Pteronarcys californica Genome sequencing and assembly. Pteronarcys californica

Pteronarcys californica is a member of the stonefly family Pteronarcyidae and is commonly referred to as the giant salmonfly by anglers. P. californica is the largest species of stonefly in the western United States and is of ecological, cultural, and economical importance. Giant salmonfly populations have experienced a substantial decline in the past few decades as they have become regionally extinct in numerous rivers in Utah, Colorado, and Montana. They are incredibly sensitive to pollution, warming temperatures, flow modification, land-use change, sedimentation, and other environmental stressors on energy flows. Ecological variables pertaining to the subsistence of giant salmonfly populations have been well-recorded, but the genomic features of this species (or family) had not been explored before this.
