The study, the first of its kind, was published this week online in the British Ecological Society’s prestigious Journal of Ecology.
“This study provides good evidence that we can take any group of species and predict how individual species will respond to changes in the environment through events such as climate change or habitat loss,” says lead author Associate Professor Corey Bradshaw, from the University of Adelaide’s School of Earth and Environmental Sciences.
The researchers analysed life-history and ecological traits in more than 8900 species of the legume, or the Fabaceae plant family, and found a correlation between evolved species’ traits and a particular susceptibility to a species becoming threatened or invasive.
“The urgency and scale of the global biodiversity crisis means we need good generalised predictors of a species’ likelihood of going extinct or becoming invasive in non-native areas,” says Associate Professor Bradshaw.
“Previous studies have been limited by studying one or other of these ‘fates’ in isolation.
“Developing evidence-based rules of thumb for categorising poorly studied species according to their susceptibility will aid decision makers in choosing best ways to allocate finite conservation resources.”
Lists of ‘species to watch’ - both threatened and potentially invasive - should be expanded based on ranking of ‘susceptibility traits’, Associate Professor Bradshaw says. Associate Professor Bradshaw is also employed by the South Australian Research and Development Institute as a senior scientist.
“Our results are particularly valuable where there is sustained habitat loss or fragmentation, especially given the predictions that climate change will simultaneously promote the expansion of invasive alien species and greater extinction rates in others,” he says.

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
