Bryde’s whales produce Biotwang calls, which occur seasonally in long-term acoustic recordings from the central and western North Pacific Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-18 Ann N. Allen, Matt Harvey, Lauren Harrell, Megan Wood, Angela R. Szesciorka, Jennifer L. K. McCullough, Erin M. Oleson
In 2014, a novel call was discovered in autonomous acoustic recordings from the Mariana Archipelago and designated a “Biotwang”. It was assumed to be produced by a baleen whale, but without visual verification it was impossible to assign a species. Using a combination of visual and acoustic survey data collected in the Mariana Archipelago, we determined that Biotwangs are produced by Bryde’s whales

Shading responses are species-specific in thermally stressed corals Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-13 Sophia L. Ellis, Peter Butcherine, Alejandro Tagliafico, Conor Hendrickson, Brendan P. Kelaher, Kai G. Schulz, Daniel P. Harrison
Light is critical to coral growth through endosymbiont photosynthesis but can also act with elevated temperatures to cause coral bleaching. When more light is absorbed than can be used for photosynthesis, elevated irradiance can damage symbiont photosynthetic machinery. Hence, solar-radiation management through shading has been suggested to alleviate coral bleaching during marine heatwaves. Acropora

To alleviate the pressure of economic development on the marine environment, the Marine Ecological Compensation (MEC) has become a major policy tool for the Chinese government to reconcile the contradiction between economic development and the marine environment. In this paper, we propose a novel two-stage bargaining game data envelopment analysis (DEA) model to evaluate the performance of MEC under

Spatiotemporal evolution of air-sea CO2 flux in the Northwest Pacific and its response to ENSO Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-09 Haiyi Shi, Ying Chen, Hui Gao
Global warming, driven by human activities since the Industrial Revolution, has significantly elevated atmospheric carbon dioxide (CO2) levels, leading to higher global temperatures and a rise in extreme weather events. The ocean, as a major carbon sink, has absorbed about 30% of human-induced carbon emissions, helping mitigate global warming’s impacts. This study examines the spatiotemporal distribution

Factors influencing mangrove carbon storage and its response to environmental stress Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-07 Chuanyi Guo, Pei Sun Loh, Jianxiong Hu, Zengxuan Chen, Siriporn Pradit, Chantha Oeurng, Ty Sok, Che Abd Rahim Mohamed, Choon Weng Lee, Chui Wei Bong, Xixi Lu, Gusti Z. Anshari, Selvaraj Kandasamy, Jianjun Wang
Mangrove forests serve as significant carbon sinks and play a crucial role in mitigating climate change. Currently, the response of mangroves to intensified climate change and human activities, and the factors that influence the magnitude of carbon storage in their sediments remain uncertain. To address these questions, two sediment cores were collected from the mangrove reserve in Pearl Bay, Guangxi

Carbon budgets of coral reef ecosystems in the South China Sea Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-06 Hongqiang Yan, Qi Shi, Lijia Xu, Huiling Zhang, Meixia Zhao, Shichen Tao
The coral reef ecosystem is one of the most productive ecosystems in the ocean, and is also an important calcium carbonate deposition region. Because excess production is very low in coral reefs, organic carbon reservoirs are very limited. During the calcification process, each mole of CaCO3 will produce 1 mol of CO2, approximately 60% of which will be released into the atmosphere through the sea-air

Macrobenthic communities in the polymetallic nodule field, Indian Ocean, based on multicore and box core analysis Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-05 Santosh Gaikwad, Sabyasachi Sautya, Samir Damare, Maria Brenda Luzia Mascarenhas-Pereira, Vijayshree Gawas, Jayesh Patil, Mandar Nanajkar, Sadiq Bukhari
Managing deep-sea mining is challenging due to limited data on species and habitat distribution, hindering decision-making. In less-explored polymetallic nodule sites in the Indian Ocean, management approaches are deemed unfeasible due to a substantial lack of data. In this study, we aim to bridge the knowledge gap through a detailed analysis of the macrobenthos (fauna > 300 µm) obtained with two sampling

Seasonal changes of plankton community and its influencing factors in subtropical coastal marine areas revealed by eDNA-based network analysis Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-05 Xiaoqi Lin, Kunhuan Li, Hancheng Zhao, Yan Gao, Zonghang Zhang, Lin Wang, Xinjie Wang, Edmond Sanganyado, Zhao Zheng, Qilin Gutang, Sailan Liu, Ping Li, Xiuli Yan, Zhaoyun Chen, Jianqing Lin, Wenhua Liu
IntroductionCoastal marine ecosystems are among the most ecologically and socio-economically dynamic regions on Earth, and the study of eukaryotic planktonic communities is an important aspect of aquatic ecology. It is essential to monitor plankton biodiversity and identify influencing factors in order to measure human effects on coastal waters and help contribute to ecosystem preservation. Environmental

Nearshore microbial communities of the Pacific Northwest coasts of Canada and the U.S. Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-05 Linda D. Rhodes, Nicolaus G. Adams, Ramon Gallego Simon, Maria T. Kavanaugh, Simone R. Alin, Richard A. Feely
A survey of marine pelagic coastal microbial communities was conducted over a large geographic latitude range, from Cape Mendocino in northern California USA to Queen Charlotte Sound in British Columbia Canada, during the spring to summer transition. DNA metabarcoding and flow cytometry were used to characterize microbial communities. Physical and chemical oceanography indicated moderate conditions

Recognition of feeding sounds of large-mouth black bass based on low-dimensional acoustic features Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-05 Shijing Liu, Shengnan Liu, Renyu Qi, Haojun Zheng, Jiapeng Zhang, Cheng Qian, Huang Liu
IntroductionThe eating sounds of largemouth black bass (Micropterus salmoides) are primarily categorized into swallowing and chewing sounds, both intensities of which are closely correlated with fish density and feeding desire. Therefore, accurate recognition of these two sounds is of significant importance for studying fish feeding behavior.MethodsIn this study, we propose a method based on low-dimensional

Sustainable solutions: exploring risks and strategies in Pakistan’s seafood trade for marine conservation Front. Marine Sci. (IF 2.8) Pub Date : 2024-09-05 Muhammad Mohsin, Hengbin Yin, Ana Mehak
Global literature highlights risks in the seafood trade and suggests mitigation methods, but these issues are often overlooked in developing countries, particularly in Pakistan, due to ineffective policy implementation. This underlines the urgent need for a thorough investigation into Pakistan’s seafood trade to address its multifaceted risks and revive this agricultural sector. This study is notable
