“…We might expect that in water voles body condition is state-dependent. Evsikov et al (2008) found a clear link between body condition and reproductive characteristics of females, but more data are needed to elucidate whether in our case predated individuals where skewed towards one reproductive state.…”

a b s t r a c tUsing field methods that provide unbiased estimates of predation risk is challenging for medium and small sized prey. We conducted this study in a simple predator-prey system (Sleneset archipelago, northern Norway) where eagle owls Bubo bubo depend on water vole Arvicola amphibius and other predators are absent, and we tested the prediction that substandard individuals (i.e. with lower body condition) would be exposed to higher predation risk. In summer 2007-2009 we capture-mark-recaptured water voles with passive integrated transponder tags inserted by injection under the skin of the neck. We then searched and scanned the study area for passive transponders in eagle owl pellets and compared the body condition of predated and unknown fate individuals by means of logistic regression models. Substandard water voles had a higher probability of being predated by eagle owl, suggesting that voles in compromised condition were more vulnerable to predation. Therefore natural selection may be at work also through avian ambush predators.

“…In turn, body weight and body condition may impact litter size (Evsikov et al, 2008). The complexity of factors determining body condition may explain why residuals from the linear regression explain only a small part of the variation in the body condition index in small mammals (Schulte-Hostedde et al, 2005).…”

Investigations into small mammals within the territory of a breeding colony of great cormorants (Phalacrocorax carbo sinensis), carried out in 2011-2014 near Juodkrantė (West Lithuania), demonstrated the colony's impact on the dominant rodent, yellow-necked mouse (Apodemus flavicollis). The age and sex structure of the sampled mice (n = 432), along with body weight, body condition index, and residuals from the linear regression, were used to analyse data from five zones of the colony and the surrounding forest. We found that in the most active zones of the cormorant colony, the age structure of the population was tilted towards a prevalence of juveniles, while sex structure was towards a prevalence of males (P < 0.0001). Despite males being significantly longer in body and heavier, body condition index was the same in both sexes. The effect of the zone of the colony was confirmed for body weight and its residuals; body length and body condition index (main effects ANOVA) were negative in the zones where cormorants were nesting actively.

The contribution of the maternal environment (gestational weight gain, month of birth, and litter size) to the formation and realization of the reproductive potential of adjacent European water vole genera tions has been studied for years in the natural population and in captivity. The accumulation of body fat and other reserves during pregnancy plays an essential role in the regulation of reproductive processes. Realization of the reproductive potential of females, growth rate, and the sexual maturation of the offspring depends on the ability of the mothers to properly utilize the energy reserves of their body both during pregnancy and at the next stage of the reproduction cycle, lactation.
