Herbivory as an important selective force in the evolution of floral traits and pollinator shifts
Floral trait evolution is frequently attributed to pollinator-mediated selection but herbivores can play a key role in shaping plant reproductive biology. Here we examine the role of florivores in driving floral trait evolution and pollinator shifts in a recently radiated clade of flowering plants, Oenothera sect. Calylophus We compare florivory by a specialist, internal feeder, Mompha, on clos...
متن کاملAn obligate pollination mutualism and reciprocal diversification in the tree genus Glochidion (Euphorbiaceae).
Highly coevolved pollination mutualism accompanied by reciprocal diversification has been known in only two plant genera, Ficus (Moraceae) and Yucca (Agavaceae), which are pollinated exclusively by obligate seed-parasitic wasps and moths, respectively. An additional, highly diversified, species-specific pollination mutualism between a monoecious tree genus, Glochidion (Euphorbiaceae), and a mot...
متن کاملThe genus Helvella in Iran
This study is a review on the genus Helvella (Pezizales, Helvellaceae) in Iran. Study on samples deposited in Iran fungal herbarium along with the fresh materials collected by the author revealed that seven species of Helvella, H. acetabulum, H. atra, H. crispa, H. elastica, H. ephippium, H. lacunosa and H. leucopus (as H. monachella) have already been reported from Iran. Three other species vi...
متن کاملFirst record of bat-pollination in the species-rich genus Tillandsia (Bromeliaceae).
BACKGROUND AND AIMS Bromeliaceae is a species-rich neotropical plant family that uses a variety of pollinators, principally vertebrates. Tillandsia is the most diverse genus, and includes more than one-third of all bromeliad species. Within this genus, the majority of species rely on diurnal pollination by hummingbirds; however, the flowers of some Tillandsia species show some characteristics t...
متن کاملComparative biology of pollination systems in the African-Malagasy genus Brownleea (Brownleeinae: Orchidaceae)
The role of pollinators in the evolution of the African-Malagasy orchid genus Brownleea (Brownleeinae) was investigated. Taxa show specialization for pollination by bees (B. parviflora, B. recurvata), short-proboscid flies (B. galpinii), and long-proboscid flies (B. macroceras, B. coerulea). All species in the genus produce nectar, but some (B. coerulea, B. galpinii) appear to mimic flowers of ...
