Abstract Chromosomal inversions can play an important role in divergence and reproductive isolation by building maintaining distinct allelic combinations between evolutionary lineages. Alternatively, they take the form of balanced polymorphisms that segregate within populations until one arrangement becomes fixed. Many questions remain about how inversion arise, are maintained over long term, ultimately, whether contribute to speciation. The long‐snouted seahorse ( Hippocampus guttulatus ) is genetically subdivided into geographic lineages marine‐lagoon ecotypes, with shared structural variation underlying lineage ecotype divergence. Here, we aim characterize variants reconstruct their history suspected formation. We generated a near chromosome‐level genome assembly described genome‐wide patterns diversity through analysis 112 whole‐genome sequences from Atlantic, Mediterranean, Black Sea populations. By also analysing linked‐read sequencing data, found evidence for two chromosomal were several megabases length showed contrasting allele frequency ecotypes across species range. reveal these represent ancient intraspecific polymorphisms, likely being divergent selection other pseudo‐overdominance. A possible selective coupling was further supported absence specific haplotype putative functional interaction reproduction. Lastly, detected gene flux eroding inverted alleles at varying levels inversions, impact on dynamics contribution

Seahorses, seadragons, pygmy pipehorses, and pipefishes (Syngnathidae, Syngnathiformes) are among the most recognizable groups of fishes because their derived morphology, unusual life history, worldwide distribution. Despite previous phylogenetic studies recent new species descriptions syngnathids, evolutionary relationships several major within this family remain unresolved.

Published: Dec. 9, 2022

In the highly derived syngnathid fishes (pipefishes, seadragons & seahorses), evolution of sex-role reversed brooding behavior culminated in seahorse lineage's male pregnancy, whose males feature a specialized brood pouch into which females deposit eggs during mating. Then, are intimately engulfed by placenta-like tissue that facilitates gas and nutrient exchange. As fathers immunologically tolerate allogenic embryos, it was suggested pregnancy co-evolved with specific immunological adaptations. Indeed, here we show amino-acid replacement tlx1 transcription factor is associated seahorses' asplenia (loss spleen, an organ central immune system), as confirmed CRISPR-Cas9 experiment using zebrafish. Comparative genomics across phylogeny revealed complexity system gene repertoire decreases parental care intensity increases. The synchronous immunogenetic alterations supports notion tolerance embryo.

The Aulostomidae family is recorded first time Peru. Of species, only belongs to Warm Temperate Southeastern Pacific biogeographic province, while other ten belong Tropical Eastern Pacific. Five these have their main populations in Indo-Pacific, being considered transpacific species.
