktons during January-December, 2008 in the Harsool-Savangi dam, Aurangabad, India. A total of 25 genera were recorded of which 10 were Rotifers, 8 Cladocerons, 5 Copepods and 2 Ostracods.
