Although ravens were once widespread throughout Appalachia they are now considered threatened or endangered in many states of the region. We document a nesting pair of common ravens in an area of southeastern Kentucky nearly 50 km northwest of traditional nesting sites. Further, we suggest several factors that may have influenced the patterns of raven abundance in the state and offer management...

objectives: one of the issues that have consistently been the concern for the health affair specialists and cure and massive social governors in health fields is the rate of disorders prevalence, diseases and the related subjects to epidemiology. purpose of this study was to estimate the prevalence of mathematic disability amongst primary schools of karaj. methods: totally 432 students were sel...

The organization of energy metabolism was assessed in erythrocytes of the sea raven {Hemitripterus americanus). Cell suspensions displayed a potential for aerobic glycolysis, shown by the presence of the glycolytic enzymes phosphofructokinase, aldolase and pyruvate kinase and the mitochondrial markers citrate synthase and malate dehydrogenase. Rates of oxygen uptake {MQ^} and glucose uptake Mg\...

Antifreeze proteins lower the freezing point of their solution by binding to ice and inhibiting its growth. One of several structurally different antifreeze proteins in fishes (type II) is homologous to the carbohydrate-recognition domain of Ca2+-dependent lectins and adopts the same three-dimensional fold. Type II antifreeze proteins from herring and smelt require Ca2+ for binding to ice, wher...

Raven matrices are used for assessing fluid intelligence and the intellectual level of groups with low intelligence. Our study addresses qualitative analysis of information processing in Raven matrices performance among individuals with intellectual disability with that of their typically developed (TD) counterparts. Twenty-three adults with non-specific intellectual disability (NSID), 15 adult...

Widespread species that are morphologically uniform may be likely to harbour cryptic genetic variation. Common ravens (Corvus corax) have an extensive range covering nearly the entire Northern Hemisphere, but show little discrete phenotypic variation. We obtained tissue samples from throughout much of this range and collected mitochondrial sequence and nuclear microsatellite data. Our study rev...
