The pelvis doesn't walk by itself: Wider pelves reduce the cost of walking over unstable surfaces

open access: yesThe Anatomical Record, EarlyView.
Abstract Walking over variable and/or unstable terrain is a key aspect of daily life and was crucial to the evolution of bipedalism. The ability to find gait solutions that maintained stability over uneven terrain for the least increase in metabolic cost was likely a hallmark of locomotor effectiveness in early humans, in particular acting as an ...

Genetic Variability in Distinct Genotypes of Forage Pearl Millet (Pennisetum glaucum (L.) R. Br.) for Forage Yield and Forage Yield Attributing Traits

open access: yesInternational Journal of Economic Plants
The experiment was conducted during kharif (July–October, 2023) at Centre for Forage Research, S. D. Agricultural University, Sardarkrushinagar, Gujarat, India to study to appraise genetic variability in pearl millet genotypes for fodder yield and associating traits. Thirty forage pearl millet genotypes were evaluated for genetic parameters in terms of

What can be deduced from a debate on self-supplied forage milk yield per unit of land area? [PDF]

open access: yes, 2016
The purpose of this study is to calculate the self-supplied forage milk yield-necessary to promote dairy management based on self-supplied forage - from actual survey data, and to study the self-supplied forage milk yield per unit of land area, which is ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)

open access: yesThe 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.

Evaluating Bergmann's and Allen's rules in the long bones of the eastern gray squirrel

open access: yesThe 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 ...
