A recent scientific study revealed an unexpected finding in the Greater Moncton area, where Mount Allison University researchers discovered a previously unknown population of four-toed salamanders in Riverview in 2023. These salamanders, typically found in a specific bog within Fundy National Park, are demonstrating a higher level of adaptability than initially believed.
Josh Christiansen, the lead author of the study, described the salamanders as small creatures measuring around seven centimetres in length with a rusty brown hue. Notably, each salamander possesses a distinctive salt and pepper pattern on its belly. Christiansen explained that these species are considered habitat specialists, requiring specific environmental conditions for respiration through their skin and mouth tissues.
Typically found in forested areas with abundant ground cover like leaf litter and fallen logs, the salamanders create microhabitats under these cover objects, providing an ideal living environment. They also rely on bogs with sphagnum moss, avoiding open waters with fish that may prey on their offspring.
The discovery of the four-toed salamanders in Riverview surprised scientists as this species had only been documented in Fundy National Park in New Brunswick due to their specialized habitat needs. The exact location of the newly discovered population remains undisclosed to ensure their protection. Despite being close to urban development and roads, the salamanders have adapted to a maintained bog within the area, emphasizing the importance of conservation efforts to safeguard their habitat. Christiansen expressed the desire to identify more potential locations where these salamanders may thrive while emphasizing the need for their protection in urban settings.
