Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics

open access: yesMolecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of

Modelling Salmo trutta Complex Spatial Distribution in Central Italy: A Random Forest Approach Revealing Underrepresented Lowland Populations Based on Spatially‐Explicit Predictors

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Using freely available spatially explicit environmental‐bioclimatic predictors, in a Random Forest framework, we: (i) accurately modelled the spatial distribution of Salmo trutta complex in central Italy; (ii) revealed the suitability of naturally infrequent lowland watercourses where trout occurrence is only partly known; (iii) provided information on

Molecular Mechanisms, Endurance Athlete, and Synergistic Therapeutic Effects of Marine‐Derived Antioxidant Astaxanthin Supplementation and Exercise in Cancer, Metabolic Diseases, and Healthy Individuals

open access: yesFood Science &Nutrition, Volume 13, Issue 7, July 2025.
In metabolic disease, astaxanthin reduces lactate and carbohydrate (CHO) oxidation, while increasing fat oxidation, suggesting improved metabolic efficiency. In relation to exercise, astaxanthin enhances mitochondrial protection and biogenesis, boosts capillary blood flow, and improves oxygen delivery, all of which could lead to better endurance and ...

Feeding behavior of brown trout, Salmo trutta fario, during spawning season in four rivers of Lar National Park, Iran

open access: yesCaspian Journal of Environmental Sciences, 2011
Brown trout, Salmo trutta fario, has a wide range of distribution in the north of Iran and in Karaj, Lighvanchai and Karun Rivers, but there is no report about its feeding behavior in some water resources including the Lar Natural Park.

Local environment and sampling bias drive parasite prevalence estimates in freshwater fish communities

open access: yesOikos, Volume 2025, Issue 7, July 2025.
Parasite occurrence and infection estimates vary through time and space, making understanding the underlying drivers highly complex. Comparative studies based on empirical data must consider the factors of variation involved in estimating infection metrics in natural populations to make appropriate and reliable comparisons. Using a multi‐scale approach,
