Question

What represents eutrophication diversity or dominance index?

Answer 1

Relationship between eutrophication and species diversity and abundance. Correlations between (A) foraminiferal diversity H(S) in Gulf of Mexico core BC-10 and fertilizer use in USA, (B) ostracod diversity H(S) in Gulf of Mexico core BC-10 and fertilizer use in USA, (C) foraminiferal diversity E(S100) in Osaka Bay core OS3 and discharges of COD (chemical oxygen demand) from Osaka Prefecture, and (D) ostracod abundance (number of specimens per 10 g dry sediment) in Osaka Bay core OS3 and discharges of COD from Osaka Prefecture. Gulf of Mexico data from Alvarez Zarikian et al. (2000); Osaka Bay data from Yasuhara et al. (2007) and Tsujimoto et al. (2008).
