Moose indifferent to canopy loss from forest disturbance by bark beetles

The Journal of Wildlife Management, EarlyView.
Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

LiDAR shows that higher forests have more slender trees [PDF]

, 2012
High-density Airborne Laser Scanning was used to derive the Canopy Height Model (CHM) of an experimental forest site in the neotropics (Paracou, French Guiana).

Boundary-layer flow within and above a forest canopy of variable density

, 2012
An analytical model is developed for flow within and above a forest canopy with a slowly varying canopy density. Results are compared with existing analytical models for flow over a surface with slowly varying roughness length, and also with numerical ...

Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas

The Journal of Wildlife Management, EarlyView.
Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.

Canopy uptake dominates nighttime carbonyl sulfide fluxes in a boreal forest [PDF]

, 2017
Nighttime vegetative uptake of carbonyl sulfide (COS) can exist due to the incomplete closure of stomata and the light independence of the enzyme carbonic anhydrase, which complicates the use of COS as a tracer for gross primary productivity (GPP).

Predicting woodpecker damage in utility infrastructure in the southeastern United States using species distribution modeling

The Journal of Wildlife Management, EarlyView.
Predicting areas of wildlife damage can reduce long‐term costs. We developed and tested models of the geographic distribution of damage by woodpeckers to utility infrastructure and delineated areas of greater importance. Abstract Predicting areas of wildlife damage to human development has the potential to reduce long‐term costs associated with ...

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Using airborne lidar to discern age classes of cottonwood trees in a riparian area [PDF]

, 2006
Airborne lidar (light detecting and ranging) is a useful tool for probing the structure of forest canopies. Such information is not readily available from other remote sensing methods and is essential for modern forest inventories.
