Linnaeus's folly – phylogeny, evolution and classification ofSedum(Crassulaceae) and Crassulaceae subfamily Sempervivoideae

open access: yesTaxon, 2020
Sedum, containing approximately 470 species, is by far the largest genus of Crassulaceae. Three decades of molecular phylogenetic work have provided evidence for the non-monophyly of Sedum and many more of the 30 genera of Crassulaceae subfam ...

Patch Area and Soil Resource Availability Outweigh Heterogeneity in Shaping Karst Plant Diversity During Early Restoration

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
Patch area strongly influenced species and phylogenetic diversity in karst areas. Soil resource availability increased species and phylogenetic diversity. Soil nutrient heterogeneity shaped phylogenetic structure in early karst restoration. Patch shape and soil resource quantity outweighed heterogeneity in karst diversity.

Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi‐Species Ungulate Community

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We used DNA metabarcoding of 2,568 fecal samples to examine seasonal diets and resource partitioning among four deer species (moose, roe deer, red deer, fallow deer) across two Swedish landscapes. Deer consumed a wide range of plants, but diets were typically dominated by a few key taxa, with distinct dietary separation between moose and smaller deer ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

open access: yesPlant-Environment Interactions, Volume 6, Issue 5, October 2025.
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Unexpected spatial aggregation between two species of hummingbirds and their inconsistent spatial interactions with native and exotic plants in an urban ecological reserve

open access: yesIbis, Volume 167, Issue 4, Page 927-944, October 2025.
Hummingbirds play an important role as pollinators and are one of the primary examples of animal–plant coevolution. However, factors such as land‐use change, urbanization, exotic species introductions and the disappearance of native plants can negatively affect the persistence of hummingbird populations.

Neotypification of Sedum ochroleucum Chaix (Crassulaceae)

open access: yesNatural History Sciences, 2013
No original materials (herbarium specimens or drawings) connected with the protologue of Sedum ochroleucum Chaix (Crassulaceae) are to be found; thus the name has been neotypified, selecting a specimen collected by the author in the type locality at ...
