Ecology

M. affinis bụ otu n'ime glacial Baltic. Na mbụ ụdị mmiri dị ọcha, ọ dịkwa na ọdọ mmiri. M. affinis na-ebi n'ala ala dị nro, mgbe ụfọdụ ọbụna dị ka 10,000-20,000 mana ọ na-abụkarị narị puku mmadụ na puku kwuru puku mmadụ kwa square mita. ^[2] Amphipod nwere ọrụ dị mkpa na bioturbation (ịgwakọta na oxidating sedimenti ala). Monoporeia na-eri nri na phytoplankton na ihe ndị mebiri emebi na-emikpu na ala. M. affinis bụ anụ anụ n'onwe ya nke Saduria entomon, Harmothoe sarsi (a polychaete ) na azụ ndị dị ka cod, azụ asa na sculpin mpi anọ, Myoxocephalus quadricornis .
