New Tortoise Species

New Mexican Tortoise Species

ROM-led research group finds new tortoise species. Click To Tweet I woke up this morning to see this headline in my local paper.  The article was short and sweet informing us that the Royal Ontario Museum in Toronto had its hand in discovering that a northern Mexican tortoise is in fact its own species.  I found this very cool as I live not far from Toronto and have visited this amazing museum countless times.

So….its not like they discovered a new species previously unknown to human kind.  But, it is very interesting in terms of biodiversity, that this species of turtle has been proven unique.

Because the Sinaloan lineage is genetically, ecologically and morphologically distinct from its congeners, … we describe it as a new species. — Edwards T, Karl AE et al.

New species of Mexican tortoise

For 150 years, a trio of tortoises including the Agassiz’s Desert Tortoise and the Morafka’s Desert Tortoise found further north were thought to be a single species. This group of tortoises ranging from southern Utah and Arizona to southern Sonora have gradually been found to be three separate species with the now Goode’s Thornscrub Tortoise (Gopherus evgoodei) announced as its own separate species status this year.

Prognosis for this New Mexican Tortoise Species

According to an article in the journal ZooKeys, this new Mexican tortoise species, Gopherus evgoodei has the smallest range of these three tortoise species.  It occurs only in the Sinaloan Thornscrub, and Tropical Deciduous Forest in the southern Sonoran Desert in Mexico.  This area represents some of the most threatened habitat of any of the desert tortoises.  So this new species’ conservation status is precarious but as not much is known about its ecology, its status can’t as yet be classified.

Ranchers changing native thornscrub to buffelgrass pasture poses the greatest threat to these creatures as it reduces the shade vegetation required to cool these cold-blooded creatures.  Naturally protected areas in Mexico found within the range of G. evgoodei and partial re-purposing of private ranches as hunting and conservation reserves give hope that these creatures will survive.

Known for his role in ensuring the global survival of turtles and tortoises, Eric Goode was awarded the honor of having this new species named after him.

What do you think about the research into our planet’s biodiversity?  Finding new species is always cool, I think. Finding them while there’s still time to do something about saving them is even better.  As always, leave your thoughts in the comment section.
