Assessing moss transplant methods to enhance Sphagnum moss recovery in post-wildfire hydrophobic peat
<p><strong>Wildfire is the dominant disturbance in northern peatlands and can release large quantities of carbon to the atmosphere through combustion. Post-fire peat hydrophobicity can inhibit moss regeneration, thereby decreasing the potential for post-fire carbon sequestration. To investigate how to enhance post-fire recovery we assessed two moss restoration methods (plugs and fragments) in an Alberta poor fen two and three years following wildfire. P<strong>ost-fire peat hydrophobicity and moss regeneration was characterized in four surface cover types: Severely Burned Feather moss hollows (SB-F), Severely Burned Sphagnum fuscum hummocks (SB-S), Lightly Burned S. fuscum hummocks (LB-S), and Lightly Burned Feather moss lawns (LB-F). We then <strong>conducted experiments testing the success of moss plugs and fragments of varying moss species at LB-F and SB-F surface covers, which had high hydrophobicity and low post-fire moss recovery.</strong></strong></strong></p>

Effect of Hydrophobicity of Fluorescent Carbon Nanoparticles on Transport in Porous Media: Column Experiment Data and Modeling
<p>The data contained here are derived from sand column experiments and modeling which investigate the effects of hydrophobicity on the transport of fluorescent carbon nanoparticles (FCN) in porous media.</p> <p>The data consist of outlet concentrations (relative to the inlet concentrations) of FCN for a suite of experiments testing the recovery of FCN synthesized using four different pyrolysis temperatures(190C, 210C, 230C, and 250C), as well as the recovery of FCN when passed through three different sand types (Fine, Medium, and Coarse). Column experiments were tested under both saturated and unsaturated conditions to investigate the role of pore water content on FCN retention. Finally, results from tests using an inert bromide tracer are also included (File: May_et_al_Column_Experiment_Outlet_Concentrations.xlsx).</p> <p>Additionally, the results from modeling the observed breakthrough curves of FCN are included for three different transport models, as well as modelling results for an inert bromide tracer (File: May_et_al_Breakthrough_Curve_Modeling.xlsx).</p> <p>The raw output files for the two-kinetic sites model that was determined to best reproduce the observed breakthrough curves are also provided (File: May_et_al_Two_Kinetic_Sites_Model_Raw_Output.zip)</p> <p>Finally, the results of sand surface characterization for three sands using a scanning electron microscope are included (File: May_et_al_Sand_Surface_Characterization_SEM-DATA.zip).</p> <p>Please see the following paper for more details: May, D.F., B.

An atomistically informed multiscale approach to the intrusion and extrusion in hydrophobic nanopores
<p>Data from Molecular Dynamics simulations.</p> <p>Files ending in .dat are the "measurement" files and are the files required to compute the free energy and diffusivity from the simulation data. The normal sintax is eqX.dat where X is the imposed filling of the pore. The names of the folders represent the pressure at which the filling was taken (0 MPa, -20 MPa, 60 MPa)</p> <p>We also attach one trajectory file, 0.xyz and one LAMMPS output file, 0.log, which should be enough to reproduce the simulation script, in conjuction with 0.data, the initial condition.</p>

Thallus hydrophobicity: a low-cost method for understanding lichen ecophysiological responses to environmental changes
<p><strong>Premise</strong>: Methods to evaluate lichen thalli hydrophobicity were described in the past, but only recently this was shown to be an important functional trait related to water regulation dynamics that could be used to predict future climate change effects.</p> <p><strong>Methods and Results:</strong> Our protocol requires only a micropipette, distilled water, a tripod and a phone or camera. Hydrophobicity is inferred from multiple metrics associated with absorption times of standardized droplets (initial and total absorption time). We used a dataset of 93 lichen taxa with different growth forms and from different biomes and demonstrated that this method is well suited for capturing different levels of hydrophobicity, including very hydrophilic species.</p> <p><strong>Conclusions</strong>: Our results show that the measurement of lichen hydrophobicity is a rapid and low-cost method to assess an ecophysiologically based lichen functional trait that can be used with almost no limitations, including in different climates, lichen species, and growth forms.</p>

Data from: Developing extruded seed pellets to overcome soil hydrophobicity and seedling emergence barriers
<p>Globally soil water repellency is a major constraint to plant establishment, restricting water infiltration and moisture retention in the seed zone, resulting in poor germination and seedling emergence.</p> <p>To address this problem within an ecosystem restoration context, we investigated the use of a surfactant in extruded seed pellets to improve native plant recruitment in water repellent topsoils of two proteaceous woodland species, <i>Banksia menziesii </i>R.Br (glasshouse trial) and <i>Lambertia inermis </i>R.Br (field trial). In this two-part study, we first examined <i>B. menziesii </i>seedling performance in detail under glasshouse conditions for differences in survival between the extruded pelleting formulations after an induced drought at 12 weeks.</p> <p>We demonstrated that there was no difference in seedling emergence, amongst control seed and pellet treatments in <i>B. menziesii</i>. Initially <i>B. menziesii </i>seedlings emerged faster in the control treatment (non-pelleted control seeds) and had greater initial plant growth (leaf and root production), however by week 12, seedlings generated from pellets were not significantly different from the control seeds, and pellets + surfactant had the greatest number of leaf establishment.</p> <p>Survival after drought of <i>B. menziesii </i>seedlings ranged from 14 to 31 days with pellet + surfactant surviving approximately 2.6 days (11.8%) longer than the control seeds. For the second species, <i>L. inermis</i>,<i> </i>seedling emergence under field conditions was approximately 24% greater in seedlings derived from extruded pellets, however there was no difference in overall survival due to post-emergence predation.</p> <p>This study provides a proof of concept that seedling emergence in water repellent soils can be enhanced with extruded pellets containing surfactants. Our demonstration under <i>in situ</i> and <i>ex situ</i> conditions confirms the prospective use of seed enhancement technologies with future development and field-testing warranted.</p>
