Gan ategu safbwyntiau aelodau eraill o'r Is-adran Organebau a'r Amgylchedd, mae fy ngwaith yn benodol ecolegol ac wedi'i unedig gan y thema o bersbectif ar raddfa ecosystem afonydd, llynnoedd a gwlyptiroedd. Mae'r gweithgareddau yn canolbwyntio ar:
- Effeithiau newid byd-eang ar organebau ac ecosystemau dŵr croyw
- Bioamrywiaeth dŵr croyw
- Ecoleg adar afonydd a gwlyptir
Mae atebion i broblemau ecosystemau dŵr croyw trwy bolisi a rheoli hefyd yn ffocws pwysig, ac rwy'n cynorthwyo cyfarwyddwr Sefydliad Ymchwil Dŵr y Brifysgol ar ôl bod yn allweddol wrth ei ffurfio. Rwyf hefyd yn ymwneud â chymhwyso ecoleg fel Is-lywydd yr RSPB (elusen bywyd gwyllt fwyaf Ewrop), Cadeirydd Annibynnol Fforwm Afancod Fforwm Cymru, ac yn ddiweddar cwblhau tymor 7.5 mlynedd fel Dirprwy Gadeirydd Cyfoeth Naturiol Cymru (y corff mwyaf a noddir gan Lywodraeth Cymru) ac fel aelod o Gyd-bwyllgor Cadwraeth Natur y DU . Mae ei rolau presennol hefyd yn cynnwys aelodaeth o'r Panel Cynghori Arbenigol Nodiadau Banc Lloegr - cynghori ar y defnydd o ddelweddau bywyd gwyllt ar nodiadau banc y DU.
Mae pob un o'r themâu hyn yn cael ei ehangu o dan 'Ymchwil', tra bod fy ymwneud helaeth â chyrff anllywodraethol, cyrff proffesiynol, busnesau a sefydliadau'r llywodraeth wedi'i amlinellu o dan 'Bywgraffiad'.

Ymchwil
Deuthum i Gaerdydd ym 1980 ar gyfer MSc mawreddog UWIST mewn Hydrobioleg Gymhwysol, ac oddi yno cwblhau PhD ar ansawdd dŵr ac infertebratau yng nghysawd afon Gwy. Ar yr un pryd, datblygais ddiddordeb mewn ecoleg adar afon, gan ddangos am y tro cyntaf sut yr effeithiwyd ar y grŵp hwn gan law asid. Mae'r prif themâu hyn - pwysau lluosog ar raddfa fyd-eang ar ecosystemau dŵr croyw, infertebratau afonydd ac adar mewn cynefinoedd dyfrol - wedi parhau i ddarparu fy modelau ymchwil mawr.
O 1984 ymlaen, arweiniais grŵp ôl-ddoethurol yn ymchwilio i effeithiau ecolegol asideiddio mewn afonydd ucheldirol gan ddefnyddio arolygon, modelau ac arbrofion ar raddfa ecosystemau yn Arsyllfa Llyn Brianne. Mae'r arbrofion hyn bellach wedi rhedeg ers bron i 40 mlynedd, ac mae fy ngwaith ar raddfa ecosystem wedi ehangu i gwmpasu effeithiau newid byd-eang ar ecosystemau dyfroedd croyw ar dri chyfandir. Mae'r gwaith diweddaraf gydag ystod eang o gydweithwyr yn parhau i ehangu ein tystiolaeth am sensitifrwydd dyfroedd rhedeg i newid yn yr hinsawdd tra hefyd yn adrodd y stori ryfeddol o sut mae adferiad afonydd Prydain o broblemau glanweithdra gros wedi cael ei dymheru gan yr her gynyddol o lygredd gwasgaredig o ffynonellau trefol a gwledig.
Hyd yn hyn, mae fy nghyfanswm gyrfa o dros 330 o gyhoeddiadau gwyddonol wedi cael eu dyfynnu dros 32,000 o weithiau yn H > 87 (Google Scholar).
Meysydd ymchwil
Effeithiau newid byd-eang ar organebau ac ecosystemau dŵr croyw
Am bron i bedwar degawd, mae themâu amlwg yn fy ngwaith wedi bod yn effeithiau hirdymor ar raddfa fawr o newid byd-eang ar ecosystemau dŵr croyw yn ogystal ag adferiad ecosystemau lle mae straen lluosog wedi'u rheoli neu eu dileu (gweler 'Cyhoeddiadau')
Mae gan ein Arsyllfa Llyn Brianne Stream unigryw yn fyd-eang, sy'n weithredol o 1981, nifer o ffrydiau arbrofol a chyfeirio sydd wedi bod yn amlwg wrth ddeall effeithiau newid byd-eang ar ecosystemau dŵr croyw. Mae'r safle hefyd yn gyfres o sianeli arbrofol replicate, rhaeadru sy'n ffigur fwyfwy mewn gwaith ymchwil.
Bioamrywiaeth Dŵr Croyw
Mae bioamrywiaeth afonydd a gwasanaethau ecosystemau wedi dod yn ffocws cynyddol bwysig yn fy ngwaith, yn enwedig i ddeall sut mae bioamrywiaeth yn cefnogi gwasanaethau a sut mae straen amgylcheddol yn erydu swyddogaethau ecosystemau a darparu gwasanaethau.
Mae enghreifftiau'n cynnwys:
- Cyd-arweinyddiaeth adrannau dŵr croyw y http://uknea.unep-wcmc.org/ Asesu Ecosystemau Cenedlaethol ar gyfer Defra a'r Gweinyddiaethau Datganoledig (Maltby & Ormerod 2011 http://uknea.unep-wcmc.org/Resources/tabid/82/Default.aspx )
- Gweithredu fel PI Caerdydd ym mhrosiect NERC BESS gwerth £3.1 miliwn, Duress http://nerc-duress.org/ (Amrywiaeth mewn Afonydd yr Ucheldir ar gyfer Cynaliadwyedd Gwasanaethau Ecosystemau; o 2012 ymlaen)
- Gweithredu fel PI Caerdydd a chyd-arweinydd astudiaethau dalgylch ym mhrosiect MARS a ariennir gan yr UE gwerth €9 miliwn (Rheoli ecosystemau dyfrol ac adnoddau dŵr o dan straen lluosog; o 2014 ymlaen)
Mae fy ngwaith bioamrywiaeth hefyd yn cynnwys ffocws sylweddol ar lygredd
Arweiniodd diddordeb hirsefydlog yn effeithiau llygredd ar dŵr croyw - gan gynnwys glaw asid, dŵr gwastraff a sylweddau senobiotig - yn 2016 at rai o'r asesiadau cyntaf yn y byd o ficroplastigau mewn gweoedd bwyd afonydd. Datgelodd ymchwiliad i Afon Gwy, Brynbuga a Taf fod tua 50% o bryfed yn cynnwys ffibrau plastig (Windsor et al. 2019) . Ers hynny mae gwaith pellach wedi dangos sut mae'r deunydd hwn yn cael ei drosglwyddo i ysglyfaethwyr afonydd (D'Souza et al. 2020_, hefyd asesu ei ffynonellau, ei fflwcs, ei dynged a'i effeithiau yn amgylchedd yr afon. Mae'r gwaith cyfredol hefyd yn cynnwys asesiadau o gyfansoddion fferyllol dynol a milfeddygol mewn afonydd.
Ecoleg adar afonydd a gwlyptir
Dechreuais ymddiddori mewn adar afonydd, ac yn arbennig dippers, wrth ymchwilio i infertebratau dyfrol ar gyfer fy PhD. Arweiniodd y diddordeb hwn at rai o'r dystiolaeth gyntaf yn y byd y gallai glaw asid effeithio ar adar (e.e. Ormerod et al. 1991), ac yn ei dro rhai o ymchwil adar awtecolegol mwyaf adnabyddus y byd. Arweiniodd y cysyniad o ddefnyddio dippers fel dangosyddion asidedd at ymchwil i'w rôl fel dangosyddion agweddau ehangach o ansawdd dŵr sydd ar hyn o bryd yn cynnwys halogion etifeddiaeth neu sy'n dod i'r amlwg, llygredd gwasgaredig a microplastigau. Yn ddiweddar, cydweithiais â Sefydliad Bywyd Gwyllt India mewn ymchwiliadau i effeithiau newid byd-eang ar afonydd Himalaya – lle mae'r casgliad mwyaf amrywiol o adar afon ar y Ddaear yn meddiannu un o'i ranbarthau sy'n newid gyflymaf.
