Diverse approaches to questions of Biodiversity: German contributions to studies of Marine Benthos around South America and Antartica

A look at the latitudinal gradient from North America via South America to Antarctica supports the impression that the ecosystems of this part of the world provide perfect conditions for marine biodiversity studies. Several bilateral or international initiatives with major German contributions have...
