Summary: Manumycin A (MA) is a natural antibiotic with pleiotropic anticancer effects. This study found that the anticancer effects of MA may be counteracted by the mechanism related to heat shock proteins (HSPs) belonging to the HSPA (HSP70) family. Inhibition of HSPA-mediated adaptive mechanisms may improve the anticancer effect of MA.

Summary: The study conducted a systematic identification and functional analysis of HSP70s in turbot, revealing their essential roles in adapting to various environmental stresses. The research identified 16 HSP70 genes distributed on nine chromosomes in turbot and provided valuable insights into their evolution, classification, and functional diversity. Expression analysis showed significant up- or downregulation of HSP70 genes under different stress conditions, with three genes (hspa1a, hspa1b, and hspa5) responding to all induced stresses, indicating their involvement in anti-stress mechanisms. These findings contribute to understanding the biological function of HSP70s in turbot and the development of stress-resistant strains in aquaculture.

Summary: The study confirmed heterosis in thermal tolerance of interspecific hybrid abalone (SD) through Arrhenius break temperatures (ABT) of cardiac performance. RNA-Sequencing revealed significantly diverged alternative splicing events in response to heat stress in three abalone species, with SD showing the highest number. The enrichment analysis of KEGG pathways suggested that genes involved in protein processing in the endoplasmic reticulum, mitophagy, and NF-kappa B signaling pathway may play a crucial role in the thermal resistance of hybrid abalone.

Summary: The Pacific abalone is an economically important cold-water shellfish. High temperature negatively affects the survival of Pacific abalone, particularly in the south of China. A study on the molecular regulatory mechanisms of thermal stress response in Pacific abalone revealed that thermal stress leads to differential gene expression, particularly in genes related to protein folding, antigen processing, and immune defense. These findings contribute to a deeper understanding of heat stress regulation in Pacific abalone and provide basic data for breeding heat-resistant abalone.

Summary: Salmonid aquaculture has expanded globally in recent decades, with changes in cage technologies and locations. This study used satellite images to analyze the changes in cage size, location, and proximity to neighboring farms. The results showed that cage diameters have increased, leading to larger farms, while the distance to neighboring farms varied across regions. These changes have environmental and production consequences, emphasizing the importance of analyzing and improving management practices in salmon farming.

Summary: The Southern Ocean is facing unprecedented environmental risks and consequences from climate change. The response of the benthic fauna, which evolved in isolation, to future changes remains uncertain. Understanding the persistence of benthic fauna through past glacial-interglacial cycles provides valuable insights for future predictions. Currently, preserving genetic diversity and connectivity between populations is crucial for species to adapt.

Summary: Genomic studies have revealed extensive hidden diversity in reef-building corals, which is highly underestimated in terms of evolutionary and ecological relevance. Additionally, symbiotic algae within coral host species can provide adaptive responses to environmental stress and may contribute to coral genetic variation. This study examines the genetic variation of Acropora tenuis coral host and its associated symbiotic algae across the Great Barrier Reef. The results demonstrate three distinct genetic clusters of coral hosts, associated with latitude and inshore-offshore reef position, while symbiotic algae diversity is influenced by reef location relative to shore.

Summary: Antimicrobial peptides (AMPs) are short polypeptides that effectively target microorganisms, viruses, and cancer cells. Machine learning plays an important role in AMP discovery and prediction due to their low resistance selection. The impact of negative data sampling on model performance was investigated, with the finding that similar training and benchmark data sets positively affect model performance. However, existing benchmark analyses for AMP prediction models are biased and the most accurate model remains unknown.

Summary: Climate change poses a threat to coral reef survival through bleaching and mortality. Understanding the long-term effects of rapid climate change can be achieved by studying how coral populations respond to past climate shifts. In this study, genetic analysis of Acropora digitifera populations in northwestern Australia revealed distinct populations with rapid divergence since the last glacial maximum. The presence of selective sweeps in these populations suggests that host genes play a major role in adaptation. The photosymbiont communities, on the other hand, remained undifferentiated, indicating that acquisition of novel symbionts is not the primary driver of adaptation in this species.

Summary: Understanding the drivers of evolutionary innovation is crucial for understanding how evolutionary processes unfold. This study examined the Southern Ocean brittle stars and found that the species Ophionotus victoriae and O. hexactis are closely related with interspecific gene flow. Different refugia were identified for each species during the late Pleistocene, and gene flow was observed between different oceanic currents and local oceanographic regimes. A strong association was detected between outlier loci and salinity in O. hexactis, suggesting adaptation related to evolutionary innovations. These findings provide valuable insights into the drivers of innovation in the Southern Ocean fauna.

Summary: This study sampled octopods from commercial fisheries in southeast Australia to identify species, examine phylogeographic relationships, genetic structure within populations, and look for adaptive genetic variation. The study identified two octopus species, 'Octopus berrima' and 'Octopus pallidus', and found genetic and morphological differences among populations of both species. These findings provide important information for conservation and management decisions regarding octopod fisheries in southeast Australia.
