“…This could be an important limiting factor for reproductive mature females. Similar results were reported by Bujalska (1985Bujalska ( , 1990 in populations of Clethrionomys glareolus. In this case, overwintering female removal in experimental enclosures should accelerate the onset of reproductive activity relative to control enclosures.…”

We tested the hypothesis that adult overwintering Calomys venustus inhibit maturation and reproduction in young-of-the-year from the first cohort. The study was carried out in four 0.25-ha enclosures (two control and two experimental), each situated on natural pasture. This study was conducted between August 1997 and March 1999 and had two parts: removal of overwintering male (ROM) and removal of overwintering female (ROF). For the ROM treatment overwintering males were removed immediately after the first cohort of juveniles were born, in the ROF treatment overwintering females were removed after the first cohort were weaned.Weekly censuses were taken for three successive days over 6 weeks. The sexual maturation and reproductive condition of juveniles were compared between treatments (overwintering male or female removal) using repeated-measures anova. The repeated measures factor was the age of juveniles. Removal of overwintering males and females did not affect sexual maturation of juveniles, however, overwintering males influenced the onset of reproductive activity of juvenile females at the beginning of the breeding period.

“…Adding to our final model for the open grid a term for the interaction between female and winter leads to a significant estimate with a negative slope (−0.354, 95% confidence limits: −0.550; −0.158) confirming that the emigration of females during winter may indeed be the cause of the lower apparent survival from November to February. This may furthermore be due to the establishment of territories for females which occurs one or two months before reproduction starts (Bujalska 1990); once the habitat is saturated and all territories occupied, additional females do not have any other choice than to disperse. Because many more females emigrated than males we do not believe this emigration could have been caused by a sink effect (Pulliam 1988) related to the removal study in half of the open grid.…”

Survival in fluctuating bank vole populations: seasonal and yearly variations

For most organisms, both within‐year (i.e. seasonal) and between‐year variations in demography are important components in shaping the population dynamic patterns observed on a multiannual scale. These two sources of variation have, however, rarely been studied simultaneously. Most of the recent work on small rodent population dynamics, for example, has focused on between‐year variation. Densities of seed‐ and fruit‐eating rodents, such as the bank vole (Clethrionomys glareolus), are in particular known to have between‐year variation related to seed crop production. Here we report on the analysis of a long‐term (1976–1982) capture‐mark‐recapture (CMR) study of the bank vole in Belgium. The study was done on two grids, an open and a fenced grid. As part of the CMR statistical analysis, we propose a general modelling approach which allows for a detailed understanding of the relative importance of seasonal and between‐year variation in survival. We demonstrate that most of the seasonal variation corresponds to a lower apparent survival in spring compared to the rest of the year. During winter, apparent survival was lower on the open grid than on the fenced grid. Dispersal is therefore concluded to be an important determinant of the seasonal pattern. The between‐year variation in survival is largely attributable to variation in seed crops, and is comparable in magnitude to the seasonal variation.

“…In Northern Europe, bank voles live mainly in coniferous forests. In contrast to that, in western Europe, the preferred habitats are broadleaved oak and beech forests as well as densely mixed forests with abundant herb and undergrowth layers (Bujalska 1990). Vole populations underlie cycles in population dynamics, which seem to be more prominent in Fennoscandia than in Western Europe (Olsson et al 2002).…”

Emergence of hantavirus in South Germany: rodents, climate and human infections

et al. 2008

Human hantavirus (serotype Puumala) infections are prevalent throughout Europe. The bank vole is the main reservoir of the Puumala virus (PUUV). Between 2001 and 2006, the annual incidences in Germany ranged from 0.1 to 0.5 per 100,000 inhabitants. About half of the cases were reported from the state of Baden-Württemberg (BW) in southwest Germany. In 2007, 1,089 PUUV infections were reported from BW. This reflects an incidence of 10.1:100,000, which is more than 11 times higher than the mean incidence of the previous 6 years. Spatial analysis highlights incidences up to 90:100,000 in the most affected district. The winter season 2006/2007 showed an all time high in reported mean temperature. The previous summer and autumn led to a beech mast year, resulting in favourable feed conditions for bank voles in the winter season 2006/2007. The causes of the observed increase in PUUV infections in 2007 cannot be restricted to known cycles in the bank vole population. Favourable feed conditions, a mild winter and an early onset of spring may have influenced bank vole population size as well as human exposure to infectious rodent excretions. Further epidemiologic studies are necessary to better understand the interaction between environmental factors, occurrence of Puumala virus in bank voles and the risk for human disease.
