Nuovo articolo scientifico :)
La vipera di Milos (Macrovipera schweizeri) è un affasciante viperide endemico delle sole isole greche di Milos, Kimolos, Polýaigos e Sifnos (Cicladi occidentali).
Sono orgoglioso di annunciare la pubblicazione, tramite la rivista scientifica Spixiana, del nostro lavoro riguardante la review estesa di quanto noto in letteratura per la specie (o sottospecie, dato che lo status tassonomico necessita di ulteriori approfondimenti) in termini di sistematica, origini, morfologia, ecologia, riproduzione, veleno e conservazione. Sono riportati, inoltre, alcuni dati osservati personalmente assieme all’amico Giovanni Paolino sull’attività autunnale.
Per chi volesse saperne di più su questo serpente, consiglio la lettura dell’articolo, disponibile gratuitamente al seguente link:

Buona lettura!

Ny Elaphe.
🚨New Species Alert!!🚨
A colubrid with bladed teeth!! Researchers suspect this new species is able to avoid predation by mimicking the syntopic pit-viper Protobothrops jerdonii.
Based on combined morphological and osteological characters and molecular phylogenetics, a new species has been described of the genus Elaphe that was discovered from the south slope of the Qinling Mountains, Shaanxi, China,

Thermal melanism explains macroevolutionary variation of dorsal pigmentation in Eurasian vipers Colouration may endorse thermoregulatory and antipredatory functions in snakes. The thermal melanism hypothesis predicts that dark-coloured individuals are ecologically favoured in cool climates. However, the loss of aposematic and cryptic colourations may imply high predation for melanistic snakes....

Where do you come from, stranger? A scientific-historical digression with discussion on nomenclature and taxonomy of Testudo graeca Linnaeus, 1758 It is shown that the location data for the terra typica restricta of Testudo graeca and for the terra typica designata for Testudo graeca are based on an incorrectly assigned location. In fact, the original place corresponds to Santa Cruz, known today as Agadir (Morocco) and not the old Spanish fort...

Bufo viridis :)
🐸 Pätnásť odtieňov zelenej…alebo čo by ste chceli vedieť o evolúcii, biogeografii a taxonómii ropúch rodu Bufotes.
Okrem iného sa dočítate o 15 druhoch rodu Bufotes skúmaných cez genomické, genetické a biometrické dáta, mitochondriálnych výmenách, pôvode allopolyploidných hybridov a rozsiahlych hybridizáciách, super-kryptickom koncepte druhu a výraznej taxonomickej revízii. Novo získané dáta tak viedli k opisu dvoch druhov Bufotes cypriensis Litvinchuk, Mazepa, Jablonski, Dufresnes, 2019 (endemit ostrova Cyprus) a Bufotes perrini Mazepa, Litvinchuk, Jablonski, Dufresnes, 2019 (endemit Strednej Ázie).
🐸Fifteen shades of green...or what you would like to know about the evolution, biogeography, and taxonomy of Bufotes toads.
Among other things, you can read about 15 species of the genus examined through genomic, genetic and biometric data, mitochondrial replacements, origin of allopolyploid hybrids and extensive hybridizations, super-cryptic species concept, and major taxonomic revision. New data supported a formal description of two new species, Bufotes cypriensis Litvinchuk, Mazepa, Jablonski, Dufresnes, 2019 (endemic to Cyprus) and Bufotes perrini Mazepa, Litvinchuk, Jablonski, Dufresnes, 2019 (endemic to Central Asia).
