Duodichogamy and androdioecy in the Chinese Phyllanthaceae Bridelia tomentosa [PDF]

open access: yes, 2007
Flowering plants commonly separate male and female function in time, but rarely are the two stages synchronized within and among individuals. One such temporal mating system is duodichogamy in which each plant produces two batches of male flowers that ...

Digitised herbarium specimen data reveal a climate change‐related trend to an earlier, shorter Canadian Arctic flowering season, and phylogenetic signal in Arctic flowering times

open access: yesNew Phytologist, EarlyView.
Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.

Harnessing the benefits of herbarium specimen digitisation for inferring recent and ongoing plant extinctions

open access: yesNew Phytologist, EarlyView.
Summary Evidence for the ongoing biodiversity crisis rests on assessment of a small fraction of described species, with major knowledge gaps for most organisms, including plants. Here, we highlight how digitised herbarium specimens can be used to accelerate and improve estimates of recent and ongoing plant extinctions.

Pilliga Ghosts: The Novel Fungi of the Rivers, Creeks, Lakes, and Dams of the Narrabri Region, Australia

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Freshwater systems of the semi‐arid Narrabri region, Australia, are hotspots of novel fungal and eukaryote diversity, dominated by zoosporic fungi and unclassified lineages. ITS‑based DNA and water chemistry analyses across various water bodies revealed strong seasonal patterns, a scarcity of aquatic hyphomycetes that may reflect environmental ...

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Phylogenetic Diversity and Community Assembly of Vascular Plants Along Environmental Gradients in the Western Pamir–Alay: A Case Study From Surkhandarya Province, Southern Uzbekistan

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Using extensive field, herbarium, and database records, we examine patterns of species richness, phylogenetic diversity, and community assembly along elevational and climatic gradients in an understudied region of Central Asia. ABSTRACT Biodiversity plays a fundamental role in ecosystem structure, function, and stability, but its response to ...
