Starving for oxygen: the effect of hypoxia on seed germination and secondary dormancy induction in Mediterranean temporary ponds plant species

Plant Biology, Volume 28, Issue 2, Page 432-440, March 2026.
This study examined the germination adaptations to hypoxia of species along a plant zonation in Mediterranean temporary ponds, highlighting the key traits that support their survival and regeneration. Abstract Mediterranean temporary ponds (MTPs) are dynamic habitats where low levels of dissolved oxygen can significantly impact plant life.

Phytoliths of pteridophytes

South African Journal of Botany, 2011
AbstractStudy of phytoliths of pteridophytes is an emerging area of research. Literature on this aspect is limited but increasing. Some recent findings have shown that phytoliths may have systematic and phylogenetic utility in pteridophytes. Phytoliths are functionally significant for the development and survival of pteridophytes. Experiments with some

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

The Anatomical Record, Volume 309, Issue 1, Page 5-32, January 2026.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated
