An experimental test in an 'ornithophilous
' African Protca.
Culiseta longiareolata, ornithophilous
species comes in second rank with a rate of 32.39%.
The pollination of Bromelia antiacantha (Bromeliaceae) in Southeastern Brazil: Ornithophilous
versus Melittophilous features.
The resource density (RD) of ornithophilous
and non-ornithophilous resources available each month for the hummingbirds in each of the sample areas was calculated by the following Equation 1:
Floral isolation between ornithophilous
and sphingophilous species of Ipomopsis and Aquilegia.
flowers are large, tend to be red, deep seated with concealed nectar.
However, the present values of nectar volume and sugar concentration are greater than those reported for other ornithophilous
flowers, both from high mountain and low land (Waser, 1979; Willmer and Corbet, 1981; Roubik et al., 1985; Colwell, 1995; Ariz-mendi et al., 1996; Lange et al., 2000; Navarro, 2001).
In the high Andean region of Ancash the greatest diversity offlowers ornithophilous
is in shrublands, in contrast to rocky areas and grasslands, in those that we find stands of bromelias of the genera Puya whose nectar could constitute an important resource for high Andean hummingbirds in these habitat types.
