Lineage-specific vs. universal: A comparison of the Compositae1061 and Angiosperms353 enrichment panels in the sunflower family. [PDF]

open access: yesAppl Plant Sci, 2021
Premise Phylogenetic studies in the Compositae are challenging due to the sheer size of the family and the challenges they pose for molecular tools, ranging from the genomic impact of polyploid events to their very conserved plastid genomes. The search for better molecular tools for phylogenetic studies led to the development of the family‐specific ...

Decay stages of Jurassic wood debris from Scotland: evidence for the coevolution of fungal rot, arthropods and the nurse log strategy. [PDF]

open access: yesNew Phytol
Summary A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for young tree species, leading to this type of seedbed being termed ‘nurse logs’.

A phylogenomic approach to disentangling the evolution of the large and diverse daisy tribe Anthemideae (Asteraceae)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 2, Page 282-306, March 2025.
The daisy tribe (Anthemideae) is one of the most diverse within the Asteraceae family, which is the largest or second largest of all angiosperms. We analyzed the intricate evolutionary relationships within this tribe using a targeted high‐throughput sequencing phylogenomic approach.

Middle Triassic dipterid ferns from west-central Argentina and their relationship to palaeoclimatic changes [PDF]

open access: yesActa Palaeontologica Polonica, 2018
Dipterid ferns possess robust fossil record from Mesozoic times on, and they are considered to be a reliable indicator of warm to subtropical humid or seasonal paleoclimatic conditions. In this contribution, we revised and described new samples of fossil
