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,

D-Day anniversary offer for veterans

Published

FOLLOWING the first meeting of 2019, the Ceredigion Armed Forces Community Covenant (CAFCC) wishes to endorse Royal British Legion’s generous offer of providing a fully-funded tour back to the beaches for 300 D-Day veterans.

June 6 marks the 75th anniversary of the D-Day Landings.

Following the CAFCC meeting, Councillor Paul Hinge, Ceredigion’s Armed Forces Champion said, “This most generous gesture is fantastic, everyone of those eligible to travel is a nonagenarian 90+ year old and this trip will be a fitting way to say ‘thank you’ for their contribution as the Allies won WW2.”

The Royal British Legion, in partnership with Arena Travel, have chartered a ship, the MV Boudicca, to provide a fully funded tour for 300 D-Day Veterans from 02 June until 09 June. Each veteran will be able to bring one carer who will also be fully funded.

Veterans interested in applying for the trip need to complete the eligibility form by Monday 4 February 2019. The eligibility form and more details of the event can be found online at: https://www.britishlegion.org.uk/community/d-day-75/

Sex offender caught trying to flee to Ireland

Published

A sex offender from Bow Street near Aberystwyth who tried to move to Ireland without telling anyone has been jailed.

Dennis Bull, aged 67, was caught trying to drive a van onto the Fishguard–Rosslare ferry with his belongings in the back ready for a new life in the Republic.

Bull, of Nirmit, admitted failing to comply with the conditions of registration as a sex offender and was jailed for 16 months.

Dyfed Thomas, prosecuting, told Swansea Crown Court it was the third time he had breached the order, imposed at Caernarfon crown court in February, 2016, for possessing indecent images of children.

That conviction was on top of earlier offending in New Zealand that included indecent exposure, outraging public decency and gross indecency with a child.

Mr Thomas said Bull had been jailed for 16 months in 2016 and ordered to register with the police. The restrictions imposed included a requirement to tell the police if he intended to change address.

On November 13 last year police at Fishguard harbour became aware of a Ford Mondeo registered to Bull.

A few minutes later Bull was arrested as he attempted to drive a van onto the Stenna ferry, which was loaded with household items.

Bull told the police he had made arrangements to move to Ireland “lock, stock and barrel” because he understood the monitoring of sex offenders was less strict.

In particular, said Mr Thomas, Bull did not like prospective employers being told about his convictions.

Judge Geraint Walters told Bull, “This was a planned and determined attempt to avoid detection. It was only the eagle eyes of the authorities that brought you to book.

“Your record is troubling and you present a risk of committing more offences of a sexual nature.

 “You are defiant of court orders that are there to protect others and it is truly disturbing that you are so keen to breach them.”

Bull was warned that the 2016 order remained in place for a further seven years.

Newcastle Emlyn woman to brave the shave for charity

Published

TO MARK her 50th birthday, a Newcastle Emlyn woman will brave the shave to raise money for Diabetes UK Cymru.

On January 26, Newcastle Emlyn’s Coopers Arms will be the venue where Yvonne Lloyd’s shoulder length hair will hit the deck, as it is shaved off by hairdresser Pamela Atterbury. Mayor of Newcastle Emlyn Cefin Evans will make the first cut, in an evening that will include a buffet, raffle and live music from local band Back Tracks.

Yvonne, a waitress at Ty Croeso Delicatessen, said: “My son Tristan, now 25, developed Type 1 diabetes when he was at university. However well managed, it is a life-changing condition which you can never forget.

“He was diagnosed after an emergency admission to hospital with diabetic ketoacidosis, a potentially life-threatening condition caused by extremely high blood sugar. It can be fatal if not treated immediately. He was in hospital for four days and now relies on four insulin injections a day.

“I’m having my head shaved, not just to raise money, but also to educate people. There are a lot of myths about diabetes and how it can affect your life.”

The hair cut will start at 8.30pm on Saturday January 26 at the Coopers Arms, Station Road, Newcastle Emlyn. Entry costs £5 and doors open at 7.00 pm. All are welcome.

You can support Yvonne by signing one of the sponsor forms at the Coopers Arms and Ty Croeso, or online at: https://www.justgiving.com/fundraising/yvonne-lloyd2
