ZooKeys , 2013, DOI: 10.3897/zookeys.260.3971
Abstract: During May 2009 and July 2011, we collected 357 mammals and examined each for ectoparasites. Among the ectoparasites collected, a new species of flea was discovered. This new species, Lentistivalius philippinensis, is described from the male sex only. Two males were recovered from two specimens of the soricid Crocidura grayi Dobson in Municipality Maria Aurora, Aurora Province, Luzon, Philippines. Additional fleas included Thaumapsylla breviceps orientalis Smit, Thaumapsylla longiforceps Traub, and Ischnopsyllus indicus Jordan. Although the latter species is common in Japan and documented in Guam (as well as mainland Southeast Asia) also on Pipistrellus javanicus (Gray), I. indicus represents a new record in the Philippine Islands. The ascodipterinae (Streblidae) Maabella stomalata and Ascodipteron speiserianum Muir collected from Rhinolophus inops K. Andersen and Rhinolophus subrufus K. Andersen, respectively, also represent new host records. A key to the species of the flea genus Lentistivalius Traub is provided.
Evolution of Novel Signal Traits in the Absence of Female Preferences in Neoconocephalus Katydids (Orthoptera, Tettigoniidae)
Sarah L. Bush,Johannes Schul
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0012457
Abstract: Communication signals that function to bring together the sexes are important for maintaining reproductive isolation in many taxa. Changes in male calls are often attributed to sexual selection, in which female preferences initiate signal divergence. Natural selection can also influence signal traits if calls attract predators or parasitoids, or if calling is energetically costly. Neutral evolution is often neglected in the context of acoustic communication.
Studying the Ecological Benefits of Spartina Grass Species and Use of a Mathematical Model (Pick’s Theorem) for Historical Documentation and Future Restoration of Hypoxic Marshlands  [PDF]

Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.716110
Abstract: Coastal erosion, subsidence, salt water intrusion, and hypoxia are forces that impact Louisiana and beyond. The objective of this research was to determine the extent of land loss due to erosion and establish the best Spartina (S.) species to ameliorate the coast. Using graph theory in the Geometer’s Sketch Pad program, progressive land loss from Isles Dernieres was determined from 1853 to 2005. This was accomplished using Pick’s Theorem (A = I + B/2 - 1), where A = total land area, I = interior intersections, and B = boundary intersections. The analysis indicated that there had been more than ninety percent land loss from 1853 to 2005. Additionally, four plants from each Spartina species (alterniflora, patens, and spartinae) were planted and flooded in four containers, respectively, filled with potting soil, and a non-vegetated control was included in this same manner. Dissolved oxygen was measured three times a week under three different temperature regimes, twenty-two, thirty, and ten degrees Celsius, respectively. This resulted in the control group diffusing the most oxygen at twenty-two degrees Celsius, the S. alterniflora diffusing the most oxygen at thirty degrees Celsius, and all the species diffusing statistically similar oxygen levels at ten degrees Celsius. After six months of flooded conditions, penetration and subsidence were measured. The vegetated soils required the greatest penetration forces and subsided the least. Oxygen diffusion is dependent on plant species and temperature. The penetration and subsidence results also support the conclusion that plants can reduce land loss and preserve the coastline.
Ecological Restoration Zones within the Monkey River Area (Belize) Using Community Grown Nurseries to Produce Plants for Riparian Strips  [PDF]
Anna Koonce, Edward Bush
Journal of Environmental Protection (JEP) , 2019, DOI: 10.4236/jep.2019.103020
Abstract: Agricultural runoff near watersheds causes severe pollution of estuaries that can cause severe detrimental effects. The purpose of this experiment is to determine the most effective riparian strip combination to reduce offsite runoff and pollution. Three combinations of riparian strips were tested by simulating runoff in a greenhouse environment with drip irrigation. Results of elements in leaf tissues, effluent volume, and effluent element concentrations showed that the riparian strips with a combination of grass and trees was the most successful. If the detailed plan provided by this experiment for growing and planting a riparian strip near Monkey River is installed, then it can be concluded that the riparian strip will reduce nutrient runoff and help prevent erosion.
Bench-to-bedside review: The role of β-lactamases in antibiotic-resistant Gram-negative infections

Critical Care , 2010, DOI: 10.1186/cc8892
Abstract: Much has been publicized recently about the expansion of hospital- and community-based infections caused by Gram-positive bacteria, especially those caused by vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA) [1]. However, a second, but potentially more important, threat to critical care is that caused by the multidrug-resistant Gram-negative bacteria. The response of the pharmaceutical companies over the past decade has been to design new drugs that can treat VRE and both hospital- and community-acquired MRSA infections [2]. However, what is lacking from the current pharmaceutical arsenal are drugs to treat multidrug-resistant Gram-negative infections in the hospital setting [3]. Because β-lactam antibiotics have long been a component in the treatment regimen for serious nosocomial infections, any threat to their efficacy must be examined closely.Among the β-lactam antibiotics of clinical utility for the treatment of infections caused by susceptible Gram-negative bacteria are penicillins such as amoxicillin, oral cephalosporins such as cefpodoxime and cefuroxime axetil, parenteral cephalosporins such as cefepime and ceftriaxone, and the carbapenems such as doripenem, ertapenem, imipenem, and meropenem. Combinations of penicillins with β-lactamase inhibitors also play prominent therapeutic roles, with amoxicillin-clavulanic acid being a major factor in the treatment of community infections and piperacillin-tazobactam being important for serious hospital-acquired infections. In this review, the role of β-lactamases will be discussed as a major cause of resistance to these safe and widely prescribed drugs.Infections caused by Gram-positive bacteria represented the majority of serious infections prior to the late 1950 s. Thus, it is not surprising that the increased use of penicillins to treat the associated diseases caused β-lactam resistance to arise in the clinical setting, first in the staphylococci and then in Gram-negat

La centralidad de la cultura del traductor: la Celestina de Fernando de Rojas y la creación del estilo en traducción = The Centrality of a Translator’s Culture: Fernando de Rojas’s Celestina and the Creation of Style in Translation

1611 : Revista de Historia de la Traducción , 2010,
Abstract: Este artículo analiza el modo en que la cultura del traductor (clase social, educación, período histórico, experiencia académica y traductora) incide sobre las estrategias que afectan a una nueva versión inglesa de la Celestina y el modo en que el traductor crea el que considera que es el nuevo estilo necesario para emular la conmoción de lo nuevo lograda por el converso Fernando de Rojas frente a la tradición traductora basada en la imitación de un lenguaje pseudoisabelino. Se hacen comparaciones con otras traducciones históricas y contemporáneas, y se detalla el proceso de reescritura de un pasaje concreto. El traductor describe su concepción de la obra como primera novela europea (1500) en lugar de como obra teatral defectuosa , así como sus decisiones interpretativas para resaltar la originalísima igualdad de retórica que culmina en la caracterización de la alcahueta y sus amigas. El pasaje seleccionado esboza el gusto de Celestina por el juego léxico y la energía intelectual que despliega en sus actividades como alcahueta. Dicho análisis desafía las limitaciones de la investigación basada en el análisis de corpus aplicado a la traducción. An analysis of how the culture of the translator - social class, education, historical period, experience of scholarship and translation - impacts on strategies for a new translation of La Celestina and of how the translator creates what he believes to be the necessary style to emulate converso Fernando de Rojas's "shock of the new" against the tradition of fashioning a pseudo-Elizabethan language. Comparisons are made with historic and contemporary re-translations and the drafting process of a particular passage is detailed. The translator describes his framing of the work as the first European novel (1500) rather than a "flawed" drama and the interpretive moves within his translation to highlight de Rojas's most original "equality of rhetoric" which climaxes in the characterisation of the procuress and her female friends. The selected passage delineates Celestina's appetite for verbal play and the intellectual energy deploys in her scurrilous activities. The analysis challenges the narrowness of corpus research on translating styles.
Selective Constraint on Noncoding Regions of Hominid Genomes.
Bush,Lahn
PLOS Computational Biology , 2005,
Abstract: An important challenge for human evolutionary biology is to understand the genetic basis of human-chimpanzee differences. One influential idea holds that such differences depend, to a large extent, on adaptive changes in gene expression. An important step in assessing this hypothesis involves gaining a better understanding of selective constraint on noncoding regions of hominid genomes. In noncoding sequence, functional elements are frequently small and can be separated by large nonfunctional regions. For this reason, constraint in hominid genomes is likely to be patchy. Here we use conservation in more distantly related mammals and amniotes as a way of identifying small sequence windows that are likely to be functional. We find that putatively functional noncoding elements defined in this manner are subject to significant selective constraint in hominids.
