RECOGNITION OF THE GENUS MYRIOPTERIS (PTERIDACEAE, POLYPODIOPSIDA) IN BRAZIL

Darwiniana, nueva serie, 2019
In the present work, the genus Myriopteris is mentioned for the first time for Brazil, represented by M. myriophylla, a species of wide distribution in the American continent, from Mexico to Argentina, but never before verified for this country. Furthermore, we provide a description of the sole species found, along with an image and notes.

Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

Ecography, Volume 2025, Issue 11, November 2025.
About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...

Speciation, dispersal and the build‐up of fern diversity in the American tropics

Ecography, Volume 2025, Issue 11, November 2025.
Understanding how the remarkable biodiversity of the American tropics developed has been a long‐standing question, yet knowledge gaps remain. Previous studies examined the roles of bioregions in shaping diversity patterns but often overlooked speciation, a critical driver of species richness, and insufficiently accounted for temporal changes in ...

TRB proteins in moss reveal their evolutionarily conserved roles in plant development and telomere maintenance

The Plant Journal, Volume 124, Issue 3, November 2025.
Significance Statement TRB proteins in the moss P. patens are essential for normal development, telomere maintenance, and transcriptional regulation. Our findings demonstrate the evolutionary conservation of TRB functions across land plants and highlight their ancient origin in streptophytes.

Plant fossils in the Carboniferous beds of the motorway route at Bizovik

Geologija, 2002
Study of fossil plants that were found during construction work of the Eastern Ljubljana motorway at Bizovik demonstrated that similar plants flourished in the uniform Euroamerican floristic area that extended in the Late Carboniferous from the present ...

Micromorphology of fern spores as a tool in taxonomy of East-Central European species from the family Aspleniaceae (Polypodiopsida)

Acta Societatis Botanicorum Poloniae
The family Aspleniaceae consists of ca. 730 fern species found primarily in the tropics but present also in the temperate zone. Recently, researchers have been increasingly interested in spore morphology, as it provides valuable information used in ...

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

Identification and characterization of DICER‐LIKE genes and their roles in Marchantia polymorpha development and salt stress response

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 ...
