These files are related to the publication "Legacies of invasive plant management: effects of leaching from glyphosate-treated and untreated plants on germination and early growth of native macrophytes" in the journal Biological Invasions (DOI: 10.1007/s10530-022-02794-7). There are a total of 8 files which are described below: DATA FILES AmmanniaData2020Fall.csv Contains the following columns: Replicate = replicate (Petri dish) Day = assessment day Total_seeds = number of total seeds Germinated = number of germinated seeds Sprouted = number of sprouted seeds PGerminated = proportion of germinated seeds Psprouted = proportion of sprouted seeds Plant = plant from which the leachate was made; none means just tap water Treatment = C (tap water control); WT (water-sprayed Typha); ST (5%-glyphosate-sprayed Typha); WP (water-sprayed Phragmites); SP (5%-glyphosate-sprayed Phragmites) Concentration = applied glyphosate concentration (0: tap water; 5: 5%; 8: 8%) Experiment = either field or garden material VariabilityAssessment.csv Contains the following columns: Seedling = number of the seedling Emily = seedling length measurements (cm) made by Emily Varun = seedling length measurements (cm) made by Varun Verena = seedling length measurements (cm) made by Verena TyphaData2020Fall-Germination.csv Contains the following columns: Treatment = C (tap water control); WT (water-sprayed Typha); ST (5%-glyphosate-sprayed Typha); WP (water-sprayed Phragmites); SP (5%-glyphosate-sprayed Phragmites) Replicate = replicate (Petri dish) Day = assessment day Total_seeds = number of total seeds Germinated = number of germinated seeds PGerminated = proportion of germinated seeds Plant = plant from which the leachate was made; none means just tap water Concentration = applied glyphosate concentration (0: tap water; 5: 5%; 8: 8%) Experiment = either field or garden material TyphaData2020Fall-Length.csv Contains the following columns: Treatment = C (tap water control); WT (water-sprayed Typha); ST (5%-glyphosate-sprayed Typha); WP (water-sprayed Phragmites); SP (5%-glyphosate-sprayed Phragmites) Replicate = replicate (Petri dish) Day = assessment day Seed number = number of the seed within a replicate Shoot length = length of the seedling shoot part (cm) Root length = length of the seedling root part (cm) Total_length_cm = length of the seedling (cm) Plant = plant from which the leachate was made; none means just tap water Concentration = applied glyphosate concentration (0: tap water; 5: 5%; 8: 8%) Experiment = either field or garden material TyphaData2020Fall-ChangesAverageLength.csv Contains the following columns: Days = day intervals Change_ave_length = rate of change in average seedling length Treatment = C (tap water control); WT (water-sprayed Typha); ST (5%-glyphosate-sprayed Typha); WP (water-sprayed Phragmites); SP (5%-glyphosate-sprayed Phragmites) Plant = plant from which the leachate was made; none means just tap water Concentration = applied glyphosate concentration (0: tap water; 5: 5%; 8: 8%) Experiment = either field or garden material Leachate_data.csv Contains the following columns: Treatment = glyphosate treatment (5: 5%; 8: 8%) Replicate = replicate unit Sampling_Time = sampling time after submerging of plant litter (days) Time = sampling time after submerging of plant litter (different format) ppb = concentration of the substance in water Substance = Glyphosate or AMPA ugSubs_gLitter = Total amount of substance leached out of plant litter (µg/g) CODE FILES Leaching_Code.R R code for the leaching experiments Germination_Code_Biol-Invasions-Journal.R R code for the germination experiments
