Divergence time and environmental similarity predict the strength of morphological convergence in stick and leaf insects Open
Independent evolution of similar traits in lineages inhabiting similar environments (convergent or repeated evolution) is often taken as evidence for adaptation by natural selection, and used to illustrate the predictability of evolution. …

Species delimitation 4.0: integrative taxonomy meets artificial intelligence Open
Although species are central units for biological research, recent findings in genomics are raising awareness that what we call species can be ill-founded entities due to solely morphology-based, regional species descriptions. This particu…

High disparity in repellent gland anatomy across major lineages of stick and leaf insects (Insecta: Phasmatodea) Open
Background Phasmatodea are well known for their ability to disguise themselves by mimicking twigs, leaves, or bark, and are therefore commonly referred to as stick and leaf insects. In addition to this and other defensive strategies, many …

A tree of leaves: Phylogeny and historical biogeography of the leaf insects (Phasmatodea: Phylliidae) Open
The insect order Phasmatodea is known for large slender insects masquerading as twigs or bark. In contrast to these so-called stick insects, the subordinated clade of leaf insects (Phylliidae) are dorso-ventrally flattened and therefore re…
