LiDAR-derived forest inventory data to map and quantify ecologically important large trees across large spatial extents. [PDF]
Ecol ApplAbstract Large old trees are widely recognized as ecologically important across forest landscapes and concern regarding the decline of these trees is well documented because of their role in maintaining biodiversity for a broad range of organisms. In response to a growing need to inventory such trees, we developed and present the methodology to map and

Defensive Traits during White Spruce (Picea glauca) Leaf Ontogeny
Insects, 2021 Changes during leaf ontogeny affect palatability to herbivores, such that many insects, including the eastern spruce budworm (Choristoneura fumiferana (Clem.)), are specialist feeders on growing conifer leaves and buds.

Moose indifferent to canopy loss from forest disturbance by bark beetles
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

Insects, 2015 White spruce (Picea glauca (Moench) Voss) trees that are resistant or susceptible to spruce budworm (Choristoneura fumiferana (Clem.)) attack were identified in a southern Quebec plantation.

Variation of Stem Radius in Response to Defoliation in Boreal Conifers
Frontiers in Forests and Global Change, 2021 In the long term, defoliation strongly decreases tree growth and survival. Insect outbreaks are a typical cause of severe defoliation. Eastern spruce budworm (Choristoneura fumiferana Clem.) outbreaks are one of the most significant disturbances of Picea

Anthropogenic disturbance and trophic interactions mediate population viability of American martens
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.We present a simulation model of the probability of collapse to <10% of carrying capacity for American marten populations over a 50‐year time frame in relation to forest disturbance due to commercial harvesting and fur‐trapping levels. Probability of collapse differed between models that assumed no effect of logging (solid line), martens living in a ...

Budworm-linked warblers as early indicators of defoliation by spruce budworm: A field study
Ecological Indicators, 2021 Outbreaks of eastern spruce budworm (Choristoneura fumiferana; hereafter SBW) are a major natural disturbance in coniferous forests of eastern North America. These outbreaks provide a superabundant source of food for insectivorous birds.

Oikos, Volume 2026, Issue 5, May 2026.Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.
