Comparative Multi‐Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Comparative study of Hippo pathway genes in cellular conveyor belts of a ctenophore and a cnidarian

open access: yesEvoDevo, 2016
Background The Hippo pathway regulates growth rate and organ size in fly and mouse, notably through control of cell proliferation. Molecular interactions at the heart of this pathway are known to have originated in the unicellular ancestry of metazoans ...

Accounting for Intra‐ and Intergenomic Sequence Variation in Reference Barcodes Improves eDNA Metabarcoding Biodiversity Assessment

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Environmental DNA (eDNA) metabarcoding can rapidly characterise biodiversity, yet its accuracy and effectiveness are limited by incomplete DNA barcode reference databases. We evaluated how comprehensive reference databases that include sequence variation within genomes (intragenomic) and across individuals and species (intergenomic) improve ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Cortical cytasters: a highly conserved developmental trait of Bilateria with similarities to Ctenophora

open access: yesEvoDevo, 2011
Background Cytasters (cytoplasmic asters) are centriole-based nucleation centers of microtubule polymerization that are observable in large numbers in the cortical cytoplasm of the egg and zygote of bilaterian organisms.
