Seasonal Abundance And Habitat Distribution Of Birds In Northeastern Arkansas, Earl L. Hanebrink, Alan F. Posey

Journal of the Arkansas Academy of Science

Bird sighting records from 1964 through 1978 for 17 northeastern Arkansas counties were compiled according to the seasonal status, relative abundance and habitat distribution of each species. The five seasonal occurrence categories and their relative species composition were: transient visitant (46.6%), summer resident (20.3%), winter resident (14.8%), permanent resident (17.2%) and winter visitant (1.0%). The seven seasonal abundance categories and their relative species composition were: very rare (13.9%), rare 15.9%), uncommon (30.7%), fairly common (10.5%), common (25.6%), very common (1.7%) and abundant (1.7%). Eleven habitat categories were included: campestrian, abandoned fields, forest edge, lowland woods, upland woods, riparian woods, marshes, …

Effect Of Turf Fungicides On Earthworms, J. H. Roark, J. L. Dale

Journal of the Arkansas Academy of Science

Numerous turf fungicides were tested under various conditions for possible deleterious effects upon the earthworm Eisenla foetida. Earthworms treated by immersion for one minute in 0.1% solutions of 10 different fungicides died insignificant numbers after benomyl and thiophanate methyl treatments. After 1% fungicide treatments, there was significant mortality from benomyl, ethazole, Kromad, and thiophanate methyl fungicides. With 2% fungicide solutions, significant numbers died after benomyl, cadmium succinate, ethazole, thiophanate methyl, and thiram treatments. Earthworms fed bermudagrass clippings treated with 10 different fungicides showed a significant decrease in longevity from clippings treated with benomyl, dinocap, ethazole, and thiophanate methyl. Earthworms reared …

Flystrike In Sheep : Secondary And Tertiary Flies Striking Sheep In Western Australia, N Monzu

Journal of the Department of Agriculture, Western Australia, Series 4

Unlike primary species of blowflies, the secondary and tertiary species of flies cannot initiate a strike, but their activity in the presence of the primary blowflies becomes significant in the death of struck sheep. This is particularily so when the hairy maggot blowfly is involved. Future management of sheep flocks to minimise deaths may require recognition of these secondary and tirtiary flies.

This article presents some basic facts about these flies.

Rabbits (Genus Sylvilagus) Of Nicaragua, Terry L. Yates, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The rabbits (genus Sylvilagus) of Nicaragua are herein reviewed systematically. Geographic and nongeographic variation has been assessed based on examination of 124 museum specimens constituting 28 samples of Sylvilagus floridanus from Honduras, Nicaragua, and Costa Rica, and 15 samples of S. brasiliensis from Nicaragua and Costa Rica. Morphological features of the skin and skull were analyzed using various univariate and multivariate statistical techniques. Analysis of geographic variation in S. floridanus indicates that rabbits of this species in Nicaragua are referable to the subspecies S. f. costaricensis, rather than to S. f. hondurensis as previously believed. Based on our …

Differentiation Of Fourth And Early Fifth Stages Of Parascaris Equorum (Goeze, 1782) Nematoda: Ascaridoidea, P. A. Pilitt, J. R. Lichtenfels, P. A. Madden

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The morphology of Parascaris equorum of horses was studied; light and scanning electron microscopy were used. Late fourth-stage larvae have narrow, rectangular lips bearing few, large. triangular, irregularly spaced denticles and the lips are not markedly set off from the body. The cutick of the late fourth stage is completely transversely striated, with incomplete longitudinal ridges creating a brickwork pattern; longitudinal alae are present. Total body lengths of fourth-stage larvae range from 10 to 32 mm. A single molting fourth-stage male was found to be 33 mm long. Early fifthstage nematodes have wide, trilobate lips with a deep transverse groove …

The American Wood Quails Odontophorus, Paul A. Johnsgard

Paul Johnsgard Collection

It is ironic that the genus of New World quails that not only has the greatest collective geographic range (from central Mexico to northeastern Argentina) but also the largest number of species (12 or more, varying with the authority), is one of the least known groups of American gallinaceous birds. This is in large measure the result of the fact that all of the species are forest-adapted, and generally are associated with tropical to sub-tropical communities, where opportunities for easy observation are virtually absent.

Not only is this the largest genus of the subfamily Odontophorinae, but also the species tend …

Sperm Morphology, G. Lawrence Forman, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Bishop and Austin (1957) in their study of variation in mammalian spermatozoa suggested that the sperm of each mammalian species was probably unique. Although complete volumes have been written on the ultrastructure of spermatozoa (for example Baccetti, 1970), particularly of humans and domestic animals, there is still relatively little information available on the comparative gross morphology of spermatozoa. McFarlane (1963), Forman (1968), and Forman et at. (1968) made significant contributions to our understanding of the use of sperm morphology in establishing systematic and phylogenetic relationships of birds and mammals. However, there have been very few similar studies published to this …

Morphometrics [Of Phyllostomatid Bats], Pierre Swanepoel, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In this paper, we have attempted to cite all relevant literature in which mensural
data pertaining to phyllostomatid bats has appeared. We are not so naive as to
believe this goal was reached, but we do believe most pertinent publications
are listed, including all major works relating to each species. This information
serves as a summary of what currently is known concerning morphometrics of
phyllostomatids and hopefully provides a basis for future morphometric studies
of members of the family.

The Parasitic Coelenterate, Polypodium Hydriforme Ussov, From The Eggs Of The American Acipenseri From Polyodon Spathula, Glenn L. Hoffman, E. V. Raikova, V. Ch. Suppes

United States Fish and Wildlife Service: Publications

No significant differences in macro- and micromorphology were found between the parasitic stolon and free-living polyps of Polypodium sp. obtained from infected eggs of the North American acipenseriform fish Polyodon spathula and corresponding developmental stages of Polypodium hydriforme Ussov, parasitic in the Volga sterlet (Acipenser ruthenus). Therefore, both the American and the European forms of Polypodium belong to the species P. hydriforme Ussov

Histology Of Dichromatic And Seasonal Color Change Of The Cranial Region Of Callagur Borneoensis, Kevin William Matson

Masters Theses

Male Callagur borneoensis exihibit sexual dichromatism and seasonal coloration which is rare among turtles. In the breeding season male's heads are colored white with a scarlet stripe from the occiput to the tip of the snout. After the breeding season they change to drab charcoal-gray to black with a dull orange-yellow stripe. Females and juveniles are a drab brown throughout the year.

This study was performed to determine the mechanisms of this color change at the histological level. Histological preparation of the head revealed a significant increase in vascular tissue just below the epidermis of the stripe area with increased …

Coccidian Parasites Of Wild Turkeys, Meleagris Gallopavo Silvestris, In Illinois, D. Michael Watkins

Masters Theses

Fecal samples from 124 wild turkeys (Meleagris gallopavo silvestris), collected in three southern Illinois counties, were examined for coccidia. Three and two tenths percent (4) of the birds sampled were infected with Eimeria of apparently four different species. These species were tentatively designated as: E. meleagridis, E. adendeides, E. meleagrimitis and E. subrotunda.

The Ecology Of Invertebrate Drift And Feeding Chronology Of The Striped Shiner, Notropis Chrysocephalus (Rafinesque) In Polecat Creek, Illinois, Dennis L. Newman

Masters Theses

The downstream drift of macroinvertebrates and the daily feeding cycle of the striped shiner, Notropis chrysocephalus (Rafinesque), were studied during the spring and summer of 1978 in Polecat Creek, Illinois. The purpose of the study was to: investigate the drift phenomenon of an entire lotic community, determine the pattern of diel periodicity for several important benthic populations, make qualitative and quantitative assessments of the relation of drift to benthos, and examine drift in relation to the daily feeding ecology of a cyprinid carnivore.

Polecat Creek at the sampling site was a relatively fast-flowing third-order stream, with frequent riffles. Drift sampling …

Development Of Pelagic Larvae And Postlarva Of Squilla Empusa (Crustacea, Stomatopoda), With An Assessment Of Larval Characters Within The Squillidae, Steven G. Morgan, Anthony J. Provenzano Jr.

OES Faculty Publications

Larvae of the predatory crustacean Squilla empusa were collected from the plankton in Chesapeake Bay and reared in the laboratory to permit description of the pelagic stages before the postlarval stage.

Characters such as rostral length and spinulation, carapace spinulation, relative size of telson, overall body size, and appearance probably are of more value for specific than for generic identification. The presence or absence of teeth on the dactylus of the second maxilliped, the presence or absence of a spine on the basis of the second maxilliped, and the number of epipods may be useful characters in determining generic alliances …

Feeding Studies On Three Species Of Fish From Tomales Bay, California, John Brezina

University of the Pacific Theses and Dissertations

The study of fish diets or feeding behavior is an important aspect in ecology. Analysis of fish stomach contents often provides data for determining resource utilization, feeding strategies, and overlaps in food items among and between species. Studies of fish diets could also be used for testing ecological theory or provide management procedures for fisheries if methods could be developed for minimizing competitive food utilizations by other fish and enhancing growth of exloited fish populations (Obrebski and Sibert 1977). In order to understand more about ecological communities and competitive predatory relationships of fish, more data are required on their diets …

The Comparative Ecology Of Two Populations Of The Troglobitic Isopod Crustacean Lirceus Usdagalun (Asellidae), James Alexander Estes

Biological Sciences Theses & Dissertations

Aquatic communities of two caves in Lee Co., Virginia, were compared, and an examination was made of the life history phenomena of the troglobitic isopod Lirceus usdagalun. Measurements of physical and biological parameters were made in Thompson Cedar Cave and Gallohan Cave No. l. A contagious distribution was exhibited by populations of L. usdagalun in both caves and also by the population of another troglobitic isopod, Caecidotea recurvata, in Gallohan Cave No. 1. This distribution was attributed to aggregations of individuals which were considered to occur in areas of preference or optimal habitat patches. Lirceus usdagalun exhibited a …

Revision Of The Antillean Bats Of The Genus Brachyphylla (Mammalia: Phyllostomatidae), Pierre Swanepoel, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Nongeographic and geographic variation have been analyzed in the genus Brachyphylla. which belongs to the Antillean endemic subfamily Phyllonycterinae of the family Phylloslomatidae. Males were found to be generally larger than females: therefore, the sexes were analyzed separately for geographic variation. External measurements except length of forearm were found to displaya high degree of individual variation. They were not used in subsequent analyses. Of cranial measurements, greatest length of skull and condylobasal length showed the least individual variation, whereas palatal length, postorbital breadth (in samples from west of the Mona Passage only), and rostral width at canines showed relatively …

Evaluation Of Body Size Parameters In Elite Angus Cattle, Wilson Stone

Masters Theses & Specialist Projects

The cattle shown at the prestigious All-American Angus Futurity were studied in order to evaluate the relationship between various body measurements. The measurements taken included wither height, hip height, body length, fat thickness,and weight. Also, these measurements were analyzed in order to determine if Angus cattle had gained in genetic frame size. Data were collected for the 805 animals shown in the years 1974 through 1978.

The cattle were grouped into classes based upon sex and age prior to any statistical procedures being performed. Means of classes were used in order to evaluate sex differences and bulls were found to …

The Ornithogeography Of The Great Plains States, Paul A. Johnsgard

Paul Johnsgard Collection

It has long been recognized that the Great Plains represent a major transition zone in the distribution patterns of North American birds; field guides traditionally have treated the 100° W. longitude meridian as a convenient dividing line between eastern and western faunas. Furthermore, this line rather neatly bisects the political subdivisions of the Great Plains, namely the "plains states" extending from North Dakota southward through South Dakota, Nebraska, Oklahoma, and Texas. Of these, Texas is the least typical, its climate and fauna is strongly influenced by the Gulf Coast on the east and the Chihuahuan desert on the west. As …
