Diel net CO2 exchange of carnivorous Pinguicula is consistent with low‐level CAM photosynthesis

Plant Biology, EarlyView.
In carnivorous butterworts (Pinguicula), CO2 uptake occurs primarily in the light via C3 photosynthesis, yet low‐level CAM photosynthesis, including net CO2 dark fixation, significantly improves the carbon balance of plants, especially under water‐deficit conditions.

Transfer of Potentially Toxic Metal(loid)s From Ultramafic Soils in a Tri‐Trophic Food Chain Experiment

Ecological Research, Volume 41, Issue 5, September 2026.
Potentially toxic metal(loid)s (PTMs) bioaccumulated across a plant‐herbivore‐predator food chain. Irrespective of soil concentrations, female crickets actively selected PTM‐enriched leaves, while predatory mantids showed no developmental impairment. Trophic transfer of PTMs was rather influenced more by a function of intrinsic species traits than by ...

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Genomics is modifying our concepts of evolution in homosporous and heterosporous vascular plants

American Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Across the tree of life, and particularly within land plants, there is a wide diversity and disparity of genome structure. The most well‐studied are angiosperms, comprising mostly small and dynamic genomes, with a history of ancient whole genome duplications.

The Structure of Petioles in Pteris (Pteridaceae)

American Fern Journal, 2012
Abstract We studied the petiole structure of twelve American species of Pteris: P. ciliaris, P. cretica, P. deflexa, P. denticulata, P. ensiformis, P. exigua, P. inermis, P. multifida, P. mutilata, P. quadriaurita, P. tristicula and P. vittata, using both light and scanning electron microscopy. We found that petioles are characterized externally by the

Botanical inventory of the early book herbaria of Leonhard Rauwolf from southern France and northern Italy (1560–1563)

TAXON, Volume 75, Issue 4, August 2026.
Abstract Sixteenth‐century herbaria are the oldest plant collections that survive today and, as such, they provide valuable insights in past floras and historical botanical interactions. One of the most fascinating still extant 16th‐century herbaria is the four‐volume collection of the German physician, botanist and traveler Leonhard Rauwolf (1535 ...
