2014 is the 125th year of the International Congress of Zoology (ICZ) and the 10th year of the International Society of Zoological Sciences (ISZS). The International Society of Zoological Sciences (ISZS) will hold the 6th International Symposium of Integrative Zoology: Outlook and Prospectives of Integrative Zoology & Celebrating 125 Years of the International Congress of Zoology and 10 Years of the International Society of Zoological Sciences, 24–25 Nov 2014, at the Institute of Zoology (IOZ), Chinese Academy of Sciences (CAS), Beijing, China. The ICZ has a long history. It began in 1889 at the initiative of the Société Zoologique de France on the occasion of the International Exposition inParis. It provides an opportunity to showcase the interdisciplinary nature of the zoological sciences. In addition, the Congress brings together a wide range of scientists concerned with zoology, as well as zoological pedagogy, paleozoology, ethics and the integration of zoology with other disciplines. The ICZ is held every four years in different locations, usually in conjunction with a national zoological society. The 22nd ICZ will be held in Okinawa, Japan in 2016 and the 23rd,Cape Town, South Africain 2020. The ISZS was established at the 19th ICZ inBeijingin 2004 as an international zoological body charged with organizing the ICZ and providing a global voice for zoologists. The ISZS is a nonpartisan, nonprofit membership-based organization of professionals that aims to: · promote zoology by improving communication between zoologists and zoological organizations; · increase the availability of resources needed to conduct zoological research; · and promote co-ordination, collaboration and co-operation between different fields of zoology. Currently, it remains the only organization that covers all branches of zoological sciences. The core business of ISZS includes organizing the ICZ every four years, publishing Integrative Zoology(INZ), a multidisciplinary scientific journal which is SCI and Medline Indexed, organizing the International Symposia of Integrative Zoology (ISIZ) in non-Congress years, and facilitating international research programs, such as Biological Consequences of Biological Sciences (BCGC). Currently, there are over 100 institutional members, including scientific academies, universities, NGOs, nature reserves, zoos and other professional societies from every continent, as well as more than 1000 individual members, with ISZS.

Both the Symposium and Celebration provide an opportunity to review the history of ICZ, ISZS and INZ, to summarize the progress of global zoology, and to discuss the outlook and prospectives of integrative zoology. We look forward to the participation of zoologists, scientists, guests, students from all over the world, as well as ISZS members, EC & AC members, INZ board members and other invited guests, at this great event and celebration inBeijing.
