Environmental metagenetics unveil novel plant-pollinator interactions. [PDF]
Ecol Evol, 2023 We used pollen metabarcoding to investigate if honey bees interact with and disperse cells from non‐flowering plants. We discovered that honey bees may serve as dispersal agents for an array of sporophytes (Anchistea, Claytosmunda, Dryopteris, Osmunda, Osmundastrum, Equisetum) and bryophytes (Funaria, Orthotrichum, Sphagnum, Ulota).

Herbivory Dominates the Spring Diet of American Black Bears (<i>Ursus americanus</i>) in a Wood Bison (<i>Bison bison athabascae</i>) Neonatal Range, Suggesting Minimal Bison Consumption. [PDF]
Ecol EvolIn this study, we used scat analysis and DNA metabarcoding to analyze the spring diet of black bears in the neonatal range of a small, threatened wood bison herd in northeast Alberta to assess predation risk of neonate bison. Our results suggest that consumption rates of bison are low and that predation risk to neonate wood bison, during the RLBH's ...

Global Diversification Rates of Ferns Across Spatial and Climatic Gradients. [PDF]
Adv Sci (Weinh)Diversification rates of fern genera across the phylogeny. Abstract Geographic patterns of diversity in any group of plants are the result of the interplay of environmental conditions and the evolutionary dynamics of the respective plant group. Here, the geographic distribution of current mean diversification rates (MDR) is explored at the genus level ...

Deductive automated pollen classification in environmental samples via exploratory deep learning and imaging flow cytometry. [PDF]
New Phytol, 2023 Summary Pollen and tracheophyte spores are ubiquitous environmental indicators at local and global scales. Palynology is typically performed manually by microscopic analysis; a specialised and time‐consuming task limited in taxonomical precision and sampling frequency, therefore restricting data quality used to inform climate change and pollen ...

Non‐seed plants are emerging gene sources for agriculture and insect control proteins
The Plant Journal, Volume 116, Issue 1, Page 23-37, October 2023., 2023 SUMMARY The non‐seed plants (e.g., charophyte algae, bryophytes, and ferns) have multiple human uses, but their contributions to agriculture and research have lagged behind seed plants. While sharing broadly conserved biology with seed plants and the major crops, non‐seed plants sometimes possess alternative molecular and physiological adaptations ...

Origin of Equisetum: Evolution of horsetails (Equisetales) within the major euphyllophyte clade Sphenopsida [PDF]
American Journal of Botany, 2018 Premise of the StudyEquisetum is the sole living representative of Sphenopsida, a clade with impressive species richness, a long fossil history dating back to the Devonian, and obscure relationships with other living pteridophytes. Based on molecular data, the crown group age of Equisetum is mid‐Paleogene, although fossils with possible crown ...

Papers in Palaeontology, Volume 9, Issue 5, September/October 2023., 2023 Abstract The first anatomically preserved wood specimens of an upland Carboniferous flora from the Iberian Peninsula are reported from the Erillcastell Basin (Eastern Pyrenees, Catalonia, Spain). Two taxa are described, a calamitacean Equisetales (Arthropitys sp.) and a Cordaitales (Dadoxylon sp.).

Toward freshwater plant diversity surveys with eDNA barcoding and metabarcoding
Environmental DNA, Volume 5, Issue 4, Page 648-670, July 2023., 2023 In this manuscript we present a synthesis of the 22 studies working on eDNA barcoding and metabarcoding approaches for monitoring freshwater plants in lentic, lotic and wetland habitats. We also examine the specific primers, barcodes and reference databases required for succesful plant eDNA surveys.

Palaeontology, Volume 66, Issue 3, May/June 2023., 2023 Abstract Wetlands are important to continental evolution, providing both arenas and refugia for emerging and declining biotas. This significance and the high preservation potential make the resulting fossiliferous deposits essential for our understanding of past and future biodiversity.

Fern cell walls and the evolution of arabinogalactan proteins in streptophytes
The Plant Journal, Volume 114, Issue 4, Page 875-894, May 2023., 2023 Significance Statement Ferns are the sister lineage of seed plants and key to understanding plant evolution. To understand ferns' unique cell walls, we analyzed arabinogalactan proteins (AGPs) from the fern genera Azolla, Salvinia, and Ceratopteris. Comparison of AGP structures throughout the streptophyte lineage reveals special features in relation to
