The neritic region of the Chaoshan plain is located on northeastern (NE) boundary South China Sea (SCS). Despite extensive research stratigraphic architecture and sedimentary processes within plain, neighboring area remains largely unexplored. In this study, we provide a new set ages seventeen quartz optically stimulated luminescence (OSL) dating results from four cores (SY2-2, SY3-1, SY3-2, HS...
Ten species of cetaceans coexist in the Mediterranean Sea, one richest seas biodiversity and endemisms worldwide. The conservation status has been a concern for many years, particularly due to increasing anthropogenic threats such as global warming overfishing. We established stable isotopic niches carbon, nitrogen, sulphur five inhabiting northwestern Sea elucidate mechanisms coexistence. fin ...
We report an investigation of the effects of increases in pCO2 on the survival, growth and molecular physiology of the neritic amphipod Gammarus locusta, which has a cosmopolitan distribution in estuaries. Amphipods were reared from juvenile to mature adult in laboratory microcosms at three different levels of pH in nominal range 8.1– 7.6. Growth rate was estimated from weekly measures of body ...
Bacterioplankton abundance (BA) and biomass (BB) from the eutrophic Pearl River Estuary (PRE) to the oligotrophic northern South China Sea (NSCS) were studied in the wet season. BA was significantly higher (p < 0.05) in PRE (12.51 ± 3.52 x 10⁸ cells L⁻¹), than in the continental shelf neritic province (CSNP, 4.95 ± 2.21 x 10⁸ cells L⁻¹) and in the deep oceanic province (OP, 3.16 ± 1.56 x 10⁸ ce...
This study investigated 14 trace elements (Ag, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, V and Zn) in the tissues of the giant squid Architeuthis dux from the Mediterranean and Atlantic Spanish waters. As for other families of cephalopods, the digestive gland and the branchial hearts of Architeuthis showed the highest concentrations of Ag, Cd, Co, Cu, Fe, Ni, Se, V and Zn, highlighting their ...
Ocean acidification and decreasing seawater saturation state with respect to calcium carbonate (CaCO3) minerals have raised concerns about the consequences to marine organisms that build CaCO3 structures. A large proportion of benthic marine calcifiers incorporate Mg into their skeletons (Mg-calcite), which, in general, reduces mineral stability. The relative vulnerability of some marine calcif...
Marine turtles undergo dramatic ontogenic changes in body size and behavior, with the loggerhead sea turtle, Caretta caretta, typically switching from an initial oceanic juvenile stage to one in the neritic, where maturation is reached and breeding migrations are subsequently undertaken every 2-3 years. Using satellite tracking, we investigated the migratory movements of adult females from one ...
Estimates of instantaneous mortality rates (Z) and annual appar ent survival probabilities (Φ) were generated from catch-curve analyses for oceanic-stage juvenile loggerheads (Caretta caretta) in the waters of the Azores. Two age distributions were analyzed: the “total sample” of 1600 log gerheads primarily captured by sight ing and dipnetting from a variety of vessels in the Azores between ...
