Fine‐tuning the buzz: comparing visitation frequency and pollination effectiveness in plant–pollinator networks

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2140-2152, February 2026.
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.

Temperature‐dependent pollinator‐mediated selection on floral thermoregulation

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1716-1726, February 2026.
Summary The thermal environment is one of the most pervasive agents of selection. Most plants cannot choose their microclimate, so understanding how they cope with thermal variability is of critical concern. Several floral traits can modify the floral thermal microenvironment, which may alleviate negative impacts of thermal extremes on gametophytes and

Morphology of Metzgeria conjugata Lindb. (Metzgeriales, Hepaticopsida) [PDF]

open access: yes, 1992
Scanning electron microscopy and light microscopy were used to elucidate the morphology of Metzgeria conjutata Lindb. and confirm the presence of 2 rows of epidermal cells on the dorsal surface, (21-3) rows on the ventral surface, midrib with cells in (3-

Contemporary hybridization among Arabis floodplain species creates opportunities for adaptation

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1542-1557, February 2026.
Summary Hybridization between closely related species is increasingly recognized as a major source of biodiversity. Yet, whether it can create advantageous trait combinations while purging harmful alleles remains unknown. To address this question, we studied Arabis nemorensis and Arabis sagittata, two endangered species that currently hybridize in a ...

MAA3 (MAGATAMA3) Helicase Gene is Required for Female Gametophyte Development and Pollen Tube Guidance in Arabidopsis thaliana [PDF]

open access: yes, 2017
The female gametophyte plays a central role in the sexual reproduction of angiosperms. We previously isolated the maa3 (magatama3) mutant of Arabidopsis thaliana, defective in development of the female gametophyte, micropylar pollen tube guidance, and ...
