The Fifth Phase of the Radiation Transfer Model Intercomparison Exercise (RAMI-V): Experiment Description and Results on Actual Canopy Scenarios

Journal of Remote Sensing
This paper presents the latest results of the radiation transfer model intercomparison (RAMI) of the realistic vegetation scenarios. RAMI-V included the same one-dimensional (1D) and 3D scenes of RAMI-IV phase and 2 new realistic ones, defined through a ...

Bio‐inspired artificial retina with receptive fields for in‐sensor multiply‐and‐accumulate operations

InfoMat, EarlyView.
We developed a bio‐inspired artificial retina in which curved artificial receptive fields composed of perovskite photoconductors perform multiply‐and‐accumulate operations through in‐sensor computing. This architecture simultaneously realized the structural efficiency of human eyes (compact single‐lens imaging system) and functional advantages of ...

Morpho‐Anatomical and HPTLC Investigations of Lysimachia nummularia L. (Primulaceae) Grown in Switzerland

Microscopy Research and Technique, EarlyView.
This research provides a complete morphoanatomical description of Lysimachia nummularia, as well as a HPTLC profile. Standard techniques of light and scanning electron microscopies, as well as standard techniques of HPTLC, were used. ABSTRACT Primulaceae are distributed all over the world, encompassing around 2590 species.

Comparison of optical and digital techniques for light microclimate assessment in the Paneveggio Forest, Trentino, Italy

Forest@, 2006
Hemispherical photography is a widely used tool for the indirect estimation of forest light environment and quantification of canopy openness, LAI, and direct and diffuse canopy light transmittance.

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

Nordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Pinguicula brendae (Lentibulariaceae) sp. nov., a carnivorous plant from a tropical montane cloud forest in Hidalgo, Mexico

Nordic Journal of Botany, EarlyView.
A new species of Lentibulariaceae, Pinguicula brendae Rodríguez‐Ramírez, H.Shimai & A.R. Andrés‐Hernández, is described based on its unique morphological characteristics. This species is restricted to limestone rock walls in the San Bartolo Tutotepec municipality, central‐eastern Hidalgo, Mexico, where it inhabits a single locality on vertical, north ...

Estimation of vegetation biophysical parameters in grasslands and crops in Chile through hemispheric digital photography by a GoPro camera

Revista de Teledetección, 2018
The estimation of the biophysical parameters of vegetation such as LAI (Leaf Area Index), FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) and FCOVER (Fraction of Green Vegetation) have many climatic, hydrologic, ecosystem and silvo-agricultural applications.

Meyna grisea (King & Gamble) Robyns and Meyna peltata Robyns (Rubiaceae: Vanguerieae) – a new record of two ethnobotanically significant fruit trees from Manipur, India

Nordic Journal of Botany, EarlyView.
Meyna grisea and M. peltata, two new records from Imphal Valley, Manipur, India, characterised by a capitate stigma with 4–5 divergent, spreading lobes on a globose base, and a prominent peltate stigma, respectively, are described and illustrated here. Photographs, key to the species, along with their coordinates and diagnostic characters in comparison

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

Oikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly
