A Review Of The Classification Of The Genus Hydrastis (Ranunculaceae), Carl S. Keener Dec 1993

A Review Of The Classification Of The Genus Hydrastis (Ranunculaceae), Carl S. Keener

Aliso: A Journal of Systematic and Evolutionary Botany

The genus Hydrastis has been variously classified as a monotypic taxon in the Ranunculaceae, the Berberidaceae, the Glaucidiaceae, or its own monogeneric family, the Hydrastidaceae. The objectives of this paper were 1) to review the previous classifications of Hydrastis and 2) to critique a recent paper by Tobe and Keating reevaluating the classification of the genus based on comparative morphological and anatomical studies. One conclusion of this review was that Tobe and Keating overlooked certain important papers which might have substantially altered their conclusions, viz., that Hydrastis is sufficiently distinct from the other genera of the Ranunculaceae to warrant a ...


Laboulbeniales On Semiaquatic Heteroptera. Vi. The Genus Tavaresiella, Richard K. Benjamin Dec 1993

Laboulbeniales On Semiaquatic Heteroptera. Vi. The Genus Tavaresiella, Richard K. Benjamin

Aliso: A Journal of Systematic and Evolutionary Botany

Majewski's original circumscriptions of Tavaresiella (Laboulbeniales; Laboulbeniaceae; Stigmatomycetinae) and its type species, T. hebri, were emended in this study of the genus. In addition, three new species were described, T. majewskii, T. polhemi, and T. santamariae. These, like the type species, occurred on true bugs of the family Hebridae (Heteroptera). A key to the species was provided, and ali were described and illustrated with line drawings and photographs. Aspects of ascomatic structure and development were summarized, and the genus was compared with other genera of the subtribe having similar characteristics.


A Phytochemical Study Of Selected Podostemaceae, Virginia Romo Contreras, Ron Scogin, C. Thomas Philbrick, Alejandro Novelo R. Dec 1993

A Phytochemical Study Of Selected Podostemaceae, Virginia Romo Contreras, Ron Scogin, C. Thomas Philbrick, Alejandro Novelo R.

Aliso: A Journal of Systematic and Evolutionary Botany

Podostemum ceratophyllum contains γ-mangostin and its 6-glucoside. The aglycone is also present in Marathrum, Oserya, and Vanroyenella, but is absent from Tristicha. Anthocyanins were identified from all genera, but no additional fiavonoids were detected. Condensed and hydrolyzable tannins, iridoids, cyanogenic glycosides, and alkaloids were lacking in all Podostemaceae examined. Phytochemical constituents do not clarify the uncertain systematic affinity ofPodostemaceae, but emphasize the generally accepted taxonomic isolation of this family.


Wood Anatomy Of Sabiaceae (S.L.), Sherwin Carlquist, Peter L. Morrell, Steven R. Manchester Dec 1993

Wood Anatomy Of Sabiaceae (S.L.), Sherwin Carlquist, Peter L. Morrell, Steven R. Manchester

Aliso: A Journal of Systematic and Evolutionary Botany

Quantitative and qualitative data were offered for 30 taxa of Meliosma and one species each of Ophiocaryon and Sabia; qualitative data were available for additional species of Meliosma and Sabia. For a small family restricted to mesic sites, Sabiaceae had a wide range of wood anatomical expressions (e.g., long scalariform to simple perforation plates; heterocellular to homocellular multiseriate rays; tracheids, fiber-tracheids, or libriform fibers as imperforate tracheary elements; presence or absence of silica bodies and calcium oxalate crystals in rays). Growth ring type, vessel diameter, vessel density, and vessel element length were sensitively related to ecology, but to degree ...


Wood Anatomy And Relationships Of Santalaceae I. Acanthosyris, Jodina, And Myoschilos, Carlos Alejandro Norverto Dec 1993

Wood Anatomy And Relationships Of Santalaceae I. Acanthosyris, Jodina, And Myoschilos, Carlos Alejandro Norverto

Aliso: A Journal of Systematic and Evolutionary Botany

Study of the wood of Acanthosyris, Jodina, and Myoschilos confirmed a close relationship between Santalaceae and Olacaceae. Features important for defining the three genera and for determining relationships between them and with Schoepfia, which belongs to Olacaceae, are reported for the first time: vestured vessel walls, unilaterally compound pits, perforated ray cells, and druses.

Evolutionary Perspectives On Animalivory, Patricia W. Freeman Dec 1993

Evolutionary Perspectives On Animalivory, Patricia W. Freeman

Mammalogy Papers: University of Nebraska State Museum

Derived from insectivorous ancestors, microchiropteran bats have diversified into a remarkable array of feeding habits. Cranial and dental characteristics mirror this diversity. Insectivorous predators of hard-shelled prey have thicker jaws, well-developed cranial crests, fewer but larger teeth, longer canines and abbreviated M3s than species that take soft items. Carnivorous bats have more elongate skulls, larger brain volumes and larger pinnae, lengthened metastylar ridges, and larger protoconids compared to insectivores. Animalivorous species have large ectoloph areas compared to frugivorous and nectarivorous species, but animalivores and frugivores have large tooth areas relative to palatal area compared to nectarivores. Frugivores sacrifice ectoloph for ...

Discounting Property Values At Death, Neil E. Harl Dec 1993

Discounting Property Values At Death, Neil E. Harl

Agricultural Law Digest

The idea that property values can be discounted at death for a minority interest and for non-marketability is well established. Although discounting cannot be applied in addition to any reduction in value from special use valuation of land, discounting of corporate stock may produce a lower stock value than claiming special use valuation on the corporation -owned land.


A Simple Basic Explanation Of Cow Nutrition, Ivan G. Rush Dec 1993

A Simple Basic Explanation Of Cow Nutrition, Ivan G. Rush

Range Beef Cow Symposium

Cattle producers in many ways have expertise in nutrition. Each day when cattle are fed or when grazing, they are taking in nutrients (protein, energy, minerals, etc.) that are vital for their life and production. Cattlemen are responsible for providing the feeds that supply the nutrients for the beef animal. If provided in the proper balance and portions at an economical level then the desired results should be obtained. If shortages occur with any required nutrient or if the nutrients are fed in excess or the sources are extremely costly then economic losses will be experienced. Because the largest cost ...


Effects Of Supplementation On Intake And Utilization On Harvested Forages, David W. Sanson Dec 1993

Effects Of Supplementation On Intake And Utilization On Harvested Forages, David W. Sanson

Range Beef Cow Symposium

A frequent question asked by beef cattle producers is what supplement should be used. Prior to asking this question, it should be determined if a supplement is necessary. To answer this question, the nutrient requirements of the animal to meet the desired production level must be established. Next, it should be determined if current feed resources will meet these needs. It may be possible to shift grazing practices or to adjust feeding levels and meet the requirements. Once it is established that a supplement must be used, then the supplement that will improve the utilization of the base diet should ...


Precalving Nutrition/Birth Weight Interaction And Rebreeding Efficiency, Robert P. Wettemann Dec 1993

Precalving Nutrition/Birth Weight Interaction And Rebreeding Efficiency, Robert P. Wettemann

Range Beef Cow Symposium

Profitability of calf production can be greatly increased by improvements in reproductive efficiency. Losses in income are associated with nonpregnant cows, calves that are born late in the calving season and death of calves at birth. Too many heifers and cows exposed to bulls during a breeding season do not become pregnant and wean a calf the next year. A major reason for the inefficiency is that cows are not pregnant at the end of breeding because many have not been in estrus and bred by the bulls. In addition, some cows do not start estrous cycles until late in ...


Antibody Levels In Beef Calves (Birth Through Weaning) Following Clostridium Perfringens Type C Toxoid And/Or Antitoxin Administration, Robert P. Ellis, David L. Morris, Roberta J. Todd, Roukaya Osman Dec 1993

Antibody Levels In Beef Calves (Birth Through Weaning) Following Clostridium Perfringens Type C Toxoid And/Or Antitoxin Administration, Robert P. Ellis, David L. Morris, Roberta J. Todd, Roukaya Osman

Range Beef Cow Symposium

According to National Cattlemen's Association data, there are approximately 35 million beef cows and 10 million dairy cows in the United States. Combining pre-calving, pre-weaning, yearling, breeding bulls and replacement heifer vaccination opportunities to utilize Clostridial immunization programs, it is estimated that well in excess of 100 million doses of various Clostridial containing products are used each year. Knowing which products stimulate satisfactory antibody levels and their duration of response is an essential part of making informed recommendations to producers for controlling disease. Presently, non-industry, controlled field studies assessing Clostridial products are not available.

Specifically, Clostridium perfringens Type C ...

Calf Scours: Prevention And Treatment, Franklyn Garry Dec 1993

Calf Scours: Prevention And Treatment, Franklyn Garry

Range Beef Cow Symposium

There are numerous causes of disease and death in nursing beef calves. Within the first several days of life, the leading causes of beef calf disease are metabolic and behavioral problems, many of which are the direct or indirect result of dystocia. Thereafter, the most common calfhood problems are infectious diseases. Infections of the respiratory and gastrointestinal system account for the overwhelming majority of calf disease and death in the United States. Gastrointestinal diseases tend to be most common within the first month of life, while the respiratory diseases tend to be more important after that time.

There are numerous ...


Cattle Abortions - Causes And Prevention, Michael Yaeger Dec 1993

Cattle Abortions - Causes And Prevention, Michael Yaeger

Range Beef Cow Symposium

Abortions in cattle may result from a broad range of causes. Abortions may be idiopathic (occurring without known cause) or the result of metabolic or hormonal abnormalities, nutritional deficiencies, trauma, toxicities, or infectious processes. For this presentation, information collected from diagnostic laboratories in South Dakota, Nebraska and Wyoming has been summarized in order to distill this broad subject down to its most important aspects. This presentation will examine the various infectious causes of abortion and focus on those diseases which diagnostic results indicate are the most important contagious causes of abortion.

Before beginning the discussion of specific causes of abortion ...


What Does Biotechnology Have To Offer Beef Cattle Reproduction? Costs And Practical Value, George E. Seidel Jr. Dec 1993

What Does Biotechnology Have To Offer Beef Cattle Reproduction? Costs And Practical Value, George E. Seidel Jr.

Range Beef Cow Symposium

The term "reproductive biotechnology" has different meanings in different circumstances. I will use a broad definition that ranges from estrus synchronization to DNA manipulation. By far the most relevant and important reproductive biotechnology for beef cattle production is artificial insemination. It is shocking that only around 5% of calves of beef cattle breeds in this country are sired via this biotechnology, but I will not discuss artificial insemination further because the methodology, costs, and applications are well known. In my opinion, the second most important reproductive biotechnology is estrous cycle synchronization; I'll not cover this further because there will ...


Bull Power: Productivity And Profitability, Garth W. Boyd Dec 1993

Bull Power: Productivity And Profitability, Garth W. Boyd

Range Beef Cow Symposium

One of the biggest challenges facing cow/calf producers today is cutting their costs of production. One possible strategy for lowering costs is to increase the production efficiency of the cow herd. A key area to focus on is the reproductive function of the beef bull because natural mating accounts for over 95% of the pregnancies achieved each year in the 33.7 million beef cows in the U.S.

It is becoming apparent that perhaps because of increased selection pressure on scrotal circumference, the modern beef bull is more fertile than the bull of yesterday. Yet, according to the ...


Estrous Synchronization In Lactating Cows, Doug L. Hixon Dec 1993

Estrous Synchronization In Lactating Cows, Doug L. Hixon

Range Beef Cow Symposium

The objective of any successful synchronization program is to manipulate the estrous cycle of normally cycling females so that a large percentage will exhibit estrus with normal fertility at a pre-determined time. Synchronization programs have typically been most successful with heifers due to a lack of interference from extraneous factors. Since minimum age and weight are the primary prerequisites for a heifer of a particular breed to reach puberty, a nutritional program can be designed to allow the majority of heifers to reach their appropriate target weight by 13-14 months of age. Provided there are no health problems, or extreme ...


Using Ultrasound Technology In Reproduction Management, Douglas D. Zalesky Dec 1993

Using Ultrasound Technology In Reproduction Management, Douglas D. Zalesky

Range Beef Cow Symposium

Reproductive performance in cow-calf operations is one of, if not the most important factor affecting profitability in a herd. Several economic studies have suggested that reproductive traits are 5 to 10 times more important than growth traits and 5 to 20 times more important than carcass traits in determining the net profitability in an operation. Therefore, achieving high levels of reproductive efficiency should be the top or one of the top goals of any cow-calf operation.

Ultrasound technology is by no means a new technology. Its use in live animals was first described in 1950 by J.J. Wild. He ...


Factors Affecting Calving Difficulty, R. A. Bellows Dec 1993

Factors Affecting Calving Difficulty, R. A. Bellows

Range Beef Cow Symposium

Calf deaths resulting from difficult calving (dystocia) cause a major reduction in the net calf crop and income realized by beef producers. Based on 1993 projected figures, a 5% increase in animals available for sale in the U.S. could potentially increase gross receipts by over $1.5 billion annually. These same projection figures also suggest that losses attributed to calf deaths from dystocia alone exceed $750 million annually. Identifying ways to decrease dystocia and the accompanying calf deaths is the subject of this paper.


Problems Handling Dystocia, Robert G. Mortimer Dec 1993

Problems Handling Dystocia, Robert G. Mortimer

Range Beef Cow Symposium

The recognition of abnormal calving (dystocia) comes FIRST from a basic understanding of normal calving. From this understanding, the establishment of guidelines for observation of cattle and for intervention will reduce calf losses . In Colorado, as part of a pilot program of the National Animal Health Monitoring System (NAHMS), two-thirds of the costs of disease losses were associated with death loss. From a subset of 73 of the 86 NAHMS herds in studied in 1986-87 in 24,396 births, 4.5% of the calves were lost. Of the 4.5% losses, 34% were attributed to dystocia related losses. In addition ...


Overlooked And Neglected Principles Of Grazing Management, Patrick E. Reese Dec 1993

Overlooked And Neglected Principles Of Grazing Management, Patrick E. Reese

Range Beef Cow Symposium

The more one understands about resources critical to ranching the more likely one is to survive hard times. There are many distractions in the range livestock industry from day to day activities to technology overloads at educational meetings. As you sift through your experiences and observations do you ever ask the question, "What will I teach the next generation of management to improve their chances of success?". Hopefully, the answer is, "the basic fundamentals". New technologies, new words and new strategies do not change fundamental principles of rangeland management.


Cost Control Using Economic Analysis And Spa, Paul H. Gutierrez Dec 1993

Cost Control Using Economic Analysis And Spa, Paul H. Gutierrez

Range Beef Cow Symposium

The primary activities of management include planning, organizing, directing and control. The most important and most challenging is control)the process of analyzing, evaluating and interpreting the production and financial performance of the business, so the business manager can make informed business management decision. After almost two years of working with beef cattle business managers and gaining an understanding of the recommendations of the Farm Financial Standards Task Force (FFSTF) and the National Cattlemen's Association-Integrated Resource Management-Standardized Performance Analysis (NCA-IRM-SPA) subcommittee guidelines, has made a believer out of me now. Why? A complete accounting analysis, such as that provided ...


Effects Of Early Weaning On High Growth Calves And Subsequent Carcass Characteristics, R. H. Pritchard Dec 1993

Effects Of Early Weaning On High Growth Calves And Subsequent Carcass Characteristics, R. H. Pritchard

Range Beef Cow Symposium

Historically, early weaning has been considered one of those things you might have to do in drought years. We do it because the cow-calf pairs are not realizing their production potential when running on dried up rangeland. For the rancher that has invested in quality bulls and is producing high growth potential calves, the problem is the same, only the circumstances are different. In years when grass production is adequate, high growth potential calves are not receiving adequate nutrition to express their genetic potential. The typical management adjustment in this situation is to creep feed or pre-condition the calves. Either ...
