To date, little research has been carried out on pelagic gastropod molluscs (pteropods) in
Southern Ocean ecosystems. However, recent predictions are that, due to acidification …

Kelp forests are enormously productive, and they and adjacent habitats support large
populations of suspension feeders. What do these suspension feeders eat? Intuitively, we …

We measured the concentrations of Cr, Fe, Ni, Cu, Zn, Cd, Pb and Hg, and the stable isotope
ratios (δ 13 C and δ 15 N) in 87 fish samples within 12 economic fish species collected from …

It has been hypothesized that the high diversity of giant kelp forests is due primarily to the
provision of energy and habitat by the giant kelp (Macrocystis pyrifera). In this article, I use a …

Stable carbon isotope signatures (δ 13 C) are increasingly being used to determine the
foraging habitats of consumers in the Southern Ocean. An underlying assumption is that a …

Seaweed assemblages represent the dominant autotrophic biomass in many coastal
environments, playing a central structural and functional role in several ecosystems. In …

The giant kelp Macrocystis is the world's largest benthic organism and most widely
distributed kelp taxon, serving as the foundation for diverse and energy-rich habitats that are …

Samples of kelp Laminaria hyperborea, various species of red algae, phytoplankton,
material from sediment traps, invertebrates, fish and seabirds were collected on the west …

Do large organisms occupy higher trophic levels? Predators are often larger than their prey
in food chains, but empirical evidence for positive body mass–trophic level scaling for entire …

The effects of freezing, oven-drying, and formalin and ethanol preservation on stable isotope
signatures of 3 unrelated marine species (fish, octopus and kelp) were studied over a period …
