“…Maybe most importantly for this thesis, muscle and bone histology and function have been studied (Aerts et al, 2023b;Alvarenga et al, 2013;Andersen et al, 2016;Magrini et al, 2023;Vanden Hole et al, 2018b). Results vary, indicating differences in locomotor performance and muscle mass, but failing to associate them with differences in fibre composition or force generating capacity.…”

We study piglet locomotion, attempting to falsify a difference that is due to birth weight category.This requires a methodological foundation on topics unfamiliar to most Biologists (Fourier Analysis, probabilistic models), which I introduce in dedicated chapters._Part I: Kinematic Analysis_+ I will introduce Fourier Methods with a practical guide and review its occurrence specifically in the field of locomotor biomechanics (Ch. 2).+ The power of Fourier tools is then unleashed onto a large cross-species study that covers most of the ungulate clade (Ch. 3, Mielke et al., 2019)._Part II: Probabilistic Modeling_+ Processing complex kinematic data, I will introduce the basics of probabilistic modeling (Ch. 4) in a "tiny textbook of statistics"...+ ... before turning around the conventional modeling strategy and applying it to piglets (Ch. 5, Mielke et al., 2023)._Part III: Dynamics_+ Kinematics are just half of locomotor research: the study of forces and moments is reviewed and summarized in another overview chapter (Ch. 6).+ To calculate joint moments, one needs to measure inertial properties, yet it turns out that these are not trivial to retrieve from x-ray tomographic images (Ch. 7).The thesis closes with a general discussion to round up and project the presented work to potential future applications (Ch. 8).

Developmental milestones in captive Galago moholi

Systems of the body develop in a modular manner. For example, neural development in primates is generally rapid, whereas dental development varies much more. In the present study, we examined development of the skull, teeth, and postcrania in a highly specialized leaping primate, Galago moholi. Eighteen specimens ranging from birth to adult were studied. Bones, teeth, and the cranial cavity (i.e., endocast) were reconstructed with Amira software based on microCT cross‐referenced to histology. Amira was also used to compute endocast volume (as a proxy for brain size). Reconstructions of the wrist and ankle show that ossification is complete at 1 month postnatally, consistent with the onset of leaping locomotion in this species. Endocranial volume is less than 50% of adult volume at birth, ~80% by 1 month, and has reached adult volume by 2 months postnatal age. Full deciduous dentition eruption occurs by 2 weeks, and the young are known to begin capturing and consuming arthropods on their own by 4 weeks, contemporaneous with the timing of bone and ankle ossification that accompanies successful hunting. The modular pattern of development of body systems in Galago moholi provides an interesting view of a “race” to adult morphology for some joints that are critical for specialized leaping and clinging, rapid crown mineralization to begin a transitional diet, but perhaps more prolonged reliance on nursing to support brain growth.

Developmental factors influencing bone strength in precocial mammals: An infant pig model

Abstract: Most vertebrates are precocial in locomotion, able to walk and run soon following birth. This is proposed to have evolved as the basal condition, as a response to high levels of predation upon infants and
