Large Greenhouse Gas Emissions From Drained Peatlands in New Zealand, and the Climate Mitigation Potential of Rewetting Open
Drained peatlands are a substantial contributor to global anthropogenic greenhouse gases despite the relatively small areas they occupy. In New Zealand, drained Organic Soils (former peatlands) under cropland and grazed grasslands dispropo…

Earth's Climate History Explains Life's Temperature Optima Open
Why does the growth of most life forms exhibit a narrow range of optimal temperatures below 40°C? We hypothesize that the recently identified stable range of oceanic temperatures of ~5 to 37°C for more than two billion years of Earth histo…

Dung beetles drive direct and indirect changes in ecosystem multifunctionality Open
Measuring ecosystem multifunctionality (EMF) could be a valuable method for assessing whether nature‐based solutions, such as introducing non‐native species to benefit ecosystem functioning, yield net positive outcomes. While EMF metrics m…

Effects of dairy farming management practices on carbon balances in New Zealand’s grazed grasslands: Synthesis from 68 site-years Open
Globally, the soils underlying managed grasslands are an important reservoir of carbon (C), with the management of the land strongly influencing whether the soils gain, lose or maintain C. Further, improved grassland management, such as ro…

Cooperative Conformational Transitions Underpin the Activation Heat Capacity in the Temperature Dependence of Enzyme Catalysis Open
Many enzymes display non-Arrhenius behavior with curved Arrhenius plots in the absence of denaturation. There has been significant debate about the origin of this behavior and recently the role of the activation heat capacity (ΔC
