BACKGROUND Most spectral data for the amphibian integument are limited to the visible spectrum of light and have been collected using point measurements with low spatial resolution. In the present study a dual camera setup consisting of two push broom hyperspectral imaging systems was employed, which produces reflectance images between 400 and 2500 nm with high spectral and spatial resolution a...

The accumulation of ions due to increased salinity in the soil is one major abiotic stressors cultivated plants that negatively affect their productivity. model plant, Medicago truncatula, only species has been extensively studied, whereas research into adaptation two important forage legumes, M. sativa and arborea, limited. In present study, expression six genes, namely SOS1, SOS3, NHX2, AKT, ...

Wrightia arborea (Br.) (Family-Apocynaceae), locally known as Sathkurchi, is a small deciduous tree with branches and densely velvety leaves. This study was designed to investigate the antioxidant anti tumor activities of leaves W. arborea.
 Antioxidant potential evaluated in vitro by DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging- reducing power- assay method which concentration dependen...

Marine algae rely on currents and waves to replenish the nutrients required for photosynthesis. The interaction of algal blades with flow often involves dynamic reorientations of the blade surface (pitching and flapping) that may in turn affect nutrient flux. As a first step toward understanding the consequences of blade motion, we explore the effect of oscillatory pitching on the flux to a fla...

The ecophysiologic role of fog in the evergreen heath-laurel 'laurisilva' cloud forests of the Canary Islands has not been unequivocally demonstrated, although it is generally assumed that fog water is important for the survival and the distribution of this relict paleoecosystem of the North Atlantic Macaronesian archipelagos. To determine the role of fog in this ecosystem, we combined direct t...

Four polyphenols were isolated and purified from a brown alga Eisenia arborea. These phlorotannin compounds showed strong radical scavenging some enzyme inhibitory activities. All of the antioxidative, acetylcholinesterase butyrylcholinesterase inhibitory, tyrosinase inhbibitory activities at 100 μg/mL. Dieckol PFF inhibited butyrylcholinesterase, new target for treatment Alzheimer’s disease, v...

Recently developed acoustic technologies - like automatic recording units - allow the recording of long sequences in natural environments. These devices are used for biodiversity survey but they could also help researchers to estimate global signal variability at various (individual, population, species) scales. While sexually-selected signals are expected to show a low intra-individual variabi...
