Multi-scale relationship between peatland vegetation type and dissolved organic carbon concentration
Dissolved organic carbon (DOC) is a key component of the carbon cycle and has significant impacts on aquatic ecosystems and potable water treatment. Upward trends in river and lacaustrine DOC concentrations have been observed and a number of key drivers have been proposed. Here, we present DOC concentration data from plot scale pore waters at one site and surface water from artificial drains sampled within a national survey which demonstrate a significant correlation between peatland vegetation type and DOC concentration. Calluna dominance was associated with the highest DOC concentration, Molinia and Sphagnum dominance with lower concentrations, and sedge dominance with intermediate concentrations. Water sampled from drains dominated by Calluna had greater DOC concentrations than water sampled from pore waters in plots dominated by Calluna. In contrast DOC concentrations from plots dominated by sedges were greater than those sampled from drains dominated by sedges. We discuss these findings in relation to plant functional traits and their influence on the physical and biotic conditions that regulate DOC concentrations. Given the known effects of management activities and climate change on peatland vegetation composition there is potential to manage plant community composition to ameliorate the observed rising DOC concentration.

Minimum Information about a Cardiac Electrophysiology Experiment (MICEE): Standardised reporting for model reproducibility, interoperability, and data sharing
Cardiac experimental electrophysiology is in need of a well-defined Minimum Information Standard for recording, annotating, and reporting experimental data. As a step towards establishing this, we present a draft standard, called Minimum Information about a Cardiac Electrophysiology Experiment (MICEE). The ultimate goal is to develop a useful tool for cardiac electrophysiologists which facilitates and improves dissemination of the minimum information necessary for reproduction of cardiac electrophysiology research, allowing for easier comparison and utilisation of findings by others. It is hoped that this will enhance the integration of individual results into experimental, computational, and conceptual models. In its present form, this draft is intended for assessment and development by the research community. We invite the reader to join this effort, and, if deemed productive, implement the Minimum Information about a Cardiac Electrophysiology Experiment standard in their own work.T.A. Quinn... D.A.
