Reduced Sulfur Availability has an Impact on N‐Nutrition of Norway Spruce (Picea abies) and European Beech (Fagus sylvatica)

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Calculating regressions between main foliar nutrient elements from German forest survey data reveals a relationship between S and N for beech, spruce, pine, and oak. For beech and spruce this relationship can be interpreted as a limiting effect of S on N, as known in agriculture and compensated there by S‐fertilization. Due to strongly reduced

Intrusive origin of the Sudbury Igneous Complex: Structural and sedimentological evidence [PDF]

open access: yes
In recent years, many geoscientists have come to believe that the Sudbury event was exogenic rather than endogenic. Critical to a recent exogenic hypothesis is the impact melt origin of the Sudbury Igneous Complex (SIC).

Mountainous vegetation succession and land use during the last millennium in the Peloponnese (southern Greece): Environmental change and economic development in an isolated periphery

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Mediterranean mountainous areas and their valuable natural resources have long been attractive to human societies. The Peloponnese (southern Greece), with its complex topographic and climatic variability, has been the scenery for the development of numerous human communities.

Proteomic analysis resulting in species‐level identification of recently diverged North American arvicoline rodents

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT North American arvicoline rodents have long been considered to have high biogeographic, biochronologic, and paleoecological value. They provide relative dating of faunal assemblages when absolute dating is not possible and contribute to paleobiome characterization.

Study of Garnets in Hellenistic–Roman Jewellery From the Collections of the Archaeological Museum of Thessaloniki, Greece

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study presents the gemological analysis of 25 garnets from Hellenistic and Roman jewellery in the Archaeological Museum of Thessaloniki using mobile Raman spectroscopy and micro‐EDXRF. The garnets are classified into three geochemical clusters, with notable differences in distribution between Thessaloniki and Pydna, suggesting distinct trading ...

Evaluation of ERTS-1 imagery for geological sensing over the diverse geological terrains of New York State [PDF]

open access: yes
Film positives of ERTS-1 imagery, both as received from NASA and photographically reprocessed, are analyzed by conventional and color additive viewing methods. The imagery reveals bedrock and surficial geological information at various scales.

Granitoid emplacement during a thrusting event: structural analysis, microstructuel and quartz-c-axis patterns. An example from hercynian plutons in the French Massif Central.

open access: yes, 2004
n the French Massif Central, the Rouergue–Albigeois area consists of three tectonic units stacked during the Hercynian orogeny. The structural analysis of the units and particularly the quartz left angle bracketcright-pointing angle bracket axis ...

Effects of (Assisted) Natural Regeneration on Infiltrability and Preferential Flow Pathways in the Khasi Hills (Meghalaya, NE India)

open access: yesLand Degradation &Development, Volume 36, Issue 5, Page 1564-1578, March 2025.
ABSTRACT Intensified slash‐and‐burn cultivation and forest clearing have caused severe land degradation in the Khasi Hills (Meghalaya plateau, NE India). Despite very high annual rainfall, the region faces severe water scarcity during the dry season.
