The Fox In The Henhouse: Responses Of Chickens (Gallus Domesticus) To The Scent Of A Predator, Andrew C. Alba, Gregory B. Cunningham

Biology Faculty/Staff Publications

Domestic chickens (Gallus domesticus) are often used as a model species in testing bird olfaction. Previous studies have indicated that domestic chicks can discriminate between various odors, are attracted to familiar odors, and use olfactory cues during food selection. Additionally, studies have indicated that olfaction plays an important role in predator recognition in a variety of songbirds. It has yet to be demonstrated, however, whether chickens can detect predators using olfactory cues. To address this, we tested 1-2 day old naïve chicks with undiluted fox urine and found that they were able to detect this scent. This could …

The phytochemical screening revealed the presence of phlobatannins, carbohydrates, tannins, glycosides, volatile oils, resins, balsams, flavonoids and saponins, while terpenes, sterols, anthorquinones and phenols were absent. The pharmacognostic analysis revealed moisture content of 11.60 %, ash value of 6.24%, water soluble extractive value of 22.45 %, alcohol soluble extractive value of 5.99% and acid insoluble ash of 1.21%. The thin layer chromatography development revealed three spots for hexane extract, six spots for ethyl acetate and five spots for methanol.

Respecting Working Mothers With Infant Children: The Need For Increased Federal Intervention To Develop, Protect, And Support A Breastfeeding Culture In The United States, Heather M. Kolinsky

Faculty Scholarship

The author argues that the benefits of breastfeeding are overwhelming and that more needs to be done to ensure that all women have a viable option to continue breastfeeding upon returning to work, particularly the working poor and minorities. Those least likely to breastfeed are more likely to be part of an at risk population in terms of health. Most significantly, the lack of a cohesive policy in the workplace has had a disparate impact on the most vulnerable populations of breastfeeding mothers and their children. The lack of federal protection and a patchwork of protection in the states have …

Ecological And Evolutionary Interactions Between The Copepod Acartia Tonsa And The Dinoflagellate Cochlodinium Polykrikoides, Xiaodong Jiang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The dinoflagellate Cochlodinium polykrikoides Margalef has formed dense blooms and caused severe fish kills on a global scale in recent decades. The effects of C. polykrikoides on survival, feeding, and fecundity of the copepod Acartia tonsa Dana were examined to determine if it is harmful to grazers. C. polykrikoides significantly reduced copepod survival, feeding, and fecundity within the range of bloom densities. Two bioassay experiments suggested that copepod mortality was due to multiple harmful compounds produced by C. polykrikoides. Although Cochlodinium polykrikoides is harmful to Acartia tonsa at high cell densities, the mixed-diet experiments indicated that C. polykrikoides was nutritious …

Dopamine And Leptin Interactions In Rodent Models Of Obesity And Cocaine Abuse, Michael Michaelides

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Dopamine (DA) is a catecholamine neurotransmitter and along with its receptors plays a well-documented role in motivation and goal-directed behavior. Clinical studies have previously documented striatal DA D2 receptor (D2R) deficits in obese individuals and chronic cocaine users. These studies suggest that impaired DA-D2R signaling in the striatum may underlie deficits in goal-directed behaviors that can ultimately lead to obesity and drug addiction. However, such studies have not addressed the question of whether D2R deficits precede obesity and cocaine abuse or whether D2R decline in response to repeated overeating and cocaine use.This thesis aims to answer this question by further …

Restoration Of The Hudson River Oyster: A Physiological And Spatial Assessment Of Crassostrea Virginica's Restoration Potential In The Hudson River, Ny, Adam Faulkner Starke

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The Hudson River was once home to abundant eastern oyster (Crassostrea virginica, (Gremlin 1791) populations which catered to an enormous fishery and supplied a number of vital ecological services to the estuary. Since this time, oysters have become depleted and the estuary's vitality has been compromised. Recognizing the current state of the Hudson, a comprehensive restoration plan has been implemented and targets the recovery of oysters and oyster reefs. To begin moving forward with these plans, a two year study investigating the physiological responses of the oyster to New York's Hudson River was made. The results have provided useful insights …

Examining The Dissemination Of Innovations In The Sporting Goods Industry., Marion E. Hambrick

Electronic Theses and Dissertations

US consumers spend $87 million annually on sporting goods and services (National Sporting Goods Association, 2008). Each year sporting goods manufacturers also spend millions of dollars creating innovative products for consumers looking to improve their playing performances and enjoyment of the sport (Reisinger, 2002). Manufacturers want to receive adequate returns on their research and development investments and create innovations consumers support and want to buy (Berman & McLaughlin, 1973). To facilitate the dissemination of innovations, manufacturers provide information about their innovations to increase product awareness and help consumers make informed purchasing decisions (Rogers, 2003). The purpose of the current study …

Abundance Of Arbuscular Mycorrhizae In Epiphytic Orchidaceae: Abiotic, Biotic And Taxonomic Factors, May 2010, Logan E. Smestad

Monteverde Institute: Tropical Ecology and Conservation

Despite nutrient stress, not all epiphytes have mycorrhizal associations, including some epiphytic orchids (Lesica & Antibus 1990). In this study epiphytic orchids were collected from tree and limb falls in the Monteverde Cloud Forest, Costa Rica. Abiotic factors such as branch circumference, presence or absence of moss mats, thickness of moss mats, substrate pH and moisture content were measured for their impact on mycorrhizal abundance. Biotic factors such as relative age of the orchid, plant height and the presence or absence of pseudobulbs were also considered. Finally, taxonomic factors were assessed as abundance of mycorrhizae related to the Pleurothallid or …

The Effects Of Aerobic Exercise On Embryonic And Fetal Development In The Pregnant Mare, Jason Anton

All Theses

Horses are natural athletes and are commonly competed during early pregnancy. Because horses have singleton pregnancies and are conditioned to human interaction, they may prove to be a useful model in lending greater understanding of the numerous etiologies of intra-uterine growth restriction that is found in women and other mammals. Currently, there has been little research conducted to determine the effects that stress, in the form of aerobic exercise, has on early embryonic and fetal development in the horse. More research is needed to further understand the effects that stress has on early conceptus development in the mare.
The research …

Power Play In The African-American Home: Female Authority And Male Neglect In The Private Spheres Of Ernest Gaines's A Lesson Before Dying, Of Love And Dust, And In My Father's House, Lauren Joy Roth

Masters Theses

Ernest J. Gaines's spaces serve as sites for power negotiation, in particular within his ethnic community. Drawing from the memories of his life in the South, Gaines writes layers of significance into the spaces of the fictitious towns he creates in his novels. Rather than reducing the environment to mere background material, Gaines's private and public spaces both communicate to and inform his audience of power struggles. In his novels, A Lesson Before Dying, Of Love and Dust, and In My Father's House, the locales, the very spaces themselves, inform. The boundary markers of the private and public world both …

Siamese Cooperates With The Cdh1-Like Protein Ccs52a1 To Establish Endoreplication In Arabidopsis Thaliana Trichomes, Remmy Kasili, Jason D. Walker, L. Alice Simmons, Jing Zhou, Lieven De Veylder, John C. Larkin

Faculty Publications

Endoreplication, also known as endoreduplication, is a phyogenetically widespread modified version of the cell cycle in which DNA replication is not followed by cell division. The SIAMESE (SIM) gene of Arabidopsis thaliana encodes the founding member of a novel class of plant-specific cyclin-dependent kinase (CDK) inhibitors and is a key regulator of endoreplication during the development of trichomes (shoot epidermal hairs). Here, we have identified mutations in the CCS52A1 gene as genetic modifiers of the multicellular trichome phenotype of sim mutants. Loss-of-function ccs52A1 mutations dramatically enhance the multicellularity of sim mutants trichomes in double mutants, whereas overexpression of CCS52A1 completely …
