Sexual selection drives rapid phenotypic diversification of mating traits. However, we know
little about the causative genes underlying divergence in sexually selected traits. Here, we …

Sulawesi is a biodiversity hotspot for ricefishes (Adrianichthyidae), with many species
endemic to the central part of this island in single ancient lakes or lake systems. Frequent …

Recent genetic and genomic studies have revealed tremendous diversity in sex
chromosomes across diverse taxa. Closely related species with different sex chromosomes …

Transitions from no parental care to extensive care are costly and involve major changes in
life history, behavior, and morphology. Nevertheless, in Sulawesi ricefishes, pelvic brooding …

An increasing volume of empirical studies demonstrated that hybridization between distant
lineages may have promoted speciation in various taxa. However, the timing, extent and …

Sulawesi, an island located in a biogeographical transition zone between Indomalaya and
Australasia, is famous for its high levels of endemism. Ricefishes (family Adrianichthyidae) …

The application of demographic history modelling and inference to the study of divergence
between species has become a cornerstone of speciation genomics. Speciation histories …

Modes of reproduction in animals are diverse, with different modes having evolved
independently in multiple lineages across a variety of taxa. However, an understanding of …

Oryzias moramoensis, a new species of ricefish (Adrianichthyidae), is described from
Moramo Waterfall, Regency of Konawe Selatan, Southeast Sulawesi Province, Indonesia …

The DMY gene is deleted in all males of the Sanya population (SY-medaka) of the Hainan
medaka, Oryzias curvinotus, as recently reported by us. However, due to limited knowledge …
