Livelihood strategies are an effective response to survival risks and stress shocks. Agricultural residents engaged in agriculture, forestry, animal husbandry, and fishery, who are extremely dependent on natural resources, are vulnerable to various livelihood risks. Therefore, the livelihood strategies of agricultural residents are increasingly receiving attention from researchers around the world. However, research on the livelihood strategies of agricultural residents has not yet been systematically analyzed through bibliometrics. Our study was based on 1424 publications in the Web of Science Core Collection database (WoSCC) from 2014 to 2023 to analyze the development history, research hotspots, and trends in the field. Bibliometric analysis was conducted on publications, countries, institutions, authors, journals, and keywords, as well as cited journals and cited references using Excel and CiteSpace software. The number of publications has steadily increased and showed an upward trend. The United States and China were the countries with the most contributions, and Chinese institutions were more active. Cooperation between authors was relatively weak. Sustainability was one of the most productive and highly cited journals. The research hotspots mainly included the relationship between climate change and the livelihood strategies of agricultural residents, the relationship between the land and the livelihood strategies of agricultural residents, the sustainable development of livelihood strategies of agricultural residents, and the characteristics of livelihood strategies of agricultural residents. This is the first time that bibliometric and visual analyses have been conducted on the livelihood strategies of agricultural residents, which may further promote development of the field and lay a foundation for future research.

The “Ten-Year Fishing Ban” policy in the Yangtze River Basin aims to restore ecological diversity but poses significant challenges for the fishermen in their transition to alternative livelihoods. This study focuses on fishermen who worked on Poyang Lake, using the sustainable livelihood framework and the theory of planned behavior, combined with fuzzy-set qualitative comparative analysis (fsQCA) and descriptive statistics, to explore the interaction effects of livelihood capital, ecological cognition, and compensation policies on fishermen’s behavioral responses. Key findings include the following: natural, financial, and psychological capital are core drivers of enhanced ecological cognition, with combined effects significantly increasing sensitivity to policy and environmental changes through pathways like “ecological transition drive”, “knowledge adaptation support”, and “multi-cooperation synergy”. Attitude, perceived behavioral control, and compensation policy transparency are crucial for positive responses, while social norms and policy fairness can compensate for individual motivation deficits, forming pathways like “ecological drive-policy recognition” and “norm drive-social support”. Current issues such as low compensation standards, insufficient retraining, and gender differences limit policy effectiveness. Optimizing measures like differentiated fishing permits, dynamic compensation mechanisms, and cultural empowerment are needed to balance ecological protection and social equity. The study suggests enhancing financial and psychological capital, improving vocational training systems, and increasing policy transparency to provide theoretical and practical references for sustainable global fisheries management.

Seasons are the important influencing factor for gut microbiota, which in turn affects the ecology and evolution of the host. The seasonal variation in gut microbiota has increasingly attracted the attention of researchers and professionals worldwide. However, studies of seasonal variations in gut microbiota have not been systematically analyzed by bibliometrics or visual analysis. This study is based on 271 publications from 2012 to 2022 in the Web of Science Core Collection database (WOSCC) to analyze hot spots and trends in this field. The collaborations between different countries, institutions, authors, journals, and keywords were bibliometrically analyzed using Excel, CiteSpace (Version 6.2. R4), and VOSviewer (version 1.6.19) software. The number of publications has been increasing rapidly and shows a general upward trend. China and the Chinese Academy of Sciences are the country and institution contributing the most, respectively. The research hotspots and trends mainly include the diversity of gut microbiota communities in different seasons, the relationship between diet and gut microbiota in seasonal changes, and the relationship between gut microbiota and evolutionary adaptation in seasonal changes. This is the first bibliometric and visualization analysis of seasonal variations in gut microbiota, which may advance this field and lay the foundation for future research.

Food resources are the fundamental basis for the survival and reproduction of animals. Diet research is the foundation for understanding their ecological habits and is of great significance for evaluating their survival status and carrying out effective protection and management. South China sika deer (Cervus nippon kopschi) is the most endangered subspecies of wild sika deer in China, with a small population and a shrinking distribution area. Here, we used DNA metabarcoding technology to study the diet composition of C. n. kopschi in Taohongling Sika Deer National Nature Reserve in Jiangxi, China. Comparative analysis of diet composition among different areas (A–E) of C. n. kopschi was conducted, as well as C. n. hortulorum raised in the same areas. We found that the dominant families in the diet composition of C. n. kopschi were Rosaceae (46.73% of relative abundance), Anacardiaceae (6.02%), Poaceae (5.54%), and Fabaceae (3.92%), with Rubus (45.43%) being the absolute dominant genus. Thirty-two preferred plant species were identified in the diet of C. n. kopschi. The highest relative abundance (45%) was Rubus reflexus. The dominant family and genus in the diet composition of C. n. hortulorum were Fabaceae (33.89%) and Pueraria (32.87%), respectively. Of the 15 preferred plant species, the highest relative abundance was Pueraria montana (33%). The richness, diversity, and evenness of diet composition in Area B of C. n. kopschi were the highest among all areas, with significant differences compared to Areas C, D, and E. Diet composition of deer in Area A did not differ significantly from those in other areas. Principal coordinate analysis (PCoA) and nonmetric multidimensional scaling (NMDS) both indicated a significant separation in the diet composition of C. n. kopschi and C. n. hortulorum, while Area B showed significant separation from the other areas. This study elaborates on the diet composition information of C. n. kopschi and can provide a reference for the protection and improvement of the habitat of sika deer.
