Haplotype-resolved chromosome-level genome assemblies of four <i>Diamesa</i> species reveal the genetic basis of cold tolerance and high-altitude adaptations in arctic chironomids
Our findings support the hypothesis that genome size condensation and selective gene family changes underpin survival in cold environments. These new genome assemblies provide a valuable resource for studying adaptation, speciation, and conservation in cold-specialist insects. Future integration of gene expression and population genomics will further clarify the evolutionary resilience of Diamesa in a warming world.
