Tree regeneration characteristics in limestone forests of the Cat Ba National Park, Vietnam

BMC Ecology and Evolution, 2022
Background The ability of overstory tree species to regenerate successfully is important for the preservation of tree species diversity and its associated flora and fauna.

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

International 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

Ecology 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

Plants, 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

Ecology 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.

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

Ecology 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.

Fire-induced shifts in overstory tree species composition and associated understory plant composition in Glacier National Park, Montana

Plant Ecology, 2012
In Rocky Mountain forests, fire can act as a mechanism of change in plant community composition if postfire conditions favor establishment of species other than those that dominated prefire tree communities. We sampled pre and postfire overstory and postfire understory species following recent (1988–2006) stand-replacing fires in Glacier National Park (

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

Silva 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).

Facilitation differentially affects competitive responses of aspen and subalpine fir through stages of stand development

Ecosphere, 2022
Spatial interactions between trees influence forest community succession. The objective of this study was to investigate how shifts in forest composition and proximity between tree species affect stand development over time in mixed forest systems.
