Primary producer biomass and nutrient stocks in phosphorus-limited shallow freshwater ecosystems: literature review data from 1921 - 2024 and Everglades FL, USA case study, June 2021 - June 2023

This data package includes data compiled from a literature review search and Everglades, Florida (FL), USA case study in order to quantify the relationship between (1) planktonic production and water-column total phosphorus (TP), (2) benthic algal production and water-column TP, (3) benthic algal production and benthic microbial TP standing stock, and (4) macrophyte production and macrophyte TP standing stock across P-limited shallow freshwater ecosystems. Our goal was to determine if benthic macrophyte and microbial TP standing stock may better describe variation in macrophyte and microbial production in shallow freshwater ecosystems rather than water-column TP. The search took place using the Clarivate™ (Web of Science™) and Google Scholar™ search engines, and multiple searches occurred using a combination of keywords, which resulted in 425 publications containing usable data. This data package encompasses water depth, water TP, phytoplankton chlorophyll-a, benthic algal chlorophyll-a, benthic algal ash-free dry mass, macrophyte dry mass, benthic microbial TP and total nitrogen (TN) standing stock, and macrophyte TP and TN standing stock found during the literature review and from two Everglades observational studies, including the case study. Publication citation, year, author(s), title, publishers, and digital object identifier are provided to sufficiently trace each data value back to its original study. Data were separated into 23 shallow freshwater ecosystem types, four categories, and two groups. The data package includes four datasets, one of which only contains the Everglades case study data. Data collection for all datasets is complete. FCE1294_Lit_Review_Macro includes macrophyte dry mass, macrophyte TP standing stock, and macrophyte TN standing stock data collected from 220 publications discovered during a literature review to quantify the relationship between planktonic or benthic producer (algae, cyanobacteria, and macrophyte) production and TP concentrations in water or producer biomass across P-limited shallow freshwater ecosystems. One dataset collected within the Greater Everglades, FL, USA is also included. Data publication spanned 1924 to 2026, and data collection spanned summer 1921 to May 2024. FCE1294_Lit_Review_Benthic_Micro includes water depth, water column TP concentration, benthic algal chlorophyll-a, benthic microbial ash-free dry mass, benthic microbial TP standing stock, and benthic microbial TN standing stock data collected from 147 publications discovered during a literature review to quantify the relationship between planktonic or benthic producer (algae, cyanobacteria, and macrophyte) production and TP concentrations in water or producer biomass across P-limited shallow freshwater ecosystems. Two datasets collected within the Greater Everglades, FL, USA are also included. Data publication spanned 1966 to 2026, and data collection spanned June 1975 to October 2023. FCE1294_Lit_Review_Phyto includes water column TP concentration and phytoplankton chlorophyll-a data collected from 58 publications discovered during a literature review to quantify the relationship between planktonic or benthic producer (algae, cyanobacteria, and macrophyte) production and TP concentrations in water or producer biomass across P-limited shallow freshwater ecosystems. Data publication spanned 1985 to 2025, and data collection spanned August 1988 to October 2023. FCE1274_Ever_Case_Study includes water depth, benthic microbial dry mass, ash-free-dry mass, chlorophyll-a, TP and TN concentration and standing stock, total macrophyte dry mass and TP and TN concentration and standing stock, Cladium jamaicense dry mass and TP and TN concentration and standing stock, Eleocharis cellulosa dry mass and TP and TN concentration and standing stock, and total producer biomass and TP and TN concentration and standing stock found within each plot replicate sampled in ridge and slough habitats found at three Shark River Slough and three Taylor Slough/Panhandle wetland sites in Everglades National Park, FL, USA. Data collection spanned 2021-06-14 to 2023-06-27, and each plot was sampled once.

本数据集汇编自文献检索以及美国佛罗里达州大沼泽地（Everglades, FL）案例研究，旨在量化磷限制浅水淡水生态系统中四类关联关系：(1) 浮游生物生产力与水柱总磷（water-column total phosphorus, TP）；(2) 底栖藻类生产力与水柱总磷；(3) 底栖藻类生产力与底栖微生物总磷现存量；(4) 大型植物（macrophyte）生产力与大型植物总磷现存量。本研究旨在探究，相较于水柱总磷，底栖大型植物与微生物总磷现存量是否能更好地解释浅水淡水生态系统中大型植物及微生物生产力的变异。本次文献检索使用了科睿唯安（Clarivate™）Web of Science™及谷歌学术（Google Scholar™）搜索引擎，通过多组关键词组合开展多次检索，最终获得425篇包含可用数据的文献。本数据集涵盖了文献检索及两项大沼泽地观测研究（含本次案例研究）中获取的如下数据：水深、水柱总磷、浮游植物叶绿素-a、底栖藻类叶绿素-a、底栖藻类无灰干重、大型植物干重、底栖微生物总磷及总氮（Total Nitrogen, TN）现存量，以及大型植物总磷及总氮现存量。所有数据均附带文献引用、发表年份、作者、标题、出版方及数字对象标识符（Digital Object Identifier, DOI），可完整追溯每条数据的原始研究来源。数据被划分为23种浅水淡水生态系统类型、4个类别及2个组别。本数据集包含4个子数据集，其中一个仅包含大沼泽地案例研究数据。所有子数据集的采集工作均已完成。FCE1294_Lit_Review_Macro：该子数据集包含从220篇文献检索结果中采集的大型植物干重、大型植物总磷现存量及大型植物总氮现存量数据，用于量化磷限制浅水淡水生态系统中，浮游或底栖生产者（藻类、蓝细菌（cyanobacteria）及大型植物）的生产力与水体总磷浓度或生产者生物量之间的关联。本数据集同时包含美国佛罗里达州大沼泽地地区采集的数据。数据发表时间跨度为1924年至2026年，数据采集时间跨度为1921年夏季至2024年5月。FCE1294_Lit_Review_Benthic_Micro：该子数据集包含从147篇文献检索结果中采集的水深、水柱总磷浓度、底栖藻类叶绿素-a、底栖微生物无灰干重、底栖微生物总磷现存量及底栖微生物总氮现存量数据，用于量化磷限制浅水淡水生态系统中，浮游或底栖生产者（藻类、蓝细菌及大型植物）的生产力与水体总磷浓度或生产者生物量之间的关联。本数据集同时包含两项美国佛罗里达州大沼泽地地区采集的数据。数据发表时间跨度为1966年至2026年，数据采集时间跨度为1975年6月至2023年10月。FCE1294_Lit_Review_Phyto：该子数据集包含从58篇文献检索结果中采集的水柱总磷浓度及浮游植物叶绿素-a数据，用于量化磷限制浅水淡水生态系统中，浮游或底栖生产者（藻类、蓝细菌及大型植物）的生产力与水体总磷浓度或生产者生物量之间的关联。数据发表时间跨度为1985年至2025年，数据采集时间跨度为1988年8月至2023年10月。FCE1274_Ever_Case_Study：该子数据集包含美国佛罗里达州大沼泽地国家公园内三个鲨鱼河沼泽（Shark River Slough）及三个泰勒河沼泽/狭长湿地（Taylor Slough/Panhandle wetland）样点的脊-沟生境中，每个重复样地采集的如下数据：水深、底栖微生物干重、无灰干重、叶绿素-a、总磷及总氮浓度与现存量、大型植物总干重及总磷、总氮浓度与现存量、牙薹（Cladium jamaicense）干重及总磷、总氮浓度与现存量、细叶荸荠（Eleocharis cellulosa）干重及总磷、总氮浓度与现存量，以及总生产者生物量及总磷、总氮浓度与现存量。数据采集时间为2021年6月14日至2023年6月27日，每个样地仅采样一次。本项目及数据集配套的R代码及其Zenodo数字对象标识符已上传至GitHub仓库Kleindl_et_al_2026_Production_and_Enrichment_Shallow_Freshwater_Systems，链接为https://github.com/GaiserLab/Kleindl_et_al_2026_Production_and_Enrichment_Shallow_Freshwater_Systems.git
