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,

‘Once in a lifetime’ reorganisation planned by Health Board

Published

on

THE LOCAL Health Board is embarking on a ‘once in a lifetime’ reorganisational plan which is looking at all potential options to ‘change the status quo and focus on improving health’ of locals.

This will involve, a press release has revealed, transferring more hospital services into the community where appropriate.

This is part of a strategy that the Health Board is looking into, to help solve an acute recruitment problem which is putting a great deal of pressure on the way that the Heath Board operates – and is leading to an untenable level of use of costly temporary staff to plug gaps and services.

In the summer of 2017, the Health Board embarked in an engagement with the public called ‘The Big Conversation’ which involved public workshops and drop-ins being held across the three counties of Pembrokeshire, Carmarthenshire and Ceredigion.

The Health Board now says the it has independently analysed opinions of the general public and has been using that data to explore, challenge and test different scenarios.

It is yet to be seen what these changes will mean for end service users.

The Herald understands it is likely to mean hospital services being reduced or cut, and replaced with community alternatives.

The Health Board has said it will not make any changes, unless it can guarantee the safety of the people which it serves.

The Health Board has insisted that no preferred option for change has yet been determined, and nothing has been signed off or agreed at this stage.

Medical Director Dr Philip Kloer said: “This is a once in a lifetime opportunity for our health service and community to work together to design an NHS which is fit for our generation and beyond. It has been acknowledged for some time across the UK that healthcare services are challenged like never before and we need significant change. Indeed this has been recognised in the recently published ‘Parliamentary Review of Health & Social Care’ here in Wales.

“We need to develop more proactive, resilient and better resourced local community services to support and improve people’s health and wellbeing, and avoid deterioration where possible. This will involve closer working with our partners, particularly colleagues in social care. We are also looking at ways of providing the most modern clinical practice, using the latest digital, technological, and new scientific developments, in fit for purpose facilities to provide better patient outcomes and experience.

“A number of our services are fragile and dependent on significant numbers of temporary staff, which can lead to poorer quality care. For us specifically in Hywel Dda, the geography we cover is large, with many scattered communities that are getting older, needing more holistic health and social care treatment and support. Because of this, we need to better resource our community based care, which is where most of our patient contact is, and help people manage their health conditions. We also need to evolve traditional ways of working and provide a more proactive approach. This should give patients – young, older and frail and everyone in between – the services they need when the need it, so people do not have to wait too long.

“This will mean changing hospital-based care, as well as community care, and we appreciate the attachment local people and our own staff have for their local hospitals. They have been cared for in them, or work in them, and they also play an important role in our wider communities. The options may propose change to a local hospital; however this is about more than the buildings. This is about investing in our communities, attracting doctors, nurses and therapists by operating a modern healthcare system and keeping hospitals for those who really need hospital care.

“We will not put in place any change that isn’t safe for our patients and population. And we will look at all the impacts from ensuring services are safer with better patient outcomes, to considering the wider impact on people, including the most vulnerable.”

Dr Kloer added: “The potential options are evolving, with changes to them on almost a daily basis. Many will never even reach public consultation, for a variety of reasons including safety, accessibility and affordability, or will change significantly as they are tested against population needs and healthcare standards.

“We will be coming back to the public in the spring with fewer options that have been more rigorously tested and we will open and honest about what we think our preferred option is and why. We would not, and cannot, propose something that would not be safe for our population.

“We live in this community, use our NHS and work for our NHS and we want to work with our patients, staff, partners and public to ensure it is the best it can be.”

It’s About Time

Sioned spinning

THIS January, Ceredigion Museum are proud to exhibit artwork by the portrait painter Seren Morgan Jones, originally from Aberystwyth and the third generation of women artists in her family.

Jones follows in the footsteps of her grandmother Margaret Jones, whose work forms part of the Ceredigion Museum collection. The exhibition will be followed in January 2019 by a retrospective show of work by her grandmother Margaret Jones who celebrates her 100th birthday this December.

It’s About Time is an amalgamation of two distinct bodies of work created by Seren Morgan Jones; ‘History’s Eyes’ documenting Welsh women from the 19th century and ‘Portraits of Protesters’ a collection of paintings documenting Welsh suffragists at the beginning of the twentieth century.

Drawing inspiration from historical aesthetics and references, but expanding the scope of traditional portraiture, Jones redefines and re-imagines the historical narrative, and through this creating a place for women within the Welsh visual story. The paintings take on an additional layer of importance and meaning when shown in the context of Ceredigion Museum; which houses a large collection of items representing the culture and history of the county. The collection is home to many items that have been donated by women, but we too often don’t have the narrative of those women’s lives. Jones used the Ceredigion Museum collection of welsh costume as research for her paintings depicting women in welsh traditional garb; the women largely remain nameless and faceless in our displays and yet here, in Jones’ work those women’s histories are now brought to life.

The portraits are powerful and direct; the eyes gaze unswerving to create an utterly distraction-free moment between viewer and painting which seeks to challenge and question. The portraits are imagined and shaped from stories and photographs of women rather than actual bygone figures. In the creation of these false portraits, in a style that references that of the tradition of Welsh Masters; Jones places her and the women whom she is portraying within this cultural narrative.

Of her work, Jones says: “I create an alternative image of Welsh women to counter the representation often seen in tourist shops. Some would argue that this is the only ubiquitous presence of women from Wales’ past. It is important that the viewer can relate to these women and for this they must seem to have once lived.”

Join Ceredigion Museum for the official opening of the exhibition on 27 January at 2pm. The exhibition will be opened by the renowned artist William Wilkins.

The exhibition is a partnership project with TEN gallery Cardiff and will run from 20 January until 16 April 2018 at Ceredigion Museum. For more information please contact Assistant Curator Alice Briggs, alice.briggs@ceredigion.gov.uk or 01970633086.
