... Eight rivers regulated by large dams located in three hydro-climatic zones along the Chilean latitudinal gradient. We performed a multi-temporal scale analysis of flow records and we used data from official gauging stations to characterise the non-altered and the altered river regimes to determine the magnitude and persistence of the hydrological alteration downstream from large dams in Chile. The ...

Abstract:
... Fingerprinting methods are widely used to quantify sediment provenance at a watershed scale. However, different fingerprinting methods often yield different estimates for the same watershed. The objectives are to discuss in detail the performance of five fingerprinting approaches, compare the efficiency of various solutions, and investigate the effects of the number of composite fingerprints and t ...

Abstract:
... Under climate warming, the frequency of dry-wet abrupt alternation (DWAA) events was largely increased at the global scale. In this study, we identified DWAA events, including dry-wet (D-W) alternation events and wet-dry (W-D) alternation events, based on the Standardized Precipitation Evapotranspiration Index (SPEI) for the Great Lakes Region of Central Asia (GLRCA), and analyzed temporal and spa ...

Abstract:
... Effective monitoring of mammal species is critical to their management. Thermal cameras may enable more accurate detection of nocturnal mammals than visual observation with the aid of spotlights. We aimed to measure improvements in detection provided by thermal cameras, and to determine how these improvements depended on ambient temperatures and mammal species. We monitored small to medium sized m ...

Abstract:
... This paper presents new data on the spatial organization of mound-builder groups in the India Muerta wetlands, Uruguay. This area presents the beginning of land architecture in the region (ca. 4800–5000 years BP), associated with more arid climate. This construction tradition continues and intensifies, mainly from ca 3000 years BP, from the establishment of warmer and damper conditions. New source ...

Abstract:
... Diet of Quedenfeldtia moerens was studied from March 2018 to April 2019, in the Arid Anti-Atlas Mountain in Morocco. This study was carried by a repetitive sampling of available prey in the field using pitfall traps and prey consumed by 130 lizards from fecal pellets. Analysis shows that lizard's diet was composed exclusively of arthropods with four major taxonomic groups: Formicidae, Coleoptera, ...

Abstract:
... The Central Asian dryland (CAD) and East Asian dryland (EAD) are typical drylands in the globe. They are characterized by less precipitation, with vulnerable and sensitive ecosystems. Although they are located in the heart of continent, precipitation in these regions has opposite patterns on the multi-decadal time scale. In this study, we focus on different responses of precipitation changes in th ...

Abstract:
... Rearing temperature is correlated with the timing and speed of development in a wide range of poikiloterm animals that do not regulate their body temperature. However, exceptions exist, especially in species that live in environments with high temperature extremes or oscillations. Drosophila pachea is endemic to the Sonoran desert in Mexico, in which temperatures and temperature variations are ext ...

In this study, the overall energy consumption and visual comfort of a switchable suspended particle device (SPD) smart window were investigated as part of the glazing integration of an adaptive building designed to consume less energy in a hot desert climate. A typical floor of a commercial office building in Riyadh was chosen for the energy and visual comfort simulation, which was based on Energy ...

Abstract:
... An inventory of ectoparasites was carried out on 120 young House martin living (Delichon urbica) in 18 nests in Tebessa province (South-Eastern Algeria). A total of 104 samples were collected and identified, nine species of ectoparsites, belonging to two classes: Arachnida and Insecta with relative abundance of 21.14% and 78.86% respectively. The identified species are: Ixodes lividus, Ixodes fron ...

Abstract:
... Access to drinking water is essential for many avian species in arid landscapes, especially in hot and dry periods when metabolic requirements for water increase. The role of fringing vegetation in facilitating surface water access by arid zone bird communities was investigated over a 14-month period during which water demand increased. Bird visitation to six long-lasting waterholes in the MacDonn ...

Abstract:
... Moth bean and guar are important rain-fed crops of the western arid region of India. The genetic improvement mostly realized through germplasm evaluation and selection has successfully increased the yield potential and stability. However, continued improvement has been hampered due to the inefficient or non-availability of crossing techniques for recombination breeding. We attempted direct pollina ...

Abstract:
... Evaporative cooling systems are the currently used technology for providing cooling to greenhouses in arid regions where typically the greenhouse is ventilated. However, they consume a large quantity of water to cool the air. A closed greenhouse is proposed that uses earth-air heat exchangers (EAHE) and fogging to control the interior temperature and relative humidity in a water-efficient manner. ...

... Local climate zones (LCZs) provide a comprehensive framework to examine surface urban heat islands (SUHIs), but information is lacking on their thermal contributions and spatial effects in different macroclimate cities. A standard framework for distinguishing between the cooling effect and heating effect and spatial effect analysis based on the LCZ scheme was conducted in five distinct macroclimat ...

Abstract:
... Potential evapotranspiration (PET) is an important factor that needs to be considered in regional water management and allocation; thus, the reasonable estimation of PET is an important topic in hydrometeorology and other related fields. There is evidence that increased CO₂ concentration alters the physiological properties of vegetation and thus affects PET. In this study, changes in PET with and ...
