Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]
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,

Three marker genes targeting prokaryotic, eukaryotic, and vertebrate diversity were used to assess biodiversity within Stellwagen Bank National Marine Sanctuary. High levels of biodiversity were seen across the sampled area, with distinct communities across surface water, bottom water, and sediment.

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

Invertebrate Bile Acid‐Sensitive Ion Channels and Their Emergence in Bilateria
This graphical abstract presents the evolutionary distribution and functional characteristics of bile acid‐sensing ion channels (BASICs) across bilaterians. A phylogenetic tree illustrates the presence of BASICs in diverse groups, extending beyond previously established mammalian findings.

The origin of the Hox/ParaHox genes, the Ghost Locus hypothesis and the complexity of the first animal [PDF]
A key aim in evolutionary biology is to deduce ancestral states in order to better understand the evolutionary origins of clades of interest and the diversification process(es) that have elaborated them.

Feeding ecology of juvenile Pacific salmon (Oncorhynchus spp.) in a northeast Pacific fjord: diet, availability of zooplankton, selectivity for prey, and potential competition for prey resources [PDF]
We investigated the feeding ecology of juvenile salmon during the critical early life-history stage of transition from shallow to deep marine waters by sampling two stations (190 m and 60 m deep) in a northeast Pacific fjord (Dabob Bay, WA) between May ...
