Mercury and molt: no strong Hg trend across songbird primaries

Creator:: Ramsden, Danielle K., Low, Katherine E., Jackson, Allyson K., Emery, Colleen, and Eagles-Smith, Collin A.
Abstract:: Mercury (Hg) is a bioaccumulative metal that can threaten the health of wild birds. Feathers are commonly used biomonitoring tools for non-lethally estimating Hg exposure in birds because they contain stable Hg concentrations upon completion of feather growth, when blood flow to the feather has stopped. Despite the common use...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...

Recovery potential of black rockfish, Sebastes melanops Girard, recompressed following barotrauma

Creator:: Pribyl, A. L., Schreck, C. B., Kent, M. L., Kelley, K. M., and Parker, S. J.
Abstract:: Overfished species of rockfish, Sebastes spp., from the Northeast Pacific experience high bycatch mortality because of ‘barotrauma’, a condition induced from the rapid change in pressure during capture. Field experiments show that it may be possible for rockfish to recover from barotrauma if quickly recompressed; however, no work has followed...

Internal helminth parasites of the lesser prairie-chicken Tympanuchus pallidicinctus in southwestern Kansas: incidence, burden, and effects

Creator:: Robel, Robert J., Walker, Thomas L. Jr, Hagen, Christian A., Ridley, Robert K., Kemp, Kenneth E., and Applegate, Roger D.
Abstract:: We conducted a 3-year study of helminth parasites to assess their effect on the lesser prairie-chicken Tympanuchus pallidicinctus. Helminth parasites were found in most of the examined wild prairie chicken carcasses: 95% had eye worm Oxyspirura petrowi, 92% had stomach worm Tetrameres sp., and 59% had caecal worm Subulura sp....

Cumulative effects of riparian disturbances along high desert trout streams of the John Day Basin, Oregon

Creator:: Li, Hiram W., Lamberti, Gary A., Pearsons, Todd N., Tait, Cynthia K., Li, Judith L., and Buckhouse, John C.
Abstract:: In a study of cumulative effects of riparian disturbance by grazing on the trophic structure of high desert trout streams, watersheds with greater riparian canopy had higher standing crops of rainbow trout Oncorhynchus mykiss, lower daily maximum temperatures (range, 16-23°C compared with 26-31°C), and perennial flow. Watershed aspect influenced the...

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus)

Creator:: Vaux, Felix, Rasmuson, Leif K., Kautzi, Lisa A., Rankin, Polly S., Blume, Matthew T. O., Lawrence, Kelly A., Bohn, Sandra, and O'Malley, Kathleen G.
Abstract:: Little is known about intraspecific variation within the deacon rockfish (Sebastes di‐ aconus), a recently described species found in the northeast Pacific Ocean. We in‐ vestigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area...

Paenibacillus thiaminolyticus is not the cause of thiamine deficiency impeding lake trout (Salvelinus namaycush) recruitment in the Great Lakes

Creator:: Richter, Catherine A., Evans, Allison N., Wright-Osment, Maureen K., Zajicek, James L., Heppell, Scott A., Riley, Stephen C., Krueger, Charles C., and Tillitt, Donald E.
Abstract:: Thiamine (vitamin B₁) deficiency is a global concern affecting wildlife, livestock, and humans. In Great Lakes salmonines, thiamine deficiency causes embryo mortality and is an impediment to restoration of native lake trout (Salvelinus namaycush) stocks. Thiamine deficiency in fish may result from a diet of prey with high levels of...

Surprises and Insights from Long-Term Aquatic Data Sets and Experiments

Creator:: Dodds, Walter K., Robinson, Christopher T., Gaiser, Evelyn E., Hansen, Gretchen J. A., Powell, Heather, Smith, Joseph M., Morse, Nathaniel B., Johnson, Sherri L., Gregory, Stanley V., Bell, Tisza, Kratz, Timothy K., and McDowell, William H.
Abstract:: Long-term research on freshwater ecosystems provides insights that can be difficult to obtain from other approaches. Widespread monitoring of ecologically relevant water-quality parameters spanning decades can facilitate important tests of ecological principles. Unique long-term data sets and analytical tools are increasingly available, allowing for powerful and synthetic analyses across sites....

Regional variation in mtDNA of the lesser prairie-chicken

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Wolfe, Don H., Robel, Robert J., Applegate, Roger D., and Oyler-McCance, Sara J.
Abstract:: Cumulative loss of habitat and long-term decline in the populations of the Lesser Prairie-Chicken (Tympanuchus pallidicinctus) have led to concerns for the species’ viability throughout its range in the southern Great Plains. For more efficient conservation past and present distributions of genetic variation need to be understood. We examined the...

Patterns of color phase indicate spawn timing at a Nassau grouper Epinephelus striatus spawning aggregation

Creator:: Archer, Stephanie K., Heppell, Scott A., Semmens, Brice X., Pattengill-Semmens, Christy V., Bush, Phillippe G., Mccoy, Croy M., and Johnson, Bradley C.
Abstract:: Nassau grouper Epinephelus striatus are a large bodied, top level predator that is ecologically important throughout the Caribbean. Although typically solitary, Nassau grouper form large annual spawning aggregations at predictable times in specific locations. In 2003, The Cayman Islands Marine Conservation Board established protection for a newly rediscovered Nassau grouper...
