Observations on a red deer (Cervus elaphus) in the province of Drenthe, the Netherlands, during the winter of 2018-2019


Abstract: Red deer (Cervus elaphus) are rare in the Dutch province of Drenthe. Most observations in the past decades were found to be linked to escapes or illegal introductions. In all of those cases, the animals were shot, in accordance with the policy of the province. This article describes a red deer of wild origin, wintering south of Assen in the period December 2018 - May 2019. Intensive surveillance of tracks, combined with camera trapping and analysis of DNA from droppings was conducted to study its home range, behaviour and origin.

Molecular identification of sei whales (Balaenoptera borealis) from the Netherlands


Sei whale (Balaenoptera borealis) is a very rare species in the North Sea. The remains of four whales identified as sei whales, originating from the Netherlands, are preserved in the zoological collection of Naturalis Biodiversity Center, Leiden, the Netherlands. A single bone in the Naturalis collection, found on the Dogger Bank just outside Dutch waters, was also identified as sei whale.
