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.

Local variation in age‐related cortical expansion within and between cross‐sections of distal human long bones

open access: yesThe 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 ...

Allometric Models of Aboveground Biomass in Mangroves Compared with Those of the Climate Action Reserve Standard Applied in the Carbon Market

open access: yesResources
The standardized methods used in carbon markets require measurement of the biomass and carbon stored in trees, which can be quantified through allometric equations.

Robust Estimation of the Vertical Structure of Forest with Coherence Tomography [PDF]

open access: yes, 2011
In the last decade, the accurate and reliable estimation of forest biomass has gained increasing attention within the SAR remote sensing community, given its crucial role in terrestrial carbon budget. First approaches for biomass estimation were based on

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.

Development of Local Allometric Equation to Estimate Total Aboveground Biomass in Papua Tropical Forest [PDF]

open access: yes, 2016
Recently, pantropical allometric equations have been commonly used across the globe to estimate the aboveground biomass of the forests, including in Indonesia. However, in relation to regional differences in diameter, height and wood density, the lack of

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

open access: yesThe Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Allometric relationships of growth rate and fruit number.

open access: yes, 2019
(A) Allometric relationship between growth rate and vegetative plant dry mass M fitted with a power-law function with mass-corrected exponent (g[M]). Equation fitted separately on 451 accessions (red dots, solid line) and 447 hybrids (blue dots, dashed ...

Allometric equations, stem density and biomass expansion factors for Cryptomeria japonica in Mount Halla, Jeju Island, Korea

open access: yesJournal of Ecology and Environment, 2014
This study was conducted to develop allometric equations and to determine the stem density and biomass expansion factor (BEF) for the estimation of the aboveground and belowground biomass of Cryptomeria japonica in Jeju Island, Korea.
