Daniel L Yule
Biography
Dan was born and raised in western Wisconsin and attended New Richmond Senior High School. He obtained his BS degree from the University of Wisconsin – River Falls (1989) and his MS from Utah State University (1992). After completing his studies he worked for 9 years as a Fish Biologist with the Reservoir Research Crew of the Wyoming Game and Fish Department. From 2001-2003 he worked as a Fish Research Scientist with the Minnesota Department of Natural Resources. Since 2004, Dan has held his current position as a Fishery Research Scientist with the Great Lakes Science Center – Lake Superior Biological Station. In his free time Dan enjoys hiking, camping, fishing, following WI sports teams, and watching movies. Dan is a huge fan of historical fiction novels.

Evaluating the sustainability of a Cisco fishery in Thunder Bay, Ontario, under alternative harvest policies
Sustainable management of fish stocks is promoted through the application of management strategy evaluations (MSEs), providing information to managers on the relative performance of alternative management approaches (strategies) while accounting for uncertainty. In this study, we developed a simplified MSE of a stock of Cisco Coregonus artedi...
Fisch, Nicholas C; Bence, James R.; Myers, Jared T.; Berglund, Eric K.; Yule, Daniel A comparison of age- and size-structured assessment models applied to a stock of cisco in Thunder Bay, Ontario
Stock assessments are critical to modern fisheries management, supporting the calculation of key reference variables used to make informed management decisions. However, there is still considerable uncertainty as to which class of assessment models is appropriate to use under different circumstances. A common class of models used when age data are...
Fisch, Nicholas C; Bence, James R.; Myers, Jared T.; Berglund, Eric K.; Yule, Daniel Status and trends in the Lake Superior fish community, 2016
In 2016, the Lake Superior fish community was sampled with daytime bottom trawls at 76 nearshore and 35 offshore stations. Spring and summer water temperatures in 2016 were warmer than average and considerably warmer than observed in 2014 and 2015. In the nearshore zone, a total of 17,449 individuals from 20 species or morphotypes were collected....
Vinson, Mark; Evrard, Lori M.; Gorman, Owen T.; Yule, Daniel Ciscoes (Coregonus, subgenus Leucichthys) of the Laurentian Great Lakes and Lake Nipigon
This study of the ciscoes (Coregonus, subgenus Leucichthys) of the Great Lakes and Lake Nipigon represents a furtherance through 2015 of field research initiated by Walter Koelz in 1917 and continued by Stanford Smith in the mid-1900s—a period spanning nearly a century. Like Koelz’s study, this work contains information on taxonomy, geographical...
Eshenroder, Randy L.; Vecsei, Paul; Gorman, Owen T.; Yule, Daniel; Pratt, Thomas C.; Mandrak, Nicholas E.; Bunnell, David B.; Muir, Andrew M. Challenge to the model of lake charr evolution: Shallow- and deep-water morphs exist within a small postglacial lake
All examples of lake charr (Salvelinus namaycush) diversity occur within the largest, deepest lakes of North America (i.e. > 2000 km2). We report here Rush Lake (1.3 km2) as the first example of a small lake with two lake charr morphs (lean and huronicus). Morphology, diet, life history, and genetics were examined to demonstrate...
Chavarie, Louise; Muir, Andrew M.; Zimmerman, Mara S.; Baillie, Shauna M.; Hansen, Michael J.; Nate, Nancy A.; Yule, Daniel L.; Middel, Trevor; Bentzen, Paul; Krueger, Charles C. Seasonal and diel effects on acoustic fish biomass estimates: application to a shallow reservoir with untargeted common carp (Cyprinus carpio)
The aim of the present study was to understand how seasonal fish distributions affect acoustically derived fish biomass estimates in a shallow reservoir in a semi-arid country (Tunisia). To that end, sampling events were performed during four seasons (spring (June), summer (September), autumn (December) and winter (March)) that included day and...
Djemali, Imed; Yule, Daniel; Guillard, Jean Status and trends in the Lake Superior fish community, 2015
In 2015, the Lake Superior fish community was sampled with daytime bottom trawls at 76 nearshore and 33 offshore stations. Spring and summer water temperatures in 2015 were colder than average, but warmer than that observed in 2014. In the nearshore zone, a total of 11,882 individuals from 22 species or morphotypes were collected. Nearshore...
Vinson, Mark; Evrard, Lori M.; Gorman, Owen T.; Yule, Daniel L. 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...
Keeler, Kevin M.; Bunnell, David B.; Diana, James S.; Adams, Jean V.; Mychek-Londer, Justin G.; Warner, David M.; Yule, Daniel; Vinson, Mark Impact of fishing and stocking practices on Coregonid diversity
Fish species diversity can be lost through interacting stressors including habitat loss, stocking and overfishing. Although a multitude of stressors have played a role in the global decline of coregonid (Coregonus spp.) diversity, a number of contemporary studies have identified habitat loss stemming from eutrophication as the primary cause....
Anneville, Orlane; Lasne, Emilien; Guillard, Jean; Eckmann, Reiner; Stockwell, Jason D.; Gillet, Christian; Yule, Daniel Spatial synchrony in cisco recruitment
We examined the spatial scale of recruitment variability for disparate cisco (Coregonus artedi) populations in the Great Lakes (n = 8) and Minnesota inland lakes (n = 4). We found that the scale of synchrony was approximately 400 km when all available data were utilized; much greater than the 50-km scale suggested for...
Myers, Jared T.; Yule, Daniel L.; Jones, Michael L.; Ahrenstorff, Tyler D.; Hrabik, Thomas R.; Claramunt, Randall M.; Ebener, Mark P.; Berglund, Eric K. Status and trends in the Lake Superior fish community, 2014
In 2014, the Lake Superior fish community was sampled with daytime bottom trawls at 73 nearshore and 30 offshore stations. Spring and summer water temperatures were the coldest measured for the period of records for the surveys. In the nearshore zone, a total of 15,372 individuals from 28 species or morphotypes were collected. Nearshore lakewide...
Vinson, Mark; Evrard, Lori M.; Gorman, Owen T.; Yule, Daniel Foraging and predation risk for larval cisco (Coregonus artedi) in Lake Superior: a modelling synthesis of empirical survey data
The relative importance of predation and food availability as contributors to larval cisco (Coregonus artedi) mortality in Lake Superior were investigated using a visual foraging model to evaluate potential predation pressure by rainbow smelt (Osmerus mordax) and a bioenergetic model to evaluate potential starvation risk. The models were informed...
