This study investigates the deep‐sea food‐web at the South Sandwich Islands in the Southern Ocean, focusing on how net primary production drives interannual changes in food chain length and overall…
Cephalopods (squid and octopods) play an essential role in the Southern Ocean’s ecosystem, acting as a link between lower trophic levels and top predators. However, their ecological role in the…
Mercury (Hg) is a toxic metal, which as seen its concentrations increase in the environment due to anthropogenic activities. It bioaccumulates in organisms throughout life and biomagnifies in food webs,…
The article examines how climate change and warming Southern Ocean waters can increase the availability of mercury (Hg) in the Antarctic marine food web, due to the release of ice-stored…
Squid species in the Southern Ocean play a crucial role in the ecosystem by acting as a link between lower trophic levels and top predators. Despite their importance, there have…
Trace and rare earth elements compounds present in the marine environment are mainly transferred through the diet of organisms. Given the significance of seafood as a source of essential nutrients…
Since the Industrial Revolution, mercury (Hg) concentrations in the environment have been increasing due to anthropogenic activities. The toxic effect that this metal has on animals and humans led to…
The report by the Arctic Council (Protection of the Arctic Marine Environment, PAME) explains how indigenous populations are being affected by climate change. The rapid increase in temperature occurring in…
At the present time, climate change is an undeniable fact, with global ocean warming and Polar ice melting among the most notable consequences. In this context, the increased temperature in…
Penguins, one of the most abundant groups of seabirds in the Southern Ocean, feed mainly on cephalopods (e.g., squids and octopus). A recent study, led by our Hugo Guímaro, studied…
