Amid the concrete jungle of New York City, nature has a way of surprising us. Biologists have unveiled a remarkable discovery—a new species of leopard frog quietly residing in the city that never sleeps. This frog, named Rana kauffeldi, marks only the second new frog species found in the continental United States in the past three decades. In this article, we’ll delve into the fascinating story of this native New Yorker frog and what makes it so unique.

A City of Surprises: Discovering Rana Kauffeldi

Amidst the hustle and bustle of New York City, researchers stumbled upon a revelation that left them astounded. Led by Rutgers University ecologist Jeremy Feinberg and a team of dedicated scientists, the 2014 discovery of R. kauffeldi, the new leopard frog species, was a groundbreaking moment.

Did You Know? R. kauffeldi is only the second new frog species identified in the continental United States in the last 30 years.

Unveiling the Genetic Mystery

The initial unveiling of this newfound amphibian was made in a journal called “Molecular Phylogenetics and Evolution.” In their research, scientists focused primarily on the genetic distinctions of this previously unidentified frog, initially classified as a southern leopard frog.

What Sets Rana Kauffeldi Apart

Rana kauffeldi boasts distinctive features that set it apart. While its skin displays subtle but unique spots, its most defining characteristic is the distinct mating call of the males. Unlike the pulsing and snore-like calls of other leopard frog species in the region, R. kauffeldi‘s call is described as a “single-note unpulsed chuck.”

Did You Know? This new species is named after the renowned herpetologist Carl Kauffeld, who had speculated about a yet-undiscovered leopard frog in New York City during the mid-20th century.

Habitat and Survival

Rana kauffeldi predominantly thrives in open-canopied coastal marshes and bottomland floodplains near river mouths. It’s an incredibly elusive species due to its brief breeding period, which coincides with the chorus of spring peepers. This unique timing has helped keep the frog hidden from casual observers.

Did You Know? R. kauffeldi‘s habitat is largely fragmented, and many areas where it was once found have been lost to urban development.

A Survivor in the City

Despite the challenges posed by urban development and habitat loss, R. kauffeldi has displayed remarkable resilience. It has managed to resist the devastating chytrid fungal disease, which has decimated amphibian populations elsewhere. This tenacity to survive echoes the spirit of New York City itself.
