Which Drone Should You Buy To Study Dolphins?: Assessing Dolphin Response Behavior At Various Heights With Commonly Used Platforms, Savannah Damiano

Graduate Research Conference

Drones are becoming a commonly used platform for understanding dolphin behavior However, this can be an intimidating field to approach as data is sparse on which commonly used drone types are the best to use for marine mammal research.

There is a need to further investigate the advantages and disadvantages of various drone types for marine mammal studies when it comes to disturbance factors.

Three commonly used DJI drone platforms were used to evaluate how drones affect the behavior of dolphins, the DJI Mini 2 the DJI Mavic 2 Enterprise Advanced, and the DJI Inspire 2.

The DJI Mavic Enterprise …

Contrasting Orthophotos By Height, Overlap, And Drone, Edward Ironsmith

Graduate Research Conference

Drones have recently become a mainstay for surveying and modeling of small areas of land in a cost-efficient manner. Yet there are many variables that affect the time, quality, and cost of capturing and generating such products. We look at several of these parameters and discuss the alternatives to minimize cost over a series of projects. The parameters in question include height, overlap, sensor resolution, processing time, drone costs, computer costs, processing costs, time in the field, storage, drone endurance and the likelihood of costly delays. A series of flights using different drones and flight parameters were then used to …

Demography Of Alligator Snapping Turtles (Macrochelys Temminckii) Across A Fishing Pressure Gradient, Luke Micek

Graduate Research Conference

Demographic data are necessary to predict population responses to environmental and anthropogenic stressors and inform conservation efforts for declining species (Weimerskirch 2018, J.Wildl. Manag.).

The western alligator snapping turtle (Macrochelys temminckii; hereafter AST; Fig. 5) is the largest species of freshwater turtle in North America and is being considered for Federal listing as a Threatened Species under the Endangered Species Act (Federal Register 2021). Notably, there is a lack of demographic data of AST in Texas.

Passive fishing gear (i.e., trotlines) have been identified as a pervasive threat to AST populations, although this threat has yet to be quantified inTexas …

Seasonal Dynamics And Glycerol-3-Phosphate Dehydrogenase Variability In Ixodes Scapularis Tick Population In Eastern Texas, Daniela Soto

Graduate Research Conference

Objectives: 1. Document seasonal population dynamics of I. scapularis in eastern Texas. 2. Explore variability of GPDH in I. scapularis ticks in eastern Texas and relate data to its population dynamics.
