New method to detect impact of sea level rise

University of Adelaide scientists have developed a new simple, inexpensive and fast method to analyse sulfur isotopes, which can be used to help investigate chemical changes in environments such as oceans, and freshwater rivers and lakes.
Published in Talanta, the research opens up potential for new environmental applications of the method, such as tracing the effect of sea level rise, including detection of seawater intrusion into freshwater systems.
“Sulfur isotopes can tell us a great deal about Earth cycles both now and in the past,” said lead author PhD student Emily Leyden from the University of Adelaide’s School of Biological Sciences.
“What we re doing is a little bit different, we re going to be sequencing individual chromosomes, so we re narrowing it down,” she said. There is growing evidence differences in DNA structure play an important role in determining other reproductive traits in birds, she said. “Our research will use new and established techniques to explore the genetic basis of early hatching failure in kākāpō. “We believe this knowledge will transform the way we manage endangered species.”
