Substrate Thermal Properties Influence Ventral Brightness Evolution In
ARTICLE https://doi.org/10.1038/s42003-020-01524-w OPEN Substrate thermal properties influence ventral brightness evolution in ectotherms ✉ Jonathan Goldenberg 1 , Liliana D’Alba 1, Karen Bisschop 2,3, Bram Vanthournout1 & Matthew D. Shawkey 1 1234567890():,; The thermal environment can affect the evolution of morpho-behavioral adaptations of ectotherms. Heat is transferred from substrates to organisms by conduction and reflected radiation. Because brightness influences the degree of heat absorption, substrates could affect the evolution of integumentary optical properties. Here, we show that vipers (Squa- mata:Viperidae) inhabiting hot, highly radiative and superficially conductive substrates have evolved bright ventra for efficient heat transfer. We analyzed the brightness of 4161 publicly available images from 126 species, and we found that substrate type, alongside latitude and body mass, strongly influences ventral brightness. Substrate type also significantly affects dorsal brightness, but this is associated with different selective forces: activity-pattern and altitude. Ancestral estimation analysis suggests that the ancestral ventral condition was likely moderately bright and, following divergence events, some species convergently increased their brightness. Vipers diversified during the Miocene and the enhancement of ventral brightness may have facilitated the exploitation of arid grounds. We provide evidence that integument brightness can impact the behavioral ecology of ectotherms. 1 Evolution and Optics of Nanostructures group, Department -
Venomous Snakes of the Horn of Africa
VENOMOUS SNAKES OF THE HORN OF AFRICA Venomous Snake Identification Burrowing Asps Boomslang, Vine and Tree Snakes Snakebite Prevention Behavior: Venomous snakes are found throughout the Horn of Africa. Assume that any snake you encounter is venomous. Leave Long, Flattened Head, Round Fixed Front Smooth Long, Cylindrical Behavior: Burrowing asps spend the majority of time underground in burrows under stones, concrete slabs, logs, snakes alone. Many people are bitten because they try to kill a snake or get a closer look at it. Slightly Distinct from Neck Pupils Fangs Scales Body, Thin Tail They are active during both the daytime and nighttime. or wooden planks. 5-8 feet in length They live in trees and feed on bats, birds, and lizards. They are active on the surface only during the nighttime hours or after heavy rains flood their burrows. They are not aggressive: will quickly flee to nearest tree or bush if surprised on ground. Snakebites occur most often: MAMBAS They feed on small reptiles and rodents found in holes or underground. They do not climb. When molested, they inflate their bodies or necks as threat posture before biting. After rainstorms that follow long, dry spells or after rains in desert areas. Dendroaspis spp. SAVANNA VINE They are not aggressive: bites usually occur at night when snakes are stepped on accidentally. SNAKE During the half-hour before total darkness and the first two hours after dark. Habitats: Trees next to caves, coastal bush and reeds, tropical forests, open savannas, Thelotornis Habitats: Burrows in sand or soft soil, semi-desert areas, woodlands, and savannas. -
A Division of the African Tree Viper Genus Atheris Cope, 1860 Into Four Subgenera (Serpentes:Viperidae)

Phone: +61 3 9812 3322 Fax: 9812 3355 E-mail: [email protected] Received 15 February 2012, Accepted 2 April 2012, Published 30 April 2012. ABSTRACT The African Tree Viper genus Atheris has been of interest to taxonomists in recent years. Significant was the removal of the species superciliaris to the newly created monotypic genus Proatheris and the species hindii to the monotypic genus Montatheris both by Broadley in 1996 gaining widespread acceptance. Marx and Rabb (1965), erected a monotypic genus Adenorhinos for the species barbouri, but this designation has not gained widespread support from other herpetologists, with a number of recent classifications continuing to place the taxon within Atheris (e.g. Menegon et. al. 2011). Phylogenetic studies of the genus Atheris senso lato using molecular methods (e.g. Pyron et. al. 2011) have upheld the validity of the creation of the monotypic genera Proatheris and Montatheris by Broadley. These studies have also shown there to be at least four well-defined groups of species within the genus Atheris as recognized in early 2012, though not as divergent as seen for the snakes placed within Proatheris and Montatheris. As a result, the genus is now subdivided into subgenera using available names for three, with the fourth one being named Woolfvipera subgen. -

Parasites of domestic and wild animals in South Africa. XLVII. Ticks of tortoises and other reptiles. Onderstepoort Journal of Veterinary Research, 73:215–227 A total of 586 reptiles, belonging to 35 species and five subspecies, were examined in surveys aimed at determining the species spectrum and geographic distribution of ticks that infest them. Of these rep- tiles 509 were tortoises, 28 monitor or other lizards, and 49 snakes. Nine ixodid tick species, of which seven belonged to the genus Amblyomma, and one argasid tick, Ornithodoros compactus were re- covered. Seven of the ten tick species are parasites of reptiles. Amongst these seven species Am bly- omma marmoreum was most prevalent and numerous on leopard tortoises, Geochelone pardalis; Amblyomma nuttalli was present only on Bell’s hinged tortoises, Kinixys belliana; and most Amblyomma sylvaticum were collected from angulate tortoises, Chersina angulata. Amblyomma exornatum (for- merly Aponomma exornatum) was only recovered from monitor lizards, Varanus spp.; most Ambly- omma latum (formerly Aponomma latum) were from snakes; and a single nymph of Amblyomma trans versale (formerly Aponomma transversale) was collected from a southern African python, Python natalensis.

Calibrating the Tree of Vipers Under the Fossilized Birth-Death Model Jiří Šmíd 1,2,3,4 & Krystal A
www.nature.com/scientificreports OPEN Calibrating the tree of vipers under the fossilized birth-death model Jiří Šmíd 1,2,3,4 & Krystal A. Tolley 1,5 Scaling evolutionary trees to time is essential for understanding the origins of clades. Recently Received: 18 September 2018 developed methods allow including the entire fossil record known for the group of interest and Accepted: 15 February 2019 eliminated the need for specifying prior distributions for node ages. Here we apply the fossilized birth- Published: xx xx xxxx death (FBD) approach to reconstruct the diversifcation timeline of the viperines (subfamily Viperinae). Viperinae are an Old World snake subfamily comprising 102 species from 13 genera. The fossil record of vipers is fairly rich and well assignable to clades due to the unique vertebral and fang morphology. We use an unprecedented sampling of 83 modern species and 13 genetic markers in combination with 197 fossils representing 28 extinct taxa to reconstruct a time-calibrated phylogeny of the Viperinae. Our results suggest a late Eocene-early Oligocene origin with several diversifcation events following soon after the group’s establishment. The age estimates inferred with the FBD model correspond to those from previous studies that were based on node dating but FBD provides notably narrower credible intervals around the node ages. Viperines comprise two African and an Eurasian clade, but the ancestral origin of the subfamily is ambiguous. The most parsimonious scenarios require two transoceanic dispersals over the Tethys Sea during the Oligocene. Scaling phylogenetic trees to time is one of the major challenges in evolutionary biology. Reliable estimates for the age of evolutionary events are essential for addressing a wide array of questions, such as deciphering micro- and macroevolutionary processes, identifying drivers of biodiversity patterns, or understanding the origins of life1. -

Box 3030, Irbid, 11112, Jordan. amrz(at)just.edu.jo 2 Department of Biology, the University of Jordan, Amman, 11942, Jordan. ahmadmdisi(at)yahoo.com Accepted on June 18, 2011. Published online at www.vertebrate-zoology.de on June 22, 2011. > Abstract The present study consists of both locality records and of literary data for 37 species and subspecies of snakes reported from Jordan. Within the past decade snake taxonomy was re-evaluated employing molecular techniques that resulted in reconsideration of several taxa. Thus, it is imperative now to revise the taxonomic status of snakes in Jordan to update workers in Jordan and the surrounding countries with these nomenclatural changes. The snake fauna of Jordan consists of 37 species and subspecies belonging to seven families (Typhlopidae, Leptotyphlopidae, Boidae, Colubridae, Atractaspididae, Elapidae and Viperidae). Families Leptotyphlopidae, Boidae and Elapidae are represented by a single species each, Leptotyphlops macrorhynchus, Eryx jaculus and Walterinnesia aegyptia respectively. The families Typhlopidae and Atractaspididae are represented by two and three species respectively. Species of the former genus Coluber were updated and the newly adopted names are included. Family Colubridae is represented by twelve genera (Dolichophis, Eirenis, Hemorrhois, Lytorhynchus, Malpolon, Natrix, Platyceps, Psammophis, Rhagerhis, Rhynchocalamus, Spalerosophis and Telescopus) and includes 24 species. Family Viperidae includes fi ve genera (Cerastes, Daboia, Echis, Macrovipera and Pseudocerastes), each of which is represented by a single species, except the genus Cerastes which is represented by two subspecies. -
