Pollinators, mates and Allee effects: the importance of self-pollination for fecundity in an invasive lily
1. Ability to self-fertilize is correlated with invasiveness in several introduced floras, and this has been attributed to its mitigating effect on fecundity when pollinator visitation and mate availability are inadequate. Cross-pollination opportunities are expected to be most limited in isolated individuals and small populations, both typical of the leading edge of an invasion. Thus, self-pol...
متن کاملThe phytochemistry and ethnobotany of the southern African genus Eucomis (Hyacinthaceae: Hyacinthoideae)
The endemic African genus Eucomis (Hyacinthaceae) has long been one of the most highly regarded sources of ethnomedicines in southern Africa, attracting the attentions of toxicologists, pharmacologists and phytochemists. This chapter reviews the ethnobotany of this small group of fourteen described taxa (ten species), and the known phytochemistry. Six taxa (five species) have been recorded used...
متن کاملAntiangiogenic Activity and Cytotoxicity of Triterpenoids and Homoisoflavonoids from Massonia pustulata and Massonia bifolia.
The Hyacinthaceae family (sensu APGII), with approximately 900 species in around 70 genera, plays a significant role in traditional medicine in Africa as well as across Europe and the Middle and Far East. The dichloromethane extract of the bulbs of Massonia pustulata (Hyacinthaceae sensu APGII) yielded two known homoisoflavonoids, (R)-5-hydroxy-3-(4-hydroxybenzyl)-7-methoxy-4-chromanone 1: and ...
متن کاملThe pollination niche and its role in the diversification and maintenance of the southern African flora.
The flora of southern Africa has exceptional species richness and endemism, making it an ideal system for studying the patterns and processes of evolutionary diversification. Using a wealth of recent case studies, I examine the evidence for pollinator-driven diversification in this flora. Pollination systems, which represent available niches for ecological diversification, are characterized in ...
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 ...
