Nordic Journal of Botany, Volume 2026, Issue 10, October 2026.Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Molecular Ecology, Volume 35, Issue 19, October 2026.ABSTRACT As human activity accelerates the spread of pathogens and other invasive species, reconstructing the cryptic early dynamics of undetected invasions has become a central challenge in disease ecology and invasion biology. Here, we leverage museum specimens to reconstruct the invasion of Batrachochytrium dendrobatidis (Bd), a fungal panzootic ...

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes
New Phytologist, Volume 252, Issue 1, Page 54-68, October 2026.Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

The genus Arthrocardia (Corallinales, Rhodophyta) in New Zealand: Description of three new species
Phycological Research, Volume 74, Issue 4, Page 333-342, October 2026.SUMMARY Three new species of the coralline algal genus Arthrocardia (Corallinophycidae, Rhodophyta) are described from New Zealand: A. meridionalis, A. perplexa, and A. robusta. These species are difficult to distinguish based on morphoanatomical characters alone and require molecular sequence data for reliable identification.
