Population declines of small mustelids by rodenticide use

I think it may interest you this study:

Alterio, N. (1996). Secondary poisoning of stoats (Mustela erminea), feral ferrets (Mustela furo), and feral house cats (Felis catus) by the anticoagulant poison, brodifacoum. New Zealand Journal of Zoology, 23(4), 331-338.

It seems that in New Zealand anticoagulant rodenticides affect the populations of small mustelids. In this country small mustelids were introduced and the control of their populations is necessary to reduce the impact of predators over native species, that have not evolved in the presence of mammalian carnivores. However the use of anticoagulant rodenticides is also applied in mainland Europe, where these predators are native species and also suffer the consequences of secondary poisoning.

Here I put you some pictures of the footprint tracking tunnels I use to monitor small mustelids, similarly as in this study.
