The Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

Highly Expressed Genes in Marine Sponge Suberites domuncula Prefer C- and G-Ending Codons

open access: yesFood Technology and Biotechnology, 2009
Sponges are the simplest extant phylum of Metazoa; they are closest to the common ancestor of all multicellular animals. A total of 223 coding sequences from Suberites domuncula (Demospongiae) represent the dataset for the codon usage analysis.

Hyperdiverse Macrofauna Communities Associated with a Common Sponge, Stylissa carteri, Shift across Ecological Gradients in the Central Red Sea

open access: yesDiversity, 2019
Sponges act as important microhabitats in the marine environment and promote biodiversity by harboring a wide variety of macrofauna, but little is known about the magnitude and patterns of diversity of sponge-associated communities.

Evolution of g-type lysozymes in metazoa: insights into immunity and digestive adaptations

open access: yesFrontiers in Cell and Developmental Biology
Exploring the evolutionary dynamics of lysozymes is critical for advancing our knowledge of adaptations in immune and digestive systems. Here, we characterize the distribution of a unique class of lysozymes known as g-type, which hydrolyze key components

Porifera

open access: yes, 2014
Los organismos agrupados en el Phylum PORIFERA (del griego, πόρος [poros]= canal, pasaje y φέρ [phero]=llevar) son vulgarmente conocidos bajo el nombre de ¨esponjas¨ son exclusivamente acuáticos. Las distintas especies se encuentran distribuidas en ambientes marinos desde las profundidades abisales hasta los intermareales, con un pequeño grupo que ...
