Biotoxins (Field Manual Of Wildlife Diseases), Tonie E. Rocke, Milton Friend

Zoonotics and Wildlife Disease: Publications

Biotoxins are usually defined as poisons that are produced by and derived from the cells or secretions of living organisms. These natural poisons include some of the most toxic agents known and they are found within a wide variety of life forms. Organisms that produce such toxins are generally classified as being venomous or poisonous. The classification of venomous is usually associated with animal life forms such as poisonous reptiles and insects that have highly developed cellular mechanisms for toxin production and that deliver their toxins during a biting (rattlesnake) or stinging (black widow spider) act. Poisonous organisms are generally …

Chemical Toxins (Field Manual Of Wildlife Diseases), Milton Friend

Zoonotics and Wildlife Disease: Publications

Many kinds of potentially harmful chemicals are found in environments used by wildlife. Some chemicals, such as pesticides and polychlorinated biphenyls (PCBs), are synthetic compounds that may become environmental contaminants through their use and application. Other materials, such as selenium and salt, are natural components of some environments, but contaminants of others. Natural and synthetic materials may cause direct poisoning and death, but they also may have adverse effects on wildlife that impair certain biological systems, such as the reproductive and immune systems. This section provides information about some of the environmental contaminants and natural chemicals that commonly cause avian …

Investigating Ground And Surface Water In The Republican River Basin Of Nebraska Using Water Chemistry And Environmental Isotopes, Jennifer J. Schellpeper

School of Natural Resources: Dissertations, Theses, and Student Research

Recent legal battles concerning water use initiated an investigation of the stream/aquifer relationships in the Republican River Basin located in southwest Nebraska. Ground and surface water was analyzed for tritium, deuterium, ¹⁸O, and major ions. Temperature, pH, conductivity and alkalinity were determined on-site. Samples were collected during 1997 and 1998 from irrigation wells throughout the entire basin. Localized interactions between groundwater and surface water were examined during twenty-four hour pump tests performed on the irrigation wells screened in the alluvium along the river valley and its tributaries. These data show there are differences between the ground and surface waters …

Bacterial Diseases (Field Manual Of Wildlife Diseases), Milton Friend

Zoonotics and Wildlife Disease: Publications

Diseases caused by bacteria are a more common cause of mortality in wild birds than are those caused by viruses. In addition to infection, some bacteria cause disease as a result of potent toxins that they produce. Bacteria of the genus Clostridium are responsible for more wild bird deaths than are other disease agents. Clostridium botulinum, which causes avian botulism, is primarily a form of food poisoning and it is included within the section on biotoxins (see Chapter 38). Other Clostridium sp. that colonize intestinal tissues produce toxins that cause severe hemorrhaging of the intestine, thus leading to tissue …

Viral Diseases (Field Manual Of Wildlife Diseases), Douglas E. Docherty

Zoonotics and Wildlife Disease: Publications

Historically, viral diseases have not been recognized as major causes of illness and death in North American wild birds. Until relatively recently, this may have been due to inadequate technology to culture and identify these organisms. Unlike bacteria, viruses are too small to be seen under the light microscope and they cannot be grown on artificial media. Nevertheless, studies of infectious diseases caused by viruses have often predated discovery of the causative agents by many years as evidenced by smallpox immunizations being used centuries before that virus was identified. The isolations of a tobacco mosaic virus in 1892 and foot …

Miscellaneous Diseases (Field Manual Of Wildlife Diseases), Milton Friend, Nancy J. Thomas

Zoonotics and Wildlife Disease: Publications

The fact that “Nature is far from benign” is clearly evident from the preceding chapters of this Manual. The diseases and other conditions described are the proverbial “tip of the iceberg” relative to the number of specific causes of ill health and death for free-ranging wild birds, but the wild bird health problems described account for most major wild bird disease conditions seen within the United States. However, the full toll from disease involves many other causes of illness and death that individually may cause substantial die-offs. Two examples of these other causes of die-offs are the deaths of Canada …

Amplification And Methylation Of An Esterase Gene Associated With Insecticide-Resistance In Greenbugs, Schizaphis Graminum (Rondani) (Homoptera: Aphididae), Midori Ono, Jeffrey J. Swanson, Linda M. Field, Alan L. Devonshire, Blair D. Siegfried

Department of Entomology: Faculty Publications

The greenbug aphid, Schizaphis graminum (Rondani) has developed resistance to organophosphorus insecticides by the over-production of esterases that have been classified as Type I and Type II. The first twenty N-terminal amino acids of the Type I esterase were determined and used to design an oligonucleotide, which in conjunction with an active site primer derived from conserved sequences of other insect esterases and two internal primers specific for esterases from another aphid species resulted in a 0.85 kb genomic DNA fragment from resistant greenbugs. This was extended by 5′ RACE which provided approximately 1.2 kb of the 5′ end …

Melanoma Chondroitin Sulphate Proteoglycan Regulates Cell Spreading Through Cdc42, Ack-1 And P130Cas, Kathryn M. Eisenmann, James B. Mccarthy, Melanie A. Simpson, Patricia J. Keely, Jun-Lin Guan, Kouichi Tachibana, Louis Lim, Ed Manser, Leo T. Furcht, Joji Iida

Department of Biochemistry: Faculty Publications

Melanoma chondroitin sulphate proteoglycan (MCSP) is a cell-surface antigen that has been implicated in the growth and invasion of melanoma tumors. Although this antigen is expressed early in melanoma progression, its biological function is unknown. MCSP can stimulate the integrin-α4β1-mediated adhesion and spreading of melanoma cells. Here we show that stimulated MCSP recruits tyrosine- phosphorylated p130cas, an adaptor protein important in tumor cell motility and invasion. MCSP stimulation also results in a pronounced activation and recruitment of the Rho-family GTPase Cdc42. MCSP-induced spreading of melanoma cells is dependent upon active Cdc42, a Cdc42-associated tyrosine kinase (Ack-1) and tyrosine phosphorylation of …

Birth Cohort Differences In Features Of Antisocial Alcoholism Among Men And Women, S. F. Stoltenberg, E. M. Hill, S. A. Mudd, F. C. Blow, R. A. Zucker

Department of Psychology: Faculty Publications

Background: This study examines the relations between birth cohort, gender, and family history of alcohol problems on alcohol dependence, and on the endorsement of alcohol abuse/dependence symptoms related to antisocial behavior. Methods: Men (n = 1365) and women (n = 625) were recruited from the community, hospitals, and other treatment sites and were given a structured diagnostic interview. Data were analyzed by using logistic regression. Results: Age of first regular alcohol use was lower in more recent birth cohorts for both men and women, with those born in the most recent cohort reporting earliest regular use. The decline …

Wildlife-Caused Losses For Producers Of Channel Catfish Ictalurus Punctatus In 1996, Alice P. Wywialowski

United States Department of Agriculture Wildlife Services: Staff Publications

The National Agricultural Statistics Service surveyed by telephone and mail in January and February 1997 all known producers of channel catfish Ictalurus punctatus to acquire current information about wildlife-caused losses in calendar year 1996. Many producers tried to prevent wildlife-caused losses of their catfish by shooting (57%), vehicle patrol (55%), or frightening (36%), at an estimated cost of >$5 million. Yet, 69% of catfish produces cited some wildlife-caused losses. Birds were most frequently cited as a cause of losses, and double-crested cormorants Phalacrocorax auritus was the species cited most frequently (53%). The next most frequently cited bids were herons Ardea …

Fatal Cysticercosis By Taenia Crassiceps (Cyclophyllidea: Taeniidae) In A Presumed Immunocompromised Canine Host, Eric P. Hoberg, William Ebinger, James A. Render

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cysticercosis in a canine host (Canis jamiliaris) attributable to the taeniid cestode Taenia crassiceps is reported for the first time in North America. Numerous parent and daughter cysticerci occurred in a massive intrapleural and intraperitoneal infection in an apparently immunocompromised host. The largest cysticerci were ovoid to elongate. 5-9 mm in maximum length. and armed with 32-34 rostellar hooks in two rows; small hooks measured 114-143 μm long (avg. = 124 ± 8.2 μm). and large hooks were 156-180 μm (avg. = 163 ± 7.4 μm). Taenia crassiceps is widespread in boreal North America and, like a number …

New Mammalian Selenocysteine-Containing Proteins Identified With An Algorithm That Searches For Selenocysteine Insertion Sequence Elements, Gregory V. Kryukov, Valentin M. Kryukov, Vadim N. Gladyshev

Vadim Gladyshev Publications

Mammalian selenium-containing proteins identified thus far contain selenium in the form of a selenocysteine residue encoded by UGA. These proteins lack common amino acid sequence motifs, but 3’-untranslated regions of selenoprotein genes contain a common stem-loop structure, selenocysteine insertion sequence (SECIS) element, that is necessary for decoding UGA as selenocysteine rather than a stop signal. We describe here a computer program, SECISearch, that identifies mammalian selenoprotein genes by recognizing SECIS elements on the basis of their primary and secondary structures and free energy requirements. When SECISearch was applied to search human dbEST, two new mammalian selenoproteins, designated SelT and SelR, …

Remote Sensing Of Photosynthetic-Light-Use Efficiency Of Boreal Forest, Caroline J. Nichol, Karl F. Huemmrich, T. Andrew Black, Paul G. Jarvis, Charles L. Walthall, John Grace, Forrest G. Hall

United States National Aeronautics and Space Administration: Publications

Using a helicopter-mounted portable spectroradiometer and continuous eddy covariance data we were able to evaluate the photochemical reflectance index (PRI) as an indicator of canopy photosynthetic light-use efficiency (LUE) in four boreal forest species during the Boreal Ecosystem Atmosphere experiment (BOREAS). PRI was calculated from narrow waveband reflectance data and correlated with LUE calculated from eddy covariance data. Significant linear correlations were found between PRI and LUE when the four species were grouped together and when divided into functional type: coniferous and deciduous. Data from the helicopter-mounted spectroradiometer were then averaged to represent data generated by the Airborne Visible Infrared …

Perceptions Of Couple Functioning Among Female Survivors Of Child Sexual Abuse, David Dilillo, Patricia J. Long

Department of Psychology: Faculty Publications

A sample of 51 college women retrospectively reporting a history of childhood sexual abuse and 91 women failing to report such a history was examined in order to investigate the relationship between victimization history and survivors' self-reports of functioning in adult intimate relationships. Specifically, relationship satisfaction, communication, and trust were examined in heterosexual relationships of at least six months' duration. As hypothesized, even when demographic differences between groups were controlled, survivors reported significantly less relationship satisfaction, poorer communication, and lower levels of trust in their partners than did women with no history of sexual abuse. The implications of these results …

Fully Biologically Active In Vitro Transcripts Of The Eriophyid Mite-Transmitted Wheat Streak Mosaic Tritimovirus, Il-Ryong Choi, Roy C. French, Gary L. Hein, Drake C. Stenger

Department of Plant Pathology: Faculty Publications

Infectious RNA of wheat streak mosaic virus (WSMV) has been produced using a full-length cDNA clone as a template for in vitro transcription with SP6 RNA polymerase. Infectivity was dependent on the use of template plasmid DNA that had not undergone spontaneous rearrangement during amplification in Escherichia coli. The presence of WSMV in systemically infected wheat plants inoculated with in vitro transcripts was confirmed by reverse-transcription polymerase chain reaction of the WSMV P3 gene and by accumulation of WSMV coat protein as detected by immunoblotting. Maintenance of the full-length WSMV cDNA in the high copy number plasmid pUC18 was problematic …

Why Are Girls Less Physically Aggressive Than Boys? Personality And Parenting Mediators Of Physical Aggression, Gustavo Carlo, Marcela Raffaelli, Deborah J. Laible, Kathryn A. Meyer

Department of Psychology: Faculty Publications

The primary goal of the present analysis was to determine whether the commonly observed gender difference in physical aggression could be accounted for by gender differences in selected personality and social contextual factors. Eighty-nine adolescents (M age = 16.0; 52% female; 53% European-Americans, 38% Latinos) completed self-report measures, including sympathy (empathic concern and perspective taking) and parental involvement (support and monitoring). Mediation analyses revealed that relatively high levels of both empathic concern and parental monitoring accounted for relatively low levels of physical aggression. In addition, sympathy (for males) and parental involvement (males and females) were negatively related to physical aggression. …

Do Mothers And Teens Disagree About Sexual Communication? A Methodological Reappraisal, Marcela Raffaelli, Lori A. Smart, Sarah C. Van Horn, Angela D. Hohbein, Jennifer E. Kline, Wei-Lik Chan

Department of Psychology: Faculty Publications

This study investigated whether parent-teen disagreement in reports of sexual discussions is due to methodological factors. Forty-four mothers and their 12- to 15-yearold daughters (n = 18) and sons (n = 26) completed parallel questionnaires including measures of communication about 18 different sexual topics during the teen’s entire life and during the past year. Analyses examined whether congruence rates were infl uenced by the use of global as compared to specifi c items, assessment of conversations during the teen’s entire life as compared to the past year, and use of forced-choice as opposed to continuous-response categories. Taken as a whole, …
