Applications for Fall 2024 are closed for this project.
Studying vertebral measurements and trabeculae's shape and orientation can provide a more comprehensive understanding of how rodent groups adapted to their specific environments and lifestyles. Quantifying the gross morphological variation of each rodent group through vertebral measurements can provide information about weight-bearing capacity, stability, strength, mobility, and flexibility. Additionally, by studying the shape and orientation of trabeculae under different conditions, we can gain insights into the mechanical properties of the bone and how it responds to mechanical stimuli. This information can help us better understand the biomechanics of different rodent vertebrates and how they have adapted to their ecological niche over time. These quantitative correlational analyses can reveal essential relationships between rodent vertebral morphology and their specific environments and lifestyles, ultimately leading to a more comprehensive understanding of the functional and evolutionary adaptations of the vertebral column in different rodent groups.
This study investigates the influence of ecological niche on vertebral morphology in rodents by analyzing external and internal measurements of the cervical, thoracic, and lumbar regions. The study compares the vertebral morphological measurements and regionalization in arboreal, fossorial, and terrestrial rodents. The study aims to understand how ecological niche affects the functional and evolutionary adaptations of the vertebral column in different rodent species.
Role: URAP students will utilize CT data and applied quantitative methods to process computed tomography (CT) image data, construct 3-D skull models, and engage in 3D visualization. They will also gain expertise in biomechanics and other related skills essential for their research on the influence of ecological niches on rodent vertebral morphology. These cutting-edge techniques will empower the students to explore and analyze intricate structural adaptations in the vertebral columns of rodents, enhancing our understanding of their functional and evolutionary responses to different ecological niches.
Qualifications: The desired qualifications for this role include a strong background in biology, anatomy, or a related field, focusing on vertebrate morphology or biomechanics. Prior experience in CT image data processing, 3D modeling, 3D printing, and visualization techniques will be advantageous—proficiency in Avizo, 3D Slicer, and related CT visualization. Ideal candidates should be keenly interested in ecological adaptations and evolutionary biology, particularly in rodents. Strong analytical and problem-solving skills and attention to detail are crucial for accurate vertebral measurements and trabecular analysis. Additionally, excellent communication and teamwork abilities are desirable to collaborate effectively with researchers.
