New Baetidae (Insecta: Ephemeroptera) Records from.
The classification of species into genera also has changed markedly in the last 40 years. The family Baetidae has seen the greatest number of changes, with multiple new genera described, several more recent generic revisions, and some species going back and forth between genera several times.
This key covers larvae of the 11 Genera of Baetidae that we have collected in North Dakota rivers and streams. Baetidae are rather fragile larvae, so they may appear rather beaten up in your samples. Examples in some of these photos are missing the gills, antennae, or legs that easily break off during sampling procedures.
In the present study, assessment, and comparison of the aquatic macroinvertebrates and their abiotic preferences were done in three river basins.
We assessed and compared abiotic preferences of aquatic macroinvertebrates in three river basins located in Ecuador, Ethiopia and Vietnam. Upon using logistic regression models we analyzed the relationship between the probability of occurrence of five macroinvertebrate families, ranging from pollution tolerant to pollution sensitive, (Chironomidae, Baetidae, Hydroptilidae, Libellulidae and.
A memorable essay describing subsistence gill-net fishing on the Kobuk River, just south of the Noatak River, can be found in Jans (1993). Other families of fishes are apparently represented by one species each: northern pike, burbot (a freshwater member of the cods), Alaska blackfish (a Beringian relict), longnose sucker, slimy sculpin, and ninespine stickleback.
Scientific rigor is critical to building trust in the stewardship measures we recommend. Peer-reviewed publication of our freshwater research, environmental education, and watershed restoration activities is a fundamental communication tool.
