Formulating Mineral Supplements For Beef Cows, Cody Wright

SDSU Extension Extra Archives

Mineral nutrition of beef cattle is one component of ruminant nutrition that most producers address by simply purchasing a commercial supplement for their herd. However, this practice, while generally effective, can be wasteful. In many cases, commercial mineral supplements are formulated to provide in excess of 100% of the nutrient requirements for many different minerals. However, at least a portion of the minerals required by beef cows are provided by the feeds the cows are consuming. The formulation of supplements to supply only what the animal needs may provide an opportunity for cost savings. This paper will describe the process …

Diabetes Alters Contraction-Induced Mitogen Activated Protein Kinase Activation In The Rat Soleus And Plantaris, Anjaiah Katta, Deborah L. Preston, Sunil K. Kakarla, Shinichi Asano, Sarath Meduru, Sriram P. Mupparaju, Ellie Yokochi, Kevin M. Rice, Devashish H. Desai, Eric R. Blough

MIIR Faculty Research

The prescription of anaerobic exercise has recently been advocated for the management of diabetes; however exercise-induced signaling in diabetic muscle remains largely unexplored. Evidence from exercise studies in nondiabetics suggests that the extracellular-signal-regulated kinases (Erk1/2), p38, and c-JUN NH2-terminal kinase (Jnk) mitogen-activated protein kinases (MAPKs) are important regulators of muscle adaptation. Here, we compare the basal and the in situ contraction-induced phosphorylation of Erk1/2- p38- and Jnk-MAPK and their downstream targets (p90rsk and MAPKAP-K2) in the plantaris and soleus muscles of normal and obese (fa/fa) Zucker rats. Compared to lean animals, the time course and magnitude of Erk1/2, p90rsk and …

Effects Of Sex, Age, And Season On Plasma Steroids In Free-Ranging Texas Horned Lizards (Phrynosoma Cornutum), Corina L. Wack, Stanley F. Fox, Eric C. Hellgren, Matthew P. Lovern

Publications

The Texas horned lizard (Phrynosoma cornutum) is protected in several states due to its apparently declining numbers; information on its physiology is therefore of interest from both comparative endocrine and applied perspectives. We collected blood samples from free-ranging P. cornutum in Oklahoma from April to September 2005, spanning their complete active period. We determined plasma concentrations of the steroids, progesterone (P), testosterone (T), and corticosterone (CORT) by radioimmunoassay following chromatographic separation and 17β-estradiol (E2) by direct radioimmunoassay. T concentrations in breeding males were significantly higher than in non-breeding males. P showed no significant seasonal variation within either sex. …

A New Species Of Giant Sengi Or Elephant-Shrew (Genus Rhynchocyon) Highlights The Exceptional Biodiversity Of The Udzungwa Mountains Of Tanzania, F Rovero, G B. Rathbun, A Perkin, T Jones, David O. Ribble, C Leonard, R R. Mwakisoma, N Doggart

Biology Faculty Research

A new species of sengi, or elephant-shrew, is described. It was discovered in the northern Udzungwa Mountains of Tanzania in 2005. Sengis (Order Macroscelidea, super-cohort Afrotheria) include four genera and 15 species of mammals that are endemic to Africa. This discovery is a significant contribution to the systematics of this small order. Based on 49 camera trap images, 40 sightings and five voucher specimens, the new sengi is diurnal and distinguished from the other three species of Rhynchocyon by a grizzled grey face, pale yellow to cream chest and chin, orange-rufous sides, maroon back and jet-black lower rump and thighs. …

Slow, Fast And In Between: Habitat Distribution And Behaviour Of Larvae In Nine Species Of Libellulid Dragonfly, Shannon J. Mccauley

Biological Sciences

1. Activity and microhabitat use are important factors determining species performance in habitats that differ in permanence and species composition of top predators. This study examined the relationship between the distribution across a gradient of habitat permanence and an associated transition in the composition of top predators and the behaviour of species of larval dragonflies. It also assessed the relationship between larval behaviour, body size and the duration of the larval stage. In laboratory mesocosms the mobility of the different species was measured, as was the extent to which they associated with artificial vegetation. 2. Species mobility was positively related …

Molecular Cloning And Sequence Analysis Of Multiple Cdna Variants For Thyroid-Stimulating Hormone Β Subunit (Tshβ) In The Fathead Minnow (Pimephales Promelas), Sean C. Lema, Jon T. Dickey, Penny Swanson

Biological Sciences

We cloned and sequenced full-length cDNAs encoding the β subunit of thyroid-stimulating hormone (TSHβ) from the pituitary of fathead minnow (Piephales promelas)using 5'-and 3'-rapid amplification of cDNA ends (RACE). Three cDNA variants for TSHβ with lengths of 1184-, 1093-, and 818-bp were identified. The cDNA variant of 1184-bp included 453-bp of open-reading frame and 610-bp of 3' UTR followed by a poly(A)site. This cDNA encodes 150 amino acids including a 19 residue signal peptide and a mature TSHβ protein of 131 residues with sequence identities of 97–53% to other fishes and 42–39% to mammals. The 1093-bp cDNA variant …

A Guide To The Common Native And Exotic Thistles Of South Dakota, Paul J. Johnson, Gary E. Larson, Darrell Deneke

SDSU Extension Special Series

This guide was compiled to provide an aid for the rapid identification of the more common pest and non-pest thistle species in South Dakota. Because of the great expense of managing and controlling invasive thistles in rangelands, pastures, and croplands, it is essential to be accurate in the identification of any species at hand. The recognition of native species not only helps maintain local biodiversity, but also prevents wasted effort, controls costs, and minimizes herbicide use and chemical pollution. It should be noted that native thistles are important both as floral resources for native pollinating insects and as seed sources …

Correlated Evolution Of Genome Size And Cell Volume In Diatoms (Bacillariophyceae), Jessica A. Connolly, Matthew J. Oliver, Jeremy M. Beaulieu, Charles A. Knight, Lars Tomanek, Mark A. Moline

Biological Sciences

A correlation between genome size and cell volume has been observed across diverse assemblages of eukaryotes. We examined this relationship in diatoms (Bacillariophyceae), a phylum in which cell volume is of critical ecological and biogeochemical importance. In addition to testing whether there is a predictive relationship across extant species, we tested whether evolutionary divergences in genome size were correlated with evolutionary divergences in cell size (using independent contrasts). We estimated total DNA content for 16 diatom species using a flow cytometer and estimated cell volumes using critical dimensions with scaling equations. Our independent contrast analyses indicated a significant correlated evolution …

The Qualitative Assessment Of Responsiveness To Environmental Challenge In Horses And Ponies, Fabio Napolitano, Giuseppe De Rosa, Ada Braghieri, Fernando Grasso, Aldo Bordi, Françoise Wemelsfelder

Sentience Collection

The responsiveness of 10 horses and 10 ponies to environmental challenge (represented by an open field test) was assessed using a qualitative approach based on free choice profiling methodology (FCP), which gives observers complete freedom to choose their own descriptive terms. Data were analysed with generalised Procrustes analysis (GPA), a multivariate statistical technique associated with FCP. A cross-validation of the outcomes of this approach to data recorded through quantitative behaviour analysis, and through a questionnaire given to the animals’ owner/riding instructor, was also performed using principal component analysis (PCA). Twelve undergraduate students generated their own descriptive vocabularies, by watching 20 …

Sub-Kilometer Length Scales In Coastal Waters, Shelley M. Blackwell, Mark A. Moline, Andrew Schaffner, Thomas Garrison, Grace Chang

Biological Sciences

Patchiness or spatial variability is ubiquitous in marine systems. With increasing anthropogenic impacts to coastal resources and coastal systems being disproportionately large contributors to ocean productivity, identifying the spatial scales of this patchiness, particularly in coastal waters, is of critical importance to understand coastal ecosystem dynamics. The current work focuses on fine scale structure in three coastal regions. More specifically, we utilize variogram analyses to identify sub-kilometer scales of variability in biological and physical parameters measured by an autonomous underwater vehicle (AUV) in the Mid-Atlantic Bight, Monterey Bay, and in San Luis Obispo Bay between 2001 and 2004. Critical scales …

Limitations Of Decomposition-Based Imaging Of Longitudinal Absorber Configurations, S D. Campbell, S D. Grobe, I L. Goodin, Q Su, Rainer Grobe

Faculty publications – Physics

We examine theoretically and experimentally an imaging scheme that uses the transverse intensity profile of the scattered light to reconstruct the locations of absorbers embedded in a turbid medium. This method is based on an a priori knowledge of the scattered light patterns associated with a single absorber that is located at various positions inside the medium. We discuss the range of validity of this method, and its sensitivity with regard to noise, and propose an algorithm to improve its accuracy.

Dynamics In The Transient Complex Of Plastocyanin-Cytochrome F From Prochlorothrix Hollandica, Rinske Hulsker, Maria Baranova, George S. Bullerjahn, Marcellus Ubbink

Biological Sciences Faculty Publications

The nature of transient protein complexes can range from a highly dynamic ensemble of orientations to a single well-defined state. This represents variation in the equilibrium between the encounter and final, functional state. The transient complex between plastocyanin (Pc) and cytochrome f (cyt of the cyanobacterium Prochlorothrix hollandica was characterized by NMR spectroscopy. Intermolecular pseudocontact shifts and chemical shift perturbations were used as restraints in docking calculations to determine the structure of the wild-type Pc-cytf complex. The orientation of Pc is similar to orientations found in Pc-cytf complexes from other sources. Electrostatics seems to play a modest role in complex …

A Seascape Approach To Predicting Reef Fish Distribution, Brian K. Walker

Oceanography Faculty Theses and Dissertations

Linking small-scale measurements of species distributions to broad-scale seascapes is necessary to understanding and predicting organismal distributions and their dynamics. This applies to reef fish populations as well. Reef fish studies are often limited to small spatial scales because of logistical and economic constraints; however, viewing the data at larger spatial scales might elucidate unforeseen relationships and patterns and facilitate regional management and conservation efforts. To address this growing need, an empirical model was created to predict reef fish abundance and species richness for the entire seascape using the relationship between the fish, benthic habitats, and GIS-derived topographic complexity metrics …

Three Friends Of Swiss-American Science: Louis Agassiz, Arnold Guyot, And Cornelius C. Felton, William A. Koelsch

Swiss American Historical Society Review

The year 2007 is a special one for those interested in Switzerland and in American science. It marks the bicentennial of the births of two Swiss scientists from Canton Neuchatel who came to America in the 1840s, the natural historian Jean Louis Rodophe Agassiz and the geographer-geologist Arnold Henri Guyot. It is also the bicentennial of the birth of the Harvard classicist Cornelius Conway Felton, who became Agassiz' closest American friend and his brother-in-law, and was the translator of Guyot' s first American lectures as well as the instigator of his first book. Agassiz was the eldest, born on 29 …

Ethnogenetic Layering (El): An Alternative To The Traditional Race Model In Human Variation And Health Disparity Studies, Fatimah Linda Collier Jackson

Department of Biology Faculty Publications

Traditionally, studies in human biodiversity, disease risk, and health disparities have defined populations in the context of typological racial models. However, such racial models are often imprecise generalizations that fail to capture important local patterns of human biodiversity.More explicit, detailed, and integrated information on relevant geographic, environmental, cultural, genetic, historical, and demographic variables are needed to understand local group expressions of disease inequities. This paper details the methods used in ethnogenetic layering (EL), a non-typological alternative to the current reliance of the biological racial paradigm in public health, epidemiology, and biomedicine.EL is focused on geographically identified microethnic groups or MEGs, …

Mutual Inhibition Between Kaposi’S Sarcoma-Associated Herpesvirus And Epstein-Barr Virus Lytic Replication Initiators In Dually-Infected Primary Effusion Lymphoma, Yanjun Jiang, Dongsheng Xu, Yong Zhao, Luwen Zhang

Nebraska Center for Virology: Faculty Publications

Background: Both Kaposi’s sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV) are members of the human gamma herpesvirus family: each is associated with various human cancers. The majority of AIDS-associated primary effusion lymphoma (PEL) are co-infected with both KSHV and EBV. Dually-infected PELs selectively switch from latency to lytic replication of either KSHV or EBV in response to chemical stimuli. KSHV replication and transcription activator (K-RTA) is necessary and sufficient for the switch from KSHV latency to lytic replication, while EBV BZLF1 gene product (EBV-Z) is a critical initiator for induction of EBV lytic replication.

Methodology/Principal Findings: We show K-RTA and …

Effects Of Climate Change On Energy Production And Use In The United States, Thomas Wilbanks, Vatsal Bhatt, Daniel Bilello, Stanley Bull, James Ekmann, William Horak, Y. Joe Huang, Mark D. Levine, Michael J. Sale, David Schmalzer, Michael J. Scott

United States Department of Energy: Publications

Climate change is expected to have noticeable effects in the United States: a rise in average temperatures in most regions, changes in precipitation amounts and seasonal patterns in many regions, changes in the intensity and pattern of extreme weather events, and sea level rise. Some of these effects have clear implications for energy production and use. For instance, average warming can be expected to increase energy requirements for cooling and reduce energy requirements for warming. Changes in precipitation could affect prospects for hydropower, positively or negatively. Increases in storm intensity could threaten further disruptions of the sorts experienced in 2005 …
