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.

, 1999 1 We used tree ring analysis to determine stem radius and thus examine size variation over time in two even-aged (approximately 40-year-old) mixed populations of black spruce and tamarack established on peatlands in a boreal forest.

Monitoring of historical structural materials with computed tomography
Structural Concrete, EarlyView.Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Journal of Wood Science, 2020 Cross-laminated timber (CLT) is an innovative engineering wood product made by gluing layers of solid-sawn lumber at perpendicular angles. The commonly used wood species for CLT manufacturing include spruce-pine-fir (SPF), douglas fir-larch, and southern

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects
Wildlife Biology, EarlyView.Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

What Drives Reproductive Maturity and Efficiency in Serotinous Boreal Conifers?
Frontiers in Ecology and Evolution, 2022 In boreal North America, much of the landscape is covered by fire-adapted forests dominated by serotinous conifers. For these forests, reductions in fire return interval could limit reproductive success, owing to insufficient time for stands to reach ...

, 2004 Black spruce and tamarack are the predominant tree species in boreal peatlands. The effects of flooding on morphological and physiological responses were investigated in greenhouse grown (18 months old) black spruce (Picea mariana) and tamarack (Larix ...
