Dos especies nuevas de calathea (Marantaceae) de la Amozonia Colombiana [PDF]

Caldasia, 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.

Responses of Calathea species in different growing media

Nigerian Journal of Horticultural Science, 2002
Pot experiments were conducted at the National Horticultural Research Institute (NIHORT), Ibadan to investigate the most suitable medium for the growing of Calathea species. Four Calathea species namely: C. ornata; C.nigerica; C. princeps and C.zebrina, were planted each in three growing media made up of top soil; top soil and poultry manure (3:1) and ...

Calathea multispicata (Marantaceae), a new species endemic to Colombia

Journal of the Botanical Research Institute of Texas, 2019
Calathea multispicata H. Kenn. & M. Serna, endemic to Colombia, is described as new. Currently, it is known only from the Department of Valle de Cauca in premontane (1300–1800 m) pluvial forest habitat. Calathea multispicata is characterized by the presence of only two leaves per shoot, one basal and one cauline and the numerous relatively small ...

Pyriculariopsis calatheae sp. nov., a novel anamorphic hyphomycete from the Atlantic forest of Brazil causing leaf spots on Calathea longifolia

Mycological Progress, 2010
The new species Pyriculariopsis calatheae is described causing leaf spots on Calathea longifolia (Marantaceae). It represents an addition to the mycobiota of the tropical seasonal semi-deciduous montane forest, a component of the Brazilian Atlantic forest and a highly threatened ecosystem.

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

Ecol 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.

Robotic Materials With Bioinspired Microstructures for High Sensitivity and Fast Actuation. [PDF]

Adv Sci (Weinh)
In the review paper, design rationale and approaches for bioinspired sensors and actuators in robotics applications are presented. These bioinspired microstructure strategies implemented in both can improve the performance in several ways. Also, recent ideas and innovations that embed robotic materials with logic and computation with it are part of the

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

Adv 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]

FEBS 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.
