Assessment of Human Thermal Stress Dynamics and Regional Drivers Across the Arabian Peninsula During 1990–2022 From Observations

International Journal of Climatology, EarlyView.
The results reveal that thermal stress varies substantially across the four AP regions, with winter cold stress in Region I, year‐round heat stress in Region II, pronounced summer heat stress in Region III, and persistent strong to very strong heat stress from late spring to early autumn in Region IV.

Distribution of grasses along an altitudinal gradient in a Venezuelan paramo Distribución de gramíneas a lo largo de un gradiente altitudinal en un páramo de Venezuela

Revista Chilena de Historia Natural, 2004
In Venezuelan paramos grasses, after Asteraceae, are the second family in numerical importance. We studied their distribution in an altitudinal gradient located in Venezuela, Sierra de La Culata, between 2,500 and 4,200 m of altitude.

How Thunderstorms Are Changing in Mexico: Trends and Characteristics

International Journal of Climatology, EarlyView.
Thunderstorm days in Mexico have increased significantly since 1992, with pronounced regional and seasonal contrasts. Increasing moisture emerges as the most spatially coherent environmental signal. At the same time, enhanced instability characterizes northeastern and central Mexico, revealing distinct regional controls on thunderstorm activity and ...

Temperature Sensitivity of the Humus Form Tangel

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Tangel is an important humus form in mountain forests, particularly in areas of carbonate rock. To gain an initial understanding of its sensitivity to rising temperatures, a respiration experiment was conducted. The derived Q10 values (3.35–3.36) are comparatively high in relation to values reported in the literature, indicating that Tangel is

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.

A talus rock glacier in Nantlle Valley, North Wales

Journal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

Journal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...
