Deep, diverse and definitely different: unique attributes of the world's largest ecosystem
Abstract. The deep sea, the largest biome on Earth, has a series of characteristics that make this environment both distinct from other marine and land ecosystems and unique for the entire planet.Expand
The biodiversity of the deep Southern Ocean benthos
TLDR
The general biodiversity patterns of meio-, macro- and megafaunal taxa are described, based on historical and recent expeditions, and against the background of the geological events and phylogenetic relationships that have influenced the biodiversity and evolution of the investigated taxa. Expand
Sequence and analysis of chromosome 4 of the plant Arabidopsis thaliana
TLDR
Analysis of 17.38 megabases of unique sequence, representing about 17% of the Arabidopsis genome, reveals 3,744 protein coding genes, 81 transfer RNAs and numerous repeat elements. Expand
First insights into the biodiversity and biogeography of the Southern Ocean deep sea
TLDR
New data from recent sampling expeditions in the deep Weddell Sea and adjacent areas reveal high levels of new biodiversity, challenging suggestions that deep-sea diversity is depressed in the Southern Ocean and providing a basis for exploring the evolutionary significance of the varied biogeographic patterns observed in this remote environment. Expand
Higher classification of the flabelliferan and related Isopoda based on a reappraisal of relationships
TLDR
Morphological characters are used to explore relationships between 35 genus-, family- and suborder-level taxa of flabelliferan Isopoda in a cladistic analysis and to derive a new classification, and unambiguous relationships between most families are resolved. Expand
Brooding and Species Diversity in the Southern Ocean: Selection for Brooders Or Speciation within Brooding Clades?
TLDR
Some evidence supports the three vicariant hypotheses, with the ACC hypothesis perhaps the best predictor of observed patterns, both the unusual number of species with nonpelagic development and the notably high biodiversity found in the Southern Ocean. Expand
On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)*
TLDR
This analysis demonstrates that the origin of the Antarctic fauna probably has different roots: an adaptive radiation of descendants from old Gondwanian ancestors was hypothesized for the isopod families Serolidae and Arcturidae, an evolution and radiation of phylogenetically old taxa in Antarctica could also be shown for the Ostracoda and the amphipod family Iphimediidae. Expand
Diversity and species distribution of polychaetes, isopods and bivalves in the Atlantic sector of the deep Southern Ocean
TLDR
The impact of depth on species richness was not consistent among groups; polychaetes showed a negative relationship to depth, isopods displayed highest richness in the middle depth range (2,000–4,000 m), whereas bivalves showed no clear relationship todepth. Expand
