Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

Journal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

Review of the Salpausselkä ice‐marginal formations in Finland

Journal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...

Climate‐modulated accumulation and erosion of sediments in the Rodderberg crater basin for the last 439 ka (East Eifel Volcanic Field, Germany)

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial/interglacial climate cycles since marine isotope stage (MIS) 12 influenced the discontinuous and 73 m‐long sediment record from the volcanic crater of Rodderberg in the East Eifel Volcanic Field, Germany. High‐resolution grain size and geochemical data have been valued by numerical dating techniques (radiocarbon and luminescence dating,

The Carbonate Raman Processing and Plotting Tool: A Software Application for 2‐Dimensional Raman Image Peak‐Fitting and Visualization

Journal of Raman Spectroscopy, EarlyView.
We present the Carbonate Raman Processing and Plotting tool (CaRPP), designed to perform peak‐fitting and visualization on two‐dimensional Raman maps of calcium carbonate specimens. Users begin by providing a raw Raman data file and then interactively use the application to perform peak‐fitting, masking, and 2‐D image generation.

Evolution of Pigments in Artificially Aged Polyethylene Plastics: A Raman Study

Journal of Raman Spectroscopy, EarlyView.
The evolution of specific pigments included in plastics exposed to UVA is studied using Raman spectroscopy. This approach is applicable to both organic and inorganic pigments and is facilitated by resonance mechanisms. ABSTRACT The degradation mechanisms of polymers under UV exposure and the evolution of additives are a major concern due to their ...

Setting the Record Straight: The Intellectual Legacy of H. Igor Ansoff (1918–2002)

Strategic Change, EarlyView.
ABSTRACT This study presents a comprehensive annotated bibliography of H. Igor Ansoff's intellectual contributions, addressing significant gaps in existing citation databases such as Scopus and Web of Science, which capture only 9 to 15 percent of his work.

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.

Modeling effects of environmental conditions and hunter activity on Montezuma quail harvest in Arizona

The Journal of Wildlife Management, EarlyView.
Models of spatiotemporal variation in hunter harvest show that monsoon precipitation and changes in hunter behavior and composition are the primary drivers underlying variation in annual harvest of Montezuma quail. The demographic structure of the previous year's harvest was also strongly associated with the magnitude and rate of annual harvest ...
