New observations of the ‘extinct’ Barbary sheep Ammotragus lervia ornata in Egypt.

Oryx 36 (3): 301-304.

Abstract:

The Barbary sheep or aoudad Ammotragus lervia is widely distributed in the mountains of the Sahara and North Africa. The 2000 IUCN Red List assessment of the Egyptian subspecies A. l. ornata categorized this taxon as Extinct in the Wild. We present new evidence, collected during 1997–2000, that this subspecies is extant in both the extreme south-east and south-west of Egypt, and reassess the status of captive aoudad in Egypt. We recommend that the category of A. l. ornata on the IUCN Red List be changed to Critically Endangered, that conservation of wild aoudad in Egypt be prioritized, and that the subspecific status of both the wild and be reassessed.

VARGAS, A. et al. (2008)

The Iberian lynx Lynx pardinus Conservation Breeding Program

Int. Zoo Yb.(2008)42:190–198
DOI:10.1111/j.1748-1090.2007.00036.x

The Iberian Lynx Conservation Breeding Program follows a multidisciplinary approach, integrated within the National Strategy for the Conservation of the Iberian lynx, which is carried out in cooperation with national, regional and international institutions. The main goals ofthe ex situ conservation programme are to:

  1. maintain agenetically and demographically managed captive population;
  2. create new Iberian lynx Lynx pardinus free-ranging populations through re-introduction.

To achieve the first goal, the Conservation Breeding Program aims to maintain 85% of the genetic diversity presently found in the wild for the next 30 years. This requires developing and maintaining 60–70 Iberian lynx as breeding stock. Growth projections indicate that the ex situ programme should achieve such a population target by the year 2010. Once this goal is reached, re-introduction efforts could begin. Thus, currentex situ efforts focus on producing psychologically and physically sound captive-born individuals. To achieve this goal, we use management and research techniques that rely on multidisciplinary input and knowledge generated on species’ life history, behaviour, nutrition, veterinary and health aspects, genetics, reproductive physiology, endocrinology and ecology. Particularly important is adapting our husbandry schemes based on research data to promote natural behaviours in captivity (hunting, territoriality, social interactions) and a stress-free environment that is conducive to natural reproduction.

REHÁK, I. (2020)

The great turtle rescue.

ZOOQUARIA 107:  22-23.

Aus dem Inhalt: 

On 11 December 2001, during a joint operation of the Customs Ship Search and Cargo Command and the Agriculture Fisheries and Conservation Department,  about 10,000 live South East Asiatic turtles were seized in Hong Kong. The shipment, originally destined for the Chinese food market, had an estimated market value of $3.2 million. The conservation and scientific value of the confiscated animals, as well as the ethical aspects of the situation, were enormous, and incalculable in monetary terms. Turtles were placed at Kadoorie Farm and Botanic Garden in Hong Kong. It was an incredible job to take care of such a quantity of mostly damaged, wounded and ill turtles. The wider international cooperation proved to be essential in reducing at least in part the suffering of the turtles. EAZA’s swift reaction and the international rescue that followed were exemplary. The superb cooperation between the Kadoorie Farm and Botanic Garden, TSA and EAZA – namely the EAZA Executive Office, ARTAG, Rotterdam Zoo and 26 other zoos in 11 countries – resulted in the successful import of 988 turtles (285 Cuora amboinensis, 126 Orlitia borneensis, 283 Heosemys spinosa, 90 Heosemys grandis, 204 Siebenrockiells crassicollis) and their consequent housing in individual zoos. During the rescue operation, which attracted a huge amount of publicity and media coverage, EAZA demonstrated its ability to carry out a complicated international operation with speed and efficiency, and we can be rightly proud of that.

U.S. FISH AND WILDLIFE SERVICE SW REGION (2013)

Thick-billed Parrot (Rhynchopsitta pachyrhyncha) Recovery Plan Addendum.

122 Seiten.

Recovery Strategy:

The thick-billed parrot has been absent from the U.S. for over 70 years and now only occurs in Mexico.  Thus, the focus of recovery conservation actions should occur inMexico.  Since the mid-1990s, conservation organizations and the Mexican government have been implementing conservation actions focused on research, monitoring, and protection of key breeding areas.  Furthermore, as part of a federal initiative, Mexico convened a group of parrot experts and in 2009 published a recovery plan (the PACE) addressing both the maroon-fronted and thick-billed parrots.  The focus of the PACE (CONANP 2009) is on extant populations of the thick-billed parrot; it does not address thick-billed parrot historical records or historical range in the U.S. Therefore, our approach in this Addendum to the PACE is to:

  • Summarize information on thick-billed parrot’s historical occurrence in the U.S.;
  • Synthesize or reference information (when feasible) from the PACE to formulaterecovery planning components as are required by the ESA;
  • Incorporate supplemental information received from Mexico and U.S. partners since publication of the PACE;
  • Identify broad actions necessary to address conservation of the species within its U.S. historical range;
  • Identify partnerships and opportunities to facilitate recovery of extant populations.

Antelope Conservation ä From Diadnosis to Action.

Conservation Science and Practice 16: 1-376.

Wiley Blackwell / Zoological Society of London. ISBN: 978-1-118-40957-2.

Beschreibung:

Antelopes constitute a fundamental part of ecosystems throughout Africa and Asia where they act as habitat architects, dispersers of seeds, and prey for large carnivores. The fascication they hold in the human mind is evident from prehistoric rock paintings and ancient Egyptian art to today's wildlife documentaries and popularity in zoos. In recent years, however, the spectacular herds of the past have been decimated or extripated over wide areas in the wilds, and urgent conservation action is needed to preserve this world heritage for generations to come.

As the first book dedicated to antelope conservation, this volume sets out to diagnose the causes of the drastic declines in antelope biodiversity and on this basis identify the most effective points of action. In doing so, the book covers central issues in the current conservation debate, especially related to the management of overexploitation, habitat fragmentation, disease transmission, climate change, populations genetics, and reintroductions. The contributions are authored by world-leading experts in the field, and the book is a useful resource to conservation scientists and practitioners, researchers, and students in related disciplines as well as interested lay people.

Giraffenschutz in Uganda

Schutz der Rothschildgiraffe im Kidepo Nationalpark

Zoo und Zoostiftung Berlin

AFR 2016 4 rothschild kidepo
Rothschildgiraffen im Kidepo Nationalpark © Care for Karamoja
Die bedrohte Rothschildgiraffe (Giraffa camelopardalis rothschildi) ist natürlicherweise weltweit nur noch in zwei Verbreitungsgebieten zu finden: Im Murchison Falls Nationalpark sowie im Kidepo Valley Nationalpark (beide Uganda). Während die mit etwa 1.000 Tieren deutlich größere Population im Murchison Falls Nationalpark teils von einer bislang nicht genauer untersuchten Hautkrankheit befallen ist, ist die Population im Kidepo Nationalpark unbelastet und daher von besonderer Wichtigkeit. Das Projekt „Care for Karamoja“, das vom Zoo Santa Barbara (USA) ins Leben gerufen wurde, hat es sich zur Aufgabe gemacht, diese sehr kleine Population von ca. 54 Tieren zu schützen.

Da der Kidepo-Nationalpark im Norden an den politisch extrem instabilen und von Armut gekennzeichneten Südsudan grenzt ist der Hauptbedrohungsfaktor für diese kleine Population die illegale Jagd für die Gewinnung von Fleisch und Fellen. Außerhalb des Parks gibt es wegen der dichten Besiedlung und intensiven Landnutzung keine Giraffen - und kaum anderes Großwild - mehr. Daher wurde mit der Uganda Wildlife Authority sowie dem Uganda Wildlife Education Centre (UWEC) ein Schutzprogramm erarbeitet. Dies beinhaltet in erster Linie die Unterstützung der Ranger im Kidepo NP, die dringend mit professionellem Equipment ausgestattet werden müssen. Weiterhin soll die lokale Bevölkerung langfristig für den Artenschutz sensibilisiert werden, indem u.a. lokalen Schulklassen der Besuch des Nationalparks ermöglicht wird. Der Zoo Berlin hält Rothschildgiraffen und unterstützt als größter europäischer Partner dieses Schutzprojekt, zu dem auch Zoos in den USA beitragen.

Case report 7 - Montserrat mountain chicken (Leptodactylus fallax): Breeding, reintroduction and other conservation measures.

In: DOLLINGER, P. ed. (2007) Amphibien brauchen unsere Hilfe. Verhandlungsbericht des Amphiobienkurses gemeinsam organisiert mit den Zooverbänden im deutschsprachigen Raum. Chemnitz, 27.-30. Juni 2007. WAZA, Bern: S. 118.

Zusammenfassung der Powerpoint-Präsentation:

The mountain chicken is one of the most threatened amphibians in the world. Its range historically included up to seven, Eastern Caribbean islands but the species is now confined to the islands of Dominica and Montserrat. A combination of hunting, introduced predators and habitat loss was thought to have caused the extirpation of the species from the islands of Guadeloupe, St Kitts and Martinique around 500 years ago.

The wild populations on Montserrat were severely affected when the Soufriere Hills volcano erupted after a 350-year period of dormancy in 1995 and destroyed a significant part of its range. The species distribution on Montserrat has fallen to less than 17km2 and the increasingly toxic, acidified environment may have reduced juvenile survivorship and reproduction. The current status of the Montserrat population is unknown after renewed volcanic eruptions on 13th July 2003 covered the island in a thick layer of ash.  Lately, 2005 and 2006 severe impact of the volcano affected the island again.

Chytrid fungus has been found on the populations of Mountain chickens in Dominica.  Although no cases of chytrid disease have been reported in Montserrat, this island may also be at risk.  If Montserrat is unaffected, frog populations on the island may be the last hope for the survival of the species. 

In collaboration with the Government of Montserrat, Durrell Wildlife has initiated captive breeding of the species, and has also undertaken fieldwork to understand the animal in the wild.

We investigated the presence of disease on mountain chickens and the sympatric species within the Centre Hills in Montserrat. No chytrid or exposure to ranavirus was detected.  We draw tentative conclusions about disease threats to the Montserrat mountain chicken population, and present preliminary recommendations for safeguarding this species.
A major biodiversity assessment effort led by Durrell, the Royal Society for the Protection of Birds (RSPB) and the Montserrat Government has been recently been completed   and is aiding the management and declaration of the Centre Hills as a national park.

Conservation breeding of the Northern river terrapin Batagur baska at the Vienna Zoo, Austria, and in Bangladesh.

International Zoo Yearbook 49: 39–41. London Zoological Society. ISSN 0074-9664. DOI: 10.1111/izy.12070.

Abstract:

Wild populations of the Northern river terrapin Batagur baska have been decimated to such an extent that the species can be considered as ecologically extinct. Harvesting and habitat reduction are the main reasons for the drastic demise of B. baska, which formerly inhabited rivers and estuaries in East India, Bangladesh and Myanmar. A cooperative in situ and ex situ conservation project was established to secure the survival of this large river terrapin. In 2010, at Vienna Zoo, Austria, the first two captive-bred juveniles of the project hatched and presented an opportunity to call attention to this Critically Endangered species. With combined efforts a breeding population has been assembled in Bangladesh's Bhawal National Park and 84 juveniles have been reared in the past 2 years. Project-Batagur demonstrates how zoos can play a key role in sustainable long-term conservation of threatened species.

The Pygmy Hippopotamus Choeropsis liberiensis (Morton, 1849): Bringing to Light Research Priorities for the Largely Forgotten, Smaller Hippo Species.

Das Zwergflusspferd Choeropsis liberiensis (Morton, 1849): Überblick der Literatur und wichtige Forschungsthemen für das oft vergessene kleinere Flusspferd.

Zool. Garten N.F. 84 (2015): 234-265. ISSN 0044-5169.

Abstract:

An endangered species, the pygmy hippo (Choeropsis liberiensis Morton, 1849) has been housed in captivity since the early 1900s, but systematic, prospective research and peer-reviewed literature remain limited in comparison to other IUCN-listed, charismatic mega fauna. There are just over 350 animals in the ex situ population worldwide, so it is an uncommon resident in zoological collections compared to the larger, ‘common’ or Nile hippo (Hippopotamus amphibius).

Most published information for the pygmy hippo constitutes descriptive accounts of first-hand experiences in various zoological institutions. Here we review, analyze and provide a synthesis of the pertinent literature, aiming to identify and prioritize focal research topics for optimizing ex situ management. The pygmy hippo is continually reported to breed well and thus long-term survival of the species, at least in captivity, is assumed, although we identify several reasons to exercise caution.

Further, we demonstrate that the common perception amongst zoological institutions that the pygmy hippo is easy to manage and experiences limited health and husbandry issues is erroneous. Specific issues affecting the captive population with potential negative implications for long-term sustainability include polycystic kidney disease (PKD), a female-biased sex ratio, obesity, a high neonatal mortality rate, and failure of many breeding pairs to reproduce. We identify several research priorities to help address these concerns, and how the resulting information can be applied to improve management, health and welfare of pygmy hippos in captivity.

Captive Management of the Chilean Pudu (Pudu pudu Molina 1782).

Deer Specialist Group Newsletter 27 (April 2015): 67-73-
ISSN 2312-4644

Abstract:

The Southern Pudu has long been classified as Vulnerable by Red List™, however  some  successful breeding programs are ongoing for this species. Since the introduction of the International Studbook and the  European  conservation  breeding  program  for Pudu  pudu, a  stable  population  with  more  than  100 individuals  has  been  kept  at  zoos  in  Europe,  North  and  South  America.  Not  a  lot  is  known  about  this small deer and we will update soma data on the captive management of this species, including general husbandry, diet and reproduction. The new data is mostly very similar to that published by Schürer and Sliwa (2002) apart from the average life-span which has increased over the years.
