Histopathologic Alterations Associated With Syphacia Sp. (Nematode) In The Intestine Of Nesokia Indica, Nasira Khatoon, Fatima Mujib Bilqees, Dure Shahwar Jaffery, A. G. Rizwana

Turkish Journal of Zoology

The present work was undertaken to study the histopathological changes in the intestine of male rat Nesokia indica. Histopathological sections of infected intestine were prepared by fixing small pieces of intestine in buffer formalin for 24 h. The fixed material was washed with 70% alcohol and dehydrated and cleared for paraffin block making by the usual procedure. Sections of 5 to 7 µ thickness were used for the present study. E & H stained serial sections were mounted permanently in DPX. Sections were examined in detail and photomicrographs of selected sections were taken by Nikon (Optiphot-2) photomicroscope using Fuji colour …

Seasonal Larval And Adult Population Dynamics And Breeding Habitat Diversity Of Culex Theileri Theobald, 1903 (Diptera: Culicidae) In The Gölbaşı District, Ankara, Turkey, Fati̇h Mehmet Şi̇mşek

Turkish Journal of Zoology

In this research, which was carried out between August 1995 and July 1997 in an area that embraces Lakes Mogan and Eymir, Imrahor Valley and the Gölbaşı district of Ankara province, the seasonal larval and adult population dynamics, breeding habitat diversity and hibernation type of Culex theileri were studied and it was determined that 7 different habitat categories, such as marshes, lake shores, creek sides, pastures and animal footprints, can be breeding habitats for Cx. theileri and that it can be associated with 7 different mosquito species in these habitats. It was also established that larval and adult populations have …

Another Sandhill Crane Breeding Record In The Eastern Rainwater Basin, Joel G. Jorgensen

Nebraska Bird Review

Jorgensen (2002) recently summarized breeding-season occurrences of the Sandhill Crane (Grus canadensis) in the Eastern Rainwater Basin (eRWB). Summering birds were first detected in 1992 (The Nebraska Bird Review 60: 145). Breeding first occurred in 1994 with four additional nesting or breeding records in subsequent years. The most recent breeding records were in 1999 when breeding activity was detected at both Kissinger Basin Wildlife Management Area (WMA) (Hoffman 1999) and Harvard Waterfowl Production Area (WPA) (Silcock and Jorgensen 1999), both in Clay County. Since late 1999 the eRWB has experienced persistent drought. This has affected wetland conditions …

Breeding Black-Necked Stilts At Funk Waterfowl Production Area, Jeff Drahota

Nebraska Bird Review

On 21 July 2003, I was mapping wetland vegetation on Funk Waterfowl Production Area (WPA), Phelps County, when I encountered two adult Black-necked Stilts and two young on the Teal Unit, NE 1/4 of Section 16, T-6-N, R-17-W. I was using an airboat to map pockets of open water throughout the WPA. When I launched the airboat on the Teal Unit, I immediately noticed an adult Black-necked Stilt flying above the small pool. While driving the perimeter of this pool, I noticed two adult Black-necked Stilts continually flying over a small point of cattails surrounded by shallow water. As I …

Halsey Fall Field Days, Alice Kenitz

Nebraska Bird Review

Forty-one NOU members and friends gathered at the 4-H Camp at Halsey in the Nebraska National Forest on September 26–28, 2003, for the annual Fall Field Days. Fall colors were beautiful and the weather was generally good except for a brisk wind on Friday and Saturday. The ongoing drought was evident in the low level of lakes and ponds, with some of the smaller bodies of water being completely dry.

Fall Field Report, August-November 2003, W. Ross Silcock

Nebraska Bird Review

New in this Seasonal Report, direct from the American Ornithologists' Union (along with Wilson's Snipe, Rock Pigeon, etc.), is the modified checklist order, featuring geese, swans, and ducks at the beginning, followed by gallinaceous birds, then resuming the familiar order with loons.

Perhaps the most important use for these reports, in addition to their incorporation into the Southern Great Plains Region summary in North American Birds, is the noting of significant avian events in Nebraska. Some are of obvious importance, but the meaning of others is obscure, perhaps only to be revealed as subsequent reports show a trend, or …

Left-Sided Directional Bias Of Cloacal Contacts During House Sparrow Copulations, Karen B. Nyland, Michael P. Lombardo, Patrick A. Thorpe

Peer Reviewed Publications

Most female birds have only a left ovary and associated oviduct. The entry to the oviduct is on the left side of the urodeum of the cloaca. This arrangement may favor males that mount females from the left during copulation if it results in sperm being placed closer to the opening of the oviduct. Therefore, we predicted a left-sided directional bias of cloacal contacts during House Sparrow (Passer domesticus) copulations. Cloacal contacts from the left outnumbered those from the right 74 to 25 (3:1) during 25 bouts of copulation at 11 House Sparrow nests. While this pattern suggests …

Breeding Distribution And Habitat Use Of Audubon's Oriole In The Lower Rio Grande Valley Of Texas, Steven Gerald Monk

Theses and Dissertations - UTB/UTPA

Audubon's Oriole ( Icterus graduacauda ) was known historically throughout the Lower Rio Grande Valley (LRGV) of Texas, but its breeding range has now declined to mainly riparian habitat in Starr County. Habitat loss, degradation, and fragmentation, and brood parasitism by Bronzed Cowbirds ( Molothrus aeneus ) are likely causes of this decline. Habitat patches where Audubon's Orioles were present were larger, with a larger vertical range of canopy, greater vegetation volume, greater richness of bird and woody plant species, less local deforestation, and less local habitat fragmentation than where Audubon's Orioles were absent. Bronzed Cowbirds showed no numeric correlation …

The Role Of Facial Pits In The Thermoregulatory Behavior Of Pitvipers (Viperidae: Crotalinae) Behavioral, Ecological And Phylogenetic Perspectives, Aaron R. Krochmal

All-Inclusive List of Electronic Theses and Dissertations

Pitvipers (Viperidae: Crotalinae) possess unique sensory organs, the facial pits, capable of sensing subtle fluctuations in thermal radiation. Prey acquisition has long been regarded as the sole function of the facial pits. However, the ability to sense thermal radiation could also direct thermoregulatory behavior by remotely sensing nearby surface temperatures. Using a series ofbehavioral arenas of varying spatial complexity and ecological relevance, I surveyed the ability of western diamondback rattlesnakes (Crotalus atrox) to direct successful thermoregulatory movements with either functional or disabled facial pits. I found that western diamondback rattlesnakes could base thermoregulatory decisions on thermal radiation cues when their …

Summer Field Report, June-July 2003, W. Ross Silcock

Nebraska Bird Review

To begin on a sad note, I want to mention the passing of Roger Sharpe, senior author with Joel Jorgensen and me of Birds of Nebraska. Roger was great to work with, enthusiastic, and, of course, extremely knowledgeable in many areas. Joel and I both learned a lot from Roger, in different ways, not just ornithologically. We miss Roger.

This summer was, of course, hot and waterless. Any spot with water was a hotspot. Lake McConaughy, even more than usual, was worth a look, as were Sandhills ponds that generally fared well waterwise. Joel Jorgensen kept us posted on …

Geographic Variation In The Morphology Of Crotalus Horridus (Serpentes: Viperidae), John Robert Allsteadt

Biological Sciences Theses & Dissertations

The Timber Rattlesnake (Crotalus horridus) occurs in discontinuous populations throughout the eastern and central United States. The species exhibits high levels of polymorphism in morphological traits, especially in coloration and pattern. Previous studies recognized either distinct northern and southern subspecies or three regional morphs (northern, southern, and western), but conflicting data sets and limited geographic sampling of previous studies have left the relationships among those regional variants unclear. In this study, univariate and multivariate statistics, together with a geographic information system, were used to analyze geographic variation in 36 morphological characters recorded from 2,420 specimens of C. horridus …

Mechanical Properties Of The Integument Of The Common Gartersnake, Thamnophis Sirtalis (Serpentes: Colubridae), Gabriel Rivera

Biological Sciences Theses & Dissertations

The evolution of the ophidian feeding mechanism has involved substantial morphological restructuring associated with the ability to ingest relatively large prey. Previous studies examining the morphological consequences of macrophagy have concentrated on modifications of the skull and cephalic musculature. Although it is evident that macrophagy requires highly compliant skin, the mechanical properties of the ophidian integument have received limited attention, particularly in the context of feeding. I examined mechanical properties of skin along the body axis in male Thamnophis sirtalis (Colubridae). From each of 11 specimens, I examined nine circumferential strips of skin, each spanning 10 ventral scales, spaced at …

West Indian Mammals From The Albert Schwartz Collection: Biological And Historical Information, Robert M. Timm, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In the period 1954-1976, Albert Schwartz and several students working with him made extensive collections of mammals (ca. 2,000 specimens), reptiles and amphibians, birds, and butterflies in the West Indies. Schwartz's private collection of mammals from the West Indies is among the most comprehensive and important mammal collections from the region, yet much of it has never been reported in the scientific literature. Schwartz's original intent was to fully document all of the terrestrial mammals of the West Indies. In 1989, Schwartz transferred his mammal collection of some 6,500 specimens to the University of Kansas, and included in that collection …

Spring Field Report, March-May 2003, W. Ross Silcock

Nebraska Bird Review

This spring was characterized by a lack of significant ornithological events, although readers will find tidbits of interest under the following species: Greater White-fronted Goose, Mandarin Duck (believe it or not), Common Merganser, Peregrine Falcon, Buff-breasted Sandpiper, Great Horned Owl, and Blue-winged Warbler. A significant concentration of warblers and flycatchers was detected at Walnut Grove Park in Omaha in late May; check the species accounts for details. The restoration of prairie grasslands at Boyer Chute NWR seems to be paying off; Henslow's Sparrows were found there this spring for the first time. There were several new high counts, with perhaps …

Comparative Genome Organization Of Human, Murine, And Feline Mhc Class Ii Region, Naoya Yuhki, Thomas W. Beck, Robert M. Stephens, Yoko Nishigaki, Kymberly Newmann, Stephen J. O'Brien

Biology Faculty Articles

To study comparative molecular dynamics in the genesis of the major histocompatibility complex (MHC), we determined a complete nucleotide sequence spanning 758,291 bp of the domestic cat (Felis catus) extended and classical class II region. The feline class II MHC includes 44 genes (31 predicted to be expressed) which display DNA sequence homology and ordered gene synteny with human HLA and mouse H2, in extended class II and centromere proximal regions (DM to DO) of the classical class II region. However, remarkable genomic alterations including gene gain and loss plus size differentials of 250 kb are …

Thermoregulation In Swimming Mallard Ducklings (Anas Platyrhynchos), Aaron James Lynott

All-Inclusive List of Electronic Theses and Dissertations

Temperature regulation in birds has been studied for several decades. However, most studies have been limited to the thermal effects of air. This is surprising considering the abundance of waterfowl and the significant amount of time that many birds spend immersed in water. While we do know that water has a thermal conductivity that is 23 times that of air, the effect of water temperature on temperature regulation remains unknown. Though the thermal effect of water seemingly has a strong influence on the thermoregulation of birds, neonatal aquatic birds seem particularly susceptible. Many aquatic neonates, such as mallard ducklings, enter …

Movement Patterns In The Big Brown Bat (Eptesicus Fuscus), W. Adam Phelps

All-Inclusive List of Electronic Theses and Dissertations

Temperate insectivorous bats have historically used such structures as hollow trees, slabs of loose bark, foliage, and caves as roosts. With the advent of modern man in North America, human-built structures have become available to bats. Eptesicus fuscus is one of only two species of bats in the eastern United States that regularly utilize human structures as roosts, and the only one that regularly hibernates there. Individual ~- fuscus utilizing the attic of a church on the campus of St. Mary-of-the-Woods College (SMWC) were implanted with passive integrated transponder (PIT) tags. The electronic tag reader was placed near the only …
