Purpose Although the formation mechanism of the megadunes in the Badain Jaran Sand Sea has received considerable research attention, their provenance and sand accumulation processes are still poorly understood. Therefore, this study aims to identify the provenance of the megadunes and clarify the spatial and temporal characteristics of their source...
Understanding the relation between terrestrial microorganisms and edaphic factors in the Antarctic can provide insights into their potential response to environmental changes. Here we examined the composition of bacterial and micro-eukaryotic communities using amplicon sequencing of rRNA genes in 105 soil samples from the Sor Rondane Mountains (Eas...
В работе проанализированы особенности различных видов растений, применяемых или планируемых для использования в целях закрепления песков в пустыне Аралкум на территории Республики Узбекистан. / The article analyzes the features of various plant species used or planned for use in order to consolidate the sands in the Aralkum desert on the territory ...
Fluvial and gobi sediments play significant roles in the formation of modern sand seas and their evolution. However, little is known about their respective source contributions, especially in quantitative terms. In the present study, we selected the Badain Jaran Sand Sea in Northwest China to quantitatively identify the sediment sources. To achieve...
Understanding the impacts of environmental factors on spatial–temporal and large-scale rodent distribution is important for rodent damage prevention. Investigating rat hole density (RHD) is one of the most effective methods to obtain the intensity of rodent damage. However, most of the previous field surveys or UAV-based remote sensing methods can ...
The aim of this paper is to assess the potential use of data recorded by the Global Navigation Satellite System Reflectometry (GNSS-R) Cyclone Global Navigation Satellite System (CYGNSS) constellation to characterize desert surface roughness. The study is applied over the Sahara, the largest non-polar desert in the world. This is based on a spatio-...

© 2019 Elsevier Ltd This study investigates the effect of soiling on the cooling capacity of the wind and its consequences for the performance of photovoltaic modules. Cooling and electrical characteristics were measured on a glass-glass module for wind speeds up to 4 ms−1 and soiling levels up to 41 gm−2. Soiling can promote the cooling of photovo...
Eriosyce is one of most species‐rich genera within Notocacteae (Cactaceae) harboring a variety of stem and flower morphologies, and fruits with basal abscission. The lack of a well‐sampled molecular phylogeny contributes to the current taxonomic instability of the genus, where its circumscription and infrageneric classification has been questioned....
Alluvial fans are important depositional landforms that offer valuable records of terrestrial sedimentation history if their surfaces can be mapped and dated accurately. Unfortunately, as this often depends on detailed field mapping and intensive absolute dating techniques, it can be a challenging, expensive and time-consuming exercise. In this stu...
