Abstract Detecting environmental DNA (eDNA) of numerous organisms from the same samples has been revolutionized by metabarcoding. However, utilizing vast amounts data generated metabarcoding to predict occupancy probabilities for co‐occurring species is currently rare. Here, we demonstrate how can be used advance community ecology research through a case study using replicate stream water and Bayesian models test hypotheses eDNA occurrence native fish (brook trout, Salvelinus fontinalis ), its major ectoparasite (gill lice, Salmincola edwardsii an introduced potential competitor (brown Salmo trutta ). Gill lice was positively associated with brook trout biomass determined via electrofishing conducted near sampling sites, suggesting gill dependent on host density. Leveraging site‐specific molecular operational taxonomic units identified metabarcoding, often predicted richness aquatic insect orders commonly feed on, which are also quality indicators. Thus, high‐quality habitats that environmentally sensitive salmonids their primary prey rely may promote higher rates, further facilitating spread parasites. An increasing amount community‐level being global efforts, suggest our framework could broadly implemented enhance understanding factors impacting distributions species, reveal new ecological phenomena, support management conservation efforts.

Freshwater ecosystems are among the most severely affected environments by species loss caused climate change and intense anthropogenic pressure. To preserve biodiversity, biomonitoring plays a key role providing reliable data on biological diversity ecological status. Environmental DNA (eDNA) metabarcoding has emerged as powerful non-invasive alternative to traditional morphology-based sampling identification methods. This study represents first application of eDNA analysis assess invertebrate communities in three Sicilian Lakes: Poma, Piana degli Albanesi Scanzano. Water samples were collected at two points each lake after filtration with nitrocellulose membranes, was extracted performed. A total 27 identified, belonging Phyla Annelida, Arthropoda Rotifera. Notably, revealed presence alien (Daphnia parvula Acanthocyclops americanus), dangerous associated transmission viral diseases (Culex pipiens), potential new records for Sicily (Stylaria lacustris, Platypalpus exilis, Pammene aurana, Limnephilus rhombicus). These results provide preliminary snapshot biodiversity these sites, demonstrating how complement, but not replace, methods, contributing assessment ecosystem

Hazards associated with highly dangerous pollutants/contaminants in water, air, and land resources, as well food, are serious threats to public health the environment. Thus, it is imperative detect or decontaminate, risk-control strategies, possible harmful substances sensitively efficiently. In this context, due their capacity be specifically designed for various types of hazardous compounds, synthesis use molecularly imprinted polymers (MIPs) have become widespread. By molecular imprinting, affinity sites complementary shape, size, functionality can created any template molecule. MIPs' unique functions response external factors attracted researchers develop a broad range MIP-based sensors increased sensitivity, specificity, selectivity recognition element toward target compounds. Therefore, paper comprehensively reviews very recent progress MIPs smart polymer applications sensing decontamination compounds (e.g., drugs, explosives, biological chemical agents) fields from 2020 2024, providing rapid tool investigating latest research status.
