Summary
Rice fields harbor significant microcrustacean diversity, with studies increasingly focusing on active forms. These artificial environments hold substantial potential for storing diverse microcrustacean species.
Area of Science:
- Ecology
- Biodiversity Studies
- Aquatic Entomology
Background:
- Rice fields, often perceived as artificial ecosystems, are increasingly recognized for their ecological significance.
- Microcrustaceans play crucial roles in aquatic food webs and ecosystem functioning.
- Understanding the diversity and distribution of microcrustaceans in rice fields is essential for biodiversity conservation.
Purpose of the Study:
- To analyze global research trends on microcrustaceans in rice fields.
- To assess the potential of rice fields as reservoirs of microcrustacean diversity.
- To evaluate the focus on active versus dormant microcrustacean forms in scientific literature.
Main Methods:
- A scientometric analysis was conducted using data from Web of Science and Scopus databases.
- 77 studies published before 2019 were compiled and analyzed.
- Publication trends, geographical distribution, taxonomic focus, and species richness were quantified.
Main Results:
- Research on microcrustaceans in rice fields has shown a positive trend over 35 years.
- Studies originated from 18 countries, with a concentration in Japan, Italy, the United States, and Spain.
- Cladocera and Ostracoda were the most studied microcrustacean groups, with high species richness found in Italy, Thailand, Malaysia, Spain, France, Japan, and Brazil.
- The majority of studies (87%) focused on active microcrustacean forms, with limited attention to dormant stages.
- Only 15.5% of rice-growing countries have documented their microcrustacean richness, indicating vast unexplored potential.
Conclusions:
- Rice fields represent valuable, yet under-explored, habitats for microcrustacean biodiversity.
- Future research should investigate dormant microcrustacean forms and expand geographical coverage.
- Conservation efforts should consider the ecological importance of microcrustaceans in agricultural landscapes.
