“…Such abundance of food for mustelids cannot easily be matched in New Zealand by introduced species of commensal rodents that have recently invaded unfamiliar forest habitat. Indeed, Raymond et al . (1990) and Vaudry et al .…”

In the Holarctic, predation by mustelids on birds is often linked to population cycles of rodents (especially voles and lemmings) because birds may be buffered against mustelid predation at high rodent densities. By contrast, interguild relationships between introduced mustelids and rodents can have very different consequences for native birds in ecosystems where mustelids have been introduced. Here, we consider the interactions between Stoats Mustela erminea, feral House Mice Mus musculus and native birds in New Zealand beech Nothofagus spp. forests. We conclude that buffering to protect birds from Stoat predation normally fails in these systems, because peak populations of mice in these forests are low by Holarctic standards, and mice usually do not become sufficiently abundant to distract increased numbers of Stoats from preying on birds. However, temporary buffering is possible during rare episodes of extreme mouse abundance.

“…In general, males take a higher proportion of larger prey such as rabbits than do females, which depend to a greater extent on small rodents (King 1989b;McDonald et al 2000b). Observations on captive stoats of both sexes show that females gain more net benefit from hunting voles than do males (Raymond et al 1990). …”

“…The broken line (MJ4) was used for graphing purposes only. MALES FEMALES structure of ermine populations are unstable over the years, presumably due to a combination of variations in annual population turnover and reproductive output (King and Moors 1979), prey supply (Raymond and Bergeron 1982;Vaudry et al 1990;Raymond et al 1990), and (or) parasitic infestations (Weber 1986). Otherwise, the densities observed during this study fell within range of those previously reported for ermine and least weasel in Ontario (Sirnms 1979), England (King 1975a), Switzerland (Debrot and Mermod 1983), and Russia (Heptner et al 1967), despite interdemic variation in ermine body size.…”

Spacing patterns in mammals are influenced by mating systems such as polygyny -promiscuity. Movement parameters were monitored over 3 years in an increasing population of ermine, Mustela erminea cicognanii, in southern Quebec (45"22'N, 71 "51 'W), and the effects of age, sex, breeding status, and annual densities on movements were examined. Residency times (range 24-443 d) were significantly higher in females than in males. Populations were composed of more visiting males than residents and more resident females than visiting females. Adult and juvenile males travelled significantly more than adult females and during the year of highest density than in other years. Males' travel distances significantly decreased and those of females increased during the postbreeding season. Males' home range sizes (range 1 .O-87.4 ha) were significantly larger than those of females during the postbreeding period and over the whole season. Home ranges overlapped only between the sexes. Our study showed little influence of annual variations in population density on spacing patterns. We conclude that (i) movements in Nearctic ermine populations are, at moderate to high population levels, influenced by intraspecific characteristics, and (ii) in view of the similar behavior of Palaearctic and Nearctic ermine, interdemic body size range has little influence on spacing patterns of ermine.RCsumC : La rkpartition spatiale des mammiferes est influencke par le systkme d'appariement, telle la polygynie-promiscuitk.
