The mechanism of labor in nonhuman primates: A look inside
The Anatomical Record, EarlyView.Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

The Anatomical Record, EarlyView.Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

The Anatomical Record, EarlyView.Abstract Cortical bone expansion is an age‐related process where, through endosteal resorption and periosteal apposition, cross‐sectional diameter increases while cortical thickness decreases in long bone diaphyses. Local variation has been observed in this process between cross‐sectional locations, but few studies have examined directional variation ...

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)
The Anatomical Record, EarlyView.Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

Seasonal dimorphism and winter chilling stress in Thymus sibthorpii
, 2014 Seasonal dimorphism (summer/winter) has been so far studied only in a few plants and has been focused on summer drought stress. However, Thymus sibthorpii in the study area appears to be affected by winter chilling stress and not by summer drought stress.

Evaluating Bergmann's and Allen's rules in the long bones of the eastern gray squirrel
The Anatomical Record, EarlyView.Abstract Ecogeographical rules predict variation in body size and appendage proportions across climatic gradients, yet intraspecific tests using long bones from wild populations remain limited among small mammals. This study tests the hypothesis that eastern gray squirrels (Sciurus carolinensis) conform to Bergmann's rule, that is, body size increases ...
