Fish species biodiversity of Dadin-Kowa reservoir: Current status

Bioaccumulation of mercury in some organs of two fish species from the Sanandaj Gheshlagh Reservoir, Iran

The purpose of this study was to monitor the concentrations of mercury in the edible muscle, gill, liver, and skin of common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix), in the Sanandaj Gheshlagh Reservoir, Iran. Mercury concentrations were assayed using Shimadzu AA 6600 atomic absorption spectrophotometer, and the results were given as µg/g wet weight. The level of mer...

3 . 11 Summary of Current Status of Oregon ’ s Biodiversity

Introduction Biodiversity, short for biological diversity, is the variety and variability of living organisms and the ecological complexes in which they live (Primack, 1993). One of the more widely accepted definitions (Noss and Cooperrider, 1994) extends the concept of biodiversity to include “the ecological and evolutionary processes that keep [these systems] functioning, yet ever changing an...

The current status of Pythium species in Iran: challenges in taxonomy

Pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. Some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. Since 1968, when the first Pythium species was reported from Iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

Beyond Biodiversity: Fish Metagenomes

Biodiversity and intra-specific genetic diversity are interrelated and determine the potential of a community to survive and evolve. Both are considered together in Prokaryote communities treated as metagenomes or ensembles of functional variants beyond species limits.Many factors alter biodiversity in higher Eukaryote communities, and human exploitation can be one of the most important for som...
