Fused Traditional and Geometric Morphometrics Demonstrate Pinniped Whisker Diversity
Vibrissae (whiskers) are important components of the mammalian tactile sensory system, and primarily function as detectors of vibrotactile information from the environment. Pinnipeds possess the largest vibrissae among mammals and their vibrissal hair shafts demonstrate a diversity of shapes. The vibrissae of most phocid seals exhibit a beaded morphology with repeating sequences of crests and t...
متن کاملGeometric Morphometrics
The field of morphometrics is developing quickly and recent advances allow for geometric techniques to be applied easily to many zoological problems. This article briefly introduces geometric morphometric techniques and then reviews selected areas where those techniques have been applied to questions of general interest. This article is relevant to non-specialists looking for an entry into geom...
متن کاملGeometric morphometrics and phylogeny
This paper reviews some of the important properties of geometric morphometric shape variables and discusses the advantages and limitations of the use of such data in studies of phylogeny. A method for fitting morphometric data to a phylogeny (i.e., estimating ancestral states of the shape variables) is presented using the squared-change parsimony criterion for estimation. These results are then...
متن کاملForm, function, and geometric morphometrics.
Geometric morphometrics (GM) has increasingly become an important tool in assessing and studying shape variation in a wide variety of taxa. While the GM toolkit has unparalleled power to quantify shape, its use in studies of functional morphology have been questioned. Here, we assess the state of the field of GM and provide an overview of the techniques available to assess shape, including aspe...
متن کاملGeometric morphometrics simplified
Although the theory andmethods of the relatively new field of geometric morphometrics are becoming well developed (for an overview, see [1]), it has not yet been applied as widely as it could be, owing to the lack of easily accessible introductory guides. This primer, by Miriam Zelditch and colleagues, should make the field more accessible because the new methods described here are relatively s...
