Evo-Devo in Ophiuroids: The Switch from Planktotrophy to Lecithotrophy in < em > Ophionereis < /em >
Biol Bull. 2023 Jun;244(3):164-176. doi: 10.1086/727755. Epub 2023 Oct 30.ABSTRACTAbstractUnderstanding the evolution of development (evo-devo) in the Ophiuroidea and the pathways in the switch from a feeding to a nonfeeding larva is complicated by the variability in the phenotype of the metamorphic larva, being a reduced yolky ophiopluteus in some species (type I development) and a vitellaria larva in others (type II development). We investigated evo-devo in the family Ophionereididae, a group dominated by lecithotrophic development through a vitellaria larva. We reared the planktotrophic larvae of Ophionereis fasciata to...

The Effects of Social Experience on Host Gut Microbiome in Male Zebrafish ( < em > Danio rerio < /em > )
Biol Bull. 2023 Jun;244(3):177-189. doi: 10.1086/729377. Epub 2024 Feb 20.ABSTRACTAbstractAlthough the gut and the brain vastly differ in physiological function, they have been interlinked in a variety of different neurological and behavioral disorders. The bacteria that comprise the gut microbiome communicate and influence the function of various physiological processes within the body, including nervous system function. However, the effects of social experience in the context of dominance and social stress on gut microbiome remain poorly understood. Here, we examined whether social experience impacts the host zebrafish (...

Gonadal Degeneration Is Mediated by Apoptotic Processes in the Semelparous Gray Side-Gilled Sea Slug < em > Pleurobranchaea maculata < /em >
Biol Bull. 2023 Jun;244(3):190-200. doi: 10.1086/727971. Epub 2023 Nov 9.ABSTRACTAbstractSpecies undergoing postreproductive death experience great changes in their reproductive organs, which are driven by numerous physiological processes. To assess whether apoptotic processes are involved in the dynamics of the reproductive organs of Pleurobranchaea maculata, the gonadal structure of this semelparous side-gilled sea slug was studied using light and scanning electron microscopy. Apoptotic cells at different gonadal developmental stages were detected by in situ TUNEL assay. Apoptosis was primarily focused on spermatogonia d...

A Decade of Death and Other Dynamics: Deepening Perspectives on the Diversity and Distribution of Sea Stars and Wasting
Biol Bull. 2023 Jun;244(3):143-163. doi: 10.1086/727969. Epub 2023 Dec 22.ABSTRACTAbstractMass mortality events provide valuable insight into biological extremes and also ecological interactions more generally. The sea star wasting epidemic that began in 2013 catalyzed study of the microbiome, genetics, population dynamics, and community ecology of several high-profile species inhabiting the northeastern Pacific but exposed a dearth of information on the diversity, distributions, and impacts of sea star wasting for many lesser-known sea stars and a need for integration across scales. Here, we combine datasets from single-s...
