Cellular hallmarks of thermal limits are evolutionarily conserved in nematodes, and changes in surface to volume ratio reflect restricted aerobic metabolism at these limits.
A novel species-sorting experiment finds that phylogenetically and functionally distinct microbial communities emerge under different temperature conditions due to the resuscitation of latent diversity.
Microbiome and transcriptomic profiling of genetically selected tropical fish with high and low tolerance to cold exposure revealed host control over microbiome composition and response to temperature changes.
A thermal stability-based proteomic analysis identifies cytoplasmic PEBP1 as a mediator of mitochondrial dysfunction-induced stress response, highlighting its potential role in cellular adaptation mechanisms.
Natural temperature variation across an optimal reproductive range for wild flies (Drosophila melanogaster) modulates the impact of sexual conflict on female fitness via asymmetric effects on pre- and post-copulatory male harm mechanisms.

Seasonal selection is a general feature of Drosophila melanogaster genetic variation, occurring in North American and European populations and affecting large proportions of the genome.
When an essential metabolic gene in E. coli is mutationally inactivated, subsequent evolution rarely reverts the mutation to wild type but rather follows unexpected paths that rewire metabolic fluxes.
