Why do pollinators visit proportionally fewer flowers in large patches?
Pollinators collect resources that are patchy, since flowers are usually aggregated on several spatial scales. Empirical studies have established that pollinators almost invariably visit a smaller proportion of flowers as patch size increases. This has not been adequately explained. Here I present data on the payoff curve achieved by bumblebees, Bombus lapidarius, when visiting patches containi...
متن کاملHow do the pollinators' flower preferences affect the features of the pollination network?
All pollinators are classified as either generalists or specialists, depending on the variety of flower species that they pollinate. This research project strives to understand how these generalist and specialist pollinators' flower preferences affect the features of the resulting pollination network. More specifically, it aims to quantify and compare the ecological health of the pollination ne...
متن کاملAdaptation of flower and fruit colours to multiple, distinct mutualists.
Communication in plant-animal mutualisms frequently involves multiple perceivers. A fundamental uncertainty is whether and how species adapt to communicate with groups of mutualists having distinct sensory abilities. We quantified the colour conspicuousness of flowers and fruits originating from one European and two South American plant communities, using visual models of pollinators (bee and f...
متن کاملThe role of pollinators in maintaining variation in flower colour in the Rocky Mountain columbine, Aquilegia coerulea.
BACKGROUND AND AIMS Flower colour varies within and among populations of the Rocky Mountain columbine, Aquilegia coerulea, in conjunction with the abundance of its two major pollinators, hawkmoths and bumble-bees. This study seeks to understand whether the choice of flower colour by these major pollinators can help explain the variation in flower colour observed in A. coerulea populations. ME...
متن کاملIndividuals with psychometric schizotypy show similar social but not physical anhedonia to patients with schizophrenia.
Very few studies have examined physical and social anhedonia across the spectrum of schizophrenia. In the present study, we recruited three groups of participants (n=84 in each group): patients with schizophrenia, schizotypy and non-schizotypy as assessed by the Schizotypal Personality Questionnaire (SPQ). All participants completed the self-reported trait anhedonia scales (the Revised Physical...
