Abstract:

This data publication is a database of published estimates of nitrogen, phosphorus, and carbon content of decomposing coarse detritus though time in freshwater ecosystems worldwide. Nutrient content measurements are paired with estimates of detrital mass loss within decomposition time series (i.e., defined cohorts of decomposing material through time) with the goal of understanding patterns and drivers of temporal elemental dynamics of freshwater detritus. A systematic literature search for aquatic decomposition experiments conducted on 29 April 2020 generated 580 records (after trimming for duplicates and obvious relevance). From this literature pool, we extracted 810 decomposition times series and associated environmental data (e.g., temperature, water quality, detrital characteristics). Time series included in this synthesis include a range of detritus types (including terrestrial and aquatic plant material, carcasses, dung, and veneers), ecosystems (including streams, lakes, rivers, and wetlands), and settings (including natural ecosystems, field mesocosms, and laboratory microcosms).

The month during which the cohort was deployed (on Day 0) as reported by the authors. NA indicates no month was reported.

The day of the month the cohort was deployed (Day 0) as reported by the authors. NA indicates no day was reported.

Water temperature during time series. If only measured once or if a mean temperature was reported, this value is used for each time step within the time series.

Water pH during time series. If only measured once or if a mean pH was reported, this value is used for each time step within the time series.

Specific conductance of water during time series. If only measured once or if a mean was reported, this value is used for each time step within the time series.

Dissolved organic carbon (DOC) concentration of water during time series. If only measured once or if a mean was reported, this value is used for each time step within the time series.

If only measured once or if a mean was reported, this value is used for each time step within the time series. Concentrations approaching or below minimum detection limit are reported as by the publication’s authors.

Total phosphorus concentration of water during time series. If only measured once or if a mean was reported, this value is used for each time step within the time series. Concentrations approaching or below minimum detection limit are reported as by the publication’s authors.

Dissolved inorganic nitrogen concentration in water (sum of nitrogen as ammonium, nitrate and nitrite) during time series. If only measured once or if a mean was reported, this value is used for each time step within the time series. Concentrations approaching or below minimum detection limit are reported as by the publication’s authors.

Total nitrogen concentration in water during time series. If only measured once or if a mean was reported, this value is used for each time step within the time series. Concentrations approaching or below minimum detection limit are reported as by the publication’s authors.

Remaining detritus mass as percent of initial mass at a given time step.

Mass of detritus initially deployed, or mass of the detritus cohort on first time step of time series.

Ratio of ash-free dry mass to dry mass of detritus if reported or calculable.

Rate of decomposition of detritus during time series as reported by the authors or if not reported, as calculated from Mass_per_remaining according to Olson first order decay model.

Describes whether percent mass remaining (mass_per_remaining), initial mass (initial_mass_g), and k were derived from dry mass (dm descriptor) or ash-free dry mass (afdm descriptor). The “_postleach” suffix indicates that the mass provided was from sample of leached detritus and thus the 100% mass is not the same as a true 100% dry mass (see Meas_Day for number of days detritus was leached). The descriptor “organic_carbon” denotes that mass loss was estimated by changes in carbon content . dm = dry mass afdm = ash-free dry mass.

The number of replicate detritus units sampled per time point within the decomposition time series. For example, the number of leaf packs pulled from a stream at a given time point.

This field indicates if the percent land use/land cover of the study site is reported in the publication that was not extracted as part of this dataset. The response applies to the entire time series, not a specific time step.

This field indicates if information describing some aspect of the invertebrate community (e.g., composition, biomass, abundance) is reported in the publication. The response applies to the entire time series, not a specific time step.

This field indicates if information describing some aspect of the microbial community other than ergosterol (e.g., composition, production, biomass) was reported in the publication. The response applies to the entire time series, not a specific time step.

Description:

Data included in this synthesis were drawn from primary literature. A systematic literature search for aquatic decomposition experiments was conducted on 29 April 2020 using the databases Academic Search Complete, Agricola, and Web of Science and the keywords "(litter OR leaf OR leaves OR detrit* OR wood OR cellulose OR "coarse particulate") AND (freshwater OR wetland* OR stream* OR river* OR lake*) AND (C:N OR C:P OR N:P OR C:nutrient OR "nutrient content" OR "nitrogen content" OR "N content" OR "phosphor* content" OR "P content" OR "nutrient content" OR minerali* or immobili* or "nutrient release") AND (decompos* OR decay)". The initial search resulted in 3075 records, which were trimmed for duplicates and obvious relevance to 580 records. Each publication was screened for inclusion according to the following criteria: (i) studies described decomposing coarse particulate organic matter (CPOM) in a freshwater ecosystem, (ii) at least two time points of at least one measure of carbon, nitrogen, and/or phosphorus content such as stoichiometric ratios (e.g., C:N, C:P, or N:P), percent, or mass were reported, (iii) some measure of mass loss (e.g., mass, percent mass remaining, or a decomposition rate) were reported, and (iv), detritus was fully submerged during the entire decomposition process but not buried in peat or sediments. We included studies conducted in laboratory and field settings, including field mesocosms, and those that manipulated environmental conditions, such as nutrient availability or temperature, within relatively natural ranges. We did not consider studies that used nutrient diffusing substrates, introduced novel contaminants (e.g., pesticides, pharmaceuticals, nanoparticles), or that used autoclaved detritus. Data from studies conducted in brackish water or that manipulated salinity above normal freshwater limits were also excluded. Data from included publications were extracted as time series into .txt files. Time series describe the decomposition of litter cohorts – a single detritus type within a given environment or treatment, whose characteristics are followed through time. More than one time series was often extracted from a single study or publication; for example, a study that compared the decomposition of maple leaves and beach leaves in a single stream would result in two time series while a study that compared the decomposition of maple leaves among 5 streams would result in 5 time series. Each time series includes the core nutrient and mass loss data over time, environmental data, and metadata describing the study and the publication. Data were extracted using the extractor programs WebPlotDigitizer or DataThief. Extracted data were reviewed independently by three members of the authorship team (the data extractor and two reviewers). All three assessed whether the data met the criteria for inclusion in this dataset and the quality of the data as published. Each data file was spot-checked against the publication by the two reviewers. Disagreements and concerns were discussed among the three and unanimous consent was required to include the study in the data set. The .txt data files were finally aggregated into a single .csv file using R code in "DetNut_Tidy_Database.Rmd", where column names were cleaned and factor variable names were collapsed into unified categories.
