Survey of Subterranean Termite (Isoptera: Rhinotermitidae) Utilization of Temperate Forests

open access: yesSociobiology, 2014
Both native and invasive subterranean termites (Isoptera: Rhinotermitidae), including the Formosan subterranean termite, are well known pests of urban areas, but little is known about their distribution or impact in forest ecosystems of the southeastern ...

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

open access: yesAngewandte Chemie International Edition, EarlyView.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...

A Quantitative Approach for Assessing and Monitoring the Social Licence of Forestry to Operate: A New Zealand Case Study

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Social Licence to Operate (SLO) is an increasingly strategic concern in forestry, yet its evaluation remains largely qualitative. This study presents the first quantitative framework for assessing SLO in New Zealand's forestry sector, adapted from the Boutilier and Thomson model, originally developed for the mining sector.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

open access: yesFire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting

open access: yesMacromolecular Rapid Communications, EarlyView.
Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.
