Bulletin No 4168 - Plants In Australia Which When Eaten Produce Photosensitization In Livestock, T E H Aplin Jan 1990

Bulletin No 4168 - Plants In Australia Which When Eaten Produce Photosensitization In Livestock, T E H Aplin

Bulletins 4000 -

Photosensitization is the term used to describe inflammation of the skin (usually unpigmented) caused by photodynamic compounds, circulating in blood stream, becoming bound to dermal cells and fluorescing when the animal is exposed to ultraviolet light (290-400 nm).

Photosensitization usually occurs when an animal eats certain plants that contain photodynamic compounds. These compounds can be deposited unchanged in the skin after ingestion, the normal liver being incapable of excreting the native fluorescent compound. This is termed type 1 photosensitization and the compounds involved are naphthodianthrone derivatives. Photodynamic compounds can also be produced through aberrant metabolism by the liver due to …

Competition Between Dipodomys And Perognathus In The Anza Borrego Desert State Park, Jodi Dorsey Jan 1990

Competition Between Dipodomys And Perognathus In The Anza Borrego Desert State Park, Jodi Dorsey

Whittier Scholars Program

The purpose of this experiment was to discover if competition for food and space existed between kangaroo rats and pocket mice. On three separate occasions, over eighty traps were set in a region of the Sonoran Desert near Anza Borrego Desert State Park. A total of seventy-eight kangaroo rats were caught, but not a single pocket mouse. There is no conclusion drawn about whether or not competition occurs between the two species. The project explains how each species has adapted to the harsh desert environment, and outlines suggested changes for a future experiment.


Spacing Water Points In The Southern Pastoral Areas Of Western Australia, Don Burnside, Adrian Williams, Peter Curry Jan 1990

Spacing Water Points In The Southern Pastoral Areas Of Western Australia, Don Burnside, Adrian Williams, Peter Curry

Bulletins 4000 -

An inadequate distribution of watering points in our pastoral lands, particularly in the saltbush/bluebush pasture, has caused localisized land degradation close to waters and reduced animal productivity (particularly in stressful times). From experimentation and observation, some generalised recommendations for water supply distribution in pastoral areas can be made.


Effects Of Ambient Lake Mohave Temperatures On Development, Oxygen Consumption, And Hatching Success Of The Razorback Sucker, Michael A. Bozek, Larry J. Paulson, Gene R. Wilde Jan 1990

Effects Of Ambient Lake Mohave Temperatures On Development, Oxygen Consumption, And Hatching Success Of The Razorback Sucker, Michael A. Bozek, Larry J. Paulson, Gene R. Wilde

Publications (WR)

Spawning of razorback suckers, Xyrauchen texanus, in Lake Mohave occurred from 10-22° C and larvae were collected at water temperatures from 10-15° C in 1982 and 1983. In the laboratory, hatching success was similar from 12-20° C, but reduced hatching success was found at 10° C while none hatched at 8°C. Development rate and oxygen consumption were positively related to incubation temperature. Direct effects of ambient Lake Mohave water temperatures on hatching success of razorback sucker embryos are considered minimal. Historical spawning temperatures for the species are hypothesized based upon successful incubation temperatures and comparison to the white sucker, …


Aqueous Absorption Of Nox Induced By Sodium Chlorite Oxidation, Chen-Lu Yang Dec 1989

Aqueous Absorption Of Nox Induced By Sodium Chlorite Oxidation, Chen-Lu Yang

Theses

Aqueous scrubbing in alkaline media for the removal of nitrogen oxides (NOx) from flue gases using NaClO2 as an oxidant is being investigated in the Chemical Engineering Department of New Jersey Institute of Technology. This thesis presents the findings of an experimental program that was conducted to estimate the capability of NaClO2 aqueous solution to oxidize insoluble NO to soluble NO2 in order to increase its solubility and thus prevent NOx emission from entering the atmosphere from flue gases emitted by municipal incinerators or power plants.

The key findings of this program are:

Species Richness Gradients Of Oak Forest Plants Along The Missouri River In Nebraska And Iowa, Steven B. Rolfsmeier Dec 1989

Species Richness Gradients Of Oak Forest Plants Along The Missouri River In Nebraska And Iowa, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The upland deciduous forests of the Missouri River valley contain many plants typical of forests to the east of this area, which are assumed to have migrated northward and westward along the river in postglacial times. Previous workers have reported a gradient of decreasing species richness upstream among woody species, which is suggested to be the result of climatic gradients and differential dispersal capabilities of the immigrant species. Floristic work on all vascular species in eight woodland sites along the Nebraska-Iowa border quantifies the presence of similar gradients for herbaceous species, but of differing degrees. These studies also reveal the …


Introduction And Enhancement Of Vegetative Cover At Lake Mead, Jennifer S. Haley, Lisa K. Croft, Suzanne E. Leavitt, Larry J. Paulson Dec 1989

Introduction And Enhancement Of Vegetative Cover At Lake Mead, Jennifer S. Haley, Lisa K. Croft, Suzanne E. Leavitt, Larry J. Paulson

Publications (WR)

Studies done by the Nevada Department of Wildlife (NDOW) and the Arizona Fish and Game between 1978 and 1981 indicate that inadequate cover may be limiting the production and survival of largemouth bass at the Lake Mead National Recreation Area (LMNRA). As a result of these studies, NDOW initiated a contract in 1986 with the Lake Mead Research Center (LMRC) to investigate means of improving habitat for game fish by introducing natural and/or artificial cover. During Phase I (1986-1987) of this contract, the shoreline of Lake Mead was surveyed for aquatic and terrestrial plant growth. Also during this time, submerged …


Frequency-Dependent Seed Dispersal By Ants Of Two Deciduous Forest Herbs, Brent H. Smith, Catherine E. De Rivera, Cara Lin Bridgman, John J. Woid Dec 1989

Frequency-Dependent Seed Dispersal By Ants Of Two Deciduous Forest Herbs, Brent H. Smith, Catherine E. De Rivera, Cara Lin Bridgman, John J. Woid

Environmental Science and Management Faculty Publications and Presentations

Two co—occurring deciduous forest myrmecochores, Asarum canadense and Jeffersonia diphylla, release their seeds at approximately the same time, and therefore potentially compete for ants as dispersers. Within a single woodlot, we placed seeds of both species inside a dense Jeffersonia population away from Asarum plants, inside a dense Asarum population away from Jeffersonia plants, and in a site where plants of neither species occurred. No preference was exhibited by ants where natural populations were absent. Preference at the other two sites was frequency dependent: ants preferred seeds of the introduced species. Species preferred by ants have higher seed and …

Herring Gulls, Larus Argentatus, Nesting On Sandusky Bay, Lake Erie, 1989, Richard A. Dolbeer, P.P. Woronecki, T. W. Seamans, B. N. Buckingham, E. C. Cleary

United States Department of Agriculture Wildlife Services: Staff Publications

One of the largest herring gull (Larus argentatus} nesting populations on the Great Lakes is located in an urban setting on Sandusky Bay in the Ohio portion of Lake Erie. The survey reported here, carried out in 1989, indicated a population of 4,250 nests. The population has expanded from a focal point on Turning Point Island to coal piles at the Lower Lake Dock Company, rooftops in downtown Sandusky and breakwalls near Cedar Point. Comparison with data from a survey performed in 1976 indicates the population has grown at an average annual rate of 11.9% during the past 13 years. …

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke Oct 1989

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke

Fisheries Research Reports

Traps have been a controversial method of catching pink snapper Chrysophrys auratus (Sparidae) around Shark Bay, Western Australia, since 1959. The history of the issue and the relevant regulations are reviewed; and results of in­vestigations into specific concerns about trap fishing are reported. Concerns of ghost-fishing by lost traps have been largely allayed by underwater TV film of snapper escaping from a standard snapper trap.

A major concern was that traps might physically damage the benthic fauna, e.g. corals. A TV survey showed that while fragile hard corals are abundant in shallower water nearby, the deeper snapper grounds themselves are …

An Investigation Of Animal Damage Associated With Maple Syrup Production, J. Alan May, Dennis Slate Sep 1989

An Investigation Of Animal Damage Associated With Maple Syrup Production, J. Alan May, Dennis Slate

Wildlife Damage Management Conference

An increase in the use of plastic tubing systems to collect sap from sugar maples (Acer saccharum) has allowed syrup producers to boost production in recent years, but not without cost. Rodents gnawing on tubing, spouts, and fittings may cause damage in excess of $300,000 annually in Vermont, the largest maple producing state. Red squirrels (Tamiasciurus hudsonicus), gray squirrels (Sciurus carolinensis), and chipmunks (Tamias striatus) appear to be responsible for the majority of damage. Other species including flying squirrels (Glaucomvs sabrinus), white-footed mice (Peromvscus leucopus), porcupines (Erethizon …


Farmer Attitudes Toward Wild Turkeys In Southwestern Wisconsin, Scott R. Craven Sep 1989

Farmer Attitudes Toward Wild Turkeys In Southwestern Wisconsin, Scott R. Craven

Wildlife Damage Management Conference

The reintroduction of the Wild Turkey (Meleagris gallopavo) represents one of the great success stories for Wisconsin wildlife management. Human settlement, habitat loss, and perhaps disease, combined to eliminate once-common turkeys from Wisconsin by 1900. Periodic attempts to restore a viable turkey population were unsuccessful with the exception of a small flock at Meadow Valley-Necedah in central Wisconsin. However in 1976, the Wisconsin Department of Natural Resources (WDNR) began a new, well conceived cooperative project with the Missouri Department of Conservation. Under the agreement, Missouri received 3 wild Wisconsin ruffed grouse (Bonasa umbellus) in exchange for …


Population Dynamics And Management Of Deer In Wisconsin, Keith R. Mccaffery Sep 1989

Population Dynamics And Management Of Deer In Wisconsin, Keith R. Mccaffery

Wildlife Damage Management Conference

Management of deer in Wisconsin is affected by a combination of biological and environmental factors. In the Northern Forest, winter severity dramatically affects annual survival and recruitment. However, deer density goals here are above "I" carrying capacity. Thus, minor errors in harvest management are in part compensated by herd responses. Deer in the farmland areas of the state are maintained at goals that for the most part are below "I" carrying capacity. Errors in harvest management are magnified in farmland because herd responses are not compensatory. Therefore, the harvest quotas for antlerless deer must be more precise in our farmland …


Black Bear Damage In Virginia, Michael R. Vaughan, Patrick F. Scanlon, Sue Evelyn P. Mersmann, Dennis D. Martin Sep 1989

Black Bear Damage In Virginia, Michael R. Vaughan, Patrick F. Scanlon, Sue Evelyn P. Mersmann, Dennis D. Martin

Wildlife Damage Management Conference

We examined records of black bear damage in Virginia on Shenandoah National Park, (SNP) (1979-1988) and non-Park lands (1973-1988). Mean annual damage was $5,470 on non-Park lands and $1,217 on the Park. Corn and beehives accounted for 79 percent and personal property for 72 percent of the economic loss on non-Park and Park lands respectively. Young males were responsible for most damage on non-Park lands while adults of both sexes caused most damage on SNP. Over 70 percent of bear damage incidents in the state occurred either on the Park or on land immediately adjacent to the Park. Moving bears …


Farmland Habitat Use By Wild Turkeys In Wisconsin, R. G. Wright, R. N. Paisley, J. F. Kubisiak Sep 1989

Farmland Habitat Use By Wild Turkeys In Wisconsin, R. G. Wright, R. N. Paisley, J. F. Kubisiak

Wildlife Damage Management Conference

Habitat use and food habits of wild turkeys (Meleagris gallopavo) were studied during summer 1988-89 in southwestern Wisconsin in order to address growing concerns that turkeys cause considerable crop damage. Intensive telemetric monitoring in 1988 suggested that turkeys used crop fields (corn-alfalfa-oats) at a low rate compared to forest types. Brooded hens used forest habitats less and field habitats more than broodless hens and gobblers. Brooded hens appeared to use forest and crop field habitats less and non-crop fields (pasture and idle) more than expected. Broodless hens and gobblers appeared to use forest types and non-crop fields more …


Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn Sep 1989

Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn

Wildlife Damage Management Conference

During the winters of 1987-88 and 1988-89 a study was conducted to evaluate the potential of DRC-1339 baiting for controlling roosting European Starlings (Sturnus vulgarus) at Tennessee Eastman Company's chemical manufacturing plant in Kingsport, Tennessee. In 1987-88 Starlicide CompleteR (1% DRC-1339 treated poultry pellets diluted 1:9 with untreated poultry pellets) was used in preroosting congregating areas adjacent to the roost. In 1988-89 Starlicide CompleteR and DRC-1339 treated bread were used in bait containers placed in the roosting structure. Although 90 lbs of Starlicide CompleteR was consumed during 1987-88, bait consumption was sporadic and no appreciable change in the …
