1. Both the phylogenetic structure and trait composition of flowering
plant communities may be expected to change with altitude. In particular,
floral colours are thought to vary with altitude because Hymenoptera
typically decline in importance as pollinators while Diptera and
Lepidoptera become more important at higher elevations. Thus, ecological
filtering among elevation zones and competitive processes among
co-occurring species within zones could influence the floral chromatic
cues present at low and high elevations. 2. We collected data from 107
species of native flowering plants in the Himalaya mountains of central
Nepal over an elevation range of 900-4100 m, which includes habitat
ranging from subtropical to subalpine within a relatively small
geographical area. 3. There was significant phylogenetic clustering in the
communities as a result of monocots, particularly orchids, which were
found overwhelmingly at lower elevations. Phylogenetic signal for floral
colours indicated that related species had colours that were more
disparate than expected under Brownian motion evolution. Floral colours
were significantly more diverse in the higher elevation subalpine zone
than in the subtropical zone. However, the chromatic cues at both
elevations were consistent with the hue discrimination abilities of the
trichromatic hymenopteran visual system. 4. Synthesis. Flower colour is
not highly differentiated between subtropical and subalpine vegetation due
to differences in the available orders of insect pollinators, or by the
rate or direction of color evolution in the lineages composing the two
communities. Differences in colour diversity between zones may reflect
differences in the ecologically available morphospace based on pollinator
species richness and the constancy of their foraging behaviour. The
chromatic signals present in Nepali species are similar to the signals
found in insect-pollinated floras of other regions of the world.
