Phytochemical Screening, Antibacterial Activity, and Toxicity of Calathea lutea Leaf Extracts. [PDF]

open access: yesPrev Nutr Food Sci
In Colombia, there is a long tradition of using bijao (Calathea lutea) leaves to package or wrap various foods. However, scientific studies on C. lutea are limited, and research to evaluate its toxicity and/or antibacterial activity has not yet been conducted.

Cupric Oxide Nanostructures from Plasma Surface Modification of Copper [PDF]

open access: yesBiomimetics, 2019
Taking inspiration from the hydrophilic and superhydrophilic properties observed from the nanostructures present on the leaves of plants such as Alocasia odora, Calathea zebrina, and Ruelia devosiana, we were able to synthesize cupric oxide (CuO ...

Dos especies nuevas de calathea (Marantaceae) de la Amozonia Colombiana

open access: yesCaldasia, 2000
Two new species of Marantaceae from Amazonian Colombia are described and illustrated: Calathea caquetensis and C. compacta. C. caquetensis is apparently related to C. attenuata and C. silvosa. C. compacta seems to be related to C. ecuminata, C.

Leaf Movements of Indoor Plants Monitored by Terrestrial LiDAR [PDF]

open access: yesFrontiers in Plant Science, 2018
Plant leaf movement is induced by some combination of different external and internal stimuli. Detailed geometric characterization of such movement is expected to improve understanding of these mechanisms.

Structured Demographic Buffering: A Framework to Explore the Environmental Components and Demographic Mechanisms Underlying Demographic Buffering. [PDF]

open access: yesEcol Lett
Demographic buffering quantifies the degree to which a population's demographic rates reduce the negative impacts of environmental stochasticity. Here, we show that temporal variance and autocorrelation impact demographic buffering through different mechanisms. ABSTRACT Environmental stochasticity is a key determinant of population viability.

Anti-Motion Artifacts Iontronic Sensor for Long-Term Accurate Fingertip Pulse Monitoring. [PDF]

open access: yesAdv Sci (Weinh)
Flexible pressure sensors are essential for pulse monitoring and cardiovascular disease diagnosis but are affected by motion artifacts (MAs) due to stretching stress. The S‐smooth sensor with a soft‐hard stretchable interface that dissipates energy, reducing MAs by 90% is developed.

Photosynthesis under far-red light-evolutionary adaptations and bioengineering of light-harvesting complexes. [PDF]

open access: yesFEBS Lett
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.
