Special Session 3: Ecological and Evolutionary Paradigms in Marine Biology and How Meiofauna can be Used to Address Them: no. SS3-9Conference Theme: Life in the Changing OceanSmall benthic organisms, meiofauna, have been investigated less intensively compared to larger macrofauna, resulting in greater taxonomic uncertainty and less census data accumulation. However, they are the most abundant and diverse group of (non-microbial) organisms in marine sediments. Hundreds of specimens and dozens of species can be obtained from small amount of sediment. Two taxa of meiofauna, the crustacean Ostracoda and protozoan Foraminifera are known as microfossils. Their microscopic-size …published_or_final_versio
