In the 1950s, the Danish Galathea Expedition undertook one of the first and most
comprehensive explorations of our ocean's hadal zone, depths extending from 6,000 to …

The deepest marine ecosystem, the hadal zone, hosts endemic biodiversity resulting from
geographic isolation and environmental selection pressures. However, the pan-ocean …

Abstract The South Sandwich Trench is a 965 km long arcuate subduction trench spanning
the South Atlantic and Southern oceans, isolated from most other hadal (areas where water …

The hadal zone (depths> 6000 m) comprises isolated features that host high degrees of
endemism, with species inhabiting only a single feature or a group of adjacent features. The …

Abstract Valettietta Lincoln & Thurston, 1983 (Amphipoda: Alicelloidea) is an infrequently
sampled genus of scavenging amphipod, with a known bathymetric range from 17–5467 m …

The deep ocean is a vast reservoir of new species to science, and each discovery improves
our ecological understanding of these remote ecosystems. One island-like ecosystem is the …

Alicella gigantea, the largest amphipod scavengers found to date, play key roles in the food
web of the hadal ecosystem. However, the genetic structure of A. gigantea populations …

Hadal zones are unique habitats characterized by high hydrostatic pressure (HHP) and
scarce food supplies. The ability of eggs of species dwelling in hadal zones to develop into …

Hadal trenches are a unique habitat with high hydrostatic pressure, low temperature and
scarce food supplies. Amphipods are the dominant scavenging metazoan species in this …

The examination of genetic structure in the deep‐ocean hadal zone has focused on
divergence between tectonic trenches to understand how environment and geography may …
