A Report On Black-Tailed Prairie Dogs In Nebraska-- Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence, Nancy S. Foster
A Report On Black-Tailed Prairie Dogs In Nebraska-- Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence, Nancy S. Foster
School of Natural Resources: Dissertations, Theses, and Student Research
I examined the effects of a visual barrier fence, which had a see-through visibility of 600/0, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs from June through August 1990 in central Nebraska. I also examined changes in their home ranges and use of an area in response to this fence. Prairie dogs prefer an open view of their surroundings. Therefore, I expected animals near a visual barrier to spend more time in vigilance and aggression, and less time foraging. Adult female prairie dogs exposed to the visual barrier devoted more time to foraging and less …

The Pacific/ North American Teleconnection Pattern And United States Climate. Part I: Regional Temperature And Precipitation Associations, Daniel J. Leathers, Brent Yarnal, Michael A. Palecki
School of Natural Resources: Faculty Publications
The Pacific/ North American (PNA) teleconnection index, a measure of the strength and phase of the PNA teleconnection pattern, is related to the variations of the surface climate of the United States from 1947 through 1982 for the autumn, winter, and spring months when the PNA is a main mode of Northern Hemisphere mid-tropospheric variability. The results demonstrate that the PNA index is highly correlated with both regional temperature and precipitation. The strongest, most extensive correlations between the index and temperature are observed in winter, but large areas of the country show important associations during the spring and autumn as …

Alternative Usages Of Wetlands Other Than Conventional Farming In Iowa, Kansas, Missouri, And Nebraska, Ellen Leventhal, Hubert H. Humphrey
United States Environmental Protection Agency: Staff Publications
Conversion of wetlands in Iowa, Kansas, Missouri, and Nebraska into agricultural dry lands in the past several decades has occurred as a means to obtain profit from what landowners would otherwise consider unprofitable land. This activity has resulted in substantial losses of wetlands valued for their unique ability to mitigate flood and storm damage, control erosion, discharge and recharge groundwater, improve water quality, and support a wide diversity of fish, wildlife, and vegetation.
Utilizing fish, wildlife, and vegetation from wetlands for profit is a way for wetland owners to recognize the value their wetlands add to their property. Landowners then …

Disappearance And Recoverability Of Songbird Carcasses In Fruit Orchards, Mark E. Tobin, Richard A. Dolbeer
Disappearance And Recoverability Of Songbird Carcasses In Fruit Orchards, Mark E. Tobin, Richard A. Dolbeer
USDA Wildlife Services: Staff Publications
Songbird mortality due to agricultural pesticides is often assessed by searching treated areas for carcasses. However, carcass removal by scavengers and the failure of searchers to find carcasses that are present may bias mortality estimates. We conducted two studies in 1987 and 1988 in New York to evaluate such biases at the time of fruit maturation in cherry and apple orchards. In the first study, mean survival times for carcasses were 8.2 d in cherry and 10.4 d in apple orchards. In the second study, searchers located an average of 75% of carcasses placed in orchards. Our results suggest that …

In response to the need climate services at the local, state, and regional levels, a national network of regional climate centers has developed. This provides the background to this development, and outlines the functions of the centers and identifies their benefits and beneficiaries. The centers are a source of climate expertise and maintain multifaceted interfaces with the public and private sectors. Each center a) performs services, including the management of the basic data for its region and the delivery of specialized products; b) conducts applied climate studies, including the monitoring of anomalous conditions and the promotin of regional research; and …
Alternatives To Fisher's "Exact Test" For Analyzing 2 X 2 Tables With Small Cell Sizes, Richard M. Engeman
Alternatives To Fisher's "Exact Test" For Analyzing 2 X 2 Tables With Small Cell Sizes, Richard M. Engeman
USDA Wildlife Services: Staff Publications
Rice (1988a) presents an interesting test for analyzing 2 X 2 contingency tables in the smaller sample size situations. His motivation was to provide an alternative to Fisher's "exact test" and his rationale was based on the application of a prior distribution to the probability of a success, 0, under the null hypothesis. We would like to briefly comment on these aspects of his paper and also discuss another alternative that was proposed a number of years ago.
Warfarin Resistance Of Rattus Tiomanicus In Oil Palms In Malaysia And The Associated Increase Of Rattus Diardii, B.J. Wood, G.F. Chung
Warfarin Resistance Of Rattus Tiomanicus In Oil Palms In Malaysia And The Associated Increase Of Rattus Diardii, B.J. Wood, G.F. Chung
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
Rattus tiomanicus is a serious pest of oil palm plantations in Peninsular Malaysia, feeding on the ripening fruit. R. diardii is a rat of human habitations and has been only an occasional field species, presumably because it cannot compete with better adapted species. A widely used control for R. tiomanicus of proven effectiveness uses maize-based baits containing warfarin at 0.05% in 2 cm3 (14.5 g) wax-bound cubes. These are applied in campaigns at one per palm, replaced on 4 daily rounds, until acceptance has declined to 20%. This "standard method" is applied at about 6-month intervals, and rat populations remain …

Politics And Economics Of Maintaining Pesticide Registrations, Kathleen A. Fagerstone, Roger W. Bullard, Craig A. Ramey
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was amended in 1988 to require the reregistration of all pesticides registered before 1984 within 9 years. The FIFRA 88 required that all pesticide active ingredients must meet current registration standards, suspended the previous fee structure, and imposed a one-time registration fee and annual maintenance fees. New data generated because of FIFRA 88 must conform to EPA's Good Laboratory Practice Standards and animal studies must follow guidelines of the Animal Welfare Act. FIFRA 88 has significantly increased data requirements, data costs, and other pesticide registration and reregistration costs for most pesticides. The …
The Effect Of Seed Coat Colour And Depth Of Planting On Bushfowl Damage To Planted Maize Seeds, Modupe Akande, A.O. Obajimi
The Effect Of Seed Coat Colour And Depth Of Planting On Bushfowl Damage To Planted Maize Seeds, Modupe Akande, A.O. Obajimi
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
The bushfowl (Francolinus bicalcaratus bicalcaratus L.) is a major avian pest on planted maize seeds. Maize seeds colored green and normal white seeds were planted at different depths of 2.5 cm, 5.0 cm, 7.5 cm, 10.0 cm, 12.5 cm, and 15.0 cm in three different trials between 1987 and 1988. The effect of planting depth was highly significant. Damage occurring to seeds planted at a depth of 2.5 cm was significantly higher than all the other depths, even though there was not significant damage among the other depths.
Closing Remarks For The Fourteenth Vertebrate Pest Conference, John E. Borrecco
Closing Remarks For The Fourteenth Vertebrate Pest Conference, John E. Borrecco
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
This concludes the 14th Vertebrate Pest Conference. Before my closing remarks, let us acknowledge the excellent job done by our session chairpersons and speakers. For your information, we had 345 people registered at the conference, representing 37 states and 11 other countries. I first attended the Vertebrate Pest Conference some 14 years ago at the 7th Conference. At that time I was impressed with the breadth of subjects presented, the international scope, the professional exchange of information, and the opportunity to meet noted experts in vertebrate pest control. Since that meeting, I have always looked forward to the next conference …
Native Heteromyid Rodents As Pests Of Commercial Jojoba, Rex O. Baker
Native Heteromyid Rodents As Pests Of Commercial Jojoba, Rex O. Baker
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
After crop losses of 5 to 60% were noted on two 500-acre Jojoba (Simmondsia chinensis) plantings in a desert area of southern California, a study was conducted to identify the animals responsible. Various population census and pestidentification techniques were utilized. Four native rodents of the Heteromyid family, not previously known to be pests of Jojoba, were found to be present in sufficiently high numbers to cause severe economic crop loss. The Bailey's pocket mouse (Perognathus baileyi) was the only rodent previously known to survive on Jojoba beans as a food source. A natural chemical, cyanogenic glucoside, …
Effect Of Artificial Perches And Nests In Attracting Raptors To Orchards, Leonard R. Askham
Effect Of Artificial Perches And Nests In Attracting Raptors To Orchards, Leonard R. Askham
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
Artificial perches and nest boxes were placed in three Pacific Northwest orchards to assess their effectiveness in attracting birds of prey to reduce vole populations. The data indicated that birds could be attracted under some conditions, but vole populations were not significantly affected. Additional factors such as vegetative biomass and human activity may limit their usefulness in reducing rodent populations under intensive agricultural conditions.
Animal Damage Problems And Control Activities On National Forest System Lands, John E. Borrecco, Hugh C. Black
Animal Damage Problems And Control Activities On National Forest System Lands, John E. Borrecco, Hugh C. Black
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
A questionnaire survey of the National Forests in 1988 indicated that animal damage control (ADC) was conducted on 208,000 acres of reforestation and older stands, nearly all in the West, at a cost of about $9 million. Sixty-two percent of the total acreage treated, or 128,600 acres, and 49 percent of the ADC costs, or $4.3 million, was in the Pacific Northwest Region (Oregon and Washington). Most of the forests in all regions of the Forest Service, except Alaska, rated animal damage to reforestation and older stands as very important or moderately important. One-third of the forests rated damage as …
Lamb Predation In Patagonian Ranches, J. Bellati, J. Von Thungen
Lamb Predation In Patagonian Ranches, J. Bellati, J. Von Thungen
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
Lamb predation in Patagonia, Argentina, is considered by ranchers as the cause of one of their greatest losses and limits sheep production. Patagonian red fox (Dusicyon culpaeus) is the main predator and the magnitude of the problem reflects its distribution and abundance. Since 1979, the Bariloche Experimental Station of the Instituto Nacional de Technologia Agropecuaria (INTA) has performed 8 studies, totaling 1,717 lamb necropsies, with the purpose of determining the relative importance of predation and other causes of lamb mortality. This paper analyzes the causes of lamb mortality, with special reference to red fox and carnivorous bird predation. …

Bromethalin Toxicosis-Evaluation Of Aminophylline Treatment And An Epidemiologic Assessment, David C. Dorman, Alan J. Parker, William B. Buck
Proceedings of the Fourteenth Vertebrate Pest Conference 1990
The reported LD50 for technical grade bromethalin ranges from 1.8 mg/kg in the cat, 4.7 mg/kg in the dog, and 13 mg/kg in rabbits, and up to >1000 mg/kg in guinea pigs (VanLier and Ottosen 1981, VanLier and Cherry 1988). Mitochondrial electron transport studies using purified rat brain and liver mitochondria have been performed, and have established that bromethalin is an effective uncoupler of oxidative phosphorylation (VanLier and Ottosen 1981, Cherry et al. 1982, VanLier and Cherry 1988). Mitochondrial oxidative phosphorylation is the major mechanism for production of ATP in the brain. Uncoupling of this reaction in bromethalin-poisoned animals …
