However, half of this diversity has been listed in a conservation threat category (IUCN, 2021) due to deforestation, agricultural and mining activities, emerging infectious diseases and pollution (Stuart et al., 2004; Lips et al., 2008; Ruíz-Carranza & Rueda- Almonacid, 2008; Isaacs-Cubides & Urbina-Cardona, 2011). Additionally, in expeditions to type localities and/or their surrounding areas to search for some species of the genus Pristimantis many of these have not been found, remaining known only from their formal description, which alerts us to the possibility that they may now be extinct (e.g. Pristimantis lichenoides, Pristimantis torrenticola, Duarte-Marín et al., 2018; Pristimantis cacao, Pristimantis diogenes, Pisso-Flórez et al., 2018; Pristimantis anolirex, Acevedo et al., 2018).

    Hibernation cell construction by the viviparous lizard Zootoca vivipara

To survive cold winter conditions, viviparous lizards hibernate in suitable shelters where they remain torpid until warmer weather prevails. The lizard has evolved some remarkable physiological adaptations to survive freezing winters and consequently can endure subzero temperatures in either a supercooled or a frozen state (Costanzol et al., 1995) but the lizard's choice of hibernaculum is also relevant to its survival. However, Beebee and Griffiths (2000) noted in relation to this species in Britain that, "We still know little about the hibernacula, but they are probably frost free refugia below ground or beneath large rocks or woodpiles." In a subsequent study of Z. vivipara hibernation in Siberia, Berman et al. (2016) report that all hibernating lizards were in various distinct cavities: burrows of the dung beetle Anoplotrupes stercorosus, tunnels left behind by decomposed roots, etc. No hibernating lizards were found in areas with loose soil. They concluded that the presence of small and stable cavities may be a necessary condition for hibernation. Furthermore, they suggest that relatively dry soil is required, as lizards survived hibernation at sub-zero temperatures in soil at 15 % moisture content (m.c.) but under experimental conditions all died at 70-80 % m.c.

    An unusual record of ophiophagy and necrophagy in the common boa Boa constrictor in the Brazilian Atlantic Forest

    查看更多>>摘要：The common boa (Boa constrictor) is a large snake, reaching more than 3 metres long. It is widely distributed in South America and recognised as an opportunistic and generalist predator, feeding on invertebrates, fish, birds, mammals, amphibians and lizards, primarily using constriction to subdue its prey (Henderson et al., 1995; Quick et al., 2005; Pizzato et al., 2009; Marques et al., 2019). Herein, we present the first record of ophiophagy and necrophagy for a common boa that ingested a dead Patagonian green racer Pseudablabes (Philodryas) patagoniensis (Girard, 1858).

    A case of cannibalism in Podarcis muralis from Dorset, England

    查看更多>>摘要：The common wall lizard (Podarcis muralis) is the most widespread species of the genus Podarcis in Europe, ranging from Iberia to the Balkan peninsula. Moreover, it has been introduced into Britain, Belgium, the Netherlands, Germany, and even north America (Speybroeck et al., 2016). It is a small-sized lacertid, reaching a total of 22 cm in length, with a rather polymorphic brown to green pattern (Sacchi et al., 2013). Like most Podarcis spp., it feeds mainly on arthropods (Bombi & Bologna, 2002), but also on gastropods, annelids, small vertebrates, and plants (Barbault & Mou, 1986). It may also consume other lizards, when they are smaller than themselves, as evidenced by the predation of a Zootoca vivipara by an adult male P. muralis in Britain (Thomas et al., 2020). Here we report a case of cannibalism that took place in Boscombe cliffs, Dorset (50° 43'15.7" N, 1° 49'29.6" W). According to Michaelides et al. (2015), this population results from a secondary introduction (from a naturalised non-native English population) of Venetian origin (Bologna, Italy).
