Victims or perpetrators: contribution and response of insects to forest diebacks and declines
By Véronique Lesage On 29 October 2020 In All published articles, Letter to the editor, Open Access, Special issue/Topical collection
Key message Unprecedented forest declines and diebacks are expected worldwide in response to global change. Insects can trigger or contribute to these disturbances, which can in turn have either beneficial or detrimental retroactive cascading effects on insect

Improving aboveground biomass estimates by taking into account density variations between tree components
Key message Strong density differences were observed between stem wood at 1.30 m and other tree components (stem wood, stem bark, knots, branch stumps and branches). The difference, up to 40% depending on the component, should be

On the knowns and unknowns of natural regeneration of silviculturally managed sessile oak (Quercus petraea (Matt.) Liebl.) forests—a literature review
Key message This literature review identified the main factors for the success of different silvicultural approaches to regenerate sessile oak naturally and unveiled at the same time important knowledge gaps. Most previous studies were only short-term and

Defining correct dormancy class matters: morphological and morphophysiological dormancy in Arecaceae
Key message Dormancy in Arecaceae diaspores is due to underdeveloped embryos, therefore, morphological dormancy or morphophysiological dormancy. Consequently, claims such as external seed structures inhibit germination, embryos are fully developed at maturity, and underdeveloped embryo is not

Extended xylogenesis and stem biomass production in Juniperus przewalskii Kom. during extreme late-season climatic events
Key message Late-season extreme climatic events induced variations in wood density and extended growth for more than a month in 2016 in Juniperus przewalskii Kom. growing on the Northeastern Tibetan Plateau, suggesting extraordinary growth resilience of the

Unprecedented pluri-decennial increase in the growing stock of French forests is persistent and dominated by private broadleaved forests
Key message French forests exhibit the fastest relative changes across Europe. Growing stock increases faster than area, and is greatest in low-stocked private broadleaved forests. Past areal increases and current GS levels show positive effects on GS

The utility of fused airborne laser scanning and multispectral data for improved wind damage risk assessment over a managed forest landscape in Finland
Key message The potential of airborne laser scanning (ALS) and multispectral remote sensing data to aid in generating improved wind damage risk maps over large forested areas is demonstrated. This article outlines a framework to generate such

Climate-growth relationships for Aspidosperma tomentosum Mart. in South American tropical dry forests
By Véronique Lesage On 12 October 2020 In All published articles, Data in repository, Research paper, Special issue/Topical collection
Key message The precise demarcation and cross-dating of tree rings in Aspidosperma tomentosum Mart., a valuable timber species in the tropical dry forests of South America, were used to develop the first well-replicated chronology covering the period

Modeling forest site productivity using climate data and topographic imagery in Pinus elliottii plantations of central Argentina
Key message To be useful for silvicultural and forest management practices, the models of Site Index (SI) should be based on accessible predictor variables. In this study, we used spatially explicit data obtained from digital elevation models

Competition overrides climate as trigger of growth decline in a mixed Fagaceae Mediterranean rear-edge forest
Key message In recent decades, there has been a decline in growth in a rear-edge broadleaf forest of Fagus sylvatica, Quercus petraea, and Quercus pyrenaica. Although temperatures have been rising due to climate change, the observed decline
