Summary: Almost all eukaryotes exhibit sexual reproduction, but the systems by which sex is determined vary greatly even among closely related species. While animals typically have males and females, eukaryotic microbes can have thousands of different mating types. Some species have also developed alternative modes of reproduction, with occasional facultative sexual reproduction. In this review, we summarize the different modes of sex determination and reproductive variants across the eukaryotic tree of life, with a focus on the unique opportunities provided by eukaryotic microbes. We propose that studying the variations in sexual reproduction modes can serve as a foundation to understand the evolution of sex.

Summary: This study investigated the maturation of the ovarian portion of the ovotestes, mating viability, and embryonic development in Lysmata ankeri, an ornamental species widely exploited by marine aquariums. The research found that mating success was higher in hermaphrodite pairs compared to pairs with a male shrimp. Additionally, L. ankeri showed continuous reproduction with the production of viable larvae with a low yolk reserve.

Summary: This study investigated the mating behavior characteristics and their relationship with reproductive performance in Sichuan white geese, Zhedong white geese, and Hungarian geese. The results showed that the mating behaviors varied among different breeds mainly in terms of time preference and successful copulation frequency. This study provides valuable insights for the reproductive management of domesticated geese.

Summary: The genetic regulation of Colletotrichum sexual reproduction deviate from the typical paradigm of Ascomycota and is not well understood. This study characterized the sexual behaviors of different strain types and identified molecular mechanisms underlying the process. The presence of both cross-fertilized and self-fertilized perithecia within the mating line was confirmed, shedding light on the unique sexual enhancement in Colletotrichum fungi.

Summary: The population structure and reproductive pattern of the hermit crab Clibanarius rhabdodactylus were studied in the rocky intertidal region of Veraval, Gujarat, India. Monthly sampling was conducted from March 2021 to February 2022, and the individuals were classified into male, non-ovigerous female, and ovigerous female categories. The study revealed sexual dimorphism, with males being larger than females, and a female-biased overall sex ratio. Ovigerous females were present throughout the year, with peak reproductive activity in January to June and September to October, showing a continuous reproductive pattern.

Summary: This study compares the genetic differences between heterothallic and unisexual species in the Huntiella genus and finds significant differences in the genes governing sexual traits. Unisexual species do not rely on a mating partner recognition system like heterothallic species do. These results not only provide clues to understanding the mechanism of unisexual reproduction in the Huntiella genus, but also offer broader insights into the sexual reproduction and mating strategies of fungi.

Summary: Fungi in the genus Malassezia, which are commonly found on the skin of humans and other warm-blooded animals, have been linked to skin diseases and systemic disorders. Analysis of Malassezia genomes suggests that their ability to adapt to the skin microenvironment is directly influenced by their genetic makeup. Despite the absence of observed sexual reproduction, the presence of mating/meiotic genes suggests a potential for sexual reproduction in Malassezia. The arrangement of mating type loci in Malassezia has been found to be different from other basidiomycetes, indicating an ancestral state of the genus.

Summary: Sexual reproduction increases genetic diversity but also has associated costs such as exposure to parasites and reduced life span. In this study, we investigated the impact of mating status on the longevity of adult black soldier flies. We found that females had shorter longevity than males, but mating increased female longevity while decreasing male longevity. Additionally, we examined the abdominal 'window' of the flies and found that window fullness decreased with age in unmated males, while unmated females maintained high fullness until older ages. Mated females mostly had full windows, while mated males had mostly empty windows.

Summary: The study found that male age has a significant impact on the re-mating incidence in female Aedes aegypti mates, with younger males having a competitive advantage. Regardless of the age of the initial mate, females displayed first male precedence. Additionally, younger males had more sperm at the time of mating, although both age groups transferred a similar number of sperm to their mates.

Summary: Amphipods play a crucial role in freshwater ecosystems and are widely used as model organisms in environmental sciences and ecotoxicology. This study successfully optimized breeding conditions for the amphipod Gammarus fossarum, increasing survival, reproduction, and multi-generation breeding. The supplementation of protein-rich food and provision of shelters significantly improved survival rate. Despite longer generation times and higher maintenance efforts compared to other model organisms, the direct ecological relevance and comparability of results may justify the use of G. fossarum in future research.

Summary: This study reveals the complexity of sexual regulation in Colletotrichum fungi, as the importance of pheromone receptors and their cognate pheromones varies. The gene-deletion mutants of C. fructicola showed that PRE1 and PRE2 genes coordinate the mating of this species by recognizing novel signal molecules, while PPG1 and PPG2 genes have no effect on sexual compatibility and development.

Summary: The study of newly discovered Exucarcinus gonzagai fossils revealed three distinct ontogenetic stages, with carapaces becoming wider and spinier as they develop. Preservation of anatomical structures is influenced by fossilization process, impacting systematic and phylogenetic decisions within the group. It is important to consider these variations in order to avoid inaccurate phylogenetic decisions.

Summary: Researchers have observed a modular pattern in the relationship between hermit crabs and gastropod shells, where the network can be divided into compartments with species interacting more within their own compartment. Different morphometric traits in hermit crabs influence their specialization levels, as hermit crabs of different sizes may require different types of shells for optimal interaction.

Summary: This study assesses the diversity of rocky infralittoral decapods Brachyura and Anomura from the Marine State Park of Laje de Santos in Brazil. The study utilizes sampling methods including artificial refuge substrate (ARS) and SCUBA diving, and identifies a total of 32 species, 22 genera, and 11 families. The results suggest that the combination of sampling methodologies provides a more accurate assessment of diversity compared to individual methods.

Summary: This study describes the fatty acid composition of three commercially important shrimp species from a region with large mangrove forests in Brazil. The unique fatty acid profiles of each species were influenced by their different life cycles, with significant differences observed in certain key fatty acids. Shrimps from this region are highlighted as essential sources of fatty acids in the trophic web and valuable for human health, particularly due to their polyunsaturated fatty acids EPA and DHA.

Summary: We investigated the trophic relationships of the endemic crustacean Aegla castro using stable isotopes. The results showed that Aegla castro occupies a lower trophic level and serves as an important link in the freshwater food chain. The isotopic signatures of Aegla castro varied according to the sampling locations, indicating the influence of environmental differences.

Summary: Thoe Bell, 1836 is a type of amphiamerican small spider crab with cryptic habits, which has rare records in the literature and carcinological collections. The taxonomy of the known species in the genus has been revised, and a phylogenetic reconstruction based on mitochondrial markers supports the monophyletic status of Thoe and suggests a radiation of the genus from the western Atlantic to the eastern Pacific.

Summary: The marine crab Xanthodius parvulus is commonly found in the Western Atlantic, specifically in the northeastern Brazilian coast. This study estimated the morphological sexual maturity of the species and found that females mature at 7.28 mm while males mature at 8.83 mm. It was also observed that females continue to grow their abdomen during maturity for reproductive success, while males copulate with different sized females based on their gonopod length.
