Question
(see image attached)
a) In what ways are floral traits similar or different between hawkmoth and bat pollination syndromes
b) In what ways are floral traits similar or different between bee and bat pollination syndromes
c) Which pollinator shift is more likely to lead to reproductive isolation between populations that have the ancestral pollinator and populations that have bat pollinators?
a) hawkmoth to bat
b) bee to bat
and why? / rationale

Transcribed Image Text:Among pollinators, bats are relatively large bodied, fly further on foraging bouts and
require larger quantities of nectar to sustain them. Bat pollination has evolved several
times in the New World from ancestral bee, or hawkmoth pollination syndromes.
