Widely acclaimed but poorly named: Phylogeny and systematics of the African daisy genus Dimorphotheca (Asteraceae, Calenduleae)

TAXON, Volume 74, Issue 1, Page 133-154, February 2025.
Abstract Phylogenetic relationships in the South African daisy genus Dimorphotheca have long been uncertain, with the taxonomy of the genus relying on a few morphological traits, most prominently capitulum sexual system (e.g., cypsela type) and ray colour, which may not be evolutionarily conserved.

Fire drives major Holocene vegetation shifts between subtropical and Mediterranean‐type ecosystems: a case study from a biodiversity hotspot in South Africa

Ecography, Volume 2024, Issue 12, December 2024.
Fire plays a pivotal role in driving ecological shifts between Mediterranean‐type vegetation and subtropical ecosystems in South Africa. This study investigates long‐term environmental dynamics and ecological regime changes at the Mediterranean‐type vegetation /subtropical boundary using a 6000‐year palaeoecological sequence from the Baviaanskloof – a ...

Phylogenomics and phylogeographic model testing using convolutional neural networks reveal a history of recent admixture in the Canarian Kleinia neriifolia

Molecular Ecology, Volume 33, Issue 21, November 2024.
Abstract Multiple‐island endemics (MIE) are considered ideal natural subjects to study patterns of island colonization that involve recent population‐level genetic processes. Kleinia neriifolia is a Canarian MIE widespread across the archipelago, which exhibits a close phylogenetic relationship with species in northwest Africa and at the other side of ...

Seeing double: two different homospermidine oxidases are involved in pyrrolizidine alkaloid biosynthesis in different organs of comfrey (Symphytum officinale)

The Plant Journal, Volume 119, Issue 3, Page 1272-1288, August 2024.
SUMMARY Pyrrolizidine alkaloids (PAs) are toxic specialized metabolites produced in several plant species and frequently contaminate herbal teas or livestock feed. In comfrey (Symphytum officinale, Boraginaceae), they are produced in two different organs of the plant, the root and young leaves. In this study, we demonstrate that homospermidine oxidase (
