Decay stages of Jurassic wood debris from Scotland: evidence for the coevolution of fungal rot, arthropods and the nurse log strategy

New Phytologist, Volume 248, Issue 3, Page 1557-1571, November 2025.
Summary A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for young tree species, leading to this type of seedbed being termed ‘nurse logs’.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Chromosome‐level genome assembly and annotation of Ulmus minor reveal dynamic intrageneric clusters of resistance genes

The Plant Genome, Volume 18, Issue 3, September 2025.
Abstract The field elm (Ulmus minor) is an emblematic species of the European landscape, which has been severely affected by Dutch elm disease (DED) since the 20th century. To support restoration and conservation of this species and congeners, we present a de novo assembly and annotation of a wild genotype tested positive for DED resistance, along with
