Ecological interactions have been acknowledged to play a key role in shaping biodiversity. Yet a major challenge for evolutionary biology is to understand the role of ecological interactions in shaping trait evolution when progressing from pairs of interacting species to multispecies interaction networks. Here we introduce an approach that integrates coevolutionary dynamics and network structure. Our results show that non-interacting species can be as important as directly interacting species… Expand

Figures and Topics from this paper

The geographic mosaic of coevolution in mutualistic networks
TLDR
It is shown that gene flow has the surprising effect of favoring trait matching, especially among generalist species in species-rich networks typical of pollination and seed dispersal interactions, and that the progressive loss of gene flow associated with habitat fragmentation may undermine coadaptation in mutualisms. Expand
Genetic correlations and ecological networks shape coevolving mutualisms.
TLDR
It is shown that genetic correlations may determine the pace of coevolutionary change, affect species abundances and fuel divergence among populations of the same species, but this trait divergence promoted by genetic correlations is partially buffered by the nested structure of species-rich mutualisms. Expand
The role of indirect effects in coevolution as mutualism transitions into antagonism
TLDR
It is shown that as mutualistic networks shift to antagonistic, selection imposed by direct partners begins to outweigh that imposed by indirect partners and this weakening of indirect effects is associated with communities losing their tight integration of traits and increasing their rate of adaptation. Expand
Coevolution by different functional mechanisms modulates the structure and dynamics of antagonistic and mutualistic networks
TLDR
Adaptive network models are built to explore the potential role of coevolution by two functional mechanisms, trait matching and exploitation barrier, in driving trait evolution and the structure of interaction networks and indicate that coev evolutionary models better reproduce the network structure of antagonisms than those of mutualisms and that different functional mechanisms may favor the persistence of antagonistic and mutualistic interacting assemblages. Expand
Eco-evolutionary feedbacks promote fluctuating selection and long-term stability of antagonistic networks
TLDR
This work shows that, if selection due to antagonistic interactions is stronger than other selective pressures, eco-evolutionary feedbacks lead to higher mean species abundances and lower temporal variation in abundances, and presents a theoretical link between the study of the species persistence and coevolution in networks of interacting species. Expand
Inferring coevolution in a plant–pollinator network
TLDR
By dissecting the complexity of an interaction network it is shown that coevolution may partially shape functional morphology of interaction partners, thus providing the closest evidence to date of mutualistic adaptation of organisms within a community. Expand
Coevolutionary dynamics shape the structure of bacteria‐phage infection networks
TLDR
This study quantified experimentally to what extent coevolutionary dynamics lead to contrasting patterns in the architecture of bacteria–phage infection networks, and found that interactions between coevolving bacteria and phages become less nested over time under fluctuating dynamics, and more nested under arms race dynamics. Expand
Measuring Coevolutionary Dynamics in Species-Rich Communities.
TLDR
It is proposed ways that such data can be complemented by genomic information and linked back to extant communities via network structure, and avenues for new theoretical work to strengthen these connections are suggested. Expand
Uncovering indirect interactions in bipartite ecological networks
TLDR
Simulations are used to show how consideration of indirect interactions can highlight ecologically important differences missed by the current index paradigm, and this finding is extended to empirical plant-pollinator communities, showing how two bee species, with similar direct interactions, differ in how specialised their competitors are. Expand
The indirect paths to cascading effects of extinctions in mutualistic networks.
TLDR
This work estimates indirect effects in plant-pollinator networks and finds that even those species with several direct interactions may have much of their influence over others through long indirect paths, allowing predicting species' vulnerability to the cascading effects of an extinction event.

Evolution and coevolution in mutualistic networks.
TLDR
It is predicted that worldwide shifts in the occurrence of super-generalists will alter how coevolution shapes webs of interacting species, and introduced species such as honeybees will favour trait convergence in invaded communities, whereas the loss of large frugivores will lead to increased trait dissimilarity in tropical ecosystems.

COEVOLUTION AND THE ARCHITECTURE OF MUTUALISTIC NETWORKS
Although coevolution is widely recognized as an important evolutionary process for pairs of reciprocally specialized species, its importance within species‐rich communities of generalized species hasExpand
Mutualistic Interactions Drive Ecological Niche Convergence in a Diverse Butterfly Community
TLDR
The results show that phenotype and ecology are strongly linked and support the idea that mimicry can cause ecological speciation through multiple cascading effects on species' biology, implying that ecological communities are adaptively assembled to a much greater degree than commonly suspected.

The ecological and evolutionary implications of merging different types of networks.
TLDR
This work outlines a conceptual framework for studying networks composed of more than one type of interaction, highlighting key questions and research areas that would benefit from their study. Expand
Non-random coextinctions in phylogenetically structured mutualistic networks
TLDR
This work uses phylogenetic methods to show that the phylogenetic relationships of species predict the number of interactions they exhibit in more than one-third of the networks, and the identity of the species with which they interact in about half of the Networks. Expand
The Geographic Mosaic of Coevolution
TLDR
Picking up where his influential The Coevolutionary Process left off, John N. Thompson synthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology.

Global change and species interactions in terrestrial ecosystems.
TLDR
It is concluded that in order to reliably predict the effects of GEC on community and ecosystem processes, the greatest single challenge will be to determine how biotic and abiotic context alters the direction and magnitude of G EC effects on biotic interactions. Expand
Diffuse coevolution within complex communities
TLDR
The working model for interpreting revolutionary interactions has itself evolved over the past 10 yr, and no appropriate metaphor has emerged that succinctly describes diffuse coevolution, and conveys the notion of evolutionary changes rippling out in many directions following changes in a component species. Expand
Trait-mediated indirect interactions : ecological and evolutionary perspectives
TLDR
This work focuses on the role of trait mediated indirect interactions in the study of biodiversity and ecosystem functioning in response to climate change, phenology, and the nature of consumer-resource interactions. Expand
Diversification through multitrait evolution in a coevolving interaction
TLDR
Experimental studies of the incompletely obligate interactions between woodland star plants and their pollinating floral parasites in the moth genus Greya (Prodoxidae) show that, as these lineages have diversified, the moths and plants have evolved in ways that maintain effective oviposition and pollination.
