Effects Of Taste Stimuli (Quinine And Sucrose) In Pelleted Granulated, And Wax Block Baits On Feeding Preferences Of Northern Pocket Gophers (Thomomys Talpoides), Stephen A. Schumake, Geraldine R. Mccann

Vertebrate Pest Conference Proceedings: 18th (1998)

A two-choice, taste preference study was conducted using 18 northern pocket gophers to evaluate pelleted sorghum, granulated sorghum, and wax block baits containing either 0.01 to 0.05 % quinine or 0.10 to 5.0 % sucrose. Bait consumption was significantly higher across treatments (P≤.001) for granulated sorghum, followed by pelleted sorghum, and wax blocks. Gophers also showed a high frequency of moving the granulated bait in their cheek pouches to be deposited at alternate locations within their cages. Although increasing sucrose concentration did not produce significantly (P ≥.10) enhanced consumption for any of the baits, a trend toward increasing preference with …

The Determination Of The Potential Of Australian Native Plants To Phytoremediate Lead, Desmond Dev Menon

Theses : Honours

Industrial activities and natural occurrences of mineral ores can both result in the presence of high concentrations of heavy metals in the soil. These toxic metals have been shown to adversely affect human health and the environment. Currently, three main technologies are being used to solve this problem of soil contamination. These are incineration, landfill construction and physico-chemical treatments. The economic and environmental costs of each of these technologies tend to outweigh the merits of their application, especially where contaminated areas are small. These techniques do not necessarily remove the heavy metals from the soil, and can also inhibit biological …

Secondly, an in-depth look at energy requirements for all farming types is evaluated. Third, previous studies of the energy requirements in agriculture are examined; this includes both analyzing organic and conventional farming practices. A survey was generated from the information gathered. The survey was conducted via face-to-face interviews. When all the …

Environmental Stress Effects On Vigor, Mortality, And Growth In Northern Hardwood Forests Along A Pollution-Climate Gradient, Neil W. Macdonald, John A. Witter, David R. Reed, Andrew J. Burton, Kurt S. Pregitzer, Hal O. Liechty

Peer Reviewed Publications

Concern exists over the effects of interacting environmental stresses on the ecological integrity of temperate forests. Coincidence of sensitivity to drought, increasing occurrence of defoliation, and elevated pollutant deposition has produced speculation that northern hardwood forests may be susceptible to the increased climatic stresses projected for the Great Lakes region. The objective of our study was to examine relationships among environmental stress factors, vigor, mortality, and growth in northern hardwood forests located along a pollution-climate gradient in the Great Lakes region. Between 1987 and 1993, we quantified climatic variables, pollutant deposition, insect defoliation, and tree vigor and growth at five …

Early Life History Stages Of Gulf Sturgeon In The Suwannee River, Florida, Kenneth J. Sulak, James P. Clugston

United States Geological Survey: Staff Publications

Egg sampling confirmed that Suwannee River Gulf sturgeon Acipenser ozyrinchus desotoi, a subspecies of Atlantic sturgeon A. o. oxyrinchus use the same spawning site at river kilometer (rkm) 215 from the mouth of the river each year. Forty-nine eggs were recorded in 1995, and 368 were recorded in 1996. Spawning began 4-7 d after the March new moon in both years and lasted 10-11 d; in 1996, a second 10-d spawning round began on the April new moon. Developmental synchrony among eggs recovered suggested serval discrete spawning events in both years. Total eggs deposited for three 1996 sampling days …

Pesticide-Related Health Problems And Illness In Farm-Workers In The United Arab Emirates, Mahra Mohammed Mahmood Beshwari

Theses

Arabian Gulf countries, witnessed rapid development in many aspects of life. Although these

developments have improved the quality of life in the UAE, they have drawbacks that generated

health problems and environmental hazards. One of the consequences of rapid development is the

usage of large amounts of pesticides in agricultural production for the sake of increasing the yield of crops. However, the expanded use of these pesticides is known to result in acute respiratory symptoms and changes in body metabolism. To-date, no population-based study has been conducted to investigate the effects of pesticides on plasma amino acids and liver enzyme …

The Detoxification Of Petroleum Contaminated Coastal Plain Sandy Soil Using An Amended Vermicomposting Approach, John Charles Kraemer

Health Services Research Dissertations

This study explores the feasibility of utilizing an amended vermicomposting treatment approach for detoxifying petroleum hydrocarbon contaminated sandy soil. The bench-scale testing of gasoline and diesel contaminated soil using three test soil vessels and one control soil vessel was performed in a laboratory setting for a six week time period. The control soil received no treatment other than distilled water to maintain soil moisture. Treatment 1 consisted of direct application of liquid municipal biologic sludge on a weekly basis. Treatment 2 consisted of the addition of 30 Eisenia foetida earthworms and distilled water. Treatment 3 consisted of direct application of …

Coyote Food Habits At Desoto National Wildlife Refuge, Nebraska, Jeffrey J. Huebschman, Scott E. Hygnstrom, Joseph A. Gubanyi

School of Natural Resources: Faculty Publications

Coyote (Canis latrans) food habits were detennined from 490 scats collected from October 1994 to October 1995 at DeSoto National Wildlife Refuge (DNWR), along the Nebraska/Iowa border. Mammals occurred most frequently, as measured by percent-of-scats (POS) , followed by vegetation, birds, and invertebrates. Mammals also constituted the largest portion of coyote diet, as determined by fresh weight correction factors. Within the mammalian category, white-tailed deer (Odocoileus virginianus) occurred most frequently and constituted the largest portion of diet by fresh weight correction factors. White-tailed deer occurrence and importance in diet peaked in June, which corresponds to the …

Bulletin 4328 - Soil Testing For Vegetable Production On The Coastal Plain, Ian Mcpharlin, Murray Hegney

Bulletins 4000 -

Vegetable growers need to use fertiliser efficiently. Under-fertilising can reduce yield, which results in economic losses. Over-fertilising can reduce yield and contribute to nitrogen and phosphorus pollution of ground and surface waters. Concerns have been expressed that fertilisers applied to horticultural crops contribute to the phosphorus pollution of the rivers and estuaries of the west and south coast of Western Australia.

Soil testing is a technique that can be used by growers to make better fertiliser decisions. When soil tests show high levels of nutrients, growers can reduce fertiliser application for the current crop. This should enable growers to maintain …

Carrion Seeking In Brown Tree Snakes: Importance Of Olfactory And Visual Cues, John A. Shivik, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

We performed field experiments to examine brown tree snake (Boiga irregularis) attraction to carrion. These snakes were attracted to carrion and entered traps baited with dead mice as readily as traps baited with live mice. Using the cues arising from both live and dead prey, we examined the relative importance of visual and chemical cues to brown tree snakes. With carrion lures, chemical cues alone were sufficient for attracting and capturing snakes, but with live prey lures visual cues were required to attract and capture brown tree snakes. Our study presents the first experimental field evidence showing carrion …

Sheep Predation By Coyotes: A Behavioral Analysis, Ray T. Sterner

Great Plains Wildlife Damage Control Workshop Proceedings

This paper presents (1) a brief overview of several concepts important to predator-prey behaviors of coyotes, (2) results of an enclosure study of sheep-attack, -immobilization, and -ingestion responses involving 12 male coyotes (Canis latrans) that were paired with sheep after observing various sheep- predation events by conspecifics, and (3) an analysis of sheep predation based upon operant learning principles. Contrasts between comparative psychological and ethological approaches to the study of animal behavior are described. Results of the enclosure study (0.127-ha) showed that following matched-length trials of observing predation, non-predation, and lone sheep, 3, 2, and 1 coyote(s), respectively, …

Elk Vs. Livestock: Forage Utilization Study In Portions Of The Gila National Forest., Michael Treadaway, V.W. Howard Jr., Chris D. Allison, Jon C. Boren

Great Plains Wildlife Damage Control Workshop Proceedings

In areas where elk (Cervus elephus) and livestock, mainly cattle (Bos taurus), occupy the same rangeland the potential for competition exists, which may adversely effect each species. Competition between these herbivores may occur for herbaceous vegetation in areas with high elk numbers and moderate livestock numbers. In portions of the Gila National Forest some ranchers claim that the steady increase in elk numbers has caused them to run livestock numbers below that allocated by the United States Forest Service. This has resulted in numerous management challenges including the management of forage utilization for livestock and wildlife. …

Size-Frequency Distribution Of Palaemonetes Pugio In Two New Jersey Estuaries And Predator-Prey Interactions With Fundulus Heterocolitus, Celine Santiago

Theses

Predation by Fundulus heteroclitus is known to be an important factor regulating the abundance and size distribution of Palaemonetes pugio in the salt marsh habitat.

A preliminary study showed that P. pugio from a polluted estuary, Piles Creek, were relatively larger than those found in a more pristine estuary, Little Sheepshead Creek. Possible causes could be differences in competition, inherent environmental components, reproductive effort, or predation. To investigate the differences in size frequency, data on relative abundances of both species and size frequency distribution of P. pugio were collected for comparison from the two estuaries.

It was determined that P. …
