Scale Sensillae of the File Snake (Serpentes: Acrochordidae) and Some Other Aquatic and Burrowing Snakes
SCALE SENSILLAE OF THE FILE SNAKE (SERPENTES: ACROCHORDIDAE) AND SOME OTHER AQUATIC AND BURROWING SNAKES by DAVID POVEL and JEROEN VAN DER KOOIJ (Section Dynamic Morphology,Institute of Evolutionaryand Ecological Sciences, Leiden University,P.O. Box 9516, 2300 RA Leiden, The Netherlands) ABSTRACT The acrochordid snakes are aquatic, living in environmentswith often a poor visibility. It therefore was investigatedhow these animals detect their prey. Two earlier studies of their scales revealed a rather complex scale organ, composedof hairlike protrusions and plate-like structures. However, no satisfactory explanation was given for the structures found, e.g., an undefined sensilla or a gland. Skin samples from various sites of the body of Acrochordus granulatus and A. javanicus were studied. Scanning electron microscopic pictures revealed that each scale of the head contains up to seven sensillae, and each of the keeled scales of the rest of the body has one. Also a modified Allochrome staining procedure on tissue samples was performed to detect glycogen, which is known to occur in discoidal nerve endings of tactile sense organs of reptiles. Light microscopicslides revealedglycogen particles in a small pillow-shaped area just below the hairlike protrusions of an organ. Moreover, small nerves were recognized near the same location. No indications were found for the scale organs to have a glandular function. Because of the reported reactions of a snake when it is touched by a fish, these scale sensilla are proposed to be very sensitivemechanoreceptors. Comparisons were made with the scale organs of snakes from various habitats, viz. the seasnake Lapemis hardwicki, and burrowing snakes such as Xenopeltis unicolor and Cylindrophisrufus. -
Snakes of the Siwalik Group (Miocene of Pakistan): Systematics and Relationship to Environmental Change
Palaeontologia Electronica http://palaeo-electronica.org SNAKES OF THE SIWALIK GROUP (MIOCENE OF PAKISTAN): SYSTEMATICS AND RELATIONSHIP TO ENVIRONMENTAL CHANGE Jason J. Head ABSTRACT The lower and middle Siwalik Group of the Potwar Plateau, Pakistan (Miocene, approximately 18 to 3.5 Ma) is a continuous fluvial sequence that preserves a dense fossil record of snakes. The record consists of approximately 1,500 vertebrae derived from surface-collection and screen-washing of bulk matrix. This record represents 12 identifiable taxa and morphotypes, including Python sp., Acrochordus dehmi, Ganso- phis potwarensis gen. et sp. nov., Bungarus sp., Chotaophis padhriensis, gen. et sp. nov., and Sivaophis downsi gen. et sp. nov. The record is dominated by Acrochordus dehmi, a fully-aquatic taxon, but diversity increases among terrestrial and semi-aquatic taxa beginning at approximately 10 Ma, roughly coeval with proxy data indicating the inception of the Asian monsoons and increasing seasonality on the Potwar Plateau. Taxonomic differences between the Siwalik Group and coeval European faunas indi- cate that South Asia was a distinct biogeographic theater from Europe by the middle Miocene. Differences between the Siwalik Group and extant snake faunas indicate sig- nificant environmental changes on the Plateau after the last fossil snake occurrences in the Siwalik section. Jason J.

Ship Rats and Island Reptiles: Patterns of Co-Existence in the Mediterranean
Ship rats and island reptiles: patterns of co-existence in the Mediterranean Daniel Escoriza GRECO, University of Girona, Girona, Girona, Spain ABSTRACT Background. The western Mediterranean archipelagos have a rich endemic fauna, which includes five species of reptiles. Most of these archipelagos were colonized since early historic times by anthropochoric fauna, such as ship rats (Rattus rattus). Here, I evaluated the influence of ship rats on the occurrence of island reptiles, including non-endemic species. Methodology. I analysed a presence-absence database encompassing 159 islands (Balearic Islands, Provence Islands, Corso-Sardinian Islands, Tuscan Archipelago, and Galite) using Bayesian-regularized logistic regression. Results. The analysis indicated that ship rats do not influence the occurrence of endemic island reptiles, even on small islands. Moreover, Rattus rattus co-occurred positively with two species of non-endemic reptiles, including a nocturnal gecko, a guild considered particularly vulnerable to predation by rats. Overall, the analyses showed a very different pattern than that documented in other regions of the globe, possibly attributable to a long history of coexistence.

Biologic Environmental Survey, 24–26 Wickham St, East Perth, Western Australia 6004, Australia. Email: [email protected] ABSTRACT – The Western Australian Museum holds a vast collection of specimens representing a large portion of the 106 currently recognised taxa of dragon lizards (family Agamidae) known to occur across Australia. While the museum’s collection is dominated by Western Australian species, it also contains a selection of specimens from localities in other Australian states and a small selection from outside of Australia. Currently the museum’s collection contains 18,914 agamid specimens representing 89 of the 106 currently recognised taxa from across Australia and 27 from outside of Australia. This includes 824 type specimens representing 45 currently recognised taxa and three synonymised taxa, comprising 43 holotypes, three syntypes and 779 paratypes. Of the paratypes, a total of 43 specimens have been gifted to other collections, disposed or could not be located and are considered lost. An annotated catalogue is provided for all agamid type material currently and previously maintained in the herpetological collection of the Western Australian Museum. KEYWORDS: type specimens, holotype, syntype, paratype, dragon lizard, nomenclature.

2020 Conservation Outlook Assessment
IUCN World Heritage Outlook: https://worldheritageoutlook.iucn.org/ Vallée de Mai Nature Reserve - 2020 Conservation Outlook Assessment Vallée de Mai Nature Reserve 2020 Conservation Outlook Assessment SITE INFORMATION Country: Seychelles Inscribed in: 1983 Criteria: (vii) (viii) (ix) (x) In the heart of the small island of Praslin, the reserve has the vestiges of a natural palm forest preserved in almost its original state. The famouscoco de mer, from a palm-tree once believed to grow in the depths of the sea, is the largest seed in the plant kingdom. © UNESCO SUMMARY 2020 Conservation Outlook Finalised on 01 Dec 2020 GOOD WITH SOME CONCERNS The protection and management of Vallée de Mai Nature Reserve is generally effective and is supported by a national legal framework, although there is a lack of a national protected area system. The management authority is very competent and is effectively implementing science-based programs and outreach and education schemes. However, the future of the site’s key value, the coco de mer palm, is still under threat from illegal collection and over-exploitation for its nuts and kernel. The site's management has reduced both commercial harvesting and illegal collection of nuts based on scientific research, although the conservation impacts of these requires further assessment. The National Government and the managing agency are implementing targeted conservation measures and aim to tighten law and legislation to protect the species, which include an increase in penalty for poaching of coco de mer nuts. Current priorities for the Nature Reserve include continuation and expansion of the outreach and education programme; promoting an increase in the size and connectivity of Vallée de Mai within the Praslin Island landscape, with a legally designated buffer zone; increasing anti-poaching; and continuing to control the harvesting of coco de mer seeds while expanding a program of replanting seedlings. -

History of Classifications and Phylogenies the Arid Corridor From
APPENDIX Abstracts of presentations hold on DEAGAMIS the 1ST INTERNATIONAL SYMPOSIUM ON AGAMID LIZARDS ORAL PRESENTATIONS History of Classifications and Phylogenies Scott M. MOODY Department of Biological Science, Irvine Hall, Ohio University, Athens, OH, 45701, USA; Email: [email protected]. DARWIN in his 1859 “Origin of species ...” eloquently demonstrated that taxonomic classifications could (and should) reflect the past evolutionary history of higher taxa and relationships of the extant species. However the major her- petological works, for example, BOULENGER’s Catalogue of Lizards, published over the next 100 years did not attempt reconstructions of phylogeny. Indeed BOULENGER reversed the earlier named (now recognized again) genera and high- er taxa proposed especially by W. PETERS and L. FITZINGER. Although, CAMP (Classification of Lizards, 1923) and HENNIG (Revision of Draco, 1936) published pioneering works (they were decades ahead of others) the taxonomic herpetologists ignored them until the “rebirth” of phylogenetic systematics in the 1960’s and 1970’s. MOODY (1980) published a phylogenetic analysis based on 122 morphological characters and reviewed the historical biogeography of the agamid genera and proposed several subfamilies. Within the past two decades beginning with JOGER (1991, a molecular phylogeny of agamid lizards) several workers have employed molecular analyses. The hypothesized mo- lecular phylogenies by MACEY, LARSON, ANANJEVA, PAPENFUSS, OTA, HONDA, SCHULTE and MELVILLE will be com- pared with my original and revised morphologically based hypotheses. The controversy over the familial status of the various higher taxa within the “acrodont” section of the suborder Iguania that ensued following FROST & ETHERIDGE (1989) also will be reviewed.
