New canopy legume species highlight liana gap sampling across Amazonian and Atlantic rain forests

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Lianas are a key component of the Neotropical flora, accounting for 10% of angiosperm richness and playing important ecological roles. However, the canopy preference of some species often leads to their underrepresentation in herbarium collections, thereby exacerbating Linnaean, Darwinian, and Wallacean shortfalls. The papilionoid legume genus

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Cognitive Linguistics and the Poetics of Time: Is 9/11 a Conceptual Metaphor, a Conceptual Metonymy or Both?

open access: yesMiscelánea: A Journal of English and American Studies, 2010
Time has always hard-pressed the human symbolic capacity for language to an extent that few other concepts have. Equally, it has helped to linguistically shape human narrative imagination in a creative interaction with space that no other concept has ...

open access: yesFossil Record
Azzabaremys moragjonesi, from the Paleocene of Mali, is a member of Nigeremydini. This is a clade of bothremydid pleurodiran turtles that includes large putatively marine forms which inhabited the African Trans-Saharian Seaway from the Maastrichtian to ...

Edaphic isolation as a driver of divergence in a new Amazonian species of Diclinanona (Annonaceae)

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract For many years a mysterious collection made during an expedition to Venezuelan Amazonia in 1992 was in a folder at the former Utrecht Herbarium as “unidentified Annonaceae”. Several different genera were suggested for identification but since flowers were lacking it was unclear where this taxon should be placed. One of the suggestions based on

From living to fossil: ancestral state reconstruction of leaf architecture in extant Lauraceae and its relevance for the fossil record

open access: yesPalaeontology, Volume 69, Issue 3, 2026.
Abstract Lauraceae are a tropical–subtropical angiosperm family that exhibit significant diversity and a rich fossil record, primarily of leaves found worldwide from the Cretaceous to the present. However, the taxonomic placement of many fossil leaves remains uncertain because of morphological convergence and limited variation in leaf characters among ...
