Wood nutrients: Underexplored traits with functional and biogeochemical consequences

open access: yesNew Phytologist, Volume 244, Issue 5, Page 1694-1708, December 2024.
Summary Resource storage is a critical component of plant life history. While the storage of nonstructural carbohydrates in wood has been studied extensively, the multiple functions of mineral nutrient storage have received much less attention. Here, we highlight the size of wood nutrient pools, a primary determinant of whole‐plant nutrient use ...

Breeding and seed production aspects of conservation and reproduction of Austrian stone pine (Pinus cembra L.) populations in the Ukrainian Carpathians

open access: yesНаукові праці Лісівничої академії наук України, 2019
The results of forestry and selection studies of Alpine stone pine (Pinus cembra L.) are presented in four test plots of 0.6 to 1.0 ha, planted in stands with its predominance at hypsometric levels of 1150-1380 m above sea level in Gorgany.

Bark structure is coordinated with xylem hydraulic properties in branches of five Cupressaceae species

open access: yesPlant, Cell &Environment, Volume 47, Issue 5, Page 1439-1451, May 2024.
Abstract The properties of bark and xylem contribute to tree growth and survival under drought and other types of stress conditions. However, little is known about the functional coordination of the xylem and bark despite the influence of selection on both structures in response to drought.

Functional traits of fossil plants

open access: yesNew Phytologist, Volume 242, Issue 2, Page 392-423, April 2024.
Summary A minuscule fraction of the Earth's paleobiological diversity is preserved in the geological record as fossils. What plant remnants have withstood taphonomic filtering, fragmentation, and alteration in their journey to become part of the fossil record provide unique information on how plants functioned in paleo‐ecosystems through their traits ...

Biomass distribution of different-aged needles in young and old Pinus cembra trees at highland and lowland sites [PDF]

open access: yes, 2018
Conifer needles of different ages perform differently in ecophysiology. However, no study has investigated the biomass distribution of different-aged needles in a tree crown or/and a stand canopy. We carried out a study on young (∼50 years old) and old (∼
