Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping
Remote Sensing in Ecology and Conservation, EarlyView.Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

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

Frontiers in Neuroscience, 2023 Cilia are the major effectors in Ctenophores, but very little is known about their transmitter control and integration. Here, we present a simple protocol to monitor and quantify cilia activity and provide evidence for polysynaptic control of cilia ...

Adult and offspring size in the ocean over 17 orders of magnitude follows two life history strategies [PDF]
, 2015 Explaining variability in offspring vs. adult size among groups is a necessary step to determine the evolutionary and environmental constraints shaping variability in life history strategies.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia
Zoologica Scripta, EarlyView.ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Extensive mitochondrial gene rearrangements in Ctenophora: insights from benthic Platyctenida
BMC Evolutionary Biology, 2018 Background Complete mitochondrial (mt) genomes have been sequenced for thousands of animals and represent a molecule of choice for many evolutionary studies. Nevertheless, some animal groups have remained under-sampled.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]
, 1987 The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,
