Cambial Phenology Informs Tree-Ring Analysis Of Fire Seasonality In Coastal Plain Pine Savannas, Monica T. Rother, Jean M. Huffman, Grant L. Harley, William J. Platt, Neil Jones, Kevin M. Robertson, Steve L. Orzell Feb 2018

Cambial Phenology Informs Tree-Ring Analysis Of Fire Seasonality In Coastal Plain Pine Savannas, Monica T. Rother, Jean M. Huffman, Grant L. Harley, William J. Platt, Neil Jones, Kevin M. Robertson, Steve L. Orzell

Faculty Publications

© 2018, The Author(s). Understanding of historical fire seasonality should facilitate development of concepts regarding fire as an ecological and evolutionary process. In tree-ring based fire-history studies, the seasonality of fire scars can be classified based on the position of the fire scar within or between growth rings. Cambial phenology studies are needed to precisely relate a fire-scar position to months within a year because the timing of dormancy, earlywood production, and latewood production varies by species and location. We examined cambial phenology patterns of longleaf pine (Pinus palustris Mill.), slash pine (P. elliottii Engelm.), and South Florida slash pine …

Crop insurance is a viable solution to reduce the vulnerability of smallholder farmers to risks from pest and disease outbreaks, extreme weather events, and market shocks that threaten their household food and income security. In developing and emerging countries, the implementation of area yield-based insurance, the form of crop insurance preferred by clients and industry, is constrained by the limited availability of detailed historical yield records. Remote-sensing technology can help to fill this gap by providing an unbiased and replicable source of the needed data. This study is dedicated to demonstrating and validating the methodology of remote sensing and crop …

Trade-Offs And Synergies Of Ecosystem Services In The Taihu Lake Basin Of China, Xuning Qiao, Yangyang Gu, Changxin Zou, Lei Wang, Juhua Luo, Xianfeng Huang

Faculty Publications

Understanding the spatial interactions among multiple ecosystem services is crucial for ecosystem services management. Ecosystem services, including crop production, freshwater supply, aquatic production, net primary production, soil conservation, water conservation, flood regulation, forest recreation, were measured at 1-km grid scale covering the Taihu Lake Basin (TLB) of China. Our objective is to get a comprehensive understanding of the spatial distributions, trade-offs, synergies of multiple ecosystem services across the TLB. Our results found that: 1) majority of ecosystem services were clustered in space and had a similar spatial distribution pattern with the geographical resource endowment. Most of the landscape contributed a …

Investigation Of Morphological Changes In Small Coastal Rivers During Flood, Tanzina Afrin Jan 2018

Investigation Of Morphological Changes In Small Coastal Rivers During Flood, Tanzina Afrin

LSU Master's Theses

The delivery of fluvial sediment to coastal margins is one of the major concerns for river and coastal morphodynamics. Relevant research has primarily focused on large rivers that transport substantial sediment load and thus are responsible for building deltaic landscapes. However, less research is concentrated on small coastal rivers. A need exists to better understand the sediment dynamics in small coastal rivers that have different backwater regimes than their larger counterparts. The main objective of this research was to examine the influence of backwater on the morphodynamics of a small coastal meandering river during a large flood event. The investigation …

Identifying Genome-Wide Immune Gene Variation Underlying Infectious Disease In Wildlife Populations - A Next Generation Sequencing Approach In The Gopher Tortoise, Jean P. Elbers, Mary B. Brown, Sabrina S. Taylor Jan 2018

Identifying Genome-Wide Immune Gene Variation Underlying Infectious Disease In Wildlife Populations - A Next Generation Sequencing Approach In The Gopher Tortoise, Jean P. Elbers, Mary B. Brown, Sabrina S. Taylor

Faculty Publications

Background: Infectious disease is the single greatest threat to taxa such as amphibians (chytrid fungus), bats (white nose syndrome), Tasmanian devils (devil facial tumor disease), and black-footed ferrets (canine distemper virus, plague). Although understanding the genetic basis to disease susceptibility is important for the long-term persistence of these groups, most research has been limited to major-histocompatibility and Toll-like receptor genes. To better understand the genetic basis of infectious disease susceptibility in a species of conservation concern, we sequenced all known/predicted immune response genes (i.e., the immunomes) in 16 Florida gopher tortoises, Gopherus polyphemus. All tortoises produced antibodies against Mycoplasma agassizii …

Evolution Of The Maximum Upper Level Divergence Field In Gulf-Atlantic Tropical Cyclogenesis, Sara A. Ates Jan 2018

Evolution Of The Maximum Upper Level Divergence Field In Gulf-Atlantic Tropical Cyclogenesis, Sara A. Ates

LSU Master's Theses

Upper-level (horizontal) divergence (ULD) is an important variable in tropical weather systems. As part of the circulation within a tropical cyclone (TC), it carries air in the upper troposphere away from the center of circulation (COC). To date, most research assumes the 200 hPa pressure level (approximately 12 km, varying with latitude and time of year) as the height for maximum ULD in a TC, possibly because weather observation at the 200 hPa level by radiosonde have remained mandatory for aviation purposes. The more recent availability of gridded, high-spatial-resolution, global “reanalysis” data at multiple levels, along with improvements in spatial …

Sea-Level Rise Tipping Point Of Delta Survival, R. Eugene Turner, M S. Kearney, R W. Parkinson Jan 2018

Sea-Level Rise Tipping Point Of Delta Survival, R. Eugene Turner, M S. Kearney, R W. Parkinson

Faculty Publications

The estimated rate of global eustatic sea-level rise (RSLR) associated with the formation of 36 of the world's coastal deltas was calculated for the last 22,000 years. These deltas are located in a variety of environmental settings with respect to tidal range, isostasy, and climate. After correcting the original uncalibrated radiocarbon age estimates to calibrated years, 90% of the deltas appear to have formed at an average age of 8109 +/- 122 before present (BP) and a median age of 7967 BP. This age corresponds to a period of significant deceleration in the RSLR to between 5 mm y(-1) and …

American Amphibious Warfare: The Roots Of Tradition To 1865, Hal Friedman Jan 2018

American Amphibious Warfare: The Roots Of Tradition To 1865, Hal Friedman

Civil War Book Review

Gary Ohl’s book on Early American amphibious warfare is a welcome addition to the historiography on this highly specialized aspect of naval warfare. He introduces new concepts or perspectives that I think will assist other scholars in their endeavors. At the same time, he also employs this history in a way that might be very valuable to strategic planners and policymakers. As such, the book is not just history but informed historical policy analysis. The latter, however, may alienate purists as much as it attracts practitioners.

Cardiovascular disparities remain pervasive in the United States. Unequal disease burden is evident among population groups based on sex, race, ethnicity, socioeconomic status, educational attainment, nativity, or geography. Despite the significant declines in cardiovascular disease mortality rates in all demographic groups during the last 50 years, large disparities remain by sex, race, ethnicity, and geography. Recent data from modeling studies, linked micromap plots, and small-Area analyses also demonstrate prominent variation in cardiovascular disease mortality rates across states and counties, with an especially high disease burden in the southeastern United States and Appalachia. Despite these continued disparities, few large-scale intervention studies …

Linking Racial Composition, Black–White Inequality, And Regional Difference: The Role Of Migration, Heather A. O’Connell Jan 2018

Linking Racial Composition, Black–White Inequality, And Regional Difference: The Role Of Migration, Heather A. O’Connell

Faculty Publications

The percent black–inequality relationship and the unique position of the South have been cornerstones of research on U.S. racial inequality. Using an innovative methodological approach, I address how migration contributes to our understanding of the percent black– inequality relationship. I find that the educationally selective migration of blacks and whites significantly contributes to the percent black–inequality relationship via compositional changes. However, any explanatory power is limited to the non-South. Migration plays a role in understanding this relationship, yet processes related to black population concentration still generate black disadvantage anew, particularly within the South.

Insects that live in the saltwater and brackish marshes, which fringe the northern coast of the Gulf of Mexico, are largely unstudied. During 2011-2013, a survey of insect fauna of the coastal salt marshes of the Mississippi Delta in Louisiana was conducted. We present the species of terrestrial representatives of Heteroptera and Auchenorrhyncha collected during that study. The Auchenorrhyncha are represented by 33 species in 6 families, with Cicadellidae (16 species) and Delphacidae (13 spp.), and are the most diverse. The terrestrial heteropterans are represented by 11 species in 5 families with the majority of species in Miridae (6 spp.). …

Quantifying Episodic Erosion And Transient Storage On The Western Margin Of The Tibetan Plateau, Upper Indus River, Tara N. Jonell, Lewis A. Owen, Andrew Carter, Jean Luc Schwenniger, Peter D. Clift

Faculty Publications

Copyright © University of Washington. Published by Cambridge University Press, 2017. Transient storage and erosion of valley fills, or sediment buffering, is a fundamental but poorly quantified process that may significantly bias fluvial sediment budgets and marine archives used for paleoclimatic and tectonic reconstructions. Prolific sediment buffering is now recognized to occur within the mountainous upper Indus River headwaters and is quantified here for the first time using optically stimulated luminescence dating, petrography, detrital zircon U-Pb geochronology, and morphometric analysis to define the timing, provenance, and volumes of prominent valley fills. This study finds that climatically modulated sediment buffering occurs …

© 2017 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. We report the first complete mitochondrial genomes of three species of eleotrid fishes from the Pacific and Atlantic watersheds of Panama: Eleotris amblyopsis, E. picta, and Hemieleotris latifasciata. The three species have similar mitochondrial genomes with identical gene order; however, there are differences in the length of control region, 16S rRNA, and in seven of the tRNAs. In addition, ATP8 is one codon shorter in E. picta than in E. amblyopsis or H. latifasciata. We infer a phylogeny for Gobiiformes based on all mitochondrial protein-coding …

We examined organic-walled dinoflagellate cysts from one 210Pb-dated sediment core and 39 surface sediment samples from the northern Gulf of Mexico to determine the relationship between nutrient enrichment and cyst assemblages in this region characterized by oxygen deficiency. The core spans from 1962 to 1997 and its sampling location is directly influenced by the Mississippi River plume. Surface sediments were collected in 2006, 2007, 2008, and 2014 and represent approximately 1 to 4 years of accumulation. A total of 57 cyst taxa were recorded, and four heterotrophic taxa in particular were found to increase in the top section (1986–1997) of …

Erosion And Accretion On A Mudflat: The Importance Of Very Shallow-Water Effects, Benwei Shi, James R. Cooper, Paula D. Pratolongo, Shu Gao, T. J. Bouma, Gaocong Li, Chunyan Li, S. L. Yang, Ya Ping Wang Dec 2017

Erosion And Accretion On A Mudflat: The Importance Of Very Shallow-Water Effects, Benwei Shi, James R. Cooper, Paula D. Pratolongo, Shu Gao, T. J. Bouma, Gaocong Li, Chunyan Li, S. L. Yang, Ya Ping Wang

Faculty Publications

Understanding erosion and accretion dynamics during an entire tidal cycle is important for assessing their impacts on the habitats of biological communities and the long-term morphological evolution of intertidal mudflats. However, previous studies often omitted erosion and accretion during very shallow-water stages (VSWS, water depths < 0.20 m). It is during these VSWS that bottom friction becomes relatively strong and thus erosion and accretion dynamics are likely to differ from those during deeper flows. In this study, we examine the contribution of very shallow-water effects to erosion and accretion of the entire tidal cycle, based on measured and modeled time-series of bed-level changes. Our field experiments revealed that the VSWS accounted for only 11% of the duration of the entire tidal cycle, but erosion and accretion during these stages accounted for 35% of the bed-level changes of the entire tidal cycle. Predicted cumulative bed-level changes agree much better with measured results when the entire tidal cycle is modeled than when only the conditions at water depths of >0.2 m (i.e., probe submerged) are considered. These findings suggest that the magnitude of bed-level changes during VSWS should not be neglected when modeling morphodynamic processes. Our results are useful in understanding the mechanisms of micro-topography formation and destruction that often occur at VSWS, and also improve our understanding and modeling ability of coastal morphological …
