Dataset: Direct and indirect effects of climate change in coastal wetlands

This dataset was created based off the Coastwide Reference and Monitoring Sites (CRMS) data (Retrieved from Coastal Information Management System database: http://cims.coastal.louisiana.gov [Accessed 21 June 2017] ). We analysed plant species composition, soil pore water salinity (ppt) and water depth (cm) part of that CRMS dataset that were consistently monitored by CRMS over the period of 11 years (2007 – 2017, see file "VegAllEnvData_03july2018.csv") Additionally, to assign each species in the dataset as native/introduced, we obtained a Louisiana introduced species lists from the Louisiana Native Plant Society (https://www.lnps.org/references, see file "LA_Plants_Clean.csv"). The outcomes of the analysis of these date were published in: Christina Birnbaum, Paweł Waryszak and Emily C. Farrer (accepted in 2021) Effects of climate and invasion on vegetation patterns in rapidly declining coastal wetlands in Louisiana. Wetlands

Dataset: seedlings emergence and survival following topsoil transfer, Western Australia

These data refer to the paper by Waryszak et al (2020). These data record the four vegetation surveys (spring 2012, spring 2013, autumn 2013 and autumn 2014) following topsoil transfer as part of the restoration PhD project on restoration of Banksia Woodland of Swan Coastal Plain, undertaken at Murdoch University in collaboration with the Department of Parks and Wildlife in Western Australia. The top 5-10 cm of soil, where most of the propagules are stored, was stripped and transferred to six restoration study sites in mid–April 2012 (16 ha in total). A fully factorial experimental plot design was used to investigate the effects of environmental filter manipulation treatments on emergence and survival of native plants (density, diversity, functional types) emerging from the transferred topsoil.

Dataset: Planted mangroves cap toxic petroleum-contaminated sediments

Dataset contains information on hydrocarbon content in mangrove sediments from three sampling sites at Stony Creek, Victoria, Australia. At each sampling site, we collected three soil cores (1 m deep or until bedrock was reached) using a PVC pipe (5 cm internal diameter, 120 cm length) to profile the hydrocarbon content within the sediment. Nine sediment cores (collected on 03/July/2019) were immediately transported to Deakin University (Burwood campus) and sliced at six depth intervals: 0–10, 10–20, 20–30, 30–50, 50–75 and 75–100 cm. Wet sediment samples were stored at 4℃ and shipped to the Analytical Reference Laboratory (Welshpool, Western Australia) for total petroleum hydrocarbon (TPH) and polyaromatic hydrocarbons (PAH) analyses. The dry content of PAHs and TPH and soil organic matter in mangrove sediments was estimated from a set of nine additional cores collected at the same three mangrove sites within the 5m by 5m plots. These additional soil cores were sliced at compatible intervals and dried at 60℃ (until a consistent weight was achieved). The organic matter was estimated by looking at the organic carbon in the sediments above the oil spill prior mangrove arrival (establishment horizon)

Herbicide effectiveness under elevated CO2 in controling 14 environmental weed species in Australia

The data was generated in the "Elevated CO2 and herbicide tolerance" experiment (2012). The experiment followed a randomised fully factorial design, with the factors being CO2 concentration (ambient or elevated) and herbicide treatment (recommended and double recommended label rate). Four glasshouses were used: two at the ambient and two at the elevated CO2 concentration. Ten replicates of each weed species for each CO2 × herbicide treatment combination were grown. These were evenly split between the treatment glasshouses. Additionally, six replicates of each weed species were grown under each CO2 treatment to assess the biomass allocation each species at the time of herbicide application. This could not be done after herbicide treatment due to plant mortality. These plants were harvested into their above- and belowground components on the day of herbicide application and oven-dried at 60oC to constant weight (48 – 72 hours) before being weighed. Pots were randomly rearranged within the glasshouses each fortnight to minimise any within-glasshouse effects. All pots were evenly spaced to minimise shading from neighbouring plants. As Lantana camara and I. indica were propagated from cuttings, they were re-potted into 2.8 L pots after eight weeks and six weeks respectively to allow them ample space for root development. The vine species A. cordifolia and I. indica were trained onto stakes. Pots were mist watered for one minute four times daily. The elevated CO2 treatment was maintained by a dosing and monitoring system (Canary Company Pty Ltd, Lane Cove, NSW, Australia) at 550 ppm, from 6 am to 6 pm, with air continuously circulated within each glasshouse. The elevated CO2 treatment represents the predicted atmospheric CO2 concentration by 2030 under most emissions scenarios (IPCC, 2001). The ambient CO2 treatment was 380 ppm. The glasshouse temperature was set to 17°C at night and 24°C during the day
