Community‐driven variations in snow algae color modulate snow albedo reduction

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1739-1752, February 2026.
Summary Snow algae blooms visibly alter snow color and surface energy balance, yet the biological basis of this variability remains unclear. We investigated how pigment composition and community structure shape the optical properties of snow algae blooms of distinct colors – red, orange, and green – co‐occurring within the same snowfield in Glacier ...

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 ...

Thylakoids reorganization enables driving photosynthesis under far‐red light in the microalga Nannochloropsis gaditana

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1785-1799, February 2026.
Summary Oxygenic photosynthesis is driven by visible light in most photosynthetic organisms, with exceptions in a few cyanobacteria and microalgae species, which can extend the light absorption to far‐red (FR) wavelengths, by synthesizing new pigments or shifting the antennae absorption range beyond 700 nm.

Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North
