Control of invasive conifers in temperate Andean forests promotes native vegetation restoration, but requires continuous management

Trees, Forests and People
Non-native conifers have been planted widely because of their growth potential and wood quality. However, many of them have become invasive in the introduced ranges.

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

COMPARISON OF FAILURE CRITERIA FOR WOOD IN TENSILE-SHEAR STRESS STATE

Acta Polytechnica CTU Proceedings, 2017
An orthotropic failure criterion enhancing the Lourenco's criterion by a shear strength multiplier and a maximum shear strength upper bound has been recently proposed and validated for timber under tensile and shear loading by the authors.

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

Entomologia Experimentalis et Applicata, EarlyView.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

Journal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Mapping Species at an Individual-Tree Scale in a Temperate Forest, Using Sentinel-2 Images, Airborne Laser Scanning Data, and Random Forest Classification

Remote Sensing, 2020
Detailed information about tree species composition is critical to forest managers and ecologists. In this study, we used Sentinel-2 imagery in combination with a canopy height model (CHM) derived from airborne laser scanning (ALS) to map individual tree

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

From pathogens to partners: temporal and biogeographical patterns in fungal associations of alien trees

New Phytologist, EarlyView.
Summary Alien trees reshape belowground fungal communities, but the factors governing the balance between mutualists and pathogens remain unclear. We tested whether residence time, mycorrhizal type, and biogeographical origin shape this balance, and whether alien stands differ from native vegetation. We sampled soils beneath 73 alien tree species in 48
