On the Temporal Variability of Precipitation in Iraq: Arid‐Wet Years and Extreme Events
International Journal of Climatology, EarlyView.Daily and monthly precipitation data in Iraq display high seasonal to interdecadal variability, with arid and wet years that have very distinct seasonal cycles. Monthly rainfall is significantly correlated with the Indian Ocean Dipole. Extreme events are identified and classified as belonging to four different weather patterns, allowing to obtain daily

Journal of Quaternary Science, EarlyView.ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Adaptation of sheep breedings systems to changes in the Allgerian steppe context - Case of the region of M'Msila [PDF]
, 2019 The Algerian steppe extends over an area of 20 million hectares (rainfall between 100 and 400 mm/year). It supports a grazed ecosystem whose balance had been found by local populations, in particular through movements of animals (Achaba and Azzaba).

Astragalus ecomorphology in Quaternary elephantids
Journal of Quaternary Science, EarlyView.ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...
