Virgin birth found in wild vertebrates
First time "evolutionary novelty" found in wild animals

Researchers in the US have found a form of virgin birth in wild vertebrates for the first time, after genetically analysing pregnant females from two snake species.

They found that North American pit vipers reproduced without a male in a phenomenon called facultative parthenogenesis, previously only found in captive species, and scientists say the findings could change our understanding of animal reproduction and vertebrate evolution.

Thought to be extremely rare for normally sexual species, asexual reproduction was first identified in domestic chickens and, in recent years, reported in a few snake, shark, lizard and bird species.

However, all such "virgin births" have occurred in captivity to females kept away from males, and have in general been considered "evolutionary novelties."

Professor Warren Booth, from the University of Tulsa, Oklahoma, worked with a team to investigate virgin births in copperhead and cottonmouth female pit-vipers, where males were present.

Professor Booth, lead author of the paper published in the Royal Society's Biological Letters, said of the: "I think the frequency is what really shocked us. That's between 2.5 and 5% of litters produced in these populations may be resulting from parthenogenesis."

He added: "That's quite remarkable for something that has been considered an evolutionary novelty."

Giraffe Conservation Foundation named BVNA’s charity of the year

News Story 1
 BVNA president Wendy Nevins has named The Giraffe Conservation Foundation as the association’s charity of the year for 2017/2018.

The Giraffe Conservation Foundation dedicates its work to a sustainable future for wild giraffe populations. Wendy Nevins said: ‘I have chosen the Giraffe Conservation Foundation for the BVNA Charity of the Year because I have always thought Giraffes were magnificent animals.

‘I also think it is important that we look at the wider issue of conservation and education across all species.’

Scientists win award for openness in animal research

UK scientists have won an award for the 360ş Laboratory Animal Tours project, which offered the public an online, interactive tour of four research facilities that are usually restricted access.

The project won a public engagement award at the Understanding Animal Research (UAR) Openness Awards, which recognise UK research facilities for transparency on their use of animals in research, as well as innovation in communicating with the public.

The tour was created by the Pirbright Institute, the University of Oxford, the University of Bristol and MRC Harwell Institute.
