The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

Marine zooplankton comprise a phylogenetically and functionally diverse assemblage of
protistan and metazoan consumers that occupy multiple trophic levels in pelagic food webs …

The hadal zone represents one of the last great frontiers in marine science, accounting for
45% of the total ocean depth range. Despite very little research effort since the 1950s, the …

Among marine organisms, gelatinous zooplankton (GZ; cnidarians, ctenophores, and
pelagic tunicates) are unique in their energetic efficiency, as the gelatinous body plan allows …

Changes in two contrasting ecosystems of the Benguela upwelling region, one dominated at
mid-trophic level by jellyfishes (Namibia, northern Benguela ecosystem, where small pelagic …

Resource subsidies in the form of allochthonous primary production drive secondary
production in many ecosystems, often sustaining diversity and overall productivity. Despite …

Deep-sea trenches remain one of the least explored ocean ecosystems due to the unique
challenges of sampling at great depths. Five submersible dives conducted using the …

Jellyfish blooms are common in many oceans, and anthropogenic changes appear to have
increased their magnitude in some regions. Although mass falls of jellyfish carcasses have …

ABSTRACT A majority of the world's largest net-based fisheries target planktivorous forage
fish that serve as a critical trophic link between the plankton and upper-level consumers …

Abstract Gelatinous zooplankton (Cnidaria, Ctenophora, and Urochordata, namely,
Thaliacea) are ubiquitous members of plankton communities linking primary production to …
