Renewed Hope? Katie Mortimer-Jones, 2 Mai 2014 The nest of Peregrine falcons in the clock tower appears to have failed, due to unknown causes sometime during the last week or so. However, after an absence of several days, both birds are showing renewed interest in the nest-site. Today has seen considerable activity with one bird visiting the nest several times and apparently busying itself tidying the interior while the other bird of the pair watched from close by. Although peregrines only have one brood each year, if the first brood is lost at an early stage they sometimes re-lay a second clutch, either in the original nest, or perhaps more often, at a nearby site. We now watch, wait and hope that a new clutch of eggs will be laid sometime in the near future and that these magnificent falcons will have more success the second time around.Adrian Plant
Breeding failure Katie Mortimer-Jones, 30 Ebrill 2014 It now looks that the breeding attempt by Peregrine Falcons in the clock tower has failed. All indications were that eggs were laid during late March and early April and if all had gone according to plan, they should have been hatching about now (eggs are usually incubated for 31-33 days). Unfortunately, no birds have been seen at the nest or perched nearby on the clock tower for several days now so it seems certain that the nest has been abandoned. We do not know why this breeding attempt has failed but the most likely cause is that the eggs have been eaten by predators, perhaps crows, ravens or gulls. Although peregrines only raise one brood each year it remains possible that the birds will make a second attempt to breed and we remain vigilant in case that happens.Adrian Plant

Exploring biodiversity in the Amazon Adrian Plant, 15 Ebrill 2014 Adrian Plant continues his fieldwork in the Amazon in collaboration with Jose Albertino Rafael and Josenir Camara from INPA (Brazil’s national Amazon research organisation) in Manaus.So far two field-trips to remote corners of the Amazon have been successfully completed. The first was to Sao Gabriel da Cachoeira high up the Rio Negra not far from Brazil’s borders with Colombia and Venezuela and the second to a major tributary of the Amazon along the border with Peru at Benjamin Constant.The forests of the Amazon Basin are flood forests; they become seasonally inundated by the flooded river and the waters bring with them many of the nutrients essential to the forests great productivity throughout the region. This year the forest remains unusually wet for the time of year which has caused a few practical problems for field entomology.- it is an acquired pleasure to slosh around in deep mud and water searching for new and interesting insects under a constant plague of biting mosquitoes. Yet, to an entomologist this is more or less a definition of “fun”!The biodiversity is amazing of course and many of the insects seen and collected are undoubtedly new to science but will require much study in more comfortable surroundings after returning from the field. Meanwhile, Adrian will shortly be setting out on a third fieldtrip, this time to a little known area between the mouth of the Amazon river and French Guiana where many exciting discoveries will undeniably be made.
Llwch Llundain Catalena Angele, 14 Ebrill 2014 Os oeddech chi yn ymweld â Llundain yr wythnos diwethaf mae’n siŵr eich bod chi wedi sylwi bod yr awyr yn llawn llwch – fel edrych drwy gwmwl brwnt! Ond beth yw mwrllwch, a beth yw’r gwahaniaeth rhyngddo â niwl?Beth yw niwl?Cwmwl ar y llawr yw niwl! Llawer o ddiferion dŵr mân yn hofran yn yr awyr yw niwl ac mae’n rhan naturiol o’r tywydd. Mae niwl yn helpu i ddyfrio planhigion ac yn ddiogel i chi ei anadlu i mewn.Beth yw mwrllwch?Llygredd aer yw mwrllwch. Mae’n cael ei gynhyrchu wrth i niwl gymysgu â mwg a nwyon cemegol ceir a ffatrïoedd ac mae rhai o’r cemegau yma’n wenwynig! Mae’n niweidio planhigion ac anifeiliaid a gall fod yn beryglus ei anadlu i mewn.Mae’r mwrllwch diweddar yn Llundain yn gymysgedd o niwl, llygredd a thrydydd cynhwysyn – tywod o’r Sahara! Anialwch anferth yn Affrica yw’r Sahara ac mae peth o’r tywod yno yn fân iawn, iawn fel llwch. Weithiau bydd stormydd gwynt yn codi’r llwch a’i chwythu filoedd o filltiroedd i’r DU. Dyna siwrnai hir!Yn anffodus, mae’r gymysgedd o niwl, llygredd a llwch yr anialwch yn golygu bod mwrllwch Llundain yn niweidio’r ysgyfaint, ac mae wedi gwneud rhai pobl yn sâl. Mae mwrllwch yn un rheswm da iawn pam y dylen ni i gyd geisio lleihau llygredd aer!Beth alla i ei wneud i leihau llygredd aer?Meddyliwch am lygredd aer… beth sy’n ei achosi? Allwch chi feddwl am 3 pheth y gallech chi ei wneud i leihau llygredd aer? Trafodwch yn y dosbarth cyn gwirio eich atebion yma (gwefan Saesneg). Dilynwch y ddolen hon i ddysgu mwy am fwrllwch. Dilynwch y ddolen hon. Eich cwestiynau, fy atebion: Glyncollen Primary School: Sorry we were late again. We had a busy week as we are going to Llangrannog. We have had great fun doing this investigation. We can't wait to find out who has won the competition. We are going to tell the year3 class about it as they will be doing it next year. Thank you Professor Plant. Yr. 4. Prof P: Hope you had fun at Llangrannog! I am so glad you have enjoyed the investigation Glyncollen. Thank you so much for taking part! Ysgol Clocaenog: Pen wedi disgyn ffwrdd! Athro'r Ardd: Wedi colli ei ben! Gladestry C.I.W. School: Although the flowers were open earlier in the week, they have closed up again at the drop in temperature. Prof P: I can tell that you have learnt a lot about your planrs Gladestry, well done! Diolch yn fawr Athro'r Ardd
