Tilapias raised in complex environments developed sagittae with increased length, thickness, area and volume. However, auditory sensitivity was consistent across...

... Summary: The sixbar distichodus is a freshwater, plant-eating fish with an extra joint in its lower jaw that allows it to feed in new ways compared with fishes lacking the joint. Innovation Functional morphology Geometric morphometrics Kinematics Novelty University of California, Davis...

... force data presented by Herrel et al. (2019) suggest that the jaw-closing system may be different across caecilians, yet little is known about variation in the jaw muscles and its impact on bite force. Using 3D geometric morphometrics and quantitative data on cranial muscles [mass, fiber length...

... 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...

... 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...
