Alleviation of phosphorus rather than nitrogen limitation driven by permafrost and landscape effects on Dahurian larch forests

Functional Ecology, Volume 40, Issue 8, Page 2590-2601, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

Panel statement on young pine plants used for afforestation or reforestation as pathway for pinewood nematode (PWN) Bursaphelenchus xylophilus

EFSA Journal, Volume 24, Issue 8, August 2026.
Abstract Pinewood nematode (PWN) (Bursaphelenchus xylophilus) is a destructive pest of Pinus trees worldwide which depends for transmission on the cerambycid insects of the genus Monochamus. EFSA was asked to assess the potential role of young host plants for afforestation or reforestation planting as a pathway for PWN. According to legislation (EU COM/

Simulated CO2 Fertilization Drives Progressive Phosphorus Limitation via Accelerated Organic Cycling in Amazonian Forests

Global Change Biology, Volume 32, Issue 7, July 2026.
Rising atmospheric CO2 increases phosphorus demand in Amazon forests. Using a microbial‐explicit land model in low and high phosphorus Amazonian forest sites, we show that low‐phosphorus forests increasingly rely on organic phosphorus cycling to sustain productivity.

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Population Status and Recovery Potential of Dalbergia odorifera Under Anthropogenic Disturbance: Evidence From Hainan Island, China

Ecology and Evolution, Volume 16, Issue 6, June 2026.
To explore the survival status and dynamics of wild populations of Dalbergia odorifera on Hainan Island, this study adopts field sampling combined with demographic analysis such as age class division and life table analysis. Results show that although the population is of growing type with abundant young individuals, there are structural gaps and false

Community dynamics of lignicolous lichens on standing deadwood in a 275‐year chronosequence

Oikos, Volume 2026, Issue 6, June 2026.
Dead trees provide discrete habitat patches in which patch quality changes gradually due to wood decomposition. Although in most cases these patches persist for not more than a few decades, in some ecosystems deadwood decomposition and the consequent change in habitat patch quality can be a centuries‐long process, potentially leading to dynamics of ...
