Summary: This study focused on mapping the quantitative trait locus (QTL) of resistance to A. flavus infection in the peanut variety J11. Six novel resistant QTLs were identified on chromosomes A05, A08, B01, B03, and B10, with phenotypic variances explained ranging from 5.03% to 10.87%. The combination of these QTLs significantly improved resistance to A. flavus infection, providing insights into the genetic basis of resistance and potential for further improvement in peanuts.

Summary: This study constructed two F-2 populations using the DM-resistant accession PI 442177 and mapped QTLs conferring DM resistance. A high-density genetic map was generated and a major QTL DM9.1 was consistently detected at different growth stages. QTL-seq analysis validated the presence of DM9.1 and a KASP marker co-segregating with DM9.1 was successfully developed, providing valuable information for DM-resistant gene cloning and melon DM-resistant breeding programs.

Summary: In this study, a mapping population of 96 individuals was generated through crossbreeding of two banana parents. A genetic linkage map was constructed using GBS technique, which consisted of 1015 SNP markers. Five QTLs associated with drought tolerance traits were identified on chromosomes 2, 5, and 8. This is the first report of using SNP markers to study drought tolerance traits in banana, and the findings will contribute to fine mapping and marker-assisted selection for drought related traits.

Summary: Through phylogenomic and clustering methods using RADseq, UCEs, and morphological data, this study revealed the impact of introgressive hybridization on genomes and morphology within a species complex of jumping spiders. Geographic region was a better predictor of phylogenetic relatedness and genomic similarity among species than species or morph identity. Rapid radiation and frequent introgression have homogenized the genomes of species in this system, while selective pressures maintain distinct male morphologies.

Summary: The developmental mechanisms of genital divergence in ground beetles were studied by examining two closely related species using X-ray microcomputed tomography. It was found that while the morphogenesis of male and female genitalia at the pupal stage was qualitatively similar, species-specific genital parts developed at different rates and timings, leading to substantial interspecific differences in genital size mediated by different underlying mechanisms between the sexes.

Summary: This study characterized sexual dimorphism in populations of the false blister beetle Oedemera sexualis, finding significant variation in both body size and hindleg sizes among populations. It was observed that the degree of constrained growth of male hind femur widths differed among populations, with smaller mean values for sexual traits showing more limited sexual trait exaggeration within populations. Environmental constraints on exaggeration may be responsible for sexual trait diversification in O. sexualis.

Summary: The predator digger wasp Cerceris albofasciata showed prey size preference and natural selection on body sizes when hunting adult Cassidinae leaf beetles, preferring larger prey that could be carried into their nest but hunting smaller prey than their nest entrance size. This suggests that the benefits of large prey and the costs associated with nest expansion influence prey size preference in this predator-prey system.

Summary: Carabinae beetles, a group of flightless underground insects, are widely distributed on all continents except Antarctica. Through DNA analysis, researchers have found that Carabinae originated in the Americas and diversified into four tribes. The ancestral Carabinae had wings, but three of the tribes lost their wings and flight capability during evolution. The study also revealed a higher speciation rate of Carabinae in Eurasia.

Summary: This study focused on the spatial and temporal variation in carabid beetle communities and environmental factors across three mountains. It found significant temporal variation in beetle communities, which may be a response to local climate variations. Local-scale temporal surveys are important for predicting changes in communities over time.

Summary: Genital morphology can reveal rapid diversification among species, and species-specific divergence in genital morphology can lead to reproductive isolation and promote speciation. In this study, the researchers focused on closely related Ohomopterus ground beetle species to examine reproductive character displacement (RCD) and its underlying mechanisms. They found patterns of RCD in species-specific genital parts and suggested that reinforcement is the most plausible process underlying the observed RCD.

Summary: This study examined hypotheses for reproductive character displacement (RCD) in genital morphology, with a focus on the Templeton effect. The results showed no evidence for the predictions of the Templeton effect, as the interspecific mating costs varied among populations and the population-level fitness costs did not necessarily decrease during the process leading to RCD.

Summary: The evolution of exaggerated sexual traits is possible due to the relaxation of various constraints, including functional, genetic, and structural constraints. Functional constraints refer to reduced performance or increased survival costs of exaggerated traits. Genetic constraints hinder independent evolution and exaggeration of traits, while structural constraints require coordination of traits. A study on male genital morphology in ground beetles suggests that functional constraints are relaxed in species with exaggerated genitalia, genetic constraints have little effect, and structural constraints are strongest in species with the most exaggerated genitalia.

Summary: The Indian subcontinent has many terrestrial animal and plant species that are similar to those in Southeast Asia, with the study finding that Oryzias setnai is sister to other Adrianichthyids from eastern India and Southeast Asia. Divergence time estimates and ancestral area reconstructions suggest that this western Indian species diverged during the northward drift of the Indian subcontinent, indicating a dispersal 'out-of-India' and subsequent diversification in Southeast Asia. Geographical distributions of 'out-of-India' taxa may have significantly impacted the biodiversity of Eurasia.
