MODELLING OF ALLOMETRIC EQUATIONS FOR BIOMASS ESTIMATE IN DECIDUOUS FOREST
FLORESTA, 2018 This paper aimed at testing and adjusting the allometric models for the biomass estimate in deciduous forest. The data result from seven 12 x 12 m plots, where 91 trees were cut down. Their diameter at breast height (DBH) was greater than 5 cm, and the measurement was made based on the DBH, total height (H) and total dry biomass (DAB) for each ...

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians
The 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

Humans and platyrrhines share a pattern of articular variance
The Anatomical Record, EarlyView.Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals
The Anatomical Record, EarlyView.Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

BIOMASS ALLOMETRY FOR TREE SPECIES OF NORTHWESTERN MEXICO
Tropical and Subtropical Agroecosystems, 2010 Tree biomass plays a key role in sustainable forest management since it is the basis for estimating stocks and fluxes of several biogeochemical elements, the amount of energy stored in biomass, and other conventional goods and services.

The Anatomical Record, EarlyView.Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

The Anatomical Record, EarlyView.Abstract This study, alongside prior work on crab‐eating macaques with O'Higgins, investigates regional variation in skull sexual dimorphism across different species of Old World monkeys. Findings reveal consistent patterns: the posterior skull regions (mandibular vertical ramus, chondrocranium and, possibly, the cranial vault) exhibit lower dimorphism,

Cristid obliqua morphology as a correlate of diet in lorisoids
The Anatomical Record, EarlyView.Abstract Methods for elucidating dietary patterns from dental morphology have provided much insight into molar form, function, and diet in extinct taxa. However, many methods rely on the collection of homologous landmarks (like shearing crest lengths), or computationally intensive and nuanced metrics that capture shape (like dental topography). Here, a
