A koala perched in a tree, looking slightly downward, with a soft green blurred background. A black banner in the upper left reads, “What this enabled.” A larger black text box across the lower part of the image reads: “Using whole-genome data from 418 koalas across 27 populations, researchers showed that resilience cannot be judged by diversity alone. Bottlenecked Victorian populations showed signs of recovery, including rising effective population size, the reappearance of rare variants, and lower mutational load than northern populations.”

A koala clinging to a tree trunk and looking toward the camera, with a softly blurred forest background. A black text box across the lower part of the image reads: “This study shows why genome-scale data matter for conservation: demographic history, rare alleles, recombination, mutation, and population growth can all shape resilience in ways simple diversity measures may miss.” The words “genome-scale” are highlighted in yellow.

🐨🧬What makes a population resilient?
This koala study shows the answer is more complex than diversity alone. Genome-scale data can reveal recovery, rare variants, and demographic change that simpler measures may miss.🐨🧬
