Strategies for reducing risks from introductions of aquatic organisms: The federal perspective
James P. Clugston
1986, Fisheries (11) 26-29
The Lacey Act of 1900 and subsequent amendments have provided the basis for existing federal regulations on species introductions. The 1981 version repealed the Black Bass Act and corrected certain insufficiencies in the original Lacey and Black Bass Acts. A 1977 executive order instructs federal agencies, to the extent permitted...

Tissue distribution and elimination of radiolabelled methyltestosterone fed to sexually undifferentiated blue tilapia
C. A. Goudie, W. L. Shelton, N. C. Parker
1986, Aquaculture (58) 215-226
Populations of monosex male Oreochromis aureus can result when the synthetic androgen 17α-methyltestosterone (MT) is fed to sexually undifferentiated fish; however, concerns exist over residues of the androgen remaining in fish destined for human consumption. Radioactivity in the carcass and viscera was evaluated in juvenile fish fed steroid-incorporated diet (tritium and carbon-14...
Avian tuberculosis and salmonellosis in a whooping crane (Grus americana)
R. K. Stroud, C.O. Thoen, R. M. Duncan
1986, Journal of Wildlife Diseases (22) 106-110
The whooping crane has been the subject of intensive scientific study and management because it is an endangered species and has high public interest. Programs have been developed to identify critical habitat, to increase production through captive breeding, and in recent years, to use sandhill cranes (Grus canadensis) as surrogate...
Seed predation by yucca moths on semelparous, iteroparous and vegetatively reproducing subspecies of Yucca whipplei (Agavaceae)
Jon E. Keeley, Sterling C. Keeley, D. A. Ikeda
1986, American Midland Naturalist (115) 1-9
Yucca whipplei subspecies are distinguished by differences in reproduction: spp. whipplei and ssp. parishii are semelparous, flowering once and dying; ssp. caespitosa is iteroparous, producing multiple rosettes which may flower in different years; ssp. percursa has clonal reproduction from rhizomes, and ssp. intermedia is intermediate to the latter two. Seed...
The boundary model: A geographical analysis of design and conservation of nature reserves
C. Schonewald-Cox, J.W. Bayless
1986, Biological Conservation (38) 305-322
It is widely recognised that nearly all parks and reserves are too small to protect their biological diversity. In response to this problem, we have been developing a multidisciplinary ‘boundary model’ that focuses upon the processes of exchange across the administrative edges of nature reserves. The model incorporates known dynamics...
Tissue distribution and elimination of radiolabelled methyltestosterone fed to adult blue tilapia
C. A. Goudie, W. L. Shelton, N. C. Parker
1986, Aquaculture (58) 227-240
Radioactivity levels in 10 tissues were monitored for 21 days after adult (1-year-old) blue tilapia, Oreochromis aureus, were fed a single meal of a diet containing 30 μg unlabelled methyltestosterone (MT) per gram of feed and radiolabelled MT (3H-labelled steroid nucleus and 14C-labelled...
Mycoplasma contamination in fish cell lines: An evaluation of detection by differential incorporation of 3H-uridine and 14C-uracil
C. L. Schultz, B. C. Lidgerding, P. E. McAllister, F. M. Hetrick
1986, Journal of Fish Diseases (9) 117-122
Differential incorporation of uridine and uracil was used to assay for mycoplasma contamination in five fish cell lines: bluegill fry (BF-2), chinook salmon embryo (CHSE-214), epithelioma papillosum cyprini (EPC), fathead minnow (FHM) and rainbow trout gonad (RTG-2). The method was not suitable for monitoring BF-2, CHSE-214, FHM, and RTG-2 cell...
An incidence of twinning in the sea otter (Enhydra lutris)
Ronald J. Jameson, James L. Bodkin
1986, Marine Mammal Science (2) 305-309
On 3 October 1984 at 0928 h (PST) near Pt. San Simeon, California (35°39’N, 121°11’W), we observed a female sea otter (Enhydra lutris) resting in a kelp bed (Macrocystis pyrifera) with a small pup on her chest; approximately 2 m away another small pup floated unattended in the kelp. The...

Diet related anemia in channel catfish: Case history and laboratory induction
G. T. Klar, L. A. Hanson, S. W. Brown
1986, Progressive Fish-Culturist (48) 60-64
Severe anemia among fingerling to adult channel catfish (Ictalurus punctatus) and blue catfish (Ictalurus furcatus) was reported by 39 of 166 catfish farmers in west‐central Alabama in 1983. The hematocrits of moribund fish in ponds ranged from 0 to 5%. Weekly mortalities as high as 5% in individual ponds were...

A field guide to valuable underwater aquatic plants of the Great Lakes
Donald W. Schloesser
1986, Report
Underwater plants are a valuable part of the Great Lakes ecosystem, providing food and shelter for aquatic animals. Aquatic plants also help stabilize sediments, thereby reducing shoreline erosion. Annual fall die-offs of underwater plants provide food and shelter for overwintering small aquatic animals such as insects, snails, and freshwater shrimp. In...
Applications of Landsat data and the data base approach

1986, Photogrammetric Engineering and Remote Sensing (52) 1193-1199
A generalized methodology for applying digital Landsat data to resource inventory and assessment tasks is currently being used by several bureaux and agencies within the US Department of the Interior. The methodology includes definition of project objectives and output, identification of source materials, construction of the digital data base, performance...
Temperature effects on kerogen and on molecular and isotopic composition of organic matter in Pierre Shale near an igneous dike
J.L. Clayton, N. H. Bostick
1986, Organic Geochemistry (10) 135-143
A suite of siltstone samples from the Upper Cretaceous Pierre Shale from the contact zone of a 130-cm thick igneous dike near Wolcott, Colorado, U.S.A., was taken from the contact to 170 cm from the dike to study the effects of temperature on the organic matter. The sampled bedding interval...
Geochemical correlation of surface and subsurface oils, western Greece
J. G. Palacas, D. Monopolis, C.A. Nicolaou, D.E. Anders
1986, Organic Geochemistry (10) 417-423
Biodegraded seep oils, devoid of n-alkanes and most isoprenoid hydrocarbons, were successfully correlated with subsurface crude oils in western Greece primarily using carbon isotopes and the more microbially resistant tricyclic terpane and aromatic steroid hydrocarbon distributions. All the studied oils seem to fit into three major genetic groups which are...
EVIDENCE FOR THREE MODERATE TO LARGE PREHISTORIC HOLOCENE EARTHQUAKES NEAR CHARLESTON, S. C.
Robert E. Weems, Stephen F. Obermeier, Milan J. Pavich, Gregory S. Gohn, Meyer Rubin, Richard L. Phipps, Robert B. Jacobson
1986, Conference Paper
Earthquake-induced liquefaction features (sand blows), found near Hollywood, S. C. , have yielded abundant clasts of humate-impregnated sand and sparse pieces of wood. Radiocarbon ages for the humate and wood provide sufficient control on the timing of the earthquakes that produced the sand blows to indicate that at least three...
Distribution of anomalously high K2O volcanic rocks in Arizona: metasomatism at the Picacho Peak detachment fault
W. E. Brooks
1986, Geology (14) 339-342
Metasomatized Tertiary lavas with anomalously high K2O and low Na2O content are distributed within the northwest-trending Miocene extensional terrane of southwestern Arizona. These rocks are common near core-complex–related detachment faults at Picacho Peak and the Harcuvar Mountains and in listric-faulted terrane at the...
