Size spectra analysis of a decade of Laurentian Great Lakes data
Autor: Zachary S. Feiner, Euan D. Reavie, Alexander Y. Karatayev, James M. Watkins, W. Gary Sprules, Lyubov E. Burlakova, Lars G. Rudstam, Doran M. Mason, Thomas M. Evans, Anne E. Scofield
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 79:183-194
Size spectra analysis (SSA) is used to detect changes in food webs by simplifying complex community structures through abundance-versus-biomass considerations. We applied SSA to 10 years (2006–2015) of data on Great Lakes organisms ranging in size

A comprehensive evaluation of Daphnia pulex foraging energetics and the influence of spatially heterogeneous food
Autor: Audrey Helen Reid, W. Gary Sprules
Publikováno v: Inland Waters. 8:50-59
Aquatic organisms are distributed in a heterogeneous, nonrandom manner, and zooplankton are known to seek out and orient themselves within regions of high food concentration. Yet, the energetics as...

Limitations of fluoridation effectiveness studies: Lessons from Alberta, Canada
Autor: Bill Osmunson, Hardy Limeback, James S. Beck, Michael Connett, Donald R. Davis, Christopher Neurath, W. Gary Sprules
Publikováno v: Community Dentistry and Oral Epidemiology. 45:496-502
A paper published in this journal, “Measuring the short-term impact of fluoridation cessation on dental caries in Grade 2 children using tooth surface indices,” by McLaren et al had shortcomings in study design and interpretation of results, and

Internal waves and mixing in the epilimnion of a lake affects spatial patterns of zooplankton in a body-size dependent manner
Autor: Patricia Pernica, W. Gary Sprules, Mathew G. Wells
Publikováno v: Limnology and Oceanography: Fluids and Environments. 3:279-294
Zooplankton are not uniformly distributed in space but are patchy at multiple scales as a result of interactions between their directed motion and both large- and small-scale water currents. Using field data from July and August 2009 and 2010 we repo

The utility of body size indices derived from optical plankton counter data for the characterization of marine zooplankton assemblages
Autor: W. Gary Sprules, Alex W. Herman, Karla L. Krupica
Publikováno v: Continental Shelf Research. 36:29-40
To evaluate the utility of size-based indices derived from an Optical Plankton Counter (OPC) through detection of spatial and temporal trends in zooplankton biomass, zooplankton size data were collected with an OPC across the Scotian Shelf region of

Energy acquisition and allocation patterns of lake whitefish (Coregonus clupeaformis) are modified when dreissenids are present
Autor: Timothy B. Johnson, W. Gary Sprules, Michael D. Rennie
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 69:41-59
We evaluated the effects of dreissenid-induced food web changes on rates of lake whitefish (Coregonus clupea- formis) energy acquisition and allocation in North American populations. We used mass-balance models of lake whitefish growth and methylmerc

Effects of Bythotrephes longimanus (Crustacea, Cladocera) on the abundance, morphology, and prey community of Leptodora kindtii (Crustacea, Cladocera)
Autor: W. Gary Sprules, Sophie E. Foster, Angela L. Strecker
Publikováno v: Hydrobiologia. 683:163-172
We hypothesized that native Leptodora kindtii would be shorter and have smaller feeding baskets in central Ontario lakes with greater abundances of small-bodied zooplankton prey, and that differences in zooplankton size among lakes could be attribute

Carbon-based balanced trophic structure and flows in the offshore Lake Ontario food web before (1987–1991) and after (2001–2005) invasion-induced ecosystem change
Autor: W. Gary Sprules, Thomas J. Stewart
Publikováno v: Ecological Modelling. 222:692-708
Replicate mass-balanced solutions to Ecopath models describing carbon-based trophic structures and flows were developed for the Lake Ontario offshore food web before and after invasion-induced disruption. The food webs link two pathways of energy and
