Pioneering Evidence of the Dynamics of Water Vapor and CO2 Fluxes in Sahara Desert Soils
Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.Abstract Soil CO2 flux (Fc) is a major component of the global carbon balance. It is often overlooked in arid regions as low soil moisture restricts microbial and root respiration. Studies in the last decades challenge this paradigm, reporting an anomalous diurnal cycle of Fc in arid regions. This diurnal cycle is thought to be initiated by geochemical

Vegetated dunes and barchan dune fields
, 2007 Desertifikation steht in enger Beziehung zu aeolischem Sedimenttransport, einschliesslich der Bildung, Evolution und Bewegung von Sanddünen. Sandduenen bewegen sich in riesigen Clustern von tausenden von Dünen unter einer komplexen internen Dynamik, welche ihre Größe und räumliche Verteilung bestimmt.

Slowdown of Dune Migration in East Asia's Inland Deserts: A 35‐Year Response to Wind Stilling
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract Global terrestrial stilling, the recent decrease in near‐surface wind speeds, has significant environmental impacts, including reduced dust storms and vegetation recovery in East Asia's drylands. However, direct evidence of stilling effects on sand dunes is limited due to the lack of long‐term observational data.

UAV-SfM based field quantification of barchan dune celerity and morphodynamics in Gonghe Basin [PDF]
Barchan dunes do not often coexist with grasslands. However, in Gonghe Basin, north-eastern part in Qinghai-Tibetan Plateau (QTP), China, many barchan dunes are distributed on the grassland at high altitude.

Barchan dunes: Why they cannot be treated as 'solitons' or 'solitary waves'
, 2005 Schwämmle and Herrmann (Nature, 2003, vol. 426, p. 619) have suggested that two sub-aerial barchan sand dunes could 'pass through one another while still preserving their shape' in a manner similar to solitons or solitary waves. A wide range of published
