Measuring sound-induced motions of the alligator lizard cochlea
… measurements of sound-induced motion of the alligator lizard cochlea. Novel methods were developed to maintain the cochlea in vitro for the time required to measure three-dimensional motions. Three-dimensional images of cochlear motion were taken by illuminating the cochlea with a …

Proteomic Analysis of the Blood of <i>Alligator mississippiensis</i>
My research focus was to investigate alligator blood using mass spectrometry-based proteomics methods to understand their innate immune systems. The first goal was to sequence peptides and proteins from the blood serum and leukocytes using tandem mass spectrometry and <i>de novo</i> sequencing. The …

Analysis of Drivers of Spring Alligator Hunting in Texas and Policy Implications
… index (PCI2) to a case study on American alligator (Alligator mississippiensis) hunters in non-core counties in Texas. We surveyed 318 spring alligator hunters who had legally taken an alligator within the last five years and asked them to evaluate and indicate the level of acceptability …

Spatial Behavior and Population Estimation of the Alligator Snapping Turtle (Macrochelys Temminckii)
<p>The alligator snapping turtle (<em>Macrochelys </em><em>temminckii</em>) is the largest freshwater turtle species in North America. Populations have been subjected to over a century of commercial and recreational harvest, causing large scale population declines. Additionally, their aquatic …

Demography of Alligator Snapping Turtles (Macrochelys Temminckii) Along a Fishing Pressure Gradient
<p>Passive fishing gear is a threat to the alligator snapping turtle (<em>Macrochelys temminckii</em>). The spatio-temporal persistence of this threat and its impacts on <em>M. temminckii</em> populations has not been quantified. I quantified the density of passive fishing gear and the demographic …

Reproductive Biology of Alligator Snapping Turtles: Behavior, Reproductive Investment, and Nest Predation
… three critical aspects of reproduction in the alligator snapping turtle (Macrochelys temminckii), a model organism that is of great conservation interest. Specifically, I studied: (1) nesting behavior and (2) maternal reproductive investment patterns in a captive alligator snapping turtle …

Reproductive Biology and Conservation Genetics of the Alligator Snapping Turtle (Macrochelys Temminckii)
<p>abstract: The alligator snapping turtle (Macrochelys temminckii) is a highly aquatic turtle only found in Gulf of Mexico drainages. The biology of this species remains relatively unknown, despite years of harvest and use as a zoological attraction. The purposes of this study were to (1) …

Detection of the bloodmeal origin of mosquitoes collected at alligator farms, and West Nile Virus activity in mosquitoes collected from alligator farms, sentinel chicken surveillance sites, and larval habitats
… mosquitoes as vectors of WNV for captive alligators, mosquitoes were collected using Centers for Disease Control (CDC) light traps, gravid traps, backpack aspirators and resting boxes at three commercial Louisiana alligator farms from 2004 to 2006. The bloodmeal origins of 237 …

Aquatic Turtle Community Dynamics in Relation to Reintroduction of Alligator Snapping Turtles, Macrochelys Temminckii
The alligator snapping turtle (Macrochelys temminckii) is a long-lived species that merits reintroduction because the species has declined significantly throughout its range. The purposes of this study were to: 1) report the findings of a reintroduction project that was initiated in 2008 and 2) to …

Effect of Ingestion by Alligator Snapping Turtles (Macrochelys Temminckii) on Seeds of Riparian Vegetation
<p>The alligator snapping turtle (Macrochelys temminckii) is a large freshwater turtle that inhabits many lotic water bodies in the Southeastern United States. The species consumes primarily fish but also consumes large amounts of vegetation including seeds of common persimmon (Diospyros …

Diet and Feeding Behavior of Juvenile Alligator Snapping Turtles (Macrochelys Temminckii) in Eastern Oklahoma
In Oklahoma, the alligator snapping turtle (Macrochelys temminckii) has experienced declines and recent efforts to conserve the species have focused on reintroducing captive-reared juveniles. The effect of the reintroduction on other aquatic turtles is not known and feeding behavior of juvenile M. …

Detection, Occupancy, Abundance, and Mercury Accumulation of the Alligator Snapping Turtle (Macrochelys temminckii) in Texas
… (<em>Macrochelys temminckii</em>,<em> </em>i.e., alligator snapping turtle) within the southwestern periphery of its distribution. Hierarchical modeling suggested the distribution of the species is more affected by watershed-scale land-cover than local habitat, and provided a baseline estimate of …

Sensitivity analysis and calibration of the alligator cracking model in the mechanistic-empirical pavement design guide using regional data
… the data from all across the United States. The alligator cracking model uses traffic, material and structural data along with local and global calibration factors to calculate the number of axles to failure and the damage index. Both of which are further used to calculate the fatigue cracking in …
