Many biological structures lack easily definable landmarks, making it difficult to apply modern morphometric methods. Here we illustrate methods to study the mouse baculum (a bone in the penis), including dissection and microCT scanning, followed by computational methods to define semi-landmarks that are used to quantify size and shape variation.

In order to examine gene expression in the pupal wing tissue of Bicyclus anynana, we present an optimized protocol for in situ hybridizations using riboprobes. We also provide guidelines for the further optimization of this protocol for use in pupal wings of other Lepidopteran species.

This video demonstrates three types of morphometric analyses of the retina, which include measuring the inner nuclear layer thickness, quantifying the number of retinal ganglion cells (RGCs) and measuring the sizes of RGCs. The technique can offer a simple but scientific platform for morphometric analyses.

Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire An airfoil is a 2-dimensional wing section that represents critical wing performance characteristics. The pressure distribution and lift coefficient are important parameters that characterize the behavior of airfoils. The pressure distribution is directly related to the lift generated by airfoils. A Clark Y-14 airfoil, which is used in this...
FAQs
These measurements describe different aspects of wing form rather than treating size as a single trait. Length captures a linear dimension, area represents overall surface extent, and aspect ratio expresses proportions between dimensions. Examining them together helps researchers distinguish differences in size from differences in shape, supporting comparisons of organisms whose wings may vary in multiple, biologically meaningful ways.
Traditional morphometrics analyzes measurements such as wing length, area, and aspect ratio, whereas geometric morphometrics uses landmark coordinates to characterize shape. The two approaches therefore represent form differently: one emphasizes selected numerical dimensions, while the other evaluates spatial relationships among points. Choosing between them depends on whether the study focuses on straightforward proportions or broader patterns of shape variation.
Standardization makes measurements more consistent across the groups being studied. With a common approach, researchers can compare species, populations, sexes, developmental stages, or individuals without changing the basis of measurement from one group to another. This improves the interpretation of observed variation and helps connect differences in wing form with biological history, performance, or environmental adaptation.
Researchers may record direct measurements from wings or capture the coordinates of defined landmarks. The resulting data can be used to calculate or analyze variables including length, area, aspect ratio, and overall shape. This combination allows a study to examine both readily measured dimensions and more detailed spatial patterns, depending on the biological question and morphometric method selected.
Wing form provides measurable characters for comparing organisms and identifying patterns among species or populations. Taxonomic studies can use differences in size, proportions, or shape as part of biological comparisons, while evolutionary research can examine how those traits vary across groups and relate to biological history. The approach therefore turns visible wing differences into standardized data for comparative analysis.
Patterns in wing size and shape can be evaluated alongside functions such as flight and dispersal. Researchers can compare these traits among organisms or populations to investigate whether particular forms are associated with differences in performance or environmental conditions. Such analyses do not rely on appearance alone; they use quantitative measurements to connect wing form with biological function and adaptation.
A study can organize measurements or landmark coordinates by sex, developmental stage, population, species, or individual, then examine the resulting differences in size, proportions, and shape. These comparisons reveal whether wing form varies within or among biological groups. The same framework also supports investigations of developmental stability by providing consistent, measurable traits for analysis.
