[Burial, source characteristics and influencing factors of organic carbon in mangrove sediments at the mouth of the Oujiang River Estuary, China].

Mangrove forests are crucial coastal "blue carbon" ecosystems, known for their significant carbon sequestration capabilities to "carbon neutrality" and mitigating global climate change. We used Pb radioisotope dating to analyze sedimentation rates in the sediments of the Oujiang River Estuary mangrove forest, to calculate organic carbon burial rate, and to assess the characteristics and sources of organic carbon burial. The results showed that the average total organic carbon content in the sediments was 1.

[Niche and interspecific association of the dominant fish in the south coastal waters of Wenzhou, China].

The studies about the niche and interspecific association in China were mainly focused on the plants, birds and marine animals, and seldom on fish. Based on the fishery resources survey in spring (May) and autumn (September) in 2015, the associations among major fish species in south coastal waters of Wenzhou were investigated. The methods including niche breadth, niche overlap, variance ratio (VR), Χ-test, association coefficient (AC), percentage of co-occurrence (PC) and point correlation coefficients (Ф) were used.

[Application of species distribution models in the prediction of marine potential habitat: A review].

The relationship between the distribution of halobios and environmental variables has been a focus of present research in marine ecology. Species distribution models (SDMs) have been widely employed to predict the distribution patterns and potential habitat suitability assessments of marine species and provide an efficient approach for marine biodiversity conservation, invasive species prevention, and fishery management. SDMs mainly include habitat suitability index models, mechanism models, and statistical models.

[Niche and interspecific association of nekton in the south coastal waters of Cangnan, Zhe-jiang, China].

In this paper, the interaction between the species Population were analyzed based on the data of major nekton species in the south coastal waters of Cangnan in spring and autumn 2014. A series of methods including niche breadth, niche overlap, χ2 - test and association coefficient (AC) based on a 2x2 contingency table were used. The results showed that the major nekton species in the south coastal waters of Cangnan were classified into three groups, i.
