Numbers of giraffes are declining rapidly in their native habitat. As giraffe research and conservation efforts increase, the demand for more complete measures of the impact of conservation interventions and the effects of captive environments on animal health and welfare have risen. We compared the ability of six different enzyme immunoassays to quantify changes in fecal glucocorticoid metabolites (FGM) resulting from three sources: adrenocorticotropic hormone stimulation test, transport, and time of day that samples were collected.Two male giraffes underwent ACTH injections; all six assays detected FGM increases following injection for Giraffe 1, while only three assays detected FGM increases following injection for Giraffe 2. Consistent with other ruminant species, the two 11-oxoetiocholanolone assays (one for 11,17-dioxoandrostanes and the other for 3,11-oxo metabolites) measured the most pronounced and prolonged elevation of FGM, while an assay for 3,11-diol detected peaks of smaller magnitude and duration. Both of the 11-oxoetiocholanolone assays detected significant FGM increases after transport in Giraffes 3-7, and preliminary data suggest FGM detected by the assay for 11,17-dioxoandrostanes may differ across time of day.We conclude the assay for 11,17-dioxoandrostanes is the most sensitive assay tested for FGM in giraffes and the assay for FGM with a 5-3-ol-11-one structure is also effective. 11-oxoetiocholanolone enzyme immunoassays have now been demonstrated to be successful in a wide variety of ruminant species, providing indirect evidence that 5-reduction may be a common metabolic pathway for glucocorticoids in ruminants. As FGM peaks were detected in at least some giraffes using all assays tested, giraffes appear to excrete a wide variety of different FGM. The assays validated here will provide a valuable tool for research on the health, welfare, and conservation of giraffes.

The author describes diseases in lemurs, which occurred in the last ten years at Tierpark Berlin. After a short introduction of the importance of lemur husbandry and breeding in zoological gardens a review of the following diseases is given: periarticular hyperostosis in black lemurs, acute alkaloid intoxication in black lemurs, amoebiasis in ruffed lemurs and obesity in mongoose lemurs. Clinical symptoms, diagnosis, therapy and post mortem findings are explained in detail. © 2014 .

The leopard Panthera pardus is widely distributed across Africa and Asia; however, there is a gap in its natural distribution in Southeast Asia, where it occurs on the mainland and on Java but not on the interjacent island of Sumatra. Several scenarios have been proposed to explain this distribution gap. Here, we complemented an existing dataset of 68 leopard mtDNA sequences from Africa and Asia with mtDNA sequences (NADH5 + ctrl, 724 bp) from 19 Javan leopards, and hindcasted leopard distribution to the Pleistocene to gain further insights into the evolutionary history of the Javan leopard. Our data confirmed that Javan leopards are evolutionarily distinct from other Asian leopards, and that they have been present on Java since the Middle Pleistocene. Species distribution projections suggest that Java was likely colonized via a Malaya-Java land bridge that by-passed Sumatra, as suitable conditions for leopards during Pleistocene glacial periods were restricted to northern and western Sumatra. As fossil evidence supports the presence of leopards on Sumatra at the beginning of the Late Pleistocene, our projections are consistent with a scenario involving the extinction of leopards on Sumatra as a consequence of the Toba super volcanic eruption (~74 kya). The impact of this eruption was minor on Java, suggesting that leopards managed to survive here. Currently, only a few hundred leopards still live in the wild and only about 50 are managed in captivity. Therefore, this unique and distinctive subspecies requires urgent, concerted conservation efforts, integrating in situ and ex situ conservation management activities in a One Plan Approach to species conservation management. © 2016 The Zoological Society of London

Berlin Tierpark has a breeding female of the dark form of Steller's Sea Eagle Haliaeetus pelagicus ("niger"). This is the first known specimen for about half a century and the first evidence that it is not a subspecies but just a colour phase. © 2010 Dt. Ornithologen-Gesellschaft e.V.

A group of eight (2.6) White-lipped deer (Cervus albirostris) and four (1.3) fawns, born in 2010, kept in Tierpark Berlin were observed with focal point at circadian behavioural pattern, mother-child-interaction and the ontogeny of behaviour.The circadian rhythm of the animals proved to be bimodal and in its activity periods clearly synchronized with daily routine in the zoo. The animals showed different types of behaviours concerning metabolism (47%), comfort and resting (25%), movement (11%) and other behaviour (17%). The parallels between the distribution of behaviour and spatial use during the day point to an obvious relevance of different shaped enclosure areas to the behaviour. Calves of White-lipped d (" Ablieger" ). Initially the fawns entered the enclosure trough the fence four to five times a day, exclusively for suckling. Until the fourth week of life their distribution of behaviour and their daily rhythm were well-adjusted to that of the adults. Despite of an age difference up to 17 days, the hiding period of all four fawns ended more or less at the same point of time; in case of the oldest fawn after 6, in case of the youngest fawn already after 31/2 weeks of life. This indicates a synchronisation of the ontogeny of behaviour between older fawns and younger ones living with each other. In the process of dietary change from milk to solid food this synchronization was also to be seen. During the first two weeks the fawns were almost exclusively in contact with their mothers, but with time the bonding between the four fawns got stronger. The young affect each other in their development of behaviour. Above-mentioned traits of weaning in mammals point to the onset of weaning in the observed animals at three to four weeks of live.All in all the behavioural development of White-lipped deer obviously depends on physiological needs and abilities as well as social environment. © 2011.

Tierpark Berlin is keeping Steller's Sea Eagles since 1959 continuously without any breeding success till 2009. There was one egg laid in 1962 only. In 2001 we received a female from Tiergarten Nuremberg. At seven years of age this bird has moulted into its adult plumage this being all dark brown apart from the white tail. This is the only known present living specimen of this dark morph and the first known for several decades. As the parents show the normal coloured plumage this is the first evidence that niger doesn't exist as a subspecies but is a dark colour phase of pelagicus only. The dark coloured female was breeding with a normal coloured male in 2009 and one offspring was parent reared for the first time at Tierpark Berlin. © 2010.
