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…

Mutations in <i>RNU4ATAC</i> Are Associated With Chilblain‐Like Lesions and Enhanced Type I Interferon Signalling Open
Mutations in the non-coding RNA gene RNU4ATAC are associated with growth restriction and complications related to antibody deficiency. Here, we report that innate immune dysfunction is a previously unrecognised feature of this disorder. In…

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…

Peatland evaporation across hemispheres: contrasting controls and sensitivity to climate warming driven by plant functional types Open
Peatlands store disproportionally large amounts of carbon per unit area, a function that is dependent on maintaining high and stable water tables. Climate change is likely to negatively impact carbon storage in peatlands, in part due to in…

Isohydric stomatal behaviour alters fruit vascular flows and minimizes fruit size reductions in drought-stressed ‘Hass’ avocado (<i>Persea americana</i> Mill.) Open
Background and Aims Plant water status is important for fruit development, because many fleshy fruits contain large amounts of water. However, there is no information on vascular flows of Persea americana ‘Hass’ avocado. The aims of this r…

Upscaling Wetland Methane Emissions From the FLUXNET‐CH4 Eddy Covariance Network (UpCH4 v1.0): Model Development, Network Assessment, and Budget Comparison Open
Wetlands are responsible for 20%–31% of global methane (CH 4 ) emissions and account for a large source of uncertainty in the global CH 4 budget. Data‐driven upscaling of CH 4 fluxes from eddy covariance measurements can provide new and in…

The role of the peat seed bank in plant community dynamics of a fire‐prone New Zealand restiad bog Open
New Zealand restiad bogs have histories of natural fire, which is reflected in the presence of plant species with adaptations such as serotiny and fire‐stimulated flowering. The possibility of fire‐cued germination has not been investigate…
