Developmental Dynamics, Volume 254, Issue 8, Page 887-901, August 2025.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Repeated hurricane disturbance has minimal impact on shallow coastal infaunal communities
Ecosphere, Volume 16, Issue 7, July 2025.Abstract Disturbances are important drivers of seafloor community structure and diversity, especially in sediment infaunal communities with limited mobility. Shallow coastal sediment communities contribute to global nutrient cycling and carbon storage but also experience large‐scale disturbances, including storms.

Comparative 3D‐anatomy of Appendicularian Endostyles (Tunicata, Chordata) ‐ A Tale of Reduction
Journal of Morphology, Volume 286, Issue 7, July 2025.Appendicularia are chordates that possess endostyles, a pharyngeal gland homologous to vertebrate thyroid. Here, we describe the detailed 3D‐anatomy of endostyles based on light‐ and electron microscopy. We identified seven cell types arranged in specific patterns.

Data for: Three amphioxus reference genomes reveal gene and chromosome evolution of chordates
, 2023 The slow-evolving invertebrate amphioxus has an irreplaceable role in advancing our understanding into vertebrate origin and innovations. Here we resolve the nearly complete chromosomal genomes of three amphioxus species, one of which best recapitulates ...

Journal of Fish Biology, Volume 107, Issue 1, Page 52-62, July 2025.Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...

Assaying Chromatin Accessibility Using ATAC-Seq in Invertebrate Chordate Embryos
Frontiers in Cell and Developmental Biology, 2020 Cis-regulatory elements (CREs) are non-coding DNA regions involved in the spatio-temporal regulation of gene expression. Gene regulatory changes drive animal development and play major roles during evolution of animal body plans.

Gene Duplication and Alternative Splicing as Evolutionary Drivers of Proteome Specialization
BioEssays, Volume 47, Issue 5, May 2025.Gene duplication and alternative splicing expand the proteome, enabling ancestral genes to shape cell type evolution without jeopardizing their ancestral role. But how, exactly? In this piece, we propose that expression and functional specialization are key, underappreciated fates for paralogous genes and alternative isoforms throughout animal ...
