Does Specialized Pollination Impede Plant Invasions?
Generalized pollination systems and autonomous self fertilization are traits that have been linked with plant invasiveness. However, whether specialized pollination requirements pose a significant barrier to plant invasions is not yet clear. Likewise, the contribution of pollinators to the fecundity of facultatively self pollinating invasive plant species is poorly understood. We addressed thes...
متن کاملUpdate on Recombinational Cloning with Plant Gateway Vectors Recombinational Cloning with Plant Gateway Vectors
The study of biological systems relies to a large extent on DNA cloning technologies enabling the analysis of recombinant genes through transgenic research. In this context, the advent of recombinational cloning methods was a significant progress because DNA fragments can now be assembled regardless of their sequence. In particular, the Gateway system was designed to join fragments in a predefi...
متن کاملHost Effects On Herbivory and Pollination in a Hemiparasitic Plant
The indirect effects of hosts on interactions between parasites and other species are not well understood, and it may be difficult to predict the outcome of host species effects on parasite performance due to the complexity of potential direct and indirect effects. For example, parasitic plants obtain defensive compounds as well as nutrients from their hosts, and thus many attributes of parasit...
متن کاملEvolutionary breakdown of pollination specialization in a Caribbean plant radiation.
• Ecological generalization is postulated to be the rule in plant-pollinator interactions; however, the evolution of generalized flowers from specialized ancestors has rarely been demonstrated. This study examines the evolution of pollination and breeding systems in the tribe Gesnerieae (Gesneriaceae), an Antillean plant radiation that includes specialized and generalized species. • Phylogeneti...
متن کاملRequirements for plant coexistence through pollination niche partitioning.
Plant-pollinator interactions are often thought to have been a decisive factor in the diversification of flowering plants, but to be of little or no importance for the maintenance of existing plant diversity. In a recent opinion paper, Pauw (2013 Trends Ecol. Evol. 28, 30-37. (doi:10.1016/j.tree.2012.07.019)) challenged this view by proposing a mechanism of diversity maintenance based on pollin...
