New population of blue whales discovered
The population likely spends most of it's time in the northwestern Indian Ocean, in the Arabian Sea and to the west of the Chagos.

Researchers identify group living in Indian Ocean by it's unique song

A team of researchers has found a previously unknown population of blue whales living in the Indian Ocean, after identifying an unrecognised whale song in the area.

Although blue whales are difficult to find, every population has it's own unique song, which is hugely helpful to researchers. This new song was first detected in 2017 in the Mozambique Channel off Madagascar by Dr Salvatore Cerchio, the director of the African Aquatic Conservation Fund's Cetacean Programme.

Dr Cerchio was also working with a team of scientists collecting acoustic recordings off the coast of Oman in the Arabian Sea, who also picked up the unique song.

“It was quite remarkable,” he said, “to find a whale song in your data that was completely unique, never before reported, and recognize it as a blue whale.

“With all that work on blue whale songs, to think there was a population out there that no one knew about until 2017, well, it kind of blows your mind.”

After reporting their findings to the Scientific Committee of the International Whaling Commission (IWC) in 2018, the team was contacted by Emmanuelle Leroy from the University of New South Wales, Australia, who recognised that his team had recorded the same song off the Chagos Archipelago in the central Indian Ocean.

As the collaborative team grew and analysed their shared data, they concluded that this new population likely spends most of it's time in the northwestern Indian Ocean, in the Arabian Sea and to the west of the Chagos.

The importance of this new discovering is heightened by the fact that some researchers consider both the northern Indian Ocean blue whales and Arabian Sea humpback whales to comprise unique subspecies, not simply populations, making them particularly important to biodiversity.

A published paper about the new population can be found in the journal Endangered Species Research.

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
