“…Previous studies have addressed the effects of converting natural grassland to irrigated cropland or tree plantations on the structure and diversity of ground arthropod communities (Li et al ., ; Feng et al ., ). Nevertheless no studies have investigated how different types of shrub shelterbelts established around oases will affect the abundance, species richness and community composition of ground beetles, a dominant group of arthropods in China's arid ecosystems (Ren & Yu, ; Liu et al ., ).…”

Oases in arid regions of northwestern China are main sites for agriculture and human settlement. Conservation of these important oasis habitats involves establishing shrub shelterbelts around the oases. We investigated how different types of shrub shelterbelts affect the diversity of ground beetles. We sampled carabid and tenebrionid assemblages with pitfall traps in spring and summer and measured key environmental variables in four habitats of the arid region: planted stands of pure and mixed plantations of two long‐lived shrubs (Haloxylon ammodendron and Tamarix ramosissima) and natural grassland (NG) from which planted systems were converted. Beetle abundance and species richness reduced significantly in the pure plantations but the mixed plantation had similar abundance and higher richness in spring and lower richness in summer relative to NG. We found differences in response between functional groups of beetles. The pure plantations resulted in reduced abundance and richness of herbivores and detritivores and increased predator abundance in spring and reduced predator abundance in summer. The mixed plantation resulted in increased detritivore richness in spring and reduced detritivore richness in summer as well as increased herbivore abundance in spring and reduced herbivore and predator abundance and richness in summer. The beetle community was largely determined by shrub cover and herbaceous plant diversity. We conclude that the pure shrub plantations reduce beetle diversity, whereas the mixed shrub plantation has less adverse effect on beetle diversity. Shrub mixtures can therefore be a practical measure to minimise the negative impacts of shrub shelterbelts on beetles.

“…Although many attempts have exploited the adaptation mechanism in the species with known genome sequences, the molecular basis of adaptation in the non-genomic species is still poorly understood [1], [2], especially in the plants from arid regions which contain plenty of potential genetic resources for ecology engineering. As pioneer and constructive species in all kinds of desert ecosystems, Reaumuria plants play important roles to sustain fragile desert ecosystems by keeping the vital process of the transport of energy and substances [3]–[5], and preventing from wind erosion, sand drifting and the further desertification of these regions [3], [6]–. These plant species were widely used as fine pioneer plants in the restoration of degraded ecosystems with natural rainfall [9] and in the sustainable development of arid regions due to their extreme tolerance to saline-alkaline conditions [10]–[12].…”

Background Reaumuria soongorica is an extreme xerophyte shrub widely distributed in the desert regions including sand dune, Gobi and marginal loess of central Asia which plays a crucial role to sustain and restore fragile desert ecosystems. However, due to the lacking of the genomic sequences, studies on R. soongorica had mainly limited in physiological responses to drought stress. Here, a deep transcriptomic sequencing of R. soongorica will facilitate molecular functional studies and pave the path to understand drought adaptation for a desert plant.Methodology/Principal FindingsA total of 53,193,660 clean paired-end reads was generated from the Illumina HiSeq™ 2000 platform. By assembly with Trinity, we got 173,700 contigs and 77,647 unigenes with mean length of 677 bp and N50 of 1109 bp. Over 55% (43,054) unigenes were successfully annotated based on sequence similarity against public databases as well as Rfam and Pfam database. Local BLAST and Kyoto Encyclopedia of Genes and Genomes (KEGG) maps were used to further exhausting seek for candidate genes related to drought adaptation and a set of 123 putative candidate genes were identified. Moreover, all the C4 photosynthesis genes existed and were active in R. soongorica, which has been regarded as a typical C3 plant.Conclusion/SignificanceThe assembled unigenes in present work provide abundant genomic information for the functional assignments in an extreme xerophyte R. soongorica, and will help us exploit the genetic basis of how desert plants adapt to drought environment in the near future.

“…Spring and late summer peaks in soil fauna populations might also be related to the increased activity in root and fungal growth, which provides ample food sources for most soil animals. Given the pattern of climate in this area, variations of soil fauna population density were primarily affected not only by heavy rainfall in monsoonal seasons, but also by drought and low temperature in winter, which may cause the abiotic changes that markedly influence the phenology of soil mite assemblages and their feeding activities (J. L. Liu, Li, Liu, & Liu, ; Sackmann & Flores, ). For instance, Psocoptera, a humidity‐limited distribution taxon, was found only in April and July in the four experimental sites.…”
