Diederik, a seven-year-old male rhinoceros, died suddenly on Wednesday morning at Wildlands Adventure Zoo Emmen. An examination found that he had suffered a ruptured aorta.
Keepers had separated him for observation, testing and care from Tuesday afternoon after noticing unusual behaviour. He remains described as being missed by the zoo.

Wildlands Adventure Zoo in Emmen and the Dutch Food and Consumer Product Safety Authority (NVWA) are surveying a tropical greenhouse for the Asian bark beetle Euwallacea fornicatus, which was found there two years ago. The invasive beetle bores into plants and can spread fungi that damage branches or entire trees. The park aims to establish the extent and locations of the infestation, prevent its spread and determine how to control it. Teams are inspecting mapped sections of the 23-metre-high, 16,000-square-metre greenhouse using aerial work platforms, binoculars and flashlights. Affected plants are marked and may in some cases be pruned rather than removed. Fieldwork is due to continue until 13 November, after which the data will be analysed before conclusions are drawn.
