Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

Water Filtration Using Plant Xylem [PDF]

, 2013
Effective point-of-use devices for providing safe drinking water are urgently needed to reduce the global burden of waterborne disease. Here we show that plant xylem from the sapwood of coniferous trees – a readily available, inexpensive, biodegradable ...

Discovery of murayaquinone from an endophytic bacterium Streptomyces sp. AN140557 as a potent inhibitor of the pine wood nematode, Bursaphelenchus xylophilus

Pest Management Science, Volume 82, Issue 2, Page 1765-1775, February 2026.
Murayaquinone isolated from the pine endophyte Streptomyces sp. AN140557 exhibits potent, dose‐dependent nematicidal activity and egg‐hatching inhibition against the pine wood nematode. It effectively inhibited pine wilt disease in greenhouse tests, suggesting potential as a promising biocontrol agent.

Transitional Pitting in Tracheids of Psilotum

Annals of the Missouri Botanical Garden, 1936
Most of the anatomical studies upon Psilotum have been in connection with the interpretation of the spore-bearing structures and with the general organization of the stele. Accounts of the anatomical organization of the axis have been largely topographical, discussing the distribution of the cortical tissues and the differentiation of the stelar ...

Automatic identification of cell files in light microscopic images of conifer wood [PDF]

, 2010
International audienceIn this paper, we present an automatic method to recognize cell files in light microscopic images of conifer wood. This original method is decomposed into three steps: the segmentation step which extracts some anatomical structures ...

From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees

Biological Reviews, Volume 101, Issue 1, Page 314-335, February 2026.
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...

Anomalous roughening of wood fractured surfaces

, 1998
Scaling properties of wood fractured surfaces are obtained from samples of three different sizes. Two different woods are studied: Norway spruce and Maritime pine. Fracture surfaces are shown to display an anomalous dynamic scaling of the crack roughness.

Tree defenses, host choice, and reproductive success of a native bark beetle under novel outbreak conditions

Ecological Applications, Volume 36, Issue 1, January 2026.
Abstract Bark beetles of the genus Dendroctonus are some of the most important disturbance agents in North American forests, having colonized conifers for millions of years. The selection pressure posed by tree‐killing bark beetles pushed trees to develop an arsenal of defensive strategies to which beetles have adapted in their turn.

Impact of drought on Eucalyptus wood chemistry by near infra red hyperspectral imaging [PDF]

, 2019
The aim is to study tree development submitted to different water and mineral constraints. The objective is to correlate spatial distribution of wood chemistry with wood density secondary growth.

Vertical Stratification Drives Divergent Spatial Trade‐Offs Among Xylem Cell Types in Angiosperm Trees of a Mountain Forest in Eastern China

Ecology and Evolution, Volume 16, Issue 1, January 2026.
To understand how vertical forest stratification influences xylem functional balance, we measured vessel, fiber, and parenchyma fractions across 39 tree species in eastern China. Key trade‐offs exist between vessel‐fiber and parenchyma‐fiber fractions.
