Macrobenthic Invertebrate Fauna Of Lake Eğrigöl (Gündoğmuş - Antalya), Seray Yildiz, Ayşe Taşdemi̇r, Murat Özbek, Süleyman Balik, M. Ruşen Ustaoğlu
Turkish Journal of Zoology
In order to determine the macrobenthic invertebrate fauna of Lake Eğrigöl, located at 2000 m in the central Taurus Mountains, 4 field studies were conducted between June and September, 2000, and June and September, 2001. The specimens were obtained by collection of mud samples using an Ekman-Birge grab and by sifting with a fine 500 µm sieve, and were preserved in 4% formaldehyde solution. Additional samplings were also performed from the shore with hand nets with a mesh size of 180 µm. On average, 1036 benthic invertebrate specimens were found per square meter in Lake Eğrigöl; 939 of these specimens …

The Histochemical And Ultrastructural Effects Of Cadmium On Mouse Edl Muscle, Fati̇me Geyi̇koğlu, Aysel Temelli̇, Özgen Vuraler, Hasan Türkez
Turkish Journal of Zoology
The histochemical and ultrastructural effects of cadmium (Cd) on the extensor digitorum longus (EDL) muscles of male mice were investigated. Two doses of Cd (0.1 and 1.0 x 10^{-4} M) were injected into the mice. The animals were killed at the end of 48 h and their EDL muscles excised. Three types of fibers (I, IIA and IIB) were described by the succinic dehydrogenase (SDH) method in the control groups. The mitochondrial and sarcotubular contents of the fibers were different. The histochemical and ultrastructural characteristics of the EDL muscles in mice given Cd did not differ from those of the …

The 2002 Nebraska Nest Report, Wayne Mollhoff
The 2002 Nebraska Nest Report, Wayne Mollhoff
Nebraska Bird Review
In contrast to last year, with "the winter that wouldn't end," this breeding season began with a "spring that wouldn't begin." The winter was mild and uneventful, but although the spring was neither cold nor stormy, the usual warm-up did not come, and when the weather finally warmed in May, it brought no moisture. The resulting drought was worst in the west and southwest, areas that had already been abnormally dry for several years. In mid-June in the southern Panhandle, many ranchers were still feeding hay to the cattle because the grass simply did not grow. The dry conditions surely …
Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton
Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton
Nebraska Bird Review
Since 1992 the Central Nebraska Public Power and Irrigation District (Central) has protected and monitored nesting Piping Plovers along the shore of Lake McConaughy (Keith County, Nebraska). Over those 13 seasons, Central monitored 849 Piping Plover nests and documented the successful fledging (successful fledging is defined as a chick at least 24 days old, or one observed flying) of 1,237 Piping Plover chicks (Table 1), making Lake McConaughy one of the most productive nesting areas for Piping Plovers in Nebraska. The following is a documentation of the contributions of Lake McConaughy to the recovery goals for Piping Plovers in Nebraska. …
Fall Field Report, August-November 2004, W. Ross Silcock
Fall Field Report, August-November 2004, W. Ross Silcock
Nebraska Bird Review
The fall season is a mix of summer, fall migration, and winter. Thus there are breeding records of interest, such as Mississippi Kites nesting at Red Cloud, only the 2nd known location in Nebraska, and only the 3rd documented breeding record for Northern Parula, despite its common summer residency. Fall migration generates early arrival dates, high counts, and late departure dates, the last seemingly more numerous as our average temperatures increase. Included in the late departure category were several late shorebirds, Great Egret and White-faced Ibis, and even the latest ever Black-throated Blue Warbler.
Counts of interest were 3000 Double-crested …
Does Birding Have A Future?, Rick Wright
Does Birding Have A Future?, Rick Wright
Nebraska Bird Review
Does birding have a future?
Now this might seem an odd question, even an absurd question, to pose to an audience like this, and the answer might seem obvious. How could birding not have a future when we, all of us, are birders who bird, and when survey after recent survey assures us that our numbers are growing, our diversity increasing, and our economic and ethical contributions to American society ever more conspicuous. Does birding have a future? The simple answer is yes.
That's the simple answer. The more interesting answer is yes-yes, but. Yes, birding has a future, but …

Eight traditional subspecies of tiger (Panthera tigris), of which three recently became extinct, are commonly recognized on the basis of geographic isolation and morphological characteristics. To investigate the species' evolutionary history and to establish objective methods for subspecies recognition, voucher specimens of blood, skin, hair, and/or skin biopsies from 134 tigers with verified geographic origins or heritage across the whole distribution range were examined for three molecular markers: (1) 4.0 kb of mitochondrial DNA (mtDNA) sequence; (2) allele variation in the nuclear major histocompatibility complex class II DRB gene; and (3) composite nuclear microsatellite genotypes based on 30 loci.

Use Of Cre Recombinase And Sb Transposase To Engineer Transgenic Zebrafish, Jie Dong
Use Of Cre Recombinase And Sb Transposase To Engineer Transgenic Zebrafish, Jie Dong
All-Inclusive List of Electronic Theses and Dissertations
Current transgenesis has become easier for certain species due to the recent development of exogenous non site-specific recombination systems such as Sleeping Beauty (SB) transposon, and site-specific recombination systems such as Cre-loxP. Such recombination systems overcame two major problems caused by conventional transgenesis, position effect and copy number effect. SB is a reconstructed fish transposon that has shown to efficiently insert transgenes into heterologous mammalian chromosomes. The Cre-loxP system is frequently used to delete a given sequence from the genome or to target the integration of foreign DNA. The use of both systems in combination, however, has not yet been …

The Ecology And Relationships Of Chiropteran Ectoparasitic Communities Of Indiana, Christopher Michael Ritzi
All-Inclusive List of Electronic Theses and Dissertations
The ectoparasites of bats are an important and largely unstudied area of mammalian ecology. The structure of ectoparasitic communities on bats, and their interactions with their hosts, may help in the understanding of roosting ecology, pa1iurition, and other aspects of host natural history. In this study, a vigorous survey of the ectoparasitic fauna of the bats ofindiana was undertaken, to determine if changes in species composition has occurred over the past 30 years. This survey resulted in the recovery of 51,980 parasites of 13 families from 2,816 host individuals of l O species, documenting 16 new host records and 14 …

The Florida Bonneted Bat, Eumops Floridanus (Chiroptera: Molossidae): Distribution, Morphometrics, Systematics, And Ecology, Robert M. Timm, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
A review and reappraisal of bats of the genus Eumops (Chiroptera: Molossidae) reveals that considerable geographic variation is present in the bonneted bat, E. glaucinus; it is a complex consisting of >1 species. Bonneted bats in Florida are significantly larger than those in all other populations, and have proportionally shorter and deeper basisphenoid pits, the glenoid fossa is broadly triangular with rounded apices, and bacular shape differs from that in other populations. Additionally, bonneted bats in Florida have a broader palate than bats from populations in South America. Given these differences, the correct name for both Pleistocene and Recent …

Long-time NOU member Clyde Johnson passed away on May 4, 2003. He is survived by his wife Emma, who now resides in Fredericksburg, Texas.
Clyde and Emma lived in Omaha, where Clyde was employed as an insurance agent. They made numerous birding trips to Central America, Europe and Asia. Few other details of his life are available, which is quite likely just the way Clyde wanted it. Although Clyde was quiet about his personal life, he was well known among NOU members for his contributions of time, enthusiasm and money to the organization.

The 2001 Nebraska Nesting Report, Wayne Mollhoff
The 2001 Nebraska Nesting Report, Wayne Mollhoff
Nebraska Bird Review
The spring of 2001 will likely be remembered as the winter that wouldn't end, especially in central and western Nebraska. The last remnants of roadside snowbanks remained in the east until 10 April, but the last blizzard closed down the Panhandle on 21-22 April, and the last appreciable snowfall there was on 19 May. None of these dates represent late records, but are remarkably later than average for the past 10-15 years, and seemed especially burdensome following the long cold winter and the remarkably early spring the previous year.
While I recognize the danger inherent in making generalizations when working …

Birds Of Spring Creek Prairie Audubon Center - 1999-2004, Kevin Poague
Nebraska Bird Review
In the summer of 1998, Audubon Nebraska, a state office of the National Audubon Society, purchased the 610-acre O'Brien Ranch located three miles south of Denton, Nebraska. The site, now called Spring Creek Prairie Audubon Center (SCPAC), will be devoted to prairie education and restoration. The Center's size expanded to 626 acres in 2000 when the Wachiska Audubon Society bought an adjacent 16-acre property on the northwest comer of the section.
Historically, most of the ranch was never farmed, probably because of its hills and the large number of glacial boulders present in the soil. It is one of the …

Summer Field Report, June-July 2004, W. Ross Silcock
Nebraska Bird Review
The coverage of the state by observers who report their sightings, mostly to the listserv NEBirds, is very good relative to their rather low number. Even so, there are parts of the state that are only recently revealing their secrets. Extensive work in the Panhandle in the late 1990s, including mist-netting by Steve Dinsmore, showed that several western species are regular migrants through that part of the state, and similar extensive coverage of waterbirds and shorebirds at Lake McConaughy yielded similar valuable information, following the pioneering efforts there by Dick Rosche. This report contains many references to another interesting area …

The Greater Snow Goose (Chen Caerulescens Atlanticus) In Nebraska, W. Ross Silcock
Nebraska Bird Review
Recently, Mr. William Lemburg of Cairo, Nebraska, in a letter to the Editor of the Nebraska Bird Review, noted the following: "I have a friend who does quite a bit of goose hunting. He remarked to me that during the spring snow goose season, he occasionally shoots an extra-large Snow. Thinking that maybe a few Greater Snows that winter along the Atlantic Coast may end up in the Central Flyway, I asked him to save the head of one if he bagged one the following season. This is about five years ago. The following season he did get one. …

Historical Biogeography Of The Woodchuck (Marmota Monax Bunkeri) In Nebraska And Northern Kansas, Zachary P. Roehrs, Hugh H. Genoways
Historical Biogeography Of The Woodchuck (Marmota Monax Bunkeri) In Nebraska And Northern Kansas, Zachary P. Roehrs, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Discusses the historical biogeography of the Woodchuck (Marmota monax bunkeri) in Nebraska and northern Kansas.
First paragraph:
Jones et al. described the western limit of Marmota monax in the United States as the eastern edge of the northern Great Plains in Oklahoma, Kansas, Nebraska, and the Dakotas. Mengel introduced the idea of the Great Plains grasslands as a barrier to contact between birds of eastern and western North American forests. In his studies of bird biogeography on the Platte River, Knopf reported that this barrier has eroded with development of riparian forests along river courses of the Great …
Thermal Adaptation Of Maternal And Embryonic Phenotypes In A Wide Spread Lizard (Sceloporus Undulatus), Christopher E. Oufiero
Thermal Adaptation Of Maternal And Embryonic Phenotypes In A Wide Spread Lizard (Sceloporus Undulatus), Christopher E. Oufiero
All-Inclusive List of Electronic Theses and Dissertations
Geographically widespread ectotherms encounter thermal gradients that generate variation in behavior, physiology and life-history. Because rates of physiological processes are very sensitive to temperature, cold environments are thought to favor genotypes that have relatively high capacities for growth despite environmental constraints. Two different adaptive responses can occur: (1) mothers in colder environments can allocate more energy to each offspring, or (2) offspring in colder environments make more efficient use of available resources. In this study, I examined both maternal adaptations and embryonic adaptations to environmental temperature. Evidence of maternal adaptations was assessed by examining the relationship between egg size and …

A New Species Of Oryzomys (Rodentia: Muridae) From An Isolated Pocket Of Cerrado In Eastern Bolivia, Daniel M. Brooks, R. Julieta Vargas M., Teresa Tarifa, Hugo Aranibar, José Manuel Rojas
University of Nebraska State Museum: Mammalogy Papers
Reliable characterization of a species is an essential step toward eventual reconstruction of phylogenetic alliances among related taxa (Musser et al. 1998). Although characterization of species within the genus Oryzomys has met with some confusion in the past, significant work has taken place to help better define specific limits within this group (Musser et al. 1998; Bonvicino and Moreira 2001; Langguth and Bonvicino 2002).
In spite of several recent surveys performed in the eastern Bolivian Panhandle (Emmons 1993; Taber et al. 1997; Brooks et al. 2002), our knowledge of the mammalian fauna in this region is still incomplete, and further …
A Staging Sequence And Analysis Of Growth In Postovipositional Embryos Of Lamprophis Fulignosus, Angela Renee Vogel Rivera
A Staging Sequence And Analysis Of Growth In Postovipositional Embryos Of Lamprophis Fulignosus, Angela Renee Vogel Rivera
Biological Sciences Theses & Dissertations
The brown house snake, Lamprophis fuliginosus, is a small, oviparous snake found throughout much of Africa. This lamprophiine colubrid reproduces rapidly; captive females can lay clutches every three to four months for a sustained period. Thus, L. fuliginosus is an excellent model for developmental studies requiring large numbers of embryos. In addition, the embryos of oviparous species are more suitable for some procedures than are those of viviparous forms. The most widely used system for staging embryonic snakes was developed for the common gartersnake, Thamnophis sirtalis, a viviparous natricine colubrid (Zehr, 1962). Based on the examination of 135 …
