Накратко на български

Взаимоотношенията между растенията, галните осци и техните природни врагове показват дали еволюцията на насекомите зависи повече от храната им или от хищниците. Анализът помага да се разбере как се структурират тези сложни биологични общности и как се развиват защитните механизми.

Evolution of Rose Gall Tritrophic Communities

The overall objective of this project is to develop and apply an analytical approach that allows discrimination between competing hypotheses for observed patterns of interaction in tritrophic communities of plants, herbivores and parasitoid natural enemies. At one extreme, the Sequential Radiation Hypothesis (SRH) sees herbivore-parasitoid interactions as driven from the 'bottom-up', by plant-herbivore interactions. The SRH predicts that diversification of herbivores will track diversification of their food plants, and that related herbivores (and related parasitoids) will be found on related plants. In contrast, the Tritrophic Niche Concept (TNC) sees a major role for 'top-down' effects resulting from parasitoid-imposed selection on herbivore traits. If parasitoids drive the evolution of herbivore defences, then these, rather than patterns at lower trophic levels, could structure herbivore-parasitoid interactions. We develop a generalisable statistical approach for analysis of tritrophic interactions, and illustrate its use by application to an unparalleled dataset for replicate real-world communities of plants, gall wasp herbivores and parasitoid natural enemies. Our approach combines trophic interaction, herbivore trait and phylogenetic data for all three trophic levels to address four questions: 1. Do plant-herbivore interactions match the predictions of the Sequential Radiation Hypothesis? 2. Are herbivore-parasitoid interactions structured by herbivore host plant associations (SRH), herbivore defence traits (TNC), or both of these? 3. Have herbivore defence traits evolved convergently in replicate natural communities? If herbivore defences target fundamental aspects of parasitoid attack behaviour, then the TNC predicts that they should. 4. Can we use statistical models to accurately predict the parasitoid assemblages associated with unsampled herbivore hosts?

Цел на проекта

Tritrophic communities of plants, insect herbivores and associated parasitoid natural enemies together comprise more than 50% of all described species, including both beneficial ecosystem service providers and major economic pests. A key aim in ecology is to understand the processes that form this spectacular diversity and its complex interactions. This project (RoseTriComm) aims to answer two key questions: (a) Do plant traits also influence the diversification and assemblage structure of natural enemies? (b) Do natural enemies exert their own ‘top-down’ effects on herbivore diversification and assemblage structure? Our approach will assess the support for these alternative paradigms using an unparalleled dataset that combines trophic interaction, trait and phylogenomic data for plants (roses, 80 species), herbivores (rose gall wasps, 50 species), and parasitoids (ca. 100 species) from North America and Europe. This innovative research is the first application of the co-phylogeny framework to a large scale tritrophic system, examining the role of traits in structuring interactions in a multicontinental context. Furthermore, RoseTriComm will allow us to develop an analytical framework that can be applied to understanding any tritrophic system’s diversity and assemblage structure. The ability to anticipate the cascading impacts of species gains or losses, is more important than ever when biodiversity is increasingly vulnerable to threats such as climatic change. Finally, RoseTriComm will contribute to train and strengthen the fellow’s research skills in project management and grant writing, expand his network of collaborators, produce high-impact publications, and enable research dissemination via conference communications and public outreach.
