Directional seed and pollen dispersal and their separate effects on anisotropy of fine‐scale spatial genetic structure among seedlings in a dioecious, wind‐pollinated, and wind‐dispersed tree species, Cercidiphyllum japonicum

open access: yesEcology and Evolution, 2021
Prevailing directions of seed and pollen dispersal may induce anisotropy of the fine‐scale spatial genetic structure (FSGS), particularly in wind‐dispersed and wind‐pollinated species.

Are plant species able to keep pace with the rapidly changing climate? [PDF]

open access: yesPLoS ONE, 2013
Future climate change is predicted to advance faster than the postglacial warming. Migration may therefore become a key driver for future development of biodiversity and ecosystem functioning.

From flower to fruit: The origin of the trilocular ovary and fruit development in Phragmipedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae: Cypripedioideae). [PDF]

open access: yesPlant Biol (Stuttg)
Phragmipedium longifolium has a trilocular ovary with a post‐genital septum, and during fruit development, lignification plays a crucial role in facilitating dehiscence and seed dispersal. Abstract While carpels in Orchidaceae are predominantly unilocular, trilocular carpels can also occur, mainly in branches separated during the early diversification ...

Trees in trees a report from remote Australia

open access: yesPlant Signaling & Behavior, 2023
Anemochory or Ornithochory does not adequately explain the amount, size or distribution of woody epiphytes here in outback NSW Australia. In a semi-arid ecosystem, epiphytes should be short-lived and randomly dispersed not clustered around old Aboriginal
