Fig. 3 Bolus size measurement. This figure depicts the method used to measure bolus size in visible swallows. Light yellow outlines highlight the cross-sectional area of each bolus, which was converted to mm² after calibration with stainless steel neck collar balls. The bolus lengths provide a visual reference for size but were not used for formal measurements in this study. The animals were habituated to wearing the very light neck collar, which did not appear to affect their posture, natural swallowing behavior, or bolus estimation, even with slight superposition as observed in marmoset F9.

I'm recruiting a PhD student to join the lab at @gtsciences.bsky.social in Fall 2026! Broad taxonomic and topical freedom under the umbrella of vertebrate joint form and function. Information here: www.manafzadeh.com – please share 🦴🩻

New paper out in Pediatric Research! We found that feeding in infant pigs raised on a ducted, biomimetic nipple more closely resembled the mechanics of breastfeeding, and that differences in nipple design impacted milk acquisition and overall feeding performance 🐷🍼

Our new paper led by recent lab alumni Hannah Shideler and postdoc Elska Kaczmarek is out in ICB @sicbjournals.bsky.social! For the first time ever, we reconstructed the volume of the oral cavity during suckling, and found that nipple design impacts tongue function.

The Mayerl Lab at NAU is looking to recruit a PhD student for Fall 2026! We take an integrative approach that bridges engineering, clinical, and evolutionary approaches to study feeding physiology of vertebrates. Our lab website is linked in our bio, and feel free to reach out on here or via email.
