Guilhem Maurice Louis Banc-Prandi, Sanjeev Kumar, Michele Saba
Novel species of fungi described in this study include those from various countries as follows: Australia, Aschersonia mackerrasiae on whitefly, Cladosporium corticola on bark of Melaleuca quinquenervia, Penicillium nudgee from soil under Melaleuca quinque ...
Leiden2023Experimental 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 ...
2020Ecological 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 ...
EPFL2017Responses of antinomic foliar traits to experimental climate forcing in beech and spruce saplings
Alexandre Buttler, Rodolphe Schlaepfer, 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 ...
Pergamon-Elsevier Science Ltd2017Disturbance-grazer-vegetation interactions maintain habitat diversity in mountain pasture-woodlands
Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer
Low-intensity livestock grazing is a widespread management tool in order to maintain habitat diversity in mountain pasture-woodlands for nature conservation purposes. Historical photographs indicate that forest disturbance significantly contributed to fore ...
Elsevier Science Bv2017Spruce 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 ...
Bogucki Wydawnictwo Naukowe2017Multi-scale feedbacks between tree regeneration traits and herbivore behavior explain the structure of pasture-woodland mosaics
Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer
The pasture-woodlands of Central Europe are low-intensity grazing systems in which the structural richness of dynamic forest-grassland mosaics is causal for their high biodiversity. Distinct mosaic patterns in Picea abies- and Fagus sylvatica-dominated pas ...
Springer Verlag2016Linear friction welding of spruce boards: experimental investigations on scale effects due to humidity evaporation
Yves Weinand, Bernhard Stamm, 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 ...
Springer2014Loss of tensile strength in cellulose tissue on the surface of spruce (Picea abies) caused by natural photodegradation and delignification
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 ...
Elsevier2013Modern pollen rain and fungal spore assemblages from pasture woodlands around Lake Saint-Point (France)
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 ...
