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.

Abstract: There is a general concern amongst ecologists about the apparent decline of small mustelids in The Netherlands over the past decades. However, little is known about their actual historic and present numbers. To better understand their ecology and the cause of the decline more research into these small predators is a necessity.

Abstract: On 24 April 2019 the remains of an otter (Lutra lutra) were found on the verge of a road on the island of Sula (Norway). About 95% of skeletal elements were collected. Inspection revealed several recently broken ribs and vertebrae, that may have led to the death of this individual. This paper describes the previously existing skeletal lesions, discusses the most probable cause of death, and attempts to estimate the age of the specimen.
