Duftstoffe aus Holzalterungsprozessen als Infochemikalien für Trypodendron domesticum L. (Col., Scolytidae) und dessen Bedeutung innerhalb der Buchenkomplexkrankheit [PDF]

open access: yes, 2008
Beginning in Belgium 1999, low mountain ranges of middle Europe were afflicted with the “European beech bark disease” (EBBD). It was first described by Hartig in 1878 as a complex disease where infestation of beech scale (Cryptococcus fagisuga; Hemiptera,

A first assessment of genetic variability in the longhorn beetle Rosalia alpina (Coleoptera: Cerambycidae) from the Italian Apennines [PDF]

open access: yes, 2018
The Rosalia longicorn (Rosalia alpina) is a strictly protected saproxylic beetle, widely distributed in Central and Southern Europe and mainly associated with ancient beech forests. To improve knowledge about the conservation status of R. alpina in Italy,

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Cretaceous and Paleogene Fagaceae from North America and Greenland: evidence for a Late Cretaceous split between Fagus and the remaining Fagaceae

open access: yesActa Palaeobotanica, 2016
Modern lineages of the beech family, Fagaceae, one of the most important north-temperate families of woody flowering plants, have been traced back to the early Eocene.

A Mariotte-based verification system for heat-based sap flow sensors [PDF]

open access: yes, 2012
Determination of the accuracy of commonly used techniques for measuring sap flux density in trees often presents a challenge. We therefore designed and built a verification system for heat-based sap flow sensors typically used at stem level.

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Longevity in plants impacts phylogenetic and population dynamics

open access: yesNew Phytologist, EarlyView.
Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.

MICROPROPAGATION OF Fagus spp.

open access: yes, 2003
619 pp. The genus Fagus, a member of the Fagaceae family, comprises ten species of monrecious trees native to the Northern Hemisphere Temperate Zone regions of Eurasia and Eastern North America. The name Fagus (related to Greek phagein, to eat) is a reference to the distinctive triangular nuts of these species, which are eaten by ...
