Binoculars To Bytes: Development And Field Validation Of An Ai-Driven System For Avian Monitoring, Christian J. Dupree
Graduate Student Theses, Dissertations, & Professional Papers
Autonomous camera-trap arrays coupled with artificial-intelligence (AI) vision can lift bird monitoring beyond the spatial, temporal, and labor limits of traditional field surveys. We present Binoculars to Bytes (B2B), an open-source pipeline that turns 180–360° time-lapse imagery into analysis-ready avian data. At Freezout Lake Wildlife Management Area (Montana, USA) the system ran four-hour morning deployments during spring and fall migrations (2023–2024). A YOLO-NAS detector, incrementally refined with a “Specialized Localized Iterative Model” workflow, quadrupled local accuracy and, after confidence-based species-binning, cut false-positive rates in half. Daily AI species lists were benchmarked against contemporaneous eBird citizen-science checklists and recovered ≥ …

Investigating The Presence Of Individuality And Behavioral Syndromes In Northern Cottonmouths (Agkistrodon Piscivorus), Joshua Lowy
Graduate Theses/Dissertations
Within the last 15 ̶20 years, research on behavioral syndromes has seen a surge in prominence and popularity in behavioral ecology, revealing that many animals exhibit individually consistent behavioral tendencies. Behavioral syndromes occur when behavioral traits are correlated with one another within the same context or across different contexts. Despite new appreciation for the ecological, evolutionary, and conservation implications of behavioral syndrome data, the taxonomic breadth of studies is uneven. Snakes are underrepresented within squamate reptiles and, among venomous species, only two rattlesnakes (Crotalus) have been investigated for evidence of behavioral syndromes. My study investigates individuality and the presence of …

Star-Studded Stingers: Fluorescent Sensilla On The Scorpion Aculeus (Arachnida: Scorpiones), Graeme Lowe
Star-Studded Stingers: Fluorescent Sensilla On The Scorpion Aculeus (Arachnida: Scorpiones), Graeme Lowe
Euscorpius
The aculeus of the scorpion telson was studied by UV fluorescence microscopy. Numerous brightly fluorescent punctae were observed on the non-fluorescent distal aculeus, including the tip region. The punctae were identified as aculear sensilla coeloconica (ASC), and were connected to fluorescent canals running through the cuticle. ASC were present in both sexes, and in adults and immatures as early as the second juvenile instar, but were absent from the first instar. The distal aculeus was found to be encased in a thick, non-fluorescent dark exocuticle (DX), covering an underlying thin, fluorescent hyaline exocuticle (HX). Fluorescent ASC were recorded from 183 …
Social Learning And Cultural Enrichment For Fish Welfare, Chiawen Chiang, Becca Franks
Social Learning And Cultural Enrichment For Fish Welfare, Chiawen Chiang, Becca Franks
Animal Sentience
This commentary examines how understanding animal culture—shared behaviors and knowledge transmitted through social learning—plays a role in advancing welfare practices for captive fishes. Despite extensive evidence of fishes' complex sociocultural capacities, their psycho-social needs remain underestimated and unmet in zoos and aquaria. We explore what considering fish culture might mean for welfare practices: diverse social learning opportunities, cultural development, and thoughtful group management. More knowledge about wild fishes' lives will help bridge the gap between their full, complex lives and current captive welfare practices.

Technological Accessibility For Wildlife Telemetry Research, Andrew Danielson
Technological Accessibility For Wildlife Telemetry Research, Andrew Danielson
The Journal of Purdue Undergraduate Research
Over the course of two years, I conducted original research into improving accessibility for researchers in the field of wildlife telemetry. Wildlife telemetry is a technique used by biologists to track wildlife in the field, which requires the biologist to attach a small radio transmitter to an animal, usually using a specially designed collar, harness, or another means. These transmitters are battery powered and will emit or transmit a regularly timed radio signal that can be received by radio receivers carried by the researchers. Two issues faced by wildlife telemetry researchers are the cost of wildlife telemetry equipment and the …

Study Of The Brain Anatomy Of Three Extinct Marsupials: Thylacinus Cynocephalus, Thylacoleo Carnifex, And Silvabestius Johnnilandi, Francisco Garcia
Honors Program Theses and Research Projects
Marsupials are pouched mammals that today are mainly found in Australasia and South America. Marsupials have proven to be quite intriguing to evolutionary biologists who note how some marsupials resemble placentals in anatomy due to convergent evolution, with both marsupials and placentals filling similar niches in their respective environments. As of today, studies interested in marsupial brain evolution have published descriptions of cranial endocasts for several species of marsupials, with the number of descriptions seeing a massive boost over the last 20 years with the arrival of CT imaging technology. However, no comprehensive study of brain evolution in marsupials has …
Climate Change Affecting Waterfowl Migration, Destiny Fox
Climate Change Affecting Waterfowl Migration, Destiny Fox
D.U.Quark
Climate Change is a major environmental factor in waterfowl migration patterns. Migratory waterfowl are species of birds that live in or around wetlands, mainly including lakes, streams, and marshes. Contaminated bodies of water at stopover sites during migratory seasons can lead to death among many species of waterfowl, as well as water borne diseases from snail eggs. Changing environmental factors can also lead to negative effects on the bird’s ability to forage properly. These environmental factors include the evaporation of several wetlands that have led to waterfowl foraging in local farmers’ land. Focusing more heavily on improving satellite tracking could …

Spatial Ecology Of Large Bodied Ichthyofauna In The Red River Of The North Basin, William Marshall Stuart
School of Natural Resources: Dissertations, Theses, and Student Research
Understanding spatial patterns and processes is essential for designing research studies, implementing management actions, and planning restoration efforts. The Red River of the North basin spans a broad geographic area where jurisdictional oversight is divided among several entities (Manitoba, CAN; North Dakota, USA; Minnesota, USA; South Dakota, USA), creating a mosaic of regulatory and functional process zones. Understanding the spatial ecology of freshwater fishes in this disjointed landscape is essential to address diverse life history requirements and the movement constraints imposed by anthropogenic structures. Long-term acoustic telemetry revealed that large bodied ichthyofauna employ a diverse range of movement strategies (i.e., …
