A Primer on Reptiles and Amphibians What others are saying about the Primer... "I hope it gets, because it deserves, wide attention. It is a must-read for anyone, child or adult, interested in or just curious about herps or nature." —Dr. Brian Crother, Professor of Bio- logical Sciences, Southeastern Louisiana University; Chair of the Committee On Standard English And Scientific Names, Society for the Study of Amphibians and Reptiles “A Primer on Reptiles & Amphibians” looks like an outstanding educational product. I can tell from my first look that Micha has done an excellent job of covering a variety of herp top- ics everyone wonders about." —Dr. J. Whitfield "Whit" Gibbons, Professor Emeritus of Ecology, University of Georgia; renowned author of numerous books and hundreds of papers on herpetology "A truly extraordinary and exceptional website and a most remarkable effort to put this amount of herpetological information together. I commend Micha’s thorough dedication to the teaching and welfare of herps.” —Dr. Stan Trauth, Emeritus Professor of Zoology, Arkansas State University; Past President (2012-2013), Herpetologists’ League "I'd be really excited to see this distributed widely because to me it reads as a lot more ac- cessible than most of what's out there, and that's really important for reaching new audi- ences and changing behaviors." —Dr. Andrew Durso, Technical and Scientific Publications Editor at Max Planck Institute for Biogeochemistry; Author of Life is Short, but Snakes are Long "This book is going to make a difference!" —Dr. Harry W. Greene; Professor Emeritus; Stephen H. Weiss Presidential Fellow; Curator of Herpetology, Cornell University Museum of Vertebrates Read more reviews at LearmAboutCritters.org/primer Sierra Nevada Ensatina photo by Chad M.

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage.

  • Failure to Launch? the Influence of Limb Autotomy on the Escape Behavior of a Semiaquatic Grasshopper Paroxya Atlantica
    Behavioral Ecology doi:10.1093/beheco/arr045 Advance Access publication 4 May 2011 Original Article Failure to launch? The influence of limb autotomy on the escape behavior of a semiaquatic grasshopper Paroxya atlantica (Acrididae) Philip W. Batemana,b,c and Patricia A. Flemingb aDepartment of Zoology and Entomology, University of Pretoria, Pretoria 0002, South Africa, bSchool of Veterinary and Biomedical Sciences, Murdoch University, Murdoch, WA 6150, Australia, and cArchbold Biological Station, Lake Placid, PO Box 2057, Lake Placid, FL 33862, USA Downloaded from Autotomy is an extreme escape tactic where an animal sheds an appendage to escape predation. Many species alter their behavior postautotomy to compensate for this loss. We examined the escape behavior in the field of a semiaquatic grasshopper (Paroxya atlantica) that could escape either by flight and landing in vegetation or flight and landing in water and swimming to safety. We predicted that animals missing a hind limb would be more reactive (i.e., have longer flight initiation distances; FID) and would beheco.oxfordjournals.org prefer to escape to vegetation rather than to water as loss of a limb is likely to reduce swimming ability. However, our predictions were not supported. FID in autotomized animals was not different from that in intact animals. Furthermore, although autotom- ized grasshoppers paused more often and swam slower than intact individuals, autotomized grasshoppers more often escaped to water, reaching it via shorter flights that were lateral to the approach of the observer (intact grasshoppers more often flew directly away from the observer). We also noted differences in behavior before disturbance: Autotomised animals perched lower on emergent vegetation than did intact ones, presumably in readiness for escape via water, and also showed a greater likelihood to at Murdoch University on June 19, 2011 hide (squirreling) from the approaching observer prior to launch into flight.

  • Field Notes from Africa
    Field Notes from Africa by Geoff Hammerson, November 2012 Africa! Few place names are evocative on so many levels and for such diverse reasons. Africa hosts Earth’s most spectacular megafauna, and the southern part of the continent, though temperate rather than tropical, has an extraordinarily rich and unique flora. Africa is the “cradle of humankind” and home to our closest living primate relatives. Indigenous peoples in arid southern Africa have learned to live in one of Earth’s most extreme environments. For early sea-going explorers, Africa was both an obstacle and a port of call, and later the continent proved to be a treasure-trove of diamonds, gold, and other natural resources. Sadly, Africa is also a land of human starvation, deadly disease, and genocide, and grotesque slaughter of wildlife to satisfy the superstitions and greed of people on other continents. It was a target for slave traders and a prize for imperialists. Until as recently as 1994, South Africa was a nation where basic human rights and opportunities were Our experience was greatly enhanced by the truly apportioned according to the melanin content of exceptional quality and efforts of our South African one’s skin. Africa’s exploitative and racist history guide, Patrick Cardwell, who was frequently and has made it a cauldron of political and social superbly assisted behind the scenes by Marie- turmoil. Given this mixture of alluring and Louise Cardwell. Patrick’s knowledge and repugnant characteristics, many potential visitors experience repeatedly put us in the right place at to Africa first pause and carefully consider the just the right time.

Do NOT cut the wound, apply substances to the wound or use a tourniquet. Do NOT remove jeans or shirt as any movement will assist the venom to enter the blood stream. KEEP THE VICTIM STILL. 1. Apply a broad pressure bandage over the bite site as soon as possible. 2. Keep the limb still. The bandage should be as tight as you would bind a sprained ankle. 3. Extend the bandage down to the fingers or toes then up the leg as high as possible. (For a bite on the hand or forearm bind up to the elbow). 4. Apply a splint if possible, to immobilise the limb. 5. Bind it firmly to as much of the limb as possible. (Use a sling for an arm injury). Bring transport to the victim where possible or carry them to transportation. Transport the victim to the nearest hospital. Please Print this page off and put it up on the wall in your snake room. 2 There is some serious occupational health risks involved in keeping venomous snakes. All risk can be eliminated if kept clean and in the correct lockable enclosures with only the risk of handling left in play.

  • EFFECTS of LATITUDE, SEASON, ELEVATION, and MICROHABITAT on FIELD BODY TEMPERATURES of NEOTROPICAL and TEMPERATE ZONE Salamandersl
    Ecology, 63(6), 1982, pp. 1657-1664 © 1982 by the Ecological Society of America EFFECTS OF LATITUDE, SEASON, ELEVATION, AND MICROHABITAT ON FIELD BODY TEMPERATURES OF NEOTROPICAL AND TEMPERATE ZONE SALAMANDERSl MARTIN E. FEDER Department ofAnatomy and Committee on Evolutionary Biology, The University of Chicago, Chicago, Illinois 60637 USA, and Museum of Vertebrate Zoology, University of California, Berkeley, California 94720 USA AND JAMES F. LYNCH Chesapeake Bay Center for Environmental Studies, Smithsonian Institution, P.O. Box 28, Edgewater, Maryland 21037 USA, and Museum of Vertebrate Zoology, University of California, Berkeley, California 94720 USA Abstract. We analyzed field body temperatures of neotropical salamanders (Feder et al. 1982b) to examine existing generalizations about salamander thermal ecology, which have been based almost entirely upon data for temperate zone species. Our findings can be summarized as follows: 1) Behavioral thermoregulation in the field is evidently uncommon among the vast majority of tropical and temperate salamander species. Body temperatures of tropical salamanders closely parallel seasonal and altitudinal changes in the thermal environment. 2) Body temperatures of salamanders show a complex relationship with latitude. Temperate zone species experience lower minimum temperatures than neotropical salamanders, but there are no consistent latitudinal trends in maximum body temperatures. Tropical plethodontids and ambysto­ matids show similar rates of decline in mean body temperature with increasing elevation, but am­ bystomatid temperatures are significantly warmer than plethodontid temperatures at the same ele­ vation. 3) Variation in body temperature is greater seasonally for temperate salamanders than tropical salamanders. At a given time or locality, however, variation in field body temperature among members of a population is similar for tropical and temperate salamanders.

  • The Herpetofauna of the Cubango, Cuito, and Lower Cuando River Catchments of South-Eastern Angola
    Official journal website: Amphibian & Reptile Conservation amphibian-reptile-conservation.org 10(2) [Special Section]: 6–36 (e126). The herpetofauna of the Cubango, Cuito, and lower Cuando river catchments of south-eastern Angola 1,2,*Werner Conradie, 2Roger Bills, and 1,3William R. Branch 1Port Elizabeth Museum (Bayworld), P.O. Box 13147, Humewood 6013, SOUTH AFRICA 2South African Institute for Aquatic Bio- diversity, P/Bag 1015, Grahamstown 6140, SOUTH AFRICA 3Research Associate, Department of Zoology, P O Box 77000, Nelson Mandela Metropolitan University, Port Elizabeth 6031, SOUTH AFRICA Abstract.—Angola’s herpetofauna has been neglected for many years, but recent surveys have revealed unknown diversity and a consequent increase in the number of species recorded for the country. Most historical Angola surveys focused on the north-eastern and south-western parts of the country, with the south-east, now comprising the Kuando-Kubango Province, neglected. To address this gap a series of rapid biodiversity surveys of the upper Cubango-Okavango basin were conducted from 2012‒2015. This report presents the results of these surveys, together with a herpetological checklist of current and historical records for the Angolan drainage of the Cubango, Cuito, and Cuando Rivers. In summary 111 species are known from the region, comprising 38 snakes, 32 lizards, five chelonians, a single crocodile and 34 amphibians. The Cubango is the most western catchment and has the greatest herpetofaunal diversity (54 species). This is a reflection of both its easier access, and thus greatest number of historical records, and also the greater habitat and topographical diversity associated with the rocky headwaters.

We hypothesized that the Sacramento, Smith, Klamath, and Rogue River watersheds would represent distinct genetic populations based on prior ecological results, which suggest that Black Salamanders avoid high elevations such as the ridges that separate watersheds. Our mitochondrial results revealed two major lineages, one in the Sacramento River watershed, and another containing the Klamath, Smith, and Rogue River watersheds.
