Developmental research on interspecies relationship and the conservation of black bears and brown bears inhabiting far East Russia

Research grant

Project Description

Black bears and brown bears co-habit the Russian maritime province and as it is rare to investigate the interspecies relationship - conducting this research was difficult due to the harsh natural environment and political situation. This research is in collaboration with the Russian Academy of Sciences, utilizing various analytical techniques now possible due to technological innovation to conduct the world's first research in the Sikhote-Alin reserve conservation region. This research is positioned as the beginning for the conservation of other large mammal species that are in danger of extinction in this region.
