This review upd.tes the present status of the field.of molecular markers and.marker-assisted.selection(MAS),using the example of d.ought tolerance in *** accuracy of selected.quantitative trait loci(QTLs),cand.d.te genes and.suggested.markers was assessed.in the barley genome *** common strategies are d.scribed.for molecular marker d.velopment,cand.d.te gene id.ntification and.verification,and.their possible applications in MAS to improve the grain yield.and.yield.components in barley und.r d.ought *** strategies are based.on the following five principles:(1)Molecular markers are d.signated.as genomic‘tags’,and.their‘pred.ction’is strongly d.pend.nt on their d.stance from a cand.d.te gene on genetic or physical maps;(2)plants react d.fferently und.r favourable and.stressful cond.tions or d.pend.ng on their stage of d.velopment;(3)each cand.d.te gene must be verified.by confirming its expression in the relevant cond.tions,e.g.,d.ought;(4)the molecular marker id.ntified.must be valid.ted.for MAS for tolerance to d.ought stress and.improved.grain yield.and.5)the small number of molecular markers realized.for MAS in breed.ng,from among the many stud.es targeting cand.d.te genes,can be explained.by the complex nature of d.ought stress,and.multiple stress-responsive genes in each barley genotype that are expressed.d.fferentially d.pend.ng on many other factors.

Recovery of Brachiopod.and.Ammonoid.Faunas Following the End.Permian Crisis:Ad.itional Evid.nce from the Lower Triassic of the Russian Far East and.Kazakhstan

After the End.Permian mass extinction, ammonoid. reached.levels of taxonomic d.ver- sity higher than in the Changhsingian by the d.enerian Substage of the Ind.an. However, brachiopod. exhibit a prolonged.d.lay in recovery, and.their taxonomic d.versity had.not recovered.to Late Permian levels even by the Olenekian. The d.fferential patterns of recovery between these two clad.s may reflect fund.mental d.fferences in physiology and.behavior. Brachiopod. were benthic organisms that were d.pend.nt on specific trophic sources, and.their general red.ction in size d.ring the Early Triassic may have been a response to a relative paucity of food.resources. In contrast, ammonoid. were sluggish- nektic organisms that utilized.a wid.r range of trophic sources and.that suffered.no comparable size d.crease d.ring the Early Triassic. Brachiopod. may have been at a d.sad.antage also d.e to vulner- abilities associated.with their larval stage, d.ring which they had.to locate a suitable substrate for set- tlement. In contrast, ammonoid. had.no larval stage and.juveniles may have been d.spersed.wid.ly into favorable habitats. These factors may account for d.fferences in the relative success of ammonoid. and.brachiopod. at high-latitud. regions following the End.Permian mass extinction： ammonoid. success- fully reeolonized.the Boreal region d.ring the Early Triassic whereas brachiopod. d.d.not.

A NUMERICAL METHOd.FOR THE SIMULATION OF FREE SURFACE FLOWS OF VISCOPLASTIC FLUId.IN 3d

引用

Journal of Computational Mathematics 2011年第6期29卷 605-622页

作者： Kirill d. Nikitin Maxim A. Olshanskii Kirill M. Terekhov yuri V. Vassilevski Institute of Numerical Mathematics Russian Academy of Sciences Moscow Russia d.partment of Mechanics and.Mathematics Moscow State University Moscow Russia

In this paper we stud. a numerical method.for the simulation of free surface flows of viscoplastic （Herschel-Bulkley） fluid.. The approach is based.on the level set method.for capturing the free surface evolution and.on locally refined.and.d.namically ad.pted.octree cartesian staggered.grid. for the d.scretization of fluid.and.level set equations. A regu- larized.mod.l is applied.to hand.e the non-d.fferentiability of the constitutive relations. We consid.r an extension of the stable approximation of the Newtonian flow equations on staggered.grid.to approximate the viscoplastic mod.l and.level-set equations if the free bound.ry evolves and.the mesh is d.namically refined.or coarsened. The numerical method.is first valid.ted.for a Newtonian case. In this case, the convergence of numerical solutions is observed.toward. experimental d.ta when the mesh is refined. Further we compute several 3d.viscoplastic Herschel-Bulkley fluid.flows over incline planes for the d.m-break problem. The qualitative comparison of numerical solutions is d.ne versus experimental investigations. Another numerical example is given by computing the freely oscillating viscoplastic d.oplet, where the motion of fluid.is d.iven by the surface tension forces. Altogether the consid.red.techniques and.algorithms （the level-set method. compact d.scretizations on d.namically ad.pted.octree cartesian grid., regularization, and.the surface tension forces approximation） result in efficient approach to mod.ling viscoplastic free-surface flows in possibly complex 3d.geometries.

The Kamenushka Formation, exposed.in the northern part of South Primorye （Kamennshka-1 and.Kamenushka-2 sections）, is one of the few localities in the world.with richly fossiliferous Lower-Upper Olenekian sed.mentary successions. Lower to Mid.le Triassic ammonoid., brachiopod. and.conod.nt-bearing silty-clayey d.posits of the Kamenushka-1 and.Kamenushka-2 sections have been isotope-geochemically investigated.in d.tail. As a result, these sections, together with the previously investigated.Abrek Section, exposed.in the southern part of South Primorye, provid. almost complete ^15Non- and.^13Corg- record. for the Lower Triassic of this region. Nine N- isotope intervals and.the five negative C-isotope excursions, reflecting, apparently, unstable climatic and.hyd.ological cond.tions, have been d.stinguished.in the Lower Triassic of South Primorye. On the basis of the new C-isotope d.ta the Mesohed.nstroemia bosphorensis Zone （upper part）, Shimanskyites shimanskyi and.Neocolumbites insignis zones of South Primorye are correlated.now with the Lower Smithian part of the Yinkeng Formation, the Upper Smithian part of the Helongshan Formation and.the Mid.le Spathian part of the Nanlinghu Formation in South China, respectively, as has been observed.in the Abrek, Kamenushka-2, West Pingd.ngshan and.Majiashan sections.

To show paleontological characteristics of the Olenekian-Anislan bound.ry bed. in the Russian Far East, a review of new d.ta on the Upper Olenekian and.Lower Anisian biostratigraphy of South Primorye is given on the basis of five sections： Golyi Cape, Petrovka River, Zhitkov Peninsula, Tchernyschew Bay and.Atlasov Cape, using new ammonoid. brachiopod.and.conod.nt find.ngs. The most representative ammonoid.assemblage at the base of the Anisian was d.scovered.in the Ussuriphyllites amurensis Zone （10.6 m thick） of the Atlasov Cape Section： Parasageceras sp. nov., Prionitid.e gen. et sp. nov. , Ussuriphyllites amurensis （Kiparisova）（d.minant）, Megaphyllites atlasoviensis za.ha.ov, Leiophyllites praematurus Kiparisova, Leiophyllites sp. , Ussurites sp. , Parad.nubites sp. ind.t., Paracrochord.ceras sp. nov., Prohungarites popowi Kiparisova, Arctohungarites primoriensis za.ha.ov, A. solimani （Toula）, Salterites sp. ind.t. （gigantic shell）, and.Tropigastrites sublachontanus za.ha.ov. Conod.nts Neospathod.s cf. homeri （Bend.r） were found.in the lower part of the Ussuriphyllites amurensis Zone of the Atlasov Cape. The Atlasov Cape seems to be one of the very promising sections of the Russian Far East for d.tailed.investigation of the Olenekian-Anisian bound.ry.
