Interactions Among Western Ragweed And Other Sandhills Species After Drought, Patrick E. Reece, Joe E. Brummer, Brian K. Northup, Ann E. Koehler, Lowell E. Moser

Department of Agronomy and Horticulture: Faculty Publications

Interannual differences in yield and species composition of herbaceous vegetation on semiarid rangelands are common and often related to variations in precipitation regime. Interspecific interactions that occur after drought-induced population fluxes of western ragweed (Ambrosia psilostachya D.C.) were evaluated by removing western ragweed or associated species from 1-m² quadrats at weekly intervals beginning in early May, June, or July 1991 or 1992 on high-seral sandhills prairie in Nebraska. The composite of peak standing crops for ragweed and each group of associated species was 77% greater during May–October 1991 (2 252 kg•ha^-1) compared with 1992 (1 275 …

Maternal Anaemia And Its Impact On Perinatal Outcome In A Tertiary Care Hospital In Pakistan, F W. Lone, R N. Qureshi, F Emmanuel

Department of Obstetrics & Gynaecology

Maternal anaemia is a common problem in pregnancy, particularly in developing countries. We investigated the relationship between maternal anaemia and perinatal outcome in a cohort of 629 pregnant women from October 2001 to 2002. Of these, 313 were anaemic (haemoglobin < 11 g/L). Perinatal outcomes included preterm delivery, low birth weight, intrauterine growth retardation, perinatal death, low Apgar scores and intrauterine fetal death. Univariate and multivariate analyses were performed. The risk of preterm delivery and low birth weight among the anaemic women was 4 and 1.9 times more respectively than the non-anaemic women. The neonates of anaemic women also had 1.8 times increased risk having low Apgar scores at 1 minute and there was a 3.7 greater risk of intrauterine fetal death among the anaemic women than the non-anaemic women.

A Study Of Pediatric Heart Transplant Patients In Relationship To Post Transplant Coronary Artery Disease, Mark Randall

Loma Linda University Electronic Theses, Dissertations & Projects

Post transplant coronary artery disease influences short and long-term survival of pediatric heart transplant recipients. Associated cardiovascular disease risk factors among non-heart transplant adult and pediatric heart populations for development of coronary artery disease have been documented. Little is known about these typical cardiovascular disease risk factors as well as other possible risk factors in the development of post transplant coronary artery disease. Objective: The purpose of this research was to examine children/adolescents (n=194), 5-18 years old, at least one-year post heart transplant. This study also investigated if there were physiological and psychological/behavioral differences between recipients with (n = 28) …

Patterns Of Fitness And Fluctuating Asymmetry Across A Broad Hybrid Zone, Mitchell B. Cruzan

Biology Faculty Publications and Presentations

We estimated levels of developmental instability in leaves, as indicated by fluctuating asymmetry (i.e., random deviations from perfect bilateral symmetry), across a broad hybrid zone between two taxa in the Piriqueta caroliniana complex. Previous studies have indicated that this hybrid zone was initiated in southern Florida and has expanded northward. We found that plants from the hybrid zone generally had higher levels of leaf developmental instability than plants from allopatric regions, but the increase in asymmetry was not substantial. Although it is usually assumed that developmental instability is associated with lower fitness, these Piriqueta hybrids from central Florida are similar …

Estimating Survival Probabilities Of Unmarked Dependent Young When Detection Is Imperfect, Paul M. Lukacs, Victoria J. Dreitz, Kenneth P. Burnham, Fritz L. Knopf

Wildlife Biology Faculty Publications

We present a capture-recapture modeling approach to the estimation of survival probability of dependent chicks when only the attending adult bird is marked. The model requires that the bird's nest is found prior to hatching and that the number of eggs that hatch are counted. Subsequent data are sightings of the marked adult and a count of chicks with the adult. The model allows for imperfect detection of chicks, but the number of chicks can never exceed the number of eggs in the nest (i.e., adults cannot adopt chicks). We use data from radio-tagged adult Mountain Plovers (Charadrius montanus …

A Cross-Cultural Test Of Nancy Jay’S Theory About Women, Sacrificial Blood And Religious Participation, Virginia S. Fink

Journal of International Women's Studies

I examine the theoretical insights of Nancy Jay’s 1992 investigation of patrilineal sacrificial rituals and their role in the restriction of women in religious rituals. I use the Standard Cross-Cultural Sample, a representative sample of preindustrial societies, to test the strength of patrilineality and other factors identified as subordinating women in preindustrial societies. A societal pattern of male inheritance of property and patrilineal descent are the strongest predictors of women being restricted or excluded from major public religious rituals. The implications of this pattern for modern societies are discussed.

Sensory Hypoinnervation In Club Foot, M Ahmed, N Ahmed, K. M. Khan, Masood Umer, H. Rashid,, Pervaiz Hashmi

Department of Surgery Docs

Abstract

We have compared the density of nerve fibres in the synovium in club foot with that of specimens obtained from the synovium of the hip at operations for developmental dysplasia. The study focused on the sensory neuropeptides substance P; calcitonin gene-related peptide; protein gene product 9.5, a general marker for mature peripheral nerve fibres; and growth associated protein 43, a neuronal marker for new or regenerating nerve fibres. In order to establish whether there might be any inherent difference we analysed the density of calcitonin gene-related peptide-positive nerve fibres in the hip and ankle joints in young rats. Semi-quantitative …

Soil Microfungi In The Forest-Agricultural Landscape Of San Luis, Costa Rica, November 2004, Ellyn Yakowenko

Monteverde Institute: Tropical Ecology and Conservation

Soil microfungi are known to play key roles in ecosystem function and are often the first indicators of a breakdown in stability (Volk 2001). This study compares soil microfungal abundance and diversity across a tropical human land use gradient in the San Luis valley of Costa Rica. Microfungi were cultured from soil samples collected from primary forest, secondary forest, pasture, and coffee farm sites using the Soil Dilution Plate Technique (Christensen 2001). Thirty-six soil samples yielded a total of 17,321 isolates of 41 different morphological species. Each habitat type was characterized by the dominance of a few abundant species while …

Ithomiinae Visitation To A Source Of Pyrrolizidine Alkaloids (Ageratum Cf. Reedii) And Proximity To Mating Leks, November 2004, Katrina Welch

Monteverde Institute: Tropical Ecology and Conservation

Ithomiinae butterflies are protected from predation by pyrrolizidine alkaloids. These compounds are acquired as adults primarily from nectars, and, in the case of females from males via spermatophores. Nectar sources are most common outside of the forest, where Ithomiine collect in large aggregations, called leks, where mating occurs. In these leks males also use PA’s as precursors for mating pheromones. Visits to floral sources of protective compounds by Ithomiinae butterflies is 90-99% male (Drummond 1976). Three hypotheses explain this phenomenon. 1) females are constrained to obtain these pyrrolizidine alkaloids (PA’s) from males via spermatophores passed while mating, 2) females prefer …

Evidence For Floral Mimicry In Epidendrum Radicans (Orchidaceae) With Asclepias Curassavica (Apocynaceae) And Lantana Camara (Verbenaceae), November 2004, Sarah Dupre

Monteverde Institute: Tropical Ecology and Conservation

Floral mimicry may occur between plant species with geographic overlap, similar flowering times and a shared set of pollinators. To demonstrate mimicry in such species, visitors must enhance fitness of individual flowering plants. This study focuses on potential floral mimicry for a Neotropical roadside weed, Epidendrum radicans (Orchidaceae), which produces no nectar but resembles nectar-producing, sympatric and phenologically similar plant species, Asclepias curassavica (Apocynaceae) and Lantana camara (Verbenaceae). Twenty pollinia of E. radicans were placed in four different groups. One containing the orchid alone, the second consisting of the orchid and A. curassavica, the third consisting of the orchid and …

Epiphytic Lichen Communities On Ficus Spp. Microhabitats In Relation To Canopy Density, November 2004, Tom Mcfarland

Monteverde Institute: Tropical Ecology and Conservation

The purpose of this study was to determine if and how much forest canopy density affects the richness and composition of epiphytic lichen communities in Tropical Premontane Moist Forest. Lichen communities on the trunk and in the canopy on nine Ficus trees were examined. Friedman’s test was used to assess differences in lichen richness along a vertical gradient on trees, and Spearman rank test was used to look for a correlation between canopy density and lichen richness. Average habitat breadth between zones and between trees was also calculated. The results showed that there are significant differences in lichen richness across …

Changes In Avian Communities In The San Luis Valley, Costa Rica, November 2004, Nicholas Kovacs

Monteverde Institute: Tropical Ecology and Conservation

In this experiment, avifauna of the transformed Costa Rican premontane moist forest was censused using fixedradius point counts within three habitats. Species abundance for all observed birds was calculated based on these observations. Study sites included pasture and fragmented secondary forest. Species abundance was compared to previous values known for the area from a 1993 study. For the 51 species observed in the area, 31 showed frequency changes. Twenty-six of the 31 were negative declines, and five showed positive increases in population. Four species declined from common to rare, three species declined from fairly common to rare and two new …

Effects Of Coffee Agroecosystems On Moth Diversity In San Luis, Costa Rica, November 2004, Nathaniel Talbot

Monteverde Institute: Tropical Ecology and Conservation

The majority of Costa Rica’s primary forests have been fragmented and converted to agricultural landscape. Fragmentation studies based on Island Biogeography Theory and Hubble Unified Theory typically view the degraded area surrounding forests as uninhabitable, however, most agroecosystems actually serve as viable habitat to a subset of natural communities as well as a number of colonizing species. As a follow up to Rickets et al (2000) who studied moths in a tropical, agricultural landscape, this study focuses on how moth diversity is affected by coffee plantations in San Luis, Costa Rica. Moths were collected from three sites: a forest, a …

The 3-Hydroxy-3-Methylglutaryl Coenzyme-A (Hmg-Coa) Reductases, Jon A. Friesen, Victor W. Rodwell

Department of Biochemistry Faculty Publications

The enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase catalyzes the conversion of HMG-CoA to mevalonate, a four-electron oxidoreduction that is the rate-limiting step in the synthesis of cholesterol and other isoprenoids. The enzyme is found in eukaryotes and prokaryotes; and phylogenetic analysis has revealed two classes of HMG-CoA reductase, the Class I enzymes of eukaryotes and some archaea and the Class II enzymes of eubacteria and certain other archaea. Three-dimensional structures of the catalytic domain of HMG-CoA reductases from humans and from the bacterium Pseudomonas mevalonii, in conjunction with site-directed mutagenesis studies, have revealed details of the mechanism of catalysis. …

Fisheries Research Contract Report No. 10 - Mother-Of-Pearl Shell (Pinctada Maxima): Stock Evaluation For Management And Future Harvesting In Western Australia, Anthony M. Hart, Kim J. Friedman

Fisheries Research Contract Reports

The West Australian Pearling industry is one of Australia's most valuable aquaculture industries, currently generating around $120 - $160 million annually. The majority of pearl shell used to culture pearls come from the pearling beds in the inshore waters near Broome. The fishery for pearl oysters preferentially targets smaller (120mm - 165mm DVM) shell (hereafter defined as 'culture' shell), that are more suitable for culturing of pearls, leaving larger MOP oysters (175mm+) on the pearling grounds. These larger pearl oysters, the majority of which are female (protandric hermaphrodites), form a major component of the broodstock for the

fishery. Although MOP …

Measurements Of Fitness And Competition In Commensal Escherichia Coli And E. Coli O157:H7 Strains, Lisa M. Durso, David R. Smith, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

Although the main reservoirs for pathogenic Escherichia coli O157:H7 are cattle and the cattle environment, factors that affect its tenure in the bovine host and its survival outside humans and cattle have not been well studied. It is also not understood what physiological properties, if any, distinguish these pathogens from commensal counterparts that live as normal members of the human and bovine gastrointestinal tracts. To address these questions, individual and competitive fitness experiments, indirect antagonism assays, and antibiotic resistance and carbon utilization analyses were conducted using a strain set consisting of 122 commensal and pathogenic strains. The individual fitness experiments, …

Exergy Use In Bioenergetics, Yaşar Demirel

Papers in Analytical Chemistry

Every developed and adapted biological system extracts useful energy from outside, converts, stores it, and uses for muscular contraction, substrate transport, protein synthesis, and other energy utilizing processes. This energy management in a living cell is called the bioenergetics, and the useful energy is the exergy, which is destroyed in every irreversible process because of the entropy production. The converted exergy is the adenosine triphosphate (ATP) produced through the oxidative phosphorylation coupled to respiration in which the exergy originates from oxidation of reducing equivalents of nutrients. A living cell uses the ATP for all the energy demanding activities; it has …

Modeling The Tertiary Structure Of A Maize (Zea Mays Ssp. Mays) Non-Symbiotic Hemoglobin, Juán Sáenz-Rivera, Gautam Sarath, Raul Peter-Arredondo

Gautam Sarath Publications

The tertiary structure of a maize (Zea mays ssp. mays) non-symbiotic hemoglobin (Hbm) was modeled using computer tools and the known tertiary structure of rice Hb1 as a template. This method was tested by predicting the tertiary structure of soybean leghemoglobin a (Lba) using rice Hb1 as a template. The tertiary structures of the predicted and native Lba were similar, indicating that our computer methods could reliably predict the tertiary structures of plant Hbs. We next predicted the tertiary structure of Hbm. Hbm appears to have a long pre-helixA and a large CD-loop. The positions of the distal …
