What are the family relationships between bears?

This project concerns genetics at the individual level, f. ex. how bears in a certain area are related to each other. By following marked females for many years we have found out that some females are very successful mothers and some do not succeed at all. It was also observed that some males are together with many more females during mating season than other males. By analysing the nuclear DNA of the cubs from known mothers we can determine paternity of those cubs.
When it is determined which males and females are most successful for reproduction, it is possible to find out how f. ex. the bears’ relationships, weight, age and environment can influence individual reproductive success.
