Uncovering Hidden Genes: Milk Frog Trachycephalus Typhonius Study

A new study, by Angela M. Mendoza-Henao , Juan Alejandro Guerrero-Cupacan, Khristian Venegas-Valencia & Mailyn A. Gonzalez (2025), shows that overcoming biases in geography and history factors can uncover hidden types of herpetiles (reptiles and amphibians).

It is known in the conservation field that biases are unfortunately common. An Australian study in 2025: "Location biases in ecological research on Australian terrestrial reptiles" by Renee Louise Piccolo,Jan Warnken, Alienor Louise Marie Chauvenet & James Guy Castley showed that:

"The strongest predictor of reptile research locations was proximity to universities (40.8%). This was followed by species richness (22.9%) and human footprint (20.1%), while protected areas were the weakest predictor (16.2%)."

Our comfortability could prove a hinderance for overlooked herpetiles, so much so, that it could be their silent killer.

Geographical and historical factors play a huge part in different types of the same animal. The differences can be seen in their appearance or genetic make-up.

Over a range of northern South American countries, 70 samples from 9 species of Milk Frog were analysed to reveal their ancestral significance. Splitting two of the species into having different direct descents and thus looks/genetics are contrasting. B and C above.

"Better knowledge, better decisions for the conservation of herpetofauna"

(Angela M. Mendoza-Henao , Juan Alejandro Guerrero-Cupacan, Khristian Venegas-Valencia & Mailyn A. Gonzalez, 2025)

The future should include all types of animals and locations so that we have a better understanding of their needs for survival. We can identify a more variety of life and possibly uncover some hidden species.
