Evaluating the use of taxonomy in the IUCN Red List

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Austrocedrus from the Late Cretaceous of Antarctica and its implications for the early evolution of southern cypresses (Callitroideae, Cupressaceae)

open access: yesAmerican Journal of Botany, Volume 113, Issue 9, September 2026.
Abstract Premise The modern distribution of the southern cypresses, Callitroideae (Cupressaceae), reflects a classic Gondwanan distribution. The initial diversification of Callitroideae is estimated to have occurred during the Cretaceous, yet fossils from this period are rare, hampering our understanding of its early evolutionary history.

Spatial and Seasonal Analysis of Phyllosphere Bacterial Communities of the Epiphytic Gymnosperm Zamia pseudoparasitica

open access: yesApplied Biosciences
Phyllosphere microbial communities influence the growth and productivity of plants, particularly in epiphytic plants, which are disconnected from nutrients available in the soil. We characterized the phyllosphere of 30 individuals of the epiphytic cycad,

Distinct root‐associated fungal communities may account for the persistence of Podocarpus conifers in tropical forest

open access: yesEcology, Volume 107, Issue 9, September 2026.
Abstract Podocarps (Podocarpaceae) are one of the few lineages of conifers found in closed canopy tropical forests. They typically have highly restricted distributions that are associated with nutrient‐poor sites. Unlike other tree species, the presence of distinct nodule‐like structures allows their roots to be easily distinguished from those of co ...

Insights into the canopy of the iconic Lepidodendron aculeatum, based on new articulated fossils from the Bashkirian (Pennsylvanian) of Hagen‐Vorhalle, Germany

open access: yesPapers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract Lepidodendron aculeatum is an arborescent lycopod that populated the vast coal swamps in north‐western and central Europe during the late Carboniferous (Pennsylvanian) from the Bashkirian onwards, dominating the lush vegetation of tropical wetlands.

Cycads: Their evolution, toxins, herbivores and insect pollinators

open access: yes, 2002
Palaeobiological evidence indicates that gymnosperms were wind-pollinated and that insect pollination began in angiosperms in the Lower Cretaceous (ca. 135 mya) leading to close associations between higher plants and their pollinators. Cycads, which were

Fossil wood reveals climate stress and fungal decomposition in Late Triassic (Norian) forests in central Europe

open access: yesPapers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract Late Triassic forests in Central Europe developed under a seasonal sub‐tropical climate while the supercontinent Pangea was breaking up. Although permineralized fossil wood from this interval is abundant, its palaeoclimatic and palaeoecological significance has so far remained largely unexplored.
