The Zongwulong Shan-Qinghai Nanshan tectonic belt of the northern Tibet Plateau experienced a protracted tectonic history， including the openings and closures of the Proto- and Paleo-Tethyan Oceans. Although the tectonic belt has been extensively studied， details regarding the tectonic processes involved in its development remain controversial. To better constrain the tectonic processes of this tectonic belt， we conducted detailed field geological mapping， zircon U-Pb geochronology， and whole-rock geochemical and Sr-Nd isotopic analyses. Our results show that intrusive rocks in the tectonic belt crystallized in ca. 292–233 ma， perhaps in an arc/subduction setting. Geochemical and Sr-Nd isotopic data suggest that early Permian–late Triassic ultramafic-intermediate intrusions were sourced from the enriched mantle， whereas intermediate-acidic rocks were sourced from mixed crust-mantle. We present the tectonic model that involves: (1) Early Devonian–early Permian intracontinental extension occurred in the northern margin of the Qaidam continent (ca. 416 ma–292 ma); (2) Early Permian–late Triassic northward subduction of the Paleo-Tethyan Ocean resulted in arc magmatism (ca. 292 ma–233 ma); and (3) subsequent late Triassic intracontinental extension (ca. 233 ma–215 ma). Our results suggest that the late Paleozoic–early Mesozoic development of the Zongwulong Shan-Qinghai Nanshan was related to the opening， subduction， and slab retreat of the Paleo-Tethyan Ocean， which has key implications for the tectonic evolution of the northern Tibetan Plateau.

为探究海洋生物活性肽对厚壳贻贝(Mytilus coruscus)生长发育的影响,本研究以厚壳贻贝稚贝为实验对象,通过投喂不同浓度的贻贝肽(0、7、9、10、70和90 mg/L),测定壳长、壳高、湿重等指标,以确定最适贻贝肽浓度,并对投喂前后的稚贝微生物群落进行分析,实验周期为56 d。结果显示,相较于未投喂贻贝肽的对照组,投喂9 mg/L的贻贝肽显著促进稚贝生长,且壳长、壳高和湿重分别提升了27.37%、32.35%和115.49%;同时发现,高浓度贻贝肽(70 mg/L和90 mg/L)对厚壳贻贝稚贝产生了致死效应。通过16S rRNA基因扩增和测序对比分析了28 d和56 d贻贝肽投喂组与未投喂组的厚壳贻贝稚贝微生物组群落结构变化。研究结果显示,投喂9 mg/L贻贝肽改变了稚贝微生物群落结构组成,提高了拟杆菌门(Bacteroidota)和变形菌门(Proteobacteria)的丰度,降低了放线菌门(Actinobacteriota)的丰度;同时,属水平分析发现,贻贝肽投喂组有效增加了鲁杰氏菌属(Ruegeria)、黏着杆菌属(Tenacibaculum)、居海杆菌属(maribacter)、栖砂杆菌属(Arenibacter)、十八碳杆菌属(Octadecabacter)和希瓦氏菌属(Shewanella)等有益菌的物种丰度,显著减少了红球菌属(Rhodococcus)、气单胞菌属(Aeromonas)等潜在致病菌的丰度。综上,贻贝肽能有效促进厚壳贻贝的稚贝生长发育,并且可以优化厚壳贻贝微生物群落结构,研究成果将为后续开展贻贝肽等海洋生物活性肽对贝类稚贝中间培育以及海水贝类养殖可持续发展提供基础和数据支撑。

Haloxylon ammodendron （C. A. Mey.） is one of the economically and ecologically important desert trees used for sand fixation. The ovary of H. ammodendron is found not to swell after flowering in spring until at the end of August or early September in western China. However, what happens for ovary at anatomic level in that period and which crucial ecological factor regulates the phenomenon of H. ammodendron have not been fully understood. To characterize the phenomenon and explore the crucial environmental regulating factors, we carried out the morphological and anatomic observations at the different development stages of the fruits and three single-factor experiments （low air temperature, sufficient soil moisture, and short day length）. Our results showed that under the natural conditions, the ovary of H. ammodendron after flowering developed slowly and the morphological changes of fruits were not significant for the period from may to August and after late August or early September; and then the ovary developed rapidly and matured in October. Cell division in embryo was observed to start approximately 25 days after flowering （DAF） and just developed to globular embryo stage at mid-August. Photoperiod was identified as the pivotal environmental factor regulating the fruit development of H. ammodendron. Moreover, the threshold value of day length for the fruit development was 14.0 h. A long day （〉14.0 h） treatment began from 5 DAF could delay fruit development of H. ammodendron while a short day （〈14.0 h） treatment could accelerate it. Moreover, a further longer day treatment （〉15.0 h） could also delay fruit development even when they had developed for a long time （110 DAF）. The present study indicated that H. ammodendron adopted a reproductive strategy of delayed fruit development and this strategy helps it survive and obtain offspring in harsh desert habitats.

Here, we report the construction of magnetic core-shell microparticles for oil removal with thermal driving regeneration property. Water-in-oil-in water (W/O/W) emulsions from microfluidics are used as templates to prepare core-shell microparticles with magnetic holed poly (ethoxylated trimethylolpropane triacrylate) (PETPTA) shells each containing a thermal-sensitive poly (N-Isopropylacrylamide) (PNIPAM) core. The microparticles could adsorb oil from water due to the special structure and be collected with a magnetic field. Then, the oil-filled microparticles would be regenerated by thermal stimulus, in which the inner PNIPAM microgels work as thermal-sensitive pistons to force out the adsorbed oil. At the same time, the adsorbed oil would be recycled by distillation. Furthermore, the adsorption capacity of the microparticles for oil keeps very stable after 1st cycle. The adsorption and regeneration performances of the microparticles are greatly affected by the size of the holes on the outer PETPTA shells, which could be precisely controlled by regulating the interfacial forces in W/O/W emulsion templates. The optimized core-shell microparticles show excellent oil adsorption and thermal driving regeneration performances nearly without secondary pollution, and would be a reliable green adsorption material for kinds of oil.
