Marine ecosystems are under escalating threats from myriad environmental stressors, necessitating a deeper understanding of their impact on biodiversity and the health of sentinel organisms. In this study, we carried out a spatiotemporal multi-omic analysis of liquid biopsies collected from mussels (Mytilus spp.) in marine ecosystems of a national park.

Article Synopsis
- - Oocysts of Toxoplasma gondii found in cat feces can contaminate coastal waters, where they attach to algae and accumulate in bivalves; studies were conducted in the Kerguelen and Galapagos archipelagos to assess this contamination.
- - In the Galapagos, high cat density (142 per km) led to 15.38% of oysters testing positive for T. gondii, while in Kerguelen, lower cat density (1-3 per km) resulted in a higher percentage (40.83%) of mussels testing positive.
- - The research suggests that oocysts can spread several kilometers from their source and that environmental factors, like currents and kelp forests
Article Synopsis
- Blue mussels are important indicators of ecosystem health due to their abundance and stable presence in polar coastal areas, which allows for monitoring biodiversity and species interactions.
- The study utilized liquid biopsy technology and Oxford Nanopore's portable sequencing platform to analyze the cell-free DNA in blue mussels, revealing significant biodiversity from various organisms in the marine ecosystem.
- The results highlight differences in nuclear and mitochondrial DNA distributions among sampling sites, demonstrating the ONT platform's effectiveness for fieldwork in conservation and resource management efforts in remote environments.
Establishing long-term microbiome-based monitoring programs is critical for managing and conserving wild fish populations in response to climate change. In most cases, these studies have been conducted on gut and, to a lesser extent, skin (mucus) microbiomes. Here, we exploited the concept of liquid biopsy to study the circulating bacterial microbiome of two Northern halibut species of economic and ecological importance.

Its concept is largely based on the detection of circulating cell-free DNA (ccfDNA) fragments that are mostly released as small fragments following cell death in various tissues. A small percentage of these fragments are from foreign (nonself) tissues or organisms.
