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.

Forest Stewardship Workshop
Aquatic Invasives Workshop Presented by the: Central Florida Cooperative Invasive Species Management Area (CISMA), East Central Florida CISMA & Florida Forest Stewardship Program May 13, 2016; 8:30 am – 2:30 pm ET UF/IFAS Orange County Extension Office Many exotic plants are invasive weeds that form expanding populations on our landscape and waterways, making management a challenge. Some exotic animals have also become a problem for resource managers. The rapid and effective dispersal characteristics of these invaders make them extremely difficult to eliminate. This workshop will describe some of the more common and troublesome aquatic invasive exotic species in central Florida, current methods being used to manage them and opportunities to partner and get assistance.

Epidemiology of Snakebites from a General Hospital in Singapore: a 5-Year Retrospective Review (2004-2008) 1 Hock Heng Tan, MBBS, FRCS A&E (Edin), FAMS
640 Epidemiology of Snakebites—Hock Heng Tan Original Article Epidemiology of Snakebites from A General Hospital in Singapore: A 5-year Retrospective Review (2004-2008) 1 Hock Heng Tan, MBBS, FRCS A&E (Edin), FAMS Abstract Introduction: This is a retrospective study on the epidemiology of snakebites that were presented to an emergency department (ED) between 2004 and 2008. Materials and Methods: Snakebite cases were identified from International Classification of Diseases (ICD) code E905 and E906, as well as cases referred for eye injury from snake spit and records of antivenom use. Results: Fifty-two cases were identified: 13 patients witnessed the snake biting or spitting at them, 22 patients had fang marks and/or clinical features of envenomations and a snake was seen and the remaining 17 patients did not see any snake but had fang marks suggestive of snakebite. Most of the patients were young (mean age 33) and male (83%). The three most commonly identified snakes were cobras (7), pythons (4) and vipers (3). One third of cases occurred during work. Half of the bites were on the upper limbs and about half were on the lower limbs. One patient was spat in the eye by a cobra. Most of the patients (83%) arrived at the ED within 4 hours of the bite. Pain and swelling were the most common presentations. There were no significant systemic effects reported. Two patients had infection and 5 patients had elevated creatine kinase (>600U/L). Two thirds of the patients were admitted. One patient received antivenom therapy and 5 patients had some form of surgical intervention, of which 2 had residual disability. -

They feature prominently in folklore, mythology and other belief systems of the indigenous people of the region, and are of ecological and conservation value, some species supporting significant (albeit often illegal) economic activities (primarily, the snake-skin trade, but also sale of meat and other body parts that purportedly have medicinal properties). -
