In a recent scientific study, researchers from Mount Allison University made a surprising discovery in Riverview, a town in the Greater Moncton area. They found a previously unknown population of the four-toed salamander in 2023, a species typically found only in a specific type of bog in Fundy National Park. This discovery suggests that the salamander may possess greater adaptability than previously believed.
Describing the salamanders as small, measuring around seven centimeters and sporting a rusty brown color, lead researcher Josh Christiansen highlighted a unique salt and pepper pattern on their bellies, distinguishing each individual. Christiansen explained that these creatures are habitat specialists, requiring specific conditions to facilitate breathing through their skin and mouth tissues.
Typically inhabiting forested areas with ample ground cover like leaf litter and fallen logs, the salamanders create microhabitats beneath such cover objects. Additionally, they need bogs with sphagnum moss but avoid open waters with fish that pose a threat to their offspring.
Despite the four-toed salamander’s broad range across North America, it was previously documented solely in Fundy National Park in New Brunswick due to its specialized habitat requirements. The unexpected discovery in Riverview, while researchers were focusing on another species, garnered astonishment from the scientific community.
The researchers have not disclosed the exact location of the find, citing concerns about the population’s well-being. Christiansen mentioned that the site is near urban development and roads but emphasized the importance of protecting the salamanders’ habitat from disturbance. He expressed a desire to identify more potential locations for the species while advocating for conservation measures to safeguard their habitats in urban areas.
