Fisheries Report No 57 - Exploratory Fishing For Spanish Mackerel In Waters Off Western Australia During The Period June 16 To October 16, 1981, K. Donohue, P. Edsall, J. Robins, R. Tregonning
Fisheries Research Reports
The results of catching Spanish mackerel (Scomberomorus commerson) by gillnet and troll lines during a survey extending from June 16 to October 16 1981 are presented.
The catch rate of mackerel obtained by trolling with six lines was found to be 14.35 times greater than that by gillnet, measuring 0.75 miles in length.
From the results presented, a professional fisherman should be able to assess the economic viability of fishing commercially for Spanish mackerel.
Analysis of biometrial and biological data on fish caught allowed determination of (a) length/weight relationship of (i) Spanish mackerel (ii) wahoo (Acanthocybium solandri); (b) sex ratios …

Report No 56 - 1981 Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro
Fisheries Research Reports
An account is given of the biological principles involved in decisions concerning duck-shooting seasons in the south-west of Western Australia.
The conditions for waterfowl which prevailed during 1981 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.
Rainfall was generally average over central and northern areas of the south-west during 1981. Rainfall in southern areas, however, was generally
below to much-below-average, although south coastal areas from Augusta to Albany received average falls.
Unusually heavy falls were recorded in North Coastal, North Central and Central Coastal Districts in May, and average falls were …

Interactions Of Northern Fur Seals And Commercial Fisheries, Charles W. Fowler
Interactions Of Northern Fur Seals And Commercial Fisheries, Charles W. Fowler
United States Department of Commerce: Staff Publications
Under international agreement, the northern fur seal (Callorhinus ursinus) is managed with the objective of obtaining a maximum sustainable yield. Currently the harvest is restricted to subadult males; however, between 1956 and 1968 the fur seal population of the Pribilof Islands was subjected to a harvest of females. This harvest was justified, in part, as an attempt to stimulate the production of greater quantities of harvestable animals (Chapman 1981). A reduction in the population occurred during this period as can be seen in Figure 1. As described in York and Hartley (1981), the female harvest itself provides an …

Conservation Measures In The Interim Fishery Management Plan For Atlantic Groundfish, Andrew P. Matykiewicz
Conservation Measures In The Interim Fishery Management Plan For Atlantic Groundfish, Andrew P. Matykiewicz
Marine Affairs Theses and Major Papers
The conservation measures used in the Interim Fishery Management Plan for Atlantic Groundfish (IFMP) were analyzed. The management techniques used include a minimum mesh size, minimum fish size and haddock spawning area closure. However the mesh regulation does not adequately address the IFMP conservation objectives. Without amendment, the IFMP cannot prevent overfishing as it is required to do by the Magnuson Fishery Conservation and Management Act (MFCMA). The use of a non-numeric Optimum Yield (OI) for groundfish is inappropriate without a definition of overfishing and without a contingency plan to prevent overfishing.

Threshold Friction Velocities And Rupture Moduli For Crusted Desert Soils For The Input Of Soil Particles Into The Air, Dale A. Gillette, John Adams, Daniel R. Muhs, Rolf Kihl
United States Geological Survey: Staff Publications
Desert soils having clay crusts, mostly from the Mojave Desert, were tested for threshold friction velocity (the friction velocity at which soil erosion begins) with an open-bottomed wind tunnel. The soils were also tested for content of clay, water-soluble material, calcium carbonate, organic material, mineralogy of clay and of salts, soil moisture, modulus of rupture, and crust thickness. If no loose material existed on the soil surface, crusts having modulus of rupture greater than 0.7 bar and crust thickness of 0.7 cm to 0.3 cm were effective in protecting against wind erosion. Disturbed clay crusts having modulus of rupture before …

Comparison Of Proton Transfers In Cationic Heterodimers And Homodimers Of Nh3 And Oh2, Steve Scheiner
Chemistry and Biochemistry Faculty Publications
Ab initio molecular orbital methods are used to study proton transfers in the cationic heterodimer (H3NHOH2)+ as well as the symmetric homodimers (H2OHOH2)+ and (H3NHNH3)+. All calculations are carried out at the Hartree–Fock level with a 4‐31G basis set to ensure consistency. For proton transfers along a linear hydrogen bond in the heterodimer, asymmetric single‐well potentials with a minimum corresponding to (NH4)+(OH2) are obtained for R(NO) distances of less than 2.85 …
Primary Production In Tampa Bay, Florida: A Review, J.O. R. Johansson
Primary Production In Tampa Bay, Florida: A Review, J.O. R. Johansson
Reports
Primary production data for Tampa Bay is very limited. The phytoplankton component has received the greatest study effort; however, even knowledge of this group is limited and biased by the lack of area-wide and long-term studies, and the use of questionable methodologies. This review will summarize historical primary production data; discuss methodologies and their shortcomings; outline future research needs for understanding the carbon cycle of the Tampa Bay system; and discuss the carbon cycle in relation to trophic dynamics.

Restoring Natural Conditions In A Boreal Forest Park, Glen F. Cole
United States National Park Service: Publications
Voyageurs National Park is located in northern Minnesota (Figure 1). Its northern and eastern boundaries parallel a historic fur trade route that influenced the location of the boundary between the United States and Canada. About two-thirds of the park's 344-square-mile (891 km2) area is land, and the remainder is made up of numerous small and large lakes. The interspersion of forested land, massive rock outcrops and lakes make the park very scenic. It is also somewhat unique because it is the only U.S. park on the mainland in a southern boreal forest region. Isle Royale National Park is …
Management Of Roosevelt Elk Habitat And Harvest, E. E. Starkey, D. S. Decalesta, G. W. Witmer
Management Of Roosevelt Elk Habitat And Harvest, E. E. Starkey, D. S. Decalesta, G. W. Witmer
United States National Park Service: Publications
Historically, Roosevelt elk (Cervus elaphus roosevelti) were distributed from northern California to southern British Columbia in the coastal Pacific Northwest. During the Pleistocene, the subspecies was isolated reproductively from the Rocky Mountain elk (C. e. nelsoni) to the east by the Cascade Mountain Range and by glaciation (Guthrie 1966). Thus Roosevelt elk have adapted to relatively moist forest habitats with maritime climates, while Rocky Mountain elk evolved under the continental climate of the interior.
Unfortunately, less is known of Roosevelt elk biology than of the closely related Rocky Mountain elk east of the Cascades. This has …

Electrochemical Determination Of The Heterogeneous Electron Transfer Kinetics Of Soluble Spinach Ferredoxin, Charlene D. Crawley
Electrochemical Determination Of The Heterogeneous Electron Transfer Kinetics Of Soluble Spinach Ferredoxin, Charlene D. Crawley
Theses and Dissertations
The application of electrochemical techniques to biological systems has become an attractive method for characterizing the redox and electron transfer behavior of biomacromolecules. This study focuses on the role of soluble spinach ferredoxin (Fd) in photosynthesis where it functions as an electron carrier to membrane bound species in the plant chloroplast. An electrochemical model is used where in Fd now serves as a soluble redox species which undergoes oxidation and reduction via electron transfer at an electrode. This type of model is significant in that both the membrane and electrode reactive sites are characterized by charged bilayer interfacial regions which …

Great Blue Heron Nesting Biology And Habitat Use On The James River In South Dakota, Eileen M. Dowd
Electronic Theses and Dissertations
Breeding biology, nest site activities, and habitat use of great blue herons (Ardea herodias) nesting in the Glendale heronry, South Dakota, were investigated in 1980 and 1981. Mean brood size was 3.35 nestlings. The predicted number of feeding trips of adult birds peaked when nestlings were 29 days old. A significant amount of variance in adult feeding trips per hour was accounted for by southerly winds and the time period from 1800-2100 hours. The variables that were not significantly related to the number of feeding trips were temperature, wind speed, wind directions other than south, cloud cover, and the 4 …

Walleyes exhibited a seasonal distribution pattern; inhabiting the discharge area during the cooler months and the intake area during the warmer months, Summer-fall home ranges of three walleyes were estimated, Maximum home ranges (maximum area covered by an individual) were overlapping and similar in size, ranging from 36, 7-45, 9 ha, Estimates of utilized areas (intensively …
Aquatic Plant Communities And Invertebrates In A Prairie Pothole During Duck Brood Rearing, Jeffrey W. Mccrady
Aquatic Plant Communities And Invertebrates In A Prairie Pothole During Duck Brood Rearing, Jeffrey W. Mccrady
Electronic Theses and Dissertations
More than 1,100 samples of aquatic plants and associated invertebrates were collected in a prairie wetland. Sampling was done weekly throughout the duck brood rearing season. Linear regression revealed a 4 to 100 ratio of animal to plant biomass (R²=0.488). Comparatively high degrees of association were found between Ceratophyllum demersum and Gastropoda and between Lemna minor and most zooplankton groups. Significant sources of variation in invertebrate biomass were plant communities, date, plants, and community by date interaction. Depth and communities were not significant.

Food Habits And Placental Scar Counts Of Bobcats In South Dakota, David Eric Nomsen
Electronic Theses and Dissertations
Bobcat (Lynx rufus) food habits and placental scar counts were investigated in western South Dakota during 1978-79 and 1979-80 trapping and hunting seasons. Food habits were recorded by frequency of occurrence and placental scar counts were used to determine litter size for South Dakota bobcats. Rabbits (Sylvilagus spp. and Lepus spp.), rats and mice (primarily Microtus spp. and Peromyscus spp.), and deer (Odocoileus spp.) were identified in 56, 32, and 7% of bobcat stomachs, respectively. Analysis showed that rabbits, rats and mice, and deer occurred in 58, 36, and 9% of bobcat intestines, respectively. Occurrences in rabbits decreased from 67% …

Samples of star duckweed (Lemna trisulca L.) were collected from a South Dakota prairie wetland during the summer 1981. Amphipods and gastropods were the dominant macroinvertebrates found within samples of duckweed in terms of biomass and density. Cladocera were the dominant microinvertebrates found in association with star duckweed. Significant variability was found in the biomass and densities of specific invertebrates with respect to sampling dates. Crude protein values of star duckweed-invertebrate community samples ranged from 7.6 to 18.5% and were found to correlate significantly with protein levels of the duckweed. Crude protein values for star duckweed ranged from 7.1 to …
