Pregnancy success in wild Norwegian lemming, Lemmus lemmus, and root voles, Microtus oeconomus, was monitored by recording the occurrence and condition of copulatory plugs, embryos, and mammae in ear-tagged females, which were recaptured several times throughout the summer of 1981 at Finse, Norway. Both populations increased and peaked in density during this period and evidence of pregnancy failure was found in several young, nulliparous females of both species. Similar observations have been reported in several other microtine species and the results are discussed in relation to (i) infertility of immature females, (ii) pregnancy block caused by unfamiliar males, and (iii) other stress related phenomena.

Abstract The hypothesis that predation is the cause of the regular small rodent population oscillations observed in boreal and Arctic regions has long been debated. Within this hypothesis, it is proposed that the most likely predators to cause these destabilizing effects are sedentary specialists, with small mustelids being possible candidates. One such case would be the highly specialized least weasel (Mustela nivalis) driving the Norwegian lemming (Lemmus lemmus) cycle in Fennoscandia. These predators are often elusive and therefore distribution data can only be based on field signs, which is problematic when various mustelid species are sympatric, such as weasels and stoats (Mustela erminea). Here we present the results of using mustelid faeces in predated winter lemming nests to correctly identify the predator and thus discern which species exerts the strongest predation pressure on lemming winter populations. Samples were obtained during different phases in the lemming cycle, spanning 6 years, to account for different prey densities. Faecal mitochondrial DNA extraction and amplification of a 400-bp fragment was successful in 92/114 samples (81%); the sequencing of these samples proved that most predation occurrences (83%) could be attributed to the least weasel. These findings support the hypothesis that weasels in particular show high specificity in predation and could therefore be candidates to driving the lemming cycle in this area. We conclude that DNA analysis of faecal remains around predated nests can be a useful tool for further investigations concerning predator–prey interactions in the tundra.
