Oriole Consumption Of Grape Jelly, Gary Lingle

Nebraska Bird Review

It is well known that several species of orioles are attracted to grape (Vitis sp.) jelly. A few years ago I began “feeding” grape jelly to orioles in my yard in Buffalo County. Both Baltimore Orioles (Icterus galbula) and, to a lesser extent, Orchard Orioles (Icterus spurius) frequented my feeder upon their arrival in early May and fed daily until the red mulberries (Morus rubra) ripened and nesting had commenced prior to mid-June. At that time visitation to my feeder plummeted from a high of 1.5 birds per minute to 0 .1 birds …

Spring Field Report, March 2015 To May 2015, W. Ross Silcock

Nebraska Bird Review

This was a largely uneventful spring in terms of major events, as most species stayed within their ranges and movement timing parameters. There are always a few stochastic exceptions, but no clear pattern of, for example, early arrival dates was discernible. However, several interesting situations came to light, and there were a few rarities detected. A Couch’s Kingbird in Sarpy Co was well described but awaits a determination by the Nebraska Ornithologists' Union Records Committee as to whether the evidence is strong enough to add this species to the Official State Bird List. Other exciting finds were a wintering Brown …

Book Review [Of At Home And At Large In The Great Plains: Essays And Memories], Janis Paseka

Nebraska Bird Review

Nebraska birders may remember reading some of the 14 essays published in this book, since they appeared previously in Prairie Fire, the monthly Great Plains public policy newspaper. Topics of the short and engaging essays range from changing bird life to outstanding birding areas to conservation in the Great Plains. We read about sediment deposits, the “gifts of glaciers past,” which were left by retreating rivers of ice thousands of years ago and resulted in the creation of the prairie potholes so important now to our waterfowl and wading birds. One essay marvels at the variety of animal skeletons, including …

Phylogeography Of Southeast Asian Flying Foxes (Chiroptera: Pteropodidae: Pteropus), Susan Man Shu Tsang

Dissertations, Theses, and Capstone Projects

Flying foxes (Pteropus) are a genus of Old World fruit bats that are important seed dispersers and pollinators for plants native to the 200,000+ islands in Southeast Asia, yet they are some of the most poorly known bats in the world. They comprise some of the largest known bat species, and are morphologically relatively conserved on the genus level. Pteropus is the most species-rich genus within Pteropodidae, though the origin for this diversity remains incompletely understood. In Chapter 1, I discuss the importance of Pteropus to the ecosystem and as reservoir hosts. In Chapter 2, a molecular phylogeny is presented …

How Access To Plant & Animal Books Affects Participation In Conservation Activities, Dustin Ingram, Hassnaa Ingram

Library Philosophy and Practice (e-journal)

Abstract

Public libraries are an important resource for communities. Access to plant and animal books impacts a communities’ ability to learn about their environment. In this study, the number of plant and animal books available to people through local libraries in northern Kentucky, and neighboring counties in Ohio and Indiana were counted and a survey assessing one’s preferences and likeliness to participate in conservation activities was distributed to local residents. Based on the collected data, a statistically significant relationship (p < 0.05) was found between access to plant and animal books available at local libraries and the likelihood of people to participate in conservation activities. Further analysis was performed between the total number of shelved plant and animal books at local libraries, the total number of shelved juvenile plant and animal books and the shelved adult plant and animal books, and the total number of plant and animal books in libraries compared to the local household income and number of households near a library. This study found that people that read books about plants and animals were more likely to participate in conservation activities associated with their book preference. This study also found that people living in low-income communities with fewer households are less likely to participate in plant and animal conservation, as compared to higher-income communities with a higher number of households. Additionally, this study found that lower income areas have fewer plant and animal books on the library shelves than higher income areas. Consequently, study results suggest that if more plant and animal books were made available to low-income areas and areas of biological importance through libraries, people may be more likely to conserve the wildlife around them.

The Suitability Of Habitats And The Effects Of Human Activities In Osupuko And Olepolos Wildlife Sanctuaries On Maasai Giraffes, Sydney P. Davis

Undergraduate Honors Theses

Habitat quality and resource availability within wildlife dispersal areas in the Amboseli ecosystem are experiencing degradation due to pastoralism and agriculture by humans, which negatively affects the wildlife species that utilize these dispersal areas. Maasai giraffes are a common species that utilize these areas, but information on how human activities and the presence of domestic livestock affects the Maasai giraffe is limited. This study was conducted in two wildlife sanctuaries: Osupuko and Olepolos. Habitat condition assessment was done to determine the quality of habitats found within each sanctuary. The Point-Centered Quadrat Method was used to determine the number of five …

Characterization And Transplantation Of Felid Spermatogonial Stem Cells, Robin H. Powell

LSU New Orleans Theses and Dissertations

Spermatogonial stem cells (SSC) self-renew and differentiate into spermatozoa throughout the life of the male. SSC transplantation is a potential method for the propagation of genetically important males. These cells have been isolated in different mammalian species using specific cell surface markers, but not in felines.

The goal of this study was to explore a relevant strategy for conservation of endangered felids by characterizing domestic cat (Felis catus) SSCs and assessing their ability for self-renewal after transplantation. Firstly, SSC and pluripotent surface markers, identified in non-feline species, were tested for expression in mixed germ cells from adults by …

Distributional Expansion Of The Hispid Cotton Rat (Sigmodon Hispidus) Into Dawson County, Nebraska, Jennifer D. Frisch, Keith Geluso, Joseph T. Springer

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

In the last century, the Hispid Cotton Rat (Sigmodon hispidus) has moved northward in central parts of the United States, reaching Nebraska in the late 1950s. Recent surveys demonstrate Hispid Cotton Rats inhabit counties across southern parts of Nebraska south of the Platte River. Herein, we report on captures of S. hispidus from a new county (Dawson County), its seasonal occurrence at our study site, and the first known record of the Hispid Cotton Rat north of channels of the Platte River. Our captures represent one of the northern-most records in Nebraska.

Habituation To Auditory Stimuli By Captive African Elephants (Loxodonta Africana), Sarah Elizabeth Goodyear

Masters Theses & Specialist Projects

Elephants are cognitive species that exhibit many types of learning. Associative, social, and insight learning have been investigated with elephants, but one of the simplest forms, habituation, has not. As an individual learns that a stimulus is neither harmful nor beneficial, it will decrease its response to the stimulus through the process of habituation. Elephants possess a well-developed sensory system and may habituate to stimuli that could be used for enrichment and/or management. The aim of this study was to examine the habituation process of elephants in response to repeated presentations of two auditory stimuli –buzzing by a disturbed beehive …

The Development Of Skeletal Muscle In Young Horses: An Ultrasonography And Satellite Cell Approach, Emma K. Lavigne

Honors Scholar Theses

Muscle growth in young horses is characterized by an increase in muscle cross-sectional area, which can be accomplished through the activation and differentiation of satellite cells. Satellite cells can be stimulated or inhibited in response to different cytokines and growth factors and are key mediators of muscle hypertrophy and regeneration. The aim of this study was to investigate the growth of the longissimus dorsi (LD) muscle in horses under 5 years of age and to obtain preliminary data on satellite cell behavior in foals. The area, width, height, and subcutaneous fat were measured using ultrasonography at 6-month increments over the …

Effects Of Pre-Release Physical Stressors On Post-Release Success Of Hatchery-Reared Spotted Seatrout, Taylor Westbrook Guest

Master's Theses

Alteration of habitat associated with coastal development and increased demand for food and recreation can result in the depletion of fisheries resources such as the Spotted Seatrout (Cynoscion nebulosus), the Gulf of Mexico’s most popular recreational fish. Stock enhancement, or the release of cultured fish to supplement wild populations, is one potential tool for managing important fisheries resources. Although much effort has gone into marine stock enhancement, the effectiveness of stocking is not well established, and techniques for ensuring success have not been developed. Although the basic biology of the Spotted Seatrout is well known, comparatively little is known about …

A Systematic Review Of The Soricimorph Eulipotyphla (Soricidae: Mammalia) From The Gray Fossil Site (Hemphillian), Tennessee, Joshua Doby

Electronic Theses and Dissertations

Due in part to the incompleteness of the Cenozoic fossil record in the eastern U.S., the evolution and immigration of shrews (Soricidae) is not well understood. A rich soricid fauna from the Gray Fossil Site (GFS), Washington County, TN, has enabled many new inferences to be made. There are 7 new species in 6 genera: Paenelimnoecus, “Blarinella”, Petenyia, Tregosorex, Crusafontina, and Gen et sp. nov. GFS species of the genera Paenelimnoecus, “Blarinella”, and Petenyia are the first occurrence of each genus in the New World. Tregosorex, Crusafontina, and the N.A. taxon Limnoecus all have their latest documented occurrence at the …

Comparison Of Microwear On Rodent Molars From Differing Species And A Wide Range Of Environments, Mikko Joiner

Anthropology Undergraduate Honors Theses

Dental microwear analysis is a very useful tool when trying to infer the diet of a particular organism. By studying the use-wear scars left on the enamel of the tooth due to eaten objects, one can infer the diet of the organism because certain types of food leave certain types of scars. For example, the consumption of tree parts produces pits, while the consumption of grasses produces striated scratches (Ungar et al., 2007). Thus, based on the type of microwear, the diet of the organism in question can be deduced, which indicates the type of environment that it lives in. …

Investigations Into The Incidence And Control Of Selected Parasites And Pathogens Which Infect Arkansas Horses, Stephanie Ann O'Berg Rainbolt

Graduate Theses and Dissertations

Parasite control is an important aspect of health management of horses, particularly the control of gastrointestinal (GI) parasites. Recently, treatment recommendations have involved selective use of anthelmintics in horses with fecal egg counts (FEC) greater than a specified threshold. The objectives of this study were; (1) to determine the prevalence of helminths in our area by egg and L3 determinations, (2) to determine if certain horses maintained low FEC, therefore eliminating the need to treat them on a year-round basis and (3) to determine the effectiveness of four common treatments (moxidectin, ivermectin (pioneer and generic), fenbendazole and pyrantel tartrate) via …

Two New Euscorpius Species From Central-Western Greece (Scorpiones: Euscorpiidae), Gioele Tropea, Victor Fet

Euscorpius

Two new Euscorpius species are described, based on specimens collected by P.M. Giachino & D. Vailati in central-western Greece in neighboring Aitoloakarnania (Western Greece) and Fokida (Central Greece) regional units. No Euscorpius specimens were previously available from this area. The first new species, Euscorpius giachinoi sp. n., is very similar to a recently described E. birulai Fet et al., 2014 from Euboea Island, and is also characterized by a low trichobothrial count (Pv = 7, et = 5), a low pectinal teeth count (Dp = 7 in males, 6 in females), and long-limbed features. The second species, …

Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell

Undergraduate Distinction Papers

Same sex pair bonding can be found throughout various animal species. These relationships can be common in monogamous species, especially when there is a lack of members of the opposite sex. Budgerigars, Melopsittacus undulatus, are a socially monogamous species, which create strong pair bonds but are also known to engage in extra pair copulations. When looking at an all-male flock of budgerigars, the question arises, are these bonds easily broken or disrupted by a third party individual. After determining seven pair bonds in a flock of 32 males, these pairs were removed from an aviary and placed in separate …

Isotopic Incorporation Rates And Discrimination Factors In Mantis Shrimp Crustaceans., Maya Devries, Carlos Del Rio, Tate Tunstall, Todd Dawson

Faculty Publications, Biological Sciences

Stable isotope analysis has provided insights into the trophic ecology of a wide diversity of animals. Knowledge about isotopic incorporation rates and isotopic discrimination between the consumer and its diet for different tissue types is essential for interpreting stable isotope data, but these parameters remain understudied in many animal taxa and particularly in aquatic invertebrates. We performed a 292-day diet shift experiment on 92 individuals of the predatory mantis shrimp, Neogonodactylus bredini, to quantify carbon and nitrogen incorporation rates and isotope discrimination factors in muscle and hemolymph tissues. Average isotopic discrimination factors between mantis shrimp muscle and the new diet …
