ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Soil organic carbon (SOC) and soil inorganic carbon (SIC) are two key components of soil total carbon (STC) pools. However, most studies have focused excessively on SOC, while research on SIC remains limited, especially with regard to different pools of ...

Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

The Dinaric Mountains are a mountain range stretching NW–SE from the Alps to the Albanides–Hellenides in central Europe. The highest parts were occupied by small ice fields and/or valley glaciers during the Quaternary cold periods, while even today some small glaciers still exist in topoclimatically favourable areas.

Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Protected areas on international borders show uneven conservation outcomes
Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...
