TL;DR: A significant negative correlation was found between rank and deviation of individual males from the overall mean syllable length, indicating stabilizing selection on this character, which may be involved in species recognition.

TL;DR: To study the evolution of this Pyrenean hybrid zone following postglacial secondary contact, a crossing programme was performed involving sequential mating of single females by males of both subspecies in both orders, revealing a number of significant departures from straightforward inheritance.

TL;DR: Functional annotation of the contigs containing outlier SNPs showed that they included shell matrix and muscle proteins, proteins involved in energetic metabolism, and reverse transcriptases that will be a promising route in the study of ecological speciation in L. saxatilis.

TL;DR: An approach that combines hybrid zone analysis with system‐specific simulations to identify loci inconsistent with neutral evolution is developed, in line with theory predicting a role for inversions in divergence and emphasizes that genomic regions contributing to divergence may not always be accessible with methods purely based on allele frequency differences.

TL;DR: Two polymerase chain reaction (PCR)‐based methods for distinguishing morphologically similar species based on amplification of a variable region of the 28S gene of ribosomal DNA are reported.
