High Species Diversity in Fleshy-Fruited Tropical Understory Plants [PDF]

open access: yes, 2001
Key innovations may increase the number of taxa in a clade that possesses the proposed innovation in comparison to its sister group that lacks the trait through either increased speciation or reduced extinction rates.

Omnivorous Diets of Sympatric Duck Species in a Subtropical East Asia Wetland Unveiled by Multi‐Marker DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
The East Asian–Australasian Flyway (EAAF) is experiencing significant declines in migratory waterbird populations. Understanding the foraging ecology of waterbird species, particularly ducks, is crucial for monitoring and protecting their food sources and wetland habitats.

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

open access: yes, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid‐independent manner

open access: yesThe Plant Journal, Volume 123, Issue 5, September 2025.
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...

A single polyploidization event at the origin of the tetraploid genome of Coffea arabica is responsible for the extremely low genetic variation in wild and cultivated germplasm [PDF]

open access: yes, 2020
The genome of the allotetraploid species Coffea arabica L. was sequenced to assemble independently the two component subgenomes (putatively deriving from C. canephora and C.

Conservation Implications for the Iberian Narrow Endemic Androsace cantabrica (Primulaceae) Using Population Genomics With Target Capture Sequence Data

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
This study uses Angiosperms353 target capture sequencing to resolve the taxonomic status and conservation needs of Androsace cantabrica, a rare alpine plant endemic to northern Spain. Phylogenomic analyses confirm its distinctiveness from related species, and population genomic data reveal shallow genetic structure and moderate diversity, supporting ...
