“…Even though Bishop (1979) (Bobe, 2006). A similar split between Central and East African species occurred at the end of the Miocene, as has been already observed in numerous other taxa, including rodents (Bryja et al, 2014a;Bryja et al, 2017), snakes (Portillo et al, 2018) and duikers (Johnston and Anthony, 2012). These findings support a scenario in which continuous African Miocene forest became divided into the current Central and West African Guinea-Congolese forest the East African forests (Plana, 2004).…”

“…Phylogeographic differentiation seems to follow general paradigms, with distinct southern and northern population clusters, a pattern emerging also in other species (Bitis arietans, Barlow et al, 2013;Pelomedusa galeata, Vamberger et al, 2018;Trachylepis sulcata, Portik et al, 2011). Furthermore, the distribution of leopard tortoises of one northern subcluster (N3) matches the distribution ranges of an endemic snake species (Xenocalamus transvaalensis, Portillo et al, 2018), several endemic dwarf chameleon species (Bradypodion spp., Tilbury & Tolley, 2009) and a genetic lineage of the helmeted terrapin (P. galeata, Vamberger et al, 2018). With an increasing number of species studied genetically, more cases are expected to be reported.…”

“…Nevertheless, one of the three nuclear subclusters (N3) is confined to a small area at the border of South Africa (KwaZulu‐Natal) and Mozambique. The same region also has an endemic snake species ( Xenocalamus transvaalensis , Portillo et al, ), several endemic dwarf chameleon species ( Bradypodion spp., Tilbury & Tolley, ) and an endemic mitochondrial clade of the helmeted terrapin ( Pelomedusa galeata subclade Ib, Vamberger, Hofmeyr, Ihlow, & Fritz, ), suggesting high biogeographic differentiation. In fact, this region (Maputaland) together with two more southern regions constitutes the Maputaland‐Pondoland‐Albany hotspot, leftacterized by high plant and vertebrate endemism (Perera, Ratnayake‐Perera, & Procheş, ).…”

In contrast to mammals, little is known about the phylogeographic structuring of widely distributed African reptile species. With the present study, we contribute data for the leopard tortoise (Stigmochelys pardalis). It ranges from the Horn of Africa southward to South Africa and westwards to southern Angola. However, its natural occurrence is disputed for some southern regions. To clarify the situation, we used mtDNA sequences and 14 microsatellite loci from 204 individuals mainly from southern Africa. Our results retrieved five mitochondrial clades; one in the south and two in the north‐west and north‐east of southern Africa, respectively, plus two distributed further north. Using microsatellites, the southern clade matched with a well‐defined southern nuclear cluster, whilst the two northern clades from southern Africa corresponded to another nuclear cluster with three subclusters. One subcluster had a western and central distribution, another occurred mostly in the north‐east, and the third in a small eastern region (Maputaland), which forms part of a biodiversity hotspot. Genetic diversity was low in the south and high in the north of our study region, particularly in the north‐east. Our results refuted that translocations influenced the genetic structure of leopard tortoises substantially. We propose that Pleistocene climatic fluctuations caused leopard tortoises to retract to distinct refugia in southern and northern regions and ascribe the high genetic diversity in the north of southern Africa to genetic structuring caused by the survival in three refuges and subsequent admixture, whereas tortoises in the south seem to have survived in only one continuous coastal refuge.

“…To our knowledge, the venoms from these arthropod-eating species have not been studied. Among Lamprophiidae, the subfamily Atractaspidinae includes the rear-fanged genus Aparallactus (11 species) that feeds on centipedes (with the exception of Aparallactus modestus, a fangless species that feeds on earthworms; Portillo et al, 2018Portillo et al, , 2019.…”

“…Among Lamprophiidae, the following rear-fanged genera (belonging to the tribe Atractaspidinae) feed mostly on snakes and fossorial squamates: Amblyodipsas, Brachyophis, Chilorhinophis, Hypoptophis, Macrelaps, Polemon, and Xenocalamus (32 species; Portillo et al, 2018Portillo et al, , 2019. Given its peculiar dentition (enlarged front and back maxillary teeth), use of venom and inclusion of skinks in its diet, the "mock viper" (genus Psammodynastes, 2 species, family Lamprophiidae) also deserves special interest (Jackson and Fritts, 1996).…”

Snake Venom in Context: Neglected Clades and Concepts

2019

Despite the fact that venom is an intrinsically ecological trait, the ecological perspective has been widely neglected in toxinological research. This neglect has hindered our understanding of the evolution of venom by causing us to ignore the interactions which shape this evolution, interactions that take place between venomous snakes and their prey and predators, as well as among conspecific venomous snakes within populations. In this opinion piece, we introduce and briefly discuss several ecologically oriented concepts that may be of interest to toxinologists, before reviewing a range of non-front-fanged snake taxa that have been neglected toxinologically, but which represent the majority of extant ecological diversity amongst snakes. We conclude by noting that the ecological perspective even has something to offer to clinical toxinology, in the wake of the World Health Organization reinstating snakebite envenoming to its list of Neglected Tropical Diseases.
