Evolution and modularity in the guenons (2008, methodology): “Analyses were performed using geometric morphometrics (Bookstein, 1991; Dryden & Mardia, 1998; Zelditch et al., 2004) in the following computer programs: Morpheus (Slice, 1999), Morphologika, version 2.2 (O’Higgins & Jones, 2006), TPSSmall, version © 2008 The Linnean Society of London, Biological…”
geomorph: an r package for the collection and analysis of geometric morphometric shape data (2013, background): “In recent years, the quantitative study of anatomical form has matured into the ﬁeld of mor-phometrics: the study of shape variation and its covariation with other variables (Bookstein 1991; Rohlf & Marcus 1993; Adams, Rohlf & Slice 2004; Zelditch et al. 2004; Adams, Rohlf & Slice 2013).”

The long and winding road: identifying pig domestication through molar size and shape (2013, background): “In the superimposition, semi-landmarks are allowed to slide along the chord drawn between adjacent points to minimize the sum of Procrustes distances between each individual and the mean shape (Sampson et al., 1996; Perez et al., 2006; Zelditch et al., 2004; Sheets et al., 2004).”
Phylogenetic Principal Components Analysis and Geometric Morphometrics (2013, methodology): “…results from PCA and pPCAwere identical except for theML tree. pPCA scores can, therefore, be safely used as shape variables for most applications, just as partial warps scores (Bookstein, 1997a) can be used as shape variables even though they are similarly co-dependent (Zelditch et al., 2004).”
Cranial morphology and dietary habits of rodents (2009, methodology): “Relative warp analysis (RWA) was used to analyse the resultant data set; this method is similar to principal component analysis (PCA), but differs from PCA because it uses partial warp scores based on landmark data as variables and the components extracted are weighted by the bending energy matrix (”
Head shape allometry and proximate causes of head sexual dimorphism in Podarcis lizards: joining linear and geometric morphometrics (2007, methodology): “CS is the quantity standardized for in Procrustes Analysis and is uncorrelated to shape variables in the absence of allometry (Bookstein, 1991; Dryden & Mardia, 1998; Zelditch et al., 2004).”

Landmark based geometric morphometric analysis of wing shape in Sibiricobombus Vogt (Hymenoptera: Apidae: Bombus Latreille) (2007, methodology): “Because these measurements are highly correlated with size, much eff ort was spent for size correction (Zelditch et al. 2004).”

On the analysis of non‐linear allometries (2009, background): “Geometric morphometric techniques [see, for example, Zelditch et al. (2004) ] are a promising future avenue to follow, assuming that trait shapes as well as sizes change with morph in polyphenic species, but to date, tests of this have not been carried out.”
Systematics of the Platyrrhinus helleri species complex (Chiroptera: Phyllostomidae), with descriptions of two new species (2010, methodology): “Although PCA is a technique for simplifying descriptions of variation amongst individuals, CVA simplifies descriptions of differences amongst groups (Zelditch et al., 2004).”
Geometric morphometrics: recent applications to the study of evolution and development (2010, methodology): “…of quantitative biological shape analysis, while at the same time making it easier to collect and analyze data to answer questions about shape of the phenotype (Bookstein et al., 1985; Bookstein, 1991; Marcus et al., 1996; Dryden & Mardia, 1998; MacLeod & Forey, 2001; Zelditch et al., 2004).”
Geometric morphometrics in entomology: Basics and applications (2018, methodology): “The theory is rather involved for most researchers (and probably also for most entomologists!) who are not familiar with linear algebra; nevertheless, this approach definitely outweighs traditional morphometrics with reference to partitioning explicitly the geometric information into components of s”

I: an overview of phylogeographic patterns (2014, background): “, morphologically indistinguishable) species [105], while geometric morphometrics provides a powerful method for analyzing nuances of shape variation in a multivariate context [106] and thus can be used to confirm species delimitation from genetic coalescent results.”
