This year’s 0 m event is very special, as we celebrate the 10th ITRS, since 1 its inception in 1990 and host over 190 delegates from 24 countries, making it one of the biggest ITRS’ to date. The 10th ITRS will be hosted by the University of Western Australia through the Oceans Institute and the School of Plant Biology. The organising committee would like to acknowledge the Traditional Owners of the land hosting our conference, the Nyoongar People. We would like to pay 4 1 0 respect to their Elders both past and present and extend 2 y r that respect to other indigenous Australians. a u n a J 7 The overarching theme for the 10th ITRS is Ecological 1 - Transitions. This theme captures the intention to explore 12 T a he li diverse spatial, temporal, environmental and biotic transi- U ra ni ust ver n A tions in temperate reef ecosystems in an inclusive way. The sity of Wester theme also recognizes that a key challenge for the future is linking mechanistic ecology with approaches that address global questions. Our Conference Logo Inside this book you will find a detailed program of the conference, abstracts from all the oral and poster presenta- tions and contact details of all the delegates. Please feel free to come and chat to any of the organising committee if you need information on anything throughout the week. Thank you to our Sponsors! Sincerely, The 10th International Temperate Reefs Symposium, would not be possible without the generous support of our sponsors; Thomas Wernberg, Gary Kendrick, Scott Bennett,.
