Distribution Of The Porcupine, Erethizon Dorsatum, In Mexico, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The first Recent record of the porcupine, Erethizon dorsatum, from Mexico comprised fragmentary remains associated with human occupancy from a cave east of Cuatro Cienegas, Coahuila (Gilmore, 1947: 158-159). Later, Benson (1953 : 511-512) reported two specimens from western Sonora from < the lower flood plain of the Rio Sonora, close to the Gulf of California >> (one from 6 miles N Puerto Kino and the other from Rancho Santa Ana, about 45 miles W Hermosillo), and Dickerman (1962: 108) recorded the species from Hda. Las Margaritas in northern Coahuila. No additional reports of Recent porcupines from Mexico have come to our attention, and four specimens of Erethizon dorsatum couesi Mearns, 1897, in the Museum …

Notes On Bats From The Mexican State Of Zacatecas, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Much of the Mexican state of Zacatecas lies in the area ascribed to the Mexican Plateau. Along the western border and in the southwest, however, the state encompasses a portion of the Sierra Madre Occidental, and perhaps more importantly, from a zoogeographic view, the Rio Juchipila, a major tributary of the Rio Grande de Santiago, drains the southern "panhandle." The valley of the Juchipila supports tropical vegetation as perhaps do the valleys of several other smaller tributaries of the Rio Grande that barely reach the southern part of the state. The setting of southern Zacatecas suggests, therefore, considerable faunal diversity.

Bird Hybrids In The Kettle Moraine, Millicent S. Ficken

Field Station Bulletins

Since hybridization in birds is so rare in nature, it is unusual to have the opportunity to study what happens when two species interbreed. Blue-winged Warblers (Vermivora pinus) and Golden-winged Warblers (V. chrysoptera) produce hybrids wherever they occur together. Furthermore, such hybrids are fertile and there is pairing between these hybrids and both parental species. When we learned that both species breed in the northern Kettle Moraine State Forest, we decided to see what sorts of interactions between the two species were occurring there. Our objective initially was to determine if pairing was random between the species, e.g. were Blue-wings …

In Quest Of The Elusive Ovenbird, Charles M. Weise

Field Station Bulletins

The Ovenbird was selected for intensive study at the UWM Field Station for a variety of reasons. First, it is closely adapted in all respects-morphological, physiological, behavioral- to the upland forest environment, reaching maximum numbers in climax forests, such as the maple-beech forest which is under special investigation at the station. Second, because of its song it can be accurately censused and annual variations in numbers can be detected. Third, unlike most of the hard-wood forest birds, which spend most of their time in the tree canopy, the Ovenbird both nests and feeds on the ground, thus making it more …

Ticks Of The National Reactor Testing Station, Dorald M. Allred

Brigham Young University Science Bulletin, Biological Series

During the period from June, 1966, to September, 1967, 27 amphibians of two species, 446 reptiles of eight species, 561 birds of 81 species, and 4050 mammals of 26 species were examined for ectoparasites at the National Reactor Testing Station in southern Idaho. Of seven species of ticks collected, the predominant one was Ixodes kingi, found on mammals of 12 species. Next in abundance was Dermacentor andersoni found on birds of three species and mammals of 16 species. Haemaphysalis leporispalustris was taken from birds of 10 species and six spvecies of mammals. Four other species of Ixodes were taken from …

Osteology And Myology Of Phrynosoma P. Platyrhinos Girard And Phrynosoma D. Hernandesi Girard, Richard L. Jenkins, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

This study confirms the work of Etheridge (1964) in suggesting the peculiarity of the genus Phrynosoma within the family Iguanidae. The anterior osteology and myology of Phrynosoma platyrhinos platyrhinos Girard and Phrynosoma douglassi hernandesi Girard indicate Phrynosoma to be highly specialized and to differ significantlv from the Iguanid structure as portrayed by Oelrich (1956), Robison and Tanner (1962), and Avery and Tanner (1964). They also differ because of: ( 1 ) absence of lacrimal and postfrontal bones; (2) occurrence of occipital (also mandibular and temporal) spines; (3) posterodorsal shift of the skull elements; (4) divided nature of the M. sternohyoideus, …

Comparisons Of Phytoseiid Predator Populations In Sprayed And Unsprayed Apple Orchards In Cache Valley, Utah, Yeboa A. Dodoo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparative study of phytoseiid populations was made of two well-cultivated and regularly sprayed apple orchards with two unsprayed orchards in Cache Valley, northern Utah.

Two phytoseiid species, Typhlodromus mcgregori Chant and T. occidentalis Nesbitt were observed on the apple leaves, under the bark, and occasionally in the litter and soil. Amblyseius cucumeris (Oudemans) occurred in the soil and litter and occasionally under bark. T. mcgregori was dominant in the unsprayed orchards, and T. occidentalis in the sprayed.

Of the phytophagous mites, which served as food for the phytoseiids, the two-spotted mite, Tetranychus urticae Koch was dominant. Other phytophagous mites …

A Description Of The Planarian Phagocata Crenophila, New Species, From Utah, Jerry H. Carpenter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A new species of planaria in the genus Phagocata was found in several springs and spring-fed streams in Logan Canyon, Cache County, Utah. This species was named Phagocata crenophila because it greatly prefers to live in springs and it seems to be adapted behaviorally to this type of habitat. Serial sections and whole mounts were made by standard methods in order to study the anatomical features which are necessary for identification of planarians. The distinguishing features of this species are the following: testes ventral and extending from near the brain to near the posterior end, ejaculatory duct opening ventrally from …

Winter Bird Studies At The Uwm Field Station, Charles M. Weise

Field Station Bulletins

The winter trapping program was begun in the winter of 1965-66 and was expanded and conducted more systematically in 1966-67 and 1967-68. The primary objective has been to determine accurately the daily and seasonal changes in body weight and depot fat in the Chickadee and Junco. Secondarily, we (my students and I) have been interested in the winter population densities of these birds, their organization into social groups and flocks, their movements and range of activity in the local area.

A Census Of A Breeding Bird Population In A Virgin Spruce-Fir Forest On Mt. Guyot, Great Smoky Mountains National Park, Frederick Joseph Alsop

Masters Theses

Purpose of the study: The purpose of this study was to determine as accurately as possible the density of the bird populations in a virgin spruce-fir forest before changes in the forest resulting from aphid damage occurred. Accounts of the kinds of birds to be found in the spruce-fir biome are numerous. Some taken in the Southern Appalachians date almost one hundred years ago (Brewster, 1886). These reports give excellent records of the numbers of species to be found, but none give the numbers of individuals of each species, the density, to be expected for a given unit of measure …

Schistosome Dermatitis At Basswood Lake, Minnesota, James A. Zischke, Deloris Palmquist Zischke

Journal of the Minnesota Academy of Science

During the summer of 1965 cases of schistosome dermatitis were reported at the Associated Colleges of the Midwest Wilderness Field, Station on Basswood Lake, Minnesota. Collection and isolation of gastropods from the lake revealed an extremely high incidence of Trichobilharzia ocellata infections in Lymnaea stagnalis. A flock of semi-domestic mallard ducks first introduced al the lake in 1963 are believed to be the principal definitive hosts contributing to the epidemiology of the parasite in the area.

Radio-Tracking The Movements Of A Young Male Raccoon, Frank J. Turkowski, L. David Mech

Journal of the Minnesota Academy of Science

Movements of o young male raccoon (Procyon lotor) were studied for four months in 1965 through the use of an automatic radio-tracking system. Data for 135 days were collected, and 2,065 locations were recorded. The study animal usually rested throughout the day at different sites. Nightly activity usually began within an hour before or after sunset and ceased within an hour before or after sunrise; the mean duration of the active period was 9 hours and 5 minutes (S.E. = 19 minutes). Nightly movements varied both in extent and areas visited. The raccoon visited a certain cornfield on 87 per …

A Bull Snake Encounter With Young Ground Squirrels, Orrin J. Rongstad

Journal of the Minnesota Academy of Science

Apparent results of on encounter of a bull snake, Pituophis catenifer, with a litter of three thirteen-lined ground squirrels, Citellus tridecemlineatus, suggests that bull snakes may have eliminated young ground squirrels from a 3-acre lawn of the Cedar Creek Natural History Area at Bethel, Minn., during the summer of 1967.

Natural Selection In A Leopard Frog Population, David J. Merrell

Journal of the Minnesota Academy of Science

In a population of immature leopard frogs (Rana pipiens) at Mud Lake, Washington County, Minnesota, a high frequency of unilateral deformity of the hind legs was observed in 1965. Metamorphosis from tadpole to frog took place during July, and samples in late July averaged 14.8% deformed frogs. By late September, the frequency of deformed frogs had decreased to 3.6%, presumably as the result of natural selection.

Lead Shot In Some Spring Migrant Ducks, Robert L. Jessen, Dwain W. Warner, Francis A. Spurrell, John P. Lindmeier, Bertin W. Anderson

Journal of the Minnesota Academy of Science

The incidence of lead shot in l ,687 lesser scaup (Athya affinis) and 416 ring-necked ducks (Athya collaris) in spring migration in Minnesota and the implications as related to the bird population and hunting harvest the preceding fall are considered in this study. The ducks, which were examined for shot by photofluorographic radiography had died as a result of oil pollution on the Mississippi River in the vicinity of Red Wing in the spring of 1963. The birds were separated into two age groups and by sex. Yearling lesser scaup had a body shat incidence (proportion of birds containing shot) …

A 'New' Hybrid Minnow, Gary L. Phillips, David A. Etnier

Journal of the Minnesota Academy of Science

The specimen of a hybrid between the minnows Chrosomus erythrogaster and Dionda nubila is described. Taken in southeastern Minnesota near the known northernmost distributional limits of both parent species, this hybrid is between the parental extremes in most of the anatomical features examined.

Taxonomic Review : Miridae Of The Nevada Test Site And The Western United States, Harry H. Knight

Brigham Young University Science Bulletin, Biological Series

Approximately 5,000 specimens of plant bugs were collected at the Nevada Test Site between 1959 and 1965. Greatest emphasis was given to collecting from June 10–24, 1965, when the desert areas at the test site were unusually profuse with blooming vegetation. A total of 160 species representing 50 genera was taken at the test site. Of these, 7 genera and 96 species are new to science.

Comparative data for these and additional species from other parts of western North America are also included. These represent an additional 449 species, of which 5 genera and 148 species are new to science. …
