We may be in the middle of an insect mass extinction. The once abundant Rocky Mountain locust was last seen in 1902. Under the Mikheyev Group, Peiyu Yuan used data from a related extant locust species and comparative genomics to identify artifacts in museum data of the Rocky Mountain locust.
Researchers from the Australian National University (ANU) have discovered several new species of butterflies and moths in Northern Australia, identifying a conservation stronghold of national and international significance.
The amazing diversity we see in Australian animal developed early and has slowed considerably in the last 10 million years, say Ian Brennan and Scott Keogh from the ANU Research School of Biology.
Ecological stressors such as predation can shape ecosystems, driving prey population and community dynamics through indirect, non-consumptive effects that may cascade across generations through parental effects.
While we know many things about E. coli under laboratory conditions, relatively little is known about the ecology of this bacterium in the environment.
Each cell division comes with the risk of mutations that could eventually lead to cancer. How do organisms attain their mature sizes without succumbing to cancer? What happens when large-bodied lineages shrink in size? Can cancer risk constrain body size evolution?
