Lateral Dispersal Of Adult Trichoptera: Flight Distance And Traveling Pattern, Peilin Tan

All Theses

Trichoptera species (caddisfly) are usually used as bio-indictors for surface water quality due to their sensitivity to environmental changes, and if assessing water quality with light-trapped adults, knowing their travelling patterns will improve the accuracy of such assessments. To investigate how far a caddisfly will migrate from their emerging stream, three streams in South Carolina with different widths (Wildcat Creek 1.2 m, Brasstown Creek 11.2 m and Chattooga River 26.95 m) were selected for this study with light traps placed at three distances (0 m, 50 m, 100 m) from the streams. How long and when? Both species richness and …

Avian Temporal Trends And Habitat Relations Within The South Atlantic Coastal Zone, Jordan Mccall

All Theses

Despite the significance of the Hobcaw Barony in a region historically known as a waterfowl hunting paradise, the long history of the Belle W. Baruch Institute of Coastal Ecology and Forest Science on Hobcaw Barony and the establishment of the James C. Kennedy Waterfowl and Wetlands Conservation Center at the Baruch Institute in 2014, no comprehensive study of waterbirds has occurred on site. Thus, basic information, such as the number of species present, relative abundance, migration chronology, and habitat use and selection, is lacking. This research aims to form a baseline of waterbird and wetland data on the Hobcaw Barony …

Environmental Light Controls The Daily Organization Of Breathing By Activating Brn3b-Expressing Intrinsically Photosensitive Retinal Ganglion Cells In Mice, Aaron A. Jones, Allison R. Spears, Deanna M. Arble

Biological Sciences Faculty Research and Publications

Rhythmic, daily fluctuations in minute ventilation are controlled by the endogenous circadian clock located in the suprachiasmatic nucleus (SCN). While light serves as a potent synchronizer for the SCN, it also influences physiology and behavior by activating Brn3b-expressing, intrinsically photosensitive retinal ganglion cells (ipRGCs). It is currently unclear the extent to which the external light environment shapes daily ventilatory patterns independent of the SCN. To determine the relative influence of environmental light versus circadian timing on the organization of daily rhythms in minute ventilation, we used whole-body plethysmography to measure the breathing of mice housed on a non-entraining T28 cycle …

The experiment was conducted under field conditions during three maize crop succession cycles. The treatments consisted of cultivating maize during the summer, after sorghum and lablab cropped as green manure and fallow during the winter. Higher maize yields were achieved by sorghum–maize succession compared to monocropping, due to higher N fertilizer and biomass inputs …

Survival Of The Smartest? The Evolutionary Ecology Of Cognition In Anolis Lizards, Mahaut V. Sorlin

LSU New Orleans Theses and Dissertations

Cognitive processes such as learning, memory, and decision-making are integral to an organism’s fitness, allowing to integrate cues from its environment and adjust its behavior accordingly. Historically, cognitive abilities were thought to have evolved according to a Scala Naturae design—an idea that has since been disproven—which suggested that complex cognitive abilities were exclusive to “higher” taxa. This perspective has created significant phylogenetic gaps in our understanding of cognitive evolution. In this dissertation I aimed to address this issue by investigating the evolution of cognition in reptiles, focusing on the green (Anolis carolinensis) and the brown anole (Anolis …

Framing Indian Federalism, Madhav Khosla

Faculty Scholarship

This article focuses on a set of historical and contemporary developments in Indian constitutionalism that implicate the question of democracy and the question of federalism. Its goal is to connect the design and application of federal powers with what many regard as an important telos of federalism, namely, the promotion of democracy. Towards this end, it holds up for consideration India’s federal model, which, it is suggested, focuses on the presence of a subnational demos rather than the political identity of subnational units. Such an understanding of federalism de-emphasizes the territorial aspect of federalism and allows federal design to accommodate …

The Bacterial Cell Wall Components Lipopolysaccharide And Peptidoglycan Initiate Divergent Local Tissue And Systemic Inflammatory Response Profiles In The Chicken Model, Kristen A. Byrne, Gisela F. Erf

Poultry Science Faculty Publications and Presentations

The innate immune system plays an important role in the early defense against pathogens. To better understand the chicken’s innate inflammatory responses, we concurrently examined the cellular responses at the injection site and in the blood following intradermal (i.d.) injections of lipopolysaccharide (LPS) or peptidoglycan (PGN) into the pulp of growing feathers (GFs). Both LPS from Gram-negative bacteria and PGN from Gram-positive bacteria are potent stimulators of innate inflammatory responses. The time-course study conducted revealed similarly elevated levels of heterophils and macrophages in injected GF-pulps during the first 24 h for both LPS and PGN. However, PGN also stimulated rapid …

Influence Of Hydrologic And Anthropogenic Disturbance On Stream Populations And Communities, Sarah Frances Sorensen

Graduate Theses and Dissertations

Disturbances occur when an external force modifies a habitat, destroying living space, removing food resources, or altering or destroying habitat structure. In lotic systems, a primary source of disturbance is hydrologic disturbance, including drought and flood. Hydrologic disturbances lead to increased mortality rates and dispersal out of disturbed habitats, causing population sizes to decrease and changes to community structures. More research is needed on how disturbances impact stream species and communities, as disturbances are predicted to become more intense with climate change. This dissertation aims to understand how disturbance influences streams at both the population and community level, through a …

Frogs On A Plain: Spatial Ecology Of Crawfish Frogs In Arkansas’ Remnant Prairies, Elliot T. Lassiter

Graduate Theses and Dissertations

The prairie peninsula was an expansive and important habitat that covered much of midwestern North America, from Canada to Arkansas, USA. But the prairie peninsula has shrunk by as much as 99% since 1830, and therefore, land acquisition and public/private partnerships are critical for the preservation of prairies and their associated species. In Arkansas, one species that benefits from protected prairies is the Crawfish Frog (Lithobates areolatus), which is currently declining precipitously throughout its range. Adult Crawfish Frogs spend most of their lives in terrestrial refugia (crayfish burrows), making them highly vulnerable to habitat loss and fragmentation, thereby …

Exploring The Interplay Between Testosterone Levels And Gender Role Attitudes, Arial Bloshinsky

Graduate Theses and Dissertations

Traditional gender role attitudes align men with resource management and women with nurturing. The Challenge Hypothesis proposes that resource management is associated with higher testosterone levels, whereas nurturing is associated with lower testosterone levels. Therefore, traditional gender role attitudes may be associated with people’s testosterone levels. Furthermore, during the transition to parenthood, traditional gender role attitudes may become particularly salient, as shifting biological, social, and cultural roles during this transition make these attitudes an integral part of daily life. In this longitudinal study of expectant couples, participants completed a baseline survey and baseline session, during which they completed measures and …
