Spatial Distribution and Conservation Prioritization of Medicinal Gymnosperms in China Using an Optimal Set‐Cover Approach

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The study identified 41 priority conservation grids and 8 critical conservation gaps not covered by national reserves for medicinal gymnosperms. We proposed a practical, multi‐dimensional framework for their conservation. ABSTRACT To elucidate the geographical distribution patterns and hotspots of medicinal gymnosperms in China, providing a scientific ...

Synergistic Effect of Deoxyanthocyanins from Symbiotic Fern Azolla spp. on hrmA Gene Induction in the Cyanobacterium Nostoc punctiforme

Molecular Plant-Microbe Interactions, 2002
The hrmA gene of the N2-fixing cyanobacterium Nostoc punctiforme functions in repressing the formation of transitory motile filaments, termed hormogonia, by plant-associated vegetative filaments.

Rethinking cycad metabolite research

Communicative & Integrative Biology, 2011
Cycads are among the most ancient of extant Spermatophytes, and are known for their numerous pharmacologically active compounds. One compound in particular, β-methylamino-L-alanine (BMAA), has been implicated as the cause of amyotrophic lateral sclerosis/Parkinson dementia complex (ALS/PDC) on Guam.

Complete Genomes of Symbiotic Cyanobacteria Clarify the Evolution of Vanadium-Nitrogenase. [PDF]

, 2019
Plant endosymbiosis with nitrogen-fixing cyanobacteria has independently evolved in diverse plant lineages, offering a unique window to study the evolution and genetics of plant-microbe interaction.

New Insights Into the Distribution of Australian Butterflies (Lepidoptera: Papilionoidea) Provided by Citizen Science

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Butterflies are one of Australia's most popular and well‐studied invertebrate groups. Much butterfly research in the country is either led or supported by amateur entomologists and citizen scientists, and yet despite this, the recent and dramatic increase in the volume of publicly accessible citizen science butterfly observations has received ...

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

Archaeology 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. It included midden deposits on the banks of the Pangpang River near the sea at Forari Bay where Lapita and Early Erueti‐style pottery sherds were recovered.

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

Ecology 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

Immunity, 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.

Axial and Radial Spatial Patterns of Non-Structural Carbohydrates in Cycas micronesica Stems

Plants, 2018
The pachycaulous stem of arborescent cycad species exhibits unique traits and has received limited research. To date, nothing is known about the axial and radial spatial patterns of non-structural resources within cycad stems. Cycas micronesica K.D. Hill
