High-performance liquid chromatography of quinoidal imminium compounds derived from triphenylmethanes
S. L. Abidi
1983, Journal of Chromatography (255) 101-114
A series of eleven p-aminotriphenylmethane dyes have been studied by high-performance liquid chromatography (HPLC). The combined use of HPLC and spectrophotometry permits specific detection of these compounds in the visible range around 600 nm. As the high affinity of the imminium cations for the active sites of the hydrocarbonaceous stationary...
The use of albendazole for the treatment of trematodiasis in two tree shrews (Tupala glis)
B.A. Beehler, B.N. Tuggle
1983, Journal of Zoo Animal Medicine (14) 61-63
Albendazole is a broad-spectrum anthelmintic of the benzimidazole group which has been tested in several rodents and domestic animals. Albendazole has been used effectively to treat trematodes in sheep, cattle, dogs, and cats. The use of this anthelmintic in exotic small mammals has not been reported to the authors' knowledge....

William D. Swink
1983, Fisheries (8) 5-9
A mail survey of fisheries agencies in the United States showed that 207.7 million nonmigratory salmonids were stocked in 1980 in the waters of 47 states (exclusive of the Great Lakes). Stocking in tailwaters accounted for 6.9 million or 3.3% of the total. In the South, 32.3% of all salmonids...

J. Christian Franson, James W. Spann, Gary Heinz, Christine M. Bunck, Thair Lamont
1983, Archives of Environmental Contamination and Toxicology (12) 529-534
Forty-four pairs of game-farm mallards (Anas platyrhynchos) were fed ABATE® 4E (temephos) to yield 0, 1, or 10 ppm ABATE® beginning before the initiation of lay, and terminating when ducklings were 21 days of age. The mean interval between eggs laid was greater for hens fed 10 ppm...
Effects on birds of fenthion aerial application for mosquito control
L.R. DeWeese, L. C. McEwen, L.A. Settimi, R.D. Deblinger
1983, Journal of Economic Entomology (76) 906-911
Effects on birds of an aerial application of fenthion, a potent organophosphorus cholinesterase (ChE)-inhibiting insecticide, were assessed on four study sites 1.8 to 3.6 km2 in size. These sites were located within 121.5 km2 of wet meadows treated with 47 g of fenthion (AI) per ha in ultra-low-volume formulation. Assessment methods were...
Distribution and ecology of marine turtles in waters off the southeastern United States
T. H. Fritts, W. Hoffman, M.A. McGehee
1983, Journal of Herpetology (17) 327-344
Aerial surveys of marine waters up to 222 km from shore in the Gulf of Mexico and nearby Atlantic Ocean suggest that marine turtles are largely distributed in waters less than 100 m in depth. The loggerhead turtle (Caretta caretta) was observed nearly 50 times as often in waters off...

Feeding habitats of nesting wading birds: Spatial use and social influences
R. Michael Erwin
1983, The Auk (100) 960-970
In an effort to relate social interactions to feeding-habitat use, I observed six species of wading birds near a major colony site in coastal North Carolina. Three spatial scales of habitat use were considered: the general orientation to and from the colony (coarsest level), the habitat "patch," and (at the...
Year and age effects on residues of dieldrin and heptachlor in dead gray bats, Franklin County, Missouri— 1976, 1977, and 1978
D. R. Clark Jr., C.M. Bunck, E. Cromartie, R. K. LaVal
1983, Environmental Toxicology and Chemistry (2) 387-393
Dead gray bats (Myotis grisescens) containing lethal concentrations of dieldrin were found beneath a maternity roost in Bat Cave Nos. 2 and 3, Franklin County, Missouri, in 1976, 1977 and 1978. Whereas residues of dieldrin, DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene] and PCB polychlorinated biphenyls in bats appeared not to change significantly over the...
DDE in brown and white fat of hibernating bats
D. R. Clark Jr., A. J. Krynitsky
1983, Environmental Pollution (Series A) (31) 287-299
Samples of brown and white fat from hibernating bats (big brown bat, Eptesicus fuscus; little brown bat, Myotis lucifugus; and eastern pipistrelle, Pipistrellus subflavus) collected in western Maryland, USA, were analysed to determine lipid and DDE content. Amounts of brown fat, expressed as percentages of...

Fifty-ninth Christmas Bird Count. 176. Ocean City, Md
C.S. Robbins
1983, American Zoologist (23) 129
Some organophosphorus insecticides have been reported to interfere with reproduction and even cause the decline of small mammal populations. The effects of such anticholinesterases on plasma LH concentrations were examined in male mice (Peromyscus leucopus noveboracensis) intubated with water (OW) or acephate (50 and 100 mg/kg) and sacrificed after...
FLIT-MLO and No. 2 fuel oil: Effects of aerosol applications to mallard eggs on hatchability and behavior of ducklings
P.H. Albers, G. H. Heinz
1983, Environmental Research (30) 381-388
FLIT-MLO and No. 2 fuel oil are sprayed on wetlands for mosquito control during spring and summer. In one experiment to assess the effects of the spraying on birds, mallard eggs were sprayed with amounts of No. 2 fuel oil equivalent to 2.34, 4.67, or 18.70 liters/ha or FLIT-MLO equivalent...
Empirical comparison of uniform and non-uniform probability sampling for estimating numbers of red-cockaded woodpecker colonies

1983, American Statistical Association, Proceedings of the Section on Survey Research Methods (1983) 144-149
Four sampling and estimation methods for estimating the number of red-cockaded woodpecker colonies on National Forests in the Southeast were compared, using samples chosen from simulated populations based on the observed sample. The methods included (1) simple random sampling without replacement using a mean per sampling...

1983, Southwestern Naturalist (28) 325-333
A potential organochlorine pesticide problem was identified near Mission, Texas, by the National Pesticide Monitoring Program. Fish samples from this site have consistently contained elevated levels of DDE since 1968. Surveys were made in 1976, 1978, and 1979 to determine the extent of organochlorine pesticide contamination in fishes and birds...
