Humans ‘eating megafauna to extinction’ - study
Researchers said minimising the direct killing of megafauna must be a priority.
Research explores impact of human activity on largest vertebrates 

New research suggests the biggest threat facing the world’s largest vertebrates, or megafauna, is being killed for human consumption of meat or body parts.

A study led by researchers from Oregon State University found 70 per cent of megafauna species are declining, while 59 per cent are threatened with extinction. Direct harvesting for meat and body parts poses a threat to 98 per cent of these species.

Researchers looked at the impact of human activities on six classes of megafauna: mammals, ray-finned fish, cartilaginous fish, amphibians, birds and reptiles.

Writing in the journal Conservation Letters, they said: ‘Our results suggest that we are in the process of eating the world’s megafauna to extinction’.

Species are hunted for meat for human consumption or body parts to be used as trophies or in Asian traditional medicine. Other species may be targeted for feathers, leather or egg collection.

Unintentional killing is also a cause of much mortality, as animals are caught as bycatch in gill net, trawls or longlines in aquatic systems.

On average, megafauna are 2.75 times more likely to be threatened with extinction than other vertebrate species assessed by the International Union for Conservation of Nature (IUCN). In other words, seven out of 10 megafauna species will suffer further population declines in the near future, while three in five could go extinct.

Nine species became extinct between the 1760s and 2012 as a result of excessive hunting, or a combination of hunting and habitat degradation.

Researchers said minimising the direct killing of megafauna must be a priority. They recommended informing the public through educational campaigns and celebrity input to reduce demand, alongside legislation to limit collection and trade. A large group of nations must take urgent and coordinated action, they added.

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

New guidance for antibiotic use in rabbits

New best practice guidance on the responsible use of antibiotics in rabbits has been published by the BSAVA in collaboration with the Rabbit Welfare Association & Fund (RWA&F).

The guidance is free and has been produced to help veterinary practitioners select the most appropriate antibiotic for rabbits. It covers active substance, dose and route of administration all of which are crucial factors when treating rabbits owing to the risk of enterotoxaemia.

For more information and to access the guide, visit the BSAVALibrary.
