Your study is too important to be their learning experience!
This Nectopsyche from the Sabine River in Texas, USA, is an active swimmer. The case, assembled from silk and willow roots, is neutrally buoyant with a longer keel running along the dorsal surface to allow the wildly spinning legs to pull the critter through the water column in a straight line! Lovely! Our Laboratory identifies […]
Read Aquatic Insects / Benthic Macroinvertebrates: Nectopsyche
Although aquatic insects, plants and fishes produce a tons of biomass every year, most ecologists tend to think of the fate of this biomass only within the confines of production within the aquatic habitats they study.
The week prior to memorial day we presented our poster on the limitations of bioassessment study designs to assess change at a local scale—with emphasis on the detrimental effects of fixed-count sub-sampling on fisheries resources studies. The 2014 NABS / SFS meeting was held in Portland OR, in conjunction with SWS, ASLO, and the Phycological […]
I recently presented a research paper on three common errors associated with using bioassessment methods for non-bioassessment purposes at the Annual Meeting of the Western Division American Fisheries Society. The presentation focused on errors relating to development and design of macroinvertebrate bioassessment models, as well as some issues on the myths of variance homogeneity and […]
Well, you may have noticed that I have not said anything about the Yellowstone River Oil Spill since our original entry. Yet, in truth, we have been busily working on the project in-house. The experience has not been all-together positive; quite the contrary. This entry deals with how the public loses because of bureaucracy; bureaucracy […]
The Exxon-Mobil oil spill on the Yellowstone River made national and international news this weekend; indeed, my first awareness of it came from the BBC news website. As a macroinvertebrate ecologist, I cannot help but reflect how the aquatic insects might be affected. It might seem silly to worry about “bugs” when images of beautiful […]
When monitoring environmental impacts of anthropogenic activities, it is useful to collect ancillary data to use as covariates. These variables can help account for natural variation in the communities studies, which helps prevent their confounding of observations. In our work with benthic macroinvertebrate assemblages, we always collect flow measures for this purpose (near-substrate flow measures […]
So I started with one of my favorite little beetles, the Haliplids, but really, honestly… the aquatic insect with which the general public is most fascinated is probably the Odonata (dragonflies and damselflies). This seems to exclude fly-fisher-persons from the category of general public (because of their obsession with mayflies, caddisflies, and stoneflies). But, lets […]
If you are interested in attaining a copy of the document, post a comment here so I can gauge community interest in these wonderful aquatic insect pictures.
The Jefferson River Flooded last weekend. All the hay fields in the area were flooded and roads that have not been submerged in recent history became gentle rivulets. The High water is good for the Jefferson River because it has had many years of below average flows–and fine sediments have built up among the interstitial […]
