Evolutionary processes in marine plankton have been assumed to be dependent on the oceanic circulation system, which transports plankton between populations in marine surface waters. Gene flow facilitated by oceanic currents along longitudinal gradients may efficiently impede genetic differentiation of pelagic populations in the absence of confounding marine environmental effects. However, how ...

Optimum concentrations of anesthetic clove oil and anesthetic lidocaine-HCl were determined for a species of adult marine medaka, Oryzias dancena, over a range of salinity conditions, and investigated in a transport simulation experiment by analyzing various water and physiological parameters. Research indicated that the higher the concentration of anesthetic at each salinity, the shorter the a...

Marine organisms modify the distribution of radioisotopes in the oceanic ecosystem. Various vital processes of plants and animals concentrate elements. The distributions of the biota are often independent of their watery environment; they may actively migrate vertically or horizontally or may remain in place while the water moves past them. In the case of plankton, the concentrating organisms p...

Considering the complication of shipping techniques, high mobility of cargoes and poor condition and uncertainty during the voyage, there are numerous risks in the transportation process. With the burgeoning of shipping volumes, the occurrence of accidents and disruptive events could bring huge losses. Despite of regulatory control such as the establishment of International Safety Management (I...

Oil pollution is in the forefront ofpublic attention because of the recent series of oil spills from tankers such as the Argo Merchant. Oil spillage frequently destroys the marine flora and fauna; the most striking single effect is the oiling of large numbers of marine birds. For example, as many as 30,000 birds died after the grounding of the Torrey Canyon at Seven Stones Reef, Great Britain i...

Marine transportation is considered to be one of the most important aspects global services. Due increase in marine transportation, there are significant impacts on environment. One possible measures for mitigation environmental impact could switching environmentally friendly fuel. However, alternative fuel selection process a problem due various criteria and stakeholders that should involved p...

in order to improve the level of intelligence, availability, being on demand, convenience, information and humanization of rural public transportation systems, they are more willing to use modern information and communicative technologies. in addition to management services, intelligent transportation systems can provide passengers, drivers, travel agencies and other institutions with other ser...

Experiences of migratory species in one habitat may affect their survival in the next habitat, in what is known as carryover effects. These effects are especially relevant for understanding how freshwater experience affects survival in anadromous fishes. Here, we study the carryover effects of juvenile salmon passage through a hydropower system (Snake and Columbia rivers, northwestern United St...
