Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl.

open access: yesChemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were

The Cinderella tree, Quillaja saponaria – A soap story

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 439-451, March 2026.
Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

Beyond species means – the intraspecific contribution to global wood density variation

open access: yesNew Phytologist, Volume 249, Issue 6, Page 2630-2651, March 2026.
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

New Cretaceous Paleomagnetic and Geochronologic Data From the Antarctic Peninsula: Constraints on the Pre‐Opening Tectonic Evolution of the Drake Passage

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

Late‐Stage Rift Evolution at Back Arc Basins: Insights From a Tomography Experiment at Orca Volcano, Bransfield Basin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Back‐arc basins provide insights into the processes governing the evolution of continental rifting to seafloor spreading. The Bransfield basin hosts a back arc rift that is hypothesized to be in the late stages of this transition. Orca volcano is a submarine volcano that lies on the most evolved portion of the rift.

Wildfires and Public Health: A Comprehensive Review of Human‐Centric Studies

open access: yesGeoHealth, Volume 10, Issue 2, February 2026.
Abstract In the last decade, wildfires have surged in frequency, as highlighted in the 2024 National Interagency Fire Center report, and continue to rise, making them a worldwide concern due to their environmental and public health impact. Climate change and shifting fire patterns contribute to this growing challenge.

Matching Multiple Backgrounds: Egg Camouflage Across Different Habitats in a Shorebird

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
We studied egg camouflage in Kentish plovers nesting in two visually distinct habitats, sandy beaches and salt marshes, in southern Spain. Despite initial expectations of local adaptation or compromise camouflage, the birds instead chose nest sites within each habitat that shared overlapping colour and visual texture characteristics, allowing effective

Effect of Chilean bark extracts on bacterial luminescence

open access: yes, 2018
Bioluminescence decrease of bacteria as a biological activity indicator for bark water extracts was determinate. Four Chilean barks were tested. A different reduction on bioluminescence depending on bark species was observed. Increasing time of thermal treatment of bark (24, 48, 72 and 144 hours with 103 degrees C) produced a reduction of the ...
