The oasis effect in an extremely hot and arid climate: The case of southern Israel
TLDR
Results obtained demonstrate that the settlement created an ‘oasis effect’, but its intensity was dependant on the combined influences of synoptic conditions, time of day and type of vegetation. Expand
The spectral quality of light is a key driver of photosynthesis and photoadaptation in Stylophora pistillata colonies from different depths in the Red Sea
TLDR
The results indicate that S. pistillata colonies are chromatically adapted to their surrounding light environment, with photoacclimation probably occurring via an increase in photosynthetic pigments rather than algal density. Expand
THE KINETICS OF THE PHOTOACCLIMATION RESPONSE OF NANNOCHLOROPSIS SP. (EUSTIGMATOPHYCEAE): A STUDY OF CHANGES IN ULTRASTRUCTURE AND PSU DENSITY
TLDR
It is found that the increase in the relative volume of the chloroplast during acclimation to LL (twofold) was accompanied by an increase in number of stacks and in the surface area of thylakoids per cell (2.5‐fold), and a partial sequence of the photoacclimation processes is proposed based on data and the derived rate constants.

Natural Antioxidants: Function and Sources
The definition of antioxidants, given in 1995 by Halliwell and Gutteridge, stated that an antioxidant is “any substance that, when present at low concentrations compared with that of an oxidizableExpand
Transparent Exopolymer Particles (TEP) link phytoplankton and bacterial production in the Gulf of Aqaba
TLDR
It is suggested that TEP acted to link carbon flux between the primary producers and heterotrophic bacteria, and that the downward movement of TEP from the upper water layers may be an important process in transferring organic carbon to deeper waters of the Gulf of Aquaba. Expand
Functional changes of the visual system of the damselfish Dascyllus marginatus along its bathymetric range
TLDR
It is found that deeper water fish responded to the optomotor test at lower light levels and also had more discriminating visual acuity in low light, which can increase their potential reactive distance. Expand
First record of the Indo-Pacific seaweed Codium arabicum Kütz. (Bryopsidales, Chlorophyta) in the Mediterranean Sea
TLDR
High water temperatures for most of the year and free habitat space appear to facilitate the successful settlement and establishment of this species, as has been the case for hundreds of other invasive Indo-Pacific organisms along the Israeli Mediterranean shore. Expand
Microbial rhodopsins on leaf surfaces of terrestrial plants.
TLDR
The findings, for the first time, point towards the potential coexistence of microbial rhodopsin-based phototrophy and plant chlorophyll-based photosynthesis, with the different pigments absorbing non-overlapping fractions of the light spectrum. Expand
Flashing light enhancement of photosynthesis and growth occurs when photochemistry and photoprotection are balanced in Dunaliella salina
TLDR
It is concluded that a slower activation of the VC takes place under balanced flashing light, when each flash is followed by a dark period long enough for utilization of the photons absorbed during the flash at a given irradiance. Expand
Underwater light field patterns in subtropical coastal waters: A case study from the Gulf of Eilat (Aqaba)
In this study, we describe the seasonal patterns and the depth dependence of the underwater distribution of ultraviolet radiation (UVR) and photosynthetically active radiation (PAR) in the Gulf ofExpand
