Cytoskeleton, Volume 83, Issue 6, Page 394-406, June 2026.ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees
Ecology and Evolution, Volume 16, Issue 6, June 2026.Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

Ecology and Evolution, Volume 16, Issue 6, June 2026.Soil and precipitation can drive divergence in plant populations, yet less is known about the potential for synergistic effects between soil and precipitation on reproductive traits. We characterized variation in flowering phenology across soil boundaries and along a precipitation gradient and experimentally evaluated how water limitation affects ...

Ecology and Evolution, Volume 16, Issue 6, June 2026.Two Asian orchids, Arundina graminifolia and Spathoglottis plicata, are expanding into tropical regions worldwide, showing invasive behavior. In this study, we investigated the factors underlying their success. Both species—as all orchids—require fungal carbon to germinate, but S.

(A) Egg mass; (B) larva; (C) pupae; (D) adult (scale bar = 5.0 mm). ABSTRACT The ragweed leaf beetle Ophraella communa LeSage is an exotic species reported to have been introduced to Korea in 2002. It has spread and inhabits the entire Korean Peninsula using ragweed,

The seed bank created by the dung of large herbivores drives seed circulation in an alpine meadow
Ecosphere, Volume 17, Issue 6, June 2026.Abstract Seed circulation (i.e., sexual reproduction) is vital for the regeneration of aboveground grassland vegetation (AGV). It occurs in several steps: seed production (seed rain, SR), dispersal (endozoochory, i.e., dung seed bank, DSB), formation of the soil seed bank (SSB), germination, seedling growth, and establishment of adult plants.
