Arsen.c （As） is a pervasive en.iron.en.al toxin.an. carcin.gen.c metalloid. It ran.s at the top of the US priority List of Hazardous Substan.es an. causes worldwide human.health problems. Wetlan.s, in.ludin. n.tural an. artificial ecosystems （i.e. paddy soils） are highly susceptible to As en.ichmen.; actin. n.t on.y as repositories for water but a host of other elemen.al/chemical moieties. While macroscale processes （physical an. geological） supply As to wetlan.s, it is the micro-scale biogeochemistry that regulates the fluxes of As an. other trace elemen.s from the semi-terrestrial to n.ighborin. plan./ aquatic/atmospheric compartmen.s. Amon. these fin.-scale even.s, microbial mediated As biotran.formation. con.ribute most to the elemen.＇s chan.in. forms, actin. as the ＇switch＇ in.defin.n. a wetlan. as either a source or sin. of As. Much of our un.erstan.in. of these importan. microbial catalyzed reaction. follows relatively recen. scien.ific discoveries. Here we documen. some of these key advan.es, with focuses on.the implication. that wetlan.s an. their microbial mediated tran.formation.pathways have on.the global As cycle, the chemistries of microbial mediated As oxidation. reduction.an. methylation. an. future research priorities areas.

Elemen. profile was in.estigated for their use to trace the geographical origin.of rice （Oryza sativa L.） samples. The con.en.ration. of 13 elemen.s （calcium （Ca）, potassium （K）, magn.sium （Mg）, phosphorus （P）, boron.（B）, man.an.se （Mn., iron.（Fe）, n.ckel （n.）, copper （Cu）, arsen.c （As）, selen.um （Se）, molybden.m （Mo）, an. cadmium （Cd）） were determin.d in.the rice samples by in.uctively coupled plasma optical emission.an. mass spectrometry. Most of the essen.ial elemen.s for human.health in.rice were within.n.rmal ran.es except for Mo an. Se. Mo con.en.ration. were twice as high as those in.rice from Vietn.m an. Spain. Mean.hile, Se con.en.ration. were three times lower in.the whole provin.e compared to the Chin.se average level of 0.088 mg/kg. About 12% of the rice samples failed the Chin.se n.tion.l food safety stan.ard of 0.2 mg/kg for Cd. Combin.d with the multi-elemen.al profile in.rice, the prin.ipal compon.n. an.lysis （PCA）, discrimin.n. fun.tion.an.lysis （DFA） an. Fibon.cci in.ex an.lysis （FIA） were applied to discrimin.te geographical origin. of the samples. Results in.icated that the FIA method could achieve a more effective geographical origin.classification.compared with PCA an. DFA, due to its efficien.y in.makin. the groupin. even.when.the elemen.al variability was so high that PCA an. DFA showed little discrimin.tory power. Furthermore, some elemen.s were iden.ified as the most powerful in.icators of geographical origin. Ca, n., Fe an. Cd. This suggests that the n.wly established methodology of FIA based on.the ion.me profile can.be applied to determin. the geographical origin.of rice.

Because of its importan.e as a food source, n.mipterus japon.cus （Bloch, 1791）（n.mipteridae） or Japan.se threadfin.bream is the best studied of these taxa, an. n.merous in.estigation. have examin.d its fisheries, its biology an. biochemistry. De- spite such in.en.ive work, the taxon.mic status of n. japon.cus has n.ver been.seriously question.d an. it is regarded as a common.species, widely distributed throughout the In.o-Westem Pacific Ocean. In.fact, Bloch＇s description.of the type specimen.of ***- pon.cus has ambiguous collection.data an. lacks a design.tion.for the type locality, though it is probably Java. In.this paper, Dn. barcode results based on.COl gen. support the existen.e of two geographically separated lin.ages of the Japan.se threadfin.bream, both bein. an.In.ian.Ocean.an. western.Pacific lin.age, with 2.7% sequen.e divergen.e, an. the results in.icate a possible existin. of some cryptic species. The two lin.ages also possess a diagn.stic differen.e in.their belly color, with specimen. in.the South Chin. Sea havin. a silver belly, while those from the In.ian.Ocean.isolate specimen.have a yellow coloration. Based upon.n.w collection. from the South Chin. Sea, this species from the western.Pacific is morphologically redescribed an. its details of Dn. barcode diver- sity are shown.for the future in.estigation..

We report the miscibility characteristics of two compon.n.s in.a bin.ry mixture of 9-phen.l an.hracen. （PA） mixed with stearic acid （SA） or polymethyl methacrylate （PMMA）. The behaviour of surface pressure versus area per molecule isotherms reveal that the area per molecule decreases systematically with in.reasin. molefraction. of PA. The characteristics of areas per molecule versus molefraction. an. collapse pressure vs molefraction.in.icate that various in.eraction. in.olved amon. the sample an. matrix molecules. The in.eraction.scheme is foun. to chan.e with the chan.e in.surface pressure an. molefraction.of mixin.. Scan.in. electron.microscopic study con.irms the aggregation.of PA molecules in.the mixed films.

The tomen.ose cochin.al scale in.ect, Dactylopius tomen.osus （Lamarck）（Hemiptera： Dactylopiidae）, is an.importan. biological con.rol agen. again.t in.asive species of Cylin.ropun.ia （Caryophyllales： Cactaceae）. Recen. studies have demon.trated that this scale is composed of host-affiliated biotypes with differen.ial host specificity an. fitn.ss on.particular host species. We in.estigated gen.tic variation.an. phylogen.tic rela-tion.hips amon. D. tomen.osus biotypes an. proven.n.es to examin. the possibility that gen.tic diversity may be related to their host-use pattern. an. whether their phylogen.tic relation.hips would give in.ights in.o taxon.mic relatedn.ss of their host plan.s. n.cleotide sequen.e comparison.was accomplished usin. sequen.es of the mitochon.rial cytochrome c oxidase I （COI） gen.. Sequen.es of in.ividuals from the same host plan. within.a region.were iden.ical an. characterized by a un.que haplotype. In.ividuals belon.in. to the same biotype but from differen. region. had similar haplotypes. However, haplotypes were n.t shared between.differen. biotypes. Phylogen.tic an.lysis grouped the mon.phyletic D. tomen.osus in.o 3 well-resolved clades of biotypes. The phylogen.tic relation.hips an. clusterin. of biotypes correspon.ed with kn.wn.taxon.mic relatedn.ss of their hosts. Two biotypes, Fulgida an. Mamillata, tested positive for Wolbachia （α-Proteobacteria）, a common.en.osymbion. of in.ects. The Wolbachia sequen.es were seren.ipitously detected by usin. in.ect-specific COI Dn. barcodin. primers an. are most similar to Wolbachia Supergroup F strain.. This study is the first molecular characterization.of cochin.al biotypes that, together with Wolbachia sequen.es, con.ribute to the better iden.ification.of the biotypes of cochin.al in.ects an. to the biological con.rol of cacti usin. host-specific biotypes of the scale.
