Science Journal for Kids is an online scientific journal that publishes adaptations designed for children and teens of academic research papers that were originally published in high-impact peer-reviewed journals, as well as science teaching resources for teachers.
Aquatic science is the study of the various bodies of water that make up our planet including oceanic and freshwater environments. [1] Aquatic scientists study the movement of water, the chemistry of water, aquatic organisms, aquatic ecosystems, the movement of materials in and out of aquatic ecosystems, and the use of water by humans, among other things.
Sea water is 827 times denser than air.. Due to the higher density of sea water (1,030 kg m −3) than air (1.2 kg m −3), the force exerted by the same velocity on an organism is 827 times stronger in the ocean.
The term limnology was coined by François-Alphonse Forel (1841–1912) who established the field with his studies of Lake Geneva.Interest in the discipline rapidly expanded, and in 1922 August Thienemann (a German zoologist) and Einar Naumann (a Swedish botanist) co-founded the International Society of Limnology (SIL, from Societas Internationalis Limnologiae).
Substrate is the earthy material that forms or collects at the bottom of an aquatic habitat. It is made of sediments that may consist of: . Silt – A loose, granular material with mineral particles 0.5 mm or less in diameter.
Freshwater biology is also used to study the effects of climate change and increased human impact on both aquatic systems and wider ecosystems. [4] Freshwater organisms, vertebrates especially, appear to be at a higher extinction risk from climate change than terrestrial or marine organisms.
Hydrobiology is the science of life and life processes in water. Much of modern hydrobiology can be viewed as a sub-discipline of ecology but the sphere of hydrobiology includes taxonomy, economic and industrial biology, morphology, and physiology. The one distinguishing aspect is that all fields relate to aquatic organisms.
The publication of the hypothesis was released later that same year under the title "The River Continuum Concept" in the Canadian Journal of Fisheries and Aquatic Sciences. [20] The concept built on the work of other American limnologists such as Ruth Patrick , from which the modern riverine ecosystem model has emerged, and Luna Leopold, which ...
