Modeling effects of environmental conditions and hunter activity on Montezuma quail harvest in Arizona

open access: yesThe Journal of Wildlife Management, EarlyView.
Models of spatiotemporal variation in hunter harvest show that monsoon precipitation and changes in hunter behavior and composition are the primary drivers underlying variation in annual harvest of Montezuma quail. The demographic structure of the previous year's harvest was also strongly associated with the magnitude and rate of annual harvest ...

A Comprehensive Evaluation of Simulating Thermal Conductivity in Oak Wood Using XCT Imaging

open access: yes
Wood drying is the most critical and energy-intensive process in the wood industry. However, the complex pore structure of wood significantly affects its thermal performance. Therefore, it is essential to study the relationship between the pore structure

Identifying forest features that increase resiliency of southern‐boundary snowshoe hare populations in Pennsylvania

open access: yesThe Journal of Wildlife Management, EarlyView.
Snowshoe hare population densities in Pennsylvania were greatest in early‐successional forest and densely‐understoried mature forest. Forest management that increases and maintains the amount of early‐successional forest, or that increases understory complexity in mature forest, would benefit snowshoe hares and may mitigate population declines under ...

Resident and translocated American black bear movement patterns help identify locations for crossing structures along Interstate 40 in Tennessee and North Carolina

open access: yesThe Journal of Wildlife Management, EarlyView.
Bears selected areas with lower percent slope and higher percent canopy, but movement flow across the landscape was more generalized for translocated bears. Interstate 40 was a barrier to movement, but our models predicted several consistent road segments as having higher than average flow where bears might benefit from crossing structures.

The Habitats of European Oak (Quercus) in Poland and General Oak Wood Color Issues

open access: yes
Oak wood color plays a critical role in veneer production, where visual consistency directly affects material value. However, production choices are still often based on experience rather than systematic scientific data.

Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

Tension Wood Formation Following Release of Upland Oak Advance Reproduction [PDF]

open access: yes, 2007
Stem straightening and tension wood formation in advance red oak and white oak reproduction were studied. Saplings straightened either as a result of a lateral branch assuming dominance or by a reorientation of the leaning stem.

Navigating Guaiacyl and Syringyl Lignin Structural Complexity in Intact Plant Cell Walls Through 13C Chemical Shift Mapping by Two‐Dimensional Solid‐State NMR

open access: yesMagnetic Resonance in Chemistry, EarlyView.
We establish a two‐dimensional solid‐state NMR 13C chemical shift mapping framework that resolves diagnostic features and explicitly visualizes spectral overlap among guaiacyl and syringyl lignin substructures in intact plant cell walls. Application across Arabidopsis genotypes and developmental stages, hardwoods, and softwood reveals distinct lignin ...

Do good neighbours compensate for bad climate? The case of sessile oak Quercus petraea in phylogenetically distant neighbourhoods

open access: yesOikos, EarlyView.
Stressful climates threaten the performance of individuals and the survival of species, but individual performance also depends on biotic interactions with neighbours, so that ‘good' neighbours might in theory compensate for ‘bad' climates. However, what makes a good neighbour, and why, has been little studied.
