Climate Controls on Carbon Dioxide Fluxes in a High‐Elevation Grassland
Global Change Biology Communications, Volume 1, Issue 2, June 2026.Climate change is significantly influencing high‐elevation grasslands, possibly unbalancing CO2 exchanges and the sink‐source dynamics. Cumulated heat available for plant growth and vegetation cover were identified as the main controllers of phenological development and, via direct or mediated effects, of CO2 fluxes (ER and GPP).

A New and Minuscule Annual Species of Montia (Montiaceae) From Alpine Fens in Otago, New Zealand
New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.Montia minuscula Heenan is recognised as a new species from alpine habitats in Otago, South Island, New Zealand. It is currently known from only two locations, one in the Old Man Range (Kopuwai Conservation Area) and another in The Remarkables. It grows in palustrine fens that are associated with groundwater seepage such as from snowmelt and snowbanks.

Lachnaceae (Helotiales, Leotiomycetes) of New Zealand—An Introduction
New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.This is the first of a planned series of articles on the taxonomy and diversity of Lachnaceae (Leotiomycetes, Helotiales) of New Zealand. Based largely on specimens from the New Zealand Fungarium (Te Kohinga Hekaheka o Aotearoa) (PDD) that have DNA sequences available, this paper provides a brief survey of the New Zealand species present in each of the

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site
Oikos, Volume 2026, Issue 6, June 2026.Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Response of specific leaf area to light: comparative study of a large species set
Oikos, Volume 2026, Issue 6, June 2026.Specific leaf area (SLA) is a commonly used proxy for the leaf economy spectrum in plants, separating species with low‐cost leaves (in terms of carbon) with short lifespan and hence fast turnover from species with high‐cost and long‐lived leaves. While SLA is used mainly for interspecific comparisons, it also varies within species both ontogenetically ...

People and Nature, Volume 8, Issue 6, Page 1572-1587, June 2026.Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract The microtopography of the Arctic tundra and the associated soil moisture (SM) gradient influence the net ecosystem‐atmosphere exchange of methane (CH4) and carbon dioxide (CO2). To quantify fine‐scale variability in a permafrost ecosystem, we measured growing‐season carbon fluxes with closed chambers at Trail Valley Creek, Canada from 2022 to

Soil Physical Properties in Estimating the CO2 Emissions in Drained Peatland Forests
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract Peatland drainage aims at enhancing tree growth by improving soil aeration and nutrient availability through the lowering of water table, but it also accelerates peat decomposition and increases CO2 emissions. CO2 emission estimates of drained peatlands are typically based on surface‐level measurements, whereas studies on peat decomposition ...
