Protein Kinase M Zeta-Mediated Ltp Maintenance In The Non-Human Primate Hippocampus: A Role For Stress And Serotonergic Signaling In Affective Processing, Sasha L. Fulton
Protein Kinase M Zeta-Mediated Ltp Maintenance In The Non-Human Primate Hippocampus: A Role For Stress And Serotonergic Signaling In Affective Processing, Sasha L. Fulton
Theses and Dissertations
Early-Life Stress (ELS) is associated with vulnerability to mood disorder, but it’s not well understood how ELS contributes to deficits in cognitive function. Atypical PKMzeta is critical for LTP maintenance and memory. The current study aims to characterize the ELS phenotype with respect to this key marker of hippocampal LTP.
Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph
Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph
Theses and Dissertations
(+)-Boldine, an aporphine alkaloid, is reported to be biologically active at various Central Nervous System(CNS) receptors. However, only a few Structure Activity Relationship(SAR) studies have been conducted using boldine’s aporphine scaffold. A library of novel analogs was synthesized from boldine to understand the effect of bisbenzylation at C2 and C9 positions on the affinity and selectivity at the serotonin receptors.
Investigating The Nest Sanitation Hypothesis In A Rejecter Species: Is Sanitation A Proximate Link, Pre-Adaptation, Or By-Product Of Egg Ejection?, Alec B. Luro
Theses and Dissertations
Nest sanitation, a behavior similar in motor pattern to egg ejection, has been proposed repeatedly as a potential pre-adaptation to foreign egg ejection in avian brood parasites hosts. We found no support for the sanitation hypothesis--therefore we suggest egg ejection may have evolved independently of sanitation.
Metabolic Limits And Adaptation In Humans: Daily Energy Expenditure In Race Across The Usa Athletes, Caitlin Thurber
Metabolic Limits And Adaptation In Humans: Daily Energy Expenditure In Race Across The Usa Athletes, Caitlin Thurber
Theses and Dissertations
A longitudinal doubly labeled water study of total energy expenditure (TEE) in Race Across the USA athletes, examining the effects of extremely high levels of activity on metabolic adaptation.
Ménage À Trois In The Atlantic Brief Squid (Lolliguncula Brevis): Prior Presence Affects Mate Choice, Rachel A. Schlessinger
Ménage À Trois In The Atlantic Brief Squid (Lolliguncula Brevis): Prior Presence Affects Mate Choice, Rachel A. Schlessinger
Theses and Dissertations
Lolliguncula brevis given prior presence experienced a significantly greater number of contacts with opposite sex squid than rivals. Males given prior presence also spent significantly more time in proximity to females than rivals. This suggests that for both female and male Atlantic brief squid, having prior presence influences mating behavior.
Total Energy Expenditure In Captive Sapajus Apella, Wren Edwards
Total Energy Expenditure In Captive Sapajus Apella, Wren Edwards
Theses and Dissertations
Primates expend approximately 50% less energy (kcal/day) for their body size than other eutherians. Using the doubly labeled water method, I investigated total energy expenditure (TEE) and physical activity in Sapajus apella. S. apella TEE was similar (p=0.67) to other platyrrhines, but 54% lower than expected for body mass.
Exploring Data Mining Techniques For Tree Species Classification Using Co-Registered Lidar And Hyperspectral Data, Julia K. Marrs
Exploring Data Mining Techniques For Tree Species Classification Using Co-Registered Lidar And Hyperspectral Data, Julia K. Marrs
Theses and Dissertations
NASA Goddard’s LiDAR, Hyperspectral, and Thermal imager provides co-registered remote sensing data on experimental forests. Data mining methods were used to achieve a final tree species classification accuracy of 68% using a combined LiDAR and hyperspectral dataset, and show promise for addressing deforestation and carbon sequestration on a species-specific level.
A Case Study: Observations Of Behaviors & Vocalizations In A Captive Asian Elephant (Elephas Maximus) During Quarantine, Alexandra L. Dilley
A Case Study: Observations Of Behaviors & Vocalizations In A Captive Asian Elephant (Elephas Maximus) During Quarantine, Alexandra L. Dilley
Theses and Dissertations
Bozie, an Asian elephant (Elephas maximus), was relocated from the Baton Rouge Zoo to Smithsonian’s National Zoo. During a requisite 29-day quarantine period, I recorded Bozie’s stress-related behaviors and the vocalizations she produced when she was alone and with her keepers in free and protected contact.
Function Of Male Sexual Signaling In The Brief Squid (Lolliguncula Brevis), Lauren A. Piperno
Function Of Male Sexual Signaling In The Brief Squid (Lolliguncula Brevis), Lauren A. Piperno
Theses and Dissertations
This study explores male signaling in the brief squid. Females spend more time close to males during male signal production, but did not change their orientation to enable mating. Females reduced their own signaling during male signals. Male sexual signaling is directed at females, yet the precise function remains elusive.
