In this study we systematically examined species-specific exploration behaviour and behavioural acclimatisation of a black rhino Diceros bicornis founder group post-translocation. The study was carried out in a fenced region, approximately 350 km2 in size and directly adjacent to Etosha National Park in Namibia. Rhinos were radio-tracked and movement data were complemented by detailed habitat descriptions at the centres of rhino activity with vegetation plot sampling. Rhinos used both geological formations of the study area: Otavi dolomite and Etosha calcrete substrate. The latter was dominated by Acacia spp. due to former land use for livestock farming. The size of total and seasonal home ranges and core areas, as well as home range establishment patterns and habitat use, are highly variable among individual rhinos. Home ranges of most individuals from our study are among the largest recorded for the species. We found age class specific patterns of home range establishment, typical mating and social behaviour, seasonal changes of home range and core area size, and clear shifts in spatial behaviour over time. The results provide our best estimate to date for the natural exploration behaviour and behavioural acclimatisation of black rhinos in a semi-arid savannah ecosystem. © 2010 by Walter de Gruyter.


Breeding polar bears has a long tradition in the Zoo am Meer, the "Zoo at the Sea" in Bremerhaven. In the years between 1935 and 1974 three female bears gave birth to 32 cubs and 19 of them were successfully raised. In the following years many attempts to tie in with this tradition failed. Bad constructional conditions and disadvantageous animal pairings were the main reasons for the missing breeding success. After completely reconstructing the polar bear enclosure in the year 2002, as well as extending the breeding area with an additional smaller breeding cave in 2012 and pairing male Lloyd and female Valeska in 2013 a new polar bear birth and upbringing could be experienced after 40 years.

Already at the opening of the Zoo am Meer in 1928 the Northern Gannets (Morus bassanus), whose main range is located off the east coast of Scotland, were part of the animal collection of the small zoo at the Weser river in Bremerhaven. The first successful breeding at the Zoo am Meer and thus also the first time in captivity at all, succeeded in 1988. Presumably the breeding was only successful because of the exceeding of a critical group size that allows certain group dynamic behaviours. After a complete renovation of the Zoo am Meer in 2004, a new phase of breeding with 16 animals began. Already in 2005 there was the first offspring and since then a total of 30 chicks hatched. Consistently it happens that animals that shelter their chicks are distracted by one bird and other birds steal and eat the chick. Plaster eggs for couples without oviposition or the removal of individuals provide relief during this critical period. © 2016
