Available in PDF, EPUB and Kindle. Book excerpt: Three species of New Zealand native frogs (Leiopelma archeyi, L. hochstetteri, and L. pakeka) have been held in captivity in various institutions since 2000 as part of a programme to maintain and breed these threatened species. Following the death of a large number of these captive frogs, the Department of Conservation Native Frog Recovery Group decided that an investigation was needed to determine the cause. In this mortality study, we obtained data from captive populations to analyse mortality rates and causes of death for 252 wild-caught Leiopelma spp. These were held in captivity at the University of Canterbury and later transferred to other institutions between 2000 and 2006. Leiopelma archeyi and L. hochstetteri had similar overall average mortality but different yearly mortality patterns, whereas L. pakeka had much lower overall mortality. The major cause of death for L. archeyi and L. hochstetteri was bacterial infection, which was thought to be induced by a combination of husbandry factors, but mainly from oversterilising the substrate. Consequently, Auckland Zoo instigated a change in management, whereby soil was only heated to a temperature and for a length of time that was just sufficient to kill amphibian chytrid. New disease syndromes (skin blisters and muscle deterioration (rhabdomyolysis)) were also detected. Knowledge of disease is an important component of captive husbandry, so that healthy breeding populations can be maintained and we can gain an insight into diseases that may be affecting free-living populations. It is recommended that the staff at each institution undertake a review of all captive mortalities and report back to the Native Frog Recovery Group on an annual basis, so that any husbandry or disease issues that have arisen can be identified quickly.

Download or read book Status of Conservation and Decline of Amphibians written by Harold Heatwole and published by CSIRO PUBLISHING. This book was released on 2018-06 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibians are among the most threatened groups of animals on earth. In part due to their highly permeable skin, amphibians are highly sensitive to environmental changes and pollution and provide an early-warning system of deteriorating environmental conditions. The more we learn about the impact of environmental changes on amphibians, the better we as humans will be able to arrest their demise, and our own. Status of Conservation and Decline of Amphibians brings together the current knowledge on the status of the unique frogs of Australia, New Zealand, and the Pacific. Although geographically proximate, each region presents unique challenges and opportunities in amphibian research and conservation. This book contributes to an understanding of the current conservation status of the amphibians of each region, aims to stimulate research into halting amphibian declines, and provides a better foundation for making conservation decisions. It is an invaluable reference for environmental and governmental agencies, researchers, policy-makers involved with biodiversity conservation, and the interested public.

Book excerpt: “A huge, beautiful compendium of 600 frogs from around the world, from the famed poison-arrow variety on up to the intriguingly named plaintive rain frog.” —Wired With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin’s Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature’s most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size—including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world. “If you are a serious (and I mean serious) fan of the frog, you are in for a real treat.” —Boing Boing

Also included are the introduced Cane Toad and nine ‘stowaway’ species that have arrived in Australia. Each species account includes details of size, status, distribution, habitat, behaviour and advertisement call.

The introductory section of the book covers frog biology and habitats and includes notes on families and genera.
Download or read book The Tuatara Lizards and Frogs of New Zealand written by Richard Sharell and published by . This book was released on 1966 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a new kind of nature book. Designed for readers of all ages, it is an introduction in combined text and superb photographs to particular group of creatures - in this volume the colourful reptiles and amphibians of New Zealand. The strangest member of this group, an animal found nowhere else on earth, is the tuatara. The tuatara looks like a lizard, but is is not one. It is the only survivor from the age of giant reptiles - the bronchosaurs, the dinosaurs - and it has remained with us for 135 million years practically unchanged: a living example of ancestral reptiles from which we have evolved. No wonder that it should feature so prominently in Maori art and folklore. Mr. Sharell has for many years studied and photographed the tuatara and its distant cousins, New Zealadn's lizards and frogs, and in this book he gives us the fruit of his work. It is at once an authoritative and richly illustrated handbook, and a striking testimony to his conviction that nature study cannot - or should not - be divorced from an appreciation of nature's beauty.
