Visual mate preference evolution during butterfly speciation is linked to neural processing genes
Nature Communications, 2020 The genetic mechanisms underlying mate choice decisions can inform our understanding of speciation. A study on Heliconius butterflies identifies 5 candidate genes that would allow sympatric species to evolve distinct preferences without altering their ...

Stridulations reveal cryptic speciation in neotropical sympatric ants. [PDF]
PLoS ONE, 2010 The taxonomic challenge posed by cryptic species underlines the importance of using multiple criteria in species delimitation. In the current paper we tested the use of acoustic analysis as a tool to assess the real diversity in a cryptic species complex

Ability of Current Phylogenetic Clustering to Detect Speciation History
Frontiers in Ecology and Evolution, 2021 Phylogenetic diversity aims to quantify the evolutionary relatedness among the species comprising a community, using the phylogenetic tree as the metric of the evolutionary relationships.

Reproductive isolation between two populations of Aglaoctenus lagotis , a funnel-web wolf spider [PDF]
, 2015 Aglaoctenus lagotis (Lycosidae: Sosippinae) is a spider that, in contrast to the predominant wandering habit of the family, constructs funnel webs.

Hybridization, Homogamy, and Sympatric Speciation [PDF]
Evolution, 1955 Mayr (1947) has presented a strong case against the hypothesis of sympatric speciation in the course of supporting the universal hypothesis of geographic (or at least microgeographic) speciation. In the summary (p. 286) of that paper he made the following statement: "It is unproven and unlikely that reproductive isolation can develop between contiguous

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]
, 2016 Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.

A simple model to study phylogeographies and speciation patterns in space
, 2012 In this working paper, we present a simple theoretical framework based on network theory to study how speciation, the process by which new species appear, shapes spatial patterns of diversity.

Formation, production and viability of oospores of Phytophthora infestans from potato and Solanum demissum in the Toluca Valley, central Mexico [PDF]
, 2001 Aspects of the ecology of oospores of Phytophthora infestans were studied in the highlands of central Mexico. From an investigation of a random sample of strains, it was found that isolates differed in their average capability to form oospores when ...

Sympatric Speciation by Sexual Selection: A Critical Reevaluation [PDF]
The American Naturalist, 2004 Several empirical studies put forward sexual selection as an important driving force of sympatric speciation. This idea agrees with recent models suggesting that speciation may proceed by means of divergent Fisherian runaway processes within a single population.
