Conservation Biology Research
Wildlife ecology: the basic science for conservation
Our group studies ecology and conservation of wildlife. Main
study subjects are vertebrate animals such as mammals
including deer, fox, raccoon dog, raccoon, monkey, vole and bat,
and amphibians including salamander, toad and
frog. Through field work and experimental
study, we investigate
(1) role of wildlife in forest ecosystem,
(2) adaptive meaning and evolution of animal behavior and life history,
(3) impacts of natural and artificial environmental changes on animal behavior and population,
(4) population genetics of wildlife at large spatial scales,
(5) intra- and inter-specific interactions,
and (6) population and community dynamics.
Animals including amphibians, birds and mammals are our main subjects.
Animal survey using infrared camera
Using automotive infrared camera, we investigate distribution and behavior of mammals. Brown bears captured in Tomakomai Experimental Forest can be seen with the following video clips.
Our group conduct several field experimental projects.
Example of study theme
As one of our researches, adaptive strategies in behavior and life history of animals are studied. For example, Rana pirica frog tadpoles plastically develop their body in the presence of predatory salamander larvae (Hynobius retardatus) to prevent them from being swallowed by the predator. We explore evolutionary processes and ecological consequences of the defensive strategy. Rana pirica tadpoles with non-defensive “typical” morph and with defensive “bulgy” morph can be seen with the following video clips.
