Trosolwyg
Rwy'n Ecolegydd Planhigion Trofannol sy'n canolbwyntio ar ddeall sut mae planhigion a dŵr yn gyrru ecoleg, esblygiad a swyddogaeth amgylcheddau trofannol. Mae fy ngwaith wedi'i adeiladu ar ddealltwriaeth fanwl o ecoffisioleg planhigion a datblygu technolegau synhwyrydd newydd, gan fy ngalluogi i astudio sut mae planhigion yn siapio ein planed.
Ddaear - Planhigion Planed
Pe baech chi'n gosod dail pob planhigyn ochr yn ochr, byddent yn gorchuddio wyneb y Ddaear. Ac o dan bob un o'r dail hynny byddai cannoedd o gwndidau microsgopig yn eu cefnogi'n fecanyddol, gan eu cadw wedi'u hydradu a'u cyflenwi â maetholion. Mae'r cwndidau hynny'n ffurfio system cludo dŵr planhigion ac yn gosod y terfynau y gall planhigion weithredu ynddynt ac, o ganlyniad, yn gyrru eu ecoleg, eu esblygiad a'u hymatebion i newid yn yr hinsawdd.
System Cludo Dŵr Planhigion
Esblygiad system cludo dŵr planhigion (h.y. eu system hydrolig) oedd y digwyddiad esblygiadol pwysicaf yn y 550 miliwn o flynyddoedd diwethaf. Mae'r system hydrolig planhigion yn 60% o'r holl biomas byw ac yn dychwelyd 70% o'r holl law yn ôl i'r atmosffer. Newidiodd ei esblygiad bob un broses geomorffolegol, biocemegol a hinsoddol ar y blaned. Sut mae system cludo dŵr planhigion trofannol yn modiwleiddio y prosesau hynny, o nano-ffisioleg i ecoleg ecosystemau a biogeocemeg ar raddfa fawr, yw ffocws fy astudiaethau.
Arbrofion Trofannol ar Raddfa Fawr
Arbrawf Ffrwythloni CO2 aer am ddim Amazon (AmazonFACE, chwith) ac Arbrawf Gwahardd Trwy'r Caxiuanã (eSecaFlor, dde).
Y system cludo dŵr yw nod canolog swyddogaeth coeden. Mae'n nid yn unig yn pennu eu sensitifrwydd sychder ond yn gosod y ffiniau ar gyfer swyddogaeth canopi a gwrthsefyll biomecanyddol wrth ddal y rhan fwyaf o faetholion y goeden. Rwyf wedi bod yn arwain gwaith allweddol yn rhai o'r arbrofion trofannol mwyaf i ddeall sut mae ymatebion coed trofannol i newidiadau mewn argaeledd dŵr, CO2 a maetholion yn cael eu modiwleiddio gan eu system cludo dŵr.
Coedwigoedd Trofannol Enfawr
Dringwr coed ar ben coeden Dinizia excelsa 70m o uchder (chwith) a synwyryddion twf dendrometrig yn cael eu gosod yn ei boncyff (dde).
Rwyf hefyd yn gweithio gyda choedwigoedd trofannol enfawr. Mae gan yr ecosystemau anhygoel hynny ddwysedd uchel o goed mawr, rhai dros 80 m o uchder, sy'n dal symiau enfawr o biomas a bioamrywiaeth unigryw ac sydd heb ei archwilio o hyd. Mae'r coed enfawr hyn yn 1% o'r holl goed trofannol ond maent yn storio >50% o garbon uwchben y ddaear ac rhagwelir y byddant yn wynebu risg gynyddol o farwolaethau a achosir gan sychder, gyda goblygiadau mawr i storfeydd carbon daearol y Ddaear. Nid yw'r coedwigoedd enfawr hynny'n digwydd ar hap ar draws y trofannau ond mewn lleoliadau penodol iawn ym mhob cyfandir. Pam maen nhw'n digwydd lle maen nhw'n digwydd, pwy yw'r coed enfawr hynny, sut maen nhw'n gweithredu ac yn cludo dŵr a pha mor sensitif ydyn nhw i newid yn yr hinsawdd i gyd yn gwestiynau rwy'n ceisio eu hateb.
Deall rhyngweithiadau cymhleth
Goedwigoedd trofannol oedi trothwyon newid hinsawdd critigol o 20+ mlynedd. Gydag effeithiau newid yn yr hinsawdd yn costio dros 1.5 triliwn o ddoleri bob blwyddyn, mae gwybod yn union faint o amser y gall coedwigoedd trofannol ei brynu i ni yn frys. Fodd bynnag, mae modelau presennol yn methu â rhagweld tynged coedwigoedd trofannol. Mae hyn oherwydd y ddealltwriaeth fecanyddol sylfaenol o swyddogaeth coed sy'n deillio o astudiaethau sy'n canolbwyntio ar ffactorau cyfyngol unigol tra bod y gwir yw bod straen lluosog yn rhyngweithio i gyd-gyfyngu ar swyddogaeth coed ar yr un pryd. Er mwyn deall tynged coedwigoedd trofannol, mae angen i ni ddeall sut mae ffactorau biotig (ontogeny, maint, ffylogeni, plastigrwydd) ac abiotig (gwynt, ffrwythlondeb, golau, dŵr, CO2, tymheredd) a straen yn rhyngweithio ac yn cyd-gyfyngu ar swyddogaeth coedwigoedd trofannol.
Y Genhedlaeth Nesaf o Dechnoleg ar gyfer Ecoleg Drofannol
Gweithio yn y maes
Parc Cenedlaethol Mynyddoedd Tumucumaque, Dirgelion Coed Amazonaidd enfawr, llun gan Leonardo Chaves – Revista Fapesp
Rwy'n arbennig o angerddol am waith maes a'r gwerth aruthrol y mae'n ei gynnig. Mae gwaith maes trofannol yn dod â phrofiad trawsddiwylliannol unigryw at ei gilydd sy'n ein galluogi i ddeall yn well sut mae gweithio gyda'i gilydd ag actorion o gefndiroedd amrywiol yn sylfaenol ar gyfer byd gwell. Cysylltu a chryfhau'r grwpiau lluosog hynny, o gymunedau afonol, myfyrwyr, academyddion, arloeswyr a gwneuthurwyr penderfyniadau, yw fy hoff ran o'r swydd hon.
