Biodiversity accumulates hierarchically by means of ecological and evolutionary processes feedbacks. Within communities drift, dispersal, speciation, selection operate simultaneously to shape patterns biodiversity. Reconciling the relative importance these is hindered current models inference methods, which tend focus on a subset their resulting predictions. Here we introduce massive ecoevolutionary synthesis simulations (MESS), unified mechanistic model community assembly, rooted in classic...
Important groups of mutualistic species are threatened worldwide, and identifying factors that make them more or less fragile in the face disturbance is becoming increasingly critical. Although much research has focused on ecological favor stability communities rich mutualists, been devoted to understanding role played by historical contemporary evolution. Here we develop mathematical models computer simulations coevolving allow us explore importance coevolution stabilizing against...
Abstract Ecologists often use dispersion metrics and statistical hypothesis testing to infer processes of community formation such as environmental filtering, competitive exclusion, neutral species assembly. These have limited power in inferring assembly models because they rely on often‐violated assumptions. Here, we adapt a model phenotypic similarity repulsion simulate the process via filtering all while parameterizing strength respective ecological processes. We then random forests...
Empirical evidence suggests that coevolutionary arms races between flowering plants and their pollinators can occur in wild populations. In extreme cases, trait escalation may result evolutionary switching from mutualism to parasitism. However, theoretical approaches studying coevolution typically assume fixed types of ecological interactions ignore the evolution absolute fitness. Here, we introduce a novel approach track fitness as framework determine when escalatory results switch We apply...
AbstractPrevious host-parasite coevolutionary theory has focused on understanding the determinants of local adaptation using spatially discrete models. However, these studies fall short describing patterns across spatial scales. In contrast, empirical work demonstrates that depend scale at which they are measured. Here, we propose a mathematical model coevolution in continuous space naturally leads to scale-dependent definition adaptation. agreement with research, find vary some cases, not...
Exaggerated traits involved in species interactions have long captivated the imagination of evolutionary biologists and inspired durable metaphor coevolutionary arms race. Despite decades research, however, we only a handful examples where reciprocal change has been rigorously established as cause trait exaggeration. Support for mechanism remains elusive because lack generally applicable tools quantifying intensity selection. Here develop an approximate Bayesian computation (ABC) approach...
Abstract The role of host-associated microbiomes in shaping host fitness is becoming increasingly recognized, and may have important evolutionary consequences. degree to which contribute evolution depends on how they are inherited. To understand the conditions under mediated by microbiome inheritance, we introduce a simple mathematical model. Our model tracks quantitative trait that genotype microbiome. Unlike genotype, several routes transmission, including social contact environmental...
Abstract Biodiversity accumulates hierarchically by means of ecological and evolutionary processes feedbacks. Reconciling the relative importance these is hindered current theory, which tends to focus on a single spatial, temporal or taxonomic scale. We introduce mechanistic model community assembly, rooted in classic island biogeography makes temporally explicit joint predictions across three biodiversity data axes: i) species richness abundances; ii) population genetic diversities; iii)...
All plants and animals are host to a community of microorganisms, their microbiomes, that have crucial influences on the life history performance hosts. Despite importance such host-microbiome relationships, relatively little is known about role microbiomes play in mediating evolution as well entire host-microbe assemblages. This knowledge gap partly due lack theoretical frameworks generate testable predictions evolutionary dynamics systems. In this Perspective, we argue foundation for...
Multicellular organisms host a rich assemblage of associated microorganisms, collectively known as their “microbiomes”. Microbiomes have the capacity to influence hosts’ fitnesses, but conditions under which such influences contribute evolution are not clear. This is due in part lack comprehensive theoretical framework for describing combined effects and microbes on phenotypic variation. Here we begin address this gap by extending foundations quantitative genetic theory include...
Abstract Although the evolutionary response to random genetic drift is classically modelled as a sampling process for populations with fixed abundance, abundances of in wild fluctuate over time. Furthermore, since exhibit demographic stochasticity, it reasonable consider stochasticity and its relation drift. Here we close this gap context quantitative genetics by deriving dynamics distribution character abundance biological population from stochastic partial differential equation driven...
