Competitive Abilities Of Native Grasses And Non-Native (Bothriochloa Spp.) Grasses, Cheryl D. Schmidt, Rob Channell Ph.D., Karen R. Hickman, Keith Harmoney, William J. Stark Ph.D.

Biological Sciences Faculty Publications

Old World Bluestems (OWB), introduced from Europe and Asia in the 1920s, recently have begun to raise concerns in the Great Plains. Despite suggestion in the late 1950s that OWB were weedy and negatively impacted biological diversity, they were widely introduced throughout the Great Plains for agricultural purposes. Anecdotal evidence suggests that OWB exhibit invasive characteristics that promote competitive exclusion of native species. The objective of our study was to quantify the competitive abilities of two OWB species (Caucasian bluestem; Bothriochloa bladhii (Retz.) S. T. Blake (= Bothriochloa caucasica (Trin.) C. E. Hubb.) and yellow bluestem; Bothriochloa ischaemum (L.) Keng) …

Evaluación Económica Y Nutricional De Un Programa Complementario De La Fertilización Edáfica A Base De Aminoácidos Y Calcio De Aplicación Foliar En Praderas De Kikuyo - Ryegras En La Sabana De Bogotá, Jairo Alfonso Veloza Gamboa

Zootecnia

La fertilización foliar se ha convertido en una práctica común e importante para los productores, porque permite incrementar la producción de biomasa y por lo tanto incrementar la carga animal. Adicionalmente, se plantea que la fertilización foliar corrige las deficiencias nutrimentales de las plantas, favorece el buen desarrollo de los cultivos y mejora el rendimiento y la calidad del producto. Por lo tanto la fertilización foliar, no pretende sustituir a la fertilización tradicional de los cultivos, pero sí es una práctica que sirve de respaldo, garantía o apoyo para suplementar o completar los requerimientos nutrimentales de un cultivo que no …

Use Of Passive Integrated Transponders In Hatchling Texas Horned Lizards, Scott E. Henke

The Prairie Naturalist

The Texas horned lizard (Phrynosoma cornutum) is a Texas state-threatened species and acquisition of data related to the species' ecology is essential. To accomplish this task individual animals need to be marked. Many marking techniques are available for lizards, however the majority of techniques have been tested on adults only. Studies involving hatchling and juvenile horned lizards are scarce due to problems associated with marking and relocating individuals in these age classes. I demonstrated that injection of passive integrated transponders (PIT's) can safely be used as a marking method in young Texas horned lizards. Thirty-two captive bred hatchling lizards were …

Sex-Specific Feeding Rates And Provisioning Of Fruit To Nestling Bell's Vireo, Greg H. Farley

The Prairie Naturalist

Provisioning of fruit to nestlings and possible sex-specific differences in feeding rate have not been reported for Bell's vireo (Vireo bellii; Brown 1993). While studying nesting ecology of Bell's vireo on Konza Prairie Biological Station, Geary and Riley counties, Kansas, I quantified feeding rate by sex and food type delivered to nestlings. Sex was determined by capturing adults with mist-nets and inspecting for a cloacal protuberance, as well as conducting behavioral observations of uniquely-marked individuals. Males sing regularly while moving around territories, as well as during incubation (Nolan 1960). I assigned "female" to the individual in these socially …

The North Loup Division (Division) is located in east-central Nebraska. Project lands (Figure 1, “North Loup Division, Nebraska, General Map”) are within the drainage basins of the North Loup and Loup Rivers. They extend southeast from near the northwest corner of Valley County through the upland valley of Turtle, Dane, and Mira Creeks and along the North Loup and Loup Rivers from Ord to Fullerton, Nebraska. The irrigable lands are located in Valley, Greeley, Howard, Nance, and Merrick Counties. Diversion facilities are located on the Calamus River in Garfield and Loup Counties and on the North Loup River …

Seasonal Adaptation Of Vegetation Color In Satellite Images, Srinivas Jakkula, Vamsi K.R. Mantena, Ramu Pedada, Yuzhong Shen, Jiang Li, Hamid R. Arabnia (Ed.)

Electrical & Computer Engineering Faculty Publications

Remote sensing techniques like NDVI (Normal Difference vegetative Index) when applied to phenological variations in aerial images, ascertained the seasonal rise and decline of photosynthetic activity in different seasons, resulting in different color tones of vegetation. The rise and fall of NDVI values decide the biological response, either the green up or brown down [1]. Vegetation in green up period appears with more vegetative vigor and during brown down period it has a dry appearance. This paper proposes a novel method that identifies vegetative patterns in satellite images and then alters vegetation color to simulate seasonal changes based on training …

Molecular Diversity And Coat Protein Expression Of Sweet Potato Leaf Curl Virus, Dina Lida Gutierrez Reynoso

LSU Doctoral Dissertations

Leaf curl virus diseases have been reported in sweetpotato throughout the world. One of the causal agents is Sweet potato leaf curl virus (SPLCV) which belongs to the genus Begomovirus (family Geminiviridae). In the United States, SPLCV has been found infecting an ornamental sweetpotato and several breeding lines but not in sweetpotatoes grown for commercial production. SPLCV does not cause symptoms on Beauregard, the predominant sweetpotato cultivar in the US, but it can reduce its yield. Since SPLCV could become an important constraint for sweetpotato production; diagnosis, identification, and characterization are essential steps to develop an effective management program. The …

Spiderwort Is Vnps Wildflower Of The Year, W. John Hayden

Biology Faculty Publications

The VNPS 2008 Wildflower of the Year (WOY) is spiderwort (Tradescantia virginiana). This herbaceous perennial plant occurs throughout much of the eastern portion of the U.S. and is widespread in Virginia. Spiderwort blooms from April to July. The small flowers occur in clusters at the ends of the stems, atop several elongate bracts. Flowers have three petals that range from purple to rose or, rarely, white. Densely hairy stamens provide, perhaps, the easiest way to recognize spiderworts. Also, stalks of spent flowers droop below the flower cluster yielding an aspect reminiscent of spindly spider legs.

2008 Wildflower Of The Year: Virginia Spiderwort, Tradescantia Virginiana, W. John Hayden

Biology Faculty Publications

Spiderwort is an herbaceous perennial that arises from a cluster of rather stout overwintering roots. Stems may be solitary or more commonly clumped, and usually grow unbranched, reaching heights up to 40 cm tall. Stems are smooth or bear scattered short hairs. Leaves are 2—5 per stem, attached by means of a leaf sheath that is 13 cm long. Leaf blades are dull green, elongate, ending in a gradually tapered tip, flat or keeled, smooth (without hairs), and 1—3.5 dm long by 0.5—2.5 cm wide. Flowers occur in tight clusters located at the stem apex; bracts similar to the leaves …

Biology Of The Epichloë-Botanophila Interaction: An Intriguing Association Between Fungi And Insects, Thomas L. Bultman, Adrian Leuchtmann

Thomas L. Bultman

Epichloë fungi (Ascomycota: Clavicipitaceae) are endophytes of grasses that can produce epiphytic stromata on the culms of their hosts. The fungal stromata are visited by Botanophila flies for feeding and egg laying. We review research over the past 20 years that has documented the heterothallic mating system of Epichloë, the mutualistic service of spermatization flies provide for the fungus, and host selection by flies. Flies display an active, stereotypical behavior immediately following oviposition by which spermatia are transferred endozoochorously to stromata. After eggs hatch larvae feed on developing perithecia. Several studies have focused on the cost (consumption of ascospores) to …
