“…For oasis-dependent species, the oasis edge is the boundary between the oasis and desert [15]. Vegetation coverage and species diversity are typically lower near the oasis edges than in the central area [16]; the former directly influences insect density and, thus, the resources available to insect-eating birds [17].…”

Nesting-site selection is an important aspect of the breeding process in birds, as it usually determines nesting and breeding successes. Many factors can affect bird nest-site selection, including anthropogenic disturbance. In an extreme desert environment, such as the Taklamakan Desert in China, birds’ survival pressure is high, especially for rare species such as the Xinjiang Ground-jay (Podoces biddulphi). We studied nest-site selection in this species from March 2017 to May 2019. A Chi-square test, independent sample t-test, Mann–Whitney U-test, and generalized linear models were applied to possible nest-site selection factors for Xinjiang Ground-jays. The main determining factors were the distances to human settlements, water, and the edge of the oasis. Xinjiang Ground-jays nested near available water resources for easier access, which is important in arid environments. Individuals chose to nest far from the oasis edges and settlements to increase food availability and reduce interference from human activities, respectively. Overall, water, food availability, and anthropogenic influence were the main factors affecting the nest-site selection of Xinjiang Ground-jays in this study. Therefore, these results suggest that there is a trade-off between survival and reproduction. Further studies are required to verify whether similar site preferences may also apply to other desert-dwelling species.

IntroductionThe precipitation pattern has changed significantly in arid desert areas, yet it is not clear how the water use strategies of Tamarix ramosissima Ledeb. on coppice dunes along a natural precipitation gradient are affected.MethodsIn this study, the hydrogen and oxygen isotope compositions of xylem water, soil water, precipitation, and groundwater were measured by stable isotope techniques in Huocheng, Mosuowan, and Tazhong. Additionally, the water use strategies of natural precipitation gradient were investigated in conjunction with the MixSIAR model.ResultsThe results indicated that the water sources of T. ramosissima exhibited significant variation from semi-arid to hyper-arid areas. In semi-arid areas, T. ramosissima mainly absorbed shallow, shallow-middle, and middle soil water; however, T. ramosissima shifted its primary water sources to middle and deep soil water in arid areas. In hyper-arid areas, it mainly utilized deep soil water and groundwater. In contrast, the water source contribution rate of T. ramosissima exhibited relative uniformity across each layer in an arid area. Notably, in hyper-arid areas, the proportion of groundwater by T. ramosissima was significantly high, reaching 60.2%. This is due to the relatively shallow groundwater supplementing the deep soil water content in the area. In conclusion, the proportion of shallow soil water decreased by 14.7% for T. ramosissima from semi-arid to hyper-arid areas, illustrating the occurrence of a gradual shift in potential water sources utilized by T. ramosissima from shallow to deep soil water and groundwater.DiscussionTherefore, T. ramosissima on coppice dunes shows flexible water use strategies in relation to precipitation and groundwater, reflecting its strong environmental adaptability. The findings hold significant implications for the conservation of water resources and vegetation restoration in arid areas.
