Corn And Soybean Yield Response To Crop Residue Management Under No-Tillage Production Systems, Wallace Wilhelm, J. W. Doran, James F. Power Jan 1986

Corn And Soybean Yield Response To Crop Residue Management Under No-Tillage Production Systems, Wallace Wilhelm, J. W. Doran, James F. Power

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Crop residues (stover) have many potential uses by society: food, feed, shelter, fuel, and soil amendment. Use of residues for purposes other than as a soil amendment may have serious negative consequences on crop productivity. This study was conducted to investigate the yield response of continuous corn (Zea mays L.) and continuous soybean [Glycine max (L.) Merr.] to removal or addition of crop residues under no-tillage management. The study was conducted near Lincoln, NE, on a Crete-Butler silty clay loam (fine, montmorillonitic, mesic Pachic Arguistoll-Abruptic Argiaquoll) with 1 to 2% slope. Crop residue was collected and weighed immediately …

Founders And Presidents Of The Nebraska Academy Of Sciences, 1880-1986, C. Bertrand Schultz

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Nebraska Academy of Sciences is the oldest interdisciplinary scientific organization in Nebraska and one of the oldest and most successful state academies in the United States. It was founded in Omaha on January 30, 1880, and there were seventy-five Charter Members from eighteen communities.

The Union Pacific Railroad officials and employees provided much of the impetus for the establishment of an Academy of Sciences in Nebraska by providing office space and meeting rooms near the Union Pacific headquarters. Railroad passes were issued to all science teachers, professional scientists, and interested citizens to attend monthly meetings. Five of the officers …

Changes In Feeding And Crawling Rates Of Hydrobia Truncata (Prosobranchia: Hydrobiidae) In Response To Sedimentary Chlorophyll-A And Recently Egested Sediment, Valery E. Forbes, Glenn R. Lopez Jan 1986

Changes In Feeding And Crawling Rates Of Hydrobia Truncata (Prosobranchia: Hydrobiidae) In Response To Sedimentary Chlorophyll-A And Recently Egested Sediment, Valery E. Forbes, Glenn R. Lopez

Valery Forbes Publications

Experiments combining fluorescent particle tracer techniques with time-lapse video recording demonstrated that the gastropod Hydrobia truncata decreases crawling rate on patches rich in chlorophyll-a, while maintaining a constant feeding rate as sedimentary chlorophyll-a content varies. In contrast, H. truncata decreases feeding rate but does not change crawling rate upon encounter with patches of recently egested sediment. Depression of feeding rate is less pronounced if the egested material is enriched in chlorophyll-a. For deposit feeders inhabiting highly reworked sediments, the majority of available material may consist of sediment that has been recently egested. For an animal that responds negatively to recently …

Incidence And Significance Of Giardia Lamblia (Lambl ) In Texas Beaver Populations, Robert Beach, William F. Mcculloch Dec 1985

Incidence And Significance Of Giardia Lamblia (Lambl ) In Texas Beaver Populations, Robert Beach, William F. Mcculloch

Great Plains Wildlife Damage Control Workshop Proceedings

The Giardia lamblia (Lambl) protozoan is not a recently discovered parasite. It was. in fact, one of the first organisms viewed and described by Antony van Leeuwenhoek (1681) as he designed the first usable microscope. Leeuwenhoek found this organism in a sample of his own diarrhetic stool and thus he constitutes the first confirmed case of human giardiasis. His finding represents proof of glardiasis’ close association with man for many years. Leeuwenhoek’s discovery of the giardial trophozoite was not elaborated on for some 178 years, however, as it was not until 1859 that Wilhelm D. Lambl systematically described the organism …

Alligator Nuisance Control Program In Texas: Problem And Process, Lee Ann Johnson, David S. Lobpries, Bruce G. Thompson

Great Plains Wildlife Damage Control Workshop Proceedings

Following protection of the American alligator (Alligator mississippiensis) in Texas beginning in 1969, alligator numbers have increased rapidly (Patter 1981). Such population increases led to the federal reclassification of the species from Endangered to Threatened--Similarity of Appearance in 1983 in Texas (Bowman 1983). Similarity of appearance classification acknowledges the biological security of the Texas alligator population and the need for specific harvest controls to ensure that the conservation of similar appearing species is not compromised. As alligator populations recovered, nuisance complaints directed to the Texas Parks and Wildlife Department (T'PWD) accelerated as well. Complaints now number several hundred annually and …

The Extirpation And Re-Establishment Of Coyotes In The Edwards Plateau Of Texas, Gary Nunley Dec 1985

The Extirpation And Re-Establishment Of Coyotes In The Edwards Plateau Of Texas, Gary Nunley

Great Plains Wildlife Damage Control Workshop Proceedings

In the early 1900's organized predator control was initiated to remove coyotes and wolves from the sheep and goat producing areas of Texas. Operations were begun in the Edwards Plateau, the largest area of sheep concentration. By the 1920's, many of the inner Edwards Plateau counties were considered to be practically free of coyotes (Canis latrans) and wolves (Canis lupus, Canis rufus). The 1950's found coyotes and wolves extirpated from most of the Edwards Plateau. After a coyote population erruption in the late 1950's, coyotes began to re-establish themselves on the periphery of the Plateau. This encroachment process continued throughout …

Wildlife Damage In Australia: Constructive Contrasts With The United States, Terrell P. Salmon Dec 1985

Wildlife Damage In Australia: Constructive Contrasts With The United States, Terrell P. Salmon

Great Plains Wildlife Damage Control Workshop Proceedings

There are numerous wildlife damage problems in Australia. The major pests include rabbits (Oryctolagus cuniculus), foxes (Vulpes vulpes), starlings (Sturnus vulgaris), feral cats (Felis catus), donkeys (Equus asinus), goats (Capra hircus), buffalo (Bubalus trutralis), pigs (Sus scrofa), all of which have been introduced. The dingo (Canis familiaris dingo), classified as being a native species by most people, is the primary native animal causing problems, although others, such as kangaroos and several native bird species, are pests in some areas. The Australians spend considerable amounts of money on wildlife damage control research. The people of Western Australia take a regulatory approach …


Livestock Guarding Dogs Protect Domestic Sheep From Coyote Predation In Kansas, William F. Andelt Dec 1985

Livestock Guarding Dogs Protect Domestic Sheep From Coyote Predation In Kansas, William F. Andelt

Great Plains Wildlife Damage Control Workshop Proceedings

Sheep (Ovis aries) producers were surveyed in Kansas to determine the efficacy of livestock guarding dogs (Canis familiaris) for protecting sheep from coyote (Canis latrans) predation. The majority of producers rated their guard dogs' predator control performance as good or excellent, indicating. that the dogs reduced their reliance on other control methods and substantially reduced monetary losses.

Coyote Vulnerability To Several Management Techniques, Frederik F. Knowlton, Lamer A. Windberg, Cram E. Wahlgren

Great Plains Wildlife Damage Control Workshop Proceedings

We appreciate this opportunity to present a brief synopsis of a complex field study recently completed near Laredo, Texas. It provides a preliminary assessment of differences in coyote vulnerability to several management tools At this point, our analyses are incomplete and interpretations are tentative, at best nonetheless, the data provide some insights and a basis for speculations and questions about coyote behavior, population processes, and the logistics of coyote population reduction. This research was sponsored by the U.S. Fish and Wildlife Service (through the Predator Ecology and Behavior Project) and the Caesar Kleberg Wildlife Research Institute, with generous assistance from …


Furbearer Management And The Steel Foothold Trap, Samuel B. Linhart Dec 1985

Furbearer Management And The Steel Foothold Trap, Samuel B. Linhart

Great Plains Wildlife Damage Control Workshop Proceedings

The trapping of furbearers, particularly with steel foothold traps, has become more and more controversial. The controversy is significant because the steel trap is considered the most versatile of the various methods available for capturing furbearers (Payne 1980). Whether traps are used to reduce livestock losses by predators or to harvest furs, the controversy has gained the attention and interest of various social factions, each with differing beliefs, attitudes, and philosophies.

The Use Of Population Reduction As A Technique To Combat Rabies In Alberta, Canada, Richard C. Rosatte Dec 1985

The Use Of Population Reduction As A Technique To Combat Rabies In Alberta, Canada, Richard C. Rosatte

Great Plains Wildlife Damage Control Workshop Proceedings

Control of rabies by reducing the density of potential vectors has been a controversial matter. Only 2 outbreaks of rabies in Europe are likely to have been completely eradicated by control, 1 in Dijon, France, in 1923, and the other in Corsica in 1943 (MacDonald 1980). Schnurrenberger et aL (1964) apparently controlled an outbreak of rabies in striped skunks (Mephitis mephitis) in Ohio by gassing dens and through the use of poison. An invasion of red fox (Vulpes vulpesl rabies in southern Jutland from Demark was initially halted by a gassing and poisoning campaign. However, in Great Britian, despite the …
