The Influence Of Hurricane Winds On Caribbean Dry Forest Structure And Nutrient Pools, Skip Van Bloem, Ariel E. Lugo, Rebecca Ostertag, Maria Rivera Costa, Ivelisse Ruiz Bernard, Sandra Molina Colón, Miguel Canals Mora

Publications

In 1998, we measured the effects of Hurricane Georges after it passed over long‐term research sites in Puerto Rican dry forest. Our primary objectives were to quantify hurricane effects on forest structure, to compare effects in a large tract of forest versus a series of nearby forest fragments, to evaluate short‐term response to hurricane disturbance in terms of mortality and sprouting, and to assess the ability of hurricanes to maintain forest structure. We sampled damage from 33 plots (1.3 ha) across a 3000‐ha tract of forest as well as in 19 fragments. For stems with 2.5‐cm minimum diameter, 1004 stems/ha …


Larvae Of Ceratocanthidae And Hybosoridae (Coleoptera: Scarabaeoidea): Study Of Morphology, Phylogenetic Analysis And Evidence Of Paraphyly Of Hybosoridae, Vasily V. Grebennikov, Alberto Ballerio, Federico C. Ocampo, Clarke E. Scholtz Oct 2004

Larvae Of Ceratocanthidae And Hybosoridae (Coleoptera: Scarabaeoidea): Study Of Morphology, Phylogenetic Analysis And Evidence Of Paraphyly Of Hybosoridae, Vasily V. Grebennikov, Alberto Ballerio, Federico C. Ocampo, Clarke E. Scholtz

University of Nebraska State Museum: Entomology Papers

Larvae of the scarabaeoid genera Germarostes Paulian, Cyphopisthes Gestro, Paulianostes Ballerio, Ceratocanthus White, Pterorthochaetes Gestro, Madrasostes Paulian, Astaenomoechus Martínez & Pereira (Ceratocanthidae) and Hybosorus Macleay, Phaeochrous Castelnau, and Anaides Westwood (Hybosoridae) are described, keyed and illustrated with fifty-seven drawings. A phylogenetic analysis of these two families based on larval morphology is presented. Fifty-four larval morphological and three biological characters from twenty-seven taxa revealed nineteen equally parsimonious cladograms. The monophyly of (Ceratocanthidae + Hybosoridae) is supported by four unambiguous unique synapomorphies: dorsal medial endocarina on cranium extended anteriorly into frontal sclerite; presence of large membranous spot on apical antennomere; labium dorsally …

An exchange regarding the article: Bradley, K. L., E. I. Damschen, L. M. Young, D. Kuefler, S. Went, G. Wray, N. M. Haddad, J. M. H. Knops, and S. M. Louda. 2003. Spatial heterogeneity, not visitation bias, dominates variation in herbivory. Ecology 84:2214–2221.

Cahill et al. write:
Here we show that the experimental design and statistical analysis used by Bradley et al. (2003) do not adequately control for Type II experimental error (accepting the null hypothesis when it is in fact false). This is particularly important when responses have low effect sizes such as those previously demonstrated for visitation effects …


Observations On Myiasis By The Calliphorids, Bufolucilia Silvarum And Bufolucilia Elongata, In Wood Frogs, Rana Sylvatica, From Southeastern Wisconsin, Matthew G. Bolek, John J. Janovy Jr. Oct 2004

Observations On Myiasis By The Calliphorids, Bufolucilia Silvarum And Bufolucilia Elongata, In Wood Frogs, Rana Sylvatica, From Southeastern Wisconsin, Matthew G. Bolek, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Larvae of certain species of blowflies (Calliphoridae) can cause myiasis in frogs and toads, but there are few reports from North American amphibians. Of these, most are from toads (bufonids). In this study, we observe primary myiasis in a population of juvenile wood frogs, Rana sylvatica, collected on August 22-23, 2003, from southeastern Wisconsin and compare our observations with previous studies on myiasis from toads. Two (5%) of 39 frogs were infected by the blow fly Bufolucilia silvarum, with an intensity of 28 and 31, whereas 1 (2.5%) of 39 frogs was infected by the blow fly Bufolucilia …

Detection And Quantitation Of Bovine Respiratory Syncytial Virus Using Real-Time Quantitative Rt-Pcr And Quantitative Competitive Rt-Pcr Assays, Jenna Achenbaum, Christina L. Topliff, Ventzislav B. Vassilev, Ruben O. Donis, Kent M. Eskridge, Clayton L. Kelling Oct 2004

Detection And Quantitation Of Bovine Respiratory Syncytial Virus Using Real-Time Quantitative Rt-Pcr And Quantitative Competitive Rt-Pcr Assays, Jenna Achenbaum, Christina L. Topliff, Ventzislav B. Vassilev, Ruben O. Donis, Kent M. Eskridge, Clayton L. Kelling

Nebraska Center for Virology: Faculty Publications

A single tube, fluorogenic probe-based, real-time quantitative reverse transcription-polymerase chain reaction (Q-RT-PCR) assay was developed for detection and quantitation of bovine respiratory syncytial virus (BRSV) using BioRad’s iCycler iQ™. Real-time Q-RT-PCR was compared with quantitative competitive RT-PCR (QC-RT-PCR) and viral titers. Viral mRNA levels were measured in BRSV-infected bovine turbinate cell lysate harvested at eight time points (1.5, 6, 12, 24, 36, 48, 60, 72 h) post-infection. A homologous BRSV cRNA standard was used for quantitation of the mRNA by plotting a standard curve of cycle threshold (Ct) values versus standard 10-fold dilutions of cRNA of known concentrations. Detection as …

Cd8+ T Cells Responding To Influenza Infection Reach And Persist At Higher Numbers Than Cd4+ T Cells Independently Of Precursor Frequency, Timothy J. Powell, Deborah M. Brown, Joseph A. Hollenbaugh, Tina Charbonneau, Roslyn A. Kemp, Susan L. Swain, Richard Dutton

Nebraska Center for Virology: Faculty Publications

The activation, localization, phenotypic changes, and function of CFSE-labeled naive influenza-specific CD8+ and CD4+ T cells following influenza infection were examined. Response of adoptively transferred CD8+ T cells was seen earliest in draining lymph node. Highly activated cells were found later in the lung, airways, and spleen, were cytolytic, and expressed IFN-γ upon restimulation. Similar amounts of division at early time points, but higher numbers of CD8+ T cells, were detected at 9 and 30 days postinfection after cotransfer of CD4+ and CD8+ T cells followed by infection. Transfer of much smaller numbers of …


Nest-Building And Spawning Behaviors In Nocomis Effusus (Actinopterygii: Cyprindae), Eugene G. Maurakis, George E. Maurakis Oct 2004

Nest-Building And Spawning Behaviors In Nocomis Effusus (Actinopterygii: Cyprindae), Eugene G. Maurakis, George E. Maurakis

Virginia Journal of Science

Spawning behavior in Nocomis effusus is described from direct observations and review of videotapes made in Yellow Creek (Cumberland River drainage), Tennessee in 2003. Nest construction (i.e., excavating a concavity, forming a platform, and building a mound), and spawning behavior in N. effusus where a single breeding male excavates a pit and spawns with females on the upstream slope of his nest is like that described for Nocomis asper and Nocomis biguttatus. In digging a spawning pit, a male N. effusus reshapes and reorganizes substrate materials that results in spawning areas on the upstream slope of the nest composed …


Growth Of Stygobitic (Orconectes Australis Packardi) And Epigean (Orconectes Cristavarius) Crayfishes Maintained In Laboratory Conditions, Ann-Simone Cooper, Robin L. Cooper Oct 2004

Growth Of Stygobitic (Orconectes Australis Packardi) And Epigean (Orconectes Cristavarius) Crayfishes Maintained In Laboratory Conditions, Ann-Simone Cooper, Robin L. Cooper

Biology Faculty Publications

This study reports on maintenance and growth of the cave crayfish, Orconectes australis packardi, and the epigean crayfish, Orconectes cristavarius, with laboratory conditions for 1 and 2 years. The O. a. packardi survived well compared to the O. cristavarius in captivity. The poor survival of the epigean species was probably due to unsuitable conditions. The epigean as well as the cave crayfish molted and grew in captivity, but without any significant difference in molt frequency between species. In the first year, total body length was obtained to assay growth, whereas in the second year the more accurate measure …

The Florida Bonneted Bat, Eumops Floridanus (Chiroptera: Molossidae): Distribution, Morphometrics, Systematics, And Ecology, Robert M. Timm, Hugh H. Genoways Oct 2004

The Florida Bonneted Bat, Eumops Floridanus (Chiroptera: Molossidae): Distribution, Morphometrics, Systematics, And Ecology, Robert M. Timm, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

A review and reappraisal of bats of the genus Eumops (Chiroptera: Molossidae) reveals that considerable geographic variation is present in the bonneted bat, E. glaucinus; it is a complex consisting of >1 species. Bonneted bats in Florida are significantly larger than those in all other populations, and have proportionally shorter and deeper basisphenoid pits, the glenoid fossa is broadly triangular with rounded apices, and bacular shape differs from that in other populations. Additionally, bonneted bats in Florida have a broader palate than bats from populations in South America. Given these differences, the correct name for both Pleistocene and Recent …

A Brief Note On The Authorship Of The First Flora Virginica: Clayton, Gronovius, And Linnaeus, Joan K. Stemmler Oct 2004

A Brief Note On The Authorship Of The First Flora Virginica: Clayton, Gronovius, And Linnaeus, Joan K. Stemmler

Virginia Journal of Science

A modern Flora of Virginia will soon be published, providing an occasion to remember the publication of the first Flora Virginica in the 18th century and to establish the proper attribution of its authorship. Based on a manuscript by John Clayton, Flora Virginica was published in two parts in 1739 and 1743 by the Dutchman Johan Frederick Gronovius. Although both names are printed on the title page, the book is often cited with Gronovius listed as the author. This tradition, interpreted in modern understandings of plagiarism, has led to an assertion that Gronovius misrepresented Clayton's work as his own. This …

Asymmetric Atp Binding And Hydrolysis Activity Of The Thermus Aquaticus Muts Dimer Is Key To Modulation Of Its Interactions With Mismatched Dna, Edwin Antony, Manju M. Hingorani Oct 2004

Asymmetric Atp Binding And Hydrolysis Activity Of The Thermus Aquaticus Muts Dimer Is Key To Modulation Of Its Interactions With Mismatched Dna, Edwin Antony, Manju M. Hingorani

Biological Sciences Faculty Research and Publications

Prokaryotic MutS and eukaryotic Msh proteins recognize base pair mismatches and insertions or deletions in DNA and initiate mismatch repair. These proteins function as dimers (and perhaps higher order oligomers) and possess an ATPase activity that is essential for DNA repair. Previous studies of Escherichia coli MutS and eukaryotic Msh2−Msh6 proteins have revealed asymmetry within the dimer with respect to both DNA binding and ATPase activities. We have found the Thermus aquaticus MutS protein amenable to detailed investigation of the nature and role of this asymmetry. Here, we show that (a) in a MutS dimer one subunit (S1) binds nucleotide …

Novel Weapons: Invasive Success And The Evolution Of Increased Competitive Ability, Ragan M. Callaway, Wendy M. Ridenour Oct 2004

Novel Weapons: Invasive Success And The Evolution Of Increased Competitive Ability, Ragan M. Callaway, Wendy M. Ridenour

Biological Sciences Faculty Publications

When introduced to new habitats by humans, some plant species become much more dominant. This is primarily attributed to escape from specialist consumers. Release from these specialist enemies is also thought by some to lead to the evolution of increased competitive ability, driven by a decrease in the plant's resource allocation to consumer defense and an increase in allocation to size or fecundity. Here, we discuss a new theory for invasive success – the “novel weapons hypothesis”. We propose that some invaders transform because they possess novel biochemical weapons that function as unusually powerful allelopathic agents, or as mediators of …

On Thacker's Biomedia (2004), Nicholas Ruiz Iii

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Only we could have done it. The Code (DNA and its analogs, etc.) that we perhaps only narrate, never forgetting all of the fictions that narration portends, today consciously edits the text that evolution has edited unconsciously for eons. Thacker considers how humans -- perhaps little more than interactive Code, manipulate the Code -- with the technology of the Code. No other faction of Code has yet to make such heady ‘gains.’ Where posthumanity was always a literary endeavor, a literary bypass, out of instrumental science and into fictive states, it now is a technical endeavor, encompassing a …
