Water Quality Trends In The Las Vegas Wash Wetlands, F. A. Morris, L. J. Paulson

Publications (WR)

The Las Vegas Wash is a wetlands ecosystem that acts to buffer the effects of wastewater discharges on the receiving waters of Lake Mead. The wash is the terminus for the 4,144 km2 Las Vegas Valley drainage basin, emptying into Las Vegas Bay of Lake Mead (Colorado River). It is in the northern Mojave desert, which receives an average of only 10 cm of rainfall annually. The Las Vegas Wash is technically an artificial wetland supported almost entirely by the perennial flows from sewage treatment plants. These flows contribute an average of 3-7 t of nutrients (nitrogen and phosphorus) and …

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …

Environmental Correlates Of Hermatypic Coral (Montastrea Annularis) Growth On The East Flower Gardens Bank, Northwest Gulf Of Mexico, Richard E. Dodge, Judith C. Lang

Marine & Environmental Sciences Faculty Articles

Time series of annual linear growth increments from 12 Montastrea annularis (E. and S.) collected at the East Flower Gardens Bank reef in the northwestern Gulf of Mexico have a common pattern. This is best expressed in an index master chronology (average by year of the annual percentage deviations from the mean of each coral.)

Comparisons with time series of environmental data indicate that coral extension rates vary positively with seasonal (February through May - 4 months) surface water temperature and negatively with annual discharge of the Atchafalaya River. We propose that secular variations of water temperature and other parameters …

Curidia Debrogania, A New Genus And Species Of Amphipod (Crustacea: Ochlesidae) From The Barrier Reefs Of Belize, Central America, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

The family Ochlesidae is amended to include the new genus Curidia, which differs from all other members by possessing maxiIIipedal palps. Curidia debrogania is described and compared to other genera and species within the family Ochlesidae.

Curidia debrogania is plesiomorphic by possession of maxillipedal palps, suggesting this member of the small, cryptic family might have originated in the tropical Western Atlantic. Distribution records and ecological notes are included.

Image Analysis Of Morphological Changes In Wiener Batters During Chopping And Cooking, A. G. Kempton, S. Trupp

Food Structure

Histological changes in wiener batters during chopping and cooking have often been illustrated with "representative" fields . The practice of selecting representative fields ignores variation and leads to word descriptions that cannot be correlated with numerical scores for functional or sensory tests . If wieners are regarded as a multi-component system, objectivity can be achieved by selecting many fields for each sample according to a rigid sampling plan. Image analysis quantified parameters of both the fat and protein components . The reduction in size of fat globules during chopping of a commercial formulation, for example, was a function of area …

The Foraging Behavior Of Lacewing Larvae On Vertical Rods, Alan B. Bond

Alan Bond Publications

The foraging behavior of lacewing larvae (Chrysopa carnea Stephens, Chrysopidae, Neuroptera) on vertical lucite rods was observed under a variety of experimental conditions to investigate the decision processes responsible for the distribution of foraging effort. Food deprivation increased the duration of searching on all parts of the rod, whereas contact with prey at the rod tip induced only a local enhancement of searching activity. Searching at the rod tip did not decline with repeated trials on the same rod, but the duration of searching on the rest of the rod was reduced, evidently reflecting recognition and avoidance of previously-searched …

Limiting Swine Stress With Evaporative Cooling In The Southeast, Robert L. Fehr, K. T. Priddy, Samuel G. Mcneill, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

Three-hourly weather data for 7 locations in the Southeast and Central United States were used to evaluate the feasibility of evaporative cooling for reducing swine stress. Stress was defined as a relationship between dry and wet bulb temperatures which exceeded a stress index of 85. This analysis indicates that properly installed evaporative coolers could reduce the number of hours that stress would occur in swine facilities from 89.6 to 96.4% depending on location.

Growth And Activity Of Juvenile Mosquitofish: Temperature And Ration Effects, Wayne A. Wurtsbaugh, J. Cech

Watershed Sciences Faculty Publications

The effects of constant temperatures (10, 15, 20, 25, 30, and 35 C) and ration size on the growth rates and activity of juvenile mosquitofish Gambusia affinis (mean wet weight, about 20 mg) were measured in laboratory experiments. On ad libitum rations of Tubifex spp. worms, food-consumption rates of mosquitofish were very high, ranging from 7% dry body weight/day at 10 C to 83%/day at 35 C. Growth increased from 0% dry body weight/day at 10 C to 21%/day at 30 C and declined slightly at 35 C. Gross efficiencies (100 growth/food consumption) increased from 0 at 10 C to …

Pasture Research Programme For The Medium Rainfall Zone Of Wa, P. Dixon

Experimental Summaries - Plant Research

Pasture Research Programme for the Medium Rainfall Zone of W.A. - Species Selection and Management Related in Particular to the Ryegrass Toxicity Problem Since the early 1970's much of the ryegrass based pastures in the Pallinup region have been affected by Annual Ryegrass Toxicity (ARGT). Control of ryegrass by herbicides invariably leads to a reduction in the stock carrying capacity of the pasture since currently available legume species fail to grow or persist. This tendency is particularly evident on the hard setting loam soils of neutral to alkaline reaction. The aim of this project is to find alternative pasture species …
