Summary: This study presents a phylogenomic hypothesis on the evolutionary relationships within the killifish genus Kryptolebias through the use of mtDNA and genome-wide nuclear sites, revealing a new lineage hidden in a case of mito-nuclear discordance, and providing evidence of multiple events of ancestral introgression in the genus.

Summary: Different mating systems can impact hybridization between species, with self-incompatible species potentially outcompeting self-compatible ones. A study on mangrove killifish species with different mating systems found relatively high natural hybridization rates, mainly sired by the selfing species. This research sheds light on how contrasting mating systems may affect gene flow and the evolution of hybrid zones.

Summary: Kryptolebias marmoratus is a unique fish species with distinct phenotypes and behaviors. It provides insights into vertebrate sexual development and genetics as the only known self-fertile vertebrate. By optimizing husbandry techniques, including frequent egg collection and protease treatment, early cleavage-stage embryos can be maximized. This enables experimental analysis and targeted knockout of specific genes. These tools will contribute to our understanding of plasticity regulation.

Summary: In many species of Empis, Rhamphomyia and Hilara dance flies, females display ornaments prior to mating, which have evolved through sexual selection. This article reviews the mating diversity, including different types of ornaments and factors influencing sexual selection on each sex. The Empidinae subfamily within the dance flies provides unique opportunities to explore the causes and consequences of sexually selected ornament expression.

Summary: The study found that canine height and body mass in rhesus macaques are not related to dominance rank, but similarity in dominance rank affects the occurrence of aggressive interactions. Additionally, dominance rank predicts the likelihood of winning an agonistic interaction.

Summary: A new species of Brachypsectridae, Vetubrachypsectra huchengi, is described from Burmese amber, showing distinct differences from the previously reported V. burmitica, primarily in the pedicel-scape attachment and other morphological features. Sexual dimorphism is common in Brachypsectridae.

Summary: Sexual dichromatism was found in the genus Salamandrina, where males exhibit more conspicuous ventral colorations in the throat region, specifically featuring rounder, larger, and brighter gular white patches than females. Additionally, a new mating ritual behavior, throat hyperextension, was described in male S. perspicillata, which enhances the visibility of the dimorphic coloration in the gular region, presumably as a visual cue to attract females. The potential role of sexual dichromatism in sexual selection and the evolutionary history of the genus Salamandrina was discussed.

Summary: Sex roles describe sex differences in courtship, mate competition, social pair-bonds and parental care. A key challenge is to identify associations among the components and the drivers of sex roles. We found that proxies of sex roles showed extensive variation and lability, indicating independent evolution among sex role components. Climate and life history weakly associated with sex roles, while adult sex ratio was associated with sexual dimorphism, mating system and parental care.

Summary: Our study reveals that female seed beetles have higher phenoloxidase (PO) activity compared to males, and there are sex differences in the expression of genes in the prophenoloxidase activating cascade. Experimental evolution under enforced monogamy led to a decrease in female PO activity and an increase in tolerance to bacterial infection unrelated to mating. Additionally, female PO activity is correlated with male genitalia harmfulness across 12 species of seed beetles, suggesting that sexual conflict influences sexual dimorphisms in immunity in this group of insects.

Summary: This study evaluated the effects of maternal protein supplementation during mid-gestation on the offspring's feed intake parameters and found that protein supplementation can improve the performance and feed intake of the progeny. Additionally, protein restriction had different effects on the nutrient digestibility of female and male offspring.

Summary: In this study, a new genus of Kateretidae, Protokateretes, characterized by the exaggerated expansion of scape in males, was established. The species Eoceniretes antiquus was transferred to Protokateretes, and a new kateretid beetle with a large head, Protokateretes meg-acephalus, was described. This discovery highlights the morphological disparity of the small family in the Cretaceous period.

Summary: Phenomenological and behavioural studies have greatly advanced the study of natural selection. Selection on fore femur (sexual trait) and wing size (nonsexual trait) and shape varied considerably among seven species and continental populations. Strongest selection was found in species/populations with male-biased size dimorphism, implying mating advantages of large males.

Summary: Research shows that mating with a size-matched partner can increase fertilization success in Eastern Gray Treefrogs, and female call frequency preferences do not lead to the choice of a well-matched partner. Although mating appears to be random with respect to body size, the size distributions of males and females at the breeding site influence the pattern of size-assortative mating observed in nature.

Summary: By analyzing the genetic structure of Trichomycterus alternatus from 15 river drainages, it was found that the species is monophyletic and comprised of three main lineages. Dispersal via palaeorivers is an important process, but not enough to recover the most recent dispersive events. Integrating both palaeo-riverine configuration and localized river captures is crucial to understand the role of past geological and climatic events on the distribution of freshwater organisms.

Summary: Mangrove killifishes of the genus Kryptolebias, historically classified as rare due to their small size and cryptic nature, are found to be ubiquitously distributed across western Atlantic mangroves. The study reveals substantial genetic differences between clades, as well as further genetic structuring within clades in different regions, shedding light on the taxonomic status and distribution patterns of these self-fertilizing killifishes in the western Atlantic mangroves.

Summary: Hybridization plays a role in increasing genetic and epigenetic variation in natural hybrids of two genetically divergent fish species with different mating systems, as shown by the analysis of genetic backgrounds and methylation patterns. The study reveals that hybrids display predominantly intermediate methylation patterns, suggesting additive effects from hybridization. Additionally, a large number of differentially methylated cytosines between hybrids and parental species suggest the potential role of hybridization in increasing genetic and epigenetic variation.

Summary: This study presents a mathematical model proposing an alternative, adaptive route for the evolution of asexuality from previously sexual hybrids. The results show that when incompatibilities only affect the fusion of sperm and egg's genomes, the two traits that characterize asexuality can evolve separately, greatly facilitating the overall evolutionary route.

The distribution of H. pusarum was expanded to this basin, and a closely related species was recorded. The new species is distinguished by its unique characteristics such as tooth count, dental angle, pattern of spots, and abdominal plaques. The article also provides an identification key and geographic distribution maps.

Summary: Fishers' Ecological Knowledge was assessed to investigate the small-silvery herrings used in the traditional dish ginga corn tapioca, recognized as a cultural heritage in the Brazilian northeastern. Results showed that although ginga is known by different names elsewhere, it is only traded as such in the metropolitan area of Natal. Over- and under-differentiation were identified, with fishers recognizing ginga as five species but selling them as three main species.
