Quantitative scores for 4 behavioural patterns, especially those of an antagonistic nature, were recorded from wild individual of Mus musculus mutsculus Linnaeus, 1758 living in semi-confinement in an outdoor enclosure divided into four pens. The enclosure was "permeable", in that mice were able to move between pens and between the enclosure and the outside. The population was monitored by the capture-mark-recapture method. In the spring of 1988 and 1989 the behaviour of mice trapped in the enclosure was studied in unisexual encounters in a neutral arena. There were no significant differences in scores for behaviour in relation to the degree of spatial separation of the places of capture of individuals paired together (except in the number of attempts to escape noted for females in 1989 and the total activity noted for males in 1988). Males and females did not differ significantly in scores for aggressive behaviour, but mice were more aggressive and more active in 1989 when the population in the enclosure was smaller, than in 1988, when it was larger.

This paper reviews field evidence suggesting that periodic temporary population irruptions of feral house mice Mus musculus in New Zealand have a substantial effect on the reproductive success of stoats Mustela erminea Linnaeus, 1758. Stoats born during the summer of a peak in numbers of mice are more numerous and have higher fecundity (ovulation rate) but lower productivity (independent offspring per female) and shorter longevity than those born when mice are not abundant. This reversed silver-spoon effect is apparently correlated with intense competition for food within a much larger than usual cohort of young stoats. However, both stoats and mice are introduced in New Zealand, so it is possible that these effects are not natural. The question could be resolved by data demonstrating similar cohort effects in stoats in the northern hemisphere, living in areas with fluctuating vole populations and limited alternative prey.

Skulls of 892 house mice of five species (Mus Linnaeus, 1758), collected from 136 localities across Europe and Morocco, were studied. The analysis revealed that variations in size affected most of the characters considered, indicating a reed to size-adjust- the data. M. domesticus was morphologically the most variable of all the European mice yet this variability was not consistent with the distribution of subspecies domesticus and brevirostris, The population from Albania was distinct within the M. domesticus samples, resembling M. musculus in overall size. In M. musculus, a W-E gradient of size was found in some variables, especially in females, and a sex dimorphism appeared also in populations from western parts of its range. Among 619 mice from 66 samples across the Czech and Slovak Republics and western Ukraine, but not from populations from western Bohemia, only M. musculus was substantiated. In spite of the fact that M. spicilegus and M. macedonicus are genetically and morphologically very close, as many as 9 variables (both untransformed and size-adjusted) proved to be different between the two species while M. spretus was found to be morphologically intermediate.

Maximum cold-induced rate of food consumption in cold-acclimated laboratory house mice Mus domesticus averaged 10.4 g/day in females (body mass before cold exposure = 25.2 g) and 10.7 g/day in males (body mass = 31.7 g); corresponding maximum rates of energy assimilation were 139 kJ/day in females and 144 kJ/day in males. The traits were highly repeatable: the intraclass correlation coefficient for three trials at -10°C was greater than 0.7 for absolute values and greater than 0.6 for values independent of the initial body mass (residuals from ANCOVA). The estimate of repeatability of the mass-independent traits depends on which estimate of body mass (initial or after cold exposure) is used as a covariate in the regression or ANCOVA model. We conclude that the values of maximum cold-induced food consumption and energy assimilation are reliable estimates of the performance of individuals under a specific set of environmental conditions (low ambient temperature, but not limited access to food) and hence may be subject to phenatypic natural or artificial selection.

The parasite fauna (protozoa, helminths and insects) of the two most widespread Murinae rodents in El Hierro (Canary Islands, Spain), the black rat (Rattus rattus) and the house mouse (Mus musculus domesticus) was studied. Faunistic, ecological, ecotoxicological data, as well as information on the biology of some nematode parasites of R. rattus are provided. The present work is unprecedented in the Canary Islands, and provides the first data on the parasite biodiversity in Murinae from the archipelago. Concerning to parasitofaunas stands out: a) impoverishment of biodiversity of helminths respect of which have the same hosts in other islands; b) increasing the number of species of Siphonaptera, even compared with flea species that parasitize the same hosts from continental biotopes.

Three morphological characters were used to depict the position of the hybrid zone between two species of house mice, M. musculus Linnaeus, 1758 and M. domesticus Schwarz et Schwarz, 1943, across a vast area covering countries of the former Yugoslavia, Albania, Bulgaria and Greece. Quantitative approach based on a morphological index (MI), resembling the hybrid index widely used in allozyme-based genetic studies, was used. The zone crosses Slovenia south of the Sava River, and then follows the Dinaric Mts to Montenegro and northern Albania. Contrary to many previously published results, the zone was found to run parallel with northern borders of Albania and the former Yugoslavian Macedonia, about 150 km north of the Greek border, thus giving its course rather "shallow" appearance at this part of the Balkan Peninsula.

House mice Mus musculus domesticus (Schwartz and Schwartz, 1943) from Orkney are closely related on the basis of mandible morphology and allozyme variation. In three of the twenty islands where house mice occur populations have diverged from the standard 2n = 40 karyotype through fixation of Robertsonian (Rb) chromosomal mutations. Mice from Westray island carry 36 chromosomes and share one Rb fusion with those from Eday and Faray (2n = 34; 2n = 34-36). These islands are geographically very close to each other and to islands carrying standard mice. Behavioural and ecophysiological analyses were performed on the three chromosomally divergent populations of mice as well as on two nearby standard populations (Sanday and Papa-Westray). The aim of the study was to assess -whether divergences attributable to chromosomal changes occur, and to discuss whether behavioural divergences may explain the non-mixing of karyotypes. The study does not reveal any divergence between islands attributable to karyotype or habitat differences. The non-blending of the different karyotypes present in Orkney is discussed with reference to history of colonisation, human behaviour, and the consequences of site saturation. Particular characteristics displayed by the different island-populations suggest that in the near future the present pattern of karyotype variation observed in Orkney could change.
