Aquatic ecoregions were increasingly used as spatial units for aquatic ecosystem management at the watershed scale. In this paper, the principle of including land area, comprehensiveness and dominance, conjugation and hierarchy were selected as regionalizing principles. Elevation and drainage density were selected as the regionalizing indicators for the delineation of level I aquatic ecoregions...

BACKGROUND Strengthening exercises for the scapular muscles are used in the treatment of scapulothoracic dysfunction related to shoulder injury. In view of the intermuscular and intramuscular imbalances often established in these patients, exercises promoting lower trapezius (LT), middle trapezius (MT), and serratus anterior (SA) activation with minimal activity in the upper trapezius (UT) are ...

Transitions between aquatic and terrestrial environments are significant steps in vertebrate evolution. These transitions require major changes in many biological functions, including food uptake and transport. The Alpine newt, Ichthyosaura alpestris, is known to show a 'multiphasic lifestyle' where the adult shifts from a terrestrial to an aquatic lifestyle and then back to a terrestrial lifes...

background: copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. methods: in this study, juvenile species of silver carp with average weight of 200gr w...

abstract introduction: since balance maintenance is one of the indices of determining independence in older people, identifying factors that have some effects on it appears to be an interesting research issue. the aim of this study was to compare the effects of aquatic training; mental training and concurrent training (both aquatic and mental training) on balance in normal elderly males. materi...

the distribution and abundance of high aquatic plants in the gorganroud river was examined at five stations in four seasons (20 samples) over one year period during 2009-2010. we identified 21 species of aquatic plants from 21 genera, belonging to 9 families. these species were determined as 3 halophytic species (14.2%) and 18 high aquatic plants (85.7%).the highest species diversity was observ...
