The watering of tall trees - Embolization and recovery [PDF]

, 2015
We can propound a thermo-mechanical understanding of the ascent of sap to the top of tall trees thanks to a comparison between experiments associated with the cohesion-tension theory and the disjoining pressure concept for liquid thin-films.

Modeling Sub‐Grid Peatland Vegetation Dynamics in the ORCHIDEE‐PEAT Land Surface Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Peatlands store about one‐third of total global soil carbon. Vegetation composition strongly regulates peatland carbon dynamics. Global warming and climate‐driven ecohydrological changes are expected to alter peatland vegetation composition, necessitating accurate simulation of vegetation dynamics to predict future fate of peatland carbon.

Effects of habitat quality and fine‐scale spatial structure on epiphytic lichen and bryophyte communities

Journal of Ecology, Volume 114, Issue 3, March 2026.
Host‐tree identity, particularly bark physico‐chemical traits, emerged as the dominant driver of epiphytic lichen and bryophyte community composition in this closed‐canopy temperate forest system, while microclimate plays a subordinate role. Spatial structure and proximity contributed additional effects for both groups, but for lichens, habitat ...

Radial Distribution of Lipophilic Extractives in Walikukun (Schoutenia ovata Korth.) Wood

South-East European Forestry
Walikukun (Schoutenia ovata Korth.) is a commercially significant wood species in Indonesia. Heartwood, in particular, is important due to the natural durability and aesthetics, while lipophilic extractives play a crucial role in the formation. Therefore,

A Tell-Tale Heartwood [PDF]

Microscopy Today, 1999
Abstract In Medieval Europe, manuscripts and formulas on the preparation of colors and dyes used by chemists and artists contained many references to natural plant extracts, The yellow stigmas of aromatic saffron (Crocus sativus) were crushed and used both as a medicine and colorant as far back as the ninth century BCE.

A specific case in the classification of woods by FTIR and chemometric: discrimination of Fagales from Malpighiales [PDF]

, 2014
Fourier transform infrared (FTIR) spectroscopic data was used to classify wood samples from nine species within the Fagales and Malpighiales using a range of multivariate statistical methods. Taxonomic classification of the family Fagaceae and Betulaceae
