Food Of The Red Drum, Sciaenops Ocellata, From Mississippi Sound, Robin M. Overstreet, Richard W. Heard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fishes followed by polychaetes occurred as the most important items (in 99, 43, and 15% of the drum with food, respectively). Blue crabs occurred in even more drum than the frequently encountered penaeid shrimps. Other commercial species …

Nitrogen Fixation (Acetylene Reduction) Associated With Roots Of Winter Wheat And Sorghum In Nebraska, Wayne L. Pedersen, K. Chakrabarty, R. V. Klucas, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

Root segments and root-soil cores (6.5-cm diameter) from fields and nurseries of winter wheat and sorghum were tested for N₂ fixation by using the acetylene reduction assay. Wheat samples (~1,200) from 109 sites generally had low or no activity (0 to 3.1 nmol of C₂H₄ produced per h per g [dry weight] of root segments), even after 24 h of incubation. However, a commercial field of Scout 66, located in western Nebraska, exhibited appreciable activity (290 nmol of C₂H₄ produced per h per g [dry weight] of root segments). Of 400 sorghum lines …

Suppressed Rejection Of Trichinella Spiralis In Immunized Rats Concurrently Infected With Eimeria Nieschulzi, Donald W. Duszynski, Deborah Russell, Shirley A. Roy, Gilbert A. Castro

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This study deals with the effect of Eimeria nieschulzi infection on the host immune response to Trichinella spiralis. Six male Sprague-Dawley rats were inoculated with 10⁴ and six with 10⁶; sporulated E. nieschulzi oocysts. On days 2, 8, and 16 post-inoculation (PI), two rats from each infected group, and their paired uninfected controls, were killed and mucosal scrapings from their small intestines were assayed for peroxidase activity. Peroxidase levels were higher than corresponding control values on days 2 and 16 PI and significantly lower than the controls on day 8 PI. These data led us to …

Review Of Helminths Of Fish-Eating Birds Of The Palaearctic Region. I. Nematoda, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The title is accurate but the subject is a little misleading. One would expect that the fish-eating birds will acquire nematodes from the fish they eat. On the contrary, with one exception, Eustrongylides tubifex, as far as is known none of these nematodes use fish as normal intermediate hosts. A few species use fish as paratenic hosts. The book consists of an Introduction (2 pages), General Account of Nematodes (4 pages), the Systematic Part (233 pages), List of Fish-Eating Birds and Their Nematodes (22 pages), References (29 pages) and Index (13 pages). There are keys to families, genera, and …

Climatic Change And The Extinction Of Large Mammals During The Quaternary, C. Bertrand Schultz, John M. Hillerud

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

There is an abundance of soils and paleosols as well as terraces and terrace fills and erosional forms of pediments to aid in working out a precise stratigraphic sequence for the Quaternary animals. The dating and correlation of Quaternary deposits are complex, and we must realize that there were numerous glacial advances and retreats. A continuing reexamination of the relationship of the mammalian faunas to the paleosols, terrace fills, volcanic ashes, and other geologic features must be done in order to provide a proper framework for the interpretation of the mammalian stratigraphic sequences.

The horses and camels, which had so …

The Classical European Glacial Stages: Correlation With Deep-Sea Sediments, George Kukla

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Four glacials and three interglacials, recognized by classical Alpine and North-European subdivisions of the Pleistocene, were correlated with continuous oxygen-isotope records from the oceans using loess sections and terraces as a link (Fig. 15). It was found that the Alpine "glacial" stages are represented by sediments formed during both glacial and interglacial climates, that the classical Alpine "interglacial" stages do not represent episodes of interglacial climate but probably intervals of accelerated crustal movements, and that the physical evidence on which the North-European classical subdivision is based is misinterpreted due to lengthy gaps in the record.

It is recommended to discontinue …

The Origins Of Spring Migratory Staging By Sandhill Cranes And White-Fronted Geese, Roger S. Sharpe

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A most unusual avian migratory event takes place each spring in the Platte River basin of Nebraska between 98 and 102 degrees longitude (Fig. 1). In suitable habitats throughout this area large concentrations of Sandhill Cranes, Grus canadensis, and White-fronted Geese, Anser albifrons, develop and achieve peak populations in mid to late March. This phenomenon is traditional to the migratory habits of specific populations and occurs during the spring movement from wintering grounds in Texas, New Mexico, and Mexico to breeding grounds far to the north in Canada and Alaska. In both species groups of individuals drift in …

Excavations At Natural Trap Cave, Larry D. Martin, B. Miles Gilbert

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Among the more important questions addressed by students of earth history are those that relate to climatic change. This is especially true of change that has taken place during the last two million years of the "Ice Age." It is not an accident that a great deal of effort has been directed towards the Late Pleistocene, and our knowledge of Late Pleistocene environmental parameters has increased markedly in the past few years. However, our knowledge of these changes is still incomplete, and we still have some uncertainty about the cause and nature of Late Pleistocene climatic change, its possible relationship …

Predation On Furbearers And Management Alternatives, Ronald D. Andrews

Great Plains Wildlife Damage Control Workshop Proceedings

Most of the presentations from other members of the panel have discussed direct predation of one animal upon another with evidence and data to support it. Their presentations indicate that in some instances, considerable data has been collected that substantiates the fact that predation has been and can be a limiting factor in sustaining certain local animal populations. Suggestions have also been made concerning management alternatives that might help to reduce this predatory impact when desirable. Predation on furbearers and its impact is considerably more ambiguous and abstract. Facts and data concerning significant predation on furbearers, except for mink on …

Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe

Great Plains Wildlife Damage Control Workshop Proceedings

Distribution of the bobcat includes the 48 contiguous United States and limited occupance of southern Canada and northern Mexico. There are 11 subspecies, the one in Wyoming being Lynx rufus pallescens. Bobcats inhabit an amazing variety of habitat types, from northern boreal forests, southern swamp, and cane regions to the below sea level desert of Death Valley, California. Throughout this vast area, they utilize a wide variety of prey species. One study in Wyoming revealed at least 18 different species in the stomachs of bobcats; the cottontail rabbit being predominant. A similar study in New England revealed 20 different …

Prairie Dog Management: Educational Assistance To Local Governmental Units, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

There is a long history of involvement between Kansas State University (formerly Kansas State Agricultural College) and township governmental units regarding control of prairie dogs. In 1901 and 1903, the Kansas legislature passed laws authorizing townships to conduct prairie dog control programs and providing funds for the College to conduct experiments on methods of controlling prairie dogs and gophers. The acts also directed the College to procure and furnish to the townships the proper prepared materials for prairie dog control. The Experiment Station began supplying strychnine baits in January of 1902 and continued this practice until 1970.

Predation On Big Game And Its Management, Samuel L. Beasom

Great Plains Wildlife Damage Control Workshop Proceedings

This paper summarizes information from the literature and personal observation to present an overview of the effects of predators on big game populations. Specifically it examines control of prey populations, culling of inferior prey, and stimulation of prey productivity. Food habit investigations were omitted because of the impossibility of evaluating the impact of predation by this approach because of a lack of population data.

Productivity, Mortality, And Population Trends Of Wolves In Northeastern Minnesota, L. David Mech

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

Population parameters, mortality causes, and mechanisms of a population decline were studied in wolves (Canis lupus lycaon) from 1968 to 1976 in the Superior National Forest. The main method was aerial radio-tracking of 129 wolves and their packmates. Due to a decline in white-tailed deer (Odocoileus virginianus), the wolf population decreased during most of the study. Average annual productivity varied from 1.5 to 3.3 pups per litter, and annual mortality rates from 7 to 65 percent. Malnutrition and intraspecific strife accounted equally for 58 percent of the mortality; human causes accounted for the remainder. As wolf …

Habitat Use By Native Gambel' S And Scaled Quail And Released Masked Bobwhite Quail In Southern Arizona, John G. Goodwin Jr., C. Roger Hungerford

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Populations of both Gambel's and scaled quail surveyed in southern Arizona declined by 60% from October 1975 to June 1976. Masked bobwhite population density increased during the study because of additional releases, but survival patterns are uncertain. Raptors were efficient quail predators.

Gambel's quail were associated with a dense overstory of mesquite, hackberry, wolfberry, and catclaw. Understory species varied in density and appeared less essential to good habitat. Scaled quail preferred open, grass-shrub habitat, with few of the plants over 6 feet tall. Masked bobwhite selected dense, grass-weed habitat, with pigweed a characteristic species.

Green vegetation and insects were seasonally …

Wolf-Pack Buffer Zones As Prey Reservoirs, L. David Mech

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

Abstract. In a declining herd, surviving deer inhabited overlapping edges of wolf- pack territories. There, wolves hunted little until desperate, in order to avoid fatal encounters with neighbors. Such encounters reduce wolf numbers and predation pressure and apparently allow surviving deer along territory edges to repopulate the area through dispersal of their prime, less vulnerable offspring into territory cores.

Poecilancistrium Caryophyllum And Other Trypanorhynch Cestode Plerocercoids From The Musculature Of Cynoscion Nebulosus And Other Sciaenid Fishes In The Gulf Of Mexico, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examination of over 3,000 fish, all sciaenids, has shown that plerocercoids of Poecilancistrium caryophyllum infect Cynoscion nebulosus, Bairdiella chrysura, Sciaenops ocellata, C. arenarius, Micropogonias undulatus, and Pogonias cromis in Mississippi Sound. In addition to P. caryophyllum, a pseudophyllidean-like trypanorhynch also infected C. nebulosus and M. undulatus. Pseudogrillotia pleistacantha selectively infected large P. cromis, Pterobothrium heteracanthum infected M. undulatus, and Pterobothrium lintoni infected Menticirrhus americanus. Prevalence and intensity of infections of P. caryophyllum in C. nebulosus from Mississippi, roughly 40% of the fish each possessing an average of about two worms, …

Herpetomonas Megaseliae And Crithidia Harmosa: Growth On Blood-Agar Plates, Amy Doran Kepel, John J. Janovy Jr.

John J. Janovy, Jr. Publications

A technique for culturing two species of trypanosomatid flagellates on blood-agar plates is described. Herpetomonas megaseliae and Crithidia harmosa were grown as discrete clone colonies on plates prepared in sterile petri dishes with a medium derived from that of Tobie et al. (1950, J. Parasitol. 36: 48-54). Plates were inoculated with 0.01 ml flagellate suspension and the inoculum was spread evenly over the surface of the agar with a sterile glass spreader. Plates were incubated in a high humidity chamber at 25 C and colonies of both species, easily visible to the unaided eye, appeared within 1 week. There was …

Myxosoma Funduli Kudo 1918 (Protozoa: Myxosporida) In Fundulus Kansae: Summer Epizootiology, Stephen A. Knight, John J. Janovy Jr., William L. Current

John J. Janovy, Jr. Publications

The occurrence and distribution of the myxosporidan Myxosoma funduli on the gills of the plains killifish (Fundulus kansae) were investigated; Fundulus kansae is reported as a new host. Host samples from various sites on the South Platte River, Nebraska, were collected during the summer months of 1975 and 1976. The protozoan parasite population was shown to be overdispersed within the host population, and this distribution was similar to that described by the negative binomial equation. Demographic characteristics of the infected fish subpopulation were virtually identical to those of the whole fish population. Infection intensity was independent of gill …

Two New Zoogonid Digenea From Deep Sea Fishes In The Gulf Of Panama, Robin M. Overstreet, Mary Lou Hanson Pritchard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Panopula cavernossa gen. et sp. n. from the intestine of the brotulid Enchelybrotula (?) paucidens,/i> differs from other members of the Steganodermatinae by having testes near the anterior of the acetabulum, a posttesticular ovary, and a postequatorial acetabulum. Two related species are transferred to the genus Brachyenteron as B. pycnorganum comb. n. and B. spinosum comb. n. Neosteganoderma gillissi sp. n. from the synaphobranchid eel Synaphobranchus bathybius differs from N. glandulosum and N. polymixiae, the most similar species, because conspicuous glandular cells envelop the esophagus and pharynx, others about the genital atrium occur in elongated sacs, epithelium is lacking …

Marine Aspidogastrids (Trematoda) From Fishes In The Northern Gulf Of Mexico, Sherman S. Hendrix, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Of the aspidogastrids Multicalyx cristata, Lobatostoma ringens, Cotylogaster basiri, and C. dinosoides sp. n., the last two had not been previously known from the Gulf of Mexico. The latter differs from other members of its genus by having relatively large equatorial marginal alveoli in comparison to those at the anterior and posterior ends of the holdfast. It also possesses extensive transverse musculature connecting opposed lateral alveoli. New host records are included for all four species, and we report preadults of what appear to be the first two species.

Monoecocestus Thomasi Sp. N. (Cestoda: Anoplocephalidae) From The Northern Flying Squirrel, Glaucomys Sabrinus (Shaw), In Oregon, Robert L. Rausch, C. Maser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Monoecocestus thomasi sp. n. (Cestoda: Anoplocephalidae), from the northern flying squirrel, Glaucomys sabrinus (Shaw), in Oregon, is described and distinguished from its congeners. Monoecocestus thomasi is the sixth species of Monoecocestus to be described from nearctic rodents, and the first from a member of the family Sciuridae. Our comparisons of taxonomic characters of the nominal species of Monoecocestus in North American rodents have shown that M. giganticus Buhler 1970 is a synonym of M. americanus (Stiles 1895), both from the porcupine, Erethizon dorsatum (Linnaeus). Insemination in Monoecocestus spp. is discussed, with the conclusion that it takes place only by way …
