Remote Sensing in Ecology and Conservation, EarlyView.This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Trophic interactions and feedbacks maintain intact and degraded states of Hawaiian tropical forests
Ecosphere, 2022 Feedbacks within ecosystems can lead to internal reinforcement of the current state providing ecosystem resilience. Often, multiple biotic interactions across trophic levels play a role in such feedbacks, yet these are generally studied independently ...

Acta Botânica Brasílica, 2022 The importance of understory vegetation cannot be denied as an integral component of forest ecosystems, but there is a dearth of studies to explore the effects of environmental variables and canopy species on its diversity and composition.

Remote Sensing in Ecology and Conservation, EarlyView.This study demonstrates that the mobile laser scanning (MLS) sampling density required to reliably characterise vegetation structure increases with a site's structural complexity. Applying a five‐level acquisition framework across open woodland, closed forest and sub‐alpine woodland ecosystems, we found that longer scanning paths increased the ...

Relationships Between Overstory and Understory Tree Composition and Light Environment in an Old Growth Forest, Adirondacks, NY [PDF]
, 2013 Density of tree seedlings and saplings can be considerably influenced by light availability and the overstory canopy composition. We examined whether forest understory light environment could be predicted by overstory composition in an old growth ...

Agricultural and Forest Entomology, EarlyView.The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

No Cocoa Without Deforestation? A Field‐Type Analysis of Forest Frontiers in West Africa
Journal of Agrarian Change, EarlyView.ABSTRACT This paper analyses the interrelations of production systems, class relations and deforestation in a smallholder forest frontier. Using the concept of field types, we provide a plot‐level analysis of deforestation processes in West Africa, where smallholders convert forest into cocoa farms.

Assessing working lands as habitat for disturbance‐dependent birds using autonomous recording units
Restoration Ecology, EarlyView.Abstract Introduction Working lands can provide habitat for declining disturbance‐dependent birds, such as Bachman's Sparrow (Peucaea aestivalis) and Northern Bobwhite (Colinus virginianus), but it remains unclear whether restoration following intensive land use (e.g. surface mining) yields habitat comparable to less intensive land uses (e.g.

Influence of fire, logging, and overstory composition on understory abundance, diversity, and composition in boreal forests, Ontario Canada [PDF]
, 2006 Study area : Northwestern OntarioUnderstory vegetation is the most diverse and least understood component of North American boreal forests and are important as they influence overstory succession and nutrient cycling. The objectives of this thesis were

Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content
Fire and Materials, Volume 50, Issue 7, Page 752-770, November 2026.ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...
