Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

Journal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Carbon, Nitrogen, and Corresponding Stable Isotope Signatures Reveal Channel Banks as Major Sediment Sources in a Tropical Agricultural Watershed

Land Degradation &Development, EarlyView.
ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

EEG Dynamics in Children Before, During and After General Anesthesia

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Age‐specific EEG signatures during anesthesia are described in pediatrics, and perioperative monitoring is increasingly advocated; yet most indices and algorithms derive from adult data and may not generalize to early development. Aims The purpose of this study was to characterize perioperative frontal EEGs in young children younger

Cryomagma ascent on Europa [PDF]

, 2019
Europa's surface exhibits morphological features which, associated with a low crater density, might be interpreted to have formed as a result of recent cryovolcanic activity. In particular, the morphology of smooth deposits covering parts of the surface,

Lernaufgabe Europa

Hessische Blätter für Volksbildung, 2013
Ein gemeinsamer Wirtschaftsraum schafft keine gesellschaftliche Einheit. Von gewachsenen Verbindungen und Wahlverwandtschaften kann im europäischen Kontext kaum die Rede sein. Nach dem Zerbrechen des Abendlandes war Frieden in Europa eher beschränkt auf seltene Zeiträume.

Unveiling human–wildlife interactions in the context of livestock grazing abandonment and the return of large carnivores, ungulates and vultures: A stakeholder perspective

People and Nature, EarlyView.
Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.
