Abstract. Continental shelf regions in the ocean play an important role global cycling of carbon and nutrients, but their responses to change are understudied. Global Earth system models (ESMs), as essential tools for building understanding biogeochemistry, used extensively routinely projections future climate states; however, relatively coarse spatial resolution is likely not appropriate accurately representing complex patterns circulation elemental fluxes on shelves along margins. Here, we...
Abstract Ocean circulation shapes marine phytoplankton communities by setting environmental conditions and dispersing organisms. In addition, processes acting on the water column (e.g., heat fluxes mixing) affect community structure modulating variables that determine in situ growth loss rates. Understanding scales over which vary time space is key to elucidate relative contributions of local ocean distributions. Using a global ecosystem model, we quantify temporal spatial correlation for...
Article AbstractObjective: Selective serotonin reuptake inhibitors (SSRIs) appear to be an effective class of medications for the treatment generalized anxiety disorder. Within SSRI class, however, there have been no comparative studies this Therefore, in present study, we compared efficacy and tolerability 2 SSRIs, paroxetine sertraline, Method: In parallel-group, double-blind, flexible-dose 55 patients with primary disorder (DSM-IV criteria) were randomly assigned receive either or...
Abstract The Southern Ocean is a region of intense air–sea exchange that plays critical role for ocean circulation, global carbon cycling, and climate. Subsurface chlorophyll‐a maxima, annually recurrent features throughout the Ocean, may increase energy flux to higher trophic levels facilitate downward export. It important model parameterizations appropriately represent chlorophyll vertical structure in Ocean. Using BGC‐Argo profiles Biogeochemical State Estimate (B‐SOSE), we investigate...
Abstract Ocean chlorophyll time series exhibit temporal variability on a range of timescales due to environmental change, ecological interactions, dispersal, and other factors. The differences in observed at stationary locations (Eulerian perspective) or following water parcels (Lagrangian are poorly understood. Here we contrasted the ocean these two observational perspectives, using global drifter trajectories satellite generate matched pairs Eulerian‐Lagrangian series. We found that for...
Abstract. Recent studies demonstrate that marine N2 fixation can be carried out without light by heterotrophic fixers (diazotrophs). However, direct measurements of in aphotic environments are relatively scarce. Heterotrophic as well unicellular and colonial photoautotrophic diazotrophs present the oligotrophic Gulf Aqaba (northern Red Sea). This study evaluates relative importance these different combining biogeochemical models with time series at a 700 m deep monitoring station Aqaba. At...
As pescarias de pequena escala ou artesanais desempenham um papel fundamental para a segurança alimentar e mitigação da pobreza na América Latina. Estas estão cada vez mais ameaçadas por fatores antropogênicos climáticos que atuam em diversas escalas espaço-temporais. Este trabalho documenta os efeitos variabilidade climática invertebrados Latina, com base literatura recente. Além disso, é discutido o impacto conjunto duas fontes adicionais: globalização dos mercados governança. Foi...
White-tip reef sharks are common inhabitants of the shallow waters surrounding Galapagos Islands, where several known aggregation sites have become touristic attractions. With aim to describe site fidelity and residency patterns white-tip in a saltwater creek, we used ultrasonic telemetry method. The study was undertaken channel South Academy Bay, Santa Cruz Island, from May 2008-September 2009. A total nine transmitters were attached receivers deployed at inner outside areas creek. From...
