Scaling copepod grazing in a coastal upwelling system: the importance of community size structure for phytoplankton C flux
The study demonstrates that copepod grazing is a size-dependent process where communities dominated by small-sized species significantly increase the efficiency of carbon transfer from phytoplankton compared to communities dominated by larger species.

Modelling crop yield ozone
The study finds that accelerated leaf senescence is the primary mechanism by which ozone pollution reduces crop yield, rather than direct impairment of photosynthesis in un-senesced leaves. It concludes that the Phytotoxic Ozone Dose (POD), based on stomatal O3 flux, is a more accurate predictor of physiological response than 24-hour mean concentrations or AOT40.

Processes controlling DOC in pore water during simulated drought cycles in six different UK peats
The study found that dissolved organic carbon (DOC) concentrations in UK peatlands decrease during drought due to acidification, as measured by acid neutralising capacity (ANC), rather than being primarily driven by soil biota.

Soil respiration: implications of the plant-soil continuum and respiration chamber collar insertion depth on measurement and modelling of soil CO2 efflux rates in three ecosystems
The study finds that inserting soil collars, even by a few centimetres, consistently underestimates total soil CO2 efflux by severing surface roots, with the magnitude of the reduction depending on the ecosystem's root distribution and the depth of insertion.
