LiDAR Characterization of Boreal Understory
, 2021 The understory vegetation layer contributes considerably to the physical structure of boreal forests. This research sought to understand the relationships between field- and LiDAR- (light detection and ranging-) derived measures of boreal understory structure. As well as how environmental factors may influence discrepancies that can arise between these

Whole‐seedling trait adjustments of mountain birch under contrasting environmental conditions
Oikos, EarlyView.Warming temperatures can promote arctic tree seedling establishment and growth, but these effects depend on the environmental context and the seedlings' capacity to acquire limiting resources. Here, we tested how temperature, soil properties, and the presence of a neighbouring shrub influence seedling growth rates.

UAV Remote Sensing for Biodiversity Monitoring: Are Forest Canopy Gaps Good Covariates?
Remote Sensing, 2018 Forest canopy gaps are important to ecosystem dynamics. Depending on tree species, small canopy openings may be associated with intra-crown porosity and with space among crowns.

Oikos, EarlyView.Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,

Biomass estimations of invasives Yaupon, Chinese Privet and Chinese Tallow in east Texas Hardwood and Pine Ecosystems [PDF]
, 2017 Forest understory fuels can have profound effects on fire behavior and crown fire initiation. Accurate fire behavior prediction in understory fuels is an essential component for estimating fire intensity and severity during wildfire and prescribed fire ...
