Are insect pollinators more generalist than insect herbivores?
Recent community-level studies have acknowledged that generalist species are more widespread than previously thought and highlighted their preponderant impact on community functioning and evolution. It is suggested that the type of interaction, trophic versus mutualistic, should affect species generalization level; however, no direct comparison has been made yet. Here, we performed such a compa...
متن کاملLearning in Insect Pollinators and Herbivores.
The relationship between plants and insects is influenced by insects' behavioral decisions during foraging and oviposition. In mutualistic pollinators and antagonistic herbivores, past experience (learning) affects such decisions, which ultimately can impact plant fitness. The higher levels of dietary generalism in pollinators than in herbivores may be an explanation for the differences in lear...
متن کاملHairiness: the missing link between pollinators and pollination
BACKGROUND Functional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, traits are widely used in ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species that are at best only weakly associated with functions. Animal-mediated pollination is a key ecosystem function and is likely to be i...
متن کاملPollination efficiency and the evolution of specialized deceptive pollination systems.
The ultimate causes of evolution of highly specialized pollination systems are little understood. We investigated the relationship between specialization and pollination efficiency, defined as the proportion of pollinated flowers relative to those that experienced pollen removal, using orchids with different pollination strategies as a model system. Rewarding orchids showed the highest pollinat...
متن کاملDiversity and abundance of insect pollinators on Allium cepa L
Field experiment was conducted at CCS Haryana Agricultural University, Hisar during 2009-10 to investigate the diversity and abundance of insect pollinators on Allium cepa L. and correlate their incidence in relation to the abiotic environmental factors. Hymenopterans were found to be the most abundant (60%) followed by Lepidoptera, Diptera and Coleoptera. Variation in abundance was recorded ov...
