Land-use history impacts spatial patterns and composition of woody plant species across a 35-hectare temperate forest plot [PDF]

open access: yesPeerJ, 2022
Land-use history is the template upon which contemporary plant and tree populations establish and interact with one another and exerts a legacy on the structure and dynamics of species assemblages and ecosystems.

Dynamic stratification for vertical forest structure using aerial laser scanning over multiple spatial scales

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2022
The distinct vertical structure (i.e., “overstory-understory-grass”) in natural forest stand causes significant differences in species composition, carbon–water cycles, and phenology variations in different vertical layers.

Modeling Forest Succession among Ecological Land Units in Northern Minnesota

open access: yesEcology and Society, 1998
Field and modeling studies were used to quantify potential successional pathways among fine-scale ecological classification units within two geomorphic regions of north-central Minnesota.

Western Spruce Budworm Effects on Forest Resilience

open access: yesPlants, 2022
Western spruce budworm (Choristoneura freemani Razowski) is the most destructive defoliator of forests in the western US. Forests in northern New Mexico experienced high levels of WSBW-caused defoliation and subsequent mortality between the 1980s and ...

Which demographic processes control competitive equilibria? Bayesian calibration of a size‐structured forest population model

open access: yesEcology and Evolution, 2023
In forest communities, light competition is a key process for community assembly. Species' differences in seedling and sapling tolerance to shade cast by overstory trees is thought to determine species composition at late‐successional stages.

Aspen forest overstory relations to understory production [PDF]

open access: yes, 2011
We examined the relationship between aspen cover and understory production across two topographic positions and two management systems within the Aspen Parkland of eastern Alberta.

Habitat characteristics and climatic factors influence microhabitat selection and arthropod community structure in a globally rare central Appalachian shale barren

open access: yesEcology and Evolution, 2021
The central Appalachian shale barrens, a globally unique habitat type restricted to the eastern United States, presents an insular and physiologically stressful environment with sparse vegetation and extreme ground surface and air temperatures.

Influence of forest composition on understory cover in boreal mixedwood forests of western Quebec

open access: yesSilva Fennica, 2002
Forest overstory composition influences both light and nutrient availability in the mixed boreal forest. The influence of stand composition on understory cover and biomass was investigated on two soil types (clay and till deposits).
