Tracking the Dynamics of human Colonisation and Adaptation in Central Vanuatu: Preliminary Results From Excavation and Survey at Pangpang, East Efate

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 221-236, April 2026.
ABSTRACT In October 2022 an extensive archaeological landscape was identified by staff of the Vanuatu Cultural Centre at Pangpang on the east coast of Efate Island in central Vanuatu.

Cycads in vitro

open access: yesPlant Tissue Culture and Biotechnology, 2015
The Cycadales are a group of botanical and evolutionary importance; however, many species face the threat of extinction due to poaching and habitat destruction. The current investigation reviews previous work on in vitro production of cycads, which holds great potential for mass production and germplasm conservation of these unique plants ...

A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe–Mozambique) and the Significance of Open Habitats

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...

The Bufei Nashen Pill Alleviates COPD by Targeting Endoplasmic Reticulum Stress Through the PERK/eIF2α Signaling Pathway

open access: yesImmunity, Inflammation and Disease, Volume 14, Issue 4, April 2026.
ABSTRACT Background Evidence supporting the therapeutic efficacy of Bufei Nashen pill (BFNSP) for chronic obstructive pulmonary disease (COPD) is currently limited. We evaluated BFNSP's effects on COPD progression and elucidated its potential mechanisms through LC/MS analysis of its active components.

A modification to the SCAR (Sequence Characterized Amplified Region) method provides phylogenetic insights within Ceratozamia (Zamiaceae) Una modificación al método SCAR (Sequence Characterized Amplified Region) aporta entendimiento filogenético en Ceratozamia (Zamiaceae)

open access: yesRevista Mexicana de Biodiversidad, 2012
Phylogenetic relationships among closely related plant species are still problematic. DNA intergenic regions often are insufficiently variable to provide desired resolution or support. In this study, a modification to the Sequence Characterized Amplified

Culture-based and Sanger sequencing approaches to uncover the diversity of leaf-fungal endophytes in neotropical gymnosperms

open access: yesTecnociencia
Endophytic fungi play a crucial role in the survival and adaptation of their host plants. In recent decades, unprecedented diversity of endophytic fungi has been reported in angiosperms, but knowledge about this diversity in tropical gymnosperms is ...
