9th IsoEcol Conference 2014 – on the Applications of Stable Isotope Techniques to Ecological Studies


I welcome you this morning to this 9th International Conference for the applications of stable Isotope techniques in ecological studies or as you call it IsoEcol which to me sounded like a terrible virus but I am sure its not. So welcome to our campus on a beautiful winters day and I do hope that you enjoy the next few days while you are here with all your talks. I had a quick look at your programme. It looks very very interesting and I am very pleased to have people from many countries and different organisations here to discuss applications of techniques and development of techniques because I am a very strong believer in new methods and techniques for driving scientific advances. I am going to begin with this slide here which for this audience really needs no explanation. This is an approach that we have used for decades where we analyse the isotopic composition of an organism to get some idea of its trophic position. We can write a simple equation the isotopic composition of the predator is equal to the isotopic composition to the prey plus some tropic discrimination factor. My name is Dr Caroline Kurle and I am a professor at the University of California in San Diego and in my lab we study forging ecology of vertebrates and that just means we want to find out what animals eat and why that matters for their environment and for the ecology in which they live and so we have many projects in my lab including looking at aspects of sea turtle forging ecology We look at sea turtles in the pacific ocean Our main tool is to use stable isotope analysis of animal tissues to try and figure out where they go to reconstruct their migration patterns and reconstruct what they have been eating. Hi its a great honour for me to give a talk here First of all I would like to thank the Science organising Committee. I was funded for about 10 years long for a project on analysis of isotopomers I concentrated on two analytical technologies one is a isotope ratio mass spectrometer. The other is tunable dial laser system at that moment just near infrared spectroscopy we can distinguish between carbon 13 and deuterium both just nearly much difference so high resolution is necessary. My name is Ana Hacohen-Domene I am from Guatamala but I am doing my Phd in Mexico. My PhD research is about whale sharks and manta ray in the Mexican Carribean and I came to Perth to present my research to the IsoEcol Conference which is a very important Stable Isotope Conference globally. Basically what I’ve been doing I sampled whale shark and manta ray in three different aggregation sites and what I have seen so far is that during the whole period of the study the stable isotope hasn’t changed which is good we also haven’t seen any sexual segregation on the stable isotope data and basically whale sharks and manta rays are feeding in same area they are sharing resources in the area Thank you for coming after the field trip and I am really delighted to be here to talk about my favourite topic in the World and I thank the organisers very much for allowing me to do that Hopefully by the end of the talk you’ll see that there has been some little bit of a revolution on In plant physiology. I learned from all your trophic level talks that there has been a lovely revolution going on with using compound specific measurements to look at trophic levels and I was really excited to see that and I hope I can get you guys as excited about whats happening in Plant Physiology with lasers. My name is Trent Marwick. I come from Albany down on the south coast. I began my PhD at KU Leuver in Belgium in 2010 and that took me to Africa where we studied the river encycling of subtropical and tropical river basins. A lot of these river basins there is very little data that’s come out of these basins previously and so we are trying to fill this gap. Rivers play a key role in linking the terrestrial and the oceanic carbon cycles and so its important to understand the processes and the mineralisation and the transport of carbon from terrestrial to oceanic and how this links in to global carbon budgets. Hi I am Cat I am doing a PhD based at the British Antarctic Survey in the UK. I am really grateful to the organising committee of IsoEcol for giving me the opportunity to present these findings. The Conference has been wonderful I have learned a lot so thanks My name is Alex Wyatt I am a Research Fellow from the University of Tokyo. This is my fourth IsoEcol and its a really great opportunity to see research from different fields and different perspectives. We’re hoping to welcome everyone to Tokyo in 2016 for the 10th IsoEcol and I hope we can do as good a job as the organisers have done here in Perth. It was my great pleasure and honour to organise the IsoEco Conference here in Perth at the University of Western Australia We had more than 120 oral and poster presentations covering each single aspect of ecology from deep oceans to City centres. I trust that all participants enjoyed the Conference and returned home refreshed and full of research ideas. Please join us for the next IsoEcol Conference this time in Japan in 2016
