Sparse genetic data limit biodiversity assessments in protected areas globally

open access: yesFrontiers in Ecology and the Environment, Volume 23, Issue 8, October 2025.
Global conservation targets include protecting genetic diversity within species. Yet few studies have assessed whether protected areas (PAs) include genetically diverse populations across species globally. A first step is understanding the availability of population genetic data that could be used in these assessments.

Anthozoan eDNA primer set characterizes Ctenophora and Medusozoa inhabiting mesophotic and deep waters off the Gulf Coast of the southern USA

open access: yesFrontiers in Marine Science
While gelatinous zooplankton (GZ) constitute a vital component of the marine food web, understanding their biology and ecology has been hindered because traditional collection methods often destroy their fragile bodies.

A study on the biodiversity of benthic invertebrates in the waters of Seogwipo, Jeju Island, Korea

open access: yesJournal of Asia-Pacific Biodiversity, 2014
The biodiversity of benthic invertebrates in the intertidal and subtidal regions of Gapado, Beomseom, and Munseom islets was surveyed twice in May and September 2013 to study the state of biodiversity in Seogwipo, Jeju Island.

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa

open access: yesEvoDevo, 2010
Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.

Beyond synapses: cytoplasmic connections in brain function and evolution

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2055-2070, October 2025.
ABSTRACT Following Ramón y Cajal's groundbreaking contributions to the identification of synapses, research in neuroscience predominantly focused on their pivotal role in neural communication (the neuron doctrine), overlooking an intriguing possibility suggested by Golgi of non‐synaptic interactions among neural cells.

The evolution of reproduction in Ediacaran–Cambrian metazoans

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Characterizing Rocky Intertidal Biodiversity Using Environmental DNA Metabarcoding From Local to National Scales

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
We assess the resolution of eDNA metabarcoding for detecting rocky intertidal taxa across three spatial scales—national, regional, and local. Distinct eDNA signals were observed at each scale, with community differences more pronounced at broader scales.

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 ...

Limited Dispersal of Benthic Environmental DNA From a Subtropical Mesophotic Shelf‐Edge Bank

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated the vertical and horizontal dispersion of eDNA away from an isolated mesophotic coral reef (Bright Bank) in stratified offshore waters. We found that vertical transport of benthic eDNA was limited by water column stratification and that the prevalence of eDNA from benthic invertebrates declined with horizontal distance away from the ...
