We studied the natural feeding patterns of dromedaries (Camelus dromedarius) in 2 Saharan rangelands in the Ouargla region of Algeria. More specifically, we directly observed (using a camcorder) the daily consumption of vegetation by 3 females during the fall of 2017 and the winter of 2018. The results showed that, on a given day, the dromedaries s...

Actinobacteria are known for their metabolic potential of producing diverse secondary metabolites such as antibiotics. Actinobacteria also playimportant roles in biogeochemical cycling and how soils develop. However, little is known about the effect of the vegetation type on the actinobacterial community structures in soils from arid regions. For t...

The study presents the quantification of changes in agroclimatic conditions for the growth of varieties of cotton, spring wheat, and spring barley in Central Asia by the middle of the 21st century. The quantification is based on the ensemble of future climate projections provided by the regional climate model with the resolution of 25 km. The IPCC ...

AbstractSoil salinity is an increasing threat to agriculture and is a major factor in reducing plant productivity in arid and semi-arid regions. Knowledge of the transport process of mass and energy in subsurface soil is vital for understanding the environmental and economic impact of agricultural practices in these areas. A finite difference model...

Based on the precipitation samples and meteorological data simultaneously collected during individual precipitation events at the Gulang (2085 m a.s.l.) and Anyuan stations (2700 m a.s.l.) in Gulang, this article analyzes the temporal variation and local meteroic water lines and discusses the relationship between precipitation stable isotopes and t...

Millipede diversity in tropical regions, and in Mexico in particular, is still mostly unknown. A modest but recurrent source of new Mexican species is the colonization of exotic species, due to human activity. The invasive species Cylindrodesmus hirsutus Pocock, 1889 has spread from its area of origin in Indonesia or Melanesia and become a virtuall...

Long term and mid-term reservoir operation involves derivation of rule curves for optimal management of the available resource. The present work deals with reservoir operation in the Aurès arid region. As an example, Babar reservoir is selected to apply the proposed approach which estimates all the water balance terms, especially those which are ra...
ABSTRACT Homogeneity evaluations are usually performed on the total annual precipitation data, which often fails to detect non-homogeneity in seasonal precipitation. Furthermore, it is required to assess homogeneity using multiple methods as the performance of homogeneity testing methods depend on the distribution of the data. This is particularly ...
A collection of 514 stable isotope water samples from the Atacama Desert is being reassessed geostatistically. The evaluation reveals that adjacent Andean catchments can exhibit distinct δ18O and δ2H value ranges in meteoric waters, despite similar sample altitudes of up to 4000 m above sea level (a.s.l.). It is proposed that the individual topogra...

Arid and semiarid regions are characterized by a unique floristic composition and structural diversity of their plant communities. The goal of the present study is to investigate the effect of physical and chemical properties of soil on these characteristics of the arid region of Tabuk in Saudi Arabia. With β diversity, the variability of a plant s...
