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.

Application Of The Nutrient Loading Concept To Lake Powell, The Effects Of Nutrient Perturbations On Phytoplankton Productivity, And Levels Of Nitrogen And Phosphorus In The Reservoir, Steven Paul Gloss

Biology ETDs

Levels, sources, and biological influence of nitrogen and phosphorus in Lake Powell, Utah-Arizona were examined. The reservoir, one of the three largest in the United States, is a mainstream impoundment on the Colorado River and is classified as a warm monomictic with meromixis exhibited in deeper waters.

Nutrient concentrations in the reservoir were characteristic of a mesotrophic lake. Mean total phosphorus concentration was 17 mg m^-3 during the study, while total nitrogen averaged 531 mg m^-3. Nitrate was the dominant form of nitrogen. Distribution of both nutrients exhibited patterns previously described for lakes to some extent, but …

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 …

Description Of The Larval Development Of Squilla Empusa Say (Crustacea Stomatopoda) With Aspects Of Larval Ecology In Chesapeake Bay, Steven Gaines Morgan

OES Theses and Dissertations

Larvae of Sguilla empusa were collected from the plankton and were reared in the laboratory to describe the pelagic larval development and the postlarval stage. Nine pelagic stages are passed through before the postlarval stage is attained.

The larvae reared for descriptive purposes were subjected to sixteen combinations of temperature and salinity to determine their tolerance to the two parameters. Larvae survived longer and molted more frequently when reared at 25°/oo and 20°C or 25°C, which corresponds to the natural conditions of the Chesapeake Bay when the larvae were collected.

A three year planktonic survey conducted in the lower region …

Plant Distribution And Succession Within Interdunal Depressions On A Virginia Barrier Dune System, Robert Wayne Tyndall

Biological Sciences Theses & Dissertations

A unique series of interdunal depressions was recognized on the barrier dune system of southeastern Virginia. Plant distribution and succession, and environmental factors controlling them, were studied in the series. Plant community distribution appears to be predominantly controlled by soil moisture, interspecific competition, and feral hog disturbance. Both biotic and physiographic succession are apparent with Quercus virginiana probably climax for both. Salt spray and feral hog and migratory waterfowl activity are important controlling factors of plant succession. Results indicate that the zonal appearance of shrubs and trees on the Virginia and North Carolina coasts is due to the absence of …

A Flora Of The San Andres National Wildlife Refuge, Dona Ana County, New Mexico, James Duwayne Von Loh

Biology ETDs

The San Andres Mountains are a unique range. Their narrowness and relatively small mass create environmental conditions that allow elements of the Chihuahuan Desert flora, Upper Sonoran Desert flora, and representatives of the southern Rocky Mountain flora to intermingle, forming an extremely diverse, mosaic pattern of dispersal. San Andres National Wildlife Refuge was studied floristically during the 1975 growing season. It is represented by 923 known species of vascular plants from four distinct topographical areas that span a 4000 to 8200 foot elevational range. The study resulted in 1422 collections from the San Andres Mountains. Specimens from the Refuge area …

Bird Use Of Revetted Riverbanks In The Willamette Valley, Clifford Brian Perry

Dissertations and Theses

Over 115 miles of rock revetments that serve to protect river banks have been constructed in the Willamette Basin. In this study the spring and summer bird use of Willamette Basin revetments is examined. Revetments that had not been recently cleared of most woody vegetation and blackberries were found to have significantly greater total and breeding bird use than cleared revetments. Possible factors affecting bird use, such as vegetation on revetments and vegetation adjacent to revetments are examined using linear regression analysis. The results of this study are compared with results of previous work in riparian forests along the Columbia …

An Evaluation Of Narrow Hybrid Zones In Vertebrates, William S. Moore

Biological Sciences Faculty Research Publications

A review of the literature on vertebrate hybridization reveals the existence of a number of narrow hybrid zones. Three hypotheses have been suggested to explain the occurrence of these zones. The ephemeral-zone hypothesis states that hybridization will end either in speciation or fusion of the hybridizing taxa by means of introgression. The dynamic-equilibrium hypothesis allows the possibility that narrow hybrid zones might be stable: where hybrids are confined to a small area by steep selection gradients, "crystallization" of an antihybridization mechanism might be prevented by naive immigrants from the parental populations even though hybrids are selected against. The hybrid-superiority hypothesis …

Comparison Of Coyote And Coyote × Dog Hybrid Food Habits In Southeastern Nebraska, Brian R. Mahan

University of Nebraska State Museum: Mammalogy Papers

The recent taxonomic study by Mahan et al. (1978) documented the occurrence of coyote (Canis latrans) x dog (c. familiaris) hybrids in Nebraska. This study, and those by Freeman (1976) in Oklahoma and Gipson et al. (1974) in Arkansas show coyote x dog hybrids, though not abundant, to be numerous in some areas. The purpose of the present study was to compare the stomach contents of coyote x dog hybrids collected by Mahan et al. (1978) from southeastern Nebraska with those of contemporary coyotes.

Stomachs of 12 coyote x dog hybrids and 16 coyotes collected November 1975 …

Contractile Properties Of Rat Soleus Muscle: Effects Of Training And Fatigue, Robert H. Fitts, J. O. Holloszy

Biological Sciences Faculty Research and Publications

The effects of exercise training and fatigue on the contractile properties of rat soleus muscles have been investigated. Prolonged exercise, consisting of 2 h or daily treadmill running, induced small but significant decrease in contraction time, one-half relaxation time, and maximum tetanic tension (Po), and increase in the peak rate of tension development (dP/dt) during a twitch, and an increase in maximum shortening velocity (Vmax). The 20% increase in Vmax was proportional to the previously reported increase in actomyosin ATPase induced by 2 h of daily running. These results indicate that prolonged training can induce modifications of the neurally determined …

Modern Invertebrate Footprints Compared With Fossil Footprints From The Coconino Sandstone (Permian), Marilyn A. Emtage

Loma Linda University Electronic Theses, Dissertations & Projects

Laboratory studies of trackways of the crayfish, Cambarus clarkii were conducted, and the footprints compared with fossil invertebrate footprints (Paleohelcura sp.) of the Permian Coconino sandstone of Northern Arizona, and similar footprints of other sandstone. Fine grained sand (similar to that composing the Coconino sandstone) was placed in a plexiglass tank to form slopes of various angles. The crayfish walked up and down slopes of 10°± 3°, 20°± 2°, 25° and on level sand, and their trackways were photographed. Trackways were produced on wet sand and underwater sand, but the animals would not walk on dry sand. Clear individual impressions …

Megafossil Orientation Of Selected Silurian, Devonian, And Pleistocene Reefs Of North America, Lance T. Hodges

Loma Linda University Electronic Theses, Dissertations & Projects

The definition and identification of fossil reefs has been a continually vexing problem for paleoecologists. One approach to this problem is a study of fossil orientation in "reef" strata. Orientation of corals in exposures of reef limestones has been mentioned in the literature, but usually in a brief, non-quantitative way. Eight study sites were used to investigate the nature of structures described as reef-related. Two sites were selected from the Pleistocene Key Largo Limestone of Florida, probably a backreef facies. The Florida sites were used as fossil reef reference sites, because of their close relationship to modern Florida reefs. The …

Distribution And Behavior Study Of Diurnal Tree Squirrels In Portland, Oregon, With Emphasis On The Western Gray Squirrel (Sciurus Griseus Griseus Ord) And The Western Fox Squirrel (S. Niger Rufiventer E. Geoffroy St.-Hilaire), Ira Young Rice Iii

Dissertations and Theses

Populations of diurnal tree squirrels in the Portland area were located by mail surveys, personal interviews, and field inspections. Pine squirrels were found to reside in thickly wooded residential areas with dense understories and running water nearby. Western gray squirrels occupied habitats in relatively quiet residential neighborhoods, in areas well supplied with mast crops. Western fox squirrels were found to coexist with gray squirrels in their preferred habitat, and also to thrive in park settings with few mast trees and high activity and noise levels. In areas occupied by both fox and gray squirrels, dominant-subordinate relationships were noted. Each species …
