SCIENTISTS from the Wildlife Trust of south and west Wales’ Cardigan Bay Marine Wildlife Centre, New Quay have shown that Welsh bottlenose dolphins produce high frequency signature whistles, the highest frequency recorded for the species so far.
Bottlenose dolphins live in an aquatic environment with few physical landmarks and often poor visibility, as a result sound is very important to them.
Bottlenose dolphins are well known for their use of individually distinctive identity signals, known as signature whistles, which they use to broadcast their identity and to maintain contact with one another.
A team of researchers studying the bottlenose dolphins in Cardigan Bay, have found evidence of geographic variation in signature whistle structure, with some Welsh bottlenose dolphins whistling at higher frequencies than those found in other populations.
“We found that at least one dolphin whose signature whistle was produced at higher than expected frequencies (>30kHz), a frequency band that is outside of human hearing” says Helen Hiley, the lead author of the paper who conducted the study as part of her honours degree at St Andrews University in collaboration with researchers at Cardigan Bay Marine Wildlife Centre and the University of Western Australia.
“The use of this higher frequency for bottlenose dolphin whistle communication has not been documented elsewhere for this species, it was previously believed bottlenose dolphins did not exploit the 30-40kHz frequency band” says Hiley.
This study brings the total number of wild bottlenose dolphin populations, where signature whistles have been identified, up to six.
“The findings of this study have significant implications for the management and conservation of regional populations of dolphins, such as Cardigan Bay population.
“The reasons for the use of these higher frequencies for whistle communication are unknown and further research is required to determine the extent of the use of these ultrasonic whistles” says Sarah Perry, the Wildlife Trust of South and West Wales’ Living Seas Science Officer,
A brand new Welsh language ukulele orchestra
CAN you play the ukulele and would like to join a ukulele orchestra? Or would you like to learn a new skill and to socialise in a Welsh-speaking environment? Why not join Cerddorfa Iwcs a Hwyl?
On Monday, October 15, Cered: Menter Iaith Ceredigion, Aberystwyth Arts Centre and Learn Welsh will launch Cerddorfa Iwcs a Hwyl which is a brand new, Welsh language ukulele orchestra in Aberystwyth for free, for those aged 16+.
Cerddorfa Iwcs a Hwyl will practice weekly between 6pm and 7:30pm every Monday night during the school term and practices will take place at the Aberystwyth Arts Centre. There is no need for any experience or ability on the ukulele and there will be instruments available to borrow so that you can have a taste before buying your own ukulele.
Welsh will be the main language of Cerddorfa Iwcs a Hwyl but there is a warm welcome to everyone whatever your level of proficiency in Welsh. Cerddorfa Iwcs a Hwyl is supported by Learn Welsh as a great activity for learners to practice their Welsh outside the classroom in a fun and new way.
Cerddorfa Iwcs a Hwyl’s conductor will be Steffan Rees who has held a number of Iwcs a Hwyl workshops over the last year as Cered’s Community Development Officer. Steffan is also a musician who composes and performs as “Bwca” and he has been playing the ukulele for years.
Steffan said, “I have really wanted to start a Welsh ukulele orchestra in Ceredigion for a while having seen the successes and popularity of those in Cardiff and South East Wales. The ukulele is an instrument that excites people of all ages and with some patience and perseverance, it is an easy enough instrument to master. I’m looking forward to developing a repertoire with the orchestra and play a few gigs; the National Eisteddfod in Tregaron in 2020 perhaps!”
Numbers for the first term of the orchestra are limited so contact the Arts Centre Box Office on 01970 632 232 to book your place in Cerddorfa Iwcs a Hwyl.
Hanes Llambed meeting held
THE FIRST meeting of Hanes Llambed of the 2018/19 year was held in Lampeter’s Trinity Saint David’s Old Hall this week.
There was a good attendance as Cwrtnewydd resident Simon Evans gave the first of what will eventually be two talks about his home parish of Llanwenog.
Mr Evans spoke of how the parish was defined by the Afon Cledlyn and its tributaries, describing the region’s history from the Stone Age to the present day. The talk spoke of the several hill forts of the area, as well as Llanwenog church, founded around 500 AD, before it was built in its current form in the 14th century.
The Battle of Llanwenog in 981 AD between the Welsh and invading Danes was detailed, before the speaker went on to describe the Puritan struggle and the Civil War.
The talk then went on to the establishment of private academies by nonconformist ministers from 1750 onwards, and the founding of Unitarian chapels in the early 19th century.
The terrible agricultural situation of the 1840s was described, followed by the bad harvests, which led directly to the Rebecca Riots and emigration to the USA and elsewhere in Britain.
The next meeting of Hanes Llambed will take place in October when the subject will be the Cardiganshire War Tribunals of the First World War.
Former AM charged with child porn offences
SIMON THOMAS, the former Plaid Cymru AM for Mid & West Wales has been charged with three offences of making indecent images of children.
Mr Thomas, aged 54, was charged with the offences earlier today (Sept 18) at Aberystwyth Police Station.
He has been bailed to appear at Aberystwyth Magistrates’ Court on Wednesday, October 3.
At the time of his arrest, Mr Thomas was his Party’s spokesperson on Rural Affairs and Energy policy and had recently taken up a role which would have seen him perform a significant role in Plaid Cymru’s future campaigns.
His arrest in July was a shock both to his political allies and those in other parties in the Assembly.
Following his arrest, Mr Thomas resigned immediately as an Assembly Member and from Plaid Cymru. He was replaced as regional AM by Helen Mary Jones.
