Unbridled Insights: Exploring Equine Behavior Through Gps Tracking And Analysis, Madison L. Philbrick Dec 2023

Unbridled Insights: Exploring Equine Behavior Through Gps Tracking And Analysis, Madison L. Philbrick

Electronic Theses and Dissertations

Horse behavior in pasture and grazing environments remains understudied, despite the substantial domestic horse population in the United States. This paper explores the utilization of Global Positioning System (GPS) technology to detect equine behavior, specifically focusing on grazing behaviors. By analyzing GPS data from (n=9) Standardbred horses, this study aims to establish the capabilities and accuracy of the Columbus P-1 data logger as a low-cost GPs unit for equine research, without the use of accelerometers. Through the data provided by the GPS unit, a model to distinguish grazing, resting, drinking, walking, trotting, and running was developed with satisfactory detection rates. …


I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy Apr 2023

I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy

Honors College

Littorina littorea is an intertidal, invasive gastropod species common in the Gulf of Maine. In this paper, I studied the avoidance and risk-reducing behavioral responses of L. littorea to predation risk by invasive crustacean species Carcinus maenas. Avoidance and risk-reducing behavior in this study are defined by the tendency to move towards the edge and out of a simulated tide pool and the tendency to reduce feeding. The goal of this study was to determine whether the exposure to chemical cues of predators resulted in an increase in avoidance behavior, risk-reducing behavior, and a reduction in the time before the …


Quantifying Equine Behavior Utilizing Gps, Vanessa M. Cote May 2022

Quantifying Equine Behavior Utilizing Gps, Vanessa M. Cote

Honors College

GPS tracking systems have been around for many years and are used to track, map, determine precise locations, navigate, and get precise time measurements on a number of different animals, devices, vehicles, and much more. The use of GPS tracking systems on animals has been a huge breakthrough in the cattle industry since this means farmers no longer have to monitor their cattle manually, but can do remotely. The research that has previously been done on cattle tracking can now be applied to horses, although as horses are used in a much different manner than cattle the data will go …


The Impacts Of Embryonic Arsenic Exposure Of Fundulus Heteroclitus, Torey Bowser Aug 2021

The Impacts Of Embryonic Arsenic Exposure Of Fundulus Heteroclitus, Torey Bowser

Electronic Theses and Dissertations

Arsenic is a toxic metalloid that exceeds safe drinking water standards in groundwater in many locations worldwide. Arsenic exposure in fish has been linked to destruction of gill tissues, impairment of growth, decreased muscle mass, memory impairment, increased aggression, and avoidance behaviors. We examined the behavior of mummichogs (Fundulus heteroclitus) following arsenic exposure during development in two studies. Embryos were collected from fish from three reference sites: Scorton Creek (SC), Massachusetts, Wells Harbor (WE), Maine, and Block Island (BLOC), Rhode Island and two contaminated sites: Callahan Mine (CM), Brooksville, Maine, and New Bedford Harbor (NBH), Massachusetts. Embryos were …


Territorial Aggression Increases Along An Urban Gradient In Resident But Not Migratory Song Sparrows, Darlene Turcotte Apr 2014

Territorial Aggression Increases Along An Urban Gradient In Resident But Not Migratory Song Sparrows, Darlene Turcotte

Honors College

During the breeding season, birds behave more aggressively toward rivals to maintain and defend territories. Resident birds are thought to be more aggressive than migratory birds because they need to maintain a territory year round. Furthermore, birds in urban environments can exhibit more aggressive behaviors than their rural counterparts because of the bolder behavioral characteristics required to colonize urban habitats. In this study, we investigated how migration strategy and landscape composition interact to affect territory defense in two subspecies of Song Sparrow (Melospiza melodia). To evoke an aggressive response, we simulated invasions by broadcasting songs from within a …


Foraging Behavior Of Eastern Gray Squirrels On The University Of Maine Campus, Aimee Young May 2013

Foraging Behavior Of Eastern Gray Squirrels On The University Of Maine Campus, Aimee Young

Honors College

The goal of this study was to observe the foraging behavior of Eastern Gray Squirrels (Sciurus carolinensis) on the University of Maine campus. The study tested whether squirrels in a more urban setting followed the optimal foraging theory, or if rarity of a food type played a greater factor in food selection. The study also examined whether urban squirrel behavior mimicked that of wild squirrels when presented with a food type uncommon on campus, but common in other parts of Maine, specifically the acorns of the white oak tree (Quercus alba). In three different areas on the campus, squirrels were …
