Obviously, combinations of shade-tolerant and light-demanding species can only exploit the complementarity when the light-demanding species is taller than the shade-tolerant species, and when this pattern is maintained as stand development progresses (Zenner et al. 2012).
It must be explained by a combination of shade with increased soil nutrients and/or water content.
When the sun's strong, use a combination of shade, clothes and at least SPF 15 sunscreen to protect your skin.
The result produced a distinct combination of shades, the first Chaumet collection dedicated to the art of enamel.
One type has an optical switching system that is a combination of the shade on the float and optical fibers arranged along the channel.
"Just as cinematic images appear to be real but are only combinations of light and shade, so is the universal variety a seeming delusion.
Simulation results showed that, using an optimum combination of glazings, shading devices and controllable electric lighting systems, the energy savings in perimeter spaces can be substantial.
A blush like my Mosaic Powder in Gleamer, with its combination of pink shades, is perfect for medium skin tones.
Nine groups of Holstein–Friesian cows (27 animals in total, 3 animals/group) were exposed to three treatment combinations: pair-wise simultaneous presentation of shade cloth that blocked: (1) 50 and 99%, (2) 25 and 50%, and (3) 25 and 99% of solar radiation.
Thus, on moist and fertile sites, where light is the limiting factor, combinations of light-demanding and shade-tolerant species may be most beneficial.
Combinations of light-demanding and shade-tolerant species, shallow- and deep-rooting species, early and late successional species, and mixtures with N2-fixing tree species are likely to successfully improve yields.
