Efforts to restore lake trout (Salvelinus namaycush) in Lake Huron after their collapse in the 1940s were underway in the early 1970s with completion of the first round oflampricide applications in tributary streams and the stocking of several genotypes. We assess results of rehabilitation and establish a historical basis for comparison by quantifying the catch of spawning lake trout from Michigan waters in 1929-1932. Sixty-eight percent of this catch occurred in northern waters (MH-1) and most of the rest (15%) was from remote reefs in the middle of the main basin. Sea lampreys (Petromyzon mari-nus) increased in the early 1980s in the main basin and depressed spawning populations of lake trout. This increase was especially severe in northern waters and appeared to be associated with untreated populations in the St. Marys River. Excessive commercial fishing stemming from unresolved treaty rights also contributed to loss of spawning fish in northern Michigan waters. Seneca-strain lake trout did not appear to be attacked by sea lampreys until they reached a size > 532 mm. At sizes > 632 mm, Seneca trout were 40-fold more abundant than the Marquette strain in matched-planting experiments. Natural reproduction past the fry stage has occurred in Thunder Bay and South Bay, but prospects for self-sustaining populations of lake trout in the main basin are poor because sea lampreys are too abundant, only one side of the basin is stocked, and stocking is deferred to allow commercial gillnetting in areas where most of the spawning occurred historically. Backcross lake trout, a lake trout x splake (S. fontinalis x S. namaycush) hybrid, did not reproduce in Georgian Bay, but this genotype is being replaced with pure-strain lake trout, whose early performance appears promising.

Survival to hatch was significantly higher in the laboratories and averaged 80.9%. In Lake Superior, egg survival among incubators at all sites was significantly higher (P < 0.0001) for incubators that remained buried in spawning substrates (15.1–21.0%) than for incubators that were partially or completely exposed to water currents (1.0–12.6%). Egg survival for incubators that remained buried at the shallow-water sites was significantly higher at Bark Point (44.6%) than at Gull Island Shoal (21.0%). Egg survival among incubators that remained buried at the deep (14.4%) and shallow-water sites (21.0%) on Gull Island Shoal was not significantly different. Because incubators that were completely buried or partially exposed only appeared to differ in their degree of exposure, we concluded that survival of eggs in the lake was reduced by mechanical stress associated with water turbulence. Lower egg survival at Gull Island Shoal, a known lake trout-spawning site, was not expected and appeared to have been caused by a strong gale that occurred when these eggs were in late epiboly, a sensitive embryological stage. We present a hypothesis suggesting that lake trout recruitment in the Great Lakes is limited by availability of spawning habitat.

Applications of the model to biogeochemical studies are also envisaged. The model has been used to simulate daily-averaged salinity in the upper and lower levels of a 51-segment discretization of the Bay over the 22-y period 1967–1988. Observed, monthly-averaged surface salinity data and monthly averages of the daily-simulated salinity are in reasonable agreement, both near the Golden Gate and in the upper reaches, close to the delta. Agreement is less satisfactory in the central reaches of North Bay, in the vicinity of Carquinez Strait. Comparison of daily-averaged data at Station 5 (Pittsburg, in the upper North Bay) with modeled data indicates close agreement with a correlation coefficient of 0.97 for the 4110 daily values. The model successfully simulates the marked seasonal variability in salinity as well as the effects of rapidly changing freshwater inflows. Salinity variability is driven primarily by freshwater inflow. The sensitivity of the modeled salinity to variations in the longitudinal mixing coefficients is investigated. The modeled salinity is relatively insensitive to the calibration factor for vertical mixing and relatively sensitive to the calibration factor for longitudinal mixing. The optimum value of the longitudinal calibration factor is 1.1, compared with the physically-based value of 1.0. Linear time-series analysis indicates that the observed and dynamically-modeled salinity-inflow responses are in good agreement in the lower reaches of the Bay.

Their unique physiographic position gives rise to large spatial variability, and to dynamic temporal variability resulting, in part, from a variety of forces and fluxes at the oceanic and terrestrial boundaries. River flow, in particular, is an important mechanism for delivering watershed-derived materials such as fresh water, sediments, and nutrients; each of these quantities in turn directly influences the physical structure and biological communities of estuaries. With this setting in mind, we consider here the general proposition that estuarine variability at the yearly time scale can be caused by annual fluctuations in river flow. We use a “long-term” (15-year) time series of phytoplankton biomass variability in South San Francisco Bay (SSFB), a lagoon-type estuary in which phytoplankton primary production is the largest source of organic carbon (Jassby et al. 1993).

Application of this contactor type in closed culture systems is attractive given its insensitivity to biological fouling and ability to operate without the need for a significant hydraulic gradient. Performance algorithms were developed through application of chemical reactor theory, Henry's Law and the Ideal Gas Law. In the analysis, gas and liquid phases were treated as being homogeneous. The design steps presented are unique in that required mass transfer coefficients (KLa), operating pressures (CP), and oxygen feed rates (G/L) are calculated for target changes in both dissolved oxygen and nitrogen without the use of iterative numerical procedures. A second calculation sequence establishes the sensitivity of system performance to changes in G/L when CP and KLa are known.

At Glacier Bay National Park, the Margerie Glacier colony was censused visually in 1991 through 1993. In 1993 a new photographic census technique was also tested to assess its feasibility, accuracy, and ease of use, Three years of monitoring data indicate that kittiwake population size declined by about 10% over the three-year period, and that there were near-total colony reproductive failures in 1991 and 1992. Compared to visual colony counts made from a skiff, counting adult kittiwakes from projected 35-mm slides proved to be both more efficient and equally accurate.

Vegetation change was monitored for 8 yr using plots and for 30 yr using aerial photographs. A 20th century fire history was reconstructed from the stand structure of multiple-stemmed trees and fire scars. General Land Office Survey data were used to reconstruct the forest of A.D. 1834. Fossil pollen and charcoal records were used to reconstruct the last 4000 yr of vegetation and fire history.
Since its deposition along the shore of Lake Michigan about 4000 yr ago, the area has followed a classical primary dune successional sequence, gradually changing from pine forest to prairie/oak savanna between A.D. 264 and 1007. This successional trend, predicted in the models of Henry Cowles, occurred even though the climate cooled and prairies elsewhere in the region retreated. Severe fires in the 19th century reduced most tree species but led to a temporary increase in Populus tremuloides. During the last few decades, the prairie has been invaded by oaks and other woody species, primarily because of fire suppression since A.D. 1972.
The rapid and complex changes now occurring are a response to the compounded effects of plant succession, intense burning and logging in the 19th century, recent fire suppression, and possibly increased airborne deposition of nitrates. The compilation of several historical research techniques emphasizing different time scales allows this study of the interactions between multiple disturbance variables.

Mean solid bitumen reflectance ranges from about 2.4 to 2.7% and shows little change up to 6 m away from the dike contact. Carbon and oxygen isotope values also show little change except at the dike contact. The most detectable response of the rock to contact metamorphism is the proportion of solid bitumen grains with finely granular mosaic structure increase towards the dike. Also under cathodoluminescence (CL) excitation, the host rock is initially observed to be recrystallized to a uniform bright orange color. By 1 cm away from the contact, however, CL shows preservation of sharp boundaries in finely zoned burial cements. A regional study of thermal maturation and a geothermometer based on solid bitumen reflectance indicate paleotemperatures near 200°C were widespread in the Buchan Rift during peak burial near the time of the Devonian Tabberabberan Deformation. The lack of response of the Buchan Caves Limestone to contact metamorphism is attributed to: (1) prior heating to near 200°C; and (2) the fact that the dike intruded into cool, near surface, low-porosity rocks which may have been in the vadose zone.

Ground-water discharges into and total drain-water discharges from individual dry docks were computed from a single set of discharges of individual inflowing drains' and outflowing drain-water collection culverts that were measured in June, July and August 1994. Ground-water inflows to dry docks no. 1, 2, 3, 4, 5, and 6 equalled 0.07, 0.30, 0.29, 0.61, 1.18, and 6.2 cubic feet per second, respectively, and total drain-water discharges from the dry docks equalled 0.07, 0.30, 0.33, 0.61, 1.36, and 11.7 cubic feet per second, respectively. The differences between total outflows and ground-water inflows were mostly cofferdam and floodgate leakage and cooling water from a ship in dry dock no. 6. Observed salinities indicate that 18, 92, 28, 44, 55, and 69 percent of the ground-water inflows to dry docks no. 1 through 6 and 18, 92, 37, 44, 63, and 82 percent of the total outflows from the dry docks was saline water from Sinclair Inlet.
Concentrations of total copper in samples from 36 sites varied from less than 1 to 71 micrograms per liter, and concentrations of total lead varied from less than 1 to 44 micrograms per liter. None of 43 semi-volatile organic compounds that were analyzed for in samples from 19 sites were detected at concentrations greater than the laboratory minimum reporting level (5 or 10 micrograms per liter). A total of 13 volatile organic compounds were found at concentrations greater than laboratory minimum reporting levels (mostly 0.2 microgram per liter) in 8 samples that were analyzed for 63 volatile organic compounds. Trichloroethene and at least three other chlorinated hydrocarbons were found in each sample.

The minute (average in situ cell size, 2 to 3 μm) flagellates, which are relatively abundant in the Cape Cod aquifer, were isolated from core samples, grown in a grass extract medium, labeled with hydroethidine (a vital eukaryotic stain), and coinjected into aquifer sediments along with bromide, a conservative tracer. The 2-μm flagellates appeared to be near the optimal size for transport, judging from flowthrough column experiments involving a polydispersed (0.7 to 6.2 μm in diameter) suspension of carboxylated microspheres. However, immobilization within the aquifer sediments accounted for a log unit reduction over the first meter of travel compared with a log unit reduction over the first 10 m of travel for indigenous, free-living groundwater bacteria in earlier tests. High rates of flagellate immobilization in the presence of aquifer sediments also was observed in the laboratory. However, immobilization rates for the laboratory-grown flagellates (initially 4 to 5 μm) injected into the aquifer were not constant and decreased noticeably with increasing time and distance of travel. The decrease in propensity for grain surfaces was accompanied by a decrease in cell size, as the flagellates presumably readapted to aquifer conditions. Retardation and apparent dispersion were generally at least twofold greater than those observed earlier for indigenous groundwater bacteria but were much closer to those observed for highly surface active carboxylated latex microspheres. Field and laboratory results suggest that 2-μm carboxylated microspheres may be useful as analogs in investigating several abiotic aspects of flagellate transport behavior in groundwater.

Our empirical observations indicated that 12% of fish in age-class 4, 34% of fish in age-class 5, and 77% of fish in age-class 6 were mature. The estimate of the proportion of mature fish in age-class 5 differs significantly from that of Merriman (1941), who also examined coastal migrants. No significant differences were found in maturity estimates of fish from stocks of different origin.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"London, UK","doi":"10.1577/1548-8659(1995)124<0207:AAMEFA>2.3.CO;2","usgsCitation":"Berlinsky, D.L., Fabrizio, M.C., O'Brien, J., and Specker, J.L., 1995, Age-at-maturity estimates for Atlantic coast female striped bass: Transactions of the American Fisheries Society, v. 124, no. 2, p. 207-215, https://doi.org/10.1577/1548-8659(1995)124<0207:AAMEFA>2.3.CO;2.","productDescription":"8 p.","startPage":"207","endPage":"215","numberOfPages":"8","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":486885,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.uri.edu/gsofacpubs/2522","text":"External Repository"},{"id":134095,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266948,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8659(1995)124<0207:AAMEFA>2.3.CO;2"}],"volume":"124","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae3e4b07f02db68925a","contributors":{"authors":[{"text":"Berlinsky, David L.","contributorId":90270,"corporation":false,"usgs":true,"family":"Berlinsky","given":"David","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":309383,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fabrizio, Mary C.","contributorId":77471,"corporation":false,"usgs":true,"family":"Fabrizio","given":"Mary","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":309382,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"O'Brien, John F.","contributorId":36511,"corporation":false,"usgs":true,"family":"O'Brien","given":"John F.","affiliations":[],"preferred":false,"id":309381,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Specker, Jennifer L.","contributorId":106849,"corporation":false,"usgs":true,"family":"Specker","given":"Jennifer","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":309384,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70019592,"text":"70019592 - 1995 - Methylmercury oxidative degradation potentials in contaminated and pristine sediments of the Carson River, Nevada","interactions":[],"lastModifiedDate":"2023-01-17T19:31:03.893216","indexId":"70019592","displayToPublicDate":"1995-01-01T00:00:00","publicationYear":"1995","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":850,"text":"Applied and Environmental Microbiology","active":true,"publicationSubtype":{"id":10}},"title":"Methylmercury oxidative degradation potentials in contaminated and pristine sediments of the Carson River, Nevada","docAbstract":"Sediments from mercury-contaminated and uncontaminated reaches of the Carson River, Nevada, were assayed for sulfate reduction, methanogenesis, denitrification, and monomethylmercury (MeHg) degradation. Demethylation of [14C]MeHg was detected at all sites as indicated by the formation of 14CO2 and 14CH4. Oxidative demethylation was indicated by the formation of 14CO2 and was present at significant levels in all samples. Oxidized/reduced demethylation product ratios (i.e., 14CO2/14CH4 ratios) generally ranged from 4.0 in surface layers to as low as 0.5 at depth. Production of 14CO2 was most pronounced at sediment surfaces which were zones of active denitrification and sulfate reduction but was also significant within zones of methanogenesis. In a core taken from an uncontaminated site having a high proportion of oxidized, coarse-grain sediments, sulfate reduction and methanogenic activity levels were very low and 14CO2 accounted for 98% of the product formed from [14C]MeHg. There was no apparent relationship between the degree of mercury contamination of the sediments and the occurrence of oxidative demethylation. However, sediments from Fort Churchill, the most contaminated site, were most active in terms of demethylation potentials. Inhibition of sulfate reduction with molybdate resulted in significantly depressed oxidized/reduced demethylation product ratios, but overall demethylation rates of inhibited and uninhibited samples were comparable. Addition of sulfate to sediment slurries stimulated production of 14CO2 from [14C]MeHg, while 2-bromoethanesulfonic acid blocked production of 14CH4. These results reveal the importance of sulfate-reducing and methanogenic bacteria in oxidative demethylation of MeHg in anoxic environments.
