Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

Superhydrophobicity in perfection: the outstanding properties of the lotus leaf

open access: yesBeilstein Journal of Nanotechnology, 2011
Lotus leaves have become an icon for superhydrophobicity and self-cleaning surfaces, and have led to the concept of the ‘Lotus effect’. Although many other plants have superhydrophobic surfaces with almost similar contact angles, the lotus shows better ...

Detected Shifts Towards Drought‐Adaptive Strategies in the Amazon Forest Over the Last Four Decades

open access: yesGlobal Change Biology, Volume 32, Issue 2, February 2026.
Amazon forests are facing hotter, drier conditions, and we used 40 years of satellite data to look for early signs of ecological change. Combining satellite observations with leaf measurements from more than 3000 trees, we show that many forests now show smaller dry‐season fluctuations in canopy colour—especially in the southern and eastern Amazon ...

Response to Selection for Unique Epicuticular Wax Profile on the Semi-glossy Foliage of Onion

open access: yesJournal of the American Society for Horticultural Science
Epicuticular waxes on onion (Allium cepa) foliage offer protection against water loss, pathogens, and pests. Onion leaves with a light green color are referred to as “glossy” and have less total wax compared with that of darker blue-green (“waxy ...

Molecular study of lipids in humic acids by sequential chemical degradation [PDF]

open access: yes, 2009
Lipidy v půdě vykazují poměrně vysokou resistenci k biodegradaci, mohou proto tak zajistit informace o zdrojích organické hmoty a diagenetických procesech. Půdní organická hmota je vysoce heterogenní a vyskytují se v ní různé dynamické systémy.

Use of portable devices and confocal Raman spectrometers at different wavelength to obtain the spectral information of the main organic components in tomatoes (Solanum Lycopersicum) fruits [PDF]

open access: yes, 2013
Tomato (Solanum lycopersicum) fruit samples, in two ripening stages, ripe (red) and unripe (green), collected from a cultivar in the North of Spain (Barrika, Basque Country), were analyzed directly, without any sample pretreatment, with two different ...
