A sedimentary DNA record of the Atacama Trench reveals biodiversity changes in the most productive marine ecosystem

Global Change Biology, Volume 30, Issue 7, July 2024.
Using DNA deposited in deep‐sea sediments, we examine how marine biodiversity has changed over the last 150 years in Chilean waters. We find a unique period aligning with high fishing and extreme climatic events that reduces overall diversity. Furthermore, we find an effect of sea surface temperature and El Nino events over diversity, providing an idea

Update of the risk assessment of polybrominated diphenyl ethers (PBDEs) in food

EFSA Journal, Volume 22, Issue 1, January 2024.
Abstract The European Commission asked EFSA to update its 2011 risk assessment on polybrominated diphenyl ethers (PBDEs) in food, focusing on 10 congeners: BDE‐28, ‐47, ‐49, ‐99, ‐100, ‐138, ‐153, ‐154, ‐183 and ‑209. The CONTAM Panel concluded that the neurodevelopmental effects on behaviour and reproductive/developmental effects are the critical ...

FECUNDIDAD DEL JUREL ALETA AMARILLA, CARANX HIPPOS (LINNAEUS) EN EL CARIBE COLOMBIANO

Bulletin of Marine and Coastal Research, 2016
Caranx hippos is one of the most important fish resources in Colombia, particularly in artisanal fisheries. In order to deepen C. hippos biological knowledge, fecundity (number of eggs in development) and oocyte diameter was estimated. Fish samples were collected from commercial artisanal fishing trips, each fish was measured (total length, Lt) and ...
