    Abstract Superoxide dismutase (SOD) protects plants from abiotic stress-induced reactive oxygen species (ROS) damage. Here, the effects of cadmium (Cd) exposure on ROS accumulation and SOD isozymes, as well as the identification of significant SOD isozyme genes, were investigated under different Cd stress treatments to Zhe-Maidong (

    Abstract One interesting question in the study of marine microbial ecology is how ocean currents affect the geographic distributions of microorganisms. The Zhe-Min Coastal Current (ZMCC) is strong in winter and could influence the plankton communities in Hong Kong coastal waters by bringing species from far north. In this study, we investigated the spatial distribution of microbial eukaryotic communities (MEC) in the ZMCC and evaluated the relative contribution of environmental and spatial factors on the variations of MEC. The results showed that diverse taxa of diatoms (Bacillariophyceae) and Dinophyceae (Dinoflagellata) dominated the sequences in all samples. MEC compositions in the Hong Kong coastal waters were closer to the communities in the ZMCC than other adjacent areas. Abundant and rare taxa exhibited a similar geographic pattern of distribution. Environmental factors alone explained 14.1% and 27.6% of the variations in the entire and abundant communities, respectively, which were higher than pure spatial factors (8.3% and 19.5%, respectively). The lower importance of spatial factors (dispersal limitation) might be explained by the passive dispersal favored by current transportation and was further supported by the high immigration rate computed in the neutral community model (NCM). High fitness to the NCM (R2 = 0.74) indicated the predominant role of neutral process in shaping the MEC. The large proportion of unexplained variations in rare taxa suggested the importance of other potential factors, especially biotic interactions. Our study demonstrates the influences of coastal current on local and regional structures of MEC.

    Abstract The temporal variation of sedimentary organic matters (SOM) in the East China Sea (ECS) is not fully assessed due to the complicated natural and anthropogenic processes. In this study, the compositions and distributions of multi-biomarker indicators (n-alkanes, n-alkanols and specific sterols) in a long sediment core collected from the Min-Zhe fined-grained sediment zone of the ECS were systematically studied to reveal variations of SOM sources and phytoplankton records over the last decades. The results of n-alkanes and sterols have demonstrated that terrestrial plants are the dominant SOM source, with the mean proportion of 67%. The temporal variation of terrestrial to marine biomarker ratios (TMBR) agree well with that of the dominant n-alkanes and terrigenous/aquatic ratios (TAR), suggesting that the multi-biomarker indicators yield a better assessment of the SOM source input. The regular variations of terrestrial OM and phytoplankton signals during the past decades record the interaction among marine ecological effects, anthropogenic activities and natural processes (i.e., extreme climate events). As a whole, the elevated productivity of marine phytoplankton since 1952 (mainly caused by enhanced nutrient inputs owing to the intensified human activities) and the decline in the period of 2005–2011 (likely influenced by the water impoundment of the Three Gorges Dam in 2003) were well reconstructed on the basis of brassicasterol (B) and dinosterol (D) indicators in this study. The B/(B + D) ratios also reveal the changes of community structure as a result of variations in the nutrient structure controlled by anthropogenic forcing. Notably, the anomalous peak in the abundance of n-alkanes with the even carbon predominance in about 1990 is identified for the first time, which may occur at that time of the first heavy rainfall after a long drought and is probably of the origin of biomass/fossil fuel combustion.

    Abstract Compositions and contents of sedimentary pigments were examined using high performance liquid chromatography in order to discuss the spatial distributions of phytoplankton primary production, phytoplankton functional type and the preservation efficiency of phytoplankton pigments and their influencing factors. The results showed that: chloropigments [Chlorins, including chlorophyll-a (Chl-a) and pheopigments (Pheo-a), such as pheophytin-a (PHtin-a), pheophorbide-a (PHide-a), pPheophytin-a (pPHtin-a), sterol chlorin esters (SCEs) and carotenol chlorin esters (CCEs)] were the major type of sedimentary pigments. The nutrients inputs from Changjiang Diluted Water and upwelling in the Zhe-Min coastal mud area were the major cause for the patchy distribution with high sedimentary chloropigment contents. Carotenoid contents showed no trending changes and exhibited high values in the Changjiang Estuary and Zhe-Min Coasts. Based on the relative proportions of each diagnostic carotenoid to the total diagnostic carotenoids in the sediments, the relative contributions of diatoms, dinoflagellates, prymnesiophytes, prasinophytes, cryptophytes and cyanobacterias in the phytoplankton fuctional types were 48.8% +/- 17.4%, 10.7% +/- 11.5%, 8.1% +/- 7.2%, 18.6% +/- 8.2%, 9.4% +/- 6.4% and 4.3% +/- 3.2%, respectively. The preference for external environmental conditions (e.g., nutrient level and water salinity) was the main cause for the decreasing trends of diatoms and dinoflagellates proportions and the increasing trends of prasinophytes, cryptophytes and cyanobacterias seawards. Based on the spatial distribution of Chl-a/Pheo-a ratios, the higher preservation efficiencies of sedimentary pigments in the coastal regions (e.g., outer edge of maximum turbidity zone in the Changjiang Estuary, mouth of the Hangzhou Bay and upwelling region in the Zhe-Min Coast) were mainly due to the higher sedimentation rate and seasonal occurrences of hypoxia in bottom water, and these regions with higher sedimentary pigment preservation efficiencies were probably ideal areas for the marine eco-environmental evolutions. The bad sedimentary environment caused by the water exchange inside and outside of Hangzhou Bay was the dominant reason for the low sedimentary pigment contents and preservation efficiencies in this region.
