Beginning in 1984, Eric Dinerstein led a team directly responsible for the recovery of the greater one-horned rhinoceros in the Royal Chitwan National Park in Nepal, where the population had once declined to as few as 100 rhinos. The Return of the Unicorns is an account of what it takes to save endangered large mammals. In its pages, Dinerstein outlines the multifaceted recovery program-structured around targeted fieldwork and scientific research, effective protective measures, habitat planning and management, public-awareness campaigns, economic incentives to promote local guardianship, and bold, uncompromising leadership-that brought these extraordinary animals back from the brink of extinction. In an age when scientists must also become politicians, educators, fund-raisers, and activists to safeguard the subjects that they study, Dinerstein's inspiring story offers a successful model for large-mammal conservation that can be applied throughout Asia and across the globe.

The world's rhinoceroses face extinction because their horns are regarded as extremely valuable. Cunningham and Berger spent 3 years in the Namib desert studying Africa's last sizable group of rhinos, and struggling to find a way to conserve them.

L’hypoxie, secondaire à la dépression respiratoire induite par l’étorphine, des rhinocéros est le problème majeur rencontré durant leur anesthésie. Il existe différentes manières d’y pallier. Certaines jouent sur des paramètres extra-pulmonaires comme l’acidose via le positionnement, la consommation en oxygène via la diminution des tremblements ou encore la tachycardie et l’hypertension via l’utilisation de molécules. De plus, l’expérimentation de différents protocoles anesthésiants utilisés dans un boma ou sur le terrain, permettent également de diminuer les effets de cet état hypoxique. Les résultats actuels sont prometteurs et permettent déjà une immobilisation relativement sûre des rhinocéros africains. Cependant, d’autres recherches devraient permettre d’affiner les protocoles et d’anticiper au mieux les besoins du terrain.
