Backgr.und: Postzygotic isolation in the for. of r.duced viability and/or.fer.ility of hybr.ds may help maintain species boundar.es in the face of inter.pecific gene flow. Past hybr.dization events between house spar.ows(Passer.domesticus) and Spanish spar.ows(P. hispaniolensis) have given r.se to a homoploid hybr.d species, the Italian spar.ow(P. italiae). Although genetic incompatibilities ar. known to isolate these thr.e species, the biological consequences of these incompatibilities ar. still unknown in ear.y gener.tion ***: We investigated whether.F1 hybr.ds between house and Spanish spar.ows exper.ence r.duced viability or.fer.ility. Mor. specifically, we gener.ted hybr.ds thr.ugh contr.lled cr.sses in aviar.es, and compar.d ovar.es of female hybr.ds with female of pur.?species ***: We found that over.ll, hybr.d ovar.es wer. under.eveloped and that half of all female hybr.ds exhibited symptoms of ovar.an hypofunction(ovar.an atr.phy and complete absence of developed follicles).Conclusions: Fer.ility in hybr.ds is a common consequence or.post?zygotic bar.ier. between species. We discuss these r.sults in light of pr.vious findings on genetic incompatibilities between the par.nt species and the potential r.le of incompatibilities in hybr.d speciation, a r.r. evolutionar. pr.cess in bir.s.

New total or.anic car.on （TOC） data fr.m the two Or.ovician-Silur.an tr.nsitional gr.ptolite-bear.ng black shale inter.als, the Wufeng （五峰） For.ation and the Longmaxi （龙马溪） For.ation in Centr.l Guizhou （贵州） and West Hubei （湖北）, r.spectively, as well as pr.viously r.por.ed TOC data fr.m the same inter.als in other.places on the Yangtze platfor. of South China, have been used to pr.duce an initial estimate of the pr.mar. paleopr.ductivity via a conventional inver.e method （i.e., ***）. The values of the *** ar. estimated to be 32 （43-21） gC/（m^2·a）（Wufeng For.ation） and 21 （27-16） gC/（m^2·a）（Longmaxi For.ation）. Also, simultaneously, the habitat types （i.e., HT; cf., BA： benthic assemblage） and their.tempor.l and spatial changes have been documented fr.m the same succession, and an initial estimate of the pr.mar. paleopr.ductivity has been pr.duced using a for.ar. method （i.e., r.p-for.ar.） Beingbounded mainly by the per.tidal to inner.shelf envir.nment shelly-facies or.mixed-facies successions with BA1 to BA3 faunas both at the top and the base, which indicates the habitat types fr.m HT Ⅱ to HT Ⅲ2, the biohabitat type of the two gr.ptolite-bear.ng black shale inter.als can be limited to HT III to HT IV, cor.esponding to the inner.shelf to the outer.shelf, with depths fr.m r.ughly 60 m to 200-300 m. Based on the cur.ent data fr.m the South China Sea and the souther. par. of the East China Sea, values of r.p-for.ar. should be about 100 to 400 gC/（m^2·a）. The differ.nce in the r.sults via the two methods suggests that paleopr.ductivity estimates fr.m the geological str.ta need to be made cautiously, with par.icular.attention paid to the paleogeogr.phic setting, oxic-anoxic conditions, as also the pr.ser.ation factor.of or.anic car.on.
