title: Data from: Resource limitation and competition shape reproductive allocation and synchrony

description: This dataset accompanies the publication “Resource limitation and
 competition shape reproductive allocation and synchrony” (Oikos, 2025). It
 contains four linked data tables compiled in a single Excel file, which
 together describe the structure, design, and outcomes of a five-year
 mesocosm experiment on reproductive allocation and flowering synchrony in
 clonal wetland plants. Data_Ramets – Records the number of ramets per
 individual, including species identity, pot, and year, providing the base
 for calculating reproductive allocation (RA). DATA_RametsSum – Summarizes
 total numbers of ramets per pot across all years, enabling community- and
 treatment-level analyses. DATA_Treatments – Describes the experimental
 design, specifying hydrological (water-level) treatments and
 dominant-species removal. DATA_Flowering – Reports the number of flowering
 ramets per individual and seed mass measured in 2015. Data values are
 numeric and categorical, standardized for analysis in R (as used in the
 publication). Together, they support replication of analyses on
 reproductive allocation, inter- and intraspecific synchrony, and treatment
 effects under contrasting water regimes and competitive contexts. The
 dataset can be reused for comparative studies of clonal plant
 reproduction, experimental design replication, or meta-analyses on
 reproductive strategies under environmental stress. All data derive from
 controlled experiments with plant material.

 Description of the data and file structure The dataset originates from a
 five-year mesocosm experiment conducted in an experimental garden in the
 Czech Republic (2011–2015). The experiment tested how drought stress and
 the removal of a dominant species influence reproductive allocation and
 flowering synchrony in clonal wetland plants. Four species commonly
 co-occurring in temperate wetlands were grown in controlled containers
 under three hydrological regimes and two competition treatments. Annual
 measurements included the number of total and flowering ramets per
 individual and species, allowing assessment of inter- and intraspecific
 patterns of reproductive investment over time. ### Files and variables
 #### File: DATA_ResourceLimitation.xlsx **Description:** This Excel file
 contains four worksheets summarizing data from a five-year mesocosm
 experiment testing the effects of drought stress and dominant-species
 removal on reproductive allocation and flowering synchrony in clonal
 wetland plants. Each sheet contains numeric and categorical variables
 standardized for analysis in R. **Sheet 1: Data_Ramets** Description:
 Number of total ramets (shoots) per individual plant recorded annually,
 used to calculate reproductive allocation (RA). Variables: * ID
 (sequential identifier); * PlantType (Type of individual origin: P –
 originally planted individual, N – new individual originating from seed
 (generative reproduction), S – clonal individual of Calamagrostis
 canescens (vegetative origin).); * Pot (unique pot ID); * Species (species
 identifier: Ela = Carex elata, Celo = Carex elongata,Cal = Calamagrostis
 canescens, Des = Deschampsia cespitosa); * Year (unique identifier for
 each year 2012, 2013, 2014,2015) * Nramet (number of ramets, including
 both flowering and non-flowering per individuum); * Position (Unique
 identifier of each original plant within the pot) **Sheet 2:
 DATA_RametsSum** Description: Summarized total number of ramets per pot
 across years, used for community-level analyses. Variables: * ID
 (sequential identifier); * Species (species identifier: Ela = Carex elata,
 Celo = Carex elongata, Cal = Calamagrostis canescens, Des = Deschampsia
 cespitosa); * Pot (unique pot ID); * Year (unique identifier for each year
 2012, 2013, 2014,2015) * NrametSum (total number of ramets, including both
 flowering and non-flowering, in a given pot) **Sheet 3: DATA_Treatments**
 Description: Metadata describing the experimental design and treatments
 applied to each pot. Variables: * ID (sequential identifier); * Pot
 (unique pot ID); * WaterLevel (three treatments: l = low, M =
 intermediate, H = high water level); * DominantRemoval (two treatments: R
 = Carex elata removal, N = no removal); * Block (factorial block ID)
 **Sheet 4: DATA_Flowering** Description: Number of flowering ramets per
 individual and seed mass recorded in 2015, used to evaluate reproductive
 investment. Variables: * Pot (unique identifier for each pot); * PlantType
 (N = newly recruited plants during the experiment); * Species (species
 identifier: Ela = Carex elata, Celo = Carex elongata, Cal = Calamagrostis
 canescens, Des = Deschampsia cespitosa); * Seeds_g (weight of achenes
 produced in 2015, in grams); * NrametFruit (number of flowering ramets); *
 Year (unique identifier for each year 2012, 2013, 2014,2015); * WaterLevel
 (three treatment levels: l = low, M = intermediate, H = high water level);
 * DominantRemoval (two treatments: R = Carex elata removal, N = no
 removal); * Block (factorial block ID); * Position (Unique identifier of
 each original plant within the pot) ## Code/software The submission
 includes an R script (`Rcode.txt`) that reproduces the analyses and
 figures described in the associated publication. The script loads the
 experimental data from the four Excel sheets, calculates reproductive
 allocation (RA) and synchrony indices, fits Bayesian mixed models (using
 `rstanarm` and `bayestestR`), and generates summary plots with `ggplot2`.
 All code is written for R (v. 4.3 or later) and uses only open-source
 packages available from CRAN.
