Editorial: The threat of invasive alien species and the challenge of climate change
## Editorial: The Threat of Invasive Alien Species and the Challenge of Climate Change The escalating impacts of climate change are not occurring in isolation; they are synergistically amplifying the threat posed by invasive alien species. Altered ocean temperatures, shifting currents, and increased storm frequency create unprecedented opportunities for non-native organisms to establish and proliferate, disrupting fragile marine ecosystems. Addressing this complex interplay demands integrated data and rigorous analysis.
Koalas nearly went extinct before humans arrived, DNA study reveals
A groundbreaking DNA study has significantly revised our understanding of koala evolutionary history. Analysis of hundreds of genomes, calibrated using a newly calculated mutation rate, reveals a dramatic population bottleneck approximately 100,000 years ago—predating human arrival in Australia. Researchers determined that all extant koalas descend from a small, resilient group that endured severe climate fluctuations before repopulating eastern Australia. This discovery underscores the species’ inherent vulnerability and highlights the importance of ongoing conservation efforts, as explored further in our article, "Meet the Solenostomus snuffleupagus."
