New research from the University of Adelaide has shown that many of the animal species at risk of extinction in the United States have not made it onto the country’s official Endangered Species Act (ESA) list.
The ESA is one of the best known national lists and arguably the world’s most effective biodiversity protection law. The study – now published in the latest issue of Conservation Letters – has compared the ESA list of endangered species with the world’s leading threatened species list, the International Union for the Conservation of Nature (IUCN) Red List. This comparison showed that approximately 531 American species on the IUCN Red List have not made the ESA protection list.

“The ESA has protected species since its establishment in 1973, and it may have prevented 227 extinctions. However, the implementation of the ESA by successive US governments has been problematic, including poor coverage of imperilled species, inadequate funding, and political intervention,” says study leader Bert Harris, a native of Alabama who is undertaking his PhD with the Environment Institute and School of Earth & Environmental Sciences.
The study was conducted in collaboration with the University of California, Santa Cruz, the National University of Singapore and the University of Göttingen, Germany.

Several Environment Institute Researchers have been involved with a new study which has found that the warming ocean climate is causing seaweed communities, on which fauna survive, to retreat to the brink of the continent and possibly extinction.
The results were published in the latest edition of Current Biology, and Dr Bayden Russell, Dr Fred Gurgel, Professor Corey Bradshaw and Assoc. Professor Sean Connell are among the authors of this paper led by Assistant Professor Thomas Wernberg from The University of Western Australia.

Adam Langman and Gus Nathan from the CET recently published a paper in Experimental Thermal and Fluid Science.
The title of the paper is ‘Influence of a combustion-driven oscillation on global mixing in the flame from a refinery flare’.
An assessment of the influence of strong combustion-driven oscillations on mixing rates and visible radiation in the flame from a full-scale refinery flare is reported. The analysis reveals a consistent picture that the combustion-driven oscillations do not result in a significant change to the global mixing rate, but do increase the visible radiation. This is in contrast to previous investigations, using externally forced jets, where forcing at the preferred mode has been found to increase mixing rates and reduce radiation.
