Jean V Adams
I provide statistical support to research scientists at the US Geological Survey Great Lakes Science Center and to the bi-national Great Lakes Fishery Commission. This support extends to the sea lamprey control agents of the US Fish and Wildlife Service and Fisheries and Oceans Canada.
I am particularly interested in data visualization to aid in understanding complex systems.

It's like night and day: Diel net-effects on Cercopagidae densities in the Laurentian Great Lakes
In the Laurentian Great Lakes, zooplankters are often sampled using standard ≤ 153 μm mesh nets without regard to the time of day they are collected. We sampled Cercopagidae during 2013–2014 in northern Lake Huron during day, dusk, and night using two different nets (a 0.5 m wide 153 μm mesh “standard” net and a 0.75 m wide 285 μm mesh “Bythotrephes” net) to determine if there were any...Armenio, Patricia M.; Bunnell, David; Adams, Jean V.; Watson, Nicole M.; Woelmer, Whitney
Testing for synchrony in recruitment among four Lake Michigan fish species
In the Great Lakes region, multiple fish species display intra-specific spatial synchrony in 28 recruitment success, with inter-annual climate variation hypothesized as the most likely driver. 29 In Lake Michigan, we evaluated whether climatic or other physical variables could also induce 30 spatial synchrony across multiple species, including bloater (Coregonus hoyi), rainbow smelt 31 (Osmerus...Bunnell, David; Höök, Tomas O.; Troy, Cary D.; Liu, Wentao; Madenjian, Charles P.; Adams, Jean V.
An automated approach to Litchfield and Wilcoxon's evaluation of dose–effect experiments using the R package LW1949
The authors developed a package, LW1949, for use with the statistical software R to automatically carry out the manual steps of Litchfield and Wilcoxon's method of evaluating dose–effect experiments. The LW1949 package consistently finds the best fitting dose–effect relation by minimizing the chi-squared statistic of the observed and expected number of affected individuals and substantially...Adams, Jean V.; Slaght, Karen; Boogaard, Michael A.
Tradeoff between assessment and control of aquatic invasive species: A case study of sea lamprey management in the St. Marys River
Allocating resources between the gathering of information to guide management actions and implementing those actions presents an inherent tradeoff. This tradeoff is evident for control of the Sea Lamprey Petromyzon marinus in the St. Marys River, connecting Lakes Huron and Superior and a major source of parasitic Sea Lampreys to Lake Huron and northern Lake Michigan. Larval Sea Lampreys in the St...Robinson, Jason M.; Wilberg, Michael J.; Adams, Jean V.; Jones, Michael L.
Moss and vascular plant indices in Ohio wetlands have similar environmental predictors
Mosses and vascular plants have been shown to be reliable indicators of wetland habitat delineation and environmental quality. Knowledge of the best ecological predictors of the quality of wetland moss and vascular plant communities may determine if similar management practices would simultaneously enhance both populations. We used Akaike's Information Criterion to identify models predicting a...Stapanian, Martin A.; Schumacher, William; Gara, Brian; Adams, Jean V.; Viau, Nick
Factors associated with the deposition of Cladophora on Lake Michigan beaches in 2012
Deposition of the macroalgae Cladophora spp. was monitored on 18 beaches around Lake Michigan during 2012 at a high temporal frequency. We observed a high degree of spatial variability in Cladophora deposition among beaches on Lake Michigan, even within local regions, with no clear regional pattern in the intensity of Cladophora deposition. A strong seasonal pattern in Cladophora deposition was...Riley, Stephen C.; Tucker, Taaja R.; Adams, Jean V.; Fogarty, Lisa R.; Lafrancois, Brenda Moraska
Evaluating the importance of abiotic and biotic drivers on Bythotrephes biomass in Lakes Superior and Michigan
The ability of planktivorous fishes to exert top-down control on Bythotrephes potentially has far-reaching impacts on aquatic food-webs, given previously described effects of Bythotrephes on zooplankton communities. We estimated consumption of Bythotrephes by planktivorous and benthivorous fishes, using bioenergetics and daily ration models at nearshore (18 m), intermediate (46 m), and offshore (...Keeler, Kevin M.; Bunnell, David B.; Diana, James S.; Adams, Jean V.; Mychek-Londer, Justin G.; Warner, David M.; Yule, Daniel; Vinson, Mark
Sea lamprey mark type, marking rate, and parasite-host relationships for lake trout and other species in Lake Ontario
We examined how attack frequency by sea lampreys on fishes in Lake Ontario varied in response to sea lamprey abundance and preferred host abundance (lake trout > 433 mm). For this analysis we used two gill net assessment surveys, one angler creel survey, three salmonid spawning run datasets, one adult sea lamprey assessment, and a bottom trawl assessment of dead lake trout.Lantry, Brian F.; Adams, Jean V.; Christie, Gavin; Schaner, Teodore; Bowlby, James; Keir, Michael; Lantry, Jana; Sullivan, Paul; Bishop, Daniel; Treska, Ted; Morrison, Bruce
Site-scale disturbance and habitat development best predict an index of amphibian biotic integrity in Ohio shrub and forested wetlands
We determined the best predictors of an index of amphibian biotic integrity calculated from 54 shrub and forested wetlands in Ohio, USA using a two-step sequential holdout validation procedure. We considered 13 variables as predictors: four metrics of wetland condition from the Ohio Rapid Assessment Method (ORAM), a wetland vegetation index of biotic integrity, and eight metrics from a landscape...Micacchion, Mick; Stapanian, Martin A.; Adams, Jean V.
Comparing methods for estimating larval sea lamprey (Petromyzon marinus) density in the St. Marys River for the purposes of control
The St. Marys River is a major producer of parasitic sea lampreys (Petromyzon marinus) to Lake Huron making it an important area for larval control. Bayluscide treatments are conducted in areas of high larval density requiring density estimation at fine spatial scales to inform treatment decisions.Robinson, Jason M.; Wilberg, Michael J.; Adams, Jean V.; Jones, Michael L.

Having completed the build, the R/V Arcticus is launched and is now ready for its sea trials.

With all but one deck in place, it's beginning to look like a ship. In this video, the pilot house is installed.
The hull of the vessel is complete. Burger Boat Co. removes the hull from the construction bay and uses cranes to flip it over. Then, it's taken back to the bay to continue working.
Part 2 of our series on the R/V Arcticus construction covers the frame and fuel tank completion.
