Taxonomy of North American fish Eimeriidae [PDF]

open access: yes, 1984
Taxonomic descriptions, line drawings, and references are given for the 30 named and 5 unnamed species of North American fish Eimeriidae. In addition, a key was developed based on available morphologic data to distinguish between similar species.

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

open access: yes, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...

Biological aspects and population dynamics of the European pilchard Sardina pilchardus (Walbaum, 1792) in the southeastern Mediterranean waters

open access: yesJournal of Fish Biology, Volume 108, Issue 4, Page 1072-1086, April 2026.
Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

Primer Length in Reverse Transcription Determines Biodiversity Recovery and Reproducibility in eRNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Primer length for reverse transcription significantly affects eRNA‐based biodiversity recovery and community structure. Shorter primers, particularly N4 and N5, in random priming and medium‐length primers, particularly T20, in oligo(dT) priming demonstrate superior performance, especially in detecting the rare biosphere.

Evaluating the Potential for Citizen Science Divers to Monitor Fish Biodiversity Through Passive eDNA Collection

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Passive capture of eDNA can be used as a tool for citizen scientist SCUBA divers to supplement visual surveys for marine species detection and is particularly useful for species that are rare or visually inaccessible to divers. ABSTRACT Environmental DNA (eDNA) marker gene sequencing, or metabarcoding, can be a powerful tool for monitoring marine ...
