Similarity of locomotor personality trait within parents improves their reproduction in the common vole (Microtus arvalis) under laboratory conditions

Popis výsledku v původním jazyce

In the last decade, the personality traits of the common vole (Microtus arvalis) have been well described. However, to date, the mechanisms by which they are maintained in vole populations have received only marginal attention. Inspired by a study of mound-building mice, the present study focused on the possible role of assortative mating based on similar personality traits within the breeding pairs. Under laboratory conditions, seven behavioural parameters were evaluated in 63 individuals (34 males, 29 females) during three successive open field (OF) tests: total distance moved, ratio between the inner area distance/total distance moved, grooming, jumping, locomotion, scanning, and latency to the first movement. Five observed behavioural parameters based on duration were reduced to two synthetic parameters using principal component analysis (PCA). Using GLMM, we calculated for each individual the intercepts (considered personality trait) and slopes of random effects in the total distance, ratio of distances, and the scores of two PCA ordination axes. The effect of within-pair differences in intercepts (personality traits similarity) for each tested variable on the number of offspring was then tested using the function for zero-inflated models. A significant negative correlation was obtained only for the personality trait similarity of the total distance moved. This means that the smaller the personality trait difference (higher similarity) of overcoming a distance (locomotor ability) between the parents led to an increased number of offspring. The results are discussed in terms of the parents&apos; fitness strategies under different population densities.
