Biotic and Abiotic Influences on Activity Patterns Of
Biological Conservation 97 (2001) 387±398 www.elsevier.com/locate/biocon Biotic and abiotic in¯uences on activity patterns of insular pit-vipers (Gloydius shedaoensis, Viperidae) from north-eastern China Li-xin Sun a, Richard Shine b,*, Zhao Debi a, Tang Zhengren a aSnake Island Protection District, Lushun, People's Republic of China bBiological Sciences A08, University of Sydney, NSW 2006, Australia Received 3 May 2000; received in revised form 18 July 2000; accepted 19 July 2000 Abstract In order to use counts of active animals to estimate population parameters (abundance, sex ratio, age structure), we need to understand the factors that bias such counts. For many taxa, the main problems involve behavioural dierences among age/sex classes, and the eects of local conditions on activity levels. A unique opportunity to quantify such eects on snakes occurs on Shedao, a small island in the Bohai Sea o north-eastern China. The island contains an extraordinary density of endemic pit-vipers (Gloydius shedaoensis), that feed primarily on migrating passerine birds. Over an 8-year period we walked the same 540-m path on 936 mornings during bird-migration periods, counted all pit-vipers within a 3-m-wide transect, and recorded the animals' sex and age class (adult vs juvenile). Total numbers of snakes averaged 40.6 per survey (0.31 per m): thus, the data set contains 37,980 records of sightings of snakes. The total numbers and the composition (sex ratio, age structure) of snakes seen in a morning diered among segments of the path, diered between seasons (spring versus autumn), diered with time within each season, and were in¯uenced by weather conditions (temperature, wind speed, relative humidity). -

Accepted November 11, 2005) SUMMARY: The mamushi (Gloydius blomhoffii) snakes that inhabit Japan, Korea, and China produce venoms with similar serological characters to each other. Individual domestic standard mamushi antivenoms have been used for national quality control (potency testing) of mamushi antivenom products in these countries, because of the lack of an international standard material authorized by the World Health Organization. This precludes comparison of the results of product potency testing among countries. We established a regional reference antivenom for these three Asian countries. This collaborative study indicated that the regional reference mamushi antivenom has an anti-lethal titer of 33,000 U/vial and anti-hemorrhagic titer of 36,000 U/vial. This reference can be used routinely for quality control, including national control of mamushi antivenom products. reference antivenom. INTRODUCTION In the present study, the potency of a candidate regional Snakebites are a threat to human life in areas inhabited by reference mamushi antivenom produced by Shanghai Insti- poisonous snakes. -

I could never have completed this work without their help. Dr. David Duvall, my former mentor, helped in various ways until the very end of his career at Oklahoma State University. This study was originally developed as an undergraduate research project under Dr. Duvall. Subsequently, he accepted me as his graduate student and helped me expand the project to this Ph.D. research. He gave me much key advice and conceptual ideas for this study. His encouragement helped me to get through several difficult times in my pursuit of a Ph.D. degree. He also gave me several books as a gift and as an encouragement to complete the degree. Dr. Stanley Fox kindly accepted to serve as my major adviser after Dr. Duvall’s departure from Oklahoma State University and involved himself and contributed substantially to this work, including analysis and editing. -

Climate Change and Evolution of the New World Pitviper Genus
Journal of Biogeography (J. Biogeogr.) (2009) 36, 1164–1180 ORIGINAL Climate change and evolution of the New ARTICLE World pitviper genus Agkistrodon (Viperidae) Michael E. Douglas1*, Marlis R.

Eagle Mountain, UT, USA Location Midwestern and eastern North America. Methods We reconstructed maximum parsimony (MP) and maximum likelihood (ML) relationships based on 846 base pairs of mitochondrial DNA (mtDNA) ATPase 8 and ATPase 6 genes sequenced over 178 individuals. We quantified range expansions, demographic histories, divergence dates and potential size differences among clades since their last period of rapid expansion. We used the Shimodaira–Hasegawa (SH) test to compare our ML tree against three biogeographical hypotheses. Results A significant SH test supported diversification of A. contortrix from northeastern Mexico into midwestern–eastern North America, where its trajectory was sundered by two vicariant events. The first (c. 5.1 Ma) segregated clades at 3.1% sequence divergence (SD) along a continental east–west moisture gradient. The second (c. 1.4 Ma) segregated clades at 2.4% SD along the Mississippi River, coincident with the formation of the modern Ohio River as a major meltwater tributary. -

Neotropical Biology and Conservation 15(1): 71–76. https://doi.org/10.3897/neotropical.15.e48564 Abstract Anti-predator mechanisms are essential for species survival and the description of defensive behav- iour may improve our understanding about the ecology, biology and evolution of species. Herein, we describe new anti-predator behaviour for the False Coral Snake Oxyrhopus rhombifer in south-eastern Brazil, through direct observation of a juvenile specimen under laboratory settings. We recorded 10 types of defensive behaviour, seven of which are new records for this species and one of them (body vibration) is the first report for Brazilian snakes. Such behaviour may be explained by ontogeny or physical constraints. -

Bites from one species, known as Japanese Mamushi, Gloydius Blomhoffii, are common in Japan. Some patients develop severe symptom, represented by rhabdomyolysis and acute renal failure, and in extreme cases, death has resulted mainly due to intestinal bleeding/necrosis and perforating peritonitis. The mortality rate is estimated to be about 1 death/300 bites. The lethal cases presented with severe abdominal symptoms, including melena and ileus, and the severe cases including the lethal cases present with higher creatinine kinase values and white blood cell counts. Therefore, it was found that these are reliable indicators predicting the severity of envenomation. The severe and non-severe cases can often be distinguished by the rate of elevation of these laboratory values. -

Here, we present an annotated species inventory of this under-explored area, with detailed notes on distributions and population statuses. Fieldwork was concentrated in southern Navoi and western Samarkand provinces, although some records were also made in the far north of Navoi province, near the city of Uchkuduk. Data were collected between March and May/June in 2011, 2012, and 2013, with herpetofaunal records being made opportunistically throughout this period. Survey effort was concentrated in semi-desert steppe habitats, especially the Karnabchul steppe area located to the south of the city of Navoi and an expanse of unnamed steppe located to the north of Navoi. Further records were made in a range of other habitat types, notably wetlands, sand dune fields, and low rocky mountains. Total fieldwork equated to approximately 8,680 person-hours of opportunistic survey effort. In total, we detected two amphibian and 26 reptile species in our study area, including one species classified as Globally Vulnerable by the IUCN. -

ABSTRACT The Shedao pit-viper (Gloydius shedaoensis) exhibits an extreme sedentary lifestyle. The island KEYWORDS species exclusively feeds on migratory birds during migratory seasons and experiences prolonged hibernation Genetic and aestivation period each year (up to eight months). The sedentary strategy reduces energy expenditure, but adaptations may trigger a series of adverse effects and the snakes have likely evolved genetic modifications to alleviate these transcriptome effects. To investigate the genetic adaptations, we sequenced and compared the transcriptomes of the Shedao extreme pit-viper and its closest mainland relative, the black eyebrow pit-viper (G. intermedius). The Shedao pit-viper sedentary life revealed a low rate of molecular evolution compared to its mainland relative, which is possibly associated with Gloydius metabolic suppression. Signals of positive selection were detected in two genes related to antithrombin shedaoensis (SERPINC1) and muscle atrophy (AARS).
