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).

Structural Variation of Plastomes Provides Key Insight Into the Deep Phylogeny of Ferns [PDF]
Frontiers in Plant Science, 2022 Structural variation of plastid genomes (plastomes), particularly large inversions and gene losses, can provide key evidence for the deep phylogeny of plants.

Evolution and expression of LEAFY genes in ferns and lycophytes [PDF]
EvoDevo, 2022 Background The LEAFY (LFY) transcription factors are present in algae and across land plants. The available expression and functional data of these genes in embryophytes suggest that LFY genes control a plethora of processes including the first zygotic ...

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 ...

Diversity and host plant utilization of leaf-mining beetles of Chrysomeloidea (Coleoptera) in Japan [PDF]
ZooKeysThe superfamily Chrysomeloidea (Cerambycidae + Chrysomelidae + Megalopodidae) encompasses a diverse phytophagous beetles, whose larvae exhibit internal or external feeding on leaves, wood, or roots of many plants.

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 ...

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.).
