Henry Thompson is a Biological Science Technician based in Millersburg, MI.
I am a biological technician with Hammond Bay Biological Station, hired in April of 2011. I graduated with a B.S. in Math and Computer Science in May of 2003. My biological experiences start from 2000 to 2003 when I started working in summers to work on brook trout habitat restoration and streambank erosion prevention for the Cheboygan Conservation District. From 2005 to 2011, I worked part time for Michigan State University as a technician for carrying out various lamprey projects.

Fine-scale acoustic telemetry reveals unexpected lake trout, Salvelinus namaycush, spawning habitats in northern Lake Huron, North America
Previous studies of lake trout, Salvelinus namaycush, spawning habitat in the Laurentian Great Lakes have used time- and labour-intensive survey methods and have focused on areas with historic observations of spawning aggregations and on habitats prejudged by researchers to be suitable for spawning. As an alternative, we used fine-scale acoustic telemetry to locate, describe and compare lake troutAuthorsThomas Binder, Steve A. Farha, Henry T. Thompson, Christopher Holbrook, Roger A. Bergstedt, Stephen Riley, Charles R. Bronte, Ji He, Charles C. KruegerA portable trap with electric lead catches up to 75% of an invasive fish species
A novel system combining a trap and pulsed direct current electricity was able to catch up to 75% of tagged invasive sea lamprey Petromyzon marinus in free-flowing streams. Non-target mortality was rare and impacts to non-target migration were minimal; likely because pulsed direct current only needed to be activated at night (7 hours of each day). The system was completely portable and the annualAuthorsNicholas S. Johnson, Scott M. Miehls, Lisa M. O'Connor, Gale Bravener, Jessica Barber, Henry T. Thompson, John A. Tix, Tyler BruningUse of oviduct-inserted acoustic transmitters and positional telemetry to estimate timing and location of spawning: a feasibility study in lake trout, Salvelinus namaycush
Background Oviduct-inserted transmitters have shown promise for determining precise location of spawning in fishes. Use of traditional manual tracking to locate expelled oviduct transmitters is laborious and accurate estimates of time of transmitter expulsion require frequent surveys. We tested the feasibility of using oviduct-inserted transmitters with positional telemetry to estimate time and loAuthorsThomas R. Binder, Christopher M. Holbrook, Scott M. Miehls, Henry T. Thompson, Charles C. KruegerLake trout in northern Lake Huron spawn on submerged drumlins
Recent observations of spawning lake trout Salvelinus namaycush near Drummond Island in northern Lake Huron indicate that lake trout use drumlins, landforms created in subglacial environments by the action of ice sheets, as a primary spawning habitat. From these observations, we generated a hypothesis that may in part explain locations chosen by lake trout for spawning. Most salmonines spawn in stAuthorsStephen C. Riley, Thomas Binder, Nigel J.

KruegerNew insight into the spawning behavior of lake trout, Salvelinus namaycush, from a recovering population in the Laurentian Great Lakes
Spawning behavior of lake trout, Salvelinus namaycush, is poorly understood, relative to stream-dwelling salmonines. Underwater video records of spawning in a recovering population from the Drummond Island Refuge (Lake Huron) represent the first reported direct observations of lake trout spawning in the Laurentian Great Lakes. These observations provide new insight into lake trout spawning behavioAuthorsThomas R. Binder, Henry T. Thompson, Andrew M. Muir, Stephen C. Riley, J. Ellen Marsden, Charles R. Bronte, Charles C. KruegerBlocking and guiding adult sea lamprey with pulsed direct current from vertical electrodes
Controlling the invasion front of aquatic nuisance species is of high importance to resource managers. We tested the hypothesis that adult sea lamprey (Petromyzon marinus), a destructive invasive species in the Laurentian Great Lakes, would exhibit behavioral avoidance to dual-frequency pulsed direct current generated by vertical electrodes and that the electric field would not injure or kill seaAuthorsNicholas S. Johnson, Henry T. Thompson, Christopher M. Holbrook, John A. TixSea lamprey orient toward a source of a synthesized pheromone using odor-conditioned rheotaxis
Characterization of vertebrate chemo-orientation strategies over long distances is difficult because it is often not feasible to conduct highly controlled hypothesis-based experiments in natural environments. To overcome the challenge, we couple in-stream behavioral observations of female sea lampreys (Petromyzon marinus) orienting to plumes of a synthesized mating pheromone, 7a,12a,24-trihydroxy-AuthorsNicholas S.
