Leptodiaptomus ashlandi is a zooplankton species widely distributed across Canada and the northern half of the United States in large deep lakes. It occurs in all the Great Lakes.[1]
Adult females of L. ashlandi can be distinguished by their two-segmented urosome and asymmetrical, rounded metasomal wings. Males are characterized by a large lateral spine on leg 5, located in the proximal third of the terminal segment, and by the presence of a slender process on the third segment from the distal end of the right antennule.[2] This species is morphologically similar to other leptodiaptomids (Leptodiaptomus minutus, L. sicilis) and skistodiaptomids (Skistodiaptomus oregonensis).
Ecologyedit
Leptodiaptomus ashlandi are known prey items for a number of native and non-native Great Lakes fishes. They are also prey items for other invertebrate zooplankton. Remains have been found within gut-contents of Mysis diluviana[3] and are trophically below Limnocalanus macrurus.[4]
