Poster

Extinction and speciation are two key processes that contributed to the formation of global patterns of biodiversity.  Extinction is, therefore, a natural process.  On the other hand, increasing human influence upon global ecosystems is accelerating species extinction.  How does extinction occur?  How do natural and anthropogenic factors interact upon extinction? What consequences are to be expected following mass extinction?  These are critical questions from both basic and applied standpoints.

 

The purpose of the conference "The Biology of Extinction 2" was to discuss these questions by following up progress in biological sciences related to the extinction of species since the first OBC “The Biology of Extinction” in 2004.  The goal of this series of conferences was to explore the possibility of forming a new research field of basic biology centered on the theme of extinction.

We invited nine non-Japanese and five Japanese researchers to attend the first OBC conference and they made significant contributions to its success.  In addition, we invited ten new members in order to broaden our perspectives and stimulate discussion.

 

There were two oral sessions, one in the morning and one in the afternoon, on each day of the conference, excepting Wednesday. These sessions constituted seven sets of papers with specific themes, each of which included three or four speakers. Wednesday afternoon was a time for poster presentations.  On Friday morning, eight short talks were given by presenters selected from among the poster presenters.  The quality of all of the posters and short talks was very high.

 

In the seven sessions listed below, we identified some critical progress in our understanding of extinction proneness, the dynamics of extinction, speciation and migration, climatic change effects upon extinction, the role of human psychology upon anthropogenic extinction, and other issues.  After the sessions, we had a general discussion about how extinction biology can be developed and synthesized. All of the participants were enthusiastic about participating in the birth of a new research field.

In conclusion, we believe that the meeting was a successful one.  This third OBC conference provided an opportunity for experts in different branches of biology to meet and interact productively.
