Twenty years of irrigation acclimation is driven by denser canopies and not by plasticity in twig- and needle-level hydraulics in a Pinus sylvestris forest

Charlotte Grossiord, Eugénie Isabelle Mas, Christoph Bachofen, Alex Tunas Corzon, Hervé Cochard, Alice Jacqueline Frédérique Gauthey

Climate change is predicted to increase atmospheric vapor pressure deficit, exacerbating soil drought, and thus enhancing tree evaporative demand and mortality. Yet, few studies have addressed the longer-term drought acclimation strategy of trees, particul ...

Plant Terpenes on Treating Cardiovascular and Metabolic Disease: A Review

Rodrigo Araujo Fraga Da Silva

The use of medicinal plants as a therapy alternative is old as human existence itself. Nowadays, the search for effective molecules for chronic diseases treatments has increased. The cardiometabolic disorders still the main cause of death worldwide and pla ...

Experimental investigation of mesoscale variability of clear spruce mechanical properties in the radial direction

Thomas Keller, Anastasios Vassilopoulos, Alireza Farajzadeh Moshtaghin, Steffen Franke

The aim of this work is the investigation of mesoscale/local variability in mechanical properties of clear timber in the radial direction. Clear Norway spruce wood, Picea abies, was used for cutting specimens of different lengths with a small cross-section ...

Joinery Solver for Whole Timber Structures

Yves Weinand, Petras Vestartas

This paper presents a digital joinery generation method for whole-timber structures using wood-wood connections. The research is based on a collaboration with a local timber company located in a mountain area [1]. In this context, there is a need to explor ...

Reconsidering traditional timber joinery for sustainable structures

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting

Timber construction plays an important role in architectural history, in modern construction methods and in sustainable design, for which wood-only joinery techniques have been used for centuries. Traditional joinery typologies are the product of successiv ...

Impacts of regional climatic fluctuations on radial growth of Siberian and Scots pine at Mukhrino mire (central-western Siberia)

Luca Bragazza, Guillaume Blanchet, Baptiste Calliari

Ring width (TRW) chronologies from Siberian (Pinus sibirica) and Scots (Pinus sylvestris) pine trees were sampled at Mukhrino - a large mire complex in central-western Siberia - to evaluate the impacts of hydroclimatic variability on tree growth over the l ...

Ecological response of tree saplings to simulated climate change along an elevational gradient (CLIMARBRE)

María Paula Sanginés De Cárcer

Switzerland will face higher temperature increases than the global average, which will have strong impacts on the mountain ecosystems. How tree species will respond to future climate change scenarios, and what mechanisms will they adopt, remains as a gap o ...

Responses of antinomic foliar traits to experimental climate forcing in beech and spruce saplings

Rodolphe Schlaepfer, Alexandre Buttler, María Paula Sanginés De Cárcer, Constant Signarbieux

Global warming is predicted to have a strong impact on mountain ecosystems. Subalpine sylvopastoral systems are very sensitive to climate change, which puts their future sustainability at stake. These ecosystems are mostly dominated by spruce and beech, an ...

Spruce tree-ring proxy signals during cold and warm periods

The strength and temporal rigidity of climate signals are important characteristics of proxy data used to reconstruct climate variability over pre-instrumental periods. Here, we assess the performance of different tree-ring proxies, including ring width, m ...

Quantification of spatial variability for transverse elastic modulus of spruce wood

Thomas Keller, Anastasios Vassilopoulos, Alireza Farajzadeh Moshtaghin, Steffen Franke

Different factors such as age, location of timber within the tree, structural imperfections, load history such as wind and snow etc. can affect the material properties of timber. Consequently, there is a high variability in the mechanical properties which ...

Placing unprecedented recent fir growth in a European-wide and Holocene-long context

Jed Oliver Kaplan

Forest decline played a pivotal role in motivating Europe's political focus on sustainability around 35 years ago. Silver fir (Abies alba) exhibited a particularly severe dieback in the mid-1970s, but disentangling biotic from abiotic drivers remained chal ...

Biomimetic Synthesis of (+)-Ledene, (+)-Viridiflorol, (-)-Palustrol, (+)-Spathulenol, and Psiguadial A, C, and D via the Platform Terpene (+)-Bicyclogermacrene

Nicolai Cramer, Duc Tran Ngoc

(+)-Bicyclogermacrene is a strained bicyclic and common sesquiterpene found in several essential oils. A short and good yielding synthesis of bicyclogermacrene proceeding in seven steps is reported. This terpene is used as key platform intermediate for a b ...

Analytical modeling of local stresses at Balsa/timber core joints of FRP sandwich structures

Julia De Castro San Roman Fest, Thomas Keller, Anastasios Vassilopoulos, Michael Osei-Antwi

In order to optimize sandwich structures, core materials of different density and thus different stiffness and strength are often combined. The material discontinuities at joints of dissimilar core materials may lead to abrupt changes of the shear angles a ...

CNC-fabricated dovetails for Joints of Prefabricated CLT Components

Yves Weinand, Paul Mayencourt, Benjamin Hahn, Christopher Werner Matthias Robeller

The widely available automated prefabrication in timber construction companies, as well as modern CAD software with application programing interfaces, allow for the design and production of increasingly geometrically complex building components. This devel ...

Linear friction welding of spruce boards: experimental investigations on scale effects due to humidity evaporation

Bernhard Stamm, Yves Weinand, Benjamin Hahn

Recent investigations on friction welded wood-to-wood connections have shown interesting capacities of these adhesive free joints for further development towards constructional elements. This paper addresses challenges and technical requirements for the en ...

Loss of tensile strength in cellulose tissue on the surface of spruce (Picea abies) caused by natural photodegradation and delignification

John Christopher Plummer

Photodegradation of wood leads to discolouration and delignification, inducing damage to the cellular structure. This study is an investigation of the damage and loss of tensile strength of the cellulose fibres in spruce (Picea abies). Microtensile tests i ...

Modern pollen rain and fungal spore assemblages from pasture woodlands around Lake Saint-Point (France)

François Gillet

Modern analogs are commonly used to investigate the relationships between modern pollen rain and the surrounding present vegetation and to improve our interpretation of fossil data. We collected modern pollen and spore rain in 18 more or less grazed and/or ...

Long-term dynamics of aboveground fungal communities in a subalpine Norway spruce forest under elevated nitrogen input

Rita Bütler Sauvain, François Gillet, Simon Egli

As anthropogenic N deposition has been suspected to be the main reason for the decline of macromycetous sporocarp production in forest ecosystems, various N-fertilization experiments were started in the mid 1990s. The dynamics of ectomycorrhizal (root-inha ...

Looking for differences in wood properties as a function of the felling date: lunar phase-correlated variations in the drying behavior of Norway Spruce (Picea abies Karst.) and Sweet Chestnut (Castanea sativa Mill.)

Rodolphe Schlaepfer

A large-scale field experiment on the drying behavior of Norway Spruce (Picea abies Karst.) and Sweet Chestnut (Castanea sativa Mill.) in relation to the felling date was conducted over a period of 24 weeks in order to investigate the existence of variatio ...
