Music Advocacy: The Cognitive Development, Behavioral And Emotional Management, And Academic Success That Music Education Provides Students In Louisiana’S Low Socioeconomic Elementary Schools, Cory D. Dugar

Doctoral Dissertations and Projects

There are many technological curricular activities in math and science classrooms, yet few are found in music classrooms. Although many elementary schools may be benefiting from advocacy for music and technology, many elementary schools in the state of Louisiana have lost funding for music programs. For the Louisiana Department of Education to act as an advocate for music education, there must be a thorough understanding of the benefits of music education. Extensive research is one way to suggest that elementary music classes can raise the cognitive capacity of elementary students and could be the catalyst for ensuring the upcoming generation’s …

Documentation Of Atlantic Tarpon (Megalops Atlanticus) Space Use And Move Persistence In The Northern Gulf Of Mexico Facilitated By Angler Advocates, J. Marcus Drymon, Matthew B. Jargowsky, Michael A. Dance, Mitchell Lovell, Crystal L. Hightower, Amanda E. Jefferson, Andrea M. Kroetz, Sean P. Powers

University Faculty and Staff Publications

Atlantic tarpon (Megalops atlanticus, hereafter tarpon) are facing a multitude of stressors and are considered Vulnerable by the IUCN; however, significant gaps remain in our understanding of tarpon space use and movement. From 2018 to 2019, citizen scientists facilitated tagging of 23 tarpon with SPOT tags to examine space use and movement across the northern Gulf of Mexico. Movement-based kernel densities were used to estimate simplified biased random bridge-based utilization distributions and a joint move persistence model was used to estimate a behavioral index for each fish. Tarpon showed consistent east–west movement from the Alabama/Florida border to Louisiana, and utilization …

Apparent Resilience To Fire Of Native Bee (Hymenoptera: Apoidea) Communities From Upland Longleaf Pine Forests In Louisiana And Mississippi, Sara A. Simmons, Janice L. Bossart

Biological Sciences Faculty Publications

Controlled burning is an essential tool for restoration and management of Pinus palustris (Longleaf Pine) habitats, yet effects of controlled burning on insect species, including pollinators, are rarely considered in conservation planning. We used blue vane traps to sample native bees (Hymenoptera: Apoidea) at recently burned and unburned sites in 2 Longleaf Pine upland forests in Mississippi and Louisiana. Our objective was to quantify short-term effects of controlled burns given fire-return intervals of 1-2 years are now regularly employed to manage Longleaf Pine woodlands. We sampled during 2016 and 2017 and collected 1777 native bees, representing 43 species. Recent fire …

Protocol And Results From The First Season Of Captive-Rearing Whooping Cranes For A Non-Migratory Release In Louisiana, Glenn H. Olsen, Jane N. Chandler

Proceedings of the North American Crane Workshop

The principal historic range of the whooping crane (Grus americana) consisted of the tall grass prairies and wetlands of southwest Louisiana, Texas, and parts of Mexico (Allen 1952). Whooping cranes migrated there from Illinois, Iowa, Minnesota, Dakotas, Manitoba, Saskatchewan, Alberta, and breeding grounds of the remnant flock in and near Wood Buffalo National Park, Canada.

Winter Movements Of Louisiana Pine Snakes (Pituophis Ruthveni) In Texas And Louisiana, Josh B. Pierce, D. Craig Rudolph, Shirley J. Burgdorf, Richard R. Schaefer, Richard N. Conner, John G. Himes, C. Mike Duran, Laurence M. Hardy, Robert R. Fleet

Faculty Publications

Despite concerns that the Louisiana Pine Snake (Pituophis ruthveni) has been extirpated from large portions of its historic range, only a limited number of studies on their movement patterns have been published. Winter movement patterns are of particular interest since it has been hypothesized that impacts of management practices would be reduced during the winter. Using radiotelemetry, we determined winter movement patterns of Louisiana Pine Snakes (11 males, 8 females) in 5 study areas (2 in Louisiana and 3 in Texas). Movements during winter (November–February) were greatly curtailed compared to the remainder of the year; however, snakes occasionally undertook substantial …

Home Ranges And Habitat Use Of Brown Pelicans (Pelecanus Occidentalis) In The Northern Gulf Of Mexico, D. Tommy King, Buddy L. Goatchter, Justin W. Fischer, John Stanton, James M. Lacour, Scott C. Lemmons, Guiming Wang

USDA Wildlife Services: Staff Publications

Little is known about movements and habitat use of Brown Pelicans (Pelecanus occidentalis) in the northern Gulf of Mexico. We attached satellite transmitters to 18 adult Brown Pelicans (nine males, nine females) that were captured on Grand Isle along the Louisiana coast during 31 August-2 September 2010. Their movements and habitat use were tracked between September 2010 and March 2012. Nine of the Brown Pelicans remained proximate to the Louisiana coast; four ranged along the coasts of Alabama, Mississippi, and Louisiana; three moved from Louisiana to Texas; and two migrated across the Gulf of Mexico to the Yucatan Peninsula. …

Behavioural Display Systems Across Nine Anolis Lizard Species: Sexual Dimorphisms In Structure And Function, Michele A. Johnson, J. Wade

Biology Faculty Research

Relationships between structure and function are a primary focus in biology, yet they are most often considered within individual species. Sexually dimorphic communication behaviours and the morphology of associated structures can vary widely, even among closely related species, and these traits provide an ideal opportunity to investigate the evolution of structure-function patterns. Using nine Anolis lizard species, we addressed a series of questions regarding sex differences in and the evolution of relationships between extension of the throat fan (dewlap) and morphology of the muscles and cartilage controlling it. The main results indicated that within species, males displayed the dewlap more …

The Importance Of Pulsed Physical Events For Sustainability Of Louisiana Coastal Forested Wetlands, William Conner, J W. Day Jr, G P. Shaffer

Publications

A number of freshwater diversions from the Mississippi River into Louisiana’s coastal wetlands are currently in operation or in the planning stage. These diversions have multiple objectives including maintaining a desirable salinity gradient, restoring deteriorating wetlands, and enhancing fisheries. The extensive freshwater forested wetlands surrounding the western end of Lake Pontchartrain receive little or no sediment input and are currently deteriorating due to continuous flooding. Diverting nutrient-rich water through wetlands can lead to substantial nutrient removal and to enhanced accretion. The objective of this paper is to compare the impacts on freshwater wetland ecology, accretion, and water quality of several …

Historical Notes On Whooping Cranes At White Lake, Louisiana: The John J. Lynch Interviews, 1947-1948, Gay M. Gomez, Roderick C. Drewien, Mary Lynch Courville

Proceedings of the North American Crane Workshop

In May 1939 biologist John J. Lynch of the U.S. Bureau of Biological Survey conducted an aerial survey that documented the existence of a non-migratory population of whooping cranes (Grus americana) near White Lake in southwest Louisiana. Lynch found 13 cranes, including 2 pre-fledged young, confirming breeding. Lynch’s survey occurred, in part, because fur trappers and alligator hunters working in the White Lake marshes had informed the biologist of the cranes’ presence and habits. Lynch continued his contacts with these knowledgeable marsh users, and in 1947 and 1948 interviewed at least 7 individuals. In 2001, M. L. Courville, …

Project Report No. 65, Stumpage Price Trends Of Sawtimber And Pulpwood In East Texas And Louisiana, Dean W. Coble, Shiaolin Cheng

Informal Project Reports

A fifteen-year stumpage price update and analysis for pine and hardwood in East Texas are reported. Thepricesofsawtimberandpulpwoodare presented for both pine and hardwood plantations by using 1988 to 2003 stumpage prices from the Texas Forest Service and Louisiana Department of Agriculture. Timber prices increased steadily from 1988 to the late 1990's, peaked, then declined into 2003 for both Louisiana and Texas. Louisiana prices, though, have remained higher than those for Texas.

Microalgal-Meiofaunal Trophic Relationships In Muddy Intertidal Estuarine Sediments, James L. Pinckney, Kevin R. Carman, S. Elizabeth Lumsden, Sabrina N. Hymel

Faculty Publications

The determination of the primary factors controlling carbon (C) transfer rates in situ are a basic requirement for developing a mechanistic view of the processes that regulate benthic microbial community structure and function. In many estuarine ecosystems, the base of the food web is dominated by microalgal production; however, information on the quantitative relationships and process rates of meiofaunal grazers and benthic microalgal (BMA) producers is limited to a few habitats and short temporal scales. The primary objective of this study was to examine the trophic interactions between meiofaunal grazers and BMA producers to determine if grazing is a primary …

Whooping Cranes Breeding At White Lake, Louisiana, 1939: Observations By John J. Lynch, U. S. Bureau Of Biological Survey, Roderick C. Drewien, John Tautin, Mary Lynch Courville, Gay M. Gomez

Proceedings of the North American Crane Workshop

On 15 May 1939, Jo1m J. Lynch of the U.S. Bureau of Biological Survey located l3 whooping cranes (Grus americana), including 2 prefledged young, during an aerial survey near White Lake in southwestern Louisiana. His observation was the last historic record of whooping cranes breeding in the wild in the United States, and it confinned the presence of a nonmigratory breeding population along the Gulf Coast. While reviewing old U.S. Fish and Wildlife Service files at the National Archives in 1999, we located Lynch's original 1939 field note, 2 letters, 5 photographs, and a draft manuscript describing the …

Nitrogen Budgets Of Phloem-Feeding Bark Beetles With And Without Symbiotic Fungi, Matthew P. Ayres, Richard T. Wilkens, Jonathan J. Ruel, María J. Lombardero, Erich Vallery

Dartmouth Scholarship

The nitrogen content of plant tissue is low relative to that of herbivores; as a consequence, dietary N can limit the growth and reproduction of herbivores and select for attributes that increase N acquisition. Bark beetles face a particularly severe challenge because the phloem that they consume is very low in nitrogen and phosphorus relative to their requirements. We quantified variation in the phloem concentrations of N and P in the host tree, Pinus taeda, and evaluated the following hypotheses regarding the role of symbiotic fungi in nutrient budgets of the herbivore Dendroctonus frontalis: D. frontalis experience variation …

Whooping Cranes In Southwest Louisiana: History And Human Attitudes, Gay M. Gomez

Proceedings of the North American Crane Workshop

When whooping cranes (Grus americana) inhabited southwest Louisiana's coastal marshes, residents viewed them as a food source and a crop pest, and shooting was commonplace. Local attitudes have changed as a result of education, stricter law enforcement, and decreased dependence on wildlife for subsistence, but hunting remains widespread. A 1977 proposal to reintroduce whooping cranes to southwest Louisiana generated strong opposition from the Louisiana Wild Life and Fisheries Commission (now Louisiana Department of Wildlife and Fisheries), based on concerns about critical habitat and its likely impact on waterfowl hunting and other traditional marsh uses. These concerns remain, though …
