Plastic Visual Barriers Were Ineffective At Reducing Recolonization Rates Of Prairie Dogs, Scott E. Hygnstrom

Great Plains Wildlife Damage Control Workshop Proceedings

Two plastic visual barriers were ineffective in controlling expansion of 7 active black-tailed prairie dog (Cynomys ludovicianus) colonies and recolonization of 7 toxicant-treated sections of colonies. Barriers constructed with Sno-Strap, a 15.2- cm wide band of high-tensile polyethylene plastic, were destroyed by wind action within 3 weeks. Barriers constructed with Tensar® snowfence cost $2.10/m and retained their structural integrity for 3 years with occasional maintenance. Recommendations are provided to increase effectiveness of visual barriers.

Effectiveness Of Squirrel Fencing For Protecting Pecan Groves, Mcalister D. Maxwell, J. Grant Huggins, Clark E. Adams

Great Plains Wildlife Damage Control Workshop Proceedings

During 1994, we tested the hypothesis that an energized, high-tensile wire fence prevents fox squirrels (Sciurus niger) from crossing into a pecan (Carya illinoensis) grove. When the fence was energized, we recorded fewer (P = 0.03) trips across the fence by squirrels (n - 19) and fewer (P < 0.001) telemetry fix-points in the pecan grove. Effective squirrel fencing may offer wildlife managers an alternative method of damage prevention. Ecological ramifications to target and non-target species are discussed.

Depredation Of Catfish By Double-Crested Cormorants At Aquaculture Facilities In Oklahoma, Robert L. Simmonds Jr., Alexander V. Zale, David M. Leslie Jr.

Great Plains Wildlife Damage Control Workshop Proceedings

Oklahoma has about 324 ha of surface water in catfish (Ictalurus spp.) production. The state also supports a large number of migrating and wintering piscivorous birds, particularly double-crested cormorants (Phalacrocorax auritus). To address concerns of aquaculture facility operators regarding loss of fish to cormorants, we asked 11 operators to conduct regular counts of piscivorous birds at each facility. These data were used to determine factors affecting cormorant density at facilities and to estimate amount of catfish lost to cormorant depredation. Cormorant density (birds/ha/day) was positively correlated with surface area of water in production at facilities <10 ha (r = …

Feral Hogs In The Rolling Plains Of Texas: Perspectives, Problems, And Potential, Douglas R. Tolleson, William E. Pinchak, Dale Rollins, Leland J. Hunt

Great Plains Wildlife Damage Control Workshop Proceedings

Feral hogs (Sus scrofa) have expanded their territory in Texas and are now found in all but the extreme western portions of the state. Perhaps the most dramatic expansion has occurred in the Rolling Plains of northwest Texas. Perspectives on feral hogs range from definitely for to adamantly against. Problems encountered with feral hogs include: (1) damage to crops and livestock, or facilities and equipment, (2) transmission of disease to humans and livestock, or (3) interaction with native wildlife including competition for available resources, depredation and destruction of habitat. The feral hog is also an animal with economic …

Immunocontraception And Possible Application In Wildlife Damage Management, Lowell A. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

lmmunocontraception technology appears to have viable application in wildlife damage management. However, administration of these vaccines is presently performed by syringe injection or remote delivery by darts or bio-bullets. In order for immunocontraception to be successful for broad scale application to free-roaming animals, the vaccine must be delivered in an oral form. Recent advances in molecular biology, immunology, and pathology of mucosal infection gives us tools to develop effective oral vaccines. Oral immunocontraceptive vaccine encapsulated in adhesive liposomes or non-virulent live vectors holds promise as a practical approach for immunocontraception of free-roaming wildlife. Issues of safety, species specificity, regulatory constraints, …

Primase Structure And Function, Mark A. Griep

Department of Chemistry: Faculty Publications

Primase is the ssDNA-dependent RNA polymerase that synthesizes RNA primers during DNA replication. In common with all DNA and RNA polymerases, primase has structural and functional features involved in polymer elongation. As RNA polymerase, it has structural and functional features for initiating chain synthesis. As a primase, it has structural and functional features for initiating chain synthesis on ssDNA. Using amino acid sequence analysis the structure of Escherichia coli primase responsible for binding zinc, at least three magnesium, and DnaB helicase has been identified. One of the magnesium binding motifs resembles the “active magnesium” motif found in all DNA and …

Movement Of Dna Across The Chloroplast Envelope: Implications For The Transfer Of Promiscuous Dna, Heriberto D. Cerutti, André Jagendorf

Center for Plant Science Innovation: Faculty Publications

Little is known about the mechanistic basis for the movement of promiscuous nucleic acids across cell membranes. To address this problem we sought conditions that would permit the entry of plasmid DNA into isolated, intact pea chloroplasts. DNA uptake did not occur normally, but was induced by hypotonic treatments, by incubation with millimolar levels of Mg²⁺, or by heat shock at 42 °C. These results are consistent with DNA movement being permitted by conditions that transiently alter the permeability of the chloroplast envelope. Plant cells are subject to osmotic tensions and/or conditions inducing polymorphic changes in the membranes, …

Role Of Specific Response Elements Of The C-Fos Promoter And Involvement Of Intermediate Transcription Factor(S) In The Induction Of Sertoli Cell Differentiation (Transferrin Promoter Activation) By The Testicular Paracrine Factor Pmods*, Patricia D. Whaley, Jaideep Chaudhary, Andrea S. Cupp, Michael K. Skinner

Department of Animal Science: Faculty Publications

A mesenchymal-epithelial cell interaction exists in the testis between the Sertoli cells that form the seminiferous tubule and the mesenchymal-derived peritubular myoid cells that surround the tubule. Analysis of the mesenchymal-epithelial interactions between these cells revealed the local production of a mesenchymal factor, PModS. PModS modulates the differentiated functions of Sertoli cells in uitro, including stimulation of the iron-binding protein transferrin (Tf). Previous results have indicated that PModS-induced Tf gene expression involves the activation of immediate early genes. One of the immediate early genes was identified as c-fos. The importance of c-fos was demonstrated in the current study when a …

The Challenge And Opportunity Of Recovering Wolf Populations, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The gray wolf once inhabited a wide variety of habitats throughout most of the northern hemisphere north of 20°N latitude. Because the animal preyed on livestock and competed with humans for wild prey, it was extirpated from much of its range outside of wilderness areas. Environmental awareness in the late 1960s brought for the wolf legal protection, increased research, and favorable media coverage. The species has increased in both Europe and North America, is beginning to reoccupy semiwilderness and agricultural land, and is causing increased damage to livestock. Because of the wolfs high reproductive rate and long dispersal tendencies, the …

Three New Eimerians In Capybara (Hydrochaeris Hydrochaeris) Populations From Eastern Bolivia And Southern Venezuela, M. C. Casas, Donald W. Duszynski, L. M. Zalles

Harold W. Manter Laboratory of Parasitology: Faculty Publications

From June to August 1993, fecal samples were collected from the intestinal tract of 13 juvenile, 4 pre-adult, and 25 adult capybaras (Hydrochaeris hydrochaeris L.) from 10 localities in eastern Bolivia; additionally, 19 fresh fecal samples were collected in 1994 from capybara herds at 2 localities in south central Venezuela. Oocysts of 3 eimerians were recovered from the capybara populations in both countries and, after study, are described here as new species. Sporulated oocysts of Eimeria trinidadensis n. sp. are subspheroidal, 20.9 x 18.1 (18-23 x 16.5-21) μm with sporocysts ovoidal, 9.8 x 6.1 (8-12 x 5-8) μm. Micropyle …

Phylogenetic Relationships Of The Genera Of The Pronocephalidae Looss, 1902 (Digenea: Paramphistomiformes), Gerardo Pérez Ponce De León, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Quantitative phylogenetic analysis of 20 nominal genera of the Pronocephalidae based on 47 morphological transformation series produced 6 equally parsimonious trees, each with a consistency index of 77.8%. All trees agree that Adenogaster is the sister group to the rest of the pronocephalids, and a new subfamily is proposed for it. The Pronocephalinae comprises Pronocephalus, Ruicephalus, Neopronocephalus, Macravestibulum, Choanophorus, Cetiosaccus, and Metacetabulum. The Charaxicephalinae comprises Charaxicephalus, Desmogonius, Diaschistorchis, Pleurogonius, Iguanacola, Renigonius, Parapleurogonius, Himasomum, Pyelosomum, Cricocephalus, Barisomum, and Pseudobarisomum.

Evolutionary Origin Of Plasmodium And Other Apicomplexa Based On Rrna Genes, Ananias A. Escalante, Francisco J. Ayala

Harold W. Manter Laboratory of Parasitology: Library Materials

We have explored the evolutionary history of the Apicomplexa and two related protistan phyla, Dinozoa and Ciliophora, by comparing the nucleotide sequences of small subunit ribosomal RNA genes. We conclude that the Plasmodium lineage, to which the malarial parasites belong, diverged from other apicomplexan lineages (piroplasmids and coccidians) several hundred million years ago, perhaps even before the Cambrian. The Plasmodium radiation, which gave rise to several species parasitic to humans, occurred 129 million years ago; Plasmodium parasitism of humans has independently arisen several times. The origin of apicomplexans (Plasmodium), dinoflagellates, and ciliates may be >1 billion years old, …

Energy And Angular Distributions Of Electrons From Ion Impact On Atomic And Molecular Hydrogen. I. 20- 114-Kev H+ + H2, M. W. Gealy, G. W. Kerby, Iii, Y.-Y. Hsu, M. Eugene Rudd

M. Eugene Rudd Publications

Apparatus and procedures are described for the measurement of absolute cross sections, differential in ejected electron energy and angle, for ionization of atomic and molecular hydrogen by ion impact. A hemispherical electrostatic energy analyzer, rotatable from 15° to 165° with respect to the direction of the incident ion beam, was used to measure energy spectra of secondary electrons from 1.5 to 300 eV. Cross sections at ten angles (nine at some energies) and five incident-ion energies from 20 to 114 keV for H⁺ +H₂ collisions are given. The doubly differential cross sections were integrated over angle and electron …

Requirements For Publication In Insecta Mundi

Insecta Mundi

The quarterly journal, Insecta Mundi, is among the very few journals that have no page charges. However, since the Center for Systematic Entomology is entirely financed through dues, subscriptions, and cash donations, we have certain requirements for publication in the journal. (See also information on front inside cover of the journal.)

North American Members Of The Hydrellia Crassipes Species Group (Diptera: Ephydridae), D. L. Deonier

Insecta Mundi

The known members of the Hydrellia crassipes species group in North America are described or redescribed, including H. crassipes Cresson, H. procteri Cresson, H. saltator Deonier, H. amplecta n.sp., H. bryani n.sp., H. ocalae n.sp., and H. tibiospica n.sp. Adults of these species exhibit the following synapomorphies: dilated male metafemur and expanded (and flange din some) male metatibia and striate (fibrillate) distiphallus. Only a single species (H. tibiospica n.sp.) was reared from its host-plant species, Juncus debilis Gray, but there are associated habitat data to indicate that the entire species group may have sedges andrushes as host plants.

Bibliography On Hydrellia Griseola Fallen (Diptera: Ephydridae) And Review Of Its Biology And Pest Status, Louis S. Hesler

Insecta Mundi

A bibliography is presented on Hydrellia griseola (FallBn), a cosmopolitan species of shore fly that is an agricultural pest throughout much of its range. The literature review includes 195 references and spans 180 years: from 1813, when H. griseola was first described (as Notophila griseola), to 1993. My review updates and extends by 110 years a previous review of this species. The host plant associations, bionomics, distribution, pest status, and control of this species are reviewed. The known host plants of larval H.griseola are listed. My survey of the literature supports the hypothesis that H. griseola is increasing its …

Book Review: Bugs In The System By: May R. Berenbaum, Pierre Jolivet

Insecta Mundi

In one of her latest papers in the American Entomologist, in 1995, Prof. Berenbaum mentions how young people (and entomologists alike) are martyrizing insects and arachnids, by pulling their wings or their legs, burning them with magnifying glasses, without mentioning the lepidopterists who transfix the thorax of the female butterflies to induce them to lay eggs. Such behavior was once one of the acts of the emperor Nero when he was a child. His tutor, the philosopher Seneca, when he saw him pulling the wings off a fly, predicted that he would be very cruel. It was said t h …
