Size-specific fecundity and the influence of lifetime size variation upon effective population size in Abies balsamea

, 2000
The hierarchy of plant size often present in dense populations of plants and the close correlation found between size and fecundity can result in an unequal distribution of fecundity, which reduces the ratio of effective population size/census number ...

Effects of adventitious roots on age determination in Balsam fir (Abies balsamea) regeneration

, 2000
The age structure of balsam fir (Abies balsamea (L.) Mill.) regeneration is frequently used to investigate boreal forest dynamics of North America. Tree ages are usually estimated by counting annual growth rings at the shoot-root interface located above

Heating value determination of green and brown balsam fir (Abies balsamea) needles

, 1989
Combustion analysis tests were performed six times (three times for each sample) using a 1341 Plain Oxygen Bomb Calorimeter on air dry green and brown balsam fir (Abies balsamea) needles taken in Frederiction, New Brunswick, Canada to determine their ...

Precontact Use of Balsam Fir (Abies balsamea) in Iowa, USA

Ethnobiology Letters
Excavation of a cave in eastern Iowa (USA) revealed a feature containing charred wood of balsam fir (Abies balsamea) dating to ca. AD 300–400. Taxon identification was based on wood anatomy and species distribution. Balsam fir, a boreal forest species, does not currently grow near the cave but is restricted in Iowa to paleorefugia at algific talus ...

Modifying stomatal conductance delays dehydration but not postharvest needle abscission in Abies balsamea

, 2019
Postharvest needle abscission poses a significant challenge to the balsam fir (Abies balsamea L.) Christmas tree industry. Root detachment, and other postharvest handling and transporting factors, lead to a progressive dehydration leading to postharvest ...

Temporally resolved intra-annual wood density variations in European beech (Fagus sylvatica L.) as affected by climate and aspect

, 2012
We investigated the temporal variability of intra-annual wood density variations in European beech (Fagus sylvatica L.) in a valley in southwestern Germany. Samples were collected from 11 beech trees growing at north-west (NW) and south-west (SW) exposed

Étude phylogéographique pancanadienne du sapin baumier (Abies balsamea [L.] Mill.) et de ses relations avec le sapin subalpin (Abies lasiocarpa [Hook] Nutt.) dans l’ouest du Canada

, 2015
The phylogeographic structure and postglacial history of balsam fir (Abies balsamea) were inferred using mitochondrial DNA (mtDNA) and chloroplast DNA (cpDNA).
