C. C. Uhlenbeck on Indo-European, Uralic and Caucasian [PDF]

open access: yes, 2010
In his early years, C. C. Uhlenbeck was particularly interested in the problem of the Indo-European homeland (1895, 1897). He rejected Herman Hirt’s theory (1892) that the words for ‘birch’, ‘willow’, ‘spruce’, ‘oak’, ‘beech’ and ‘eel’ point to Lithuania

The interplay between hydraulic capacitance and stomatal regulation strategy affects soil–plant hydraulics and transpiration

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2988-3000, June 2026.
Summary Plant water storage contributes to transpiration, but it is unclear how its relevance in supporting transpiration depends on the stringency of stomatal regulation. Here, we show the compounding effect of stomatal regulation and hydraulic capacitance on plant water use, by means of a soil–plant hydraulic model and measurements of leaf water ...

Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees

open access: yesPlant, Cell &Environment, Volume 49, Issue 6, Page 3351-3362, June 2026.
ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with

Factors determining the occurrence of Flat Bugs (Aradidae) in beech dominated forests [PDF]

open access: yes, 2007
The habitat requirements of most Aradidae and the decisive factors that influence their occurrence are still poorly understood. To reduce this lack of knowledge a standardised survey of Aradidae in two large beech forest areas of Bavaria (northern ...

Quantifying the Rapid Propagation of Rainfall and Evapotranspiration Signals Into Soils

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Precipitation and evapotranspiration are major drivers of soil moisture dynamics, which in turn influence plant water availability, biogeochemical reactions, and trace gas emissions. However, it has been unclear whether evapotranspiration signals propagate through soil columns differently than precipitation signals do.

The assessment of naturalness and its role for nature conservation and forestry in Europe [PDF]

open access: yes, 2008
Naturalness is one of the most important criteria in nature conservation. This paper examines the fundamental concepts underlying the definition and assessment of naturalness.

An Ecological Dipole in North American Mast‐Eating Small Mammal Dynamics

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Ecological dipoles are patterns in plant and animal indices of opposite extremes, and many ecological dipoles may exist. We discovered a novel ecological dipole in seed‐eating small mammals in North America using spatial analyses. We also tested for associations between climate variables and small mammal synchrony, and found that site proximity as well

Assessments of Impacts of Nitrogen Deposition on Beech Forests: Results from the Pan-European Intensive Monitoring Programme

open access: yesThe Scientific World Journal, 2001
The article reviews effects of nitrogen (N) deposition on beech forest ecosystems in Europe. On the basis of beech plots of the Pan-European Monitoring Programme of ICP Forests and the EU, the deposition of N compounds as well as input-output budgets are

Influence of Deadwood, Tree‐Related Microhabitats, and Forest Structural Features on Saproxylic Arthropod Diversity

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We used environmental DNA (eDNA) metabarcoding across 135 temperate forest plots in Germany to examine how deadwood, tree‐related microhabitats (TreMs), and forest structure shape saproxylic arthropod communities. Structural equation modeling revealed that TreM richness and deadwood volume are key predictors of arthropod diversity, highlighting the ...

Characterization of the Wild Trees and Shrubs in the Fergana Valley: Diversity and Distribution, Threats

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The content of this paper is significant because it presents the first comprehensive assessment of the dendroflora of the Fergana Valley, contributes to understanding species richness across biogeographic regions, and places the results in the context of Central Asian flora and global biodiversity studies.
