A number of years in the past, after I started my biology research, I used to be taking a stroll in an Andean scrubland close to my hometown, Bogotá, and whereas admiring the twisted shapes of the shrub branches, I observed a small bright-green elongated spot on a department, which stood out from the encircling vegetation. The spot seemed like an altered imaginative and prescient produced by entheogenic substances. As I approached the spot, my nervousness elevated as a result of it was slowly rotating across the small department whereas I used to be getting nearer. However after I was shut sufficient to determine it, my nervousness ceased. It was not a hallucination, however a lizard, an Anolis heterodermus!
Some years later, my nervousness returned after I thought of the way forward for these lizards as a result of advance of a big metropolis hungry for concrete. We determined to analyze it by attempting to doc the dynamics of populations in scrublands surrounding Bogotá. Although town continued its inexorable progress, it appeared that these lizards had a number of methods to face the loss and fragmentation of their habitat, however provided that the city growth onslaught was not too sturdy. Thus, my nervousness ceased, however solely partially.
And I say partially as a result of whereas I captured, marked, and recaptured these lizards, I additionally puzzled why one species might exhibit such a disproportionate number of kinds, sizes, and colours. I calmed down when realized that Emmett Dunn and James Lazell in all probability felt the identical when going through that vast phenotypic variety in addition to different researchers who, with the appearance of the molecular period, expressed that variety in what we all know right now because the species complicated. Following the concepts of the brand new molecular period, we studied that species complicated and located at the least three impartial evolutionary lineages in a really small geographic space. Nonetheless, the uncertainty of the disproportionate variation in colours and shapes remained, so we determined to face it and tried to disclose the range of that species complicated that the Colombian biologist Miguel Méndez superbly known as “The best kingdom of Anolis.“
The relationships amongst some species of anoles of the heterodermus group. Determine modified from Moreno-Arias et al. (2023).
In our final analysis “Revealing anole variety within the highlands of the Northern Andes: New and resurrected species of the Anolis heterodermus species group,” the duty of gathering completely different traces of proof was easy on paper due to the many individuals supported us (Anthony Herrel, Juan Manuel Daza and Belisario Cepeda and different faculties that present specimens, tissues, and images of the species), however organizing and analyzing the info was not really easy, and it took us a number of years to do it. We expanded the molecular sampling, together with different species of the “kingdom” (extra formally the clade Phenacosurus), and documented at the least 9 independently developed lineages. We recognized teams of lizards primarily based on their morphometry, combining lizards with short-to-long legs, thin-to-wide toes, and small to massive our bodies.
We additionally recognized teams primarily based on scale counts that mixed lizards with extra or fewer scales on their head and dorsum, and teams of lizards primarily based on their scale sample that mixed lizards with U or V-shaped crowns, rows of scales of various sizes below their lips, and steady or discontinuous nuchal crests. Though much less clear than the earlier traces of proof, the physique coloration sample ranged from lizards with a predominance of uniform coloration patterns to lizards with stunning coloration mixtures. Probably the most fascinating grouping was the one primarily based on the colour sample of the dewlap, which was close-matched with the geographical distribution of lizards and their evolutionary historical past.
After gathering and analyzing completely different traces of proof, we examined their correspondence with the evolutionary historical past of the species. We discovered a low diploma of correspondence between physique coloration sample, morphometrics, and molecular proof, however the next diploma of correspondence between scalation sample, dewlap coloration sample, molecular proof, and geography. This correspondence allowed us to assist taxonomic novelties and to hypothesize the diversification of the species contemplating geological and environmental modifications related to the uplift of the Andes in northern South America.
These taxonomic novelties are summarized in 9 lineages that correspond to 4 beforehand described species, the resurrection of a species, A. richteri, which had been thought-about a synonym of A. heterodermus, two new species for science, and two lineages pending description. The 2 new species are paying homage to our pre-Columbian historical past: the title of A. tequendama sp. nov. derives from a sacred place essential within the cosmogony of the Muisca ethnicity (a human group inhabited the Cundiboyacense plateau and the place at the least three species of “The best kingdom of Anolis“ might be discovered) and the place a waterfall known as Salto de Tequendama is positioned. In response to Muisca mythology, the waterfall was created by a Bochica deity to empty the flood that the Muisca individuals suffered on account of their grievances towards the Chibchachum deity. The title A. quimbaya sp. nov. derives from a recognition of the Quimbaya ethnicity, which was well-known for its abilities in goldsmithing and which, regardless of its ferocity in fight, turned extinct after the Spanish colonization across the yr 1600.
Within the try and reveal variety in “the best kingdom of Anolis,” two lineages stay unnamed, to which we at present have restricted molecular data and just about no information of their genetic and phenotypic variety.
Now, in a hotter world, we will entry territories as soon as forbidden by our nation’s lengthy armed battle, but in addition can entry the insatiable starvation for financial growth…my nervousness returns, and new questions run via my head: what number of extra will inhabit the best kingdom of Anolis? Will we be capable to know them earlier than they disappear?
