Properties of dissolved and total organic matter in throughfall, stemflow and forest floor leachate of central European forests [PDF]

Biogeosciences, 2015
We present the first investigation of the composition of dissolved organic matter (DOM) compared to total organic matter (TOM, consisting of DOM, < 0.45 μm and particulate organic matter 0.45 μm < POM < 500 μm) in throughfall, stemflow and forest floor ...

Environmental change impacts on the C- and N-cycle of European forests: a model comparison study [Discussion paper] [PDF]

, 2012
Forests are important components of the greenhouse gas balance of Europe. There is considerable uncertainty about how predicted changes to climate and nitrogen deposition will perturb the carbon and nitrogen cycles of European forests and thereby alter ...

Reduced Phrenic CMAP Amplitudes in Obesity Despite Preserved Diaphragm Ultrasound Measures

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Phrenic nerve conduction studies (NCS) are regularly used in the evaluation of neuromuscular respiratory dysfunction; however, the impact of body mass index (BMI) on phrenic compound muscle action potential (CMAP) amplitudes remains poorly characterized. We evaluated the relationship between BMI and phrenic CMAP amplitudes in

Drivers of wood‐inhabiting fungal diversity in European and Oriental beech forests

Ecology and Evolution
The hyperdiverse wood‐inhabiting fungi play a crucial role in the global carbon cycle, but often are threatened by deadwood removal, particularly in temperate forests dominated by European beech (Fagus sylvatica) and Oriental beech (Fagus orientalis). To

Differential responses of herbivores and herbivory to management in temperate European beech.

PLoS ONE, 2014
Forest management not only affects biodiversity but also might alter ecosystem processes mediated by the organisms, i.e. herbivory the removal of plant biomass by plant-eating insects and other arthropod groups.

Climate sensitivity of silver fir and common beech mixed forests in the Southern Apennines

L'italia forestale e montana, 2014
A recent dendroecological study, carried out on silverfir and beech mixed forests at two sites in Southern Apennines (Italy), showed interesting differential species-specific responses to climate. In particular, a strong influence on tree radial growth was exerted by the precipitation: summer drought stress was the main limiting factor for  both ...

Organic matter and nitrogen dynamics in a mature forest of common beech in the Sierra de la Demanda, Spain [PDF]

Annals of Forest Science, 2001
Aboveground biomass, litterfall, leaf weight loss due to decomposition, N return and seasonal leaf N dynamics were studied in the Sierra de la Demanda, Spain, a Mediterranean climatic zone. The forest ecosystem considered was a climax beech (Fagus sylvatica L.) forest.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Current state of beech bark necrotic disease in Southern Poland

Journal of Forest Science, 2008
The degree of the beech bark necrotic disease was evaluated in three selected localities in southern Poland, in different orographic complexes, Beskid Sądecki, Beskid Niski, and Bieszczady.

Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior

Polymer Composites, EarlyView.
Lichen residue, a renewable mineral‐organic material, was melt compounded with polylactic acid and triacetin in a twin‐screw extruder. ABSTRACT A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA).
