Stable isotopes reveal that gelatinous zooplankton diets group by taxonomy and feeding traits in a coastal upwelling system

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Gelatinous zooplankton are abundant in marine ecosystems, yet their trophic roles and functional diversity in food webs have only recently gained attention. Gelatinous zooplankton taxa including hydromedusae, ctenophores, siphonophores, chaetognaths, and pelagic tunicates span multiple phyla and are often grouped taxonomically, but trait‐based

Ecology and genetics of Mnemiopsis leidyi A. Agassiz 1865: a field study on the invasive ctenophore in North Europe [PDF]

open access: yes
Mnemiopsis leidyi A. Agassiz 1865 is an American ctenophore that has invaded European waters in the last decades. The reliable, but still debated, relationship between this invasion and the collapse of the stocks of anchovy Engraulis encrasicolus ...

New genomic data and analyses challenge the traditional vision of animal epithelium evolution

open access: yesBMC Genomics, 2018
Background The emergence of epithelia was the foundation of metazoan expansion. Epithelial tissues are a hallmark of metazoans deeply rooted in the evolution of their complex developmental morphogenesis processes.

A late-surviving stem-ctenophore from the Late Devonian of Miguasha (Canada)

open access: yesScientific Reports, 2021
Like other soft-bodied organisms, ctenophores (comb jellies) produce fossils only under exceptional taphonomic conditions. Here, we present the first record of a Late Devonian ctenophore from the Escuminac Formation from Miguasha in eastern Canada. Based

Parallel evolution of gravity sensing

open access: yesFrontiers in Cell and Developmental Biology
Omnipresent gravity affects all living organisms; it was a vital factor in the past and the current bottleneck for future space exploration. However, little is known about the evolution of gravity sensing and the comparative biology of gravity reception.

Evaluating 18S Phylogenetic Placement Accuracy to Uncover Hidden Diversity in Non‐Bilaterian Animals

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
We assembled the largest curated non‐bilaterian 18S reference dataset and demonstrate that barcode choice strongly influences phylogenetic placement accuracy. Full‐length 18S provides the most robust framework for biodiversity discovery, recovering previously unknown non‐bilaterian lineages, whereas V9 should be interpreted with caution. ABSTRACT Small
