Species Distribution Models and Abundance Estimates Enhance Breeding Bird Atlas Data
Ecology and Evolution, Volume 16, Issue 6, June 2026.Our primary goal was to leverage the large amount of systematic and volunteer‐based data produced by the Minnesota Breeding Bird Atlas to develop species distribution models and population estimates for as many breeding bird species as possible. We utilized three complementary techniques to develop species distribution models and maps for 136 breeding ...

Effects of harvest treatments on spruce budworm, Choristoneura fumiferana (Clem.) (lepidoptera: Tortricidae), dispersal within forest stands [PDF]
, 1996 Dispersal is a critical trait during the life history of the spruce budworm, Choristoneura fumiferana (Clem.), which leads to its widespread infestation and damage.

Survival-time analysis of white spruce during spruce budworm defoliation
Silva Fennica, 2005 Mortality and defoliation (DF%) in 987 white spruce (Picea glauca (Moench) Voss) trees were followed from 1992 to 2003 during an outbreak of the spruce budworm Choristoneura fumiferana (Clem.) in 15 white-spruce-dominated uneven-aged stands in the ...

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 ...

Frontiers in Ecology and EvolutionUnderstanding the historical variability in the disturbance dynamics of the most important defoliator in eastern Canada, the spruce budworm (SBW), throughout its range will be paramount in anticipating potential changes associated with current climate ...

Ecosphere, 2018 Although landscape spatial structure is known to influence spatial patterns of biodiversity, its effect on insect communities at higher trophic levels such as parasitoids remains poorly understood.

Ecology of outbreak populations of the western spruce budworm
Ecosphere, 2021 We sampled outbreak populations of western spruce budworm, Choristoneura occidentalis (Lepidoptera: Tortricidae), between 1997 and 2016 in Douglas‐fir forests in the interior of British Columbia, Canada.

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 ...

Site-infidelity by budworm-linked warblers at the edge of an area defoliated by spruce budworm
Avian Conservation and Ecology, 2021 Most songbird species show some degree of fidelity to their previous breeding location, especially after successful reproduction. However, species associated with highly dynamic food sources (e.g., outbreaking insects) may have to adopt more flexible ...

Entire solutions of the spruce budworm model
Advances in Difference Equations, 2018 This paper is concerned with the entire solutions of the spruce budworm model, i.e., solutions defined for all (x,t)∈R2 $(x,t)\in \mathbb{R}^{2}$. Using the comparison argument and sub-super-solution method, three types of the entire solutions are ...
