Summary: The acute effects of phloretin on metabolic pathways involved in glycemia maintenance were evaluated in this study. Phloretin inhibited gluconeogenesis, stimulated glycogenolysis and glycolysis, and altered oxygen consumption. It also disrupted mitochondrial bioenergetics and decreased enzyme activity. The findings suggest that caution should be exercised when using phloretin as a therapeutic agent, particularly in long-term and high-dose treatments.

Summary: This study evaluated the biodistribution and potency of transgene expression in mouse peripheral tissues in response to local and systemic administration of AAV8-LAP2 and AAV9-LAP2. The results showed that LAP2 promoter drives potent gene expression in the liver, kidney, and skeletal muscle, comparable to the EF1 alpha promoter. These findings suggest that constructs that include LAP2 may provide a means to deliver large therapeutically effective payloads in gene therapy protocols.

Summary: The island syndrome hypothesis predicts that island populations should differ from mainland populations, with individuals on islands being larger, less aggressive, more sociable, and investing more in their offspring. Using genome-wide SNP markers, this study found clear genomic differentiation between island and mainland populations, with moderate to high marker-based heritability estimates for traits thought to underlie the ISH. Further analysis identified 12 loci associated with differentiation between mainland and island populations, suggesting independent evolutionary trajectories and a genetic basis for the traits considered.

Summary: Phenotypic plasticity refers to the ability of one genotype to produce different phenotypes in different environments, and transgenerational plasticity allows the transmission of this environmentally-induced variation across generations. In this study, using a ciliate model-species, the researchers found that phenotypic traits related to dispersal are plastic and can be inherited over at least 35 generations. The fitness costs and benefits associated with these changes can also be passed on to further generations.

Summary: A chromosome-level reference genome for Greenland Halibut was successfully assembled using single-molecule sequencing and chromatin conformation capture sequencing data. The study revealed that Greenland Halibut possesses a male heterogametic XY system for sex determination, similar to other teleost fishes, and identified several candidate genes potentially involved in this process. Additionally, the study suggested a putative Y-autosomal fusion may be associated with reduced recombination during the early steps of sex chromosome evolution in flatfishes.

Summary: Under climate change, species without the ability to shift their range rely on genetic variation for adaptation. Genomic vulnerability studies often overlook hybridization as a source of adaptive variation. This study found that hybrid populations of rainbowfish showed reduced vulnerability to climate change compared to pure narrow endemics, highlighting the importance of hybrid populations and adaptive introgression in the evolutionary rescue of species with narrow environmental ranges.

Summary: Differences between sexes in trait fitness optima can contribute to genetic diversity through balancing selection, but detecting such conflicts is challenging. Recent studies have found that duplications on sexual chromosomes can create misleading signals of intralocus sexual conflicts. In this study, we investigated intralocus sexual conflicts in three-spined sticklebacks and found only two regions that showed potential conflicts and signals of balancing selection. These results suggest that most intralocus sexual conflicts are transient and do not drive long-term balancing selection.

Summary: In order to preserve the diversity of ecological and genetic factors in hotspots like tropical rainforests, it is important to understand the forces behind biodiversity. Through studying an Australian rainbowfish, Melanotaenia splendida splendida, across wet tropical regions, we found that environmental gradients and terrain structure strongly influence genetic and morphological variation. While neutral genetic population structure is mostly affected by limited gene flow, ecological variables are equally effective in explaining overall genetic variation and better at explaining body shape variation. The strongest environmental predictors are hydrological and thermal variables, which are correlated with heritable habitat-associated dimorphism in rainbowfish. Climate-associated genetic variation is significantly associated with morphology, supporting the heritability of shape variation. These results highlight the evolved functional differences among localities and emphasize the importance of hydroclimate in early stages of diversification. It is expected that tropical rainforest endemics will need to undergo significant evolutionary responses to mitigate fitness losses caused by climate change.

Summary: The ability to systematically detect parasitic infection, even without visible signs, is crucial for accurate conservation policies. In particular, the nematode Anguillicola crassus poses a potential threat to eel populations. The authors present a real-time PCR-based method to detect A. crassus infection in both final and intermediate hosts. By using this method, they were able to detect the DNA of A. crassus in both zooplankton and individual swim bladders. This method allows for early detection of A. crassus infection in nature, going beyond previous protocols.

Summary: In this study, researchers found that a overdominant supergene in seaweed flies strongly modulates male traits but only weakly affects female traits. Gas chromatography-electroantennographic detection revealed that females can sense male traits and there may be differential perception between genotypes. Gene expression analysis showed that candidate genes for trait biosynthesis primarily showed differential expression in males, while odorant detection genes were differentially expressed in both sexes but showed high levels of divergence between supergene haplotypes. The reduced recombination between supergene haplotypes may have led to rapid divergence in mate preferences and increasing linkage between male traits and overdominant loci, helping to maintain the polymorphism despite deleterious effects in homozygotes.
