Seeing distinct groups where there are none: spurious patterns from between-group PCA
Using sampling experiments, we found that, when there are fewer groups than variables,
between-groups PCA (bgPCA) may suggest surprisingly distinct differences among groups …

Genomic architecture of ecologically divergent body shape in a pair of sympatric crater lake cichlid fishes
Determining the genetic bases of adaptations and their roles in speciation is a prominent
issue in evolutionary biology. Cichlid fish species flocks are a prime example of recent rapid …

Sharing is caring? Measurement error and the issues arising from combining 3D morphometric datasets
Geometric morphometrics is routinely used in ecology and evolution and morphometric
datasets are increasingly shared among researchers, allowing for more comprehensive …

Bat species comparisons based on external morphology: a test of traditional versus geometric morphometric approaches
External morphology is commonly used to identify bats as well as to investigate flight and
foraging behavior, typically relying on simple length and area measures or ratios. However …

Genetic linkage of distinct adaptive traits in sympatrically speciating crater lake cichlid fish
Our understanding of how biological diversity arises is limited, especially in the case of
speciation in the face of gene flow. Here we investigate the genomic basis of adaptive traits …

Ecomorphological adaptation in three mudskippers (Teleostei: Gobioidei: Gobiidae) from the Persian Gulf and the Gulf of Oman
We hypothesise that the body shapes of three mudskipper species (Boleophthalmus
dussumieri, Periophthalmus waltoni, and Scartelaos tenuis) are ecomorphological …

Phylogeographical relationships of Sicilian brown trout and the effects of genetic introgression on morphospace occupation
Genetic introgression of aquaculture stocks in local forms is well documented in many fish
species but their evolutionary consequences for the local populations have not been …

Tissue preservation can affect geometric morphometric analyses: a case study using fish body shape
In geometric morphometrics, the extent of variation attributable to non-biological causes (ie
measurement error) is sometimes overlooked. The effects of this variation on downstream …

Towards understanding the genetic basis of mouth asymmetry in the scale‐eating cichlid Perissodus microlepis
How polymorphisms consisting in left–right asymmetries are produced and maintained in
natural populations is a tantalizing question, which remains largely unanswered. The scale …
