Resum	The Benthic Index of Biotic Integrity (B-IBI) is an ecological assessment metric that measures the health and integrity of benthic (seafloor) communities based on the composition, abundance, and diversity of benthic fauna. Developed by James Karr in 1981 for freshwater fish assemblages and later adapted for marine benthic communities, the B-IBI provides a holistic measure of ecosystem condition integrating responses to multiple stressors including pollution, habitat degradation, and resource depletion.	Phytoplankton size classification is a fundamental framework for organizing plankton communities and understanding their ecological roles and biogeochemical impacts. Developed by Sieburth, Smetacek, and Lenz in 1978, size classes (pico-, nano-, micro-, macro-phytoplankton) define distinct functional groups with different nutritional requirements, growth rates, grazing vulnerabilities, and sinking rates. Size-based classification enables rapid assessment of plankton community structure and prediction of ecosystem responses to environmental change.
