Detection and succession properties of forested vernal pools with eDNA metabarcoding

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We examined the capacity of environmental DNA metabarcoding for studying biodiversity of forested vernal pools, using multiple assays to investigate different eukaryotic communities over space and time. Our results suggest that metabarcoding can serve as a complementary tool for ‘scaling up’ vernal pool biodiversity monitoring, illuminating ecological ...

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.

Copepod fauna (Calanoida and Cyclopoida) in small ponds of the Pollino National Park (South Italy), with notes on seasonality and biometry of species

open access: yesJournal of Limnology, 2006
The plankton copepod fauna of the Pollino National Park (South Italy) were studied for the first time. Plankton samples were collected from 5 ponds, and 2 of these ponds were sampled monthly for one year to study species’ seasonality. The length of adult

Conception of Crossed Populations: Application in Cyclopoida Taxonomy

open access: yesVestnik Zoologii, 2009
Conception of Crossed Populations: Application in Cyclopoida TaxonomyThe conception of crossed populations in wide practice of taxonomic investigations in Cyclopoida is used for the first time. Applying this conception in taxonomy of cyclopoid copepods we based on revealed facts of the coexistence of sibling species which keep a little morphological ...
