Causes and consequences of personalities in microtine rodents
LANTOVÁ, Petra
This thesis focuses on individually specific differences in behavioural strategies, personalities, with two microtine rodents (Microtus arvalis and M. oeconomus) as study species. The work evaluates methodology necessary to reveal and measure consistent individual differences in behaviour, identifies possible proximate and ultimate mechanisms behind the existence of individual behavioural variability, and describes some ecological, evolutionary and behavioural consequences of personalities.
Food selection in Microtus arvalis: the role of plant functional traits
LANTOVÁ, Petra
Foraging by captive common voles (Microtus arvalis) was evaluated by measuring the biomass of plant species consumed in a vivaria experiment and by re-analysing of already published data on plant selection. The experiment showed that foraging was strongly plant species-specific, while data re-analysis indicated the traits plant guild and life span as the best predictors for dietary selection, i.e., voles would eat more grasses and/or legumes than forbs. The study suggests that the voles usually consume grasses in the field because grasses are abundant and readily available, but prefer protein-rich forbs when possible.
