Denitrification-nitrification process in permeable coastal sediments: An investigation on the effect of salinity and nitrate availability using flow-through reactors
Shan Jiang, Mark Kavanagh, Juan Severino Pino Ibánhez, Carlos Rocha
2021, 40(9): 1-12. doi: 10.1007/s13131-021-1811-5
Abstract:
Permeable coastal sediments act as a reactive node in the littoral zone, transforming nutrients via a wide range of biogeochemical reactions. Reaction rates are controlled by abiotic factors, e.g., salinity, temperature or solute concentration. Here,...
Estimating submarine groundwater discharge at a subtropical river estuary along the Beibu Gulf, China
Xilong Wang, Kaijun Su, Juan Du, Linwei Li, Yanling Lao, Guizhen Ning, Li Bin
2021, 40(9): 13-22. doi: 10.1007/s13131-021-1862-7
Abstract:
In certain regions, submarine groundwater discharge (SGD) into the ocean plays a significant role in coastal material fluxes and their biogeochemical cycle; therefore, the impact of SGD on the ecosystem cannot be ignored. In this study, SGD was estim...

Tectonic unit divisions based on block tectonics theory in the South China Sea and its adjacent areas
Zhengxin Yin, Zhourong Cai, Cheng Zhang, Xiaofeng Huang, Qianru Huang, Liang Chen
2021, 40(9): 33-42. doi: 10.1007/s13131-021-1898-8
Abstract:
Identifying distinct tectonic units is key to understanding the geotectonic framework and distribution law of oil and gas resources. The South China Sea and its adjacent areas have undergone complex tectonic evolution processes, and the division of t...
Copper and zinc isotope variations in ferromanganese crusts and their isotopic fractionation mechanism
Lianhua He, Jihua Liu, Hui Zhang, Jingjing Gao, Aimei Zhu, Ying Zhang
2021, 40(9): 43-52. doi: 10.1007/s13131-021-1775-5
Abstract:
Ferromanganese (Fe-Mn) crusts are potential archives of the Cu and Zn isotope compositions of seawater through time. In this study, the Cu and Zn isotopes of the top surface of 28 Fe-Mn crusts and 2 Fe-Mn nodules were analysed by MC-ICP-MS using comb...

Assessment of the exploitable biomass of thread herring (Opisthonema spp.) in northwestern Mexico
Marcelino Ruiz-Domínguez, Casimiro Quiñonez-Velázquez, Dana Isela Arizmendi-Rodriguez, Víctor Manuel Gómez-Muñoz, Manuel Otilio Nevárez-Martínez
2021, 40(9): 53-65. doi: 10.1007/s13131-021-1785-3
Abstract:
In recent years, the small pelagic fishery on the Pacific northwest coast of Mexico has significantly increased fishing pressure on thread herring Opisthonema spp. This fishery is regulated using a precautionary approach (acceptable biological catch ...
Estimating genetic parameters with molecular relatedness and pedigree reconstruction for growth traits in early mixed breeding of juvenile turbot
Song Sun, Weiji Wang, Yulong Hu, Sheng Luan, Ding Lyu, Jie Kong
2021, 40(9): 66-73. doi: 10.1007/s13131-021-1799-z
Abstract:
An introduced turbot population was used to establish families and to estimate genetic parameters of the offspring. However, there is a lack of pedigree information, and common environmental effects can be introduced when each full-sib family is rais...
The mitochondrial genome of Chaeturichthys stigmatias provides novel insight into the interspecific difference with Amblychaeturichthys hexanema
Jian Zheng, Bingjie Chen, Tianxiang Gao, Na Song
2021, 40(9): 74-81. doi: 10.1007/s13131-021-1787-1
Abstract:
Chaeturichthys stigmatias and Amblychaeturichthys hexanema belong to the family Gobiidae, which are offshore warm fish species and widely distribute in the western Pacific Ocean. In this study, the mitochondrial cytochrome c oxidase subunit I (COI) s...
Effects of rising temperature on growth and energy budget of juvenile Eogammarus possjeticus (Amphipoda: Anisogammaridae)
Suyan Xue, Yuze Mao, Jiaqi Li, Jianguang Fang, Fazhen Zhao
2021, 40(9): 82-89. doi: 10.1007/s13131-021-1863-6
Abstract:
Growth and energy budget of marine amphipod juvenile Eogammarus possjeticus at different temperatures (20°C, 24°C, 26°C, 28°C, 30°C, 32°C and 34°C) were investigated in this study. The results showed that the cumulative mortality rate increased signi...
