Amathamide alkaloids in the pycnogonid, Stylopallene longicauda, epizoic on the chemically defended bryozoan, Amathia wilsoni [PDF]

open access: yes, 1998
Amathamides comprise a group of brominated alkaloids found in the bryozoan, Amathia wilsoni Kirkpatrick (Gymnolaemata: Ctenostomata). We tested a crude bryozoan extract and purified amathamide C for their ability to deter feeding by fish, Acanthaluteres ...

Food web trophic control modulates tropical Atlantic reef ecosystems response to marine heat wave intensity and duration

open access: yesJournal of Animal Ecology, Volume 94, Issue 8, Page 1492-1506, August 2025.
In this study we showed that trophic control modulates the effects of marine heatwaves (MHWs) on species biomass dynamics in a tropical and pristine Atlantic reef ecosystem. Our study provides insights into how the strength of predator–prey interactions may generate different outcomes in face of intensified and prolonged MHWs. Abstract Marine heatwaves
