Three closely related herpesviruses are associated with fibropapillomatosis in marine turtles
S.L. Quackenbush, Thierry M. Work, George H. Balazs, Rufina N. Casey, J. Rovnak, A. Chaves, L. duToit, J.D. Baines, C.R. Parrish, Paul R. Bowser, James W. Casey
1998, Virology (246) 392-399
Green turtle fibropapillomatosis is a neoplastic disease of increasingly significant threat to the survivability of this species. Degenerate PCR primers that target highly conserved regions of genes encoding herpesvirus DNA polymerases were used to amplify a DNA sequence from fibropapillomas and fibromas from Hawaiian and Florida green turtles. All of...
Relationship of lake herring (Coregonus artedi) gill raker characteristics to retention probabilities of zooplankton prey
Jason Link, Michael H. Hoff
1998, Journal of Freshwater Ecology (13) 55-65
We measured morphometric and meristic parameters of gill rakers from the first gill arch of 36 adult lake herring (Coregonus artedi) from Lake Superior that ranged in length from 283–504 mm. These data, coupled with the mean of the smallest two body dimensions (length, width, or breadth) of various zooplankton...
Estimates of loss rates of jaw tags on walleyes
Steven P. Newman, Michael H. Hoff
1998, North American Journal of Fisheries Management (18) 202-205
The rate of jaw tag loss was evaluated for walleye Stizostedion vitreum in Escanaba Lake, Wisconsin. We estimated tag loss using two recapture methods, a creel census and fykenetting. Average annual tag loss estimates were 17.5% for fish recaptured by anglers and 27.8% for fish recaptured in fyke nets. However, fyke-net data...

Fish community changes in the St. Louis River estuary, Lake Superior, 1989-1996: Is it ruffe or population dynamics?
Charles R. Bronte, Lori M. Evrard, William P. Brown, Kathleen R. Mayo, Andrew J. Edwards
1998, Journal of Great Lakes Research (24) 309-318
Ruffe (Gymnocephalus cernuus) have been implicated in density declines of native species through egg predation and competition for food in some European waters where they were introduced. Density estimates for ruffe and principal native fishes in the St. Louis River estuary (western Lake Superior) were developed for 1989 to 1996...
Sexual difference in polychlorinated biphenyl accumulation rates of walleye (Stizostedion vitreum)
Charles P. Madenjian, George E. Noguchi, Robert C. Haas, Kathrin S. Schrouder
1998, Canadian Journal of Fisheries and Aquatic Sciences (55) 1085-1092
Adult male walleye (Stizostedion vitreum) exhibited significantly higher polychlorinated biphenyl (PCB) concentrations than similarly aged female walleye from Saginaw Bay (Lake Huron). To explain this difference, we tested the following three hypotheses: (i) females showed a considerably greater reduction in PCB concentration immediately following spawning than males, (ii) females...

Sieve efficiency in benthic sampling as related to chironomid head capsule width
Patrick L. Hudson, Jean V. Adams
1998, Journal of the Kansas Entomological Society (71) 456-468
The width of the head capsule in chironomid larvae is the most important morphometric character controlling retention of specimens in sieving devices. Knowledge of the range in size of these widths within any chironomid community is fundamental to sampling and interpreting the resulting data. We present the head capsule widths...
