Abstract Antibiotic residues and antibiotic resistance genes (ARGs) have been found worldwide. Chloramphenicol, one of antibiotics, had been banned for its use in breeding industry in many countries. The status about chloramphenicol resistance genes (CRGs) in mangrove ecosystems is still unknown. In the present study, quantitative PCR was employed to investigate the abundance of CRGs. The residual determination of chloramphenicols was performed via ultra-high pressure liquid chromatography tande...
Abstract The hydrological and hydrodynamic response of Bohai Strait to an intense wind gust in the summer of 2016 was synthesized based on a 9-day in-situ observation at two mooring stations across the strait. At the north station, the sea level abnormally rose by 0.4 m during the wind gust. Strong subtidal inflow (into Bohai Sea) was observed during the gust, then changed to outflow after the gust subsided. At the southern station, the hydrographic property of water column changed rapidly with ...
Abstract Food web studies have provided insight into the dynamics of benthic ecosystems and their stability, stimulating research into the importance of different organic matters (OM) inputs in the ecological and metabolic processes that affect community structure. Using stable isotope analysis (SIA) and Bayesian ellipses, this study examines the influence of terrestrial OM and hydrographic conditions on food web structure and niche width in a glacial system (Baker/Martinez fjord complex). Two e...
Abstract Eurasian spoonbills (Platalea leucorodia) were first recorded breeding in the German Wadden Sea in 1995. Since then, the breeding numbers have been increasing. However, the foraging habitats and diet of spoonbills in this area remain largely unknown. We therefore analysed the foraging ecology of spoonbills from three colonies in this area using GPS telemetry and examined their diet based on regurgitates and stable isotope analysis. GPS logger data (2014–2016) implied that tidal creeks n...
Abstract Global warming is driving changes in the distribution patterns of many species, leading to a general tropicalization and meridionalization of biota. In this context, populations of some marine species are in regression while others are expanding their populations. Such is the case of benthic cnidarians belonging to the order Zoantharia and suborder Brachycnemina, whose populations are able to cause phase-shifts in coral reef ecosystems. Marine assemblages in the subtropical Canary Islan...
Abstract Sandy beaches are very dynamic and changeable environments that present a wide variety of life forms, and, in some areas, high productivity. In the Gulf of Valencia (Western Mediterranean Sea, Spain) these areas have endured an economically important shellfishery of clams (Donax trunculus and Chamelea gallina). In the Mediterranean, a sea with a notable oligotrophic character, rivers are particularly important because of the contributions of fresh water that carry nutrients and organic ...
Abstract The Spratly Islands archipelago in the South China Sea is a disputed marine area impacted by a destructive free-for-all race to resources. Though physically open, the archipelago is a semi-closed system because the flushing time scales are comparable to the pelagic larval duration of coral and reef fish larvae. Island-building, overfishing and destructive clam harvesting in the archipelago destroy, or at the very least severely damage, the directly impacted reefs. At these reefs, larvae...
Abstract Mangrove forests suffer from large-scale conversion into pond aquaculture worldwide. However, rarely can the detailed development of these changes and the consequences for coastal biogeochemistry be traced back to baseline conditions. We analyzed decadal changes in mangrove forest and aquaculture pond cover of five estuaries along the east coast of Hainan, northern South China Sea, using aerial photos and satellite images from 1966 to 2009. In addition, we reconstructed historical chang...
Abstract Mangrove forests provide many valuable services, including wave- and tidal-energy dissipation, sediment accumulation, and substrate stabilization. But, their global extent is rapidly shrinking. Sedimentary research that is needed to inform restoration projects has so far focused on characterizing flow patterns through forests associated with single rivers, nearshore environments, or terminating tidal channels. However, flows within the most extensive mangrove forests tend to be driven t...
