A recent scientific study has shed light on an unexpected discovery in a town within the Greater Moncton area. Researchers from Mount Allison University uncovered a previously unknown population of the four-toed salamander in Riverview in 2023, a species typically confined to a specific type of bog in Fundy National Park. This finding suggests that the salamanders may possess greater resilience than previously believed.
According to Josh Christiansen, the lead author of the publication detailing the discovery, these salamanders are small, measuring around seven centimeters and sporting a distinctive rusty brown color. Notably, each salamander displays a unique salt and pepper pattern on its belly. Christiansen emphasized that these creatures are habitat specialists, requiring specific conditions to facilitate respiration through their skin and oral tissue.
Typically, the four-toed salamanders inhabit forested areas abundant in ground cover like leaf litter and fallen logs, creating microhabitats ideal for their survival. They also rely on bogs featuring sphagnum moss, avoiding open water with fish that pose a threat to their offspring. While this species has a broad range in North America, Fundy National Park was previously the sole documented location in New Brunswick due to its specialized habitat requirements.
The discovery of the salamanders in Riverview was serendipitous, as the researchers were originally searching for a different species. Once the find was shared, fellow scientists expressed astonishment and joined in exploring the site, uncovering more salamanders. The newly discovered population’s exact location remains undisclosed to safeguard its well-being, although it is situated near urban development and roads, within a maintained bog amidst a patch of forest.
Christiansen expressed a desire to identify additional locations where the species may thrive while emphasizing the need for conservation measures to protect these unique creatures and their habitats in urban settings. The goal is to ensure that disturbances to the bogs and forests are minimized to safeguard the salamanders’ continued existence.
