This side offers an interactive key which is meant to aid the identification of the non-insect aquatic macroinvertebrates found in the rivers and streams of North Dakota. It is primarily meant to be used by students, citizen groups, and professionals and be useful to implementing a biomonitoring program. This key is not a traditional dichotomous key. It includes many different groups such as snails, daphnia, crayfish, leeches, and oligochaetes. For some of the groups it goes all the way down to species level. Other groups may only go down to the Order, Family or Phylum level (the sponges and flatworms).The key has been based on 7 years of collections carried out by the North Dakota Department of Health and 5 years of collecting carried out by Dr. Andre DeLorme's macroinvertebrate lab at Valley City State University. A list with short biographies of the participating scientists completes the side. ... [Information of the supplier, modified]
