The Botanical Review, 2020 Struthiopteris (Blechnaceae) has recently been classified on the basis of molecular and morphological evidence, and some of its species are now included in the sister genus Spicantopsis. However, the lack of studies on several important morphological features impedes a sound assessment of their congruence with this new systematic arrangement, as well ...

Journal of Biogeography, Volume 52, Issue 8, August 2025.ABSTRACT Aim We sought to assess how phylogenetic patterns within the fern family Pteridaceae are related to the history of the Amazon Forest and the Brazilian Atlantic Forest, as well as the Dry Diagonal of South America. The age of taxa present in these regions was estimated, as well as those found in previously identified areas of endemism for the ...

A Global Assessment of Plant and Animal Community Responses to Forest Management Over Time
Global Change Biology, Volume 31, Issue 6, June 2025.Written Summary: We assessed the effects of seven forest management systems on biodiversity over time. We find that biodiversity responds more negatively to intensive than extensive forest management, but we also find that biodiversity can recover over time, particularly in intensively managed plantations and agroforests. ABSTRACT Transitions to forest

The Plant Journal, Volume 121, Issue 3, February 2025.SUMMARY DICER‐LIKE (DCL) proteins play a central role in plant small RNA (sRNA) biogenesis. The genome of the early land plant Marchantia polymorpha encodes four DCL proteins: MpDCL1a, MpDCL1b, MpDCL3, and MpDCL4. While MpDCL1a, MpDCL3 and MpDCL4 show high similarities to their orthologs in Physcomitrium patens and Arabidopsis thaliana, MpDCL1b shares ...
