TextPublication details: Grand Forks, ND : University of North Dakota, 1977.Description: 81 leaves : ill. ; 29 cmOnline resources: Abstract: Macro-invertebrate residents of several contiguous Minnesota marshes were monitored from May to Novermber, 1975. The one hundred and twenty-four taxa observed included: Annelida, Crustacea, Hydracarina,Extecta (Odonata, Ephemeroptera, Trichoptera, Hemiptera, Lepidoptera,Coleoptera, and Diptera) and Mollusca. Their occurence over the seasons reflected changing marsh conditions. Most were temporary inhabitants of emergent vegetation before July 30, but many also lived in deep water (or marsh) plant beds that matured later. Class IV: shallow-marsh (Typha sp.) contained more taxa than any other vegetation zone. The survival of invertebrates in the marsh was aided by: selection of suitable habitat,active life spans of short duration, resistant resting stages, time of occurrence synchronized with favorable marsh conditions, and ability to move from unfavorable conditions.
