Despite the fact that parasites are highly specialized with respect to their hosts, empirical evidence demonstrates host switching rather than co-speciation is dominant factor influencing diversification of host-parasite associations. Ecological fitting in sloppy fitness space has been proposed as a mechanism allowing ecological specialists host-switch readily. That proposal tested herein using an individual-based model switching. The considers parasite species exposed multiple resources....
Butterflies are a diverse and charismatic insect group that thought to have evolved with plants dispersed throughout the world in response key geological events. However, these hypotheses not been extensively tested because comprehensive phylogenetic framework datasets for butterfly larval hosts global distributions lacking. We sequenced 391 genes from nearly 2,300 species, sampled 90 countries 28 specimen collections, reconstruct new phylogenomic tree of butterflies representing 92% all...
Because host-parasite interactions are so ubiquitous, it is of primary interest for ecologists to understand the factors that generate, maintain and constrain these associations. Phylogenetic comparative studies have found abundant evidence host-switching relatively unrelated hosts, sometimes related diversification events, in a variety systems. For Monogenoidea (Platyhelminthes) parasites, has been suggested co-speciation model alone cannot explain host occurrences, hence and/or...
Explaining the exceptional diversity of herbivorous insects is an old problem in evolutionary ecology. Here we focus on two prominent hypothesised drivers their diversification, radiations after major host switch or variability use due to continuous probing new hosts. Unfortunately, current methods cannot distinguish between these hypotheses, causing controversy literature. present approach combining network and phylogenetic analyses, which directly quantifies support for opposing...
Intimate ecological interactions, such as those between parasites and their hosts, may persist over long time spans, coupling the evolutionary histories of lineages involved. Most methods that reconstruct coevolutionary history interactions make simplifying assumption have a single host. Many also focus on congruence host parasite phylogenies, using cospeciation null model. However, there is an increasing body evidence suggesting ranges are more complex: often include than one evolve via...
Myriad branches in the tree of life are intertwined through ecological relationships. Biologists have long hypothesized that intimate symbioses between lineages can influence diversification patterns to extent it leaves a topological imprint on phylogenetic trees interacting clades. Over past few decades, cophylogenetic methods development has provided toolkit for identifying such histories codiversification, yet is often difficult determine which tools best suit task at hand. In this...
Abstract The study of herbivorous insects underpins much the theory that concerns evolution species interactions. In particular, Pieridae butterflies and their host plants have served as a model system for studying evolutionary arms races. To learn more about coevolution these two clades, we reconstructed ancestral ecological networks using stochastic mappings were generated by phylogenetic host‐repertoire evolution. We then measured if, when, how ecologically important structural features...
1. One of the main challenges faced by ecologists today is to understand and predict how species interactions will respond current environmental change. It likely that these changes have a stronger effect on phylogenetic lineages depend intimate specialised ecological interactions, such as most herbivorous insects. 2. In this review, we highlight aspects consider are fundamental for understanding change over time. We start reviewing terminology conclude commonly used terms undesired...
Colonization of novel hosts is thought to play an important role in parasite diversification, yet little consensus has been achieved about the macroevolutionary consequences changes host use. Here, we offer a mechanistic basis for origins diversity by simulating lineages evolved silico. We describe individual‐based model which (i) parasites undergo sexual reproduction limited genetic proximity, (ii) are uniformly distributed along one‐dimensional resource gradient, and (iii) use determined...
Abstract Theory on plasticity driving speciation, as applied to insect–plant interactions (the oscillation hypothesis), predicts more species in clades with higher diversity of host use, all else being equal. Previous support comes mainly from specialized herbivores such butterflies, and theory suggests that there may be an upper range limit where no longer promotes diversification. The tussock moths (Erebidae: Lymantriinae) are known for extreme levels polyphagy. We demonstrate this system...
In this study, the competing hypotheses of single vs. double colonisation events for freshwater Pachyurinae (Sciaenidae) in South America is tested and historical biogeography expansion clade within continent reconstructed based on phylogenetic analysis. Parsimony Bayesian inference ( BI ) 19 marine species assigned to Sciaenidae, Haemulidae Polypteridae were determined partial sequences mitochondrial 16S cytochrome b genes fragments nuclear Tmo‐4C4 rhodopsin genes.

Abstract Butterflies are a diverse and charismatic insect group that thought to have diversified via coevolution with plants in response dispersals following key geological events. These hypotheses been poorly tested at the macroevolutionary scale because comprehensive phylogenetic framework datasets on global distributions larval hosts of butterflies lacking. We sequenced 391 genes from nearly 2,000 butterfly species construct new, phylogenomic tree representing 92% all genera aggregated...
Abstract Gut microbes play important roles for their hosts. Previous studies suggest that host-microbial systems can form long-term associations over evolutionary time and the dynamic changes of intestinal system may represent major driving forces contribute to insect dietary diversification speciation. Our study includes a set six closely related leaf beetle species ( Galerucella spp.) our aims separate host phylogeny ecology in determining gut microbial community identify eventual...
Abstract Evidence that species interactions can affect macroevolutionary dynamics of trait and diversification is scarce. Mutualistic Müllerian mimicry a compelling example ecological has been shown to drive evolutionary convergence, Here, we test how mutualistic shapes patterns in the Ithomiini butterflies. We show age color primary determinant richness within rings but not phylogenetic diversity. find pervasive signal associated polymorphic species. Only small set high identify saturation...
Abstract Evolutionary changes in geographic distribution and larval host plants may promote the rapid diversification of montane insects, but this scenario has been rarely investigated. We studied radiation butterfly genus Colias, which diversified mountain ecosystems Eurasia, Africa, Americas. Based on a data set 150 nuclear protein-coding genetic loci mitochondrial genomes, we constructed time-calibrated phylogenetic tree Colias species with broad taxon sampling. then inferred their...
Abstract The astonishing diversity of plants and insects their entangled interactions are cornerstones in terrestrial ecosystems. Co‐occurring with species is the plant secondary metabolites (PSMs). So far, estimated number more than 200 000 compounds, which not directly involved growth development but play important roles helping handle environment including mediation plant–insect interactions. Here, we use volatile organic compounds (VOCs), a key olfactory communication channel that...
Artificial substrates in and near ports marinas commonly have many non-indigenous species are the first stepping stone for establishment of bioinvasors. Substrate movement influences fouling communities so understanding how assemblages related to specific substrate conditions is crucial as a management tool. Here we describe assemblage community after six months development on granite plates Paranaguá Bay. Species richness was similar two treatments, with 12 floating (constant depth) 15...
Abstract In this study, we investigated whether patterns of gene expression in larvae feeding on different plants can explain important aspects the evolution insect–plant associations, such as phylogenetic conservatism host use and re-colonization ancestral hosts that have been lost from repertoire. To end, performed a phylogenetically informed study comparing transcriptomes 4 nymphalid butterfly species Polygonia closely related genus Nymphalis. Larvae were reared Urtica dioica, Salix spp.,...
