Interspecific variation in UV defense mechanisms among temperate freshwater fishes.
An important step in predicting the effects of future increases in UV radiation (UVR) is to evaluate the mechanisms that organisms use to prevent and repair DNA damage and determine how those mechanisms influence UVR sensitivity. Damage is prevented to varying degrees through photoprotection and repaired via two main pathways: nucleotide excision repair and photoenzymatic repair. At present, li...
متن کاملSpeciation in Freshwater Fishes
The extraordinary species richness of teleost fishes has attracted much research on mechanisms and modes of speciation. We here review research on speciation in freshwater fish in light of speciation theory, and place this in a context of knowledge about broad-scale diversity patterns in freshwater fishes. We structure our review around the major axes of divergence during speciation in freshwat...

متن کاملendemicity in the freshwater fishes of iran
iran contains 33 named endemic fish species, which together with undescribed taxa, approximates one-third of the ichthyofauna. endemism in relatively large species such as fishes, which are better known systematically than other taxa, can often serve to indicate areas in need conservation. an analysis of endemicity is given in terms of systematics, distribution and ecology.
