Regeneration in gap models: priority issues for studying forest responses to climate change [PDF]

open access: yes, 2001
Recruitment algorithms in forest gap models are examined with particular regard to their suitability for simulating forest ecosystem responses to a changing climate. The traditional formulation of recruitment is found limiting in three areas.

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

open access: yesNew Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Applying Geospatial Semantic Array Programming for a Reproducible Set of Bioclimatic Indices in Europe

open access: yes, 2014
Bioclimate-driven regression analysis is a widely used approach for modelling ecological niches and zonation. Although the bioclimatic complexity of the European continent is high, a particular combination of 12 climatic and topographic covariates was ...

Influence of Tree Species on Frequency of Trap-Nest Use by \u3ci\u3ePassaloecus\u3c/i\u3e Species (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
Habitat selection by Passaloecus spp. based upon tree species used as stations for artificial nesting sites were studied. Data suggest that Passaloecus areolatus preferred Juglans and that P.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

‘Why Did You Go to Buda?’: The Humanist Sodality and Mantuan’s Rustic Idyll in Bohuslaus of Hassenstein’s Ecloga sive Idyllion Budae (1503)☆

open access: yesRenaissance Studies, EarlyView.
Abstract In the late fifteenth century, the Hungarian royal court at Buda was home to a cosmopolitan community of humanists. In early modern historiography, this cultural milieu has often been interpreted as one of the new, emergent ‘centres’ of the Renaissance in East Central Europe.

Does the climate of the origin control anatomical characteristics of the vessel elements as well as different foliar traits in Fagus crenata?

open access: yesJournal of Forest Science, 2011
The relationships between climatic factors and anatomical characteristics of the vessel elements as well as different foliar traits were investigated in Fagus crenata seedlings originating from different provenances.

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,

X-ray tomography as a tool for detailed anatomical analysis [PDF]

open access: yes, 2009
Wood identification, anatomical examination and retrieval of quantitative information arc important aspects of many research disciplines. Conventional light microscopy with a camera and (semi)automatic image analysis software is an often used methodology
