Aquatic Insects / Benthic Macroinvertebrates: Nectopsyche

Tuesday, January 2nd, 2018

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 […]

Semiaquatic Riparian Aquatic Insects

Friday, April 1st, 2016

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 New Laboratory

Monday, August 10th, 2015

We moved into our new laboratory in March 2015 and it is Great!  We have a conference / meeting room available for classes and public meetings,  our standard laboratory space, and an ecological library /study area where the magic happens! Current Projects include: Sabine River, Texas Yellowstone National Park Baseline Monitoring, Sublette County (WY), Baseline Water […]

Yellowstone River Oil Spill- Redeux

Tuesday, August 23rd, 2011

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 […]

Biological Monitoring Covariates

Thursday, August 5th, 2010

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 […]

Holston River

Thursday, July 22nd, 2010

Time for a sort post; please forgive the mushiness I’m short of technical material. I Just got back from my Holston River Survey with the Academy of Natural Sciences.  It was great to see the Holston River again; the invertebrates are especially diverse and familiar–just like old friends. Speaking of old friends, the rest of […]

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.

Aquatic Insect Identifications

Monday, June 28th, 2010

Identification of macroinvertebrate samples from Sublette County, WY is progressing at faster pace with the addition of Esmeralda to our team.  She is a meticulous sorter and has a sorting efficiency of 97-100%!  This is impressive to me because, some of the other companies I have worked for have the sorters strive for 90%.  The […]

~Holston River Tennessee~

Thursday, June 24th, 2010

The Zone of periodically inundated waters is called the “varial zone” and the community structure can deviate dramatically from the structure of permanently inundated river bottom.

~New Fork River~

Thursday, June 24th, 2010

Changes in the relative abundance of these species might result from changes in the amount of sediment entrained in the river.
