The Demography Of Doublegee. Ecological Studies On Arum Lily., F. D. Panetta
The Demography Of Doublegee. Ecological Studies On Arum Lily., F. D. Panetta
Experimental Summaries - Plant Research
3.1 Growth of doublegees under summer irrigation. (87A40)
The weevil, Perapion antiquum is a potential biological control agent of doublegee. However, it exhibits large population crashes during the summer months in the summer-dry areas of the Western Caped of South Africa, where it is native. It has been suggested that one means of successfully establishing Perapion in Western Australia could be to maintain populations in 'oases' over the summer months. The aim of this experiment was to determine how readily doublegee could be maintained in a non-senescent phase under irrigated and shaded conditions.

Pesticide Use And Toxicology In Relation To Wildlife: Organophosphorus And Carbamate , Compounds, Gregory J. Smith, U.S. Department Of The Interior, Fish And Wildlife Service
All U.S. Government Documents (Utah Regional Depository)
The use of organophosphorus and carbamate pesticides has increased markedly during the past two decades. Currently, more than 100 different organophosphorus and carbamate chemicals are registered as the active ingredients in thousands of different pesticide products in the United States. More than 160 million acre-treatments of these pesticides are estimated to be applied to agricultural crops and forests each year. Clearly, these two groups of chemicals constitute a major portion of all pesticides used today. Organophosphorus and carbamate compounds have histories dating back long before their use as pesticides. Carbamates were developed during investigation of "ordeal" poisons used in Africa …
Container-Grown Ponderosa Pine Seedlings Outperform Bareroot Seedlings On Harsh Sites In Southern Utah, United States Department Of Agriculture, Forest Service
Container-Grown Ponderosa Pine Seedlings Outperform Bareroot Seedlings On Harsh Sites In Southern Utah, United States Department Of Agriculture, Forest Service
Forestry
Reforestation of ponderosa pine (Pinus ponderosa Dougl. ex Laws.) on the lower elevations of the Dixie National Forest in southern Utah has traditionally been challenging. Replanting has often been necessary, costly, and not always successful. Although this problem is not unique, the low levels of available soil moisture during the spring planting season are probably as critical in the Dixie as anywhere in the Intermountain Region. Until this study was initiated, only bareroot seedlings had been planted.

Parks and Reserves
To ensure maximum coordination of message delivery, personal service efforts should be orchestrated as a result of annual (winter season) planning sessions involving TW Services, Bryce/Zion Trail Rides, and park personnel. Such planning should coordinate general summer season schedules, brainstorm new program ideas and service proposals, and establish procedures for monitoring and evaluation. This is also an opportunity to identify high priority messages regarding resources, events, new services, and park management pertinent in the coming season; in this manner, emphases for seasonal training are established.

Fisheries Report No 76 - The Australian Herring Fishery In Western Australia, 1973 - 1985, Michael H. Walker, Diane P. Clarke
Fisheries Research Reports
The Australian herring (Arripis georgianus) ts a pelagic, largely marine, species which is relatively abundant in the south western waters of Western Australia. It is a close relative of the Australian salmon with a similar life history and habits which includes migrating for the purpose of spawning. The Australian herring is keenly sought both as a food fish and for bait. This report documents the fishery for this species as it has developed during the period 1973 to 1985.
Fisheries Report No 75 - The Commercial Shark Fishery In Temperate Waters Of Western Australia, D. I. Heald
Fisheries Report No 75 - The Commercial Shark Fishery In Temperate Waters Of Western Australia, D. I. Heald
Fisheries Research Reports
The Western Australian-based mixed gear fishery for edible shark generally operates from Geraldton to Esperance in waters shallower than 10 fm to a maximum depth of 100 fm. In 1983/84, the total catch was 1262 tonnes live weight. The total shark catch was taken by 158 gillnet boats, 45 longline boats and 152 handline boats. However, nearly two thirds (62%) of these boats caught 1 tonne or less in 1983/84 and were assumed to rely more heavily on other target fisheries than shark.
Of the 20 or so species of shark caught in W.A., 3 species together comprise two thirds …

Fisheries Report No 77 - The Western Rock Lobster Fishery 1983 - 1984, R. S. Brown, E. H. Barker
Fisheries Research Reports
The fishery for the western rock lobster Panulirus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. Western Australia produced 10,576 tonnes in 1983/84, out of a total Australian rock lobster catch, with the exception of Queensland, of 15,777 tonnes. The fishery is governed by a complex set of regulations which are designed to limit the total fishing effort to acceptable levels and to enforce a legal minimum size (Bowen 1971, Hancock 1981). Thus, it is important to monitor the state of the fishery constantly both to ensure that the …

Fisheries Report No 78 - A Re-Examination Of The Methods Used For Handling Undersize Western Rock Lobsters, R. S. Brown, C J. Dibden
Fisheries Research Reports
The fishery for the western rock lobster, Panulirus cygnus (George) is the most important single species fishery in Australia, and one of the major rock lobster fisheries of the world, with catches over the last ten years (1973 to 1983) averaging approximately 9.8 million kg annually.
The continuing success of the fishery can be attributed mainly to effective management, which involves a complex system of regulations, the majority of which were introduced in 1963 and which are constantly being revised to accommodate changes in the fishery. One important piece of legislation, effective from 17 December 1965, was the introduction of …

Nitrogen Mineralization And Denitrification In Lake Michigan Sediment, Wayne S. Garder, Thomas F. Nalepa, John M. Malczyk
United States Department of Commerce: Staff Publications
Organic nitrogen mineralization mechanisms, fluxes, and fates in Lake Michigan sediments were examined by measuring accumulation rates of inorganic nitrogen in laboratory microcosms. Neither ammonium nor nitrate increased substantially in flow-cell or slurry microcosms of offshore, silty sediments. In experiments with gastight chambers containing "intact" offshore, silty sediment cores (sampled at 45- and 100-m water depths), the total fluxes of nitrogen (NH4+, N03-, and N2) across the sediment-water interface ranged from 14 to 51 µg-atoms N m-2 h-1. Nitrogen gas accounted for 93-98% of the total inorganic nitrogen flux from the …

Marine & Environmental Sciences Faculty Articles
A new Caribbean species, Chevalia carpenteri is described; heretofore only one species of the genus was known, but we have examined material that suggests morphs may represent distinct species or subspecies. We report C. mexicana and extend its range from the northern Gulf of Mexico to Belize. Our new species differs from the world complex of C. aviculae morphs in the ovate article 2 of pereopods 5-7 and the posteriorly flat epimera with large notches.

Determination Of Dissociation Energies And Thermal Functions Of Hydrogen‐Bond Formation Using High Resolution Ftir Spectroscopy, B. A. Wofford, M. E. Eliades, Shannon Lieb, J. W. Bevan
Scholarship and Professional Work - LAS
A technique which employs high resolution Fourier transform infrared spectroscopy is demonstrated for evaluation of hydrogen bonddissociation energiesD 0 and D e . Results for HCN‐‐HF give a D 0=20.77(22) and D e =28.77(45) kJ/mol which are compared with previously determined values obtained from microwave absolute intensity measurements and a b i n i t i o molecular orbital calculations. Rovibrational band information available for HCN‐‐HF also permits evaluation of thermal functions of dimer formation in kJ/mol: ΔU ○ 298.2 =20.1(2), ΔH ○ 298.2 =22.6(2), ΔG ○ 298.2 =59.4(2), ΔS ○ 298.2 =−0.1235.

Scholarship and Professional Work - LAS
Observation of the 2ν1 overtone band in the hydrogen‐bonded complex HCN‐‐‐HF permits evaluation of the anharmonicity constant X 1 1=−116.9(1) cm− 1 and determination of the anharmonicity corrected fundamental frequency ω1. This information, and available data from previous rovibrational analyses in the common and perdeuterated isotopic species of HCN‐‐‐HF, offer an opportunity for calculation of an approximate stretching harmonic force field. With the assumptions f 1 2=f 2 4=0.0, the remaining force constants (in mdyn/Å) are evaluated as: f 1 1=8.600(20), f 2 2=6.228(9), f 3 3=19.115(40), f 4 …
