Adaptive evolution in response to varying environments, which leads to population divergence, is one of the most intriguing processes of speciation. However, its effectiveness amidst ongoing gene flow remains controversial. Our study challenges the controversy by analysing population genetic structure, degree of gene flow, and the level of genomic divergence between lineages of a tapeworm parasite (Ligula intestinalis), isolated from different species of fish hosts occurring in sympatry. The parasite, which must overcome the host's immunological defences for a successful infection, has a highly pathogenic impact. Utilising genome-wide Single Nucleotide Polymorphisms (SNPs) and transcriptome data, we investigated whether individual host species impose selection pressures on the parasite populations. Genetic clustering analyses revealed divergence between parasites infecting bream (Abramis brama) and those infecting roach (Rutilus rutilus), bleak (Alburnus alburnus), and rudd (Scardinius erythrophthalmus). Historical demography modelling suggested that the most plausible scenario for this divergence is isolation with continuous gene flow. Selection analysis identified 896 SNPs under selection, exhibiting lower to moderate nucleotide diversity and genetic divergence compared to neutral loci. Transcriptome profiling corroborated these results, revealing distinct gene expression profiles for the two parasite populations. An in-depth examination of the selected SNPs and differentially expressed genes revealed specific genes and their physiological functions, as candidates for the molecular mechanisms of immune evasion and, thus, for driving ecological speciation in the parasite. This study showcases the interplay between host specificity, population demography, and disruptive selection in ecological speciation. By dissecting the genomic factors at play, we gain a better understanding of the mechanisms facilitating population divergence in the presence of gene flow.

This study examined the hypothesis that the herbivory of Euborellia annulipes positively affects its biological traits, with variations based on the cultivated species of Brassica and the availability of essential food sources. The provision of plant material (leaf pieces) from the Brassica species pak choi cabbage, Portuguese cabbage, cabbage, and radish did not improve the biological performance of the earwig compared to a diet without plant material. Nevertheless, 66.0% and 43.3% of the second instar nymphs that solely consumed pak choi cabbage and Portuguese cabbage, respectively, completed their development successfully. Herbivory by E. annulipes on brassicas occurred both in the presence and absence of a diet, although it was significantly more pronounced when no other food sources were available. Among the four Brassica species studied, pak choi cabbage exhibited the highest feeding frequency and consumption rate. However, pak choi cabbage grown under controlled conditions and exposed to multiple releases of earwigs showed no reduction in productivity.
