Evolutionary changes in the genetic code of yeasts

Yeasts are some of the most important microbes used in biotechnology. Saccharomyces cerevisiae, the type of yeast used for making bread and beer, is just one representative of more than 1,500 yeast species found around the ...

On the expansion threshold of a species' range

What stops a species adapting to an ever-wider range of conditions, continuously expanding its geographic range? The biomathematician Jitka Polechová, an Elise Richter Fellow at the University of Vienna, has published a ...

'Island' grevillea drifts through time

Genetic testing of the bird-pollinated Grevillea georgeana (Proteaceae) on 'terrestrial islands' in WA has found most are so isolated that their evolution has become driven by genetic drift.

Lack of diversity a weak link for dolphins

Limited gene flow between groups of Australian snubfin and Indo-Pacific humpback dolphins in WA's north may make them more vulnerable to the environmental impacts of coastal industrial developments.

Common genetic ancestors lived during roughly same time period

Mitochondrial Eve and Y-chromosomal Adam—two individuals who passed down a portion of their genomes to the vast expanse of humanity—are known as our most recent common ancestors, or MRCAs. But many aspects of their existence, ...
