... component analysis (PCA). Each line represents a single feeding strike and points along them are consecutive cranial shapes at different stages of the motion. Note that in this plot, the subject of alignment was not individual cranial shapes, as is traditionally done in geometric morphometrics...

... 3D geometric morphometrics and quantitative data on cranial muscles [mass, fiber length and physiological cross-sectional area (PCSA)], we investigated the relationships between skull shape, jaw musculature and bite force of 28 species of caecilian amphibians. As shape variation in the cranium...

... described, relationships between form and function remain poorly understood. In the present study, we explored the relationship between cranial shape and in vivo burrowing forces. Using micro-computed tomography (µCT) data, we performed 3D geometric morphometrics to explore whether cranial and mandibular...

... fox ( Vulpes vulpes ). We performed dissections and used 3D geometric morphometric approaches to quantify jaw shape in 68 foxes. We used a static lever model and bite force estimates were compared with in vivo measurements of 10 silver foxes. Our results show strong relationships exist between cranial...

...Dušan Devetak; Jan Podlesnik; Inon Scharf; Tina Klenovšek ABSTRACT Pit-building antlion larvae are predators that construct pitfall traps in fine sand. We used three-dimensional laser scanning and geometric morphometrics to reveal the shape of antlion pits of two antlion species, analysed...

... the laryngeal size or shape of B. taylori mice was sexually dimorphic using a geometric morphometric (GM) approach. 3D surfaces of three male and three female laryngeal cartilages were used to quantify shape using curve and surface landmarks. Landmarks were placed on surface renderings using the ‘geomorph...

.... Adaptive plasticity Geometric morphometrics Bone microarchitecture Trabecular architecture Plasticity allows an organism to ‘fine-tune’ its form to best fit its behavior and is thought to be important at the macroevolutionary scale ( West-Eberhard, 1989 , 2005 ; Scheiner, 1993 ; Agrawal, 2001...

... premaxilla bones of the upper jaw develop abnormally. However, ∼50% of bat species have natural, non-pathological cleft palates. We used the family Vespertilionidae as a model and linear and geometric morphometrics within a phylogenetic framework to (1) explore evolutionary patterns in cleft morphology...

... geometric morphometrics to test the effect of different damage distributions on flight performance. Our results show that impaired flight performance clearly depends on damage location over the wings, pointing to a relative importance of different wing parts for flight. A deteriorated forewing leading edge...

... to be more aggressive. We found that bite force was higher in X*Y females than in other females and males. We then performed geometric morphometric analyses on their skulls and mandibles and found that the higher performance of X*Y females was mainly explained by a greater overall skull size. The effects...
