Molecular Ecology, Volume 34, Issue 20, October 2025.ABSTRACT The molecular basis of sex determination (SD), while being extensively studied in model organisms, remains poorly understood in many animal groups. Bivalves, a diverse class of molluscs with a variety of reproductive modes, represent an ideal yet challenging clade for investigating SD and the evolution of sexual systems.

Highly Contiguous Genome Assemblies of 15 Drosophila Species Generated Using Nanopore Sequencing
G3: Genes, Genomes, Genetics, 2018 The Drosophila genus is a unique group containing a wide range of species that occupy diverse ecosystems. In addition to the most widely studied species, Drosophila melanogaster, many other members in this genus also possess a well-developed set of ...

Population Ecology, Volume 67, Issue 3, Page 191-207, July 2025.A scenario in which divergent selection derived from ecological environments leads to genital divergence through body size evolution. Abstract To explore how ecological diversity contributes to the establishment of ecologically similar species with sexual divergence, this review focuses on body size—an environmentally influenced trait that determines ...

BMC Genomics, 2003 Background Non-coding DNA represents a high proportion of all metazoan genomes. Although an undetermined fraction of this DNA may be considered devoid of any function, it also contains important information residing in specific cis-regulatory sequences ...

Multiple Mating and Female Fitness in Drosophila pseudoobscura [PDF]
Evolution, 1983 All biological processes directly related to reproduction play a role in determining fitness. Collectively, these processes determine the fertility component of fitness, where fertility is defined in its broadest sense. The importance of fertility differences to selection has been demonstrated repeatedly over the past 15 years, particularly in studies ...

Ecology and Evolution, Volume 15, Issue 3, March 2025.The study expands genomic resources for Drosophila and Scaptodrosophila species by using mitochondrial genomes. Phylogenetic analyses revealed well‐supported evolutionary relationships, with Scaptodrosophila forming a distinct lineage and several Drosophila subgroups exhibiting monophyly, though discrepancies were found in the placement of the suzukii ...

Long‐Term Maintenance of Complex Chromosomal Inversion Polymorphism in Drosophila mediopunctata
Ecology and Evolution, Volume 14, Issue 10, October 2024.It has become increasingly clear that natural selection favors haplotypes that draw functionally related genes together, often targeting mechanisms that control recombination rates. In this paper, we show that the long‐term maintenance of linkage disequilibrium between linked non‐overlapping chromosomal inversions in a Drosophila species may arise from

Time in a bottle: the evolutionary fate of species discrimination in sibling Drosophila species. [PDF]
PLoS ONE, 2012 Disadvantageous hybridization favors the evolution of prezygotic isolating behaviors, generating a geographic pattern of interspecific mate discrimination where members of different species drawn from sympatric populations exhibit stronger preference for

Ecology and Evolution, Volume 14, Issue 7, July 2024.In theory, having sex chromosomes is advantageous to reduce sexual conflict. Our analyses revealed that many genes have acquired the sex‐biased expression on the neo‐sex chromosomes particularly at the larval stage. Our study indicates that cryptic sexual conflict at the preadult stages cannot be ignored, and some of these conflicts may have been ...
