Aperture evolution in Nymphaeaceae: insights from a micromorphological and ultrastructural investigation

open access: yes, 2013
The evolution of the apertural type in the ANITA-grade family Nymphaeaceae, despite the importance of pollen characters for both palaeobotanical and neobotanical investigations, has not been yet totally understood.

Notes on the Embryology of the Nymphaeaceae [PDF]

open access: yesBotanical Gazette, 1909
1. Extra embryo sacs are frequently formed. 2. The cross-wall between the two daughter nuclei, which are formed by the first division of the endosperm nuleus, is usually present, although so delicate that it is very difficult to demonstrate. 3. The nucleus in the micropylar end of the sac forms the endosperm. 4.

Beetle Pollination in the Holoparasitic Lophophytum pyramidale (Balanophoraceae): A New Case of Brood‐Pollination Mutualism?

open access: yesJournal of Applied Entomology, Volume 149, Issue 10, Page 1542-1554, December 2025.
ABSTRACT Beetle pollination is considered an ancestral trait in angiosperms, retained in a few specialised families engaging in longstanding interactions with ancient groups of beetles. While beetles represent some of the earliest angiosperm pollinators, there is also increasing evidence that some beetle‐pollinated plants represent a derived condition.

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.

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 ...
