Multilevel society is one of the most complex social systems in natural ecosystems and is a typical feature among some primates.Given the potential connection between social behavior and gut microbiome composition,the multilevel social system could affect the primate gut microbiome.Here,based on long-term observation(e.***.social unit dynamics,transfer,and behavior),we investigated this potential integrating 16S rRNA gene amplicon sequencing and behavior data in Yunnan snub-nosed monkeys(Rhinopithecus bieti),which possess a multilevel social group based on one male units(OMUs,each unit with several breeding females and their offspring)and all-male unit(AMU,several bachelor males residing together).We found that the mean unweighted Unifrac distance between adult males from different OMUs was significantly lower than that between adult females from different OMUs(paired Wilcoxon test,P=0.007).There was no significant difference in the mean unweighted Unifrac distance between females within the same OMU or between females from different OMUs.These findings indicated the potential connection between the defense and invasion of social units and the gut microbiome community in wild Yunnan snub-nosed monkeys.We speculated that the resident males of OMUs displaying a significantly higher similarity in the gut microbial community than that of adult females in separate OMUs might be associated with the sexual differences in their interactions and from previously having cohabitated together in the AMU.Therefore,this study suggested that multilevel societies might have an effect on the gut microbial community in this wild nonhuman primate species.

Sex-biased dispersal is common in group-living animals.Due to differences in local demographic and environmental factors,sex-biased dispersal presents many irregular patterns.In this study,a habituated,individually identified Yunnan snub-nosed monkey Rhinopithecus bieti group was observed over 9 years;192 dispersal events,including 97 male dispersal events(25 natal dispersal and 72 secondary dispersal)and 95 female dispersal events(34 natal dispersal and 61 secondary dispersal)were observed.Males and females showed different dispersal paths,dispersal ages,and dispersal patterns.Females had 2 dispersal paths,whereas males had 4 paths.In terms of age of dispersal,the male age of natal dispersal was younger than for females.Males prefer single dispersal,whereas females prefer parallel dispersal.Our study indicates that the dispersal pattern of R.bieti should be classified as a bisexual dispersal pattern.The differences in dispersal path,average age at dispersal,and dispersal path pattern indicate that Yunnan snub-nosed monkeys may still retain a loose matrilineal social system.

Spatial-temporal shifting patterns and in situ conservation of spotted seal(Phoca largha)populations in the Yellow Sea ecoregion

Understanding the habitat shifting pattern is a prerequisite for implementing in situ conservation of migratory species.Spotted seals(Phoca largha)inhabiting the Yellow Sea ecoregion(YSE)comprise a small population with independent genes and represent a charismatic flagship species in this region.However,this population has declined by 80%since the 1940s,and increased support from the countries around the YSE is urgently needed to address the potential local extinction risk.A time-series niche model and life-history weighted systematic conservation planning were designed on the basis of a satellite beacon tracking survey(2010–2020)of the YSE population.The results showed clustering and spreading shifting patterns during the breeding and migratory seasons,respectively.The closed-loop migration route formed in the YSE indicated that this population might be geographically isolated from populations in other breeding areas around the world.The conservation priority area(CPA),with an area of 19632 km^(2)(3.58%of the total YSE area),was the most effective response to the potential in situ risk.However,nearly 80%of the CPA was exposed outside the existing marine protected areas(MPAs).Future establishment of MPAs in China should strategically consider the conservation gap identified herein,and it is recommended for Korea’s closed fishing season to be spatially set in the western Korean Peninsula from May to August.This study also exemplified that the lack of temporal information would lead to the dislocation of niche modeling for migratory species represented by spotted seals.Attention should be paid to protecting small and migratory populations in marine biodiversity conservation planning.

Methodological progress in trace amounts of structural water in nominally anhydrous minerals

Science China Earth Sciences 2016年第5期59卷 901-909页

In the deep Earth, hydrogen mainly occurs as structural hydroxyl and molecular water in minerals and melts, constituting mobile and immobile aqueous components. Hydrous minerals contain hydrogen which occupies a specific structural position and constitutes an indispensable component of chemical formulae. On the other hand, nominally anhydrous minerals do not contain hydrogen in their chemical formulae, but can host trace amounts of water in structural position and lattice defect. The molecular water may occur in the lattice defect as fluid/melt inclusions in minerals. Even though the water content of nominally anhydrous minerals is very limited generally in the order of ppm(parts per million), they may play a significant role in influencing the physicochemical properties of mineral and rock systems. With the continuous improvement of modern instrumentations, the analytical methodology exhibits trends for higher spatial resolution, lower detection limit and integral multiple methods on the water amount and its isotopic ratio. Among these methods, Fourier transform infrared spectrometry remains the most widely used, while secondary ion mass spectrometry, continuous flow mass spectrometry, elastic recoil detection analysis and Raman spectrometry are promising. This paper provides a brief review on the methodological progress and their applications to the analysis of structural water in nominally anhydrous minerals.

Dehydration at subduction zones and the geochemistry of slab fluids

Subducting oceanic slabs undergo metamorphic dehydration with the increase of temperature and pressure during subduction.Dehydration is an essential step for element recycling,and slab fluids are critical agents for mediating slab-mantle interaction.Dehydration is mainly controlled by the thermal structure of subduction zones and the stability of hydrous minerals.At fore-arc depths,slab dehydration produces aqueous fluid with dissolved salts such as NaCl.As subduction proceeds deeper,the content of silicate components increases.At sub-arc and post-arc depths,a hydrous silicate melt is likely to form,or a supercritical fluid could arise from complete miscibility between silicates and H_(2)O.The partitioning of elements between slab fluid and the residual solid rock is controlled by the type of fluid,and generally it is the supercritical fluid that is the most capable of mobilizing trace elements,being an effective carrier even for high field strength elements.Understanding the chemistry of slab fluids relies on sophisticated integration of experiments,theoretical computation and investigation of natural rock samples.This contribution focuses on the content and speciation of key volatiles,including carbon,nitrogen and sulfur,in slab fluids as well as important fluid properties such as oxygen fugacity and acidity.The properties of slab fluids show complicated variation under the control of mineral assemblages and T-P conditions.Slab fluids at great depths of subductions have been inferred to be modestly alkaline and not necessarily very oxidizing as often assumed.Further progress in the research of slab dehydration and the chemistry and properties of slab fluids demands urgently the development of innovative experimental and computational technology including in situ analytical methods at high T-P.

Giant enhancement of photoluminescence quantum yield in 2D perovskite thin microplates by graphene encapsulation

The optoelectronic performances of the layered materials are strongly dependent on the thickness of the samples due to the surface effect.As the size of the samples decreases to few nanometers,the surface depletion field and surface defect density are prominent arising from the large surface to volume ratio.For instance,thin two-dimensional(2D)organic-inorganic hybrid perovskite microplates usually exhibit a rather low photoluminescence quantum yield(PLQY),owning to the strong surface effect.Here,we report that the PLQY can be enhanced as large as 28 times in(iso-BA)2Pbl4(BA=C4H9NH3)2D perovskite thin microplates encapsulated by graphene,resulting in that the PLQY is more than 18%for the microplate with a thickness of 6.7 nm at 78 K.As the thickness of the 2D perovskite microplate increases,the enhancement is gradually reduced and finally vanishes.This observation is in striking contrast to that in monolayer transition metal dichalcogenides(TMDs),when the PLQY is quenched by covering a layer of graphene due to the efficient charge transfer.The enhancement of PLQY in 2D perovskites can be mainly ascribed to the reduced quantum confined Stark effect(QCSE)due to the reduced surface depletion field after covering graphene flake,resulting in the enhanced radiative recombination efficiency.Our findings provide a cost-effective approach to enhance the luminescence,which may pave the way toward high performance light emitting devices based on 2D perovskites.

Tight multi-medium oil reservoirs are the main source of hydrocarbon resources around the world.Acid fracturing is the most effective technology to improve productivity in such reservoirs.As carbonates are primarily composed of dolomite and calcite,which are easily dissolved by hydrochloric acid,high-permeability region will be formed near the well along with the main artificial fracture when acid fracturing is implemented in tight multi-medium oil reservoirs.In this study,a comprehensive composite linear flow model was developed to simulate the transient pressure behavior of an acid fracturing vertical well in a naturally fractured vuggy carbonate reservoir.By utilizing Pedrosa's substitution,perturbation,Laplace transformation and Stehfest numerical inversion technol-ogy,the pressure behavior results were obtained in real time domain.Furthermore,the result of this model was validated by comparing with those of previous literature.Additionally,the influences of some prevailing parameters on the type curves were analyzed.Moreover,the proposed model was applied to an acid fracturing well to evaluate the effectiveness of acid fracturing measures,to demonstrate the practicability of the proposed model.

Chinese Journal of Cancer 2013年第5期32卷 266-269页

作者： Xiu-Li Bi wancai Yang School of Life Science Liaoning University Department of Pathology Xinxiang Medical University Department of Pathology University of Illinois at Chicago

Decorin is a member of the extracellular matrix small leucine-rich proteoglycans family that exists and functions in stromal and epithelial cells. Accumulating evidence suggests that decorin affects the biology of various types of cancer by directly or indirectly targeting the signaling molecules involved in cell growth, survival, metastasis, and angiogenesis. More recent studies show that decorin plays important roles during tumor development and progression and is a potential cancer therapeutic agent. In this article, we summarize recent studies of decorin in cancer and discuss decorin′s therapeutic and prognostic value.
