TREND ANALYSIS OF RESEARCH ON PHYTOPLANKTON TRAITS AS ECOLOGICAL INDICATORS

This study employs bibliometric analysis to identify trends and research hotspots in the use of phytoplankton traits as ecological indicators.We analyzed 3352 articles published in the Web of Science Core Collection database from 2000 to 2023, focusing on phytoplankton traits, their role as indicators, and their application in aquatic ecosystem monitoring.This study reveals a significant increase in publications on this topic, particularly since 2010.The United States, China, and Germany emerged as leading contributors in this field.Our analysis identifies four major research clusters: (1) using phytoplankton traits to indicate environmental changes in rivers, lakes, and oceans, (2) using phytoplankton traits as bioindicators for specific environmental factors like nutrients and pollutants, (3) exploring the molecular mechanisms of phytoplankton trait variations and new species discoveries, and (4) investigating the relationship between phytoplankton traits and the food web dynamics.Research on phytoplankton traits is rapidly advancing, with significant potential to enhance understanding and monitoring of aquatic ecosystems.Future research directions include further investigating the molecular mechanisms of trait changes, developing more robust bioindicators for specific pollutants, and exploring the ecological implications of trait variations in food webs.
