Fifteen species incubated eggs during the polar night and released their offspring in early April. Three species incubated eggs from late spring till late summer. The appearance of the youngest juveniles, indicating the hatching period, is presented for 63 species. Most of the species studied were K strategists, with large eggs of over 1 mm diameter; only one species (Hyperoche medusarum ) was r – strategist.}, type={Article}, title={Life cycles of some Arctic amphipods}, URL={http://rhis.czasopisma.pan.pl/Content/110709/PDF-MASTER/ppr23-253.pdf}, keywords={Arctic amphipods, breeding, life cycles, eggs incubation}, }
