57 Snow Monkeys Euthanized for Carrying 'Alien' Genes

The Takagoyama Nature Zoo in the city of Futtsu, Japan euthanized 57 snow monkeys who were found to have hybrid genetic make-ups. The zoo mistakenly believed all 164 of its resident primates were pure Japanese macaques (Macaca fuscata), which are endemic to Japan. When the zoo discovered through DNA testing that 57 of them were actually of a hybrid breed, rhesus macaque (Macaca mulatta), which is common throughout Southeast Asia, they culled the hybrid monkeys.

In 2013, Japan's environmental laws were revised to make holding or transporting invasive species including hybrids illegal, in an attempt to protect the indigenous environment and native species. Culling of rhesus macaque is allowed under this law, which designates them as an "invasive alien species."

An Office for Alien Species Management official said the culling was unavoidable because the hybrid species might escape and reproduce in the wild, BBC reported.

The monkeys were culled through lethal injection over the course of about a month, ending in early February. The zoo operator then held a memorial service for the hybrid monkeys at a local Buddhist temple.

Questions remain as to whether other steps could have been taken such as sterilization, IFL Science pointed out. Transplanting the common hybrids into another region may have also been a possibility; they are native to Burma, India, Thailand, Afghanistan, Vietnam, Bangladesh, Pakistan, Nepal and China.

"There are many zoos in the country, which rear animals that became classified as invasive species after the law was created," an Environment Ministry official said, according to Phys.org. Zoos can apply for exceptions to keep the hybrid species.

"Preventing exposures to foreign animals is very important," said Tomoko Shimura of the Nature Conservation Society of Japan. The Chiba prefecture where the zoo is located has been culling the hybrids since 2005.

Japanese macaques are brown with white faces and are the only indigenous primate in Japan and most northern living nonhuman primate on Earth. They are also known as snow monkeys and have developed a hot tub culture by warming themselves in hot springs. The area around the zoo is designated as their wild habitat.

In the U.S., concerns over protecting native species' genes have arisen in relation to genetically engineered (GE) salmon produced by AquaBounty, Inc. and approved by the U.S. Food and Drug Administration in 2015.

Fears relating to GE salmon include the possibility they will mate with native species, introduce new diseases and/or compete for resources and habitat.

In 2010, world leaders agreed to 20 targets to protect Earth's biodiversity over the next decade. By 2020, none of them had been met. Now, the question is whether the world can do any better once new targets are set during the meeting of the UN Convention on Biodiversity in Kunming, China later this year.

The first 24 hours of the administration of President Joe Biden were filled not only with ceremony, but also with real action. Executive orders and other directives were quickly signed. More actions have followed. All consequential. Many provide a basis for not just undoing actions of the previous administration, but also making real advances in public policy to protect public health, safety, and the environment.

Takeaways

  • Your gut is home to trillions of bacteria that are vital for keeping you healthy.
  • Some of these microbes help to regulate the immune system.
  • New research, which has not yet been peer-reviewed, shows the presence of certain bacteria in the gut may reveal which people are more vulnerable to a more severe case of COVID-19.

You may not know it, but you have an army of microbes living inside of you that are essential for fighting off threats, including the virus that causes COVID-19.
