Wood density-climate relationships are mediated by dominance class in black spruce (Picea mariana (Mill.) BSP) [PDF]

open access: yes, 2014
The relationships between climate and wood density components, i.e., minimum ring density, maximum ring density and mean ring density have been studied mainly in dominant trees.

Differences in mycelial turnover and persistence of wood‐decay fungi at the microscale

open access: yesNew Phytologist, Volume 250, Issue 1, Page 577-590, April 2026.
Summary How long do fungal hyphae persist in the environment? And how does this differ between groups and species of fungi? Despite growing knowledge of fungal contributions to decomposition and soil carbon cycles, surprisingly little is known about the turnover of mycelia: What happens to fungal hyphae over time? And how this impacts different fungi's

Legacies from early‐season hot drought: how growth cessation alters tree water dynamics and modifies stress responses in Scots pine

open access: yesPlant Biology, Volume 28, Issue 3, Page 610-621, April 2026.
Early‐season hot drought in Scots pine limits growth and productivity but improves resilience to late‐season drought through reduced water use. Abstract Tree responses to drought are well studied, but the interacting effects of drought timing on growth, water use, and stress legacy are less understood.

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest

open access: yesPlant Biology, Volume 28, Issue 3, Page 622-636, April 2026.
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.

Does Cedrela always form annual rings? Testing ring periodicity across South America using radiocarbon dating

open access: yes, 2017
Tropical tree rings have the potential to yield valuable ecological and climate information, on the condition that rings are annual and accurately dated.

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

open access: yesGlobal Change Biology Communications, Volume 1, Issue 1, March 2026.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Branch Orientation: A Potential Indicator of Stem Rehydration and Water Stress

open access: yesHydrological Processes, Volume 40, Issue 2, February 2026.
Perceptual model illustrating how conifer branch position varies with tree water status. Well‐hydrated trees maintain branches in upward or horizontal positions due to higher water content and turgor pressure. As water stress increases, branches progressively droop downward.

Local Adaptation for Seasonal Cold Tolerance in a High‐Elevation Conifer Species, Subalpine Larch (Larix lyallii Parl.)

open access: yesEvolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Subalpine larch (Larix lyallii Parl.) is a deciduous conifer that only grows at treeline in the Cascade Range and Rocky Mountains of western North America. This habitat is shrinking due to climate change but subalpine larch is unlikely to migrate or adapt in situ and is therefore at risk of maladaptation and eventual extirpation.

Tree defenses, host choice, and reproductive success of a native bark beetle under novel outbreak conditions

open access: yesEcological Applications, Volume 36, Issue 1, January 2026.
Abstract Bark beetles of the genus Dendroctonus are some of the most important disturbance agents in North American forests, having colonized conifers for millions of years. The selection pressure posed by tree‐killing bark beetles pushed trees to develop an arsenal of defensive strategies to which beetles have adapted in their turn.
