Om fokprogramma's succesvol te laten verlopen en daarmee het doel van soortbehoud na te streven, moeten dierentuinen onderling diertransacties uitvoeren. Binnen de transportwerkgroep van de Nederlandse Vereniging voor Dierentuinen is de vraag ontstaan naar een handboek dat geraadpleegd kan worden bij …

Het aantal roofvogels in Nederland is snel toegenomen. Uit een rapport van bureau Ulucus blijkt dat er veel misstanden zijn op het gebied van huisvesting, gedrag en overlijden na wegvliegen/ontsnappen.

This study investigated on which way seabirds, in mixed enclosures, can be provided in nutritional needs in a way that is as close as possible to their natural situation. The main question of research is: “How should the seabirds at Rotterdam Zoo be provided in their nutritional needs in a way that is …

In zoos there is a lack of space for old world monkeys as enclosures become bigger and more naturalistic, because of the advances in enclosure design. A potential solution is housing old world monkey species in mixed species exhibits. The main question to research this potential is: Which of the TAG …

Despite the polar bears’ long history of high popularity in zoo settings, many studies indicate that this wide-ranging species expresses many abnormal repetitive behaviours in captivity, such as stereotypic walking, head swinging and repetitive swimming bouts. This is also the case in the male polar …

The white rhinoceros (Ceratotherium simum) is stated as „near threatened‟ since 2002 by the IUCN. The EAZA rhino collection is not self-sustaining. In addition to a breeding program, EAZA husbandry guidelines are developed in order to share knowledge on best husbandry practise among the European institutions …

Due to improved zoo practices, longevity in zoo animals has increased. In comparison to the wild, many species become much older in captivity. Senescence follows a different path in each species and is therefore hard to generalize towards other species. Insights into the process of senescence in animals …

To be able to keep sustainable populations which are independent from wild populations zoos need to cooperate in collection planning. To aid this cooperation the Taxon Advisory Groups (TAGS) of the European Association of Zoos and Aquaria (EAZA) design Regional Collection Plans (RCPs). These RCPs contain …
