Rediscovering the Golden Mole Thought to Be Extinct
Scent-Detecting Dog Leads to the Discovery
Thanks to the keen nose of a border collie named Jessie, a team of scientists has rediscovered a species of golden mole once thought to be extinct. The De Winton’s golden mole, a critically endangered mammal, had not been definitively seen since 1936.
DNA Evidence Confirms Presence
To confirm their discovery, the researchers needed both a photo of the creature and DNA evidence. As the De Winton’s golden mole closely resembles other golden mole species, DNA analysis was crucial.
Environmental DNA: A Non-Invasive Approach
The researchers collected environmental DNA (eDNA), genetic material shed by organisms that can be extracted from the environment. This innovative technique allowed them to identify the presence of animals without capturing or even seeing them.
Mapping the Distribution
Using eDNA data, the team mapped the distribution of four golden mole species along South Africa’s west coast, including De Winton’s golden mole. This information is vital for conservation efforts.
Conservation Concerns
Diamond mining poses a significant threat to the habitat of De Winton’s golden mole. The researchers emphasize the need for further research to determine the abundance and distribution of this endangered species.
The Importance of Conservation
Conservationists stress the importance of protecting rare and endangered species like the De Winton’s golden mole. They call for the establishment of protected areas and increased conservation efforts to ensure the survival of these unique creatures.
Golden Moles: Remarkable Adaptations
Golden moles are blind, but they possess remarkable navigational abilities and enhanced hearing that allow them to detect prey underground. Their iridescent oil lubricates their fur, enabling them to dig through sand with ease.
Environmental DNA: A Powerful Tool
Environmental DNA is a valuable tool for studying endangered species that are difficult to capture or observe. It provides insights into their presence, movement, and distribution.
The Role of Dogs in Conservation
Scent-detecting dogs like Jessie play a crucial role in conservation efforts. Their keen sense of smell can lead researchers to elusive species and aid in the detection of endangered animals.
Protecting the Golden Mole’s Future
The rediscovery of the De Winton’s golden mole highlights the importance of conservation efforts. By gathering more data on their distribution and abundance, scientists can develop targeted conservation strategies to protect this endangered species and its unique habitat.
