Genomics Climate change is likely to cause new and extreme environmental conditions, and we have little understanding of how species will cope. Caddisfly larvae live wrapped in protective cases of grit or fibers among the stones of fast-flowing freshwater streams. Ebner et al. examined the proteome of the northern European caddisfly Crunoecia irrorata when raised at different temperatures between 10° and 20°C. This species normally lives in the steady environment of groundwater springs, but this study shows that it appears to have compensatory mechanisms that respond to warming. The authors found that differential expression of proteins with functional annotation in candidate thermoregulatory systems increased as temperature increased. It seems that C. irrorata has a higher tolerance to temperature variation than previously thought. Molec. Ecol. 10.1111/mec.15225 (2019).
