Sedimentary Metagenomics Reveal Avian Community Transitions From the Last Glacial Maximum to the Holocene

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We used sedimentary ancient DNA shotgun metagenomics to reconstruct past bird communities in northern high‐latitude environments. By using long time series and data collected across a large environmental gradient, we contributed in a unique and explorative way to the understanding of palaeoecological dynamics between birds and their habitat on the ...

Diterpenoid Diversity across Land Plants

open access: yesHelvetica Chimica Acta, Volume 109, Issue 4, April 2026.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

Convergence and parallelism in the evolution of plant metabolism

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

CLE peptides in plant‐biotic interactions

open access: yesNew Phytologist, Volume 250, Issue 2, Page 805-811, April 2026.
Summary Plant‐biotic interactions are driven by the exchange of molecules. Small peptide hormones like CLAVATA3/EMBRYO SURROUNDING REGION (CLE) peptides play central regulatory roles in these interactions. CLEs determine the extent of symbiotic interaction to balance costs and benefits for the host.

Climate Change Impacts the Structure and Nitrogen‐Fixing Activities of Subarctic Feather Moss Microbiomes Across a Precipitation Gradient

open access: yesGlobal Change Biology, Volume 32, Issue 2, February 2026.
Associations between mosses and cyanobacteria are crucial sources of new nitrogen in arctic and subarctic ecosystems. The physiology of both mosses and cyanobacteria is strongly influenced by environmental factors such as temperature and moisture, which directly affect N2 fixation rates.

Proximity to seabird colonies and water availability shape moss distributions in Antarctica

open access: yesEcography, Volume 2026, Issue 1, January 2026.
Understanding species distributions across Antarctica is crucial for biodiversity conservation under climate change, but continental‐scale analyses of key terrestrial species remain scarce. Here, we modelled distributions of 28 moss species across Antarctica using log‐Gaussian Cox process models and environmental covariates including topographic ...
