Sexual Selection on Non‐Ornamental Traits Is Underpinned by Evidence of Genetic Constraints on Sex‐Biased Expression in Dusky Pipefish

Molecular Ecology, EarlyView.
ABSTRACT Species lacking distinct secondary sex characteristics, such as differences in size or morphology, are often thought to experience lower levels of sex‐specific selection in comparison to highly sexually dimorphic organisms. However, monomorphism in classic visible traits could be a result of genetic or physiological constraints that prevent ...

3D Genome Constrains Breakpoints of Inversions That Can Act as Barriers to Gene Flow in the Stickleback

Molecular Ecology, EarlyView.
ABSTRACT DNA within the nucleus is organised into a well‐regulated three‐dimensional (3D) structure. However, how such 3D genome structures influence speciation processes remains largely elusive. Recent studies have shown that 3D genome structures influence mutation rates, including the occurrence of chromosomal rearrangement.

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids

Molecular Ecology, EarlyView.
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

Phylogenomics and revised classification of Lymexyloidea and Tenebrionoidea (Coleoptera: Polyphaga: Cucujiformia)

Systematic Entomology, EarlyView.
Using a large‐scale phylogenomic dataset, we provide the robustly supported phylogeny of the wider Tenebrionoid clade, with Lymexyloidea sister to the mordelloid clade (Mordellidae and Ripiphoridae) + remaining Tenebrionoidea. Lymexyloidea contained two newly circumscribed families, each of them with two subfamilies, and both Mordellidae and ...
