The Second Nebraska Breeding Bird Atlas, Wayne J. Mollhoff, Bulletin Of The University Of Nebraska State Museum, Vol. 29, 2016 [Book Review], W. Ross Silcock Jun 2016

The Second Nebraska Breeding Bird Atlas, Wayne J. Mollhoff, Bulletin Of The University Of Nebraska State Museum, Vol. 29, 2016 [Book Review], W. Ross Silcock

Nebraska Bird Review

As suggested by its title, this book (“Second Atlas”) presents the results of a follow-up to the first Nebraska breeding bird atlas, The Nebraska Breeding Bird Atlas 1984–89 (“First Atlas”), also authored by Wayne Mollhoff. In this Second Atlas, Mollhoff acknowledges the foresight of John J. Dinan, Nongame Bird Program Manager at Nebraska Game and Parks Commission during the time of the First Atlas, in working toward a “follow-up project.” As Mollhoff says in the foreword to the Second Atlas, "His persistence in pursuing that goal ultimately led to the current project.”

The best feature of the Second Atlas is …


Gyrfalcon In Boyd County, Nebraska, Mark A. Brogie, David Heidt Jun 2016

Gyrfalcon In Boyd County, Nebraska, Mark A. Brogie, David Heidt

Nebraska Bird Review

Gyrfalcon (Falco rusticolus) is considered in Nebraska to be a "rare casual winter visitor statewide" (Sharpe et al. 2001). Since 1990, there has been only one NOURC (Nebraska Ornithologists' Union Records Committee) accepted record (Class III) for Gyrfalcon in Nebraska (Jorgensen 2003). This bird was a gray morph adult observed below Keystone Dam, Keith Co., 01 January 2001 (Silcock 2001). Nebraska has no April dates for Gyrfalcon, although South Dakota has several April records: 10 Apr 2001, Jones Co., and 23 Apr 1955, Pennington Co., (Tallman et al. 2002). Additionally, an immature Gyrfalcon was photographed 5 April 2010 …

Spring Field Report, March 2016 To May 2016, W. Ross Silcock Jun 2016

Spring Field Report, March 2016 To May 2016, W. Ross Silcock

Nebraska Bird Review

In contrast to the fairly routine spring of 2015, this year saw an almost unbelievable parade of early arrivals. About 49 species, including virtually all taxonomic groups, had arrival dates at the early end of expected arrival dates, and a few species set record early dates. Notable early birds were Calidris shorebirds, flycatchers, and swallows, species which depend on available insect and pond-edge life, suggesting that organisms are "waking up" earlier than in previous years, helped, of course, by the mild 2015–2016 winter. On the other hand, there was only one late species: Purple Finch, which remained into mid-May at …


Bone-Associated Gene Evolution And The Origin Of Flight In Birds, Joao P. Machado, Warren E. Johnson, M. Thomas P. Gilbert, Guojie Zhang, Erich D. Jarvis, Stephen J. O'Brien, Agostinho Antunes May 2016

Bone-Associated Gene Evolution And The Origin Of Flight In Birds, Joao P. Machado, Warren E. Johnson, M. Thomas P. Gilbert, Guojie Zhang, Erich D. Jarvis, Stephen J. O'Brien, Agostinho Antunes

Biology Faculty Articles

Background

Bones have been subjected to considerable selective pressure throughout vertebrate evolution, such as occurred during the adaptations associated with the development of powered flight. Powered flight evolved independently in two extant clades of vertebrates, birds and bats. While this trait provided advantages such as in aerial foraging habits, escape from predators or long-distance travels, it also imposed great challenges, namely in the bone structure.

Results

We performed comparative genomic analyses of 89 bone-associated genes from 47 avian genomes (including 45 new), 39 mammalian, and 20 reptilian genomes, and demonstrate that birds, after correcting for multiple testing, have an almost …


Development Of A Biofilm Model For Evaluating Poultry Drinking Water Sanitation Procedures, Pramir Maharjan May 2016

Development Of A Biofilm Model For Evaluating Poultry Drinking Water Sanitation Procedures, Pramir Maharjan

Graduate Theses and Dissertations

Enclosed water system has created a minimal sanitation focus leading to biofilm issues which are a source of flock health challenges. A series of in vitro tests were conducted to evaluate biofilm growth on polyvinylchloride (PVC) surfaces when exposed to treated/untreated water sources (test water) that are typically supplied in commercial barns. PVC test coupons (15.16 cm2) were immersed in test water in beakers to grow biofilm. Test water supplies were characterized for microbial, mineral and pH content. Temperature of test water was set at 90 °F (32.2 ᵒC) on d1 and then dropping 1°F each day over 7-day period …


A Molecular Approach To Understanding The Effects Of Original-Xpc On The Modulation Of The Cecal Microbiota And The Survival Of Salmonella In The Poultry Host, Stephanie Roto May 2016

A Molecular Approach To Understanding The Effects Of Original-Xpc On The Modulation Of The Cecal Microbiota And The Survival Of Salmonella In The Poultry Host, Stephanie Roto

Graduate Theses and Dissertations

Salmonella is a foodborne pathogen commonly associated with poultry products; the economic burden to the U.S. is estimated to be approximately $693 million (without factoring in contaminated eggs). Recently, there has been pressure to withdraw sub-therapeutic levels of antibiotics (also known as antibiotic growth promoters; AGP) from poultry due to concern over antibiotic-resistant bacteria spreading to the human population. Therefore, various feed additives have been researched for their ability in providing protection against harmful pathogens and their potential growth promoting effects, both of which were attributes of poultry treated with AGP. This thesis consists of a comprehensive literature review that …


Use Of A Blunt Version Of Meullenet-Owens Razor Shear To Analyze Meat Qualities Of Broilers With Woody Breast Myopathy And Reared To Various Ages, Famous Lue Yang May 2016

Use Of A Blunt Version Of Meullenet-Owens Razor Shear To Analyze Meat Qualities Of Broilers With Woody Breast Myopathy And Reared To Various Ages, Famous Lue Yang

Graduate Theses and Dissertations

Broiler breast meat tenderness is an important meat quality attribute. There has been an increase in incidences of woody breast along with white striping as meat quality defects. These defects have been found to negatively impact meat qualities of broiler breast fillets. Woody breast can be classified by the degree of hardness into normal (NORM) and severe (SEV). The Meullenet-Owens Razor Shear (MORS) method was developed to assess broiler meat tenderness and a blunt version (BMORS) has been reported to be more sensitive at higher degrees of toughness. The present study was intended to determine the effect of age, debone …


Proteomic Characterization Of Eggshell Membranes And Their Effect On Poultry Physiology And Immunity, Sarbjeet Kaur Makkar May 2016

Proteomic Characterization Of Eggshell Membranes And Their Effect On Poultry Physiology And Immunity, Sarbjeet Kaur Makkar

Graduate Theses and Dissertations

The use of antibiotics in poultry growth and disease control has led to antibiotics resistant problem in human beings, which is a big concern among consumers. With the necessity for judicious use of antibiotics in poultry production, alternative strategies to improve disease resistance in poultry production are necessary. The research is more inclined towards using the natural products available to grow healthier and antibiotic free meat animals. In the context of exploring natural and sustainable resource of alternative to antibiotics, the biochemical milieu of eggshell membranes (ESM) were analyzed by using mass spectrometry techniques including matrix assisted laser desorption ionization …


Evaluation And Selection Of A Bacillus Based Direct-Fed Microbial Candidate For In Situ Enzyme Production To Improve Gut Health Integrity, Bone Quality And Growth Performance In Poultry, Juan David Latorre Cardenas May 2016

Evaluation And Selection Of A Bacillus Based Direct-Fed Microbial Candidate For In Situ Enzyme Production To Improve Gut Health Integrity, Bone Quality And Growth Performance In Poultry, Juan David Latorre Cardenas

Graduate Theses and Dissertations

During the last decade, the increasing interest in renewable energy sources has been changing the distribution of corn utilization from human and animal consumption to biofuel production, leading to a continuous rise in feed costs of livestock diets. Therefore, alternative feed ingredients such as distillers dried grains with solubles (DDGS), as well as cereals like wheat, barley, and sorghum have become part of the feed matrix to maintain or reduce production costs. However, these raw materials often contain a higher concentration of antinutritional factors in comparison to corn, including non-starch polysaccharides (NSP) which increase digesta viscosity and reduce nutrient absorption …


Meat Quality And Sensory Analysis Of Broiler Breast Fillets With Woody Breast Muscle Myopathy, Jessica Solo May 2016

Meat Quality And Sensory Analysis Of Broiler Breast Fillets With Woody Breast Muscle Myopathy, Jessica Solo

Graduate Theses and Dissertations

Recently, the poultry industry has encountered an emerging muscle myopathy known as woody breast (WB), which is characterized by hardness throughout the Pectoralis major muscle. Two experiments were performed to assess sensory characteristics and acceptability of WB meat and to determine the effect of broiler age on meat quality factors in varying severities of WB. Fillets were categorized as normal (NORM), moderate (MOD), or severe (SEV) WB. In Experiment 1 (Exp. 1), descriptive (n=9 trained panelists) and consumer (n=74 panelists) sensory analysis was conducted with NORM and SEV fillets at hot and cold serving temperatures (HOTNORM, COLDNORM, HOTSEV, COLDSEV). In …


Cfd Model For Ventilation In Broiler Holding Sheds, Christian Heymsfield May 2016

Cfd Model For Ventilation In Broiler Holding Sheds, Christian Heymsfield

Biological and Agricultural Engineering Undergraduate Honors Theses

Broiler production in Arkansas was valued at over $3.6 billion in 2013 (University of Arkansas Extension of Agriculture). Consequently, improvement in any phase of the production process can have significant economic impact and animal welfare implications. From the time poultry leave the farm and until they are slaughtered, they can be exposed to harsh environmental conditions, both in winter and in summer. After road transportation, birds are left to wait in holding sheds once they arrive at the processing plant, for periods of approximately 30 minutes to two hours. This project was interested in this holding shed waiting time during …


Population And Morphological Changes In American Kestrels Through Space And Time, Teresa E. Ely Apr 2016

Population And Morphological Changes In American Kestrels Through Space And Time, Teresa E. Ely

School of Biological Sciences: Dissertations, Theses, and Student Research

A once common raptor, the American kestrel (Falco sparverius) has experienced population declines in the last two decades throughout North America. Many hypotheses exist about the decline, including mortality from West Nile virus, rodenticide poisoning, climate change, an increase in predators, and core habitat loss or degradation, which could influence food availability. Food availability is key to raptor survival and reproduction, and changes in food availability throughout the year can have lifelong effects on size and body condition. Here we examine how morphology, specifically mass and wing chord, has changed at seven migration sites throughout North America as …


Is Diet Selection By Greater Sage-Grouse Influenced By Biomass Availability Or Toxins?, Jacqueline Peña, Marcella Fremgen Apr 2016

Is Diet Selection By Greater Sage-Grouse Influenced By Biomass Availability Or Toxins?, Jacqueline Peña, Marcella Fremgen

McNair Scholars Research Journal

Foraging herbivores must meet nutritional requirements by not only finding enough plant biomass to consume, but also finding plants with high protein content and low concentrations of potentially toxic plant secondary metabolites (PSMs). Greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) are sagebrush obligate herbivores that consume relatively high concentrations of PSMs. To meet their nutritional needs and avoid ingesting high amounts of PSMs, sage-grouse may select species of sagebrush for food that have lower concentrations of PSMs than a more abundant species with higher concentration of PSMs. Diet selection by sage-grouse may also be driven by chemical factors at finer scales …


Avifaunal Community Composition In A Tropical Forest Corridor: A Case Study From The Atherton Tableland, North Queensland, Don Jones Apr 2016

Avifaunal Community Composition In A Tropical Forest Corridor: A Case Study From The Atherton Tableland, North Queensland, Don Jones

Independent Study Project (ISP) Collection

Bird communities in tropical forest ecosystems are highly threatened by habitat loss and fragmentation. Replanted corridors connecting isolated forest remnants are a popular method of ameliorating certain negative impacts of habitat fragmentation. Such linkages can theoretically facilitate greater dispersal, increase gene flow, and reduce the risk of local extinctions in forest birds. However, relatively few studies have examined the utilization of reforested corridors by birds, and little hard data exists to support claims that this type of resource and time intensive project is the best use of often scarce funding for conservation. This study examined the avifaunal community present in …


Gene Expression Response To Heat Stress In Two Broiler Lines, Jibin Zhang, Carl J. Schmidt, Susan J. Lamont Mar 2016

Gene Expression Response To Heat Stress In Two Broiler Lines, Jibin Zhang, Carl J. Schmidt, Susan J. Lamont

Jibin Zhang

The fast growth rate and increased body weight of modern broilers makes them susceptible to heart failure and sensitive to heat stress. To find the genetic causes of these problems, gene expression was measured in hearts of two broiler lines that differed in their response to heat stress. Each line was separated into two groups that were kept under heat stress or at ambient temperature. The comparison of gene expression between the two lines and heat treatments suggests that expression of 325 genes were significantly changed in modern broilers under heat stress, while only 3 genes changed their expression in …

2015–2016 Christmas Bird Counts, Don Paseka Mar 2016

2015–2016 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fifteen counts were held during the 2015–16 Christmas Bird Count season, which is one more than last season when the Harrison count was canceled. The Grand Island count was held on December 12, two days prior to the start of the officially sanctioned CBC time slot, but its results are included in this discussion.

Ten of the counts were done on or before December 22 under mild conditions with little snow cover and mostly to entirely open water. While the weather became more seasonable toward the end of the period, it was still fairly benign. As a result, most of …

Winter Field Report, December 2015 To February 2016, W. Ross Silcock

Nebraska Bird Review

As has been the trend in recent years, many species are lingering later in fall and even arriving earlier in spring. Along with lingering birds, mid-winter and overwintering records have increased. This winter was phenomenal in this respect, especially in that records were across the board in terms of species, suggesting that water conditions have moderated (more open water) and temperatures in general have also (passerines). Unprecedented records included first wintering White-winged Scoter and first Jan or Feb record of Orange-crowned Warbler. Second or third such records were set by Blue-winged Teal, Surf Scoter, Ruddy Duck, Eared Grebe, Greater Yellowlegs, …

Eight Years Of Bird Banding In Nebraska’S Chadron State Park, Josh Lefever Mar 2016

Eight Years Of Bird Banding In Nebraska’S Chadron State Park, Josh Lefever

Nebraska Bird Review

Each autumn since 2008, the Bird Conservancy of the Rockies has sent a trained biologist to capture, band, and collect data on the birds that make use of the Pine Ridge region on their journey south. Eight years of mist-netting at Chadron State Park, in the heart of the Pine Ridge, has given insights into the unique assemblage of birds found there, and how alteration by fire can affect birds' use of the habitat. The Chadron State Park banding station is located on a hillside near the west edge of the park, with an overstory of Ponderosa Pines and a …


Swans: Their Biology And Natural History, Paul A. Johnsgard Feb 2016

Swans: Their Biology And Natural History, Paul A. Johnsgard

Zea E-Books Collection

The seven species of swans of the world are an easily and universally recognized group of waterfowl, which have historically played important roles in the folklore, myths and legends in many of the world’s cultures. Among the largest of all flying birds, they have also almost universally been used as symbols of royalty, grace and beauty, and largely for these reasons swans have only rarely been considered acceptable as targets for sport hunting. Swans occur on all the continents except Africa, although most species are associated with the temperate and arctic zones of North America and Eurasia. Among birds, swans …


Flight Mechanics And Control Of Escape Manoeuvres In Hummingbirds. I. Flight Kinematics, Bo Cheng, Bret W. Tobalske, Donald R. Powers, Tyson L. Hedrick, Susan M. Wethington, George T.C. Chiu, Xinyan Deng Jan 2016

Flight Mechanics And Control Of Escape Manoeuvres In Hummingbirds. I. Flight Kinematics, Bo Cheng, Bret W. Tobalske, Donald R. Powers, Tyson L. Hedrick, Susan M. Wethington, George T.C. Chiu, Xinyan Deng

Faculty Publications - Department of Biological & Molecular Science

Hummingbirds are nature’s masters of aerobatic manoeuvres. Previous research shows that hummingbirds and insects converged evolutionarily upon similar aerodynamic mechanisms and kinematics in hovering. Herein, we use three-dimensional kinematic data to begin to test for similar convergence of kinematics used for escape flight and to explore the effects of body size upon manoeuvring. We studied four hummingbird species in North America including two large species (magnificent hummingbird, Eugenes fulgens, 7.8 g, and blue-throated hummingbird, Lampornis clemenciae, 8.0 g) and two smaller species (broad-billed hummingbird, Cynanthus latirostris, 3.4 g, and black-chinned hummingbirds Archilochus alexandri, 3.1 g). Starting from a steady hover, …


Prevalence And Diversity Of The Haemosporidian Blood Parasite Leucocytozoon In Sub-Saharan African Birds, Heather Skeen Jan 2016

Prevalence And Diversity Of The Haemosporidian Blood Parasite Leucocytozoon In Sub-Saharan African Birds, Heather Skeen

Master's Theses

Our knowledge of avian Haemosporidian parasites has increased dramatically with the advent and increased used of molecular technologies. Yet Leucocytozoon, a common avian parasite, remains relatively understudied. Haemosporidian parasite diversity and prevalence has been shown to be dependent on several factors, including host family and habitat, on a microecological scale. In this study I screened 3,375 birds from sub-Saharan Africa for the presence of Leucocytozoon and demonstrate that the patterns of prevalence and diversity continue at a macroecological scale. Using molecular data, I found that the prevalence of Leucocytozoon varied between sampling areas from 3.9% to 62.64% and the diversity …
