Patterns in floral nectar characteristics of some bird-visited plant species from Costa Rica
Nectar samples from a wide range of flowers (120 samples, 112 species, 22 families) visited by hummingbirds (subfamilies Phaethorninae and Trochilinae) were collected over a wide range of elevationsExpand
Floral nectar sugar compositions of some south and Southeast Asian species
Floral nectars of 62 species native to south and southeast Asia were sampled opportunistically, mostly in Malaysia, and analyzed for sugar composition by HPLC. The sugar compositions of these nectarsExpand
Floral nectar sugar composition and pollinator type among new world genera in tribe Antirrhineae (Scrophulariaceae)
The floral nectar sugar compositions of 20 New World species from 10 genera and of five interspecific hybrids in tribe Antirrhineae have been analyzed using high-performance liquid chromatography.Expand
Effects of Temperature and Water Stress on Some Floral Nectar Characteristics in Ipomopsis longiflora (Polemoniaceae) under Controlled Conditions
Plants in laboratory experiments were exposed to constant day (16 h) temperatures of 20 C, 30 C, and 35 C with night temperatures of 20 C (8 h) and three levels of water stress (low, moderate, andExpand
Ornithophily among the Hawaiian Lobelioideae (Campanulaceae): evidence from floral nectar sugar compositions
Data on the sugar compositions of floral nectars were used to test the hypothesis that the Hawaiian Lobelioideae (Campanulaceae) were pollinated by nectarivorous passerine birds (Fringillidae subfam.Expand
VARIATION IN NECTAR SUGAR COMPOSITION AT THE INTRAPLANT LEVEL IN IPOMOPSIS LONGIFLORA (POLEMONIACEAE)
The nectar sugar composition of individual flowers from single plants in both greenhouse and field populations was determined by High-Performance Liquid Chromatography (HPLC). Intraplant variabilityExpand
Similarity and Apparent Convergence in the Nectar-Sugar Composition of Some Hummingbird-Pollinated Flowers
The nectar-sugar composition of 40 species of purportedly hummingbird- pollinated plants in 12 families was determined by high-performance liquid chromatography. The distribution of relativeExpand
