The Franks Model CO2 Proxy: Do Assimilation Rate Values or Isotopic Corrections Optimize CO2 Reconstruction Accuracy?

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Paleo‐CO2 proxies are crucial for reconstructing past atmospheric CO2 variations and understanding their impact on Earth's climate, especially in light of anthropogenic climate change. The mechanistic leaf gas exchange model of Franks et al.

Enhanced Reconstruction of Holocene Bryophytes From Sedimentary Ancient DNA Using Bryophyte‐Targeted Primers

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Bryophyte‐targeted primers captured a longer DNA fragment, moving beyond the indirect “bycatch” approach using vascular plant primers. This improved detection and recovered greater bryophyte diversity, with substantial overlap with taxa obtained through bycatch.

The role of Alpine botanical gardens in integrating germplasm bank collections and mission

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 680-692, March 2026.
This study underscores the vital role of Alpine botanical gardens (ABGs) in safeguarding Europe's alpine biodiversity amid climate change and habitat loss. By acting as living laboratories and reservoirs of plant genetic resources, ABGs bridge ex situ and in situ conservation, supporting ecosystem resilience and informing restoration strategies.

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of
