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

Marine Sponge Derived Natural Products between 2001 and 2010: Trends and Opportunities for Discovery of Bioactives

open access: yesMarine Drugs, 2014
Marine sponges belonging to the phylum Porifera (Metazoa), evolutionarily the oldest animals are the single best source of marine natural products.

Assessing the Potential of Sponges (Porifera) as Indicators of Ocean Dissolved Si Concentrations

open access: yesFrontiers in Marine Science, 2017
We explore the distribution of sponges along dissolved silica (dSi) concentration gradients to test whether sponge assemblages are related to dSi and to assess the validity of fossil sponges as a palaeoecological tool for inferring dSi concentrations of ...

Moss‐Accumulated eDNA Is a Promising Source for Terrestrial Biodiversity Surveys Across the Tree of Life and Biomes

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Developments in the environmental DNA (eDNA) field have revolutionised our ability to map biodiversity by providing cost‐effective and non‐invasive means to survey organisms across the tree of life. In the terrestrial realm, a variety of eDNA sources have been employed, but we lack easily accessible and cosmopolitan sources of terrestrial eDNA.

Genomic Connectivity and Adaptation Signals of the Freshwater Sponge Ephydatia muelleri Across Its Distribution

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Genetic connectivity and local adaptation were examined across the distribution of the freshwater sponge Ephydatia muelleri. Because it occupies an exceptional breadth of freshwater environments across a broad geographic range, this species offers key insights into biogeographic processes shaping genetic structure and adaptation in inland ...

Moving Beyond Morphology: Genomic Insights Into Evolutionary Histories of Haplosclerid Sponges

open access: yesZoologica Scripta, Volume 55, Issue 1, Page 177-194, January 2026.
ABSTRACT Accurate taxonomic identification is essential for defining species boundaries and understanding biodiversity. However, this remains challenging for groups where morphological character evolution is poorly understood or diagnostic traits are absent.

Spongivory by Fishes on Southwestern Atlantic Coral Reefs: No Evidence of Top-Down Control on Sponge Assemblages

open access: yesFrontiers in Marine Science, 2018
Predator-prey dynamics can affect assemblage structure and ecosystem processes representing a central theory in ecology. In coral reef ecosystems, recent evidences have suggested that sponge assemblages in regions with high diversity, like the Caribbean,

Alkaloids Isolated From the Gastropod Reishia clavigera: Their Antibacterial and Cytotoxic Activities

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Reishia clavigera, an edible marine gastropod consumed in Asia and used in traditional medicine, was investigated for its secondary metabolite content. Despite its widespread consumption and ethnomedicinal use, no comprehensive study has examined the secondary metabolites from whole‐body extracts.

Physiology and Evolution of Voltage-Gated Calcium Channels in Early Diverging Animal Phyla: Cnidaria, Placozoa, Porifera and Ctenophora

open access: yesFrontiers in Physiology, 2016
Voltage-gated calcium (Cav) channels serve dual roles in the cell, where they can both depolarize the membrane potential for electrical excitability, and activate transient cytoplasmic Ca2+ signals.
