“…The above constitute mechanisms that maximize the amount of secretion in a "low pressure" system (Taub 1967, Kardong and Lavin-Murcio 1993, Weinsten et al 2013, lacking muscular insertions in the venom glands typical of snakes with anterior venom fangs. The bite and neurotoxicity of the secretion may play an important role in predation by H. viridiflavus, which takes a wide variety of prey (Filippi et al 2003, Mondino et al 2022 despite that it cannot be considered a "constrictor" snake.…”

Analysis of the maxillary, palatine, pterygoid, and dentary bones of the Western Whipsnake, Hierophis viridiflavus carbonarius, revealed the presenceof grooves and ridges in the teeth on the four dentiferous bones. Enlarged and modified rear teeth were found on the posterior maxillaries, separated by alveolar diastema and aligned differently from the anterior maxillary teeth. In both live and dissected specimens, Duvernoy’s gland, associated with the production of toxins, surrounds the rear maxillary teeth, which deliver the secretions produced by the gland. These characters, plus theinfliction of prolonged bites, facilitate the subduing of prey. The morphology of the palatomaxillary arch places H. viridiflavus in the group of opisthoglyphous colubroids, whose modified fangs facilitate the inoculation of secretions, considered a “primitive form of venom.” Other species of large sympatric colubroids were also examined, and some analogous structures were observed.

Anatolia: A Hotspot of Avian Genetic Diversity in the Western Palaearctic

Located at the crossroads of two continents and at the southeastern edge of the Mediterranean Basin, Anatolia was one of the most important Pleistocene glacial refugia in the Western Palaearctic. As part of the Irano-Anatolian, Caucasus and Mediterranean Basin biodiversity hotspots, this region is also home to a rich avian community including nearly 400 breeding species. Nevertheless, research addressing the genetic structure and diversity of local bird populations is limited, and information on glacial refugia in this region is still scant, especially when compared to other large Mediterranean peninsulas, namely the Balkan, Italian and Iberian ones. In this study, we contribute to filling this gap by addressing the biogeographic pattern of four common resident songbirds—the Eurasian blue tit (Cyanistes caeruleus), the great tit (Parus major), the Eurasian chaffinch (Fringilla coelebs) and the Eurasian blackbird (Turdus merula)—and one endemic species—the Krüper’s nuthatch (Sitta krueperi)—by amplifying two mitochondrial DNA genes in individuals from Anatolia (n = 329) and comparing their sequences to those of conspecifics from the rest of their distribution range across the western Palaearctic (n = 357) deposited in public databases. The overall genetic structure of these species is consistent with a scenario of isolation for multiple populations in different refugia across Anatolia and subsequent secondary contact in the wake of ice retreat, which makes this region a hotspot of genetic diversity for both widespread and endemic avian species.

“…Adult H. viridiflavus in nature have a very broad food spectrum (Filippi et al 2003, Lelièvre et al 2012, Mondino et al 2022, although there is no shortage of documented episodes of ophiophagy (Capula et al 2014) and cannibalism. This broad food spectrum makes H. viridiflavus one of the most opportunistic European snakes and may suggest that the males of the two abovementioned episodes likely fed on the eggs produced by the co-occupying females opportunistically, not distinguishing whether the deposited eggs belonged to their own species or not.…”

Intraspecific oophagy in Hierophis viridiflavus (Serpentes: Colubridae) during oviposition in a controlled environment

Following the observation of adult pairs of the Western Whipsnake, Hierophis viridiflavus, in a controlled environment, two distinct but related phenomena were observed: egg deposition and predation of freshly laid eggs by the male. Data about deposition, number and morphology of the eggs, hatching and offspring are presented and compared with the literature. The episode of oophagy is described, confirming the inclination to predate snake eggs and intraspecific oophagy in this species.
