This large (9 x 12 inches) and sumptuously illustrated book details the life and biological contributions of John Townsend, one of the earliest biologists after Lewis and Clark (1804) and Prince Maximilian (1832) to visit what is now Nebraska, preceding John J. Audubon's visit (1843) by nearly a decade. Townsend ascended the upper Platte Valley during an 1834 …

2007 Nebraska Midwinter Bald Eagle Survey, Joel E. Jorgensen, Sarah E. Rehme

Nebraska Bird Review

Bald and Golden Eagles are species of conservation concern that regularly winter in Nebraska (Sharpe et al. 2001). The Nebraska Game and Parks Commission (NCJPC) has conducted an annual statewide Midwinter Eagle Survey (MWS) since 1980. The Nebraska MWS is done in conjunction with a national survey coordinated by the U.S. Geological Survey. The purpose of the MWS is to determine the number and distribution of eagles wintering in Nebraska. Here we present results from the 2007 Nebraska MWS.

Endangered Species Responses To Natural Habitat Declines: Nebraska’S Interior Least Terns (Sternula Antillarum Athalassos) And Piping Plovers (Charadrius Melodus) Nesting In A Human-Created Habitat, Mary Bomberger Brown, Joel G. Jorgensen, Sarah E. Rehme

Nebraska Bird Review

Formerly, state and federally endangered Interior Least Terns (Sternula antillarum athalassos) and state and federally threatened Piping Plovers (Charadrius melodus) nested on sandbars in rivers as well as on other sandy beach habitat (Hardy 1957; Haig 1992; Kirsch 1992; Ziewitz et al. 1992; Thompson et al. 1997). In Nebraska, the birds primarily used sandbars in the Platte, Loup, Elkhorn, Niobrara, and Missouri rivers (Sharpe et al. 2001). These sandbars were created and maintained by river flow and regular flooding events. Despite the frequent scouring, reshaping, and relocation of the sandbars, nesting habitat was consistently available to …

Sequences, Annotation And Single Nucleotide Polymorphism Of The Major Histocompatibility Complex In The Domestic Cat, Naoya Yuhki, James C. Mullikin, Thomas W. Beck, Robert M. Stephens, Stephen J. O'Brien

Biology Faculty Articles

Two sequences of major histocompatibility complex (MHC) regions in the domestic cat, 2.976 and 0.362 Mbps, which were separated by an ancient chromosome break (55–80 MYA) and followed by a chromosomal inversion were annotated in detail. Gene annotation of this MHC was completed and identified 183 possible coding regions, 147 human homologues, possible functional genes and 36 pseudo/unidentified genes) by GENSCAN and BLASTN, BLASTP RepeatMasker programs. The first region spans 2.976 Mbp sequence, which encodes six classical class II antigens (three DRA and three DRB antigens) lacking the functional DP, DQ regions, nine antigen processing molecules (DOA/DOB, DMA/DMB, TAPASIN, and …

A Review Of Species In The Genus Rhopalias (Rudolphi, 1819), Terry R. Haverkost, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Currently, there are 6 recognized species in the genus Rhopalias. These parasites are found in the small intestines of numerous species of marsupials throughout North and South America. Small mistakes in various classical taxonomic works have given rise to recent and numerous misidentifications of these species. In this work, we examine a total of 99 specimens across all species from museum collections in an attempt to determine informative taxonomic characters to distinguish these species. Despite confusion in the literature, accurate identification of these species can be achieved by observing the presence or absence of oral and flanking spines anterior …

The Spatial Memory Of African Elephants (Loxodonta Africana): Durability, Interference, And Response Biases, Robert H.I. Dale

Scholarship and Professional Work - LAS

Women and elephants never forget an injury.

-Saki (H. H. Munro), "Reginald on besetting sins," in Reginald (1904)

I am not sure whether the satirist H. H. Munro believed Saki's claim, although it may well be true (at least with regard to elephants). This chapter will examine some characteristics of elephant memory more systematically than did Saki.

In general, it is to an animal's advantage to remember some aspects (usually the stable features) of a situation for long periods and to remember other aspects (usually the unstable features) only temporarily. Consistent with recent arguments questioning the value of cognitive constructs …

Influential Parasites: Importance Of Haemosporidian Parasite Infection In The White-Throated Sparrow, Amanda P. Jamison

All-Inclusive List of Electronic Theses and Dissertations

The study of parasite-mediated selection, as originally postulated by Hamilton and Zuk ( 1982) in birds is an area of intense study as it allows us to test the significance of the relationship between host and parasite. Recent developments of resistance to treatments in humans for parasite induced disease, creates a place for this important research and emphasizes the need to find the connections and interactions in this relationship between ecology and infectious disease. The development of new molecular techniques has made the study of parasitism in birds and mammals easier and provides an efficient sensitive . methodology to detect …

Development Of A Novel Fouling Deterrence Strategy By Understanding The Efect Of Noradrenaline On The Cells Of Eastern Oyster, Crassostrea Virginica And Cypris Larve Of The Striped Barnacle Balanus Amphitrite, Neeraj Gohad

All Dissertations

ABSTRACT

The focus of this study was to understand and evaluate the effect of noradrenaline (NA) on two prominent fouling marine invertebrates, the Eastern Oyster, Crassostrea virginica and the Striped Barnacle, Balanus amphitrite for the purpose of developing a novel fouling deterrence strategy.
To understand the effect of NA at a cellular level the immune cells (hemocytes) of C. virginica were chosen as representative molluscan cells. Upon stimulation with 10 micro-molar of noradrenaline ~4% hemocytes of C. virginica labeled positive for the beta-adrenergic receptor (beta-AR). Upon NA stimulation the beta-AR positive cells formed cell-cell synapses and apoptosis was detected in …

Characterization Of Soluble Matrix From Molluscan Shell With An Emphasis On Two Major Phosphoproteins From The Eastern Oyster, Crassostrea Virginica, Mary Johnstone

All Dissertations

The soluble organic matrix (SM) extracted from the shell of the Eastern oyster, Crassostrea virginica was analyzed to identify the constituent proteins and their structures. Two acidic proteins with estimated molecular weights of 48 and 55 kD were isolated and determined to have highly related structures. Both proteins are comprised primarily of aspartate, serine, and glycine which represent nearly 90% of the total amino acids. Studies indicate that both proteins are phosphorylated and have estimated isoelectric points in the range of 3 to 5. Evidence suggests that poly-aspartate and poly-serine domains are present in the 48 kD protein. Amino terminal …

A New Reproductive Mode In The Genus Melanzophryniscus Gallardo, 1961 (Anura: Bufonidae) With Description Of A New Species From The State Of Paraná, Brazil, José A. Langone, Magno V. Segallo, Marcos Bornschein, Rafael O. De Sá

Biology Faculty Publications

A new species of bufonid toad of the genus Melanophryniscus is described from a mountaintop that is part of the Serra do Mar in the northeastern State of Paraná, Brazil. Melanophryniscus alipioi sp. nov. is distinguished from other known species by its uniformly dark brown dorsal color and a unique breeding site. The new species reproduces in bromeliads, a reproductive mode previously unknown for this genus. This species might be susceptible to current habitat lost.

Measuring Bite Force In Small Mammals With A Piezo-Resistive Sensor, Patricia W. Freeman, Cliff A. Lemen

University of Nebraska State Museum: Mammalogy Papers

We tested the use of piezo-resistive force sensors to measure bite force in small mammals. These force sensors are thin (less than 1 mm) and can be used to measure forces up to 4,500 N. A battery-operated unit, ideal for field research, can be built easily and inexpensively. We tested this sensor in the laboratory and in the field on a variety of small mammals. Although our results indicate that the sensor is somewhat less accurate (coefficient of variation = 4%) than a conventional load cell, the small size and ease of use of the piezo-resistive detector is highly desirable. …

Biology Faculty Articles

Background:

Over the past years a variety of host restriction genes have been identified in human and mammals that modulate retrovirus infectivity, replication, assembly, and/or cross-species transmission. Among these host-encoded restriction factors, the APOBEC3 (A3; apolipoprotein B mRNA-editing catalytic polypeptide 3) proteins are potent inhibitors of retroviruses and retrotransposons. While primates encode seven of these genes (A3A to A3H), rodents carry only a single A3 gene.

Results:

Here we identified and characterized several A3 genes in the genome of domestic cat (Felis catus) by analyzing the genomic A3 locus. The cat genome presents one A3H gene and three …

First Nebraska Record For The Royal Tern (Sterna Maxima) And A Review Of Regional Records, Sarah E. Rehme, Thomas E. Labedz, Janis Paseka

Nebraska Bird Review

On the afternoon of 8 Sept 2007, Don and Janis Paseka discovered a large tern on the causeway that separates Lake North from Lake Babcock, north of Columbus, Platte County, Nebraska. The causeway consists of a road next to Lake North and a low cement wall next to Lake Babcock. They observed the tern at approximately 1630 CDT standing on the low wall, on the west side of the causeway. The tern remained standing on the wall as they drove to within 15 feet and photographed it. The tern was standing with its wings drooping (Photo 1), and the fact …

Winter Field Report, December 2007 To February 2008, W. Ross Silcock

Nebraska Bird Review

This winter in Nebraska was much colder on average than the few previous winters, not so much because of low temperatures, but a lack of warmer days. This kept water bodies frozen most of the winter, with far fewer than usual midwinter water-bird records. Surprisingly, though, passerines, including some surprises, were able to brave the coolness. Notable were three species of wood-warblers; although Yellow-rumped Warblers winter to some extent in the southeast, 9 of the 21 total February records for the species have come in the last two winters. The others were not unprecedented for Nebraska, and are known to …

2007–2008 Christmas Bird Counts In Nebraska

Nebraska Bird Review

The 2007-08 Christmas Bird Count (CBC) period will be remembered for snow cover and cold temperatures. More counts than usual were postponed due to weather. The average high temperature on count day this year was 28°F and the low was 12°F, both of which are 5-10° colder than any count day average since 2000-01. Only three counts made it above freezing during the course of the day. Snow was also a problem, and although only two circles recorded precipitation on the day of the count, snow cover and ice from earlier storms resulted in stuck vehicles, arduous walking, and inaccessible …

Ecology Of The Missouri River: Missouri River Creel Survey, Bellevue Bridge To Camp Creek, 31 March Through 12 October 2007. Supplement I, Gerald Mestl

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

This report describes Missouri River activities and results related to a channelized Missouri River creel survey conducted from 29 March through 10 October 2003. This is the fourth of a planned annual creel survey to be conducted on alternating sections of the channelized Missouri River to measure changes in recreational fishing activity, especially those changes due to large scale habitat restoration efforts. Future reports will contain additional analyses of these data.

Anglers spent over 30,000 hours fishing the Missouri River from Camp Creek (rk 883.5) to the Kansas state line (rk 790.2) during the survey period. Effort peaked during the …

The Adaptive Evolution Of The Mammalian Mitochondrial Genome, Rute R. Da Fonseca, Warren E. Johnson, Stephen J. O'Brien, Maria J. Ramos, Agostinho Antunes

Biology Faculty Articles

Background

The mitochondria produce up to 95% of a eukaryotic cell's energy through oxidative phosphorylation. The proteins involved in this vital process are under high functional constraints. However, metabolic requirements vary across species, potentially modifying selective pressures. We evaluate the adaptive evolution of 12 protein-coding mitochondrial genes in 41 placental mammalian species by assessing amino acid sequence variation and exploring the functional implications of observed variation in secondary and tertiary protein structures.

Results

Wide variation in the properties of amino acids were observed at functionally important regions of cytochrome b in species with more-specialized metabolic requirements (such as adaptation to …

Terrapene Ornata (Ornate Box Turtle) Predation On Cliff Swallows, Mary Bomberger Brown, Charles R. Brown

School of Natural Resources: Faculty Publications

During a 25-year study of Cliff Swallows (Petrochelidon pyrrhonota) in southwestern Nebraska, we observed Terrapene ornata prey, or attempt to prey, on swallows. On one occasion as large numbers of birds flushed and hit the net, the weight of the birds pulled the net down to ground level. One T. ornata, which was seen regularly at the colony, approached one adult Cliff Swallow that was very low in the net and killed it by biting and eating its head. After killing the bird, the turtle walked away carrying the head.

A Simple Morphological Predictor Of Bite Force In Rodents, Patricia W. Freeman, Cliff A. Lemen

University of Nebraska State Museum: Mammalogy Papers

Bite force was quantified for 13 species of North American rodents using a piezo-resistive sensor. Most of the species measured (11) formed a tight relationship between body mass and bite force (log 10(bite force) = 0.43(log 10(body mass)) + 0.416; R² > 0.98). This high correlation exists despite the ecological (omnivores, grazers and more carnivorous) and taxonomic (Cricetidae, Heteromyidae, Sciuridae and Zapodidae) diversity of species. Two additional species, Geomys bursarius (Geomyidae) and a Sciurus niger (Sciuridae), bit much harder for their size. We found a simple index of strength based on two measurements of the incisor at the level of …

Scale-Dependent Habitat Use By Fall Migratory Birds: Vegetation Architecture, Floristics, And Geographic Consistency, Jill Deppe, John Rotenberry

Faculty Research & Creative Activity

Animal habitat selection is a central focus of ecology and conservation biology. Understanding habitat associations in migratory animals is particularly complicated because individuals have variable habitat requirements during the annual cycle, across their geographic range, along migratory routes, and at multiple spatial scales. We studied habitat associations of 16 fall Nearctic–Neotropical migratory land birds at two spatial scales at a stopover site along the northern Yucatan coast to examine scale-dependent habitat use, identify proximate cues shaping birds' distributions, and evaluate similarities in habitat use between our tropical stopover site and temperate sites. We addressed scale-dependent habitat associations in two ways, …
