coastal and open Pacific Ocean. They also demonstrated that the flux of particles out of the surface layer, as measured by sediment traps, generally approximated the large-scale rate of new production. In 1967, Richard Dugdale and John Goering had defined new production as the fraction of the overall net primary production that was supported by external, or “new” inputs of nutrients. They focus...

The Federal Aviation Administration (FAA) Telecommunications Infrastructure (FTI) network is an essential component for the day-to-day FAA mission. In this digital era where quick access to information is essential, the FTI network has grown significantly and is used to transport data, services, and information for the National Airspace System (NAS). Whether the follow-on network FTI-2 is compl...

the anopheles stephensi mysorensis originating from kazeroon area south of iran, which had been maintained at the laboratory conditions of at 70% relative humidity for almost 150 generations, were subjected to cytogenetical analyses. the ‘instant’ landmarks in the squash preparations of the salivary gland chromosomes are indicative of cytotaxonomic characteristics of the species. the characteri...

The Bay of Biscay (northeast Atlantic) is an open marine ecosystem of particular concern in current European environmental policies. Indeed, it supports both a high biological diversity and numerous anthropogenic activities such as important fisheries. For the first time, stable isotope analyses (SIA) of carbon and nitrogen and analysis of total mercury (T-Hg) concentrations in the muscle (edib...
