Environmental Genomics And Transcriptomics Of Salpa thompsoni And Population Genetic Variation Of Euphausia superba In The Southern Ocean
The Western Antarctic Peninsula (WAP) region, which is experiencing increased sea surface temperatures, is a highly productive region of the Southern Ocean, supporting dense populations of the salp Salpa thompsoni and krill Euphuasia superba. Ecological data suggest that important species like salps...
