Potential Species Distribution of Balsam Fir Based on the Integration of Biophysical Variables Derived with Remote Sensing and Process-Based Methods

Remote Sensing, 2009
In this paper we present a framework for modelling potential species distribution (PSD) of balsam fir [bF; Abies balsamea (L.) Mill.] as a function of landscape-level descriptions of: (i) growing degree days (GDD: a temperature related index), (ii) land ...

A review of climate change effects on the regeneration dynamics of balsam fir

The Forestry Chronicle, 2022
Balsam fir (Abies balsamea) is one of the most abundant softwood species in eastern Canada but is projected to be adversely affected by climate change.

Glacial refugia, postglacial dynamics, and hybrid zones of Pinaceae in Eurasia captured from sedimentary ancient DNA

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Boreal forests cover nearly one‐third of global forest area. Glacial cycles have shaped the distribution and connectivity of modern Pinaceae genera, yet species‐level refugia, postglacial migrations, and hybridization patterns remain unclear due to limited high‐resolution taxonomic and temporal data. We applied a hybridization capture approach

Effective Conservation Decisions Require Models Designed for Purpose: A Case Study of Boreal Caribou in Ontario's Ring of Fire

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Decision making in conservation science often relies on the best available information, but existing models are rarely reproducible, transferrable, or accessible. We sought to reproduce and evaluate the suitability of the two best available models for predicting impacts of proposed mining on boreal woodland caribou (Rangifer tarandus caribou) in ...

Element microdistribution in the bark of Abies balsamea and Picea rubens and its impact on epiphytic lichen abundance on Whiteface Mountain, New York

, 2003
Epiphytic lichen cover and total element concentrations of bark were studied in it montane Abies balsamea-Picea rubens forest on Whiteface Mountain in upstate New York. Epiphytic lichen abundance was much higher on A. balsamea compared to P. rubens.

Effects of Wood Species on the Energy Requirements and Size Distribution of Strands Produced by a Strander-Canter

BioResources, 2023
The effects of wood species on the performance of the strander-canting process were studied. Logs of balsam fir (Abies balsamea (L.) Mill.), black spruce (Picea mariana (Mill.) B.S.P.), and jack pine (Pinus banksiana Lamb) were processed under two ...

Integrating historical observations alters projections of eastern North American spruce–fir habitat under climate change

Ecosphere, 2022
Spruce–fir (Picea–Abies) forests of the North American Acadian Forest Region are at risk of disappearing from the northeastern United States and Canada due to climate change.

Description of the five variants (mitotypes) detected in the intron 4 of the nad5 mtDNA gene of Abies balsamea. Abies fraseri and Abies lasiocarpa, two phylogenetically closely-related species to A. balsamea, were fixed for mitotype I and mitotype 2, respectively.

Tree communities face rising soil water deficits exposure under projected climate change in northern temperate forests

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Soil water deficits in temperate forests are projected to become more frequent, more severe, and longer in duration. This study aims to quantify the current (1981–2010) and projected (2041–2070) exposure of 17 tree communities to soil water deficit (severity and duration) in southwestern Quebec, Canada, using the Canadian Land Surface Scheme ...

Delphinella balsameae Tip Blight of Abies lasiocarpa in Vermont

Plant Disease, 1997
In 1996, a windbreak planting of Abies concolor (Gordon & Glend.) Lindl. ex Hildebr. and A. lasiocarpa (Hook.) Nutt. on a Christmas tree farm in Lamoille County, VT, incurred tip blight caused by a Delphinella sp. Although only scattered new shoots of the intermixed A. concolor and nearby A. balsamea (L.)
