The Himalayan ecosystems, which are among the least studied mountain face threats and habitat degradation due to unplanned development, natural calamities, overgrazing. Ungulates like tahrs (Hemitragus jemlahicus), play a crucial role in ecology as it forms major prey base of top predators ecosystems. Objective: To explore population status, distribution, uses Lamtang National Park (LNP), Centr...

Argininosuccinic aciduria (ASA) is an autosomal recessive urea cycle disorder caused by deficiency of argininosuccinate lyase (ASL) with a wide clinical spectrum from asymptomatic to severe hyperammonemic neonatal onset life-threatening courses. We investigated the role of ASL transcript variants in the clinical and biochemical variability of ASA. Recombinant proteins for ASL wild type, mutant ...

MARCH 2004 AMERICAN METEOROLOGICAL SOCIETY | he Sierra Nevada Range is one of the most prominent and steepest mountain barriers in the United States and, not surprisingly, is a well-known location for a multitude of topographically forced atmospheric phenomena. As the prevailing westerly winds pass over the Sierra Nevada, gravity waves are frequently generated. Occasionally these mountain waves...

BACKGROUND Unlike developed countries, data from the developing world regarding motor developmental disorders is scarce. OBJECTIVES In the present study, we used the Infant Neurological International Battery (Infanib) test to determine the prevalence of motor impairment in 4-18 month-old infants in Alborz province, Iran, in 2010. PATIENTS AND METHODS This study was a descriptive-analytic st...

Oxidative stress is considered one of the main ecological and evolutionary forces. Several environmental stressors vary geographically and thus organisms inhabiting different sites face different oxidant environments. Nevertheless, there is scarce information about how oxidative damage and antioxidant defences vary geographically in animals. Here we study how oxidative stress varies from lowlan...

We used landscape genetics and statistical models to test how landscape features influence connectivity or create barriers to dispersal for a mountain riparian tree species, Euptelea pleiospermum. Young leaves from 1078 individuals belonging to 36 populations at elevations of 900-2000 m along upper reaches of four rivers were genotyped using eight nuclear microsatellite markers. We found no evi...

Climate change influences the distribution of species, causing the displacement of distribution areas, both in altitude and latitude. The potentially most climate change-susceptible taxa are those of mountain peaks, with limited distribution areas, such as rare or endemic species. In this paper, we deepened the study of Androsace mathildae Levier, a plant that lives in Central Italy over 2500 m...
