Female and male song exhibit both parallel and divergent patterns of cultural evolution: a long-term study of song structure and diversity in tropical wrens
<p>Animal culture changes over time through processes that include drift, immigration, selection, and innovation. Cultural change has been particularly well-studied for animal vocalizations, especially for the vocalizations of male animals in the temperate zone. Here we examine cultural change in the vocalizations of tropical Rufous-and-white Wrens (<i>Thryophilus rufalbus</i>), quantifying temporal variation in song structure, song type diversity, and population-level distribution of song types in both males and females. We use data from 10 microsatellite loci to quantify patterns of immigration and neutral genetic differentiation over time, to investigate whether cultural diversity changes with rates of immigration. Based on 11 years of data, we show that the spectro-temporal features of several widely-used persistent song types maintain a relatively high level of consistency for both males and females, whereas the distribution and frequency of particular song types change over time for both sexes. Males and females exhibit comparable levels of cultural diversity (i.e. the diversity of song types across the population), although females exhibit greater rates of cultural change over time. We found that female changes in cultural diversity increased when immigration is high, whereas male cultural diversity did not change with immigration. Our study is the first long-term study to explore cultural evolution for both male and female birds and suggests that cultural patterns exhibit notable differences between the sexes.</p>
Data from: Genomic signatures of divergent selection and speciation patterns in a 'natural experiment', the young parallel radiations of Nicaraguan crater lake cichlid fishes
Divergent selection is the main driving force in sympatric ecological speciation and may also play a strong role in divergence between allopatric populations. Characterizing the genome-wide impact of divergent selection constitutes often a first step in the process of unraveling the genetic bases underlying adaptation and ecological speciation. The Midas cichlid fish (Amphilophus citrinellus) species complex in Nicaragua is a powerful system for studying evolutionary processes. Independent colonizations of isolated young crater lakes by Midas cichlid populations from the older and great lakes of Nicaragua resulted in the repeated evolution of adaptive radiations by intralacustrine sympatric speciation. In this study we performed genome scans on two repeated radiations of crater lake species and their great lake source populations (1030 polymorphic AFLPs, n ≈ 30 individuals per species). We detected regions under divergent selection (0.3 % in the crater lake Xiloá flock and 1.7 % in the older crater lake Apoyo radiation) that might be responsible for the sympatric diversification. We find no evidence that the same genomic regions have been involved across crater lake flocks. The data provide evidence, however, for some genetic parallelism (seven out of 51 crater lake to great lake outlier loci are shared; 13.7%) associated with the allopatric divergence of both crater lake flocks. Furthermore, our results suggest that the number of outlier loci involved in sympatric and allopatric divergence increases with time. A phylogeny based on our data clearly supports the monophyly of both crater lake species flocks and provides evidence for a parallel branching order with a primary divergence along the limnetic-benthic axis in both radiations.
