Spider assemblages in the overstory, understory, and ground layers of managed stands in the western boreal mixedwood forest of Canada

, 2011
: Logging is the main human disturbance in the boreal forest; thus, understanding the effects of harvesting practices on biodiversity is essential for a more sustainable forestry.

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

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.

A Comparison of Mobile Laser Scanning Data Acquisition Methods in Closed Forest, Open Woodland and Sub‐Alpine Woodland Ecosystems

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 ...

Comprehensive evaluation of global CI, FVC, and LAI products and their relationships using high-resolution reference data

Science of Remote Sensing, 2022
In recent decades, several global clumping index (CI), fractional vegetation cover (FVC), and leaf area index (LAI) products have been generated using a range of optical satellite sensors.

Water relations of pine seedlings in contrasting overstory environments

, 2009
Overstory conditions influence understory microclimate and resource availability, leading to gradients in evaporative demand and moisture availability that influence seedling water relations. Partial canopies may either reduce seedling moisture stress by

Wild Pigs (Sus scrofa) Stand Their Ground: Investigating Flight Response, or Lack Thereof, to Perceived Predation Risk 野猪坚守原地:探究其面对感知捕食风险时的逃逸反应 (或无逃逸行为)

Wildlife Letters, EarlyView.
We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Regional-scale data assimilation with the Spatially Explicit Individual-based Dynamic Global Vegetation Model (SEIB-DGVM) over Siberia

Progress in Earth and Planetary Science, 2021
This study examined the regional performance of a data assimilation (DA) system that couples the particle filter and the Spatially Explicit Individual-based Dynamic Global Vegetation Model (SEIB-DGVM).

The singing phenology of Bachman's sparrow: implications for monitoring programs

Wildlife Society Bulletin, EarlyView.
We used automated recording units, weather data, and multiple logistic regression with generalized estimating equations to determine the annual singing period and influences on singing behavior of Bachman's sparrow in Texas, USA, surveying daily for 2 years.

Effects of forest treatments on nutritional carrying capacity for white‐tailed deer in mid‐rotation loblolly pine stands

Wildlife Society Bulletin, EarlyView.
In this study we compared nutritional carrying capacity (NCC) for white‐tailed deer (Odocoileus virginianus) among 6 treatment combinations in mid‐rotation loblolly pine (Pinus taeda) forests, including 3 levels of commercial thinning. We also paired each level of thinning with prescribed fire, prescribed fire with herbicide, or herbicide only ...
