Divergent functions of three Kunitz trypsin inhibitor (KTI) proteins in herbivore defense in poplar

open access: yesBMC Plant Biology
Background Climate warming promotes the expansion of insect pests. Among the inducible defense responses activated by attacked plants, Kunitz trypsin protease inhibitors (KTIs) play an outstanding role.

Effects of post-fire logging on forest surface air temperatures in the Siskiyou Mountains, Oregon, USA [PDF]

open access: yes, 2010
Following stand-replacing wildfire, post-fire (salvage) logging of fire-killed trees is a widely implemented management practice in many forest types. A common hypothesis is that removal of fire-killed trees increases surface temperatures due to loss of ...

Unveiling the Role of Curvature in Carbon for Improved Energy Release of Ammonium Perchlorate

open access: yesAdvanced Materials, EarlyView.
High‐curvature carbon materials identified via machine learning and simulation can enhance the heat release and combustion performance of ammonium perchlorate. ABSTRACT The catalytic role of carbon curvature in the thermal decomposition of ammonium perchlorate (AP) remains largely unexplored. To address this gap, this study employs machine learning and

The relationship among stress-wave-based wood stiffness and growth traits revealed by planting density trial with multiple genotypes in Cryptomeria japonica

open access: yesJournal of Wood Science
Understanding the genetic and environmental factors influencing wood stiffness is essential for improving wood quality in plantation forestry. In this study, we investigated the phenotypic, genetic, and environmental variation in wood stiffness, measured

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

open access: yesAdvanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Transcriptional time-course analysis during ash dieback infection revealed different responses in tolerant and susceptible Fraxinus excelsior genotypes

open access: yesBMC Plant Biology
Hymenoscyphus fraxineus, the causal agent of Ash Dieback (ADB), has been introduced to eastern Europe in the 1990s from where it spread causing decline in European ash populations.

ENVIRONMENTAL VARIABLES ASSOCIATED WITH INVASIVE GLOSSY BUCKTHORN (FRANGULA ALNUS MILL.) AND INDIRECT CONTROL STRATEGIES FOR FOREST MANAGERS [PDF]

open access: yes, 2016
Glossy buckthorn (Frangula alnus Mill.) is one of the most prominent non-native invasive plant species affecting New England forests. It quickly invades a forest and can create a dense understory effectively altering the species composition and dynamics

Linkages between Phosphorus and Plant Diversity in Central European Forest Ecosystems—Complementarity or Competition? [PDF]

open access: yes, 2019
The phosphorus nutrition status of European forests has decreased significantly in recent decades. For a deeper understanding of complementarity and competition in terms of P acquisition in temperate forests, we have analyzed α-diversity, organic layer ...
