For each species dataset, an alignment of 10 random leaf outlines including 100 pseudo-landmarks extracted from each species dataset. The tip of each leaf is marked with an orange circle, and the base of each leaf is marked with a blue circle. The vertical black line next to each leaf represents a 1 cm scale bar. For each species dataset, the total dataset mean leaf is represented by a black outline, which is superimposed onto the colored species mean leaf. Image credit: Hightower et al., 2026

Dorsal photograph of the red milkweed beetle traits we measured (green lines) including a dissected right mid-leg and mandibles: (traits from top to bottom of photograph) mandible size, antennae base, head width, thorax width, antennae tip, right elytra length, and right mid-leg length. We placed three landmarks (red points) and two semi-landmark curves (30 each) on the medial (point 2 to 3 highlighted in blue) and lateral (point 1 to 2 highlighted in orange) sides of the left mandible.

Molecular and morphological data support the synonymy of Muricanthus radix Gmelin, 1791 and Muricanthus ambiguus Reeve, 1845 (Gastropoda, Muricidae) The Muricanthus radix/ambiguus/nigritus complex includes species with a great diversity of shell shapes and shared habitats in various regions, which has raised questions and doubts about the current ...

For the first time, phylogenetic relationships between the sea snails Muricanthus nigritus, M. ambiguus and M. radix are established.

Effects of forest type (a–d), elevation (e–h) and lineage (a–h) on species diversity (expressed as Shannon index) and species' disparity (expressed by the Euclidean distance and body length) and general morphospace volume (expressed by the median centroid size). The plots show predictions from generalised linear mixed-effects models (a–d) and generalised additive models (e–h). Error bars (a–d) and shading (e–h) show 95% confidence intervals.
