Surveying Biodiverse Coral Reef Ecosystems Across the Tree of Life With Environmental DNA

open access: yesMolecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT A central challenge in evaluating biodiversity using environmental DNA (eDNA) metabarcoding is that each primer set has biases resulting in selective amplification of taxonomic diversity. Here we test 11 primer pairs to assess Central Pacific coral reef diversity in the five kingdoms of marine eukaryotes: Chromista, Fungi, Metazoa, Plantae and

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 10, Page 2895-2908, October 2026.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

Aging Disrupts Tissue Homeostasis and Constrains Blastema‐Mediated Regeneration in the Cladonema Medusa

open access: yesAging Cell, Volume 25, Issue 10, October 2026.
Aging in Cladonema medusae disrupts tissue homeostasis and stem cell‐associated dynamics, accompanied by delayed wound closure and defective blastema formation. These age‐associated cellular changes culminate in incomplete functional tentacle regeneration, revealing how aging constrains regenerative capacity in a highly regenerative cnidarian ...

A guideline to nematocyst nomenclature and classification, and some notes on the systematic value of nematocysts

open access: yesScientia Marina, 2000
Cnidocyst nomenclature is based on the structure of the tubule and its armature as viewed in the light microscopy (LM). Investigations utilising optically improved LM and scanning electron microscopy have revealed some errors in the interpretation of the

Complete mitochondrial genome of Carijoa riisei (Duchassaing & Michelotti, 1860) (Octocorallia: Alcyonacea: Stolonifera: Clavulariidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
We report the first complete Stolonifera mitochondrial genome. Carijoa riisei (Duchassaing & Michelotti, 1860) isolate CLP2_A03 was collected by scuba at 32 m on the USTS Texas Clipper (27° 53.7827′N, 93° 36.2702′W).

Citizen Sailors Provide a Detailed Map of Open‐Ocean Surface Biodiversity and Help Link eDNA Data to Satellite Observations

open access: yesMolecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Characterizing open ocean biodiversity at basin scales remains challenging due to sparse sampling and limited opportunities to validate satellite‐derived estimates of plankton community composition. Through the Citizens of the Sea initiative, we deployed standardized environmental DNA (eDNA) sampling kits on 27 sailing vessels during the 2024 ...

A DRACH Observed/Expected Metric Reveals the Evolutionary Landscape of Epitranscriptomic Regulation Across Bilateria

open access: yesAnnals of the New York Academy of Sciences, Volume 1564, Issue 1, October 2026.
Epitranscriptomic marks are highly variable across life stages and tissues, complicating comparisons between species. Using m6A consensus motifs, we developed a genomic indicator reflecting transcript methylability, the DRACH o/e score, that we used to investigate epitranscriptomic features and associated functions across nine bilaterian species.
