“…A latitudinal analysis of the distribution of solar energy maxima during the year showed that in the northern hemisphere, the distribution of radiation maxima is symmetric for the month of June. So, July is symmetric to May, April to August, September is similar to March (points of autumn and spring equinox), October to February, November to January, and December in the southern hemisphere is an axis of symmetry, as well as June in the northern hemisphere (Britton, 1986).…”

“…At the summer solstice, the presented pattern shifts by 23° toward the North Pole, and at the winter solstice, it shifts by 23° toward the South Pole. This shift determines the seasonal specificity of the corolla coloration in flowering plants (Britton, 1986). The longwave boundary of solar radiation can also cause the appearance of adaptive white surface due to the adaptation to numerous peaks in the IR range (Figure 1).…”

This paper investigated latitudinal and seasonal variations in the qualitative characteristics of solar radiation (spectral composition, position of the maximum and short-wave boundary) in the ultraviolet and visible regions. It has been established that, depending on the latitude and season, the peaks λ=415 nm, λ=480 nm, λ=500-505 nm, λ=525-535 nm, λ=575-590 nm, λ=610-700 nm, λ=722.5 nm, λ=735 nm, λ=740 nm, λ=760 nm and λ=765 nm may appear. Coloring surfaces variants whose absorption spectrum corresponds to these peaks are considered. It has been suggested that the coloration of the corolla in flowering plants is the result of adaptation to the solar spectrum maximum and may determine convergent seasonal and latitudinal coloration in species of flowering plants.

“…1 A number of reviews have dealt with natural sesquiterpenoids, 2-7 diterpenoids, [8][9][10][11] sesterterpenoids, 12,13 triterpenoids, [14][15][16][17][18] carotenoids and polyterpenoids. [19][20][21][22][23] Other general reviews are: "Marine natural products". [24][25][26][27][28][29][30] In this review, we show structures of linear furano-and pyrroloterpenoids, and previously reported linear furano-and pyrroloterpenoids where there has been a structural revision or a newly established stereochemistry, previously reported linear furano-and pyrroloterpenoids for which rst syntheses, new bioactivities, or new sources are described are referenced, and this review also added the furanotetraterpenoids and furanocarotenoids.…”
