Abstract: This dissertation presents studies on the use of medetomidine, ketamine, and atipamezole for sedating and immobilizing mammals in captivity. The species studies were markhor (Capra falconeri megaceros), snow leopard (Panthera uncia), and blue fox (Alopex lagopus). The objectives of the study were to investigate the effects of the drugs, to compare the efficacy of the drugs, and to establish useful dose levels. Tables, charts, and graphs complement the text. Six papers on which the thesis is based are appended.

Abstract: Animal-borne tracking devices have generated a wealth of new knowledge, allowing us to better understand, manage and conserve species. Fitting such tracking devices requires that animals are captured and often chemically immobilized. Such procedures cause stress and involve the risk of injuries and loss of life even in healthy individuals. For telemetry studies to be justifiable, it is vital that capture operations are planned and executed in an efficient and ethical way. Project objectives must be clearly articulated to address well-defined knowledge gaps, and studies designed to maximize the probability of achieving those goals. We provide guidelines for how to plan, design, and implement telemetry studies with a special emphasis on snow leopards that are typically captured using foot snares. We also describe the necessary steps to ensure that captures are conducted safely, and with minimal stress to animals.
