Incomplete specimens in geometric morphometric analyses [PDF]
Methods in Ecology and Evolution, 2013 Summary The analysis of morphological diversity frequently relies on the use of multivariate methods for characterizing biological shape. However, many of these methods are intolerant of missing data, which can limit the use of rare taxa and hinder the study of broad patterns of ecological diversity and morphological evolution.

Variation in parrot jaw musculature
The Anatomical Record, EarlyView.Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Measuring 3D shape in orthodontics through geometric morphometrics
Progress in Orthodontics, 2017 Background Geometric morphometrics (GMM) has been traditionally applied to the field of biology to study developmental differentiations between species. Orthodontics deals with the shape and size of the face and its components.

The relationship between form and function of the carnivore mandible
The Anatomical Record, EarlyView.Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

The Anatomical Record, EarlyView.Abstract Bats possess the remarkable ability to fly, and with this, distinctive wing bone properties. We investigated the structural, mechanical, and compositional properties of the humerus, radius, metacarpals, and proximal and middle phalanges of Carollia perspicillata, an approximately 15 g fruit‐eating bat native to the Neotropics.

Distal femoral morphology as a risk factor for osteoarthritis
The Anatomical Record, EarlyView.Abstract Osteoarthritis (OA) is a leading cause of disability affecting millions of adults in the United States, commonly resulting in the need for total knee arthroplasty (TKA) to restore mobility and quality of life. This study investigates potential differences in baseline distal femoral shape between individuals who received TKA due to OA and a ...
