Probability of acoustic transmitter detections by receiver lines in Lake Huron: results of multi-year field tests and simulations Probability of acoustic transmitter detections by receiver lines in Lake Huron: results of multi-year field tests and simulations
Background Advances in acoustic telemetry technology have led to an improved understanding of the spatial ecology of many freshwater and marine fish species. Understanding the performance of acoustic receivers is necessary to distinguish between tagged fish that may have been present but not detected and from those fish that were absent from the area. In this study, two stationary...

Spatial and temporal variation in positioning probability of acoustic telemetry arrays: Fine-scale variability and complex interactions Spatial and temporal variation in positioning probability of acoustic telemetry arrays: Fine-scale variability and complex interactions
Background As popularity of positional acoustic telemetry systems increases, so does the need to better understand how they perform in real-world applications, where variation in performance can bias study conclusions. Studies assessing variability in positional telemetry system performance have focused primarily on position accuracy, or comparing performance inside and outside the array...

Do intracoelomic telemetry transmitters alter the post-release behaviour of migratory fish? Do intracoelomic telemetry transmitters alter the post-release behaviour of migratory fish?
Electronic tags have become a common tool in fish research, enhancing our understanding of how fish interact with their environment and move among different habitats, for estimating mortality and recording internal physiological states. An often-untested assumption of electronic tagging studies is that tagged fish are representative of untagged conspecifics and thus show ‘normal’...

Seasonal thermal ecology of adult walleye (Sander vitreus) in Lake Huron and Lake Erie Seasonal thermal ecology of adult walleye (Sander vitreus) in Lake Huron and Lake Erie
The purpose of this study was to characterize thermal patterns and generate occupancy models for adult walleye from lakes Erie and Huron with internally implanted biologgers coupled with a telemetry study to assess the effects of sex, fish size, diel periods, and lake. Sex, size, and diel periods had no effect on thermal occupancy of adult walleye in either lake. Thermal occupancy...

Acoustic telemetry reveals large-scale migration patterns of walleye in Lake Huron Acoustic telemetry reveals large-scale migration patterns of walleye in Lake Huron
Fish migration in large freshwater lacustrine systems such as the Laurentian Great Lakes is not well understood. The walleye (Sander vitreus) is an economically and ecologically important native fish species throughout the Great Lakes. In Lake Huron walleye has recently undergone a population expansion as a result of recovery of the primary stock, stemming from changing food web dynamics...

Of travertine and time: otolith chemistry and microstructure detect provenance and demography of endangered humpback chub in Grand Canyon, USA Of travertine and time: otolith chemistry and microstructure detect provenance and demography of endangered humpback chub in Grand Canyon, USA
We developed a geochemical atlas of the Colorado River in Grand Canyon and in its tributary, the Little Colorado River, and used it to identify provenance and habitat use by Federally Endangered humpback chub, Gila cypha. Carbon stable isotope ratios (δ13C) discriminate best between the two rivers, but fine scale analysis in otoliths requires rare, expensive instrumentation. We therefore
