Impact Of Reduced Lignin On Plant Fitness, J. F, Pedersen, K. P. Vogel, D. L. Funnell

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

Lignin content of crop plants has been reduced by traditional plant breeding, natural and induced mutations, and insertion of transgenes. The effects of these genes and associated lower lignin content have been examined in terms of agricultural fitness or with regard to economically harvestable yields of useful plant products, or, in the case of some perennial species, survivability over multiple years. In general, crop yields are depressed by significant reductions in lignin content. Other negative effects observed in plants with lowered lignin contents include lodging and reduction of long-term survival of some perennial species. However, the interactions of genes involved …

RECORDS OF THE EASTERN RED BAT ON THE NORTHERN FRONT RANGE OF COLORADO, …

Records Of The Eastern Red Bat On The Northern Front Range Of Colorado, Daniel J. Neubaum

The Prairie Naturalist

Although common in deciduous forest throughout the Midwest and east-central states, the eastern red bat (Lasiurus borealis) is rare in Colorado (Armstrong et al. 1994, Fitzgerald et al. 1994). However, this species has the potential to extend its range because belts of eastern deciduous forest habitat have expanded across western prairies and reached the Front Range of Colorado over the last 100 years (Knopf 1986). The eastern red bat ranges from Canada southward across the United States to northeastern New Mexico with most records occurring east of the Continental Divide (Hall 1981, Shump and Shump 1982, Cryan 2003). …

Lesser Prairie-Chicken Use Of Harvested Corn Fields During Fall And Winter In Southwestern Kansas, Gregory C. Salter, Robert J. Robel, Kenneth E. Kemp

The Prairie Naturalist

The lesser prairie-chicken (Tympanuchus pallidicinctus) has declined in numbers in Kansas primarily due to the conversion of sand sagebrush (Artemisia .filifolia) prairie to cropland. The lesser prairie-chicken in Finney County, Kansas exists primarily in large fragments of sand sagebrush prairie, and it forages during fall and winter on waste grain in harvested com (Zea mays) fields adjacent to prairie fragments. We used radio-telemetry to monitor lesser prairie chicken locations and found no significant relationship between numbers of bird locations and amounts of waste grain on the ground in harvested com fields. Even the harvested …

Alfalfa: Crop For The Future, N. P. Martin, R. D. Hatfield, D. R. Mertens, P. J. Weimer

Kentucky Alfalfa and Stored Forage Conference

Alfalfa use by dairy cattle has decreased in recent years because of excessive nonprotein nitrogen and low fiber digestibility. Ideal attributes for plant modification of alfalfa may include those that increase milk potential per acre and/or per ton, enhance digestible NDF, improve protein content and amino acid balance, improve agronomic traits for insect protection (safer forage supply), herbicide tolerance, virus resistance, drought tolerance, cold tolerance, improved mineral availability and enhanced yield. Progress in attaining these attributes will accelerate with the use of biotechnology. Livestock and hay enterprises will benefit from alfalfa that is less prone to contain mycotoxins or toxic …

Growing Alfalfa For Wildlife, Don Ball

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has long been recognized as a superb forage crop, which is why it is widely grown for dairy cattle, horses, sheep, and many other types of domesticated forage-consuming animals. Reasons for its popularity include wide adaptation, excellent nutritive value, good yield potential, perennial growth habit, a long growing season, and the fact that (in association with Rhizobium bacteria) it is a nitrogen-fixing legume that does not require periodic applications of nitrogen fertilizer.

Alfalfa Hay For Horses (And Horse Owners!), Laurie Lawrence, Bryan Cassill

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is one of the most common hays fed to horses in Kentucky. Other hays that are often used include timothy and orchardgrass. As a legume, alfalfa has many nutritional advantages over timothy or orchardgrass. Alfalfa hay contains more protein and calcium than grass hays and thus is an excellent source of these nutrients for broodmares and growing horses. Another legume that may be useful as a hay for horses is red clover. Nutritionally, red clover has many of the same advantages as alfalfa. However, red clover has some non-nutritional characteristics which have traditionally limited its popularity with horse owners. …

Agriculture contributes to the economy through direct agricultural production and value-added processing which generates economic activity in other parts of the economy.

Silvopasture Water And Fencing Systems For Cattle, Sid Brantly

Agroforestry Notes (USDA-NAC)

Silvopasture is an agroforestry system that combines grazing livestock with growing trees for a timber product. Creating small, fenced paddocks and rotating cattle builds in "recovery periods" for the forage and protects the soil and trees. In a silvopastoral system, grazing recovery periods can only be achieved when well-designed livestock water supplies and cross fences are used. Fortunately, technological advances in livestock water system design and fence materials have helped to create a feasible working environment where rotating livestock from one silvopasture paddock to another can be both convenient and affordable. However, some special considerations must be given to water …

Functional Specialization Of Chlamydomonas Reinhardtii Cytosolic Thioredoxin H1 In The Response To Alkylation-Induced Dna Damage, Nandita Sarkar, Stephane Lemaire, Danxia Wu-Scharf, Emmanuelle Issakidis-Bourguet, Heriberto D. Cerutti

Center for Plant Science Innovation: Faculty Publications

DNA damage occurs as a by-product of intrinsic cellular processes, like DNA replication, or as a consequence of exposure to genotoxic agents. Organisms have evolved multiple mechanisms to avoid, tolerate, or repair DNA lesions. To gain insight into these processes, we have isolated mutants hypersensitive to DNA damaging agents in the green alga Chlamydomonas reinhardtii. One mutant, Ble-1, showed decreased survival when it was treated with methyl methanesulfonate (MMS), bleomycin, or hydrogen peroxide (H₂O₂) but behaved like the wild type when it was exposed to UVC irradiation. Ble-1 carries an extensive chromosomal deletion that includes …

The impact of filamentous fungi on human welfare has never been greater. Fungi are acknowledged as the most economically devastating plant pathogens (1) and are attaining increasing notoriety for their ability to cause life-threatening infections in humans (57, 71), and fungal products sustain a billion dollar manufacturing industry (70). The tools available to study filamentous fungi are more sophisticated than ever and include the complete annotated genome sequences of multiple filamentous fungi (12), resources being made available through various functional genomics projects, and advanced bioimaging methods, including high-resolution live-cell imaging (20, 32) and electron tomography (19, 50). The increasing impact …

Code Of Practice For The Use Of Agricultural And Veterinary Chemicals In Western Australia, Peter Rutherford

Bulletins 4000 -

Agricultural and veterinary chemicals are a critically important input to modern farming systems. There is, however an increasing responsibility on the spray operator and his supervisor to use them with utmost safety. An effective way of providing the “rules” of safe chemical use is through a Code of Practice, the concept of which arose because of the increase in new and emerging agricultural industries and their impact on traditional uses of agricultural chemicals.

Colonization Of Gnotobiotic Piglets By A Luxs Mutant Strain Of Escherichia Coli O157:H7, Dianna M. Jordan, Vanessa Sperandio, James B. Kaper, Evelyn A. Dean-Nystrom, Harley W. Moon

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

Gnotobiotic piglets inoculated with Escherichia coli O157:H7, its luxS mutant derivative, or nonpathogenic E. coli were evaluated for attaching and effacing lesions. Although no differences in clinical symptoms were seen between pigs inoculated with the parent and those inoculated with the luxS mutant, the luxS mutant-inoculated pigs had a lower frequency of attaching and effacing lesions in the spiral colon than parent strain-inoculated pigs.

Improved Pasture Systems Make Sense... And Dollars Too!, Jason Tower

Forage Symposium at the Kentucky Cattlemen’s Convention

Talk to most any beef producer and he can tell you the facts of his beef operation. Many cattlemen can go back three or four generation on a cow’s pedigree. He can tell you what bull was used on the farm for each of the last ten years. More than likely he can tell you the number of calves he weaned last year. He can tell you the average weight of those calves and if he topped the market, there is no doubt you will soon learn what price he received for the calves. Ask this cattleman what it cost …

Corn As A Grazing Crop: An Option For Extending The Grazing Season In Kentucky, David C. Ditsch, John T. Johns, Steven G. Isaacs, Tyler B. Mark, C. D. Lee

Forage Symposium at the Kentucky Cattlemen’s Convention

Grazing is the cheapest way to feed cattle on a cost per pound of nutrient basis. However, producers with limited land resources in Kentucky have been able to use commodities or grain by-products to increase cattle numbers due to low cost and availability of these inputs. Extending the grazing season is one solution that would enable producers to reduce cost and expand production with little or no impact on the environment.

Forage Quality--Back To Basics, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

Forage quality means different things to different people. Forage quality varies tremendously among and within forage crops. Forage quality needs varies among and within animal species. Forage quality has been defined in terms of protein, fiber, lignin content, relative feed value, relative forage quality, color, smell, leafiness, fineness of stems, total digestible nutrients, and other physical and/or chemical components. All of these components have merit, but all fall short of clearly defining forage quality. Factors such as average daily gains, conception rates, milk production, wool production, etc. are reliable indicators of forage quality. Forage quality can be defined as: the …

Day Vs. Night Sampling For Spiders In Grape Vineyards, Michael J. Costello, Kent M. Daane

Horticulture and Crop Science

We compared day sampling (between 0700 and 1100) and night sampling (between 1900 and 2300) of spiders on grapevines in a California vineyard in 1993 and 1994, shaking spiders from the vines onto a drop cloth and vacuuming them up. Pooled density of the seven most abundant spider species did not differ significantly between day and night sampling, nor did density of Cheiracanthium inclusum (Miturgidae), Trachelas pacificus (Corrinidae), Oxyopes spp. (Oxyopidae) or Neoscona oaxacensis (Araneidae). Under day sampling Metaphidippus vitis (Salticidae) was 60% more abundant and Hololena nedra (Agelenidae) more than 2.5 fold more abundant than under night sampling. Daytime …

A Two-Year Seasonal Analysis Of Wetland Vegetation At The Mcclintic Wildlife Management Area In Mason County, West Virginia, Anne Carrington Blankenship

Theses, Dissertations and Capstones

Disturbances play a key role in the structure of ecosystems. Most ecosystems are subject to several different disturbance regimes that occur at different temporal and spatial scales. Studying the effects of disturbances can lead to a better understanding of a vegetative community’s future productivity. However, in order to understand the effects of disturbance, a vegetative community should first be studied before the disturbance occurs. This study analyzes the composition and seasonal variations of vegetative communities in and around four ponds at the McClintic Wildlife Management Area in Mason County, West Virginia during two growing seasons prior to remediation activities in …
