Partial migration and spawning movements of humpback chub in the Little Colorado River are better understood using data from autonomous PIT tag antennas
Autor: Maria C. Dzul, David R. Van Haverbeke, William L. Kendall, Charles B. Yackulic, Dana L. Winkelman, Michael D. Yard
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 78:1057-1072
Choosing whether or not to migrate is an important life history decision for many fishes. Here we combine data from physical captures and detections on autonomous passive integrated transponder (PIT) tag antennas to study migration in an endangered f

As the prey thickens: rainbow trout select prey based upon width not length
Autor: Michael J. Dodrill, Josh Korman, Theodore A. Kennedy, Charles B. Yackulic, Michael D. Yard
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 78:809-819
Drift-feeding fish are typically considered size-selective predators. Yet, few studies have explicitly tested which aspect of prey “size” best explains size selection by drift-foraging fish. Here, we develop a Bayesian discrete choice model to ev

Of travertine and time: otolith chemistry and microstructure detect provenance and demography of endangered humpback chub in Grand Canyon, USA.
Autor: Karin E Limburg, Todd A Hayden, William E Pine, Michael D Yard, Reinhard Kozdon, John W Valley
Publikováno v: PLoS ONE, Vol 8, Iss 12, p e84235 (2013)
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

Inferring species interactions through joint mark-recapture analysis
Autor: Josh Korman, Michael D. Yard, Charles B. Yackulic, Maria C. Dzul
Publikováno v: Ecology. 99:812-821
Introduced species are frequently implicated in declines of native species. In many cases, however, evidence linking introduced species to native declines is weak. Failure to make strong inferences regarding the role of introduced species can hamper

Does Bioelectrical Impedance Analysis Accurately Estimate the Physiological Condition of Threatened and Endangered Desert Fish Species?
Autor: Kimberly L. Dibble, Charles B. Yackulic, David L. Ward, Michael D. Yard
Publikováno v: Transactions of the American Fisheries Society. 146:888-902
Bioelectrical impedance analysis (BIA) is a nonlethal tool with which to estimate the physiological condition of animals that has potential value in research on endangered species. However, the effectiveness of BIA varies by species, the methodology

Effects of environmental covariates and density on the catchability of fish populations and interpretation of catch per unit effort trends
Autor: Michael D. Yard, Josh Korman
Publikováno v: Fisheries Research. 189:18-34
Quantifying temporal and spatial trends in abundance or relative abundance is required to evaluate effects of harvest and changes in habitat for exploited and endangered fish populations. In many cases, the proportion of the population or stock that
