All of the presentations at IAA16 were of the very highest quality and the organisers of IAA16 extend their thanks to the Judges (Alastair Richardson, Cath- erine Souty-Grosset, and Clive Jones) who were faced with a very difficult task indeed given the quality of all the presentations.

Friday, the final ½ day of the symposium, commenced with morning tea (at 10 AM) and the days activities included the IAA general assembly, welcom- ing Catherine Souty-Grossest as the new IAA President (and handing over the interim IAA fossil crayfish- kangaroo ―thing‖), some very kind words from from words kind very some ―thing‖), kangaroo Mar- tin Moore to the IAA16 team.

Ministry of the Environment of Japan has successfully designated the genus Astacus, Pacifastacus leniusculus, Orconectes rusticus and the genus Cherax as invasive alien species under the Invasive Alien Species Act. Live import, translocation and/or release of these organisms is now strictly regulated under the IAS Act. http://www.env.go.jp/nature/intro/r_yunyu_e.pdf Our institute (National Institute for Environ- mental Studies), a stand-alone institute of the Minis- try of the Environment of Japan, is trying to educate the general public not to import or translocate the invasive alien species or other alien species. Because the IAS Act is a new law, many people still don't know which organisms are the listed species and what the regulations are. As a part of an exhibition at Tsukuba Expo Center (Tsukuba, Japan), I am going to present a poster con- cerning the hazards of alien species on ecosystems, and exhibit photos of representative invasive alien species (including both animals and plants). As a crayfish specialist, I would like to have photos of the invasive alien crayfish, in particular.

Starr is fast becoming a paragon of contemporary Australian art, both in Australia and around the world. With successful exhibitions around Australia as well as in New York and Singapore, she is carving a niche for her- self, with an instantly recognizable and thoroughly original style. Her work explores the warmth and passion of life as an artist, and Starr captures in paint what the camera seeks to fix in a moment of time. Starr creates works that become contemporary icons. Her subject matter is both familiar and universal in appeal. The lush layered surfaces are worked with fast-saturated color and include her signature calligraphic line that traces time and energy. Her individual works have become highly collectable.

Since 2001, the Madison researchers, aided by a small army of undergraduate students and the Wisconsin Department of Natural Resources , have succeeded in significantly reducing the population of rusty crayfish in Sparkling Lake through a program of intensive trapping targeting the largest crayfish and manipulating fishing regulations to favor the small- mouth and rock bass that dine on juvenile crayfish. The two-pronged attack, says Carpenter, has yielded very promising results. ―It seems to be working. The aquatic plants are are plants aquatic The working. be to seems ―It back.
