“…Generally, during the 20th century, zoos transformed from assembled collections to internationally managed insurance populations [21]. Establishing and maintaining sustainable ex situ populations has required inter-institutional and international cooperation, which has been started since the 1970s and more intensively since the turn of the 1980s and 1990s [22]-on the European level, the European Endangered Species Programmes (EEP; now called EAZA Ex situ Programmes) since 1985 and the European Community Association of Zoos and Aquaria (ECAZA), founded in 1988 and transformed into the European Association of Zoos and Aquaria (EAZA) in 1992 [23]. Local and atypical individuals and common taxa have been replaced (as a part of ex situ conservation) by meaningful taxonomic units and endangered taxa, and single individuals were replaced by appropriate social and breeding groups [7,24,25].…”

Zoos represent a social construct, whose form is influenced by societal development. During the 20th and at the beginning of the 21st century, they have been transformed from assembled collections to internationally managed insurance (ex situ) populations, and these transformations required some changes in taxa numbers and composition. Previous studies have already identified the trend of reducing the number of taxa kept in zoos worldwide. The aim of the present study is to verify this trend in Europe in more detail and therefore to identify the changes in taxa richness and mammalian taxa richness from 1959 to 2016 in the same set of 67 European zoos while considering their opening period (before 1900 and 1900–1960) and location with respect to the former Iron Curtain (Eastern vs. Western Bloc). There was no significant decrease in taxa richness; on the contrary, there was a significant increase in taxa richness for the former Eastern Bloc zoos. There was a significant decrease in mammalian taxa richness for zoos opened before 1900 and those of the former Western Bloc. These results demonstrate that mammalian taxa have declined in numbers to some extent and that the decline mostly concerns older zoos and those that have historically reached a different stage of development. This suggests that European zoos have not been subject to trends uniformly and should apply different and appropriate strategies when facing future (not only conservation) challenges.

Asian hornbills have limited ex situ breeding success, yet these species are some of the most threatened of birds, in need of managed breeding programs. To optimize breeding and increase the sustainability of such populations, it is necessary to assess and improve their husbandry and welfare. Evidence to improve reproduction can be gathered through global husbandry surveys. A survey was sent out to all European Association of Zoos and Aquaria and Association of Zoos and Aquarium holders of the wreathed hornbill (Rhyticeros undulatus) and Papuan hornbill (R. plicatus) to determine predictors for ex situ breeding success. This research found that pairs that have spent more years together (p = .016) and that adding additional proteins to the diet (p = .006) are two significant predictors of breeding success for wreathed‐ and Papuan hornbill pairs. This paper found a general trend that successful hornbill pairs prefer nest boxes that are situated outside (p = .054). The behaviors of calling to each other and sitting in close proximity showed a general trend and were observed more frequently in successful pairs and, therefore, could be good indicators of bonded pairs. We recommend that ex situ institutions allow their hornbill pairs time to form strong bonds, and that pair compatibility is monitored regularly to ensure that such interactions are positive and not consistently negative. An increase in the percentage of dietary proteins, prior and during the breeding season appears to stimulate pairs to breed. If the management and husbandry alterations presented in this study are implemented, the sustainability of Rhyticeros hornbill populations may be enhanced.
