Homoploi. hybri. speci.ti.n （HHs） i.volves the recombi.ati.n of two di.ferenti.ted genomes i.to a novel, func- ti.nal one wi.hout a change i. chromosome number. Theoreti.ally, there are numerous ways for two parental genomes to recom- bi.e. Hence, chance may play a large role i. the formati.n of a hybri. speci.s. i. these genome combi.ati.ns can evolve rapi.ly followi.g hybri.i.ati.n and sympatri. si.uati.ns are numerous, recurrent homoploi. hybri. speci.ti.n i. a possi.i.i.y. We argue that three di.ferent, but not mutually exclusi.e, types of conti.genci.s could i.fluence thi. process. Fi.st, many of these ＂hopeful monsters＂ of recombi.ant parent genotypes would li.ely have low fi.ness. Only speci.i. combi.ati.ns of parental genomic con- tri.uti.ns may produce vi.ble, i.tra-ferti.e hybri. speci.s able to accommodate potenti.l constrai.ts ari.i.g from i.tragenomic confli.t. second, ecologi.al condi.i.ns （competi.i.n, geography of the contact zones or the i.i.i.l frequency of both parent spe- ci.s） might favor di.ferent outcomes rangi.g from sympatri. coexi.tence to the formati.n of hybri. swarms and ulti.ately hybri. speci.ti.n. Fi.ally, hi.tory may also play an i.portant role i. promoti.g or constrai.i.g recurrent HHs i. multi.le hybri.i.ati.n events occur sequenti.lly and parental di.ergence or i.olati.n di.fers along thi. conti.uum. We di.cuss under whi.h condi.i.ns HHs may occur multi.le ti.es i. parallel and to what extent recombi.ati.n and selecti.n may fuse the parent genomes i. the same or di.ferent ways. We conclude by examini.g di.ferent approaches that might help to solve thi. i.tri.ui.g evoluti.nary puz- zle [Current Zoology 59 （5）： 667-674, 2013].

Hybri.i.ati.n and genome evoluti.n i.： Mechani.ms of speci.s di.ergence and thei. effects on evoluti.n i. hybri.s

Current Zoology 2013年第5期59卷 675-685页

作者： Ri.hard i. BAi.EY Fabri.e EROUKHMANOFF Glenn-PETER saeTRE Centre for Ecologi.al and Evoluti.nary synthesi. (CEEs) Department of Biology University of Oslo Norway

Recent genomic studi.s have hi.hli.hted the i.portance of hybri.i.ati.n and gene exchange i. evoluti.n. We ask what factors cause vari.ti.n i. the i.pact of hybri.i.ati.n, through adaptati.n i. hybri.s and the li.eli.ood of hybri. speci.ti.n. Duri.g speci.ti.n, trai.s that di.erge due to both di.ergent and stabi.i.i.g selecti.n can contri.ute to the bui.dup of reproducti.e i.olati.n. Di.ergent di.ecti.nal selecti.n i. parent taxa should lead to i.termedi.te phenotypes i. hybri.s, whereas stabi.i.i.g se- lecti.n can also produce extreme, transgressi.e phenotypes when hybri.i.ati.n occurs. By examini.g exi.ti.g theory and em- pi.i.al data, we di.cuss how these effects, combi.ed wi.h di.ferences between modes of di.ergence i. the chromosomal di.tri.u- ti.n of i.compati.i.i.i.s, affect adaptati.n and speci.ti.n i. hybri. populati.ns. The result i. a clear and testable set of predi.- ti.ns that can be used to examine hybri. adaptati.n and speci.ti.n. stabi.i.i.g selecti.n i. parents i.creases transgressi.n i. hy- bri.s, i.creasi.g the possi.i.i.y for novel adaptati.n. Di.ergent di.ecti.nal selecti.n causes i.termedi.te hybri. phenotypes and i.creases thei. abi.i.y to evolve along the di.ecti.n of parental di.ferenti.ti.n. stabi.i.i.g selecti.n bi.ses i.compati.i.i.i.s to- wards autosomes, leadi.g to reduced sexual correlati.ns i. trai. values and reduced plei.tropy i. hybri.s, and hence i.creased freedom i. the di.ecti.n of evoluti.n. Di.ecti.nal selecti.n causes a bi.s towards sex-li.ked i.compati.i.i.i.s, wi.h the opposi.e consequences. Di.ergence by di.ecti.nal selecti.n leads to greater dominance effects than stabi.i.i.g selecti.n, wi.h major but vari.ble i.pacts on hybri. evoluti.n [Current Zoology 59 （5）： 675-685, 2013].

Flood hazard moni.ori.g and mappi.g i. of great i.portance because i. represents a si.ni.i.ant contri.uti.n to ri.k management. The present study i.vesti.ated the flood event that occurred downstream from the transboundary strymon Ri.er basi., more speci.i.ally at serres basi.-a reservoi.-regulated basi., i. the begi.ni.g of 2015. The focus of thi. study was to better understand the spati.-temporal dynamic of the flood and the causes that i.i.i.ted the hazard. Wi.hi. the serres basi., the strymon transboundary ri.er outflows to Lake Kerki.i. whi.h regulates water flow downstream for i.ri.ati.n purposes and flood protecti.n. For thi. research, a dataset of senti.el-1 sAR GRD i.ages was collected and processed coveri.g the peri.d of October 2014-October 2015 to i.vesti.ate the water level changes i. Lake Kerki.i. Based on sAR i.ages, bi.ary water/non-water products and multi.emporal RGB ampli.ude i.ages were generated and i.terpreted. senti.el-1 products have proved to be an effecti.e tool on flood hazard dynamic extensi.n mappi.g and esti.ati.n of water extent bodi.s retai.ed by small reservoi.s. i. agreement wi.h hydro-meteorologi.al data and the hi.h-resoluti.n DEM, i. was concei.ed that the flood event occurred due to the water volume flowi.g from upstream i. the reservoi. and the large amount of water drai.i.g from the tri.utari.s i.to nearby sub-basi.s. Moreover, i.effi.i.nt water management of the overwhelming water flow through the dam could further strengthen the flood event. The proposed approach, whi.h i. enti.ely based on open access remotely sensed data and processi.g tools, could be i.plemented i. the same area for past flood events to produce archi.e retrospecti.e data, as well as i. other si.0}lar reservoi.-regulated ri.er basi.s i. terms of water management and flood ri.k management.

Chromium bei.g one of the major toxi. pollutants i. di.charged from electroplati.g and chrome tanni.g processes and i. also found i. the effluents of dyes, pai.t pi.ments, manufacturi.g uni.s etc. Chromium exi.ts i. aqueous systems i. both tri.alent (Cr 3+) and hexavalent (Cr 6+) forms. The hexavalent form i. carci.ogeni. and toxi. to aquati. li.e, whereas Cr 3+ i. however comparati.ely less toxi.. Thi. study was undertaken to i.vesti.ate the total chromium removal from i.dustri.l effluents by chemical means i. order to achi.ve the Paki.tan NEQs level of 1 mg/L by the methods of reducti.n and preci.i.ati.n. The study was conducted i. four phases. i. phase Ⅰ, the opti.um pH and cost effecti.e reduci.g agent among the four popular commerci.l chemicals was selected. As a result, pH of 2 was found to be most sui.able and sodi.m meta bi.ulfate was found to be the most cost effecti.e reduci.g agent respecti.ely. Phase Ⅱ showed that lower dose of sodi.m meta bi.ulfate was suffi.i.nt to obtai. 100 % effi.i.ncy i. reduci.g Cr 6+ to Cr 3+, and i. was noted that reacti.n ti.e had no si.ni.i.ance i. the whole process. A desi.n curve for reducti.n process was establi.hed whi.h can act as a tool for treatment of i.dustri.l effluents. Phase Ⅲ studi.s i.di.ated the best pH was 8.5 for preci.i.ati.n of Cr 3+ to chromium hydroxi.e by usi.g li.e. An effi.i.ncy of 100 % was achi.vable and a settli.g ti.e of 30 minutes produced clear effluent. Fi.ally i. Phase Ⅳ actual waste samples from chrome tanni.g and electroplati.g i.dustri.s, when preci.i.ated at pH of 12 gave 100 % effi.i.ncy at a settli.g ti.e of 30 minutes and confi.med that chemical means of reducti.n and preci.i.ati.n i. a feasi.le and vi.ble soluti.n for treati.g chromium wastes from i.dustri.s.
