Balsam fir (Abies balsamea) needles and their essential oil kill overwintering ticks (Ixodes scapularis) at cold temperatures [PDF]

open access: yesScientific Reports, 2022
The blacklegged tick, Ixodes scapularis, vectors Borrelia burgdorferi, a bacterium that causes Lyme Disease. Although synthetic pesticides can reduce tick numbers, there are concerns about their potential effects on beneficial insects, such as ...

Do Abies religiosa Seedlings That Survived Hot/Dry Range‐Edge Conditions Exhibit Genetic Evidence of Selection? [PDF]

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
In a common garden experiment of sacred fir (Abies religiosa), nearly all seedlings planted at 3400 and 3000 m survived, but only 6% survival at 2600 m (representing possible warmer and drier future conditions). When comparing low elevation survivors to higher elevation seedlings representing the initial population, PCAdapt identified 2202 outlier SNPs

Unearthing Forest History: Integrating Soil Charcoal Macrofossils and Pollen Reveals Delayed Forest Responses to Holocene Climatic Transitions in Boreal–Temperate Ecotone [PDF]

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study reconstructs long‐term vegetation dynamics at the boreal–temperate forest ecotone in eastern Canada using soil charcoal, pollen records, and forest inventories. Results reveal a delayed expansion of thermophilous tree species and a late borealization of the landscape in relation to climate change, alongside recent stand‐scale shifts driven ...

Wood formation in Abies balsamea seedlings subjected to artificial defoliation [PDF]

open access: yesTree Physiology, 2009
We determined the cambial sensitivity and quantified the anatomical differences in xylem of Abies balsamea (L.) Mill. seedlings subjected to artificial defoliation to simulate spruce budworm feeding. Defoliation was performed by removing two-thirds of needles of all current-year shoots for up to four consecutive growth cycles to account for inter- and ...

Abibalsamins A and B, Two New Tetraterpenoids from Abies balsamea Oleoresin [PDF]

open access: yesOrganic Letters, 2012
Abibalsamins A (1) and B (2), two unprecedented tetraterpenoids featuring a 3,4-seco-rearranged lanostane system fused with a β-myrcene lateral chain via a [4 + 2] Diels-Alder cycloaddition, were isolated from the oleoresin of Abies balsamea. Their structures were elucidated by means of extensive 2D NMR, IR, and MS spectroscopy analyses.

Effect of Pyroligneous Acid on Needle Retention and Certain Stress-Related Phytochemicals in Balsam Fir (Abies balsamea) [PDF]

open access: yesPlants
Balsam fir is an important specialty horticultural crop in eastern North America and commonly harvested for use as Christmas trees. Postharvest quality is a major challenge for producers, who are particularly concerned about postharvest needle retention.

Species‐level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees [PDF]

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3221-3237, September 2026.
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to

Cis-abienol from tobacco trichomes to ambergris-like compounds: advances in biosynthesis, fermentation, and industrial applications [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology
Cis-abienol is found in small quantities in plants like Nicotiana tabacum and Abies balsamea. It serves as a precursor for the synthesis of ambergris-like compounds, including ambroxide and ambreinolide, which are highly valued in the perfume industry ...

A qPCR assay for the detection of Phytophthora abietivora, an emerging pathogen on fir species cultivated as Christmas trees. [PDF]

open access: yesPLoS ONE
Emerging species of the Phytophthora genus are among the most important threats to global plant biodiversity, horticulture and trade. For instance, Phytophthora root rot (PRR) of Christmas trees, mainly Fraser (Abies fraseri) and balsam (Abies balsamea ...
