Why animal culture matters for conservation
21 April 2021
Researchers say conservation of some of the world’s most endangered species needs to take cultural knowledge of animals into account when working out how best to protect them.
An international group of scientists, including Dr Emma Carroll from the University of Auckland, have come up with a ‘roadmap’ to help conservationists make the best decisions when implementing measures to help save them.
Like humans, species such as elephants, chimpanzees and whales learn from each other. For example, meerkat pups learn how to hunt scorpions by copying adults, and whales learn migratory routes from their mothers. Over time, learned behaviour can create differences between groups of animals which shape how they forage, migrate and communicate.
Beyond conserving genetic diversity, the authors of the paper published in Proceedings of the Royal Society B argue that understanding these socially learned behavioural differences between groups can guide decisions on how to define units (groups) to protect. It can also inform practical conservation measures, such as teaching anti-predator behaviours, or even seeding migratory routes for animals undergoing reintroduction to the wild.
“By conserving the ability of populations and groups of animals to socially learn, we help ensure they have the ability to rapidly learn how to exploit new food or habitat resources,” says Dr Carroll. “Conversely, some species are culturally ‘conservative’ which may mean they focus on key resources, like particular types of food that need to be conserved.”
For example, socially learned migration routes by beluga whales may be important to prevent entrapment in sea ice; understanding how crop-raiding behaviour in elephants is spread across social groups can assist in the management of these behaviours; and social learning may even provide opportunities for rapid assessment, for example in New Caledonian crows, where vocal dialects may provide ‘markers’ for rapidly mapping variation in tool-assisted foraging behaviour.
“Conservation practice has long been guided by genetics and ecology that assess how unique or connected different groups of animals are” says lead author Philippa Brakes of Whale and Dolphin Conservation. “We show that social learning and animal culture is another important facet of biology that can guide effective conservation strategies.”
The Convention on the Conservation of Migratory Species of Wild Animals (CMS) – widely known as the Bonn Convention – which operates under the aegis of the United Nations Environment Programme (UNEP), has been a pioneer in this field, spearheading efforts to use scientific knowledge on animal cultures to improve the conservation of migratory species.
