Ecophysiology and population biology of animals

We are dealing with the biological structure of populations of small and underground mammals with a particular focus on ethological, physiological and genetic differences between individuals. For example, we pay attention to both aspects, the variability associated with the adaptive values ​​of the selected parameters and the variability that is the result of personality traits or behavioral syndromes – successful strategies at the intra-group level. These strategies can have a strong genetic basis, but they can be also obtained in pre- and postnatal periods. Knowledge of the quality of individuals (behavioral, physiological, genetic) is very useful to us for studying, for example, the role of the Earth’s magnetic field in orientation and navigation, as well as assessing anthropogenic influences ranging from the disturbing effects of radiofrequency fields to habitat fragmentation, which is one of the key issues in nature protection. From this point of view, we have several exemplary species (European ground squirrel – Spermophilus citellus, garden dormouse – Eliomys quercinus), in which we examined the structure of the populations in the Czech Republic, but also in the context of the whole distribution and how the degree of isolation leads to inbred depression – the reduction in viability of individuals in their subpopulations. This research focus brings knowledge immediately applicable in conservation practice.
