Group efforts are focused on several fields, from queen quality to molecular work related to breeding.

Availabilty of resources and colony density

We show that both availability of resources and colony density define the mass gain of the colonies during the flow and consequently limit the beekeepers' income. Colony density was calculated as a number of colonies over the resource unit. Work was done in collaboration with dr Milan Kobal from University of Ljubljana and published in the Forest Ecology and Management.

Queen quality paramaters

There are several parameters which presumably describe the quality of the honey bee queens. Among them is a queen body mass, which is probably the easiest to monitor and the most accessible to the consumer. We pooled anatomical, physiological, pathological and rearing parametrs and used the state-of-the-art machine learning to elucidate those parameters that contribute most to the queens' body mass. Work was published in Apidologie.
