Summary: This study investigated the plasticity of behavioral and physiological responses of male moths to different sexual audiences before and during mating. Results showed that males adjusted their mating behaviors and spermatophore size based on the perceived risk of sperm competition, and reduced mating duration in the presence of females. However, these adjustments did not have an effect on reproductive performance.

Summary: Multiple mating by females can alter male selection through sperm competition. The most promiscuous males mated with less polyandrous females, resulting in lower levels of sperm competition. Females with more mating partners produced more offspring.

Summary: Male springbok mantises overcome the threat of female cannibalism by coercively wrestling females, increasing their chances of mating. However, this behavior may result in injuries and scar tissue formation in females, representing a potential negative pleiotropic side-effect.

Summary: This study investigates the correlation between sex allocation and reproductive behavior in hermaphroditic flatworms. The study finds that hypodermic insemination leads to a more female-biased sex allocation and is associated with selfing or biparental inbreeding. Additionally, a trade-off between male and female reproduction is observed, as well as a correlation between morphological indicators and sex allocation.

Summary: The black soldier fly is a highly valued insect in the feed industry. While research on its larval development and uses has been abundant, there is little knowledge about the adult biology. This lack of information hampers the industry's ability to mass produce the fly effectively for feed production. The aim of this review is to provide a foundation for future research, enabling comparable and optimized breeding systems.

Summary: Sexual conflict is a central paradigm in evolutionary biology. This article focuses on the seminal protein 'sex peptide' (SP) in Drosophila and challenges the widespread view that SP harms females while benefiting males. The authors argue that the existing view is oversimplified, narrow, and not supported by empirical evidence. They propose a more expanded view that SP has evolved to benefit females rather than harm them based on a comprehensive review of research findings.

Summary: Sperm allocation strategies in the externally fertilizing fish medaka were investigated. The study found that male medaka adjust the number of sperm released per mating according to their premating experience and cues from rival males.

Summary: Cryptic male mate choice refers to the differential allocation of resources by males to females during or after copulation. In the fruit fly Drosophila melanogaster, males mate longer and allocate more resources to larger females compared to smaller females. However, it is unclear if this increased investment in larger females has any impact on the males' subsequent matings.

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: This study investigates patterns of sperm use in Queensland fruit flies by observing the effects of multiple mating on paternity, shedding light on the species' reproductive biology and patterns of sperm usage. Comparison with other tephritid fruit flies provides insights into the reproductive biology of this species and implications for Sterile Insect Technique (SIT).

Summary: The study showed that prey availability and male-male competition can affect mating behavior in the Springbok mantis, with matings occurring more frequently and rapidly in the presence of both prey and competitors. This suggests that male mating decisions are influenced by competition and the risk of cannibalism.

Summary: This study examines the biogeography of the West Indies, highlighting the differences in research attention between terrestrial vertebrates and aquatic groups. The findings suggest that the species richness of livebearing fishes on the Greater Antilles is influenced not only by island size, but also by the presence of elevations. The study sheds light on the differing mechanisms driving speciation in aquatic versus terrestrial environments, suggesting that ecological opportunity may play a more significant role than island size in speciation.

Summary: Female preference is often related to male secondary sexual traits, but the exact mechanisms remain unclear. This study found that Limia perugiae females exhibited a preference for male body size, preferring smaller males despite males in this species having the most secondary sexual traits. Further research is needed to understand the impact of male secondary sexual traits on female preference.

Summary: Ecological gradients can drive adaptive phenotypic diversification, and the extent of local adaptation depends on the strength, temporal stability, and spatial dimensions of selective forces. Our study on a live-bearing fish in differential light regimes and toxicity levels revealed morphological and life history diversification. Despite exceeding the spatial dimensions of the gradients, the fish exhibited gradual changes in various traits along both gradients. The study also discovered remarkable temporal stability in two sampling periods.

Summary: Cannibalism is rare in the wild among fish species, with most populations and species showing no evidence of cannibalism. Juveniles are the primary victims, with a smaller portion being adult males. Females exhibit more cannibalism, likely due to their larger body size and greater energy requirements for reproduction. Intense resource competition drives cannibalistic behavior.

Summary: Understanding the origin and propagation of individual differences is essential in biology. This study demonstrates that indirect genetic effects (IGE) can influence the phenotypes of individuals who do not personally experience them. Genetically different social environments led to differences in aggression levels and these effects carried over to influence the behavior of naive individuals in new social groups.

Summary: In this study, two different approaches were used to investigate the presence of color polymorphism in the Cuban Limia fish. It was found that the frequency of black-spotted morphs was higher in brackish and saltwater environments, possibly due to higher predation pressure. The results suggest that habitat variation, particularly salinity levels, plays a key role in maintaining color polymorphism in this species.

Summary: Evaluating hybrid fitness provides insights into genetic differences between species or populations. We raised F1 hybrids of surface- and cave-ecotypes of Poecilia mexicana in a common-garden experiment to assess their survival, reproductive potential, and essential life-history traits. Compared to pure cave and surface fish, F1 hybrids had higher death rates and lower reproductive potential. We also observed sex-specific phenotype expression, with males expressing cave molly traits and females expressing surface molly traits. These findings suggest strong selection against hybrids in the cave molly system and a complex pattern of sex-specific dominance.

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.

Summary: Sexual reproduction is the primary mode of reproduction in eukaryotes, but some organisms have evolved into asexual reproduction. This review explores the mechanisms by which sperm-dependent asexuals can impact the evolution of coexisting sexual species and ecosystems, focusing on their impact on the gene pool, diversification rates, and spatial distribution of species. The review also proposes new research directions to enhance our understanding of genome evolution and biological interactions. Asexual species play important roles in ecosystems and their effects can last longer than traditionally believed.

Summary: Janzen's mountain passes hypothesis suggests different temperature gradients between low and high elevations in the tropics result in species evolving different thermal tolerances, but local-scale analysis of Limia fish populations did not support this hypothesis, indicating a need to consider other biotic factors in interpreting species distribution patterns.
