Bibliometric insights and content analysis of diatom paleolimnology in lakes: Global perspectives and Indonesian contributions over the last decade

This study evaluates global scientific publications on diatom-based lake paleolimnology from 2014 to 2024, with a focus on Indonesia's contributions, using bibliometric and content analysis of Scopus data. A total of 378 publications were identified, with relatively stable annual output. The Journal of Paleolimnology is the leading publication outlet, and Agricultural and Biological Sciences is the most studied subject area. Canada, the United States, and China dominate in publication volume, with Canadian authors being the most influential. Indonesia's research remains limited to a few lakes (Towuti, Rawapening, and Warna), indicating challenges but also potential for expansion. Keyword analysis revealed seven clusters centered on paleolimnology and diatoms. Underexplored research areas include microenvironment, miocene, modern analogs, modern sediments, nutrient limitation, siliceous components, and Patagonian palaeoenvironments. These themes suggest promising directions such as investigating Miocene microhabitats, improving ecological reconstructions through modern analog comparisons, and studying nutrient dynamics and silica availability, which are crucial for diatom growth and lake productivity. The study's findings aim to inform and enhance paleolimnology research in Indonesia and foster greater international collaboration.
