Biochemical and systematic study of the genus Betula L.

open access: yesActa Societatis Botanicorum Poloniae, 2014
The division of the genus Betula L. accomplished on the basis of the flavonoid composition characteristic for the particular species; the proposed systematic classification also takes the chromosome number and geographical distribution into account.

A novel method based on high‐resolution imaging spectroscopy to predict fine‐root traits and the economics space of fresh tree roots

open access: yesNew Phytologist, EarlyView.
Maps of the estimated root nitrogen concentration in the < 0.5‐mm‐diameter classes of 20 woody species based on the imaging spectroscopy using the shortwave infrared spectral region. Summary Tree fine‐root morphological, anatomical, and chemical traits are important to reflect belowground resource acquisition strategies to support tree growth, but ...

Species‐level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees

open access: yesNew Phytologist, EarlyView.
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to

The tree‐parasitic fungus Cryphonectria carpinicola discovered on European chestnut and European hornbeam in Azerbaijan

open access: yesEPPO Bulletin, Volume 56, Issue 2, Page 370-375, August 2026.
Abstract The ascomycetous fungus Cryphonectria carpinicola is typically found in its asexual form on the European hornbeam, and its sexual state has only recently been discovered in deadwood of different Carpinus species in Japan. Recently, this fungus has been added to the EPPO Alert List due to its increasing incidence in the EPPO region and a ...

The Impact of Climate Change and Human Habitation on Long‐Term Ecological Stability

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 8, August 2026.
ABSTRACT Aim Direct human impacts and climate change jeopardise the stability of ecological systems. Recent trends are built atop a long history of vegetation change from the Pleistocene deglaciation and Holocene human population expansion. We aimed to model a long‐term measure of ecological stability over the last 20,000 years, a period that includes ...

Research on the Mechanism of Natural Products Acting on Chronic Obstructive Pulmonary Disease

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
This figure illustrates that approximately 80 natural compounds exert therapeutic effects against chronic obstructive pulmonary disease by targeting pathological mechanisms such as airway inflammation, oxidative stress, airway remodeling, mucus hypersecretion, emphysema, protease–antiprotease imbalance, apoptosis, and autophagy.
