Life History And Status Classifications Of Birds Breeding In Iowa, Louis B. Best, Kathryn E. Freemark, Barbara S. Steiner, Timothy M. Bergin

Journal of the Iowa Academy of Science: JIAS

Life history and status classifications were compiled for 145 bird species that breed in Iowa. Species were classified by food type and substrate, nest substrate, susceptibility to cowbird parasitism, migratory status, predominant habitat use and habitat-use specialization, body mass (an index of home range/territory size), area sensitivity, population trend and vulnerability, and beneficial/harmful aspects in relation to agriculture. Such information may be used to make interspecific comparisons, evaluate interrelationships among life history and status characteristics, and provide insights into the interpretation of previous research. This synthesis also can aid those responsible for making conservation and management decisions about Iowa's avifauna.

The Natural History Of Aconitum Noveboracense Gray (Northern Monkshood), A Federally Threatened Species, Margaret A. Kuchenreuther

Journal of the Iowa Academy of Science: JIAS

Aconitum noveboracense Gray (Ranunculaceae), commonly known as northern monkshood, is a federally threatened herbaceous perennial that occurs in disjunct populations in Iowa, Wisconsin, Ohio and New York. It appears to be a glacial relict, existing today only in unique areas with cool, moist microenvironments, such as algific talus slopes. Field studies reveal that A. noveboracense has a complex life history. Perennation of individual plants occurs through the annual production of daughter tubers. Vegetative reproduction is commonly observed, and can occur by means of aerial and subterranean bulbils, as well as by development of adventitious root buds. Populations also reproduce sexually …

Fire-Bgc--A Mechanistic Ecological Process Model For Simulating Fire Succession On Coniferous Forest Landscapes Of The Northern Rocky Mountains, Robert E. Keane, Penelope Morgan, Steven W. Running

Aspen Bibliography

An ecological process model of vegetation dynamics mechanistically simulates long-term stand dynamics on coniferous landscapes of the Northern Rocky Mountains. This model is used to investigate and evaluate cumulative effects of various fire regimes, including prescribed burning and fire exclusion, on the vegetation and fuel complex of a simulation landscape composed of many stands. Detailed documentation of the model FIRE-BGC (a FIRE BioGeoChemical succession model) with complete discussion of all model parameters is followed with results of an application of the FIRE-BGC to a whitebark pine landscape in the Bob Marshall Wilderness Complex. Simulation results of several management scenarios are …

Waste-Wood-Derived Fillers For Plastics, Brent English, Craig M. Clemons, Nicole Stark, James P. Schneider

Aspen Bibliography

Filled thermoplastic composites are stiffer, stronger, and more dimensionally stable than their unfilled counterparts. Such thermoplastics are usually provided to the end-user as a precompounded, pelletized feedstock. Typical reinforcing fillers are inorganic materials like talc or fiberglass, but materials derived from waste wood, such as wood flour and recycled paper fiber, are also effective as fillers. The goal of this project was to generate commercial interest in using waste-wood–paper-derived fillers (WPFs) to reinforce thermoplastics. The research strategy was twofold: developmental research and outreach. Specific objectives were (1) to improve wastepaper fiber preparation, feeding, and compounding methods, and optimize composite performance, …

Captive Environmental Influences On Behavior In Zoo Drills And Mandrills (Mandrillus), A Threatened Genus Of Primate, Erik Terdal

Dissertations and Theses

Drills (Mandrillus leucophaeus) are an endangered species of African monkey (Cercopithecidae), and their sole congener the mandrill (Mandrillus sphinx) is vulnerable to extinction. Both species are threatened in the wild by deforestation and hunting.

Drills have a poor record of captive reproduction. Many individuals appear to have behavioral deficiencies which interfere with reproduction. Thus, the zoo population of drills does not serve as a “hedge” against the species’ total extinction: drills are endangered in captivity as well as in the wild. Mandrills, by contrast, reproduce well in captivity. Information on the behavior of mandrills in captivity may help zoo managers …

Sperm Competition And Sex Allocation In Simultaneous Hermaphrodites, Eric Charnov

Biology Faculty & Staff Publications

Sex allocation theory is developed for hermaphrodites having frequent copulations and long-term sperm storage. Provided the sperm displacement mechanisms are similar to those known in insects, the ESS allocation to sperm versus eggs satisfies a rather simple rule. There are no data to test this rule, as yet.

Use Of Expected Progeny Differences For Marbling In Beef: I. Production Traits, B. A. Vieselmeyer, Richard J. Rasby, B. L. Gwartney, Chris R. Calkins, Rick Stock, James A. Gosey

Department of Animal Science: Faculty Publications

Six Angus bulls with HIGH (>.4) and six bulls with LOW (<-.16) expected progeny differences (EPD) for marbling were used to evaluate the impact of marbling on progeny production and carcass traits. Bulls were randomly bred to MARC II (¼ Hereford, ¼ Simmental, ¼ Angus, ¼ Gelbvieh) composite cows in each of 2 yr to calve in the spring. At weaning, steers and heifers were separated and managed in different production systems. Steers (n = 131) were fed a growing diet (1.1 Mcal of NE_g/kg) for 48 d followed by adaptation to a 93% concentrate finishing diet. Heifers (n = 125) were fed a growing diet (.79 Mcal of NE_g/kg) for 191 d followed by adaptation to the same 93% concentrate diet. Steers and heifers from each treatment were slaughtered at two times spaced about 60 d apart within both years. Marbling EPD class had no effect on fat thickness, USDA yield grade, carcass weight, finishing daily gain, finishing DMI, or finishing efficiency ( P > .18). More ( …

Use Of Expected Progeny Differences For Marbling In Beef: Ii. Carcass And Palatability Traits, B. L. Gwartney, Chris R. Calkins, Richard J. Rasby, Rick Stock, B. A. Vieselmeyer, James A. Gosey

Department of Animal Science: Faculty Publications

A 2-yr study was conducted to determine the effect of EPD for marbling on marbling score, palatability traits, and carcass fatness in beef. Steer (n = 122) and heifer (n = 123) carcasses were obtained by mating Angus bulls having a high (>.4) or low (<-.16) EPD for marbling to MARC II cows (¼ Angus, ¼ Hereford, ¼ Simmental, and ¼ Gelbvieh). Carcass traits, composition of primals, quarters, and sides, palatability, and shear force data were obtained and adjusted to the mean number of days on feed, equal marbling score (Small⁵⁰) , fat thickness (1.0 cm), and carcass weight (318 kg) end points. Steer carcasses from the high marbling EPD group, adjusted to the mean number of days on feed, had significantly more marbling ( P < .01) and less subcutaneous fat in the side and the hindquarter ( P < .10) than their low marbling EPD counterparts. Adjusting steers to Small50 marbling produced smaller longissimus muscle area (by 5 cm²) , less fat thickness (1.15 vs 1.28 cm), and lighter side weights (306 vs …

Changing Dose Of Progesterone Results In Sudden Changes In Frequency Of Luteinizing Hormone Pulses And Secretion Of 17Β-Estradiol In Bovine Females, E. G. M. Bergfeld, F. N. Kojima, Andrea S. Cupp, M. E. Wehrman, K. E. Peters, V. Mariscal, T. Sanchez, J. E. Kinder

Department of Animal Science: Faculty Publications

The aim of the present study was to elucidate the time course according to which changes in circulating concentrations of progesterone influence pulsatile secretion of LH and secretion of 17β-estradiol. Our working hypothesis was that changing the dose of progesterone would result in changes in frequency of LH pulses and secretion of 17β-estradiol within 72 h. Five days after behavioral estrus, thirty-three cows were randomly assigned to one of five groups: 1) control, no treatment (CONT, n = 5); 2) treatment with two progesterone-releasing intravaginal devices (PRIDs) for 11 days (2PRID, 5-6 ng/ml plasma progesterone, n = 7); 3) treatment …
