Species differentiation of North American spruce (Picea) based on morphological and anatomical characteristics of needles

open access: yes, 2000
Differentiation of most North American spruce (Picea) species can be done based on needle morphology and anatomy. Picea breweriana S. Watson, Picea chihuahuana Martìnez, Picea mariana (Mill.) BSP, Picea martinezii Patterson, and Picea rubens Sarg ...

Conservative Spruce Outperforms Acquisitive Larch Under Warming and CO2

open access: yesGlobal Change Biology, Volume 32, Issue 10, October 2026.
The acquisitive strategy of larch supports high transpiration and nitrogen uptake, facilitated by anatomical shifts, increased VPD, and soil warming. In contrast, the conservative strategy of spruce maintains greater hydraulic safety than larch, contributing to higher survival and lower climate sensitivity under future warming.

A Molecular Identification Protocol for Roots of Boreal Forest Tree Species

open access: yesApplications in Plant Sciences, 2014
Premise of the study: Roots play a key role in many ecological processes, yet our ability to identify species from bulk root samples is limited. Molecular tools may be used to identify species from root samples, but they have not yet been developed for ...

Prophylactic Inhalation of Bergamot Essential Oil Ameliorates Hormone‐Simulated Pseudopregnancy Withdrawal‐Induced Postpartum Depression by Modulating Hippocampal Synaptic Plasticity

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 20, October 2026.
ABSTRACT Postpartum depression (PPD) affects approximately 17.2% of women giving birth globally, but current pharmacotherapies face significant limitations including invasive intravenous delivery (brexanolone) and high costs Bergamot essential oil (BEO) has demonstrated efficacy in aromatherapy for depression, yet its role in PPD remains unexplored ...

Transition from Juvenile to Mature Wood in Black Spruce (Picea Mariana (Mill.) B.S.P.) [PDF]

open access: yes, 2007
The radial patterns of several intra-ring traits in increment cores of black spruce (Picea mariana (Mill.) B.S.P.) plantation trees were modeled with polynomials to characterize their trends and to estimate the transition age from juvenile to mature wood.

Facilitation of Balsam Fir by Trembling Aspen in the Boreal Forest: Do Ectomycorrhizal Communities Matter?

open access: yesFrontiers in Plant Science, 2019
Succession is generally well described above-ground in the boreal forest, and several studies have demonstrated the role of interspecific facilitation in tree species establishment.

Resilience or reassembly: Wildfire–vegetation dynamics in rapidly warming subarctic forests of northwestern Canada

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Climate‐induced shifts in disturbance regimes are reshaping northern forest ecosystems, where tree species are at their geographic range limit. Northern Canada has warmed over twice as much as the mean global increase since 1950, providing a critical context to study climate–fire–vegetation interactions under rapid warming.
