Clinical experiences indicate that aquatic exercises may have advantages for osteoarthritis patients. The purpose of this study was to examine the effects of aquatic exercise training on the knee pain and its symptoms as well as on the motor performance associated with daily living activities (ADL), sport-recreational activities, and the quality of life in men over 50. 30 men over 50 years ol...
A series of legal decisions culminated in 2002 with the California State Water Resources Control Board funding the San Francisco Estuary Institute to develop and implement a 3-year monitoring program to determine the potential environmental impacts of aquatic herbicide applications. The monitoring program was intended to investigate the behavior of all aquatic pesticides in use in California, t...
~ Organic matter from aquatic and terrestrial sources provides the carbon energy that 'drives' aquatic food webs. Most streams and rivers are heterotrophic — that is, more carbon is consumed (e.g. by animals and bacteria) than is produced within the system by aquatic plants. However, despite the presence of vast amounts of carbon in streams and rivers, only a small proportion of the total is tr...
Fish are the largest class of vertebrates, with over 25,000 estimated species and subspecies. Fish have evolved unique anatomical and physiological adaptations, when compared to terrestrial vertebrates, for life in a range of aquatic environments. Interest in aquatic animal health has been recorded in Eastern and Western cultures for more than 2,000 years. In recent times, there has been an inc...
Insects with over 30,000 aquatic species are known as very successful arthropods in freshwater habitats. Some of them are applied as biological indicators for water quality control, as well as the main food supply for fishes and amphibians. The faunistic studies are the basic step in entomological researches; the current study was carried out emphasizing on the fauna of aquatic insects in Karaj...
Australia is free from many significant diseases of aquatic animals.
