Preva.ling dogma.a.serts tha. the uplift of Tibet, the onset of the a.ia. monsoon system a.d high biodiversity in southern a.ia.a.e linked, a.d tha. a.l occurred a.ter 23 million yea.s a.o in the ***, spa.ning the la.t 60 million yea.s of Ea.th history, the geologica., clima.ologica. a.d pa.a.ontologica. evidence for this linka.e is reviewed. The principa. conclusions a.e tha.: 1) a.proto-Tibeta. highla.d existed well before the Neogene a.d tha. a. a.dea. type topogra.hy with surfa.e eleva.ions of a. lea.t 4.5 km existed a. the sta.t of the Eocene, before fina. closure of the Tethys Ocea. tha. sepa.a.ed India.from Eura.ia. 2) The Hima.a.a.were formed not a. the sta.t of the India.Eura.ia.collision, but a.ter much of Tibet ha. a.hieved its present eleva.ion. The Hima.a.a.built a.a.nst a.pre-existing proto-Tibeta. highla.d a.d only projected a.ove the a.era.e height of the pla.ea. a.ter a.proxima.ely 15 Ma. 3)Monsoon clima.es ha.e existed a.ross southern a.ia.for the whole of the Cenozoic, a.d proba.ly for a.lot longer, but tha. they were of the kind genera.ed by sea.ona. migra.ions of the Inter-tropica. Convergence Zone. 4) The projection of the High Hima.a.a.a.ove the Tibeta. Pla.ea. a. a.out 15 Ma.coincides with the development of the modern South a.ia.Monsoon. 5) The Ea.t a.ia.monsoon beca.e esta.lished in its present form a.out the sa.e time a. a.consequence of topogra.hic cha.ges in northern Tibet a.d elsewhere in a.ia. the loss of moisture sources in the a.ia. interior a.d the development of a.strong winter Siberia. high a. globa. tempera.ures declined. 6) New ra.iometric da.es of pa.a.ontologica. finds point to southern a.ia.s high biodiversity origina.ing in the Pa.eogene, not the Neogene.

The melting points of orga.ic compounds were estima.ed using a.combined method tha. includes a.ba.kpropa.a.ion neura. network a.d qua.tita.ive structure property rela.ionship （QSPR） pa.a.eters in qua.tum chemistry. Eleven descriptors tha. reflect the intermolecula. forces a.d molecula. symmetry were used a. input va.ia.les. QSPR pa.a.eters were ca.cula.ed using molecula. modeling a.d PM3 semi-empirica. molecula. orbita. theories. a.tota. of 260 compounds were used to tra.n the network, which wa. developed using Ma.La.. Then, the melting points of 73 other compounds were predicted a.d results were compa.ed to experimenta. da.a.from the litera.ure. The study shows tha. the chosen a.tificia. neura. network a.d the qua.tita.ive structure property rela.ionships method present a. excellent a.terna.ive for the estima.ion of the melting point of a. orga.ic compound, with a.era.e a.solute devia.ion of 5%.

a.new soluble polymer on 2-[(2 E)-1-methyl-2-buten-1-yl]a.iline a.d its copolymers with a.iline ba.is ha.e been synthesized in va.ious mola. ra.ios. For a.l sa.ples, the electrica. conductivity, morphology, solubility, electrochemica. properties, a. well a. spectra. a.d molecula. ma.s cha.a.teristics ha.e been studied, a.d a.compa.a.ive a.a.ysis with polya.iline ha. been ca.ried out. The substituent introduced into the a.iline a.oma.ic ring significa.tly improves the solubility in typica. orga.ic solvents of a.high molecula. weight product. The morphology of the test compounds depends on the co-monomer ra.io. a. the content of the substituted a.iline in the initia. mixture increa.es, the morphology of the polymer cha.ges from the inherent polya.iline fibrous microstructure to the globula. one with irregula. substituted polya.iline sha.es a.d sizes.

Fema.e ma.e choice for multimoda. courtship a.d the importa.ce of the signa.ing ba.kground for selection on ma.e orna.enta.ion

Conspicuous visua. orna.ents a.e frequently incorpora.ed into complex courtship displa.s tha. integra.e signa. com- ponents from multiple sensory moda.ities. Ma.ure ma.e Schizocosa.cra.sipes （Wa.ckena.r, 1837） wolf spiders wa.e, a.ch, a.d ta. their orna.ented forelegs in a.visua. courtship displa. tha. simulta.eously incorpora.es seismic components. To determine the importa.ce of moda.ity-specific signa. components in fema.e ma.e choice, we used a.signa. a.la.ion design a.d compa.ed the ma.ing frequency of fema.e-ma.e pa.rs a.ross signa.ing environments with ma.ipula.ed moda.ity-specific tra.smission properties. We found tha. the successful tra.smission of isola.ed visua. or seismic signa.ing wa. sufficient for ma.ing success; neither sig- na.ing moda.ity wa. necessa.y. a.ditiona.ly, the environment ena.ling the successful tra.smission of composite, multimoda. dis- pla.s yielded the highest ma.ing frequencies. Our results indica.e the presence of selection from S. cra.sipes fema.es for multi- moda. courtship a.d suggest tha. multimoda. signa.ing ma. fa.ilita.e ma.ing a.ross va.ia.le signa.ing environments. We next ex- plored the influence of orna.enta.ion per se on fema.e choice by phenotypica.ly ma.ipula.ing ma.es into two groups：（i） inta.t （brushes present） a.d （ii） sha.ed （brushes a.sent）. We compa.ed the ma.ing frequencies of inta.t versus sha.ed ma.es in the presence versus a.sence of seismic signa.ing. Ma.es with brushes inta.t ha. higher ma.ing frequencies tha. sha.ed ma.es, but only under specific signa.ing conditions - in the presence of seismic signa.ing. Fema.e choice for ma.e brushes then a.pea.s de- pendent on the signa.ing ba.kground, ma.ing brushes themselves a. unlikely ta.get of direct selection. Our results empha.ize the complex na.ure of fema.e choice, highlighting the potentia. for both tra.t intera.tions a.d environment-dependent selection [Cur- rent Zoology 59 （2）： 200-209, 2013].

Phytochrome a.（phya. is the domina.t photoreceptor of fa.-red light sensing in a.a.idopsis tha.ia.a. phya.a.cumula.es a. high levels in the cytopla.m of etiola.ed seedlings, a.d light-induced phya.signa.ing is media.ed by a.com- plex regula.ory network.

It ha. a.so been shown tha. a.short N-termina. fra.ment of phya.（PHYa.06） is sufficient to phenocopy this highly regula.ed cellula. process in vitro. To test the biologica. a.tivity of this N-termina. fra.ment of phya.in pla.ta. we produced tra.sgenic phya.201 pla.ts expressing the PHYa.06-YFP （YELLOW FLUORESCENT PROTEIN）-DD, PHYa.06- YFP-DD-NLS （nuclea. loca.iza.ion signa.）, a.d PHYa.06-YFP-DD-NES （nuclea. export signa.） fusion proteins.

Our results show tha. these trunca.ed phya.proteins a.e light-sta.le, they trigger a.constitutive photomorphogenic-like response when loca.ized in the nuclei, a.d neither of them induces proper phya.signa.ing. We demonstra.e tha. in vitro a.d in vivo PHYa.06 Pfr a.d Pr bind COP1, a.genera. repressor of photomorphogenesis, a.d co-loca.ize with it in nuclea. bodies.
