Intraspecific and environmental variation mediate seed finding effectiveness among scatter‐hoarding small mammals

Ecology, Volume 107, Issue 3, March 2026.
Abstract About half of all plant species rely on animals such as scatter‐hoarding small mammals for seed dispersal. These plants include many keystone species for which small mammals are key primary and secondary dispersal agents as well as seed predators.

Incipient Speciation Amongst Abies balsamea on Mount Moosilauke, New Hampshire

, 2019
Like other conifers Abies balsamea (L.) Mill. is pollinated by wind, but how pollen moves among populations, affecting local genetic variation, has not been studied.

Pathogenicity tests of Gremmeniella abietina var. balsamea isolated from balsam fir in Canada

, 2010
The pathogenicity of Gremmeniella abietina var. balsamea isolated from balsam fir (Abies balsamea) was tested on different conifer hosts, including A. balsamea. Pathogenicity of the fungus was positive on balsam fir only.

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

Global 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.

Temporal pattern in basal area prediction error of a growth model for Quebec’s temperate forest

The Forestry Chronicle, 2020
Pour les utilisateurs, l’évaluation des performances et de la fiabilité d’un modèle de croissance est essentielle. Cependant, les biais spécifiques à l’espèce et à l’année d’observation sont rarement signalés, bien que des changements dans les conditions

Effects of habitat quality and fine‐scale spatial structure on epiphytic lichen and bryophyte communities

Journal of Ecology, Volume 114, Issue 3, March 2026.
Host‐tree identity, particularly bark physico‐chemical traits, emerged as the dominant driver of epiphytic lichen and bryophyte community composition in this closed‐canopy temperate forest system, while microclimate plays a subordinate role. Spatial structure and proximity contributed additional effects for both groups, but for lichens, habitat ...

Variation in reproductive potential across a multi-species treeline

Arctic, Antarctic, and Alpine Research, 2018
Cone and seed production at the forest-tundra ecotone, or treeline, depend on species-specific tolerances to limiting abiotic and biotic factors. As range expansion via seed dispersal is needed to keep pace with climate change, reproductive limitations ...

Boreal tree regeneration after fire and fuelwood harvesting in coastal Nunatsiavut

Arctic Science, 2020
Consecutive landscape-scale disturbances are known to influence boreal forest regeneration, yet few published data exist on the compounding effects of natural and anthropogenic disturbance on regeneration in subarctic forests.

The effects of timing and of six growth regulators on the rooting of Abies stem cuttings in east-central Indiana and the initiation of callus tissue of Abies concolor by tissue culture techniques

, 1970
The purpose of this study was twofold. The first purpose was to determine the time of year when representative Abies stem cuttings will root most successfully in east-central Indiana.
