Journal ArticleDOI
Engineered wettability in tree capillaries.
TL;DR: It is demonstrated that nature is able to overcome this deficiency by engineering the roughness of the capillary walls to achieve near complete wetting, a strategy analogous to that used in the natural engineering of the wettability of plant leaves and insect wings.

Intervascular pit membranes with a torus in the wood of Ulmus (Ulmaceae) and related genera
TL;DR: The authors' observations suggest that tori are more common in cold temperate climates than in warm (sub)tropical environments, and may indicate that narrow tracheary elements with torus-bearing pit membranes provide an auxiliary conducting system which is of low conductivity, but offers greater resistance to freezing-induced cavitation.
Journal ArticleDOI
The antiquity of the Rhine River: stratigraphic coverage of the dinotheriensande (eppelsheim formation) of the Mainz Basin (Germany).
TL;DR: This study documents complex faunal mixing of classical Dinotheriensand fauna, covering at least six million years, during a time of low subsidence in the Mainz Basin and shifts back the origination of the Rhine River by some five million years.
Journal ArticleDOI
Early Paleogene climate at mid latitude in South America: Mineralogical and paleobotanical proxies from continental sequences in Golfo San Jorge basin (Patagonia, Argentina)
TL;DR: In this paper, three clay mineral assemblages were identified: Sectite (smectite) dominates the Penas Coloradas Formation, S2 assemblage (sectitegt;kaolinite) occurs in the stratigraphic transition to the Las Flores Formation, and S3 assemblaging (kaolitegt,smectitite) dominated the Las-Flores Formation.

Using the CODIT model to explain secondary metabolites of xylem in defence systems of temperate trees against decay fungi
Hugh Morris,Ari M. Hietala,Steven Jansen,Javier Ribera,Sabine Rosner,Khalifah A. Salmeia,Francis W. M. R. Schwarze +6 more
TL;DR: The CODIT model is used to explain defence processes at the cellular level and proposes the development of a new defence system that is modular-based and incorporates all components (and organs) of the tree from micro-to-macro scales.

Vertical resin ducts in the secondary wood of the abietineae
TL;DR: Character of the tissue associated with the ducts and its interpretation and distribution at wounds andPhylogenetic interpretations and fossil evidence are presented.
Outdoor wood weathering and protection.
TL;DR: The natural weathering process causes exposed wood to discolour and degrade through the effect of light, moisture and staining micro-organisms as mentioned in this paper, but since light does not penetrate wood deeper than 200 mm, degradations reactions are a surface phenomenon.
