Skeletal morphology is important in evolutionary, genetic, developmental, physiological, and functional studies. Although samples from free‐ranging individuals may be preferable, constraints of sample size, demography, or conservation status may necessitate the inclusion of captive‐born individuals. Captivity may be associated with physical, physiological, or behavioral differences that may affect skeletal form. This study assesses differences in postcranial skeletal form between free‐range and captive‐born
Primate craniofacial growth is traditionally assumed to cease upon maturation or at least be negligible, whereas bony remodeling is typically associated with advanced adult age and, in particular, tooth loss. Therefore, size and shape of the craniofacial skeleton of young and middle‐aged adults should be stable. However, research on both modern and historic human samples suggests that portions of the

ABSTRACT andMacaca mulatta . Samples included free‐rangeSaguinus oedipus from Cayo Santiago (Caribbean Primate Research Center) and captive‐born macaques from the Wisconsin National Primate Research Center.M. mulatta samples included free‐range born and captive‐born individuals from the Oak Ridge Associated Universities Marmoset Research Center. Twenty‐four dimensions of various bones, including the scapula, upper limb, innominate and lower limb, were recorded for adults. Age of epiphyseal closure was recorded for immature captive‐bornS. oedipus . Analysis of variance and principal component analyses tested significant differences between free‐range born and captive‐born individuals in each species. Significant differences were present in size and shape of postcrania between free‐range and captive‐born within taxa. Free‐range macaques were larger than captive‐born macaques, but this pattern did not consistently carry over to theM. mulatta Saguinus samples. Shape differences, while present throughout the skeleton, were especially prominent in the scapula. Differences in developmental timing, nutrition, and physical activity can be expected to contribute to the observed differences in postcranial skeletal form. These differences should be considered when captive‐born primates are included in morphological or evolutionary studies. Anat Rec, 2018. © 2018 Wiley Periodicals, Inc.

Abstract Due to small body size, an immature musculoskeletal system, and other growth‐related limits on performance, juvenile mammals frequently experience a greater risk of predation than their adult counterparts. As a result, behaviorally precocious juveniles are hypothesized to exhibit musculoskeletal advantages that permit them to accelerate rapidly and evade predation. This hypothesis was tested through detailed quantitative evaluation of muscle growth in wild Eastern cottontail rabbits (
Sylvilagus floridanus ). Cottontail rabbits experience high rates of mortality during the first year of life, suggesting that selection might act to improve performance in growing juveniles. Therefore, it was predicted that muscle properties associated with force and power capacity should be enhanced in juvenile rabbits to facilitate enhanced locomotor performance. We quantified muscle architecture from 24 paravertebral and hindlimb muscles across ontogeny in a sample of n =MM ), physiological cross‐sectional area (PCSA ), isometric force (F max), and instantaneous power (P inst), along with several dimensionless architectural indices. In contrast to our hypothesis,MM andPCSA for most muscles change with positive allometry during growth by scaling atand , respectively, whereas F maxandP instgenerally scale indistinguishably from isometry, as do the architectural indices tested. However, scaling patterns indicate that the digital flexors and ankle extensors of juvenileS. floridanus have greater capacities for force and power, respectively, than those in adults, suggesting these muscle properties may be a part of several compensatory features that promote enhanced acceleration performance in young rabbits. Overall, our study implies that body size constraints place larger, more mature rabbits at a disadvantage during acceleration, and that adults must develop hypertrophied muscles in order to maintain mechanical similarity in force and power capacities across development. These findings challenge the accepted understanding that juvenile animals are at a performance detriment relative to adults. Instead, for prey–predator interactions necessitating short intervals of high force and power generation relative to body mass, as demonstrated by rapid acceleration of cottontail rabbits fleeing predators, it may be the adults that struggle to keep pace with juveniles. -
Abstract We compared the head skeleton (skull and lower jaw) of juvenile and adult specimens of five snake species [
Anilios (=Ramphotyphlops )bicolor ,Cylindrophis ruffus ,Aspidites melanocephalus ,Acrochordus arafurae , andNotechis scutatus ] and two lizard outgroups (Ctenophorus decresii ,Varanus gilleni ). All major ontogenetic changes observed were documented both qualitatively and quantitatively. Qualitative comparisons were based on high‐resolution micro‐CT scanning of the specimens, and detailed quantitative analyses were performed using three‐dimensional geometric morphometrics. Two sets of landmarks were used, one for accurate representation of the intraspecific transformations of each skull and jaw configuration, and the other for comparison between taxa. Our results document the ontogenetic elaboration of crests and processes for muscle attachment (especially for cervical and adductor muscles); negative allometry in the braincase of all taxa; approximately isometric growth of the snout of all taxa exceptVaranus andAnilios (positively allometric); and positive allometry in the quadrates of the macrostomatan snakesAspidites ,Acrochordus andNotechis , but also, surprisingly, in the iguanian lizardCtenophorus . Ontogenetic trajectories from principal component analysis provide evidence for paedomorphosis inAnilios and peramorphosis inAcrochordus . Some primitive (lizard‐like) features are described for the first time in the juvenileCylindrophis . Two distinct developmental trajectories for the achievement of the macrostomatan (large‐gaped) condition in adult snakes are documented, driven either by positive allometry of supratemporal and quadrate (in pythons), or of quadrate alone (in sampled caenophidians); this is consistent with hypothesised homoplasy in this adaptive complex. Certain traits (e.g. shape of coronoid process, marginal tooth counts) are more stable throughout postnatal ontogeny than others (e.g. basisphenoid keel), with implications for their reliability as phylogenetic characters. -
Abstract Objectives A number of studies have demonstrated the ontogenetic plasticity of long bone diaphyseal structure in response to mechanical loading. Captivity should affect mechanical loading of the limbs, but whether captive apes grow differently than wild apes has been debated. Here, we compare captive and wild juvenile and adult
Gorilla to ascertain whether growth trajectories in cross‐sectional diaphyseal shape are similar in the two environments.Materials and methods A sample of young juvenile (
n = 4) and adult (n = 10) captive specimens, with known life histories, were compared with age‐matched wildGorilla gorilla gorillaG.g. gorilla (n = 62) andG. beringei beringei (n = 75) in relative anteroposterior to mediolateral bending strength of the femur, tibia, and humerus. Cross sections were obtained using peripheral quantitative CT.Results Captive and wild adult
G.g. gorilla differed in bending strength ratios for all three bones, but these differences were not present in young juvenileG.g. gorilla . In comparisons across taxa, captive juvenileG.g. gorilla were more similar to wildG.g. gorilla than toG.b. beringei , while captive adultG.g. gorilla were more similar in shape toG.b. beringei in the hind limb.Discussion Captive and wild
follow different ontogenetic trajectories in long bone diaphyseal shape, corresponding to environmental differences and subsequent modified locomotor behaviors. Differences related to phylogeny are most evident early in development.G. gorilla -
Abstract In infancy, maternal socioeconomic status (
SES ) is associated with real‐time language processing skills, but whether or not (and if so, how) this relationship carries into adulthood is unknown. We explored the effects of maternalSES in college‐aged adults on eye‐tracked, spoken sentence comprehension tasks using the visual world paradigm. When sentences ended in highly plausible, expected target nouns (Exp. 1), higherSES was associated with a greater likelihood of considering alternative endings related to the action of the sentence. Moreover, for unexpected sentence endings (Exp. 2), individuals from higherSES backgrounds were sensitive to whether the ending was action‐related (plausible) or unrelated (implausible), showing a benefit for plausible endings. Individuals from lowerSES backgrounds did not show this advantage. This suggests maternalSES can influence the dynamics of sentence processing even in adulthood, with consequences for processing unexpected content. These findings highlight the importance of early lexical experience for adult language skills.
