Data from: Road salt pollution shifts urban stormwater ponds toward cyanobacterial dominance

Code and data for characterizing phytoplankton and periphyton communities in ponds based on diagnostic pigments and evaluating the effects of water quality factors on different taxonomic groups.Pond_pigments_2022_ms.csv contains sample pigment data with rows corresponding to unique entries and columns corresponding to Site (sampling location name), Type (phytoplankton "Top" and periphyton "Slides"), and various pigments (Fucoxanthin, Neoxanthin, Violaxanthin, Diadinoxanthin, Myxoxanthophyll, Alloxanthin, Diatoxanthin, Lutein, Zeaxanthin, Lutein.Zeaxanthin, Canthaxanthin, Chlorophyll.b, Chlorophyll.a, and Pheophytin.a; with units in µg/L for "Top" samples and µg/cm2/d for "Slides" samples).Pond_sites_2022_ms.csv contains site data with rows corresponding to sampling locations with columns corresponding to Site (sampling location name), Latitude (sampling location latitude), Longitude (sampling location longitude), Total Phosphorus (as P) (total phosphorus concentration; mg/L), NO3+NO2 (as N) (nitrate + nitrate concentration; mg/L), Total Suspended Solids (total suspended solids concentrations; mg/L), Field pH (field-measured pH; pH units), Field Temp (field-measured surface temperature; °C), Chloride (dissolved chloride concentration; mg/L), Total Copper (total copper concentration; µg/L), Total Sodium (total sodium concentration; µg/L), and Conductance (specific conductance µS/cm).Code presented in Pond_pigments_R_code_ms.R

本数据集提供基于诊断色素（diagnostic pigments）表征池塘浮游植物（phytoplankton）与周丛生物（periphyton）群落的代码与数据，同时可用于评估水质因子对不同分类类群的影响。Pond_pigments_2022_ms.csv 包含样本色素数据，其中行对应唯一采样条目，列依次为：Site（采样位置名称）、Type（浮游植物"Top"样本与周丛生物"Slides"样本），以及多种色素：岩藻黄素（Fucoxanthin）、新黄素（Neoxanthin）、紫黄质（Violaxanthin）、双甲藻黄素（Diadinoxanthin）、黏藻黄素（Myxoxanthophyll）、别黄素（Alloxanthin）、硅藻黄素（Diatoxanthin）、叶黄素（Lutein）、玉米黄质（Zeaxanthin）、叶黄素-玉米黄质（Lutein.Zeaxanthin）、角黄素（Canthaxanthin）、叶绿素b（Chlorophyll.b）、叶绿素a（Chlorophyll.a）与脱镁叶绿素a（Pheophytin.a）；其中"Top"样本的单位为µg/L，"Slides"样本的单位为µg/cm²/d。Pond_sites_2022_ms.csv 包含采样位点数据，其中行对应各采样位置，列依次为：Site（采样位置名称）、Latitude（采样纬度）、Longitude（采样经度）、Total Phosphorus (as P)（总磷浓度，以P计；单位mg/L）、NO3+NO2 (as N)（硝态氮与亚硝态氮浓度，以N计；单位mg/L）、Total Suspended Solids（总悬浮固体浓度；单位mg/L）、Field pH（野外实测pH值；单位pH）、Field Temp（野外实测表层水温；单位°C）、Chloride（溶解态氯离子浓度；单位mg/L）、Total Copper（总铜浓度；单位µg/L）、Total Sodium（总钠浓度；单位µg/L）以及Conductance（比电导率；单位µS/cm）。相关代码存储于Pond_pigments_R_code_ms.R 文件中。
