title: Data from: Anthropogenic nutrient inputs affect productivity-biodiversity relationships in marine tintinnid assemblages

description: Although the productivity-biodiversity relationship (PBR) has been a hot
 topic, few studies have considered how anthropogenic pressures affect PBRs
 in marine microzooplankton. Here, we provide the first insights into PBRs
 in tintinnid assemblages using 18-year data from Jiaozhou Bay, a typical
 coastal bay in the Yellow Sea. We hypothesized and verified that PBRs vary
 across contrasting anthropogenic nutrient inputs and that functional and
 phylogenetic diversity would deliver more information than conventional
 species richness. High productivity promotes more diversity under low to
 medium rather than high anthropogenic nutrient inputs. Compared to species
 richness, functional and phylogenetic diversity reveals more PBR patterns
 and responds more quickly in response to varying anthropogenic inputs. A
 concave+ PBR is revealed for functional diversity in the ecozone with
 highly active water exchange. Our study contributes to the understanding
 of PBR in marine unicellular secondary producers and their responses to
 anthropogenic nutrient inputs in coastal ecosystems.
