Data from: Selective bird predation on the peppered moth: the last experiment of Michael Majerus

Laurence M. Cook, Bruce S. Grant, Ilik J. Saccheri, James Mallet, J. Mallet, L. M. Cook & I. J. Saccheri
Colour variation in the peppered moth Biston betularia was long accepted to be under strong natural selection. Melanics were believed to be fitter than pale morphs because of lower predation at daytime resting sites on dark, sooty bark. Melanics became common during the industrial revolution, but since 1970 there has been a rapid reversal, assumed to have been caused by predators selecting against melanics resting on today's less sooty bark. Recently, these classical explanations of...

Data from: Testing and quantifying phylogenetic signals and homoplasy in morphometric data

Christian Peter Klingenberg, Nelly A. Gidaszewski, Christian Peter Klingenberg & Nelly A. Gidaszewski
The relationship between morphometrics and phylogenetic analysis has long been controversial. Here we propose an approach that is based on mapping morphometric traits onto phylogenies derived from other data and thus avoids the pitfalls encountered by previous studies. This method treats shape as a single, multidimensional character. We propose a test for the presence of a phylogenetic signal in morphometric data, which simulates the null hypothesis of the complete absence of phylogenetic structure by permutation...

Data from: Change and stability in a steep morph-frequency cline in the snail Cepaea nemoralis (L.) over 43 years.

Robert A. D. Cameron, Laurence M. Cook & Jeremy J. D. Greenwood
Populations of the polymorphic land snail Cepaea nemoralis (L.) from Deepdale, Derbyshire, UK, sampled in 1965-67, showed a pattern of area effects, with steep clines among groups of populations differing in shell colour and banding morph frequencies. In 2010 most of these populations were resampled. In particular a continuous transect made in 1967 of 42 18.34m x 18.34m quadrats across a steep cline in several morph frequencies was completely resampled. In the dale as a...

Data from: Locomotory abilities and habitat of the Cretaceous bird Gansus yumenensis inferred from limb length proportions

Robert L. Nudds, Jessie Atterholt, Xia Wang, H. L. You, Gareth J. Dyke, J. Atterholt, R. L. Nudds, X. Wang & H.-L. You
The relative length proportions of the three bony elements of the pelvic (femur, tibiotarsus and tarsometatarsus) and pectoral (humerus, ulna and manus) limbs of the early Cretaceous bird Gansus yumenensis, a well-represented basal ornithuromorph from China are investigated and compared to those of extant taxa. Ternary plots show that the pectoral limb length proportions of Gansus are most similar to Apodiformes (swifts and hummingbirds), which plot away from all other extant birds. In contrast, the...
