Brief Description of the short-term Research Project:

“Estimation of invertebrate Population Size based on Movement Patterns”

Pitfall trapping is a standard method for collecting ground-dwelling arthropods but the numbers trapped individuals depend not only on the population density also on the activity of animals, as well as on other factors. Therefore, numbers of trapped individuals did not allow direct estimation of population density but only of activity-density. Different sized animals move and are trapped with different rate, even for same species, because of this when sampling most of insect (except social insects) by method which depends on their activity, size distribution is almost always skewed positively. Animal that moves more will be encountered more often in the traps than less mobile individuals. Size and movement ability is also correlated-larger organisms are able to move on larger distances. Within this project I plan to (1) experimentally estimate movement patterns of different sized individuals (model organism: Tenebrio molitor), (2) using simulation conduct computer experiment of trapping different sized individuals and propose estimation of real population density based on proportion of different sized individuals. Project will show if real population density can be estimated by calibrating sampled data using distribution of body sizes of a sample. Model will be validated experimentally for different population sizes.
