#OpenAccess Clonal Expansion Accounts for Most Post-Disturbance Proliferation of a Dominant Temperate Liana, Wisteria floribunda, Across a Fragmented Forest Landscape Hideki Mori, Takashi Kamijo ▶️ doi.org/10.1111/1442... anthropogenic disturbance/ clonal reproduction/ fragmentation/ woody vines

Graphical abstract: Across all sampled ramets in a fragmented forest landscape, 83% were clonal, indicating that clonal expansion accounted for most of the present population structure of Wisteria floribunda. Compared with a continuous old-growth forest, the fragmented forest showed substantially greater clonal dominance and spatial coverage by genets.

◤小さな花の雄しべにも役割分担！◢ ノボタン科のハシカンボクは2種類の雄しべをもち、一方はハナバチへの「ごほうび」、もう一方は受粉を担います。花粉を運びつつも、過剰に持ち去ってしまうハナバチに対する、植物の巧みな戦略を明らかにした研究です。 本研究は、2025年度（第57回）種生物学シンポジウムで「PSB推しポスター」に選ばれ、Plant Species Biologyへの投稿に招待された研究に基づいています。 x.gd/ancmj2 受賞ならびに出版おめでとうございます！ 🐝▶️ doi.org/10.1111/1442... 📸 Tetsuya Fukano

<NOTES & INSIGHTS> Seed Floras in Seabird Nests and the Possibility of Adhesion to Seabird Feathers via Their Nests Kanon Mizukoshi, Kazuto Kawakami, Takashi Kamijo ▶️ doi.org/10.1111/1442... #OpenAccess #ornithology epizoochory/ long-distance dispersal (LDD)/ oceanic islands

Graphical abstract: Nests are important links between seabirds and plants, and are thought to initiate epizoochory of seabirds. 24 seed species were found in pelagic seabird nests, and 16 species of them had the potential to adhere to seabirds. Our finding indicates an overlooked pathway for the long distance dispersal of plants; epizoochory mediated by nests.

Flowcytometric and Allozymic Studies on the Korean Dandelion (Taraxacum, Asteraceae), With Special Reference to the Hybrid Origin of Taraxacum coreanum Nakai Tatsuyoshi Morita et al ▶️ doi.org/10.1111/1442... #OpenAccess allotetraploid/ facultative agamospermy

Graphical abstract: We found that the Korean tetraploid Taraxacum coreanum (Co) shows fixed heterozygosity at two dimeric enzyme loci, sod-1 (aaab) and mdh-1 (bddd). Allele-specific comparisons indicate that sod-1 ‘a’ and mdh-1 ‘d’ are characteristic of the triploid T. mongolicum (Mo) whereas the ‘b’ alleles at both loci match Korean diploids (e.g., T. hallaisanense, Ha). Together, these results support a hybrid origin for T. coreanum between T. mongolicum and Korean diploid species, corroborated by flow cytometry.

#OpenAccess Effect of Seed Position on Parental Plant of Kroenleinia grusonii (Hildm.) Lodé. and Echinocactus platyacanthus Link & Otto on #Seed Germination at High Temperatures Carlos A Zúñiga, Cecilia B Peña-Valdivia et al ▶️ doi.org/10.1111/1442... Cactaceae/ scarification

Graphical abstract: • Kroenleinia grusonii and Echinocactus platyacanthus are native and endemic to Mexico, both have ecological and economic importance and are endangered species. • The position in which seeds develop on the parental plant can have effects on physical and physiological characteristics. • Seed position on parental plant of Kroenleinia spp. and Echinocactus spp. may affect its physical or physiological quality.

#OpenAccess The Function of the Partially-Opened Spathe of Pinellia pedatisecta (Araceae) as a Pitfall Pollinator Trap Kohei Yanagisawa, Tetsuya K Matsumoto ▶️ doi.org/10.1111/1442... aroid/ deceptive #pollination system/ introduced species/ #pollinator shift/ trap flower

Graphical abstract: Pinellia pedatisecta has a simplified inflorescence structure, compared to its congeners with highly specialized trap pollination systems. However, our study suggests that P. pedatisecta also captures and releases pollinating insects by the spathe movement during flowering season.

We’ve just published ‘Notes and Insights’ on the pollination ecology of Achyranthesis bidentata. This is a part of my undergrad work a long long time ago. I thank Plant Species Biology @plantspeciesbio.bsky.social for its openness to such an understudied plant species. doi.org/10.1111/1442...

<NOTES & INSIGHTS> #OpenAccess Recurrent Visitation by Lycaenid Butterflies and Honeybees to the Same Individuals of Achyranthes bidentata (Amaranthaceae) Yasuhiro Sato @yassato.bsky.social , Takayoshi Nishida 👉 doi.org/10.1111/1442... bee/ butterfly/ generalist/ #pollination

Graphical abstract: The common perennial weed Achyranthes bidentata (Amaranthaceae) produces many flowers to attract diverse insect pollinators. The authors here found that lycaenid butterflies made long-distance visits between individual plants, whereas honeybees were inclined to visit multiple flowers within an individual plant. These findings highlight potential agents of pollinator-mediated plant–plant interactions.

#OpenAccess Phylogenetic and Population Genetic Analysis Decipher the Taxonomic Consistency on Cryptic Betula costata Trautv. (Betulaceae) Populations in Japan and the Process on Its Divergence and Isolation Takaki Aihara et al doi.org/10.1111/1442... leaf morphology

Graphical abstract: Betula costata, a deciduous broad-leaved tree habits in the cool-cold temperate forests in East Asia, is an ideal species for studying the persistence of relict plants. Although cryptic populations of this species have been reported in central Japan in recent years, species delineation of them using molecular evidence has not been undertaken. This study is the first to estimate the phylogenetic position of putative B. costata populations in Japan and supported the classification of them as B. costata. Our analysis also suggests that B. costata in Japan diverged from continental populations and has persisted in isolated enclaves with benign environmental conditions since the Last Glacial Maximum.

#OpenAccess Forest Structure and Maintenance Mechanisms of Montane Riparian Forests Under Extreme Snowfall in the Cool‐Temperate Zone of Western Fukushima, Japan Yosuke Nakano et al doi.org/10.1111/1442... creeping/ dwarf montane riparian forest/ layering/ sprouting

Graphical abstract: In extreme heavy snowfall environments (maximum snow depth of 5 m), dominant species such as Pterocarya rhoifolia and Aesculus turbinata exhibited different survival strategies—sprouting, dwarfing, and layering—compared to their tall forms in heavy snowfall areas (maximum 2 m). Additionally, Acer nipponicum, common in snowy regions, was also dominant, suggesting that montane riparian forests under extreme snow accumulation are maintained by tree species adapted to such conditions.
