No place to hide: Limited forest cover hampers the availability of suitable habitat for lynx in the Netherlands


In Europe, centuries-long of overharvesting and hunting of large herbivores and carnivores has resulted in extinctions of large mammals, such as the lynx (Lynx lynx). With the expansion of lynx distributions via recolonisation and reintroduction programmes, it is possible that the lynx will again recolonise the Netherlands. This study identified the most important predictors for lynx habitat suitability in the Netherlands and areas in the Netherlands where the ecological requirements of the lynx are met.

Damage to dykes and levees in the Netherlands is extensive and increases with muskrat (Ondatra zibethicus) density


The muskrat (Ondatra zibethicus) is an invasive species in the Netherlands. Its burrowing habits are alleged to threaten the integrity of the extensive water control infrastructure, posing a public safety hazard in this densely populated, low-lying country. A national control program currently traps and kills tens of thousands of muskrats each year. The costs (annually about € 35M) as well as concerns raised by animal welfare groups have raised questions about whether the control program could be improved, and even whether it is necessary at all.

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.

Lutra 62(1)_Thomassen_Editorial_2019


One of my favourite natural history books is “Monster of God”, by David Quammen, subtitled “The Man-Eating Predator in the Jungles of History and the Mind”. It tells the story of man’s relationship with big, fierce animals, the ones that can kill and eat us. To illustrate his story, Quammen draws on four examples, three of them mammals (Romanian bears, Russian tigers and Indian lions). He describes the threats to these species, the conflicts that arise where humans and large predators live near one another and the efforts of conservationists.

Re-mating in otter (Lutra lutra)

After the first observation of three morulas in the uterus of an otter (Lutra lutra) (Broekhuizen et al. 2004) a second observation of three morulas, together with three early-stage blastocysts, was made in April 2005. In the light of the short period of delayed implantation of blastocysts in the mucous membrane of the uterus we discuss the probability of this indicating re-mating and compared the evidence with the more frequent occurrence of superfoetation in the American mink (Mustela vison).
