Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, Volume 55, Issue 4, Page 612-628, July/August 2026.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Spatial behavior of socially isolated wild pigs (Sus scrofa) following sounder removal via trapping

Pest Management Science, Volume 82, Issue 6, Page 5225-5236, June 2026.
Following partial sounder removal, socially isolated wild pigs maintained site fidelity near traps, highlighting post‐control behavioral tendencies that are relevant to pest management and disease mitigation. Abstract BACKGROUND The rapid expansion of wild pig (Sus scrofa) populations across North America, coupled with increased concern over disease ...

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

New Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

SURVIVAL TIME AND EFFECTIVENESS OF GIRDLING AND HERBICIDE METHODS IN THE CONTROL OF Pinus elliotti: A CASE STUDY IN SECONDARY ATLANTIC FOREST IN SOUTHEASTERN BRAZIL

Revista do Instituto Florestal
Pinus elliottii is a notorious invasive exotic species in grassland ecosystems; however, it can also establish itself in forest ecosystems during secondary succession. In this case, killing invasive standing trees is preferable to cutting, as it reduces

Genetic parameters and selection indices for a population of Pinus elliottii Engelm. var. elliottii

, 1993
P. elliottii Engelm. var. elliottii is an important exotic plantation species in Zimbabwe, where it is grown for saw-timber and resin production. Three progeny tests, originating from factorial matings between parents selected in plantations, were assessed at five, eight and 15 years.
