Dear morphometricians,
I like to draw your attention to some new papers (all are open access):
Grunstra NDS, Bartsch S, Le Maître A, Mitteroecker P (in press)
Detecting Phylogenetic Signal and Adaptation in Papionin Cranial Shape
by Decomposing Variation at Different Spatial Scales. /Systematic
Biology/ https://doi.org/10.1093/sysbio/syaa093
<https://urldefense.com/v3/__https://doi.org/10.1093/sysbio/syaa093__;!!Pp5KzSszWng!HjKPU_mdcaDohfMvfEeZJNSLJFtiyk_WXm3hJq8lz1Oz7-gR9urwGylYTLHOw979o501CdY$>
Here, we show how to decompose shape variation into shape components
that are likely to be functionally relevant and components that
capture "constructional details," such as the contributions of
different bones to overall shape. These latter components are largely
hidden from selection and thus tend to evolve more neutrally than
functional shape components. In a sample of papionin monkeys, we show
that these components of cranial shape indeed lead to a more reliable
phylogenetic reconstruction than overall cranial shape.

canalization, applied to human cranial form. /PLOS Computational
Biology/ 17(2): e1008381 https://doi.org/10.1371/journal.pcbi.1008381
<https://urldefense.com/v3/__https://doi.org/10.1371/journal.pcbi.1008381__;!!Pp5KzSszWng!HjKPU_mdcaDohfMvfEeZJNSLJFtiyk_WXm3hJq8lz1Oz7-gR9urwGylYTLHOw979nxWL4o0$>
In this paper we introduce a statistical model of canalized
development (sensu Waddington) and show how the strength of
canalization and the canalized variance can be estimated from
longitudinal data, even if the "target trajectories" of individual
development are unobserved. We extend this model to multivariate
measures and apply it to longitudinal geometric morphometric data on
human postnatal craniofacial size and shape as well as to the size of
the frontal sinuses.

Three-dimensional surface scanning methods in osteology: A
topographical and geometric morphometric comparison. /American Journal
of Physical Anthropology /https://doi.org/10.1002/ajpa.24204

This paper gives an overview and some empirical tests of 3D surface
scanning methods, especially photogrammetry, with applications to
human pelves.
All the best,
Philipp Mitteroecker
